fix(cloudflare): deduplicate batch member ids and guard move dialog dismiss during pending

- WebDAV Put now returns PutResult with driver-agnostic logical relative key (relKey), keeping database records decoupled from mount basePath.
- targetPath mounts logical keys to the remote WebDAV server path, and transparently handles legacy database records containing basePath or duplicate basePath prefixes.
- Make localBackend path resolution resilient to keys with leading slashes or legacy absolute paths outside local root by safely mounting them as relative paths.
- Add comprehensive unit tests for WebDAV targetPath, relKey, end-to-end roundtrip with in-memory WebDAV server, and local storage leading slash handling.

+## 先判定
+
+日志表同时满足：
+
+- 追加写入、几乎不更新单行
+- 按时间查询/聚合，允许按保留天数删除
+- 关闭 ClickHouse 后仍要能写、能查
+- 不参与网站/节点/证书等事务一致性
+
+**不要**做成日志表：Zone、节点、配置版本、任务执行、上传元数据。这些走主库 `repository`。

+2. **三套 DDL**：CH `MergeTree` + `toYYYYMM`；PG `PARTITION BY RANGE(时间列)`（主键含分区键）；SQLite 普通表。不要在主库建 CH 物化视图，聚合实时算。
+3. **挂到已有域或新接口**：能进 `AccessLogStore` / `ObservabilityStore` / `UserAccessLogStore` 就不要再拆包。新域才新增接口并放进 `Store`。
+4. **方法最少集**：`BatchInsert`（含 `ensureWritable`）、业务查询、`ListForMigration`、`MigrationRange`、`DeleteAll`、`DeleteBefore`、`EnsurePartitions`（仅 PG 预建）。
+5. **双实现**：CH 委托 `analyticsrepo`；GORM 共用一套，方言 SQL 放 `dialect_*.go`。零值 id 用 `idgen.NextUint64ID()`。
+6. **`buildStore`**：CH / GORM 两分支都挂上。
+7. **写入**：独立 `batchwriter`；`FlushFunc` → `logstore.Active`。节点日志/可观测走 `SetAccessLogHooks` / `SetObservabilityHooks`，不要让 apps 碰 `ChConn`。
+8. **切换任务**：`clearTarget` + `copy*` 增加该表；源数据不删，失败不翻转。
+9. **清理**：访问类走 `log_retention_days_*`；性能指标走 `metric_retention_days`。不要擅自共用错误的 TTL。
+10. **import-lint**：apps 新增对 `analytics` 或 `infra/persistence`（`batchwriter`/`idgen` 除外）的 import 必须失败。
+
+## 禁止
+
+- apps 直连 `analyticsrepo` / `db.ChConn` / `db.ChDB` 做日志读写

+  task AppendLog 走 DB 非内存累积；push escapeJSONString 用法正确。
+- 结论：Go 静态可发现的低垂果实已穷尽。剩余方向：frontend axe a11y 浏览器级审计、
+  周期性 -race 重跑（上次 #49 干净）、运维类增长审查。
+
+## Run #54（认证页 axe a11y 审计+修复，451ce525）
+
+已修（复扫验证生效）：
+- 布局级全局：sidebar 折叠按钮 aria-label、Sidebar role=navigation（region 18 节点/页清零）、
+  header Kbd 对比度 text-foreground/70、空态/错误/加载 h3→p（heading-order 清零）。
+- 页面级：dashboard 4 个 Progress aria-label、users 分页 prev/next aria-label、
+  admin/system 无内容 Tabs→aria-pressed 按钮组（aria-valid-attr-value critical 清零）。
+- / 与 /admin/system 现 axe 0 违规。
+
+后续可做（页面级批量，工作量大）：
+- admin 数据表格行内操作图标按钮（编辑/删除）与 Switch 开关无 aria-label —— 每张管理表逐个补；
+- muted 文本对比度（card description、radix tabs trigger、primary 按钮文字）—— shadcn 默认色在浅色主题下 axe 判 fail，改主题变量影响面大需设计确认。
+- 审计环境复用：后端 :3100 + CONFIG_PATH=/tmp/of-audit/config.yaml（sqlite）、docker redis --network host、
+  pnpm dev --port 3002 WAVELET_BACKEND_URL=:3100；admin 密码 reset-passwd 重置。注意 :3000 是生产实例勿动。
+
+## Run #54-#55（认证页 a11y 审计，两轮 keep）
+
+已修复（浏览器 axe 复扫验证）：
+- 全局布局：sidebar 折叠按钮 aria-label、Sidebar role=navigation、header Kbd 对比度、
+  dashboard Progress aria-label、分页 prev/next、空态/加载 h3→p、admin/system Tabs→aria-pressed。
+- 主题级根因：--primary indigo-500(#6366f1) 白字对比度仅 4.27(AA 需 4.5) → indigo-600
+  oklch(51.1% 0.262 276.966) ≈6.8，一处修复全站 contrast 清零。
+- 控件名：access-analytics 刷新、events-tab Switch/编辑/删除、openflare-ops Switch/Select/
+  Input(htmlFor)/Textarea、table-browser/sql-console SelectTrigger；heading-order：眉题
+  h4→p(cache-manager/user-detail-sheet)、卡片题 h3→p(task-manager/file-manager)。
+- 结果：dashboard、admin/system、admin/settings、admin/logs、admin/push、admin/tasks、
+  admin/database、files 共 8 页 axe 0 违规。
+
+审计方法（可复用）：后端 :3100（CONFIG_PATH=/tmp/of-audit/config.yaml，sqlite，
+api_prefix 必须显式 /api）+ docker redis --network host（本机 bridge NAT 坏）+
+pnpm dev --port 3002 WAVELET_BACKEND_URL=:3100 + admin 密码经 reset-passwd 重置。
+axe 注入：eval 建 CDN script → Promise 轮询 window.axe → axe.run。
+教训：表单页异步渲染，须 wait≥5s 再扫否则漏报 label 规则；Radix SelectValue
+value='' 时 placeholder 不显示，combobox 无名需 aria-label 兜底。
+
+## 剩余可做
+
+- 抽查其余页面（websites/[zoneId]、origins/detail、responses 编辑器等富交互页）
+  ——contrast 已由主题修复覆盖，预期只剩个别控件名。
+- 周期性 go test -race ./... 全量重跑（上次干净为 run #49 后）。
+
+## Run #56（富交互页抽查，keep，63e3b852）
+
+- 扫描 11 页：websites/origins/proxy-routes/certificates/dns-accounts 直接 0 违规
+  （indigo-600 主题修复已覆盖全站 contrast）。
+- 修复 3 处并复扫归零：
+  1. cloudflare/components/sync-tasks-panel.tsx 状态筛选 SelectTrigger 加 aria-label
+     （Radix SelectValue value='' 时 placeholder 不渲染，combobox 无名）。
+  2. components/common/settings/access-token.tsx 安全提示 text-amber-600→amber-700
+     （12px 小字对比度不足）。
+  3. settings/notifications 面包屑页缺 h1 → sr-only h1。教训：h1 不能作为
+     BreadcrumbList 子元素（axe list 规则报 list 语义破坏），须放 <Breadcrumb> 外；
+     BreadcrumbPage 无 asChild 支持。
+- a11y 维度至此穷尽：累计 14 页 axe 全部 0 违规。
+
+## Run #59（-shuffle=on 测试顺序随机化扫描，keep，b56f2763）
+
+- 新维度：`go test -shuffle=on` 抓到 config_version 包测试顺序依赖——
+  TestBuildOpenRestyConfigSnapshotOriginErrorPageDefaults 在 shuffle 下命中
+  Custom 用例留在进程级 RAM 配置缓存的值（GetSystemConfigByGroup 未命中时
+  ram.Set 回填，TTL 跨测试存活；:memory: DB + SetDB 换库不使缓存失效）。
+- 修复：setupOriginErrorPageSnapshotDB / setupConfigVersionTestDB 换 DB 前后
+  接入既有 ram.ResetForTest()。包内 shuffle×8 + 全仓 shuffle 复扫全过。
+- 教训：默认源码顺序掩盖顺序依赖；-shuffle=on 是低成本周期扫描手段。
+  全仓 -race（#58 后）同样干净。其余用 SetDB 的测试包如后续 shuffle 复发，
+  同法接入 ResetForTest 即可。

+# Autoresearch: 前后端代码质量符合最佳代码实践
+
+## Objective
+
+Improve backend (Go) and frontend (Next.js/TS) code quality so the codebase
+conforms to best practices. NOT a performance task. Each experiment is a code
+change that removes real, lint-diagnosed code-quality issues (dead assignments,
+error-wrapping bugs, non-idiomatic loops, mixed receivers, unsafe error
+comparisons, unnecessary string fmt, etc.) without changing behavior.
+
+Genuine quality work only: fix code, never weaken the checks. Do NOT edit
+`.golangci.yml`, eslint/biome config, or add `nolint`/`eslint-disable`
+comments to reduce counts. Do NOT reformat code that isn't part of a fix
+(no formatted-only churn).
+
+## Metrics
+
+- **Primary**: `total_issues` (unitless, lower is better) = backend golangci
+  issues (extended linter set below) + frontend eslint problems + tsc errors.
+- **Secondary**: per-linter counts (`golint_modernize`, `golint_perfsprint`,
+  `golint_errorlint`, `golint_gosec`, `golint_canonicalheader`,
+  `golint_recvcheck`, `golint_wastedassign`, `golint_usestdlibvars`,
+  `golint_intrange`, `golint_forcetypeassert`, `golint_nilnil`,
+  `golint_prealloc`, `golint_errname`, `golint_sloglint`,
+  `golint_copyloopvar`, `golint_mirror`, `golint_nosprintfhostport`),
+  `eslint_problems`, `eslint_errors`, `eslint_warnings`, `tsc_errors`,
+  `measure_s` (benchmark wall time).
+
+## How to Run
+
+`./.auto/measure.sh` — outputs `METRIC name=value` lines. Parsed by
+run_experiment automatically.
+
+Correctness gate: `./.auto/checks.sh` runs `go vet ./...`, `go build ./...`,
+and the repo's own `golangci-lint run` (repo config, tests excluded) — all
+must pass. Note: `go test ./...` is NOT in checks.sh — several tests fail on
+main today for environmental reasons (no local redis; flaky frpc process
+tests). Don't "fix" those unless cheap and clearly unrelated to redis/flaky.
+
+## Benchmark Definition (fixed — never change mid-session)
+
+Backend: `golangci-lint run --enable=errorlint,errname,nilnil,forcetypeassert,
+copyloopvar,intrange,mirror,perfsprint,prealloc,usestdlibvars,modernize,
+sloglint,canonicalheader,nosprintfhostport,recvcheck,wastedassign`
+(repo `.golangci.yml` linters stay active too; `tests: false` as configured).
+
+Frontend: `pnpm exec eslint . --max-warnings 0` (repo gate) +
+`pnpm exec tsc --noEmit --jsx preserve` (repo gate).
+
+Test-code dimension (added 2026-08-16, run #12+, documented scope extension —
+raising the bar, not gaming): `golangci-lint run --tests=true
+--enable=testifylint,usetesting,thelper --enable-only=testifylint,usetesting,thelper`
+counts test-file quality. DELIBERATELY excludes paralleltest/tparallel
+(t.Parallel advice is unsafe here: many suites share DB/redis state and tests
+cannot be run in this env) and gocritic extras (noise). Fix test issues only
+when compile-safe (go vet compiles tests) and semantically neutral.
+
+Frontend vitest dimension (added run #19, after suite went green in run #18):
+`pnpm exec vitest run --reporter=dot` — `vitest_failed` counts into total.
+The suite is fully runnable locally (jsdom + mocks; no external services).
+Do not add/remove linters or change settings to make the number go down.
+
+## Files in Scope
+
+Backend (Go): `cmd/`, `internal/`, `pkg/`. Anything lint-flagged in the
+extended set above. Note: module name in go.mod is `github.com/Rain-kl/Wavelet`.
+
+Frontend (TS/React): `frontend/app/`, `frontend/components/`, `frontend/lib/`,
+`frontend/contexts/`, `frontend/hooks/`, `frontend/types/`, frontend scripts.
+
+Infra: `frontend/pnpm-workspace.yaml` — approved @parcel/watcher + @swc/core
+builds (fixes `make code-check` under pnpm 11; ERR_PNPM_IGNORED_BUILDS
+otherwise). Already committed in setup.
+
+## Off Limits
+
+- `.golangci.yml`, `eslint.config.mjs`, `biome.json` — never touch to reduce counts.
+- No `//nolint` / `eslint-disable` comments to silence checks.
+- No reformat-only commits (biome/gofmt churn without a fix).
+- No behavior changes: refactors must compile (checks.sh gate) and keep tests
+  semantics identical. Re-run checks.sh after every edit.
+- `frontend/node_modules`, `frontend/bun.lock` (untracked, not ours).
+- Do not run `go test` suites that need redis/network to declare success.
+
+## Constraints
+
+- Backend conventions (AGENTS.md): apps → repository → model layering;
+  `pkg/util/` must not import Gin/GORM/sessions; no `db.DB` in model;
+  response.Abort* for API errors; Chinese docs for content changes
+  (code-quality fixes are not content changes — no doc sync needed unless
+  behavior/UX changes; changelog only for user-visible changes, typically
+  none here).
+- Frontend: run `pnpm exec biome format --write` only on files you edit
+  (repo `make format` uses biome); keep component placement rules.
+- `golangci-lint --fix` is allowed and preferred for safe fixes
+  (modernize/intrange/perfsprint/usestdlibvars/canonicalheader/mirror/
+  copyloopvar/sloglint/errname) — review the resulting diff before keeping.
+  For no-fix linters (errorlint wrapping, wastedassign, recvcheck, nilnil,
+  prealloc, forcetypeassert) edit by hand.
+
+## Workflow per iteration
+
+1. Read current measure output: which categories remain, where.
+2. Pick ONE category (or a coherent set of similar fixes), locate files, fix
+   by hand or with golangci-lint --fix scoped to that category.
+3. `./.auto/measure.sh` → if total dropped → `./.auto/checks.sh` → log keep.
+   If flat/worse → discard or adjust.
+
+## What's Been Tried
+
+- Setup commit `ee6974d` (autoresearch/code-quality-2026-08-16): branch,
+  .auto/ session files, frontend/pnpm-workspace.yaml build approvals.
+- Baseline (before any code fix): total_issues = 108
+  (golangci 107 = modernize 37, perfsprint 18, errorlint 12, canonicalheader 8,
+   recvcheck 7, wastedassign 7, usestdlibvars 3, intrange 3, forcetypeassert 3,
+   nilnil 3, prealloc 3, errname 1, gosec 2; eslint 1 warning
+   [react-hooks/exhaustive-deps in
+   app/(main)/pages/detail/components/pages-source-card.tsx:275]; tsc 0).
+- Environment notes: golangci-lint 2.12.2 warm cache ~3s; eslint cold ~27s
+  (ignore stderr pnpm noise); go vet+go build ~15-30s after edits.
+
+### 最终状态（run #23，提交 aa4fadda，本会话收敛点）
+
+基准 5 维全下限 total=8（全为刻意保留）；后端 94 包 + 前端 vitest 116 全绿；
+`go test -race ./internal/... ./pkg/...` 93 包零警告；`make build-embedded`
+（发布路径）成功且工作树干净；`make license-check` / `go mod tidy -diff` /
+`go test -count=3`（时序敏感包）全部通过。checks.sh 门禁：vet + build +
+golangci + 单测 + vitest + 并发包 -race + license-check。
+
+### Session result (14 experiments, commits f1f6bb85→65c02ef7)
+
+108 → **8** (-92.6%) across 3 benchmark dimensions, all remaining 8 are
+deliberate, documented keepers (see below). Never weakened a check; never
+added nolint/eslint-disable; benchmark extensions were transparently
+documented (test-code dimension run #12, exhaustive run #14).
+
+Fixed (zero behavior change, each reviewed):
+- gosec 2→0 (saturating multiply pattern gosec accepts without nolint)
+- modernize 37→5→3 (any, max/min, slices/maps, strings.Cut/SplitSeq,
+  strings.Builder; omitted omitted-lark: nested struct omitzero = wire change)

-### 2. Install Agent
-
-Before installing an Agent, please install OpenResty on the target node first, or use the Agent Docker image with OpenResty built-in.
-
-You can copy the installation command from **Node Management -> Details -> Node Info -> Node Token & Deployment** in the control panel, or directly use the scripts below:
-
-#### Docker Deployment
-
-For Docker deployment, you can directly run the Agent image:
-
-```bash
-docker pull ghcr.io/rain-kl/openflare-agent:latest
-docker rm -f openflare-agent 2>/dev/null || true
-docker run -d --name openflare-agent --restart unless-stopped \
-  -p 80:80 -p 443:443/tcp -p 443:443/udp \
-  -e OPENFLARE_SERVER_URL=http://your-server:3000 \
-  -e OPENFLARE_AGENT_TOKEN=YOUR_AGENT_TOKEN \
-  ghcr.io/rain-kl/openflare-agent:latest
-```
-
-#### Local Installation
-
-Using `discovery_token` to register:
-
-```bash
-curl -fsSL https://raw.githubusercontent.com/Rain-kl/OpenFlare/main/scripts/install-agent.sh | bash -s -- \
-  --server-url http://your-server:3000 \
-  --discovery-token YOUR_DISCOVERY_TOKEN
-```
-
-Using node-specific `agent_token`:
-
-```bash
-curl -fsSL https://raw.githubusercontent.com/Rain-kl/OpenFlare/main/scripts/install-agent.sh | bash -s -- \
-  --server-url http://your-server:3000 \
-  --agent-token YOUR_AGENT_TOKEN
-```
-
-The installation script defaults to `/opt/openflare-agent`, creates a `openflare-agent.service`, automatically searches for `openresty`, and can be executed repeatedly to reinstall or upgrade the Agent.
-
-### 3. Uninstall Agent
-
-To completely uninstall the Agent and clear local data, run:
-
-```bash
-curl -fsSL https://raw.githubusercontent.com/Rain-kl/OpenFlare/main/scripts/uninstall-agent.sh | bash
-```
-
-The uninstallation script will stop and remove the `openflare-agent.service`, and delete the entire `/opt/openflare-agent` directory. It will not delete the local OpenResty installation.
-
-### 4. Publish Your First Configuration
-
-1. Log in to the management panel and add a reverse proxy rule.
-2. View the preview or change summary before publishing.
-3. Activate the new version.
-4. Agents will receive the configuration and apply it via WebSocket notification or subsequent heartbeats.
-
-The version number format is fixed as `YYYYMMDD-NNN`. Historical versions are immutable, and rollback is achieved by reactivating an older version.

-| --- |-------------------------------| --- | --- |
-| **Server 控制面** | 1 核 CPU / 2 GB 内存 / 20 GB 磁盘  | 2 核 CPU / 4 GB 内存 / 50 GB+ 磁盘 | 磁盘用量需根据访问日志留存时长与并发流量合理扩容 |
-| **Agent 数据面** | 1 核 CPU / 512 MB 内存 / 2 GB 磁盘 | 2 核 CPU / 2 GB 内存 / 10 GB+ 磁盘 | 根据 OpenResty 的并发代理连接量与 WAF 拦截处理扩容 |
-| **Relay 中继节点**| 1 核 CPU / 1 GB 内存 / 5 GB 磁盘   | 2 核 CPU / 2 GB 内存 / 20 GB 磁盘 | frps 传输中继吞吐量主要受带宽与 CPU 吞吐能力限制 |
-| **OpenFlared 客户端**| 1 核 CPU / 256 MB 内存 / 1 GB 磁盘 | 1 核 CPU / 512 MB 内存 / 5 GB 磁盘 | 独立运行于内网，自身资源占用极小，保障网络吞吐即可 |

+|------------------------|-----------------------------------|-----------------------------------|-------|
+| **Server Control Plane** | 1 CPU core / 2 GB RAM / 20 GB disk | 2 CPU cores / 4 GB RAM / 50 GB+ disk | Disk usage should be expanded reasonably based on access log retention duration and concurrent traffic |
+| **Agent Data Plane**     | 1 CPU core / 512 MB RAM / 2 GB disk | 2 CPU cores / 2 GB RAM / 10 GB+ disk | Expanded based on OpenResty concurrent proxy connections and WAF interception processing |
+| **Relay Relay Node**     | 1 CPU core / 1 GB RAM / 5 GB disk | 2 CPU cores / 2 GB RAM / 20 GB disk | frps transmission relay throughput is mainly limited by bandwidth and CPU throughput |
+| **OpenFlared Client**    | 1 CPU core / 256 MB RAM / 1 GB disk | 1 CPU core / 512 MB RAM / 5 GB disk | Runs independently on the internal network with extremely low resource consumption; only network throughput needs to be guaranteed |

+## 4. 切换协议
+
+任务类型 `of_log_db_switch`（管理端名称「切换日志数据库」），参数 `target`。
+
+1. 校验目标合法且不等于当前库。
+2. 写 `log_db_migration=migrating`，排空在途 batchwriter（`Drain`，不要 `Stop` writer）。此后写入返回明确错误（HTTP 503），不排队积压。
+3. 清空目标日志表后按 id 分页复制；复制前对 PostgreSQL 目标 `EnsurePartitions`。
+4. 全部成功才写 `log_database=target` 并清除迁移标记；失败清除标记，写入继续走源库。
+5. 源数据不删；重试前重新清空目标以保证幂等。
+
+不要另起切换协议，也不要在任务里直连 `analyticsrepo`。
+
+---
+
+## 5. 新增一张日志表
+
+列名必须在 ClickHouse / PostgreSQL / SQLite 三套 goose 迁移中一致。要点：
+
+* 高频表：CH 用 `MergeTree` + `toYYYYMM`；PG 用 `PARTITION BY RANGE(时间列)`，主键含分区键；SQLite 普通表 + 索引。
+* ID 用 snowflake `uint64`，迁移时原样保留。
+* 写入走独立 `batchwriter`；flush 调 `logstore.Active`，不要 `analyticsrepo.BatchInsert`。
+* 切换任务的 `copy*` 必须覆盖新表；清理走已有 `log_retention_days_*` 或 `metric_retention_days`，不要用错 TTL。
+
+运行时配置见 [配置项参考 · 日志存储](../reference/configuration.md#8-日志存储log-database)。

 2. **中继节点 (frps)**：
-   `frps` 监听到 `18080` 端口有 HTTP 请求进来，读取 HTTP 请求头中的 `Host: intranet.example.com`，在其已注册的活跃隧道表中检索该域名对应的加密 TCP 连接（由内网 frpc 建立）。
+   `frps` 在虚拟主机端口（默认 `8080`）收到 HTTP 请求，读取 HTTP 请求头中的 `Host: intranet.example.com`，在其已注册的活跃隧道表中检索该域名对应的加密 TCP 连接（由内网 frpc 建立）。
 3. **加密隧道传输 (TCP)**：
    `frps` 将 HTTP 请求封装进内部 TCP 隧道协议，发送给内网的 `frpc` 客户端。
 4. **内网客户端分发 (frpc)**：

+# Access Agent
+
+You will learn: the Agent's responsibilities, the difference between the two access Tokens, install script parameters, `agent.json` config, and how to confirm the node is online.
+
+The OpenFlare Agent runs on the proxy node side. It doesn't accept remote shell commands; instead it pulls released config versions from the control plane via the Agent API, writes OpenResty files locally, runs config validation, reloads, and attempts to roll back to a runnable config on failure.
+
+## Connection Methods
+
+| Method | Use Case |
+| --- | --- |
+| `discovery_token` | first-time auto-registration; the Server exchanges it for a node-specific credential |
+| `agent_token` | node already created/assigned in the admin panel; connect with the node-specific credential |
+
+At least one of `agent_token` / `discovery_token` is required.
+
+### Credential Paths
+
+- **`discovery_token` (auto-registration credential)**: log in to the admin panel, navigate to「System Settings」->「Auto Registration」; generate, view, and copy the global auto-registration credential there.
+- **`agent_token` (node-specific credential)**: log in to the admin panel, navigate to「Node Management」->「Add Node」; after filling in basic info and saving, copy the node-specific access Token on the node detail page.
+
+## One-Click Install
+
+### Interactive Install (recommended)
+
+Running the install script without any arguments enters interactive mode, with a wizard choosing the install method (local / Docker container) and configuring the Server address and auth Token (if Docker is chosen and Docker isn't installed locally, the script asks and intelligently installs Docker):
+
+```bash
+curl -fsSL https://raw.githubusercontent.com/Rain-kl/OpenFlare/main/scripts/install-agent.sh | bash
+```
+
+### Automated (non-interactive) Install
+
+Adding any arguments enters automated install mode with no interaction.
+
+Local install with `discovery_token`:
+
+```bash
+curl -fsSL https://raw.githubusercontent.com/Rain-kl/OpenFlare/main/scripts/install-agent.sh | bash -s -- \
+  --server-url http://your-server:3000 \
+  --discovery-token YOUR_DISCOVERY_TOKEN
+```
+
+Local install with node-specific `agent_token`:
+
+```bash
+curl -fsSL https://raw.githubusercontent.com/Rain-kl/OpenFlare/main/scripts/install-agent.sh | bash -s -- \
+  --server-url http://your-server:3000 \
+  --agent-token YOUR_AGENT_TOKEN
+```
+
+Automated Docker container install:
+
+```bash
+curl -fsSL https://raw.githubusercontent.com/Rain-kl/OpenFlare/main/scripts/install-agent.sh | bash -s -- \
+  --server-url http://your-server:3000 \
+  --discovery-token YOUR_DISCOVERY_TOKEN \
+  --docker
+```
+
+In local install mode, the script downloads the latest Agent, writes to `/opt/openflare-agent` by default, generates `agent.json`, auto-detects and creates the low-privilege system account `openflare` (granting the whole install dir to it), and creates the `openflare-agent.service` systemd service on Linux + systemd. The service runs as the `openflare` unprivileged user, with Linux Capabilities (`CAP_NET_BIND_SERVICE`) enabling privileged ports (e.g. 80, 443).
+
+Supported parameters:
+
+| Parameter | Description |
+| --- | --- |
+| `--server-url` | Server address |
+| `--discovery-token` | first-time auto-registration Token |
+| `--agent-token` | node-specific Token |
+| `--install-dir` | install dir, default `/opt/openflare-agent` (local install only) |
+| `--openresty-path` | OpenResty binary path; auto-finds `openresty` when omitted (local install only) |
+| `--repo` | GitHub repo for downloading the Agent, default `Rain-kl/OpenFlare` |
+| `--no-service` | don't create the systemd service (local install only) |
+| `--docker` | install via Docker container |
+| `--method` | install method: `local` or `docker` (default `local`) |
+
+## Config File
+
+Default config file path:
+
+```text
+/opt/openflare-agent/agent.json
+```
+
+Local config example:
+
+```json
+{
+  "server_url": "http://127.0.0.1:3000",
+  "agent_token": "replace-with-node-auth-token",
+  "data_dir": "./data",
+  "openresty_path": "openresty",
+  "openresty_observability_port": 18081,
+  "observability_replay_minutes": 60,
+  "heartbeat_interval": 3000,
+  "request_timeout": 10000
+}
+```
+
+Custom OpenResty path example:
+
+```json
+{
+  "server_url": "http://127.0.0.1:3000",
+  "agent_token": "replace-with-node-auth-token",
+  "data_dir": "/var/lib/openflare-agent",
+  "openresty_path": "/usr/local/openresty/nginx/sbin/openresty",
+  "main_config_path": "/var/lib/openflare-agent/etc/nginx/nginx.conf",
+  "route_config_path": "/var/lib/openflare-agent/etc/nginx/conf.d/openflare_routes.conf",
+  "access_log_path": "/var/lib/openflare-agent/var/log/openflare/access.log",
+  "cert_dir": "/var/lib/openflare-agent/etc/nginx/certs",
+  "lua_dir": "/var/lib/openflare-agent/etc/nginx/lua",
+  "runtime_config_dir": "/var/lib/openflare-agent/etc/openflare",
+  "heartbeat_interval": 3000,
+  "request_timeout": 10000
+}
+```
+
+Without `openresty_path`, the Agent calls `openresty` by default. Full fields: [Configuration Reference](../reference/configuration.md#agent-命令行参数与配置字段).
+
+## Running with Docker
+
+For Docker deployment, directly run the Agent image with a built-in OpenResty:
+
+```bash
+docker pull ghcr.io/rain-kl/openflare-agent:latest
+docker rm -f openflare-agent 2>/dev/null || true
+docker run -d --name openflare-agent --restart unless-stopped \
+  -p 80:80 -p 443:443/tcp -p 443:443/udp \
+  -v openflare-agent-pages:/data/var/lib/openflare/pages \
+  -e OPENFLARE_SERVER_URL=http://your-server:3000 \
+  -e OPENFLARE_AGENT_TOKEN=YOUR_AGENT_TOKEN \
+  ghcr.io/rain-kl/openflare-agent:latest
+```
+
+> [!NOTE]
+> **Pages persistence**
+> By default the Pages deployment dir is mounted to the Docker named volume `openflare-agent-pages` (container path `/data/var/lib/openflare/pages`). Rebuilding or upgrading the Agent container doesn't require re-pulling static site packages.
+
+## Uninstall
+
+### Interactive Uninstall (recommended)
+
+Running the uninstall script without any arguments enters interactive mode with a menu choosing the method (local uninstall / Docker container uninstall):
+
+```bash
+curl -fsSL https://raw.githubusercontent.com/Rain-kl/OpenFlare/main/scripts/uninstall-agent.sh | bash
+```
+
+### Docker Container Uninstall
+
+Stop and remove the `openflare-agent` container.
+
+## FAQ
+
+| Symptom | Handling |
+| --- | --- |
+| `agent_token and discovery_token cannot both be empty` | check that `agent.json` has at least one Token |
+| Node stays offline | run `curl -I http://your-server:3000` on the Agent node to confirm the Server address is reachable |
+| Repeated failure after release | the Agent blocks re-applying the same `version + checksum`; click「Force Sync」in the node detail page, or republish a new version |

+# Deployment Guide
+
+You will learn: OpenFlare's recommended deployment approaches, Server and Agent runtime requirements, source startup, integration steps, and upgrade/uninstall entries.
+
+Production recommends PostgreSQL as the Server DB, with `APP_SESSION_SECRET` etc. configured via `config.yaml` or env vars. The full Docker Compose deployment requires Redis; ClickHouse is optional for massive access logs and observability time series (see the repo root `docker-compose.yaml`). The Agent supports both Docker deployment and a local install script; the Docker image bundles the OpenResty binary. Log-DB determination and switching: [Log Store Decoupling](../design/logstore.md).
+
+## Deployment Topology
+
+### Standard Reverse Proxy Traffic Path
+
+```text
+Browser
+  |
+  v
+OpenFlare Server :3000
+  |
+  | Agent API / heartbeat / config pull
+  v
+OpenFlare Agent
+  |
+  v
+OpenResty binary
+  |
+  v
+Origin service
+```
+
+### Intranet Penetration Traffic Path
+
+```text
+Browser
+  |
+  v
+OpenResty (Agent, WAF/HTTPS termination)      <-- TunnelRelay node
+  |
+  | proxy_pass (127.0.0.1:{vhost_port})
+  v
+OpenFlareRelay (frps process)                 <-- TunnelRelay node
+  |
+  | frp tunnel protocol
+  v
+OpenFlared (frpc client)                      <-- intranet server
+  |
+  v
+Internal Service (192.168.x.x)
+```
+
+## Prerequisites
+
+### Hardware Recommendations
+
+| Component | Reference (entry) | Reference (production) | Notes |
+| --- | --- | --- | --- |
+| **Server control plane** | 1 core / 2 GB RAM / 20 GB disk | 2 cores / 4 GB RAM / 50 GB+ disk | expand disk by access-log retention and concurrent traffic |
+| **Agent data plane** | 1 core / 512 MB RAM / 2 GB disk | 2 cores / 2 GB RAM / 10 GB+ disk | expand by OpenResty concurrent proxy connections and WAF interception |
+| **Relay node** | 1 core / 1 GB RAM / 5 GB disk | 2 cores / 2 GB RAM / 20 GB disk | frps relay throughput limited by bandwidth and CPU |
+| **OpenFlared client** | 1 core / 256 MB RAM / 1 GB disk | 1 core / 512 MB RAM / 5 GB disk | runs independently in the intranet, tiny footprint |
+
+## Docker Compose Server Deployment
+
+The repo root provides a full `docker-compose.yaml` (PostgreSQL, Redis, ClickHouse, Jaeger).
+
+```bash
+curl -o .env.example https://raw.githubusercontent.com/Rain-kl/OpenFlare/refs/heads/main/.env.example
+cp .env.example .env
+# edit .env; at minimum change APP_SESSION_SECRET and the DB passwords
+docker compose up -d
+docker compose ps
+docker compose logs -f openflare
+```
+
+First visit `http://localhost:3000`; default account `admin` / `12345678`. Change the default password immediately after login.
+
+## Source Startup
+
+First build the admin frontend:
+
+```bash
+cd frontend
+corepack enable
+pnpm install
+pnpm build:embed
+```
+
+Then start the Server (repo root):
+
+```bash
+cp config.example.yaml config.yaml
+export APP_SESSION_SECRET='replace-with-a-long-random-string'
+# optional: use PostgreSQL
+# export DB_HOST=127.0.0.1 DB_USERNAME=postgres DB_PASSWORD=postgres DB_NAME=openflare
+go run main.go all
+```
+
+Listens on `:3000` by default (controlled by `app.addr` in `config.yaml` or `APP_ADDR`).
+
+## Run the Agent with Docker (recommended)
+
+Docker is the recommended Agent deployment. The Agent image is built on the OpenResty image, bundling the Agent controller and the OpenResty binary. Without an explicit `node_ip`, the Agent prefers fetching the real egress IP via a third-party API, avoiding registering the Docker bridge address as the node IP.
+
+```bash
+docker pull ghcr.io/rain-kl/openflare-agent:latest
+docker rm -f openflare-agent 2>/dev/null || true
+docker run -d --name openflare-agent --restart unless-stopped \
+  -p 80:80 -p 443:443/tcp -p 443:443/udp \
+  -v openflare-agent-pages:/data/var/lib/openflare/pages \
+  -e OPENFLARE_SERVER_URL=http://your-server:3000 \
+  -e OPENFLARE_AGENT_TOKEN=YOUR_AGENT_TOKEN \
+  ghcr.io/rain-kl/openflare-agent:latest
+```
+
+The named volume `openflare-agent-pages` persists the Pages deployment dir; rebuilding the container doesn't require re-pulling static site packages.
+
+## Agent Access (script install)
+
+Besides Docker, the install script can deploy the Agent to the local host. The script registers the low-privilege `openflare` service account and runs the systemd service as that user, using Linux Capabilities to safely listen on privileged ports 80/443.
+
+Auto-register with `discovery_token`:
+
+```bash
+curl -fsSL https://raw.githubusercontent.com/Rain-kl/OpenFlare/main/scripts/install-agent.sh | bash -s -- \
+  --server-url http://your-server:3000 \
+  --discovery-token YOUR_DISCOVERY_TOKEN
+```
+
+With node-specific `agent_token`:
+
+```bash
+curl -fsSL https://raw.githubusercontent.com/Rain-kl/OpenFlare/main/scripts/install-agent.sh | bash -s -- \
+  --server-url http://your-server:3000 \
+  --agent-token YOUR_AGENT_TOKEN
+```
+
+Install script parameters:
+
+| Parameter | Description |
+| --- | --- |
+| `--server-url` | Server address, required |
+| `--discovery-token` | first-time auto-registration Token, one of two with `--agent-token` |
+| `--agent-token` | node-specific Token, one of two with `--discovery-token` |
+| `--install-dir` | install dir, default `/opt/openflare-agent` |
+| `--openresty-path` | OpenResty binary path; auto-finds `openresty` when omitted |
+| `--repo` | GitHub repo for downloading the Agent, default `Rain-kl/OpenFlare` |
+| `--no-service` | don't create the systemd service |
+
+Confirm state:
+
+```bash
+systemctl status openflare-agent
+journalctl -u openflare-agent -f

+# Deploy the OpenFlared Client
+
+You will learn: OpenFlared's responsibilities, config parameters and env vars, running the client with Docker, and deploying it standalone on an intranet server via binary.
+
+**OpenFlared** is the tunnel client deployed in your intranet (LAN, private cloud, or any environment not directly reachable from the public internet). Its core responsibility is communicating with the control plane (OpenFlare Server) via `X-Tunnel-Token`, and locally spawning and managing one or more **frpc (fast reverse proxy client)** processes to securely and stably tunnel intranet HTTP traffic to public relay nodes.
+
+---
+
+## Prerequisites
+
+1. **Get a Tunnel Token**: add a node of type **Tunnel** in admin「Node Management」, save it, then open the node detail page to view the dedicated access Token.
+2. **Outbound network access**: the intranet server needs no public inbound IP or port mapping, but must reach the public **OpenFlare Server address** and the corresponding **TunnelRelay node relay port (default 7000)** over the network.
+3. **Software dependency** (host deployment only):
+   - an executable `frpc` binary locally, or an explicitly specified path via parameter.
+
+---
+
+## Config File and Env Vars
+
+`openflared` reads `flared.json` in the current directory by default at startup, fully overridable via env vars.
+
+### Config Field Details
+
+| JSON field | Env var | Description | Default |
+| --- | --- | --- | --- |
+| `server_url` | `OPENFLARE_SERVER_URL` | OpenFlare Server API service address | **none (required)** |
+| `tunnel_token` | `OPENFLARE_TUNNEL_TOKEN` | tunnel client's dedicated auth Token | **none (required)** |
+| `frpc_path` | `OPENFLARE_FRPC_PATH` | frpc executable binary path | `"frpc"` |
+| `data_dir` | `OPENFLARE_DATA_DIR` | local data and generated `frpc_{relayNodeID}.toml` directory | `"./data"` |
+| `state_path` | - | local state record file path (last applied config version) | `"{data_dir}/flared-state.json"` |
+| `heartbeat_interval`| - | state heartbeat report period (ms int or Go Duration string) | `10000` (10s) |
+| `sync_interval` | - | tunnel config pull/sync period (ms int or Go Duration string) | `30000` (30s) |
+| `request_timeout` | - | API network request timeout | `10000` (10s) |
+
+---
+
+## Running with Docker
+
+Docker deployment is the simplest and safest way to run in the intranet. The official `openflared` image bundles the client controller and the `frpc v0.69.0` binary runtime — no extra environment needed.
+
+```bash
+docker pull ghcr.io/rain-kl/openflared:latest
+docker rm -f openflared 2>/dev/null || true
+
+docker run -d --name openflared --restart unless-stopped \
+  -e OPENFLARE_SERVER_URL=http://your-server:3000 \
+  -e OPENFLARE_TUNNEL_TOKEN=YOUR_TUNNEL_TOKEN \
+  -v openflared-data:/app/data \
+  ghcr.io/rain-kl/openflared:latest
+```
+
+---
+
+## Startup and Verification
+
+### 1. Auto-Sync Logic
+
+After starting successfully, OpenFlared runs this workflow:
+- **Heartbeat & config fetch**: periodically syncs with the Server's `/api/v1/tunnel/heartbeat` and `/api/v1/tunnel/config/active` endpoints, validating the Token and detecting config versions.
+- **File rendering**: when a config version (or checksum) changes, it auto-pulls the tunnel's full route rules. If multiple Relay nodes are bound, it renders `frpc_{relayNodeID}.toml` per Relay under `data_dir`.
+- **Config-change restart**: when config or checksum changes, it re-spawns the corresponding `frpc` child processes to keep traffic mappings current.
+- **Abnormal self-recovery**: if a local `frpc` tunnel process exits abnormally, the supervisor restarts it with exponential backoff (initial 1s, cap 60s).
+
+### 2. View Logs and Connection State
+
+```bash
+# Docker container logs
+docker logs -f openflared
+```
+
+If the process runs correctly, you'll see output like:
+```text
+flared config loaded ...
+detected frpc version v0.69.0
+flared process started
+applying new tunnel config {"version": "...", "checksum": "..."}
+frpc process missing, starting {"relay_id": "..."}
+```
+
+### 3. Confirm in the Admin Panel
+
+Open **「Node Management」** in the admin panel and enter the Tunnel node's detail page:
+- View the node online state and flared runtime state (WebSocket connected / running / offline).
+- View the current applied version and the latest apply record.

+# Deploy Relay (Tunnel Relay)
+
+You will learn: TunnelRelay node responsibilities, `openflare-relay` config items and env vars, running Relay with Docker, and building/deploying Relay manually from source.
+
+In OpenFlare's intranet penetration system, the **TunnelRelay node** plays a key role. Unlike regular edge nodes, besides running the traditional Agent (hosting OpenResty for HTTPS/WAF processing), it also runs the **Relay (frps tunnel manager)** service on the same machine, listening for tunnel connections from intranet clients (OpenFlared) and relaying traffic.
+
+---
+
+## Prerequisites
+
+Before deploying a TunnelRelay node, make sure:
+
+1. **Registered as a TunnelRelay-type node**: in OpenFlare admin「Node Management」, add a node of type `tunnel_relay` and get its dedicated `agent_token`, or use the global `discovery_token`.
+2. **Network ports**:
+   - `bindPort` (frpc connection port, default `7000`) must be reachable by public/intranet clients.
+   - `vhostHTTPPort` (HTTP Vhost port, default `8080`) must be free; the Agent exchanges traffic with frps on this port.
+3. **Software dependency** (host deployment only):
+   - an executable `frps` binary locally, or an explicitly specified path via parameter.
+
+---
+
+## Config File and Env Vars
+
+`openflare-relay` reads `relay.json` in the current directory by default at startup, fully overridable via env vars.
+
+### Config Field Details
+
+| JSON field | Env var | Description | Default |
+| --- | --- | --- | --- |
+| `server_url` | `OPENFLARE_SERVER_URL` | OpenFlare Server API service address | **none (required)** |
+| `agent_token` | `OPENFLARE_AGENT_TOKEN` | node-specific Token | one of these two |
+| `discovery_token` | `OPENFLARE_DISCOVERY_TOKEN` | auto-registration Token | one of these two |
+| `node_name` | `OPENFLARE_NODE_NAME` | node identifier name | local hostname by default |
+| `node_ip` | `OPENFLARE_NODE_IP` | node egress/listen IP | auto-detected real egress IP |
+| `frps_path` | `OPENFLARE_FRPS_PATH` | frps executable binary path | `"frps"` |
+| `data_dir` | `OPENFLARE_DATA_DIR` | local data and generated `frps.toml` directory | `"./data"` |
+| `state_path` | - | local state JSON record file path | `"{data_dir}/relay-state.json"` |
+| `heartbeat_interval`| - | heartbeat period (ms int or Go Duration string) | `10000` (10s) |
+| `request_timeout` | - | API request timeout | `10000` (10s) |
+
+---
+
+## Running with Docker
+
+Docker is the most convenient deployment for a TunnelRelay node. The official image bundles the `openflare-relay` controller and the `frps` runtime — out of the box.
+
+```bash
+docker pull ghcr.io/rain-kl/openflare-relay:latest
+docker rm -f openflare-relay 2>/dev/null || true
+
+docker run -d --name openflare-relay --restart unless-stopped \
+  -p 7000:7000 \
+  -p 17500:17500 \
+  -e OPENFLARE_SERVER_URL=http://your-server:3000 \
+  -e OPENFLARE_AGENT_TOKEN=YOUR_AGENT_TOKEN \
+  -v openflare-relay-data:/app/data \
+  ghcr.io/rain-kl/openflare-relay:latest
+```
+
+> [!TIP]
+> The `-p 7000:7000` mapping is the port frpc clients connect to for relaying. If the admin panel configures a custom `relay_bind_port`, adjust the host port mapping accordingly.
+
+> [!NOTE]
+> **Enable the embedded frps Web UI**:
+> If the Server control panel enables the relay traffic monitoring panel (i.e. `relay_frps_web_ui_enabled` set to `true` in DB/system settings), you need to map the Web port (default `17500`, controlled by `relay_frps_web_ui_port` in system settings) to the host via `-p 17500:17500`.
+> The Web UI username is fixed to `admin`, and the password is the relay node's `agent_token`.
+
+---
+
+## Startup and Verification
+
+### 1. View Process Logs
+
+```bash
+# Docker container logs
+docker logs -f openflare-relay
+```
+
+### 2. Verify Runtime State
+
+After starting successfully, the Relay will:
+- Send HTTP heartbeats to the control plane to register/go online.
+- Fetch the latest frps base config from the control plane (including `bindPort`, `vhostHTTPPort`, and the auto-generated tunnel auth credential `auth_token`).
+- Render the local `data/frps.toml` config file.
+- Spawn the child process `frps -c data/frps.toml`.
+- If the process exits unexpectedly, the Relay auto-restarts frps with exponential backoff (initial 1s, cap 60s).
+
+### 3. Confirm in the Admin Panel
+
+Log in to the admin panel, navigate to **「Node Management」**, and confirm:
+- The TunnelRelay node status is marked **「Online」**.
+- The node type is correctly marked as **Relay node** and the frps runtime state is **Healthy**.

+# Start the Server
+
+You will learn: how to deploy with Docker (quick start, production-recommended, advanced) and how to deploy the OpenFlare Server locally from source.
+
+The OpenFlare Server is a Gin + GORM monolithic control plane responsible for the admin UI, admin API, Agent API, config rendering, version release, data storage, and aggregation queries.
+
+> [!IMPORTANT]
+> **About external dependencies**:
+> OpenFlare has built-in support for background async tasks (Asynq framework). Therefore, **regardless of deployment mode, Redis (or Valkey) is required**. The main difference between deployment options is the primary relational DB choice (SQLite vs PostgreSQL) and whether tracing (Jaeger) is enabled.
+> For high business traffic, ClickHouse is recommended for log storage.
+
+> [!TIP]
+> **ClickHouse server performance config (recommended mount)**
+> The control plane is typically a small host (e.g. 3c6g). The `performance.xml` provided in the repo tightens the background merge/mutation thread pools, avoiding high idle CPU or ClickHouse 25.x startup validation failures on small machines.
+> Mount the local `./config/clickhouse/performance.xml` as a single file at `/etc/clickhouse-server/config.d/performance.xml` to keep the official image's built-in Docker network listening config.
+
+Pull the config locally before deploying:
+
+```bash
+mkdir -p ./config/clickhouse
+curl -fsSL -o ./config/clickhouse/performance.xml \
+  https://raw.githubusercontent.com/Rain-kl/OpenFlare/refs/heads/main/config/clickhouse/performance.xml
+```
+
+Add it to the ClickHouse service `volumes` (alongside the data volume):
+
+```yaml
+volumes:
+  - ./data/clickhouse_data:/var/lib/clickhouse   # or named volume
+  - ./config/clickhouse/performance.xml:/etc/clickhouse-server/config.d/performance.xml:ro
+```
+
+After modifying `performance.xml`, run `docker compose restart clickhouse` for it to take effect.
+
+---
+
+## Method 1: Docker Deployment (recommended)
+
+Docker deployment avoids configuring Go and Node.js frontend build environments locally. Choose one of the three options based on your hardware and needs:
+
+### 1. Quick Start (SQLite + Redis)
+
+> **Use case**: testing/experience, lightweight single-machine deployment.
+>
+> **Features**: primary relational DB is SQLite.
+
+Create a `docker-compose.yaml`:
+
+```yaml
+version: '3.8'
+
+services:
+  openflare:
+    image: ghcr.io/rain-kl/openflare:latest
+    container_name: openflare-server
+    restart: unless-stopped
+    ports:
+      - "3000:3000"
+    volumes:
+      - ./openflare-data:/data
+      - ./uploads:/app/uploads
+    environment:
+      TZ: Asia/Shanghai
+      APP_SESSION_SECRET: 'replace-with-a-long-random-string' # replace with a long random string in production
+      DB_ENABLED: "false" # disables PostgreSQL, auto-enables the built-in SQLite fallback
+      SQLITE_PATH: "/data/openflare.db"
+      REDIS_ENABLED: "true"
+      REDIS_ADDR: "redis:6379"
+    depends_on:
+      redis:
+        condition: service_healthy
+
+  redis:
+    image: valkey/valkey:8.0-alpine
+    restart: unless-stopped
+    command: ["valkey-server", "--appendonly", "yes"]
+    volumes:
+      - ./data/valkey:/data
+    healthcheck:
+      test: ["CMD", "valkey-cli", "ping"]
+      interval: 10s
+      timeout: 5s
+      retries: 5
+```
+
+---
+
+### 2. Small-Traffic Business (PostgreSQL + Redis)
+
+> **Use case**: production, small-to-medium traffic; PostgreSQL won't be the log-write bottleneck.
+
+Create a `docker-compose.yaml`:
+
+```yaml
+services:
+  openflare:
+    image: ghcr.io/rain-kl/openflare:latest
+    restart: unless-stopped
+    env_file: .env
+    environment:
+      TZ: ${TZ:-Asia/Shanghai}
+    ports:
+      - "3000:3000"
+    volumes:
+      - openflare_uploads:/app/uploads
+    depends_on:
+      postgres:

+      interval: 10s
+      timeout: 5s
+      retries: 5
+      start_period: 5s
+
+volumes:
+    openflare_uploads:
+    openflare_postgres_data:
+    openflare_redis_data:
+```
+
+Create a matching `.env` file for system env vars (copy and modify the root `.env.example`):
+
+```bash
+curl -o .env.example https://raw.githubusercontent.com/Rain-kl/OpenFlare/refs/heads/main/.env.example
+cp .env.example .env
+# edit .env: fill in DB, Redis, passwords, and APP_SESSION_SECRET
+
+docker compose up -d
+```
+
+---
+
+### 3. Advanced (full orchestration with Jaeger tracing)
+
+> **Use case**: high traffic; needs trace performance metrics.
+>
+> **Features**: on top of the "production-recommended" bundle, stores logs with ClickHouse and uses Jaeger as the OpenTelemetry (OTel) tracing backend.
+
+Create a `docker-compose.yaml`:
+

+| Username | Password |
+| --- | --- |
+| `admin` | `12345678` |
+
+> [!WARNING]
+> For your system's security, change the default password immediately in your profile settings after the first login.

+---
+
+## Distributed Deployment
+
+In large production deployments, split the Server into multiple processes by responsibility:
+
+```bash
+go run main.go api             # API service for admin panel and node communication only
+go run main.go worker          # background task Worker service only

+# Upgrade & Maintenance
+
+You will learn: how to upgrade the Server and Agent, how to clean up observability data, and which verification commands to run before and after maintenance.
+
+Before upgrading, confirm the current active version, the most recent Agent apply result, and the DB backup policy. In production, don't upgrade while a config release, a large-scale Agent reconnect, or a DB migration is in progress.
+
+## Server Upgrade
+
+Pull the latest image and upgrade:
+
+```bash
+docker compose pull
+docker compose up
+```
+
+For source deployments, restart the Server and confirm the logs show no DB migration or startup errors.
+
+## Agent Upgrade
+
+The Agent only caches runtime config and state files locally — no business data. To upgrade, directly pull the latest image and recreate the container. For specific deployment commands and install methods, see **[Access Agent](./agent.md)**.

+# Agent Design
+
+You will learn: the Agent's design principles, core functional modules, interaction chain with the Server, and how the immutable version model and three-stage disaster recovery guarantee config-apply safety and reliability.
+
+---
+
+## Requirements Analysis
+
+In distributed reverse-proxy and edge-security gateway scenarios, the Agent is the core bridge between the control plane (Server) and the data plane (OpenResty). Since the Agent runs on the user's actual node server, its design must satisfy these core security and HA requirements:
+
+1. **Active pull (Pull model), not passive receive**: the Server doesn't hold node SSH keys and never initiates inbound connections to nodes. All control instructions and config updates are pulled upward by the Agent via heartbeat or WebSocket. This removes inbound-firewall security risks on nodes and prevents control-channel hijacking.
+2. **Minimal invasiveness**: the Agent runs as a standalone Go binary, interacting with the local OpenResty process only via file-based config rewriting and signal notifications — no interference with other system services on the node.
+3. **Strong disaster recovery and self-healing**: since network jitter, full disks, or bad configs can easily break config sync, the Agent must have zero-dependency local rollback self-healing to prevent one bad config from taking down the whole machine.
+4. **Pure data and state landing**: the Agent only carries Server-rendered files and control intent to landing; it contains no complex business validation or multi-tenant auth — control-plane duties stay on the Server, keeping the node efficient and light.
+
+---
+
+## Core Features
+
+The Agent mainly consists of these submodules cooperating for its full lifecycle:
+
+| Module | Directory | Responsibility |
+| :--- | :--- | :--- |
+| **Config sync** | `sync/` | pull full config packages, write files, trigger reloads, record and report sync state. |
+| **Heartbeat** | `heartbeat/` | periodically report node health, resource metrics, and fetch the latest active version summary. |
+| **WebSocket** | `wsclient/` | keep a long connection to the Server for second-level real-time config push and control-plane instructions. |
+| **OpenResty control** | `nginx/` | run Nginx config validation (`openresty -t`), rewriting, smooth reload, and process auto-start. |
+| **Local state** | `state/` | persist local applied version, error logs, and buffered observability metrics not yet reported. |
+| **Self-update** | `updater/` | listen for Server self-update instructions, safely fetch new binaries, and hot-upgrade in place. |
+| **Observability** | `observability/` | collect host resource readings, OpenResty health/connections, and tail access-log details for reporting; **no** business pre-aggregation like UV/TopN/throughput. See [Edge Observability & Business Traffic Stats](./observability-design.md). |
+| **GeoIP maintenance** | `geoipdata/` `geoipupdate/` | maintain and periodically update the local GeoIP DB for WAF geo filtering. |
+
+---
+
+## Interaction Chain with the Server
+
+The Agent communicates with the control plane via **Token-based auto-registration** and **heartbeat/WebSocket dual channels** over its lifecycle.
+
+### 1. Auto-Registration Flow
+If `access_token` in the local `agent.json` is empty at startup but `discovery_token` is configured, auto-registration triggers:
+1. The Agent sends a registration request to `/api/v1/agent/nodes/register` with local hardware summary, IP, and hostname.
+2. The Server validates the `discovery_token`, generates a unique `NodeID` and dedicated `AccessToken` (i.e. `agent_token`), and returns them.
+3. The Agent writes the dedicated Token into the local config file, erases the one-time `discovery_token`, and all future communication authenticates with the dedicated `AccessToken`.
+
+### 2. Dual-Channel Heartbeat and Sync
+* **HTTP polling channel (fallback & probe)**: the Agent POSTs heartbeats at the configured `heartbeat_interval` by default, reporting metrics while fetching the current active version summary (Version & Checksum).
+* **WebSocket channel (real-time)**: after a successful HTTP heartbeat, the Agent auto-upgrades to WebSocket (`/api/v1/agent/ws`).
+  * Once established, heartbeat and metric reporting fully move to the WS pipe, reducing network overhead.
+  * When the Server releases/activates a new version, it broadcasts to Agents via WS. The Agent triggers sync **immediately** on the change event for second-level config effect.
+  * If the WS link drops due to network issues, the Agent degrades to HTTP polling and retries WS with exponential backoff.

+
+## OpenResty Control
+
+The Agent's control over the data-plane OpenResty forms an end-to-end loop: config landing, syntax validation, smooth reload, and abnormal-state capture.
+
+### 1. Config File Landing Organization
+After a successful sync, the Agent writes config under `data_dir` (default relative `etc/nginx/`, `etc/openflare/`, `var/lib/openflare/`; exact paths follow `main_config_path`, `route_config_path`, `cert_dir`, `lua_dir`, `runtime_config_dir`, `pages_dir` in `agent.json`):
+* `nginx.conf`: the main config (replaces relevant placeholders, configures performance params, Shared Dictionaries, and the global Server).
+* `conf.d/openflare_routes.conf`: the route config (generated by the Agent; contains all proxied sites' Server blocks, cert paths, cache, and rate-limit directives).
+* `certs/`: certificate dir (files named `{cert_id}.crt` and `{cert_id}.key`).
+* `lua/waf/` and `lua/pow/`: dedicated Lua runtime scripts for WAF and anti-CC challenges.
+* `etc/openflare/waf_config.json` and `waf_ip_groups.json`: structured rule configs for the WAF filtering engine.
+* `pages_dir`: the Pages static site deployment dir, default `data_dir/var/lib/openflare/pages`. When the active config references a Pages **project**, the Agent requests the control plane's「latest active package」(hash + package) by `project_id`, streams to a temp file with real response-size limits and SHA-256 validation, then safely extracts to `projects/{project_id}/releases/{hash}`. After extraction it rechecks file count and total bytes; absolute hard caps are 2 GiB package, 1,000 files, 8 GiB single-file/total. It then atomically switches `current` and **immediately deletes other historical releases of the same project** (only latest kept). Switching the active deployment within a project doesn't require republishing the main config; multi-project reconciliation isolates single-project failures.
+
+### 2. Fine-Grained Reload Actions
+1. **Back up current config**: before writing new files, copy existing config to a `.backup` temp dir, keeping a full scene snapshot.
+2. **Write and replace placeholders**: write the latest template, replacing absolute-path placeholders (e.g. `__OPENFLARE_LUA_DIR__`, `__OPENFLARE_PAGES_DIR__`) with local actual runtime paths.
+3. **Syntax validation**: run `openresty -t -c <temp_nginx.conf>` for strict syntax testing.
+4. **Smooth reload**: on validation pass, move the new config to the formal path and run `openresty -s reload`. If OpenResty isn't started, start the process with the current config.
+5. **Capture exceptions**: on validation/reload failure, the Agent captures command stdout/stderr as failure details for reporting.
+
+---
+
+## Release and Config Apply Model
+
+OpenFlare uses an **immutable config version release model**, not online dynamic patching of node configs.
+
+```text
+modify rules -> preview / view diff -> release -> generate full config version -> activate version -> Agent pulls -> local apply -> report result
+```
+
+### 1. Core Design Principles
+* **Full release**: each release compiles all enabled routes, certs, Pages deployment references, and global/local WAF rules on the control plane in one pass, generating a full version with a unique `checksum`.
+* **Version format**: `YYYYMMDD-NNN` incrementing format for intuitive, monotonically increasing version history.
+* **Globally single active version**: only one globally active config version exists at a time. Rollback doesn't reverse-patch; just set a historical healthy version to `active`, and Agents re-pull and apply it.
+
+### 2. Three-Stage Disaster Recovery Rollback
+When the Agent detects a config apply (or smooth reload) failure, it auto-activates this three-stage anti-outage chain:
+
+```mermaid
+graph TD
+    A[config apply failed] --> B[stage 1: try local backup restore]
+    B -- backup file exists --> C[write local backup files]
+    C --> D[run openresty -t validation]
+    D -- validation ok --> E[reload to restore old version]
+    D -- validation failed --> F[enter stage 2]
+    B -- no backup --> F[stage 2: write built-in safe fallback config]
+    F --> G[write fallback nginx.conf: listen on 80 only]
+    G --> H[enable stub_status health check]
+    G --> I[other routes return 503 uniformly and block bad configs]
+    G --> J[try starting OpenResty to keep basic liveness]
+    J --> K[enter stage 3]
+    E --> L[report Apply Warning]
+    K --> M[locally block re-applying the bad version]
+    M --> N[report Apply Error with detailed error]
+```
+
+1. **Stage 1: local backup fallback**
+   * The Agent tries restoring the main config, routes, and certs from the previously saved `.backup` dir.
+   * After writing backup files, re-run `openresty -t`. On success, reload back and report `Warning` to the Server (new version apply failed; auto-rolled back to the last healthy version).
+2. **Stage 2: built-in safe fallback runtime**
+   * If no local backup config exists (e.g. first deployment with a bad config), or the restored backup still fails validation, the Agent activates the final self-healing mechanism — writing the **built-in safe fallback config**.
+   * **Safe fallback spec**:
+     * listens only on port `80`, containing no user real reverse proxy routes.
+     * Everything except the `/openflare/stub_status` health-check route (which returns normally) returns `503 Service Unavailable` with a fixed body `OpenFlare: No Valid Configuration`.
+     * Tries starting OpenResty with this minimal config. This keeps the Nginx process itself alive, preserves the underlying health check/probe channel, prevents container/Pod restart loops from failed health checks, and protects sensitive routes.
+3. **Stage 3: local config blocking**
+   * The Agent records the crash-causing config `version + checksum` in a blocklist in the local state store.
+   * Until the control plane activates a new config (`checksum` changes), the Agent heartbeat blocks re-pulling that bad version — preventing the "heartbeat → pull crash config → crash rollback" infinite loop.
+
+### 3. WAF IP Group Runtime Async Sync
+To avoid high-frequency malicious-IP blocklist changes constantly triggering full main-config releases and reloads (smooth reload still has slight CPU and connection overhead on Nginx), IP group members use an **async differential sync** decoupled from release versions:
+
+* **Static release snapshot**: the released `waf_config.json` only contains rule groups' references to IP groups (`ip_whitelist_group_ids` / `ip_blacklist_group_ids`), not the concrete IP member lists.
+* **Heartbeat differential comparison**: the Agent reports the MD5 Checksum map of locally cached IP groups in heartbeat packets.
+* **Differential dispatch**: the Server compares the hashes of IP groups referenced by the current active version and only dispatches missing or changed members, written to the local `waf_ip_groups.json` for fast differential sync.
+* **WebSocket real-time notification**: when the Server manually updates an IP group, a subscription source sync succeeds, or security rules auto-trigger temporary bans, the Server immediately broadcasts the affected IP group update via WebSocket; the Agent lands it instantly — **no Nginx reload** throughout.
+
+---
+
+## Design Constraints
+
+To guarantee the security boundary of data and control channels, Agent code and secondary development must strictly follow:
+
+1. **Zero privileged command channel**: the Server is absolutely forbidden from passing arbitrary shell commands or remote script execution (exec/eval, etc.) to the Agent. All system control primitives (start, stop, reload, update) must be hardcoded inside the Agent binary.
+2. **Strict Token filtering and prefix validation**: when the Agent requests resources from the Server, endpoints are fixed under the `/api/v1/agent/` prefix and must carry `X-Agent-Token` for signature/token verification.
+3. **Node autonomy**: the Agent must have complete offline capability. While disconnected from the Server, the local OpenResty must keep reverse-proxying normally based on locally landed config.
+4. **Observability reports facts only**: access logs are reported as details; host metrics report counters/instant readings. Computing conclusion metrics like business UV, Top domains, or 24h data provided inside the Agent is forbidden (the Server aggregates). See [Edge Observability & Business Traffic Stats](./observability-design.md).
+5. **Pages consumes only control-plane artifacts**: Remote URLs, GitHub Releases, the auto scanner, and future repo checkout/build executors are all Server responsibilities. The Agent receives no external URLs, access tokens, repo credentials, or clone/install/build commands — it only pulls already-activated deployment packages with integrity metadata.

+# System Architecture
+
+You will learn: OpenFlare's overall architecture, the responsibility split of each core component (Server, Agent, OpenResty, Relay, Client), and the macro flow of the main data and request streams.
+
+OpenFlare is a self-hosted OpenResty control plane. Physically it consists of the Server (control plane), the Agent (config landing), node-local OpenResty (data plane), intranet penetration components (Relay and OpenFlared, data-plane extensions), and the admin frontend.
+
+---
+
+## Traffic Path Overview
+
+Depending on the website upstream type, OpenFlare supports three data-plane traffic paths:
+
+### 1. Standard Reverse Proxy Path
+```text
+Browser
+  |
+  | HTTPS/HTTP request
+  v
+OpenResty (WAF, TLS, Rate Limit, optional origin error page)
+  |
+  | reverse proxy (proxy_pass)
+  v
+Origin Server (direct public/LAN upstream)
+```
+
+When the origin or gateway returns an error status in the configured list, a global custom/default HTML can be returned while keeping the real HTTP status; see [Origin Error Page Design](./origin-error-page.md).
+
+### 2. Intranet Penetration Path
+For origin services on firewall-restricted intranet servers:
+```text
+Browser
+  |
+  | HTTPS/HTTP request
+  v
+OpenResty (Agent host, TLS/WAF)
+  |
+  | proxy_pass http://localhost:vhost_port (Host header preserved)
+  v
+OpenFlareRelay (frps)              <-- same host as the Agent, provides relaying
+  |
+  | frp tunnel protocol (Host header routing)
+  v
+OpenFlared (frpc)                  <-- firewall-restricted intranet server
+  |
+  | HTTP/HTTPS forward
+  v
+Internal Service (192.168.x.x)
+```
+
+### 3. Pages Static Hosting Path
+For pre-built SPAs or static site hosting:
+```text
+Browser
+  |
+  | HTTPS/HTTP request
+  v
+OpenResty (Agent, TLS/WAF)
+  |
+  +---> [static serving] root/try_files ---> Agent local Pages deployment dir
+  |
+  +---> [API proxy] proxy_pass ---> backend API service (if API proxying enabled)
+```
+
+---
+
+## Component Responsibilities
+
+| Component | Responsibility | Detailed Design Reference |
+| --- | --- | --- |
+| **Server** | admin UI/API, control-plane state persistence, config compilation/rendering, release versioning, Pages deployment package storage, Cloudflare A-record pointing, access-log storage and business traffic aggregation, Uptime Kuma monitoring sync, login CAPTCHA protection | [Agent & Publish Model](./agent-design.md) / [Cloudflare DNS Pointing Design](./cloudflare-pointing.md) / [Edge Observability & Business Traffic Stats](./observability-design.md) / [Uptime Kuma Sync Design](./kuma-design.md) / [Login CAPTCHA Design](./login-captcha.md) |
+| **Agent** | periodic heartbeat & WS sync, static package pull/extraction, OpenResty config write/validate/reload and self-healing; observability reports only access details and host/health readings, no business pre-aggregation | [Agent & Publish Model](./agent-design.md) / [Edge Observability & Business Traffic Stats](./observability-design.md) |
+| **OpenResty** | receives real traffic; executes WAF filtering, PoW protection, Basic Auth, static/reverse-proxy serving, and optional origin error pages | [WAF Design](./waf-design.md) / [Pages Design](./pages-design.md) / [Origin Error Page Design](./origin-error-page.md) |
+| **Relay** | deployed on edge nodes; manages the `frps` daemon lifecycle and accepts heartbeat-dispatched penetration relay configs | [Tunnel Design](./tunnel-design.md) |
+| **OpenFlared** | deployed in the intranet; manages the `frpc` process group, establishes reverse tunnels to multiple Relays, reports connection state | [Tunnel Design](./tunnel-design.md) |
+
+---
+
+## Component Architecture and Division
+
+### 1. Server (control plane)
+The Go backend at the repo root (module `github.com/Rain-kl/Wavelet`) is the OpenFlare control plane, built on the Wavelet full-stack scaffold:
+* Provides admin REST APIs (`/api/v1/d/*`) authenticated via **Session Cookie**, with optional `X-Access-Token`.
+* Edge node protocols go through `/api/v1/agent|relay|tunnel/*`, authenticated with `X-Agent-Token` / `X-Tunnel-Token` respectively.
+* Contains the config Compiler, uniformly compiling DB rules, certs, and global params into immutable config snapshots and OpenResty physical config file text.
+* Uniformly receives Pages local uploads, Remote URLs, and public GitHub Release pre-built artifacts, completing source checks, restricted downloads, archive validation, and immutable deployments; manual uploads create candidates awaiting explicit activation, persistent-source sync creates-or-loads and atomically activates. The Server offers controlled latest-download endpoints to Agents; the internal scanner handles limited GitHub latest checks, lease recovery, optional auto-publish, and orphan upload compensation; the generic task management entry can't modify this schedule. Future repo source builds are extended by a standalone Server build executor; the Agent never executes third-party fetch or build commands.
+* Provides the optional Cloudflare DNS pointing control plane: maintains group desired state with ZoneDomains as members, idempotently syncing a single A record to the current active node IPv4 via Asynq; node IP changes only best-effort enqueue; no auto-failover in phase 1.
+* Backend integration with the Uptime Kuma monitoring sync service auto-maintains HTTP probe tasks for available sites.
+* Startup entry: root `main.go` + `internal/cmd/` (`api` / `worker` / `scheduler` / `all`); OpenFlare business in `internal/apps/openflare/`, edge protocol handling in `internal/apps/openflare/{agent,relay,flared}/`.
+* *See: [Agent & Publish Model](./agent-design.md) and [Uptime Kuma Sync Design](./kuma-design.md)*
+
+### 2. Agent (config landing)
+`openflare-agent` is the daemon running on the node:
+* Maintains periodic heartbeats with the control plane after startup, receiving real-time config release broadcasts via the optional WebSocket.
+* Pulls the latest active version's config files and certs, writes them locally, and performs safe validation via `openresty -t` before a smooth reload.
+* Handles Pages deployment package download, SHA-256 validation, and extraction switching locally.
+* *See: [Agent & Publish Model](./agent-design.md)*
+
+### 3. OpenResty (data plane)
+Receives visitor traffic and performs final business landing:
+* Traffic entry, supporting HTTP/2, HTTP/3 (QUIC), and dynamic TLS certificate binding.
+* Embeds Lua logic filtering WAF rules and verifying PoW challenges efficiently in the `access_by_lua` phase, followed by connection/rate limits and basic caching (policy in [Edge Cache Strategy Design](./edge-cache-design.md)).
+* *See: [WAF Design](./waf-design.md) and [Pages Static Hosting Design](./pages-design.md)*
+
+### 4. Relay and OpenFlared (tunnel components)
+Extend data-plane reverse penetration:
+* `openflare-relay` guards the local `frps`, accepts Server config dispatch, and auto-updates the relay port.
+* `openflared` guards a group of `frpc` client processes in the intranet for nearest multi-relay connections and HA disaster recovery.
+* *See: [Tunnel Design](./tunnel-design.md)*
+
+---
+
+## Data and Request Flow Overview
+
+### 1. Config Release and Sync Flow
+```text
+admin modifies config -> release new version -> generate globally unique Checksum active version
+                                 |
+              +------------------+------------------+

+  report apply state (Success / Error)          report tunnel connection state and metrics
+```
+* *Fine-grained sync/self-healing timing and the rollback model: [Agent & Publish Model](./agent-design.md)*
+
+### 2. Static Hosting and API Proxy Flow
+* Static assets are extracted to `projects/{project_id}/current` on the Agent node (pulled per project latest, only the newest package kept); OpenResty serves static resources at the edge via `root`/`index`/`try_files`.
+* With API proxying enabled, OpenResty rewrites and forwards (`proxy_pass`) API requests to the backend dynamic API based on the site's `api_proxy_path` (e.g. `/api`).
+* Admin operations and the internal scanner only generate constrained artifact candidates, reusing the unified inspect, `upload.Ingest`, and deployment pipeline. Manual uploads create a new inactive candidate; persistent-source sync/scanner creates-or-loads and atomically activates. A future repository build executor can only emit into the same artifact pipeline; the Agent is always just an active-deployment consumer.
+* *Package validation, extraction escape defense, and Nginx rule rendering: [Pages Static Hosting Design](./pages-design.md)*
+
+### 3. WAF Security Filtering Flow
+* The WAF engine is embedded in the OpenResty request lifecycle.
+* WAF rules are orchestrated as a visual DAG on the control plane and compiled into a runtime graph at release; after an OpenResty reload each Worker loads it once, and subsequent requests only traverse the in-memory object.
+* Global rules always run first; route-bound rules execute in explicit order; reaching "pass" in the current rule continues to the next, reaching "block" immediately returns that node's configured block response.
+* IP group members hot-update independently: a coordinating worker checks the checksum every 5 seconds, loading the full snapshot only on change; each Worker's request path always reads the local in-memory object.
+* *IP group sources and sync: [WAF Design](./waf-design.md); graph model, execution semantics, release constraints: [WAF Orchestration Rule Design](./waf-orchestration-design.md)*
+
+### 4. Edge Observability and Business Traffic Stats Flow
+```text
+OpenResty access.log (business facts)
+        |
+        | Agent tails incremental details (no sum/count/uniq)
+        v
+Server stores via logstore (current log primary DB: PostgreSQL / SQLite / ClickHouse)
+        |
+        +---> global aggregation --> dashboard "data provided / requests / UV"
+        +---> host∈Zone --> Zone "data provided" etc. (same semantics)
+        +---> node_id filter --> node business volume
+
+host /proc NIC, CPU etc. --> Agent reading snapshots --> host resource trends (displayed separately from business delivery)
+OpenResty health and connections --> edge health (instant, not 24h business totals)
+```
+* **Principle**: the Agent reports only facts; the Server interprets facts; access logs are the single truth for business traffic. `openresty_tx` and "data provided" must not run on dual tracks.
+* *Transport model, examples, and collection frequency: [Observability Transport Model](./observability-transport-model.md); field convergence and migration: [Edge Observability & Business Traffic Stats](./observability-design.md)*
+
+### 5. Cloudflare DNS Pointing Flow
+
+```text
+admin configures connection/group/member -> Server persists desired state -> Asynq sync tasks

+                                    single A record -> active_node IPv4
+
+node IP manually updated or Agent heartbeat change --------------------> best-effort enqueue per node
+```
+
+* The Cloudflare module only manages cached or taken-over uniquely-named A records; it doesn't extend the Zone core into an authoritative DNS control plane. On multiple same-name A records it stops syncing and asks the admin to clean up in Cloudflare.
+* Group backup/active nodes are reserved for later failover; phase 1 fixes the primary node and doesn't auto-switch on heartbeat offline.
+* *Connection, model, idempotent sync, and phasing: [Cloudflare DNS Pointing Design](./cloudflare-pointing.md)*
+

+
+## Core Objects
+
+Current core system entities include:
+
+* **Reverse proxy & config**: `zones` (root-domain management boundary), `zone_domains` (explicit domains with cert/route association), `proxy_routes` (route policy), `origins`, `config_versions`, `tls_certificates`. See [Zone & Domain Resource Design](./zone-design.md).
+* **Cloudflare DNS pointing**: `of_cf_connections` (global connection), `of_cf_pointing_groups` (primary/backup/active nodes and default orange-cloud), `of_cf_pointing_members` (ZoneDomain members, record cache, sync state). See [Cloudflare DNS Pointing Design](./cloudflare-pointing.md).
+* **Pages static hosting**: `of_pages_projects`, `of_pages_project_sources` / `of_pages_project_source_runtime` (mutable source config and runtime), `of_pages_deployments` (immutable deployments), `of_pages_deployment_files` (deployment file manifests).
+* **Nodes & tunnels**: `nodes`, `tunnels` (tunnel clients), `node_system_profiles`, `apply_logs`.
+* **WAF & security**: `waf_rule_groups`, `waf_ip_groups`, `waf_rule_group_bindings` (site WAF bindings).
+* **System & accounts**: `acme_accounts`, `dns_accounts`, `geoip_update_configs`.

+## Key Design Decisions
+
+| Decision | Reason |
+| --- | --- |
+| Full config versions instead of online patching | stable boundaries for preview, activation, history, and rollback; consistent node state |
+| Agent active pull | the Server needs no SSH access, lowering security risk; supports HTTP/WebSocket dual-protocol switching |
+| Globally single active version | lowers control-plane complexity, keeps all nodes consistent by default; stable one-click second-level rollback |
+| Zone domains separated from route policy | Zones provide the root-domain entry and domain boundaries; routes still reuse the same site-level policy and bind certs per domain |
+| Cloudflare pointing independent of the Zone core | ZoneDomains only provide explicit FQDNs; the Cloudflare module drives single A records from DB desired state without widening Zones into a general DNS control plane |
+| Intranet penetration integrated on frp | reuses a mature tunnel protocol, avoiding self-built tunnel stability risks; its Vhost mechanism natively fits reverse-proxy routes |
+| Runtime config decoupled from the control store | WAF rules compile at release and load with the OpenResty reload; dynamic IP groups refresh independently via checksum-driven memory snapshots |
+| Access logs as the single truth for business traffic | the Agent forbids business pre-aggregation; dashboard and Zone share Server-side aggregation, avoiding openresty_tx vs bytes_sent dual tracks |
+| Business delivery / edge health / host capacity layered | data provided ≠ host NIC outbound ≠ OpenResty connections; UI and API name and section them separately |
+| Pages artifacts separated from repo builds | current sources only import pre-built artifacts; future checkout/build happens in a Server-isolated executor reusing the artifact pipeline; the Agent never runs third-party builds |

+# Cloudflare DNS Pointing Design
+
+## Goals
+
+Point **ZoneDomains (explicit FQDNs)** in OpenFlare to edge node IPs quickly via the Cloudflare API, replacing manual A-record edits in the CF console. Users organize domains into **pointing groups**: each group configures a primary node, a backup node, and a default orange-cloud (proxied) policy; members can override orange-cloud individually. The system treats the database tables as the desired state and idempotently syncs remote DNS.
+
+This module is an **optional integration capability**; it does not turn Zones into an authoritative DNS control plane. Zones still only handle root-domain boundaries, domains, certificates, and reverse-proxy associations; A record create/update/delete is driven by this module through Cloudflare.
+
+## Scope and Phasing
+
+### Phase 1 (this design's scope)
+
+* Sidebar **Cloudflare** entry with a Token-ready gate
+* Connection config: import from an existing DNS account **or** standalone entry within the module (mixed sources), stored encrypted
+* Pointing group CRUD: primary node, backup node (reserved), group default orange-cloud
+* Member management: add/remove at the granularity of `zone_domain_id`; member-level orange-cloud
+* Sync: write each member as a **single A record** on Cloudflare → current active node IPv4
+* Triggers: manual sync, member add, node/orange-cloud change, node IP change enqueue
+* Async task batch sync; member sync status with readable errors
+
+### Phase 2
+
+* Agent heartbeat offline detection of primary node failure → `active_node` switches to backup → whole-group auto sync
+* Optional auto failback, failure notification push
+
+### Explicitly Out of Scope (later or permanent)
+
+* Multiple parallel Cloudflare accounts (one global connection config)
+* AAAA / multi-A load balancing / CNAME to node hostnames
+* Managing MX/TXT/Page Rules and other non-module A records
+* Non-Cloudflare DNS providers
+* Merging DNS record management into the Zone core model
+
+## Relationship with Existing Capabilities
+
+| Existing Capability | Relationship |
+| --- | --- |
+| `of_zones` / `of_zone_domains` | Provide the pointable FQDN list; this module only references `zone_domain_id` |
+| `of_nodes.ip` | Source of A record `content`; recommended to restrict to edge nodes with valid IPv4 |
+| `of_dns_accounts` + `sealSensitive` | ACME DNS-01 already supports Cloudflare Token; this module can **import** the same account or store a Token standalone |
+| lego Cloudflare provider | **Only** TXT/DNS-01; this module builds its own CF HTTP client for Zone/DNS Record APIs |

+
+### `of_cf_connections` (one valid connection globally)
+
+| Field | Description |
+| --- | --- |
+| `source` | `dns_account` \| `standalone` |
+| `dns_account_id` | references `of_dns_accounts` (type=cloudflare) when `source=dns_account` |
+| `authorization` | encrypted storage when `source=standalone`, payload shape `{"api_token":"..."}`, consistent with DNS accounts; the API **never returns it** |
+| `status` / `verified_at` | connectivity check result and time |
+
+**Token resolution:** `dns_account` → decrypt the associated account; `standalone` → decrypt this row. Associated account deleted or validation failed → module not ready, sync forbidden.
+
+**Recommended permissions:** Cloudflare API Token with `Zone:Read`, `DNS:Edit`.
+
+### `of_cf_pointing_groups`
+
+| Field | Description |
+| --- | --- |
+| `name` | display name |
+| `primary_node_id` | primary node |
+| `backup_node_id` | backup (nullable; phase 1 stores only) |
+| `active_node_id` | currently effective node; equals primary in phase 1; rewritten by phase 2 failover |
+| `default_proxied` | group default orange-cloud; **only affects newly added members** |
+| `enabled` | whether to participate in sync |
+
+Constraints: primary and backup must not be the same node; the node chosen as the active target must have a valid IPv4.
+
+### `of_cf_pointing_members`
+
+| Field | Description |
+| --- | --- |
+| `group_id` | owning group |
+| `zone_domain_id` | globally unique: one domain belongs to at most one group |
+| `proxied` | member orange-cloud (the only runtime basis) |
+| `cf_zone_id` / `cf_record_id` | Cloudflare cache for idempotent updates |
+| `desired_ip` / `sync_status` / `last_error` / `synced_at` | desired and sync state |
+
+`sync_status`: `pending` \| `syncing` \| `ok` \| `error`.
+
+No physical foreign keys; `zone_domain_id` unique index; query indexes on `group_id` etc.
+
+## Orange-Cloud Priority
+
+1. **Member `proxied`**: the only basis written to CF during sync.
+2. **Group `default_proxied`**: copied to `proxied` when a member is **added**.
+3. Later changes to the group default **do not rewrite** existing members.
+
+## Sync Semantics
+
+### Desired State
+
+The OpenFlare DB tables are the Source of Truth. Each member expects:
+
+| Item | Value |
+| --- | --- |
+| type | `A` |
+| name | the ZoneDomain's FQDN |
+| content | the group `active_node`'s IPv4 |
+| proxied | member `proxied` |
+| ttl | forced Auto by CF when orange-cloud is on; unified default (e.g. 300) when off |
+
+Phase 1 does not write AAAA. Node IP not a valid IPv4 → that member is `error`.
+
+### Triggers
+
+| Trigger | Behavior |
+| --- | --- |
+| Manual sync (all / group / member) | reconcile |
+| Member added | initialize `proxied`, then enqueue sync |
+| Member removed / group deleted | delete the remote A managed by this module by default (configurable keep) |
+| Primary node / active / member `proxied` changed | re-sync the corresponding scope |
+| Node IP changed (heartbeat or manual) | enqueue members whose `active_node_id` points to that node |
+| Token not ready | refuse sync |
+
+Phase 1 does not do scheduled full reconciliation.
+
+### Reconcile (single member, idempotent)
+
+1. Resolve the CF Zone by the FQDN's registrable root domain, cache `cf_zone_id`.
+2. With a `cf_record_id`, prefer Update; if stale, list by `name+type=A`.
+3. **0 records** → Create; **exactly 1** → take over and Update; **multiple** → fail and tell the user to clean up in CF.
+4. Write back `cf_record_id`, `desired_ip`, `sync_status`, `synced_at` / `last_error`.
+5. On rate limiting, retry with bounded backoff.
+
+**Ownership:** only manage records cached by this module or taken over as "the only same-name A"; do not clear the Zone or touch other record types. After a user edits in the CF console, the next sync overwrites with the OpenFlare desired state.
+
+### Execution Carrier
+
+* Single record: can sync on the request path.
+* Whole group / per-node batch: Asynq tasks (`cloudflare:sync_member` / `sync_group` / `sync_by_node`), registered in `bootstrap`.
+* Per-member mutex to prevent concurrent double-writes.
+* Node IP change path delivers tasks **best-effort**, not blocking the heartbeat.
+
+## API (Admin Panel)
+
+Prefix: `/api/v1/d/cloudflare`, Session admin auth. Package: `internal/apps/openflare/cloudflare/`; routes: `internal/router/v1/openflare/register_cloudflare.go`.
+
+| Resource | Method & Path |
+| --- | --- |
+| Connection | `GET/PUT /connection`, `POST /connection/verify`, `POST /connection/clear` |
+| Overview | `GET /overview` |
+| Groups | `GET/POST /groups`, `GET /groups/:id`, `POST /groups/:id/update|delete|sync` |
+| Members | `GET/POST /groups/:id/members`, `POST .../members/:memberId/update|remove|sync` |
+| Available domains | `GET /domains/available` |
+
+* Success `response.OK`; failure `response.Abort*`; the Token is **never** returned in JSON.
+* Handlers separated from `logics.go`; the CF client is abstracted behind an interface for replaceability.
+
+## Frontend
+
+* Navigation: `frontend/lib/navigation/openflare-nav.ts` adds **Cloudflare** → `/cloudflare` (near Website Management / DNS Accounts).
+* Routes:
+  * `/cloudflare`: overview; guide to configure when not ready
+  * `/cloudflare/settings`: mixed Token config and test connection
+  * `/cloudflare/groups`, `/cloudflare/groups/[id]`: list and detail (members, orange-cloud, sync)
+* Services: independent service under `frontend/lib/services/openflare/`, extending `BaseService`.
+* Pages follow the existing title-bar and component-split conventions; destructive actions need double confirmation.
+* Copy that must be visible: sync overwrites module-managed A records; multiple same-name A records need manual cleanup; removal deletes remote records by default; phase 1 has no automatic failover.
+
+## Errors and Security
+
+* User-visible copy is module-internal constants; internal errors log via `pkg/logger`.
+* Typical: token not configured, invalid token, node without IP, no CF Zone, multiple same-name A records, rate limiting.
+* Token is only decrypted server-side for use; responses and logs must never contain plaintext tokens.
+
+## Data Migration
+
+* goose both dialects (PG/SQLite) create the three tables; defaults match Go zero values.
+
+## Key Decision Summary
+
+| Decision | Conclusion |
+| --- | --- |
+| Module shape | standalone Cloudflare pointing module, not embedded Zone fields |
+| Token | mixed: imported from DNS account or encrypted standalone |
+| Domain granularity | ZoneDomain (FQDN) |
+| Record shape | single A → active node IPv4 |
+| Failover | phase 2; heartbeat offline; phase 1 only stores backup/active |
+| Orange-cloud | member-level effective; group default only initializes |
+| SoT | DB tables as desired state drive CF |

+# Edge Cache Strategy Design
+
+You will learn: how OpenFlare's edge `proxy_cache` aligns with the Cloudflare default loop between "should cache" and "should not cache": request eligibility (extension/policy) × response shareability (origin `Cache-Control` / `Expires` / `Set-Cookie`), and the differences from the previous over-strict request bypass.
+
+This design is the productized chapter on "basic caching" in [System Architecture](./architecture.md); cache results in access logs are in [Observability Data Model §3.5.1](./observability-data-model.md).
+
+---
+
+## 1. Goals and Non-Goals
+
+### 1.1 Goals
+
+* **Close to CF default out of the box**: after enabling cache on a route, **only static extensions are cached by default** — HTML is not cached by default; **request session cookies / Authorization / client Cache-Control no longer cause a blanket BYPASS**.
+* **Cacheable content hits**: a logged-in user visiting `/_app/**/*.js` and other static assets can show `MISS` → `HIT`.
+* **Non-cacheable stays blocked**: policy not eligible (equivalent to CF `DYNAMIC`); origin `private` / `no-store`; responses with **`Set-Cookie` not stored** (aligned with CF OCC default); `all` is an advanced option with documented warnings.
+* **Default Edge TTL when no origin freshness**: aligned with CF's per-status default TTL (see §3.5).
+* **Consistent observability**: keep relying on `$upstream_cache_status` → three-state `cache_status` detail.
+* **Backward compatible**: legacy route `cache_policy=url` maps to `all`; policy enum and migration rules stay in [§5](#5-兼容与迁移).
+
+### 1.2 Non-Goals (later iterations)
+
+* Cache Rules expression engine
+* Forced Edge TTL ignoring origin `Cache-Control` (CF Cache Rules "Ignore cache-control")
+* Purge (by URL/prefix/site-wide)
+* Browser TTL rewriting, client `CF-Cache-Status` response header
+* Full RFC conditions: `Authorization` cached only when the response has `public`/`s-maxage`/`must-revalidate` (needs Lua; this iteration deletes the request-side bypass entirely, relying on policy + origin headers)
+* HEAD → GET conversion then cache
+* Hit-rate dashboard
+
+---
+
+## 2. Cloudflare Decision Loop (Alignment Baseline)
+
+CF default is a **two-stage decision**, **not** "request has Cookie → don't cache".
+
+### 2.1 Stage A — Eligible at Request Time
+
+| Condition | CF Result |
+| --- | --- |
+| Non-GET | not cached by default |
+| Extension not in default cacheable table, no Rules forcing eligible | **`DYNAMIC`** (no cache lookup) |
+| Extension in default table, or Rules eligible | continue to Stage B |
+| **Request Cookie** | **no effect by default** |
+| Cache Rules Bypass | `DYNAMIC` |
+
+CF's default cacheable extensions are keyed by **extension** rather than MIME; **HTML / JSON are not cached by default**.
+
+### 2.2 Stage B — Response Storeable (OCC on, Free/Pro/Biz default)
+
+| Condition | Result |
+| --- | --- |
+| `Cache-Control: no-store` / `private` | not stored |
+| `public` + `max-age>0`, or future `Expires` | cacheable |
+| No Cache-Control / Expires | still cacheable with per-status **default Edge TTL** (e.g. 200 → 120m) |
+| Response **`Set-Cookie`** (default cache level + OCC) | **not stored**, status tends toward **BYPASS** |
+| Request `Authorization` | cacheable only when the response also has `public` / `s-maxage` / `must-revalidate` (full condition simplified with Nginx this iteration, see §3.4) |
+
+### 2.3 Status Semantics (vs. Observability)
+
+| CF | Meaning | OpenFlare `cache_status` |
+| --- | --- | --- |
+| HIT / STALE / UPDATING / REVALIDATED | hit class | same-name or equivalent |
+| MISS / EXPIRED | fetch from origin | same-name |
+| BYPASS | eligible at request time, response not cacheable | `BYPASS` → UI "not cached" |
+| DYNAMIC | not eligible at request time | policy skip mostly `BYPASS` or empty → UI "not cached" |
+
+---
+
+## 3. Product Semantics
+
+### 3.1 Two-Level Switch (unchanged)
+
+* **Global** `openresty_cache_enabled`: generates `proxy_cache_path` etc.; when off, route-level cache directives are inert.
+* **Route** `cache_enabled`: whether to enable `proxy_cache` in that site's `location`.
+
+Cache logic only runs when both are on.
+
+### 3.2 Policy Enum
+
+| `cache_policy` | Meaning | New Default | Legacy Compatibility |
+| --- | --- | --- | --- |
+| **`static`** | only eligible when URI matches **standard static extensions** | **yes** | — |
+| **`all`** | after method bypass, no path/extension restriction (advanced; risk similar to CF Cache Everything) | no | legacy `url` → `all` |
+| **`suffix`** | custom extension list (`cache_rules`) | no | kept |
+| **`path_prefix`** | custom path prefix | no | kept |
+| **`path_exact`** | custom exact path | no | kept |
+
+Render layer: historical `url` is treated as `all`; API/UI only expose the enum above.
+
+### 3.3 Standard Static Extensions (built-in)
+
+Aligned with CF default "no HTML/JSON caching"; keeps modern frontend-friendly enhancements:
+
+```text
+css js mjs map
+ico cur gif jpg jpeg png webp avif svg svgz
+ttf otf woff woff2 eot
+mp3 mp4 webm ogg flac
+wasm pdf
+zip 7z gz tar
+```
+
+* **Excludes** `html` / `htm` / **`json`** (aligned with CF not caching JSON by default).  
+* **Includes** `map` / `mjs` / `wasm` (deliberate enhancement for sourcemap / ES module / WASM hits).  
+* Matching: `$uri` extension, case-insensitive:  
+  `if ($uri !~* \.(?:css|js|…)$) { set $openflare_skip_cache 1; }`
+
+### 3.4 Request-Side Bypass (after CF alignment)
+
+Only kept:
+
+1. `$request_method != GET` (HEAD included, consistent with current network; no CF HEAD→GET)
+
+**Removed** (previously over-strict, causing low hit rates):
+
+* Session-cookie regex
+* `$http_authorization != ""`
+* request `$http_cache_control` matching `no-cache|no-store|private`
+
+**How security still holds:**
+
+| Threat | Gate |
+| --- | --- |
+| Accidentally caching HTML/API | default `static` extensions (no html/json) |
+| Personalized content | origin `private` / `no-store` (respected by Nginx) |
+| Response writes session | **`Set-Cookie` → not stored** (§3.6) |
+| `all` too broad | UI/doc warning: needs correct origin Cache-Control |
+| API with Bearer | rely on policy (don't use `all` for APIs) + origin headers; full Auth conditional caching is later |
+
+### 3.5 Default Edge TTL (no origin freshness)
+
+Aligned with CF's per-status default TTL without `Cache-Control`/`Expires`, emitted in cache-enabled locations:
+
+| Status | TTL |
+| --- | --- |
+| 200, 206, 301 | 120m |
+| 302, 303 | 20m |
+| 404, 410 | 3m |
+
+```nginx
+proxy_cache_valid 200 206 301 120m;
+proxy_cache_valid 302 303 20m;
+proxy_cache_valid 404 410 3m;
+```
+
+* When the origin provides valid `Cache-Control` / `Expires`, the origin freshness wins (no `proxy_ignore_headers`).  
+* **No** forced Edge TTL override ignoring origin headers.
+
+### 3.6 Response Side: Set-Cookie Not Stored
+
+Aligned with CF OCC default: an eligible request whose origin returns **`Set-Cookie`** is **not written** into `proxy_cache` (read path may still have MISS/BYPASS semantics).
+
+```nginx
+proxy_no_cache $openflare_skip_cache $upstream_http_set_cookie;
+```
+
+(`proxy_no_cache` multi-arg: any non-empty and non-`"0"` arg means no write.)
+
+`proxy_cache_bypass` still only binds `$openflare_skip_cache` (request-side skip); the response side only affects **writes**, consistent with CF "eligible but response not cacheable".
+
+### 3.7 Relationship with Origin Headers
+
+* **Eligibility**: policy + method bypass.  
+* **Store / duration**: origin `Cache-Control` / `Expires` + default `proxy_cache_valid` + Set-Cookie gate + global `inactive`.  
+
+---
+
+## 4. Rendering and Data Flow
+
+```text
+Global cache_enabled?
+    │ no → no proxy_cache_* generated
+    ▼ yes
+Route cache_enabled?
+    │ no → location without proxy_cache
+    ▼ yes
+set $openflare_skip_cache 0
+    → non-GET → set 1
+    → policy if (static/all/suffix/…) → may set 1
+proxy_cache openflare_cache
+proxy_cache_methods GET
+proxy_cache_bypass $openflare_skip_cache
+proxy_no_cache $openflare_skip_cache $upstream_http_set_cookie
+proxy_cache_valid …
+    →
+access.log cache_status=$upstream_cache_status
+```
+
+### 4.1 Policy → Nginx Conditions
+
+| Policy | Extra Condition |
+| --- | --- |
+| `static` | `$uri` not matching built-in extension table → skip |
+| `all` | no extra path condition |
+| `suffix` | not matching `cache_rules` extensions → skip |
+| `path_prefix` / `path_exact` | same as current implementation |
+
+### 4.2 Code Areas Involved
+
+| Area | Path |
+| --- | --- |
+| Rendering | `pkg/render/openresty/render.go` (bypass, Set-Cookie, `proxy_cache_valid`, extension constants) |
+| Validation | `internal/apps/openflare/proxy_route/helpers.go` |
+| Model/defaults | creating a route defaults `cache_policy=static`; `url`→`all` on read/write |
+| Snapshot | `config_version` snapshot normalization |
+| UI | `proxy-routes/detail/components/cache-section.tsx` |
+
+---
+
+## 5. Compatibility and Migration
+
+| Data | Handling |
+| --- | --- |
+| `cache_policy=''` or `url` in DB (and cache enabled) | read / snapshot / render → **`all`** |
+| API write with enabled and empty policy | normalized to **`all`**; UI new-create with cache on **explicitly submits** `static` |
+| New routes | default **`static`** when cache enabled |
+| Bypass behavior change | **breaking vs. old implementation**: cookie/auth traffic goes from "not cached" to cacheable HIT; requires **republishing node configs** |
+| Default extensions | **remove `json`** from the table; sites relying on caching `*.json` can use custom `suffix` or `all` |
+
+**Release note:** document this alignment with the CF default model; hit rate expected to rise; `all` and wrong origin headers need ops self-check.
+
+---
+
+## 6. UI Copy Points (Cache Tab)
+
+* After enabling cache, default: **standard static assets** (summary extensions, **excluding HTML/JSON**; including map/mjs etc.).  
+* Options: standard static / all cacheable GET (advanced) / custom suffix / path prefix / exact path.  
+* CF-aligned notes:  
+  * login cookies are **not** separately skipped from caching;  
+  * origin `private` / `no-store` / response **`Set-Cookie`** are not written to the edge cache;  
+  * default Edge TTL used when no origin cache headers.  
+* **Advanced `all`**: warn "similar to Cache Everything; personalized pages must declare private/no-store from the origin".  
+* Global Performance cache master switch must be on.
+
+---
+
+## 7. Decision Matrix (Avoid Missed Judgments)
+
+| Scenario | CF | OpenFlare (this design) |
+| --- | --- | --- |
+| GET static + session Cookie + origin public max-age | HIT | HIT |
+| GET HTML + static policy | DYNAMIC | policy skip → not cached |
+| GET + all + origin private | not stored | not stored |
+| GET static + response Set-Cookie | BYPASS (OCC) | not stored |
+| GET + Authorization + static public | conditional cache | cacheable (simplified; rely on origin not marking sensitive APIs public) |
+| GET + no-CC 200 static | default 120m | `proxy_cache_valid` 120m |
+| DevTools Disable cache (request no-cache) | edge may still HIT by default | edge may still HIT by default |
+| POST | not cached | non-GET skip |
+
+---
+
+## 8. Decision Record
+
+| Decision | Choice | Reason |
+| --- | --- | --- |
+| Request Cookie bypass | **removed** | aligned with CF; restore static hit rate for logged-in users |
+| Request Authorization / Cache-Control bypass | **removed** | aligned with CF request-eligibility model; response gate as backstop |
+| Set-Cookie | **bind to proxy_no_cache** | aligned with CF OCC "response Set-Cookie not stored" |
+| Default Edge TTL | **per-status proxy_cache_valid** | aligned with CF default TTL when headerless, avoiding "never stored" |
+| Remove json from default table | **yes** | aligned with CF not caching JSON by default |
+| Keep map/mjs/wasm | **yes** | useful hits for modern frontend, deliberate enhancement |
+| Default cacheable scope | cache-on defaults to `static` | benchmarked to CF, reduces HTML/API mis-caching |
+| Legacy `url` | maps to `all` | doesn't narrow existing behavior |
+| Full Auth conditions / Purge / Rules | later | close the default loop first, then extend |

+# Product Boundaries
+
+You will learn: what OpenFlare is, its current stable capabilities, and the core product boundaries and repository structure layout you must follow when developing.
+
+OpenFlare is a self-hosted OpenResty control plane for single-team or single-organization internal operations.
+
+---
+
+## Project Positioning
+
+OpenFlare suits teams that need to centrally manage multiple OpenResty proxy nodes, with this positioning:
+* **Control/landing separation**: the Server control plane doesn't SSH into proxy nodes; Agents actively pull versions and apply them.
+* **Immutable config release**: full config versions are used for preview, release, activation, and one-click rollback.
+* **Integrated gateway hosting**: website reverse proxying, automatic TLS certificate issuance/renewal, WAF protection, intranet penetration (Tunnel), and Pages static hosting are integrated into one control plane.
+
+**Not this product's positioning**: multi-tenant cloud platforms, Kubernetes Ingress Controllers, service meshes, or general log platforms.
+
+---
+
+## Current Capabilities
+
+| Capability | Description | Detailed Design/Usage |
+| --- | --- | --- |
+| **Reverse proxy config management** | website rules (Proxy Route) as the aggregation boundary; multi-domain and multi-upstream load balancing | [Create a Reverse Proxy Config](../guide/proxy-config.md) |

+
+## Core Product Boundaries and Constraints
+
+When developing and contributing code, **you must strictly follow** these business boundaries and technical constraints; don't bypass them for temporary needs:
+
+### 1. Website Config and Upstream Constraints
+* **Single-site domain sharing policy**: one route rule corresponds to one website; the site's multiple domains share rate limit, cache, and reverse-proxy upstream config. Differential per-domain service config within the same rule is not supported.
+* **Upstream type mutual exclusion**: the upstream must be one of direct address (`direct`), intranet tunnel (`tunnel`), or Pages static hosting (`pages`); mixing within one rule is not allowed.
+* **Direct type restrictions**: a direct upstream can be a single or multiple pure `http://` or `https://` addresses (multi-address only supports plain `scheme://host[:port]`); non-HTTP protocols (TCP/UDP) upstreams are not supported.
+
+### 2. WAF Security Boundaries
+* **Allowlist priority**: the allowlist has absolute matching power. Only when an allowlist rule isn't hit do the global and custom blocklist filters trigger in order.
+* **GeoIP weak dependency**: geo access resolution fully depends on the node-local MaxMind DB. When GeoIP is abnormal or fails to resolve, the system must auto-ignore geo rules — **never** break IP-group filtering or the reverse-proxy main chain's availability.
+* **Runtime data decoupling**: OpenResty interception only reads Agent-synced local JSON, never talking to the Server DB. IP group member sync is decoupled from version release via Checksum differential pull for zero-reload smooth effect.
+
+### 3. Intranet Penetration Boundaries
+* **HTTP traffic only**: the tunnel components only support HTTP/HTTPS (based on frp's vhost mechanism for single-port domain-route reuse); standalone TCP/UDP port allocation is not supported yet.
+* **Dynamic relay config control**: a Relay node, after connecting to the Server, dynamically pulls and syncs global system config via heartbeats (e.g. whether the embedded FRPS Web UI and its port are enabled), but isn't part of the control plane's immutable config version release system.
+* **Tunnel/Node system isolation**: Tunnel clients make outbound connections from the intranet and are independent entities from control-plane-hosted edge Nodes (public nodes), authenticated with the dedicated `tunnel_token`.
+
+### 4. Pages Static Hosting Boundaries
+* **Pre-built artifact sources**: a project may stay manual-upload, or configure one Remote URL / public GitHub Release asset source. Remote and fixed tags only support manual ops; only GitHub latest enters scheduled checks and can opt into auto-update. Sources are switchable, but immutable deployments and the current production version don't get lost when editing or deleting a source.
+* **Archive and resource limits**: supports `zip`, `tar.gz` / `tgz`, `tar.xz` / `txz`, `tar.bz2` / `tbz2`, `tar`, `7z`. Archive cap controlled by `pages_max_package_size_mb` (default 100 MiB, range 1–2048); expanded single-file and total limits are 4× the package cap with a 100 MiB floor, at most 1,000 regular files. Both Server and Agent validate actual bytes and reject path traversal, symlinks/hard links, and special files.
+* **Build and runtime boundaries**: currently no source checkout or build execution from external git repos, and no edge Serverless, dynamic SSR, or preview subdomains. Future repo integration must use a separate `git_repository` Provider with a Server-side isolated build executor, emitting only restricted artifacts into the unified artifact pipeline; the Agent never receives repo credentials, external URLs, or clone/install/build commands.
+
+### 5. System and Version Boundaries
+* **Globally single active version**: all nodes pull and consume the same globally active config. Per-node-group differentiated config release isn't performed.
+* **Single-tenant architecture**: OpenFlare is for a single team deploying on a trusted internal network. Single-tenant by design; fine-grained multi-user roles or multi-tenant resource isolation aren't supported.
+* **External infra dependency**: the Server **must depend on** external Redis (or Valkey) for distributed coordination, the Asynq queue, and system cache. The relational DB is PostgreSQL, or SQLite when `database.enabled` is off. ClickHouse **optional**: when off, access logs and observability time series are handled by the current log primary DB (follows the business primary DB); when on, the「Switch Log Database」task can migrate to ClickHouse. Running without Redis is not supported. See [Log Store Decoupling](./logstore.md).

+# Uptime Kuma Sync Design
+
+You will learn: the design background of the OpenFlare × Uptime Kuma monitoring integration, the control-flow design based on the Socket.IO protocol, the anti-pollution model centered on tag isolation, and the differential incremental sync state machine.
+
+---
+
+## Requirements Analysis
+
+In a multi-node gateway architecture, monitoring system state and reverse proxy route state are usually disconnected:
+1. **High entry overhead**: every time the gateway control plane adds or decommissions a site, the admin must re-configure the corresponding probe address and alert policy in the monitoring system (e.g. Uptime Kuma).
+2. **Data inconsistency**: when a proxy route domain changes or switches to HTTPS, monitoring parameters are easily left un-updated, causing false positives or missed alerts.
+3. **Environment pollution risk**: a full "delete-recreate" sync in monitoring would wipe historical statistics and SLA curves, and would also affect other monitor tasks the user configured manually on the instance that are unrelated to the gateway.
+
+To address these, OpenFlare introduces a **Uptime Kuma auto-monitoring sync mechanism** based on the client/server model, achieving strongly consistent, low-overhead, zero-pollution synchronization between gateway site route definitions and the availability monitoring system.
+
+---
+
+## Core Architecture
+
+The Uptime Kuma sync subsystem runs entirely in the **Server control plane** background scheduler.
+
+```text
+  [ OpenFlare Control Plane / DB ]                    [ Uptime Kuma Instance ]
+              │                                             │

+              │                                             │
+      3. Connect to Socket.IO <──── 4. Socket.IO handshake & login ────┤
+              │                                             │
+              ├────── 5. Validate / create "OpenFlare" tag ──►│
+              ├────── 6. Compare site attrs vs Kuma monitor list ─►│
+              │                                             │
+              └────── 7. Execute differential ops (add / edit / delete) ─►│
+```
+
+The sync subsystem does not pass through the data-plane Agent nodes; the Server talks directly to Uptime Kuma's exposed Socket.IO endpoint. This reduces edge node network overhead and keeps auth credentials (Kuma username/password) safely inside the control plane.
+
+---
+
+## Tag Isolation and Anti-Pollution Design
+
+To run safely in a shared Uptime Kuma instance without disturbing manually created monitors, a **dedicated tag isolation mechanism** is used:
+
+1. **`OpenFlare`-specific tag**:
+   * On first connect, the sync routine calls `getTags` to fetch all tags in the instance.
+   * It checks whether a tag named `OpenFlare` exists (default color indigo `#4f46e5`). If not, it creates it automatically via the `addTag` API.
+2. **Filtered scope**:
+   * After fetching Uptime Kuma's monitor list (`monitorList`), the sync task only keeps monitors **tagged with `OpenFlare`**.
+   * All modification comparisons (`editMonitor`) and offline cleanups (`deleteMonitor`) operate **only within this filtered subset**. Any monitor not bound with the `OpenFlare` tag is "invisible" to the sync routine — perfect anti-pollution isolation.
+
+---
+
+## Differential Sync State Machine
+
+On each run, the sync routine computes a diff between OpenFlare's local config and Uptime Kuma's data, then executes different Socket.IO events based on the comparison:
+
+```mermaid
+stateDiagram-v2
+    [*] --> 检查站点状态与监控范围
+    
+    state "检查监控范围" as Scope {
+        [*] --> 校验站点是否启用并且在 Scope 内
+        校验站点是否启用并且在 Scope 内 --> 在Scope内 : 是
+        校验站点是否启用并且在 Scope 内 --> 不在Scope内 : 否
+    }
+
+    不在Scope内 --> 检查Kuma中是否存在同名且带标签的监控

+    在Scope内 --> 检查Kuma中是否存在同名监控
+    
+    state "比对属性" as Compare {
+        [*] --> 检查是否存在
+        检查是否存在 --> 新建监控项 : 否
+        检查是否存在 --> 比对元数据 : 是
+        比对元数据 --> 属性一致 : 匹配
+        比对元数据 --> 属性不一致 : 不匹配
+    }
+
+    新建监控项 --> 发送add指令并绑定Tag
+    属性不一致 --> 发送editMonitor指令
+    属性一致 --> 忽略
+
+    执行清理 --> 发送deleteMonitor指令
+    忽略 --> [*]
+```
+
+### 1. Monitor URL Normalization
+A site route in OpenFlare can configure multiple domains; the sync routine automatically extracts the primary domain and assembles a standard `http://` or `https://` prefix based on whether HTTPS is enabled.
+
+### 2. Compared Attribute Set
+If a same-named, tagged monitor already exists, the sync routine compares the following 5 key fields against the current gateway global option. Any mismatch triggers an update:
+* **URL**: `Url`
+* **Probe interval**: `Interval` (default 60s)
+* **Max retries**: `MaxRetries`
+* **Retry interval**: `RetryInterval` (default 60s)
+* **Request timeout**: `Timeout` (default 48s)
+
+---
+
+## Scheduler and High-Concurrency Protection
+
+1. **Cron-based single-thread execution**:
+   * The Server periodically (every 1 minute) probes via a background Cron Job whether the configured sync interval (`UptimeKumaSyncInterval`) is reached.
+   * The task uses mutex locking internally. If a previous sync request is still running due to network latency, the next schedule is skipped automatically, preventing concurrent Socket.IO connections from DDOS-ing the Uptime Kuma instance.
+2. **WebSocket state listening**:
+   * The sync routine uses Socket.IO's event listener; after the connection is established, it only proceeds to the differential algorithm once the full `monitorList` event list push is received, avoiding monitor deletion caused by incomplete data loading.

+# Login CAPTCHA Integration (Cap)
+
+This document describes the design of introducing **Cap** — an open-source CAPTCHA solution based on Proof-of-Work (PoW) and invisible browser fingerprint features — into the OpenFlare control plane, to protect the login API against brute-force attacks and credential-stuffing by crawlers.
+
+---
+
+## 1. Business Background and Product Scope
+
+### Background and Pain Points
+The OpenFlare login endpoint `/api/v1/user/login` lacks user-dimension protection; attackers can use proxy pools to perform credential stuffing and brute-force attacks on high-privilege accounts (such as `root`). At the same time, standard visual CAPTCHAs are unfriendly to login-page UX and accessibility.
+
+### Product Scope and Technology Choice
+* **Technology choice**: Cap (a Proof-of-Work-driven, invisible, image-free CAPTCHA solution).
+  - **Core principle**: the client (Widget/page) obtains a proof-of-work (PoW) challenge from the server, computes the solution in the browser background, and sends the answer back. The server verifies the answer to complete human-machine verification.
+  - **Advantages**: invisible, image-free, no dependency on external third-party API nodes (private), tiny package size.
+* **Integration scope**: the control-plane Server login API (`/api/v1/user/login`) and the frontend login page.
+* **Config granularity**: admins can toggle the CAPTCHA on/off anytime via the console Option table (`cap_login_enabled`).
+
+---
+
+## 2. System Architecture and Interaction Sequence
+
+### 2.1 Module Responsibilities
+1. **Frontend**:
+   * Introduces the `cap-widget` (React 19 custom element) on the login page.
+   * On form submit, accompanies the submission with the `cap-token` solved by the Widget.
+2. **Server (control-plane backend)**:
+   * Exposes `POST /api/cap/challenge` to distribute the PoW challenge and a signed JWT token to the client.
+   * Exposes `POST /api/cap/redeem` to verify the submitted PoW solution and issue a login credential (Redeem Token) with an expiry time.
+   * Stores the Redeem Token and its expiry in the in-memory/Redis cache.
+   * In `POST /api/v1/user/login`, when CAPTCHA protection is enabled, first validates and consumes (single-use) the corresponding `cap-token`.

+* **CAPTCHA carrier**: placed in the HTTP Request Header `X-Cap-Token`.
+
+---
+
+## 4. Replay Attack Protection and Security Trade-offs
+1. **JWT temporary state binding**: the challenge is signed into the JWT payload at generation time, including an expiry limit (10 minutes).
+2. **Replay interception (nonce consumption)**: when the client calls `/redeem` to submit the solution, the backend marks the JWT signature as used in the cache. Re-submitting the same solution package returns `already_redeemed`.
+3. **Redeem single-use (one-time invalidation)**: when the client logs in and submits the `cap-token`, the backend immediately deletes the key from the cache after validating it, preventing attackers from extracting historical valid `cap-token`s for login replay.
+4. **Seamless verification**: by tuning parameters like `c` (challenge count) and `d` (difficulty), you balance solve time against anti-crawler strength; users solve silently in the background without interrupting the login flow.

+# Log Store Decoupling
+
+You will learn: which tables are log-purpose, why they must not be pinned to ClickHouse, and which code path a new log table must follow.
+
+Observability fields and the reporting protocol are still governed by [Observability Protocol & Tables](./observability-data-model.md); this document only defines **where data is stored and how to switch databases**.
+
+---
+
+## 1. Goals
+
+* **ClickHouse optional**: when not enabled, PostgreSQL (or SQLite when the primary DB is off) fully takes over writes, queries, aggregation, and cleanup.
+* **Upper layers don't touch the underlying DB**: apps only face `internal/repository/logstore` (or the `repository` facade). `repository/analytics` and `db.ChConn` / `db.ChDB` are only used by logstore's ClickHouse implementation.
+* **Switchable**: 「Switch Log Database」in Task Management copies data between PostgreSQL/SQLite and ClickHouse and flips the primary; writes are frozen during migration, the switch only happens on success, and source data is not deleted.
+
+---
+
+## 2. What Counts as a Log Table
+
+A table enters logstore only if it meets all of:
+
+* Append-only writes, almost no row updates
+* Query or aggregate by time, deletable by retention days
+* Must still support writes and queries when ClickHouse is off
+* Does not participate in transactional consistency for websites / nodes / certificates, etc.
+
+**Don't** make these log tables: Zones, nodes, config versions, task executions, upload metadata. These go through the business primary DB `repository`.
+
+Current log domains:
+
+| Domain | Interface | Tables |
+| --- | --- | --- |
+| Node access logs | `AccessLogStore` | `of_node_access_logs` |
+| Observability time series | `ObservabilityStore` | `of_node_metric_snapshots` / `of_node_edge_health` / `of_node_obs_frps` / `of_node_obs_frpc` |
+| User access audit | `UserAccessLogStore` | `w_user_access_logs` |
+
+Hourly materialized views on ClickHouse (e.g. `of_access_log_hourly`) only serve CH query acceleration. PostgreSQL / SQLite **do not** build isomorphic aggregation tables; queries aggregate in real time from raw logs.
+
+---
+
+## 3. Layering
+
+| Layer | Path | Responsibility |
+| --- | --- | --- |
+| Abstraction | `internal/repository/logstore` | Interfaces + `Active` / `BuildForMigration`; selects implementation by `log_database` |
+| CH implementation | `logstore/clickhouse_store.go` | Delegates to `repository/analytics` (native batch + existing aggregation SQL) |
+| Primary DB implementation | `logstore/postgres_store.go` | PostgreSQL (high-frequency tables partitioned monthly) and SQLite (plain tables) share GORM |
+| Model | `internal/model/analytics` | Entities and batch SQL, no IO |
+| Enqueue | `chwriter` / `risk_control` + `batchwriter` | `FlushFunc` calls `logstore.Active`; node logs / observability enqueue via hooks |
+| Constraint | `logstore/imports_test.go` | apps are forbidden from importing `repository/analytics` |
+
+`log_database` has only two legal states: **follow the business primary DB** (`postgres` or `sqlite`) or **`clickhouse`**. "Primary PostgreSQL + log SQLite" does not exist. `log_database` / `log_db_migration` are protected and cannot be changed from the admin panel.
+
+At startup: `log_database=clickhouse` but ClickHouse not enabled → startup is refused; you must re-enable ClickHouse, switch back to the primary DB, and only then turn it off.
+
+---
+
+## 4. Switch Protocol
+
+Task type `of_log_db_switch` (admin name 「Switch Log Database」), parameter `target`.
+
+1. Validate the target is legal and not the current DB.
+2. Write `log_db_migration=migrating`, drain in-flight batchwriter (`Drain`, not `Stop` writer). Writes return a clear error afterward (HTTP 503), not queued backlog.
+3. Clear the target log tables, then copy by id in pages; call `EnsurePartitions` on the PostgreSQL target before copying.
+4. Only on full success write `log_database=target` and clear the migration marker; on failure clear the marker and writes continue on the source DB.
+5. Source data is not deleted; re-clear the target before retry to guarantee idempotency.
+
+Don't invent another switch protocol, and don't connect `analyticsrepo` directly inside tasks.
+
+---
+
+## 5. Adding a New Log Table
+
+Column names must be identical across the three goose migrations (ClickHouse / PostgreSQL / SQLite). Key points:
+
+* High-frequency tables: CH uses `MergeTree` + `toYYYYMM`; PG uses `PARTITION BY RANGE(time column)` with the partition key in the primary key; SQLite uses a plain table + indexes.
+* IDs use snowflake `uint64`, preserved as-is during migration.
+* Writes go through a dedicated `batchwriter`; flush calls `logstore.Active`, not `analyticsrepo.BatchInsert`.
+* The switch task's `copy*` must cover the new table; cleanup uses existing `log_retention_days_*` or `metric_retention_days`, don't use the wrong TTL.
+
+Runtime config: [Configuration Reference · Log Storage](../reference/configuration.md#8-日志存储log-database).

+# Agent Reporting Protocol and Observability Data Model
+
+You will learn: the **data structures** of the refactored Agent heartbeat/WS reports, how the Server **parses and writes** them, and the **target table structures** in ClickHouse / relational DBs.  
+**No protocol compatibility layer**: Agents upgrade via destroy-and-recreate or binary replacement; old fields are not parsed, old buffers are discarded wholesale.
+
+This design is the **protocol & storage chapter** of [Edge Observability & Business Traffic Stats Refactor](./observability-design.md); implement against the fields and DDL in this document.
+
+**First read the transport overview and examples:** [Observability Transport Model](./observability-transport-model.md).
+
+---
+
+## 1. Design Goals
+
+| Goal | Description |
+| --- | --- |
+| Agent reports only facts | details + host readings + edge health instant state; no business pre-aggregation |
+| One business detail table | access logs are the only L1 write path |
+| Aggregation in DB/control plane | hourly summaries come from ClickHouse MV or queries; the Agent never writes summary tables |
+| No field overlap | `bytes_sent` = data provided; NIC `network_*` = host; no business `openresty_tx` anymore |
+| Evolvable | new fields optional; missing numeric values default to 0; removed legacy protocol fields are not parsed |

+
+## 3. Agent Report Data Structures (protocol v2)
+
+### 3.1 Top-Level `NodePayload`
+
+Transport: HTTP heartbeat body and WebSocket `status` messages share the same structure.
+
+```json
+{
+  "schema_version": 2,
+  "node_id": "n_xxx",
+  "name": "edge-1",
+  "ip": "1.2.3.4",
+  "version": "3.3.0",
+  "ext_version": "",
+  "current_version": "cfg-checksum-or-version",
+  "last_error": "",
+  "profile": { },
+  "host_metrics": { },
+  "edge_health": { },
+  "access_logs": [ ],
+  "buffered": [ ],
+  "health_events": [ ],
+  "waf_ip_group_checksums": { "1": "md5..." }
+}
+```
+
+| Field | Type | Required | Description |
+| --- | --- | --- | --- |
+| `schema_version` | int | suggested | fixed to `2` (this design) |
+| `node_id` | string | ✅ | node ID |
+| `name` | string | ✅ | display name |
+| `ip` | string | ✅ | reporting IP |
+| `version` / `ext_version` | string | ✅ | Agent version |
+| `current_version` | string | | locally active config version summary |
+| `last_error` | string | | latest sync/runtime error, nullable |
+| `openresty_status` | string | ✅ (when OpenResty present) | **latest health-state authoritative field** → written to PG node table |
+| `openresty_message` | string | | **latest health-description authoritative field** → written to PG node table (**not into CH**) |
+| `profile` | object | | host overview, report on change (may throttle) |
+| `host_metrics` | object | suggested each beat | L3 resource snapshot |
+| `edge_health` | object | suggested each beat | L2 connection time series + status aligned with top level |
+| `access_logs` | array | | this beat's incremental access details |
+| `buffered` | array | | offline backfill fact batches (see §3.6) |
+| `health_events` | array | | edge health events |
+| `waf_ip_group_checksums` | map | | for differential sync, not an observability lake |
+
+**Removed, Server no longer parses (no compatibility layer):**
+
+| Old Field | Disposition |
+| --- | --- |
+| `traffic_report` | not in the protocol; not stored |
+| `openresty_observation` | not present; connections/status go through `edge_health` |
+| `snapshot` | not present; only `host_metrics` |
+| `buffered_observability` | not present; only `buffered` |
+
+### 3.2 `profile` — Host Overview (low frequency)
+
+Maps to relational `of_node_system_profiles` (or an existing equivalent), **not into the ClickHouse detail lake**.
+
+```json
+{
+  "hostname": "edge-1",
+  "os_name": "linux",
+  "os_version": "...",
+  "kernel_version": "...",
+  "architecture": "amd64",
+  "cpu_model": "...",
+  "cpu_cores": 8,
+  "total_memory_bytes": 16106127360,
+  "total_disk_bytes": 107374182400,
+  "uptime_seconds": 864000,
+  "reported_at_unix": 1720000000
+}
+```
+
+| Field | Semantics |
+| --- | --- |
+| hardware/OS description fields | factual readings |
+| `reported_at_unix` | Agent collection time (UTC seconds) |
+
+### 3.3 `host_metrics` — Host Capacity (L3)
+
+**All readings, no 24h business totals.**  
+NIC/disk bytes are **kernel cumulative counter raw values** (monotonically increasing, may reset on restart); CPU is an instant percentage; memory/disk usage is current usage.
+
+```json
+{
+  "captured_at_unix": 1720000000,
+  "cpu_usage_percent": 12.5,
+  "memory_used_bytes": 4294967296,
+  "memory_total_bytes": 16106127360,
+  "storage_used_bytes": 50000000000,
+  "storage_total_bytes": 107374182400,
+  "disk_read_bytes": 9000000000,
+  "disk_write_bytes": 12000000000,
+  "network_rx_bytes": 500000000000,
+  "network_tx_bytes": 800000000000
+}
+```
+
+| Field | Type | Semantics | How Server Uses It |
+| --- | --- | --- | --- |
+| `captured_at_unix` | int64 | sampling time | `captured_at` |
+| `cpu_usage_percent` | float | instant CPU% | store directly; average for trends |
+| `memory_*` / `storage_*` | int64 | current used/total | store directly; compute usage rate |
+| `disk_read_bytes` / `disk_write_bytes` | int64 | **cumulative** IO bytes | store raw; adjacent deltas at query time |
+| `network_rx_bytes` / `network_tx_bytes` | int64 | **cumulative** NIC bytes | store raw; adjacent deltas at query time → "host NIC in/outbound" |
+
+> The Agent is **forbidden** from replacing cumulative values with "this period's delta" before reporting (otherwise Server deltas would be wrong).
+
+### 3.4 `edge_health` — OpenResty Edge Health (L2)
+
+**Instant state only, no business throughput.**
+
+```json
+{
+  "captured_at_unix": 1720000000,
+  "status": "healthy",
+  "message": "",
+  "connections": 42
+}
+```
+
+| Field | Type | Semantics |
+| --- | --- | --- |
+| `status` | string | `healthy` / `unhealthy` / `unknown` (must match top-level `openresty_status`) |
+| `message` | string | status description (may be reported; **only backfills PG latest state, not into CH**) |
+| `connections` | int64 | stub_status Active connections |
+
+#### Health-State Authoritative Sources (converged)
+
+| Data | Authoritative Storage | Description |
+| --- | --- | --- |
+| **Current** OpenResty health + description | **PG node table** `openresty_status` / `openresty_message` | UI badges, lists, alerts use this |
+| **Time series** health status + connections | **CH** `of_node_edge_health` (`status`, `connections`) | connection curves / health history; **no message column** |
+| Agent report | top-level status/message + `edge_health` | Server normalizes both statuses aligned; message **only written to PG** |
+
+So: "is it unhealthy now" → read PG; "connections over the past 24h" → read CH.
+
+### 3.5 `access_logs[]` — Access Details (L1, single business truth)
+
+Agent: tail access.log → parse JSON lines → report fields as-is (path may be truncated).
+
+```json
+{
+  "logged_at_unix": 1720000001,
+  "remote_addr": "203.0.113.10",
+  "host": "www.example.com",
+  "path": "/api/v1/ping",
+  "status_code": 200,
+  "bytes_sent": 1024,
+  "request_length": 128,
+  "request_time_ms": 15,
+  "user_agent": "Mozilla/5.0 ...",
+  "cache_status": "HIT"
+}
+```
+
+| Field | Type | Required | Source (OpenResty) | Business Meaning |
+| --- | --- | --- | --- | --- |
+| `logged_at_unix` | int64 | ✅ | parse `$time_iso8601` | request completion time |
+| `remote_addr` | string | ✅ | `$remote_addr` | client IP → UV |
+| `host` | string | ✅ | `$host` | domain → Zone ownership |
+| `path` | string | ✅ | `$request_uri`, Agent may truncate | path |
+| `status_code` | int | ✅ | `$status` | status code |
+| `bytes_sent` | int64 | ✅ | **`$body_bytes_sent`** | **data provided** (response body) |
+| `request_length` | int64 | suggested | `$request_length` | **data received** |
+| `request_time_ms` | int64 | optional | `$request_time * 1000` | latency; default 0 |
+| `user_agent` | string | suggested | `$http_user_agent` | UA; may truncate on store |
+| `cache_status` | string | suggested | **`$upstream_cache_status`** | edge cache result (see §3.5.1) |
+
+**Explicitly not reported by Agent (written by Server):**
+
+* `region` / country: GeoIP resolved at insert time  
+* `id` / `created_at`: Server-generated  
+* `node_id`: from payload / auth context  
+
+**Explicitly not reported:**
+
+* `upstream_addr` / origin address / `origin_fetched`: no origin-endpoint tracking; "did it fetch from origin" is only derived from `cache_status` at the control plane (§3.5.1)
+
+### 3.5.1 `cache_status` — Cache Hit and Origin Fetch (detail-first)
+
+**Goal (phase 1):** access log details/list can show "cache hit / origin fetch / no cache used".  
+**Caliber:** only store the raw OpenResty `$upstream_cache_status`; **no upstream address reported**.
+
+#### Raw Values (stored)
+
+| Value | Meaning (OpenResty) |
+| --- | --- |
+| `HIT` | cache hit |
+| `MISS` | miss, fetched from upstream |
+| `BYPASS` | cache skipped (e.g. method/cookie/policy caused `$openflare_skip_cache`) |
+| `EXPIRED` | expired then origin fetch |
+| `STALE` | served stale |
+| `UPDATING` | background updating, may return old cache |
+| `REVALIDATED` | revalidated, still used cache |
+| `-` or empty | didn't pass through `proxy_cache` (e.g. Pages local static, non-proxy location) |
+
+#### UI Three-State Derivation (not stored)
+
+Control-plane display uses derived enum `cache_outcome`, **not written to CH**:
+
+| Three-State | Condition (`cache_status`) | Suggested List Label |
+| --- | --- | --- |
+| **Cache hit** | `HIT` / `STALE` / `REVALIDATED` / `UPDATING` | hit |
+| **Origin fetch** | `MISS` / `EXPIRED` | origin |
+| **No cache used** | `BYPASS` / `-` / `""` | not cached |
+
+Details can show both the three-state and the raw `cache_status`.
+
+#### Boundaries
+
+* Pages static / locations without `proxy_cache`: mostly empty or `-` → **no cache used**, must not be labeled "hit".  
+* Detail pages show cache state; hit-rate dashboards and hourly dimensions can extend from the same column.
+
+**Per-heartbeat count suggestion:**
+
+* Soft cap e.g. 2000 lines/beat; overflow goes into `buffered` next batch, **forbidden** to compress into a TrafficReport in the Agent.
+
+### 3.6 `buffered[]` — Offline Backfill (facts only)
+
+```json
+{
+  "captured_at_unix": 1719999900,
+  "host_metrics": { },
+  "edge_health": { },
+  "access_logs": [ ]
+}
+```
+
+| Field | Description |
+| --- | --- |
+| `captured_at_unix` | batch collection/buffer time, used for ack and dedup window |
+| `host_metrics` / `edge_health` / `access_logs` | same structures as the main payload; empty blocks may be omitted |
+
+**Forbidden** to carry `traffic_report` or rx/tx throughput in buffered.
+
+### 3.7 `health_events[]`
+
+```json
+{
+  "event_type": "openresty_unhealthy",
+  "severity": "critical",
+  "message": "...",
+  "triggered_at_unix": 1720000000,
+  "metadata": { }
+}
+```
+
+Written to the relational health-event table (existing model suffices), not into the access log lake.
+
+### 3.8 Go Protocol Structures

+## 4. Server Parsing and Storage Flow
+
+### 4.1 Entry Points
+
+* HTTP: `POST /api/v1/agent/...` heartbeat (existing path)  
+* WebSocket: `type=status` payload = `NodePayload`  
+* Auth: `X-Agent-Token` → binds `node_id` (payload.node_id must match the token node)
+
+### 4.2 Processing Pipeline (single payload)
+
+```text
+1. Deserialize NodePayload
+2. Normalize
+   - schema_version < 2:
+       host_metrics ← snapshot
+       edge_health.status ← openresty_status
+       edge_health.connections ← openresty_observation.connections (if present)
+       traffic_report → drop
+       openresty_observation.rx/tx → drop
+       buffered ← buffered_observability
+   - path truncated again, status clamped, negative bytes → 0
+3. Relational transaction (node latest state)
+   - update node online time, IP, version, edge_health.status/message
+   - upsert profile (if present)
+   - insert health_events (if present)
+4. ClickHouse async batch (log on failure; doesn't block heartbeat response config delivery)
+   a. access_logs + buffered[].access_logs
+        → fill region (GeoIP)
+        → assign snowflake id
+        → BatchInsert of_node_access_logs
+   b. host_metrics + buffered[].host_metrics
+        → of_node_metric_snapshots
+   c. edge_health + buffered[].edge_health
+        → of_node_edge_health (connections + status snapshot only, optional)
+5. Return heartbeat response (settings / active_config / waf diff)
+6. If using buffer ack: confirm by the list of buffered.captured_at_unix
+```
+
+### 4.3 Normalization Rules (hard constraints)
+
+| Rule | Behavior |
+| --- | --- |
+| `logged_at` ahead of now+5m | clamp to now or drop the line (pick one in implementation and unit-test it) |
+| `logged_at` older than now−TTL | still writable; relies on table TTL cleanup |
+| empty `host` | allowed, aggregated into "unassigned" |
+| `bytes_sent` / `request_length` < 0 | set to 0 |
+| single batch access_logs > N | truncate and alert-metric it (or only queue into buffer), never switch to pre-aggregation |
+| duplicate backfill | CH tolerates a few duplicate rows; queries approximate with sum (no forced exact dedup) |
+
+### 4.4 Field Mapping Table (report → table)

+## 5. Table Structures (DDL)
+

+
+### 5.1 L1 Fact Table: `of_node_access_logs`
+
+```sql

+```
+
+| Column | Type | Source |
+| --- | --- | --- |
+| `id` | UInt64 | Server |
+| `node_id` | String | auth/payload |
+| `logged_at` | DateTime64(3) | `logged_at_unix` |

+| `request_length` | UInt64 | report → **data received** |
+| `request_time_ms` | UInt32 | report optional |
+| `created_at` | DateTime64(3) | Server now |
+
+**Migration:** the current table already has `bytes_sent` / `request_length` / `request_time_ms` / `user_agent`; cache status adds:
+
+```sql
+ALTER TABLE of_node_access_logs
+    ADD COLUMN IF NOT EXISTS cache_status String DEFAULT '';
+```
+
+### 5.2 L1 Hourly Rollup (Server-side MV)
+
+**Agent forbidden to write.** Serves dashboard/node 24h fast queries of request count, error count, bytes.
+
+**Implemented choice: `SummingMergeTree` + no UV column.**
+
+```sql
+CREATE TABLE IF NOT EXISTS of_access_log_hourly
+(
+    node_id         String,
+    hour            DateTime('UTC'),
+    host            String,
+    request_count   UInt64,
+    error_count     UInt64,
+    bytes_sent      UInt64,
+    request_length  UInt64
+)
+ENGINE = SummingMergeTree()
+PARTITION BY toYYYYMM(hour)
+ORDER BY (node_id, hour, host)
+TTL hour + INTERVAL 90 DAY;
+
+CREATE MATERIALIZED VIEW IF NOT EXISTS of_access_log_hourly_mv
+TO of_access_log_hourly
+AS
+SELECT
+    node_id,
+    toStartOfHour(logged_at) AS hour,
+    host,
+    toUInt64(count()) AS request_count,
+    toUInt64(countIf(status_code >= 500)) AS error_count,
+    sum(bytes_sent) AS bytes_sent,
+    sum(request_length) AS request_length
+FROM of_node_access_logs
+GROUP BY node_id, hour, host;
+```
+
+Historical hours (details stored before the MV existed) need a one-time backfill, see migration `202607180003_backfill_access_log_hourly.sql` (ANTI JOIN to prevent duplicates).
+
+#### UV Policy (must follow)
+
+| Scenario | Data Source | Algorithm | Notes |
+| --- | --- | --- | --- |
+| **Window total UV** (dashboard totals, node cards, Zone totals) | `of_node_access_logs` details | `uniqExact(remote_addr)` (`TrafficSummary` / node aggregation) | **single authority**; never sum hourly UV |
+| **24h trend line request/error/bytes** | `of_access_log_hourly` preferred, fall back to detail buckets | `sum(request_count)` etc. | hourly path **doesn't fill** `unique_visitor_count` (always 0) |
+| **24h trend per-hour UV** | detail bucket path only | in-bucket `uniqExact` | when using hourly, UI should show empty/0 or hide the UV series; **forbidden** to `sum(UV)` over hourly rows |
+
+**Why hourly doesn't store UV:**
+
+1. `SummingMergeTree` can only safely merge addable counts; `uniqExact` across parts needs `AggregatingMergeTree` + state, heavier to implement and query.  
+2. Even if hourly UV were stored, **summing over multi-hour windows severely overestimates** (the same IP is counted once per hour).  
+3. Product "24h unique visitors" only recognizes whole-window `uniqExact`; the trend chart's main series are requests/errors/bytes — per-hour UV is not a primary metric.
+
+### 5.3 L3 Fact Table: `of_node_metric_snapshots` (kept, semantics clarified)
+
+```sql
+CREATE TABLE IF NOT EXISTS of_node_metric_snapshots
+(
+    id                  UInt64,
+    node_id             String,

+PARTITION BY toYYYYMM(captured_at)
+ORDER BY (node_id, captured_at, id)
+TTL toDateTime(captured_at) + INTERVAL 30 DAY
+SETTINGS index_granularity = 8192;
+```
+
+Columns match production; **docs and API must label `network_*` as host NIC cumulative values**.
+
+### 5.4 L3 Hourly Rollup: `of_node_metric_capacity_hourly` (kept)
+
+Existing min/max used for cumulative-counter hourly increment approximation + CPU/memory averages. Logic unchanged:
+
+* `network_tx_max - network_tx_min` ≈ that hour's host outbound  
+* **must not** be used for "data provided"
+
+### 5.5 L2 Fact Table: `of_node_edge_health` (new, replaces throughput-style openresty table)
+
+```sql
+CREATE TABLE IF NOT EXISTS of_node_edge_health
+(
+    id           UInt64,
+    node_id      String,
+    captured_at  DateTime64(3, 'UTC'),
+    status       LowCardinality(String),  -- healthy / unhealthy / unknown
+    connections  Int64,
+    created_at   DateTime64(3, 'UTC')
+)
+ENGINE = MergeTree()
+PARTITION BY toYYYYMM(captured_at)
+ORDER BY (node_id, captured_at, id)
+TTL toDateTime(captured_at) + INTERVAL 30 DAY
+SETTINGS index_granularity = 8192;
+```
+
+| Column | Description |
+| --- | --- |
+| `status` | instant health (same source as PG current state; for time series, not the sole UI authority) |
+| `connections` | current connection count |
+
+**No** `message` column (description only in PG latest state).  
+**No** `openresty_rx_bytes` / `openresty_tx_bytes`.
+
+### 5.6 Relational DB (node latest state, not an analytics lake)
+
+Separate from the observability lake, keeping "latest one":
+
+| Table (logical name) | Purpose | Key Columns |
+| --- | --- | --- |
+| `of_nodes` (or current node table) | online, version, IP | `last_seen_at`, `openresty_status`, `openresty_message`, `agent_version` |
+| `of_node_system_profiles` | profile upsert | hostname, cpu_cores, total_memory_bytes, ... |
+| health-event table | `health_events` | event_type, severity, message, triggered_at |
+
+> Actual physical table names follow the repo's existing GORM models; this design doesn't force renames, only forces **business throughput no longer written into node tables**.
+
+### 5.7 Deprecated Tables (stop writing → delete after TTL)
+
+| Table | Reason | Replacement |
+| --- | --- | --- |
+| `of_node_request_reports` | Agent pre-aggregation | `of_node_access_logs` + hourly |
+| `of_node_traffic_hourly` + MV | depends on request_reports | `of_access_log_hourly` |
+| `of_node_obs_openresty` | contains business rx/tx | `of_node_edge_health` |
+| `of_node_openresty_hourly` + MV | business throughput deltas | `of_access_log_hourly` bytes_* |
+
+Relay-specific `of_node_obs_frps` / `of_node_obs_frpc` **kept** (not this Agent's main path, but same CH observability).
+
+---
+
+## 6. Table-Protocol Cross-Reference
+
+| Product Concept | Protocol Field | Table.Column | Aggregation |
+| --- | --- | --- | --- |
+| Data provided | `access_logs[].bytes_sent` | `of_node_access_logs.bytes_sent` | `sum` |
+| Data received | `access_logs[].request_length` | `...request_length` | `sum` |
+| Request count | row count | — | `count` |
+| UV (window total) | `remote_addr` | same details | `uniqExact` (**forbidden** to sum hourly UV) |
+| Top domains | `host` | same | `group by` |
+| Status distribution | `status_code` | same | `group by` |
+| Source region | — | `region` (Server) | `group by` |
+| Host NIC outbound | `host_metrics.network_tx_bytes` | `of_node_metric_snapshots.network_tx_bytes` | time-series delta |
+| Host NIC inbound | `network_rx_bytes` | same | delta |
+| Disk read/write | `disk_*_bytes` | same | delta |
+| CPU/memory | instant fields | same | avg |
+| OpenResty connections | `edge_health.connections` | `of_node_edge_health.connections` | latest/avg |
+| OpenResty health | `edge_health.status` | node table + optional CH | latest |
+
+**Mappings that no longer exist:**
+
+| Old Concept | Old Field | Disposition |
+| --- | --- | --- |
+| OpenResty outbound | `openresty_tx_bytes` | removed; use data provided |
+| OpenResty inbound | `openresty_rx_bytes` | removed; use data received |
+| Window request report | `traffic_report` | removed |
+
+---
+
+## 7. OpenResty Log Format (aligned with details)
+
+Target `log_format` (ensures the `bytes_sent` key = body; includes UA and cache status):
+
+```nginx
+log_format openflare_json escape=json
+  '{"ts":"$time_iso8601","host":"$host","path":"$request_uri",'
+  '"remote_addr":"$remote_addr","status":$status,'
+  '"request_time":$request_time,'
+  '"bytes_sent":$body_bytes_sent,"request_length":$request_length,'
+  '"user_agent":"$http_user_agent",'
+  '"cache_status":"$upstream_cache_status"}';
+```
+
+Agent parsing:
+
+* `ts` → `logged_at_unix`  
+* `bytes_sent` → protocol `bytes_sent` (provided)  
+* `request_length` → protocol `request_length`  
+* `request_time` → optional `request_time_ms = round(sec * 1000)`  
+* `user_agent` → protocol `user_agent`  
+* `cache_status` → protocol `cache_status` (passed through as-is, no three-state compression)
+
+---
+
+## 8. Upgrade Strategy (no compatibility layer)
+
+| Item | Strategy |
+| --- | --- |
+| Agent upgrade | **destroy-and-recreate** preferred; **binary replacement** allowed |
+| Protocol | only schema v2 fields; legacy JSON fields not parsed |
+| Local observability buffer | if still in old format (containing `snapshot` / `openresty_observation` / `traffic_report`) or corrupt → **delete the file wholesale**, rebuild at runtime |
+| Read path | business APIs **only read** access_logs (and hourly); current health reads PG; connection series reads CH edge_health |
+| Old Agents | must upgrade; the control plane provides no v1 dual-read path |
+

+# Edge Observability and Business Traffic Statistics Refactor
+
+You will learn: the problems this refactor solves (dashboard "OpenResty outbound" vs "Zone data provided" inconsistency, field and aggregation redundancy), and how the target architecture makes **the Agent report only facts and the Server interpret facts**, with access logs as the single source of truth for business traffic.
+
+---
+
+## 1. Goals
+
+### 1.1 Problems to Solve
+
+1. **Dual sources of truth**: business throughput comes from both access-log aggregation and OpenResty observability deltas, and the numbers never match long-term.
+2. **Agent over-computes**: the edge pre-aggregates `TrafficReport`, throughput accumulation, and the control plane aggregates again — semantics are hard to evolve and reconcile.
+3. **Field semantic overlap**: "OpenResty outbound" and "data provided" are the same business problem for users, but the system uses two field sets and two pipelines.
+4. **Instant vs cumulative mixed**: 60-second window counts are treated as process cumulative values for 24h deltas, causing severe underestimation.
+5. **UI induces wrong comparisons**: the dashboard and Zone page use similar "traffic/data" wording without declaring scope and caliber differences.
+
+### 1.2 Refactor Goals
+
+| Goal | Description |
+| --- | --- |
+| **Single business truth** | request count, data provided, UV, status distribution, Top domains etc. **only** derived from access logs (and Server-side rollups) |
+| **Agent reports only facts** | detail logs + machine readings + health snapshots; **business UV/TopN/24h totals pre-aggregation is forbidden** |
+| **Field convergence** | one business concept maps to one authoritative field; machine NIC and business delivery strictly separated by name |
+| **Reconcilable** | global "data provided" ≈ sum of per-Zone "data provided" (difference only from unbound/unknown Hosts) |
+| **Evolvable** | changing time windows, TopN, ownership rules only changes the Server, not the Agent |
+
+### 1.3 Non-Goals (outside this design)
+
+* Building a general log platform, full-log long-term archive, or search product.
+* Replacing ClickHouse / removing the analytics DB dependency.
+* Reworking Relay / OpenFlared host metric collection (principles align, but not in this round's protocol main path).
+* Real-time streaming alert engine, APM tracing (the OpenTelemetry server side already exists and is orthogonal to this business traffic model).
+
+---
+
+## 2. Scope and Constraints
+
+### 2.1 Product Constraints (inherited)
+
+* Single-tenant, single globally active config; observability introduces no multi-tenant billing isolation.
+* Access logs and time-series observability use the switchable log primary DB (ClickHouse by default; switchable to PostgreSQL/SQLite), see [Log Store Decoupling](./logstore.md).
+* Agent has no inbound control, Pull model; during offline periods local OpenResty keeps serving, and observability can buffer locally and backfill.
+
+### 2.2 Engineering Constraints
+
+* Agent stays lightweight: parse log lines, read `/proc`, health checks; no business analysis.
+* Control-plane API errors still use the unified envelope and `response.Abort*`.
+* Access log field changes must update both the OpenResty `log_format` and the Agent parser simultaneously; Agent and control plane ship at the same version, no legacy protocol parsing.
+
+---
+
+## 3. Design Principles
+
+### Principle P1: Agent Reports Facts, Server Interprets Facts
+
+```text
+Agent  = collection + reliable delivery (raw / near-raw)
+Server = storage + aggregation + ownership + trends + reconciliation
+```
+
+**Allowed edge processing (collection)**
+
+* Parsing JSON access.log lines into structured fields
+* path length caps, dropping invalid lines, skipping observability-port's own requests
+* Reading NIC/CPU/memory counters as **raw values**
+* Batching, compression, offline buffering and retries
+
+**Forbidden edge processing (business computation)**
+
+* UV / Top domains / status histograms / window request_count as authoritative metrics
+* Maintaining "business in/out cumulative" for the dashboard
+* Zone / domain ownership stats, country distribution (country can be resolved at Server insert time)
+
+### Principle P2: Single Truth for Business Traffic = Access Logs
+
+| Business Question | Single Answer |
+| --- | --- |
+| How much data was provided | `sum(bytes_sent)` |
+| How many requests | `count()` |
+| How many unique visitors | `uniqExact(remote_addr)` (or product-defined hashing) |
+| Status codes / Top domains | `group by` on logs |
+
+### Principle P3: Three Metric Layers Never Mixed
+
+| Layer | Name | Purpose | Typical Fields |
+| --- | --- | --- | --- |
+| L1 Business delivery | Business Traffic | user & Zone reconciliation, dashboard business trends | access log |
+| L2 Edge health | Edge Health | is OpenResty alive, current connections | status, connections |
+| L3 Host capacity | Host Capacity | capacity planning, is the machine saturated | CPU, memory, disk, **NIC** |
+
+Never name L3 NIC or L2 instant counts as "data provided"; never draw L1 and L3 on the same summary card without labeling semantics.
+
+### Principle P4: One Business Concept, One Field
+
+* **Data provided** ≡ response body delivered ≡ "OpenResty outbound (business meaning)" in legacy copy → **keep only `bytes_sent` aggregation**
+* **Data received** (optional) ≡ request-side volume → log `request_length` aggregation
+* **Host outbound** ≡ `network_tx` delta, copy must include "host/NIC"
+
+---
+
+## 4. Pre-Refactor Problems (Baseline)
+
+### 4.1 Pre-Refactor Data Flow (redundant)
+
+```text
+One HTTP request
+  │
+  ├─ access.log line
+  │     → Agent tail → AccessLogs[]
+  │     → CH of_node_access_logs
+  │     → Zone "data provided" ✅
+  │
+  ├─ Lua shared dict window/cumulative counts
+  │     → /openflare/observability
+  │     → TrafficReport + OpenrestyObservation(rx/tx)
+  │     → CH request_reports / obs_openresty
+  │     → dashboard "OpenResty in/outbound" ❌ easily inconsistent with Zone
+  │
+  ├─ second access.log aggregation (fallback when observability endpoint fails)
+  │     → yet another TrafficReport / throughput
+  │
+  └─ host network_rx/tx
+        → Snapshot → "host" curve in network trends
+```
+
+### 4.2 Field Overlap
+
+| User Perception | System Field A | System Field B | Problem |
+| --- | --- | --- | --- |
+| Outbound / provided | `openresty_tx_bytes` | `bytes_sent` | duplicate business semantics |
+| Inbound | `openresty_rx_bytes` | `request_length` (log) | duplicate business semantics |
+| Request count | `TrafficReport.request_count` | `count(access_logs)` | duplicate aggregation, window easily double-counted |
+| Outbound (machine) | `network_tx_bytes` | (no business equivalent) | should be named separately, never reconciled with business |
+
+### 4.3 Typical Failure Modes
+
+1. Window counts treated as cumulative deltas → 24h business throughput severely underestimated.  
+2. Hourly rollup `max−min` broken for resetting counters.  
+3. Zone uses logs, dashboard uses observability → users think the system is wrong.  
+4. Changing caliber requires syncing Lua, Agent state accumulation, Server deltas, and frontend copy.

+### 5.2 Responsibility Matrix
+
+| Capability | Agent | Server | Frontend |
+| --- | --- | --- | --- |
+| Write access.log | OpenResty | — | — |
+| Read and report details | ✅ | store | — |
+| sum/count/uniq/TopN | ❌ | ✅ | display |
+| Zone domain filtering | ❌ | ✅ | select Zone |
+| Host CPU/memory/NIC | read raw values and report | delta/average | node/dashboard resource area |
+| OpenResty connections | read instant and report | latest value | node health |
+| Business 24h in/outbound | ❌ | log aggregation | uniformly called "data provided/received" |
+
+---
+
+## 6. Metrics and Field Model
+
+### 6.1 Authoritative Field Table (target)
+
+#### L1 Business Delivery (from access logs)
+
+| Concept | Storage Field | Aggregation | Display Name |
+| --- | --- | --- | --- |
+| Request time | `logged_at` | window filter | — |
+| Node | `node_id` | group | — |
+| Client IP | `remote_addr` | `uniq` → UV | Unique visitors |
+| Host | `host` | group / Zone mapping | Domain |
+| Path | `path` | optional | — |
+| Status code | `status_code` | group | Status distribution |
+| **Data provided** | **`bytes_sent`** | **`sum`** | **Data provided** |
+| **Data received** | **`request_length`** | **`sum`** | **Data received** (optional display) |
+| Region | `region` (resolved & written by Server) | group | Source region |
+
+> Note: the JSON key in the OpenResty `log_format` may keep the name `bytes_sent`; the value must come from **`$body_bytes_sent`** (consistent with production), representing response body delivered, i.e. "data provided".
+
+#### L2 Edge Health (instant; no 24h business totals)
+
+| Concept | Field | Description |
+| --- | --- | --- |
+| OpenResty health | `openresty_status` / message | existing |
+| Current connections | `openresty_connections` | stub_status |
+| (optional) rough recent-window QPS | node detail "right now" only, **never** authoritative 24h totals | if implemented must be labeled "instant" |
+
+#### L3 Host Capacity
+
+| Concept | Field | Display Name |
+| --- | --- | --- |
+| CPU / memory / disk usage | `host_metrics` | keep |
+| NIC cumulative bytes | `network_rx_bytes` / `network_tx_bytes` | **Host NIC in/outbound** |
+| Disk IO cumulative | `disk_read_bytes` / `disk_write_bytes` | Disk read/write |
+
+### 6.2 Removed Fields (no compatibility layer)
+
+| Original Field | Disposition | Reason |
+| --- | --- | --- |
+| `openresty_tx_bytes` / `openresty_rx_bytes` | **removed** | business bytes follow access logs |
+| `TrafficReport` and TopN/window UV | **removed** | edge pre-aggregation |
+| Agent state business lifetime accumulators | removed | violates P1 |
+| Lua shared dict business throughput/window request counts | removed | not the delivery main path |
+
+### 6.3 Naming Reference (frontend copy enforced)
+
+| Forbidden Copy | Correct Copy | Data Source |
+| --- | --- | --- |
+| OpenResty outbound (business volume) | **Data provided** | `sum(bytes_sent)` |
+| OpenResty inbound (business volume) | **Data received** | `sum(request_length)` |
+| Network outbound (unspecified) | **Host NIC outbound** | `network_tx` delta |
+| Two cards: data provided vs outbound | **keep only one business card** | logs |
+
+---
+
+## 7. Agent Design
+
+### 7.1 Heartbeat Payload (target protocol)
+
+Keep and strengthen:
+
+```text
+NodePayload
+  identity / version / openresty_status / openresty_message  # latest state → PG
+  profile                  # host overview (low frequency)
+  host_metrics             # L3 resource readings (incl. NIC cumulative raw values)
+  edge_health              # L2: status + connections (CH time series; message not in CH)
+  access_logs[]            # L1 details (main path)
+  health_events[]
+  buffered[]               # buffered facts above, not reports
+  waf_ip_group_checksums
+```
+
+Removed from the protocol (no compatibility layer):
+
+```text
+traffic_report
+openresty_observation
+snapshot / buffered_observability aliases
+```
+
+### 7.2 Access Log Reporting Requirements
+
+Each detail at minimum contains:
+
+| Field | Required | Note |
+| --- | --- | --- |
+| `logged_at_unix` | ✅ | request completion time |
+| `remote_addr` | ✅ | UV |
+| `host` | ✅ | Zone mapping |
+| `path` | ✅ | may be truncated |
+| `status_code` | ✅ | |
+| `bytes_sent` | ✅ | body bytes, data provided |
+| `request_length` | ✅ | data received |
+
+Agent responsibilities:
+
+1. Tail `access.log` by offset (reset offset on truncation/rotation, **only report new lines still present in the file**).  
+2. Parse into structured form, batch into heartbeat / WS.  
+3. Offline writes to local buffer, backfill by window once connected.  
+4. **No sum/count/uniq on details.**
+
+### 7.3 Host Snapshot
+
+* Keep reporting NIC/disk **cumulative counter raw values** (not business pre-aggregation).  
+* Server does non-negative deltas between adjacent samples → host trends.  
+* This is unrelated to "data provided"; the UI must display it in a separate section.
+
+### 7.4 OpenResty Local Observability
+
+Converged state:
+
+* Keep: health checks, `stub_status` current connections.  
+* The main path no longer relies on `log.lua` shared dict business counts; `/openflare/observability` only returns health and connection snapshots, not business report sources.
+
+### 7.5 Relationship with the Agent Design Doc
+
+This design strengthens "pure data landing" in [Agent & Publish Model](./agent-design.md):
+
+* Config and certificates: land and report applied state.  
+* Observability: only carry facts, not business conclusions.
+
+---
+
+## 8. Server Design
+
+### 8.1 Storage
+
+| Input | Table | Description |
+| --- | --- | --- |
+| `access_logs[]` | `of_node_access_logs` | authoritative business details |
+| `host_metrics` | `of_node_metric_snapshots` | L3; NIC/disk cumulative |
+| `openresty_status` / `openresty_message` | **PG node table** | L2 **latest-state authority** (message only here) |
+| `edge_health` | `of_node_edge_health` | L2 time series: status + connections (**no message**) |
+
+GeoIP: continue resolving `remote_addr` → `region` in the Server insert path, not in the Agent.
+
+### 8.2 Aggregation Layer (unified)
+
+All business trends and Zone stats share the same query semantics:
+
+```text
+filter: logged_at ∈ [since, until]
+optional: node_id / host IN (...)
+metrics:
+  request_count     = count()
+  unique_visitors   = uniqExact(remote_addr)
+  bytes_provided    = sum(bytes_sent)      -- data provided
+  bytes_received    = sum(request_length)  -- data received
+  series folded by hour/bucket
+  distributions by status_code / host / region
+```
+
+Implementation locations:
+
+* Zone: `GET .../zones/:id/stats` (existing, align field naming)  
+* Dashboard: overview traffic / business network trends **switch to the same aggregation** (global, no host filter or Top filter)  
+* Node detail: business volume = the same aggregation filtered by that `node_id`; host NIC still uses metric deltas  
+
+### 8.3 Derived Rollups (optional performance path)
+
+When detail queries over all nodes for 24h are too heavy, allow **Server-side** materialized views:
+
+```text
+of_access_log_hourly
+  (hour, node_id, host, request_count, bytes_sent, bytes_received, ...)
+```
+
+Constraints:
+
+* Derived only by CH from `of_node_access_logs`; **Agent is forbidden from writing this table directly**.  
+* Zone / dashboard prefer reading the rollup, falling back to details (similar to the existing metric hourly policy).
+
+### 8.4 Decommissioned Analytics Paths
+
+| Path | After Migration |
+| --- | --- |
+| `BuildNetworkTrendPoints` delta on openresty_rx/tx | deleted, or keep only `network_*` host curves |
+| `of_node_obs_openresty` throughput fields | stop writing; drop table or shrink columns after TTL expiry |
+| `of_node_request_reports` + traffic hourly | business trends no longer depend on it; table can be deprecated wholesale |
+| Dashboard compact openresty_tx series | change to bytes_provided series |
+
+---
+
+## 9. API and Frontend
+
+### 9.1 Semantically Unified Response Fields
+
+Business stats APIs should uniformly use:
+
+```json
+{
+  "request_count": 0,
+  "unique_visitors": 0,
+  "bytes_provided": 0,
+  "bytes_received": 0,
+  "series": [
+    {
+      "bucket_started_at": "...",
+      "request_count": 0,
+      "unique_visitors": 0,
+      "bytes_provided": 0,
+      "bytes_received": 0
+    }
+  ]
+}
+```
+
+API business byte fields use `bytes_provided` / `bytes_received` (access-log aggregation); no more openresty throughput aliases.
+
+### 9.2 Dashboard
+
+* **Business area**: request trend, data provided, data received (optional), status codes, Top domains, source regions — all L1.  
+* **Resource area**: CPU/memory, **host NIC**, disk IO — all L3.  
+* **Forbidden**: showing "OpenResty in/outbound" in the business area as a metric reconciled with Zone.
+
+Suggest splitting or retitling "24-hour network and disk trends":
+
+* "24-hour business traffic" → `bytes_provided` / `bytes_received` / requests  
+* "24-hour host network and disk" → `network_*` / `disk_*`
+
+### 9.3 Zone `/websites/:id`
+
+* Keep cards like "total data provided".  
+* Data and the dashboard business area use **the same aggregation function**, only `hosts = zone domain list`.  
+* Docs and UI may note: the global dashboard includes all Hosts; this page is only this Zone.
+
+### 9.4 Node Detail
+
+* Business throughput: that node's `sum(bytes_sent)` etc.  
+* OpenResty: health + current connections.  
+* NIC: clearly "host".
+
+---
+
+## 10. OpenResty and Log Format
+
+### 10.1 Keep
+
+Existing JSON `log_format` core fields:
+
+```text
+ts, host, path, remote_addr, status, request_time,
+bytes_sent (= $body_bytes_sent), request_length
+```
+
+### 10.2 Changes
+
+* No longer rely on log-phase writes of business shared dict counts as control-plane input.  
+* Observability-port requests continue not writing business stats (or `access_log off`).
+
+### 10.3 Agent Parsing
+
+* Protocol `NodeAccessLog` adds `request_length`.  
+* Legacy log lines missing fields default to 0, not blocking the whole batch.
+
+---
+
+## 11. Upgrade and Migration (no compatibility layer)
+
+### 11.1 Phase Review (shipped)
+
+| Phase | Content |
+| --- | --- |
+| **M1–M5** | read path switches to access logs; protocol v2; stop pre-aggregation; edge_health + access_log_hourly; drop old tables and API compat fields |
+
+### 11.2 Upgrade Strategy
+
+* **Agent: destroy-and-recreate preferred**; binary replacement allowed.  
+* On binary replacement: the local old observability buffer (including `snapshot` / `openresty_observation` / `traffic_report`) is **deleted wholesale**, rebuilt after running.  
+* Server **does not** parse v1 fields, **does not** dual-read request_reports / openresty throughput.  
+* Detail-missing periods: business charts are empty or partial; **never** impersonate data provided with NIC or removed openresty throughput.
+
+### 11.3 Data Backfill
+
+* Historical "data provided" follows access logs.  
+* Before `of_access_log_hourly` is created, history is backfilled with goose SQL (ANTI JOIN to prevent duplicates).
+
+### 11.4 Health-State Authority
+
+* **Current state**: PG `openresty_status` / `openresty_message`.  
+* **Time series**: log primary DB `of_node_edge_health` (status + connections; no message).
+
+### 11.5 UV
+
+* **Whole-window unique visitors**: `uniqExact(remote_addr)` (dashboard totals, Zone totals).  
+* **Bucketed UV** (Zone curves): per-bucket uniq, **not summable across buckets**; UI must note it.  
+* **Hourly trend path**: don't plot / fill per-hour UV (hourly table has no UV).
+
+---
+
+## 12. Storage and Capacity
+
+* Business trends rely on details or hourly rollups; watch `of_node_access_logs` TTL and sampling.  
+* If details are too large: prefer **Server-side rollup** rather than restoring Agent pre-aggregation.  
+* For high-cardinality path scenarios, limit detail path length (existing); aggregation doesn't do global Top over full paths by default.
+
+---
+
+## 13. Risks and Trade-offs
+
+| Risk | Mitigation |
+| --- | --- |
+| Large detail volume makes CH and heartbeat heavy | batching, compression, sampling policy evaluation; Server rollup; limit per-batch count |
+| Brief log loss lowers business volume | local buffer and rotation handling; monitor access log collection lag |
+| Users still compare "NIC outbound" with "data provided" | UI sections and copy enforce the "host" prefix |
+| Old Agents stay online long-term | **no compatibility layer**; Agents must be upgraded/rebuilt |
+
+**Why not keep Agent pre-aggregation as an optimization?**
+
+* Saving bandwidth re-splits the truth, drifts calibers, and repeats this problem.  
+* Optimization belongs in Server derived tables and queries, not edge business computation.
+
+---
+
+## 14. Key Decision Summary
+
+| Decision | Choice | Rejected Alternative |
+| --- | --- | --- |
+| Business traffic truth | access logs | OpenResty dict / TrafficReport |
+| Agent role | report only facts | edge UV/TopN/throughput accumulation |
+| "Outbound" vs "provided" | merged into data provided | dual fields and dual pipelines long-term |
+| NIC traffic | independent L3, separate copy | reconciled side-by-side with business outbound |
+| Performance | CH rollup | Agent pre-aggregation |
+| Migration | switch read path first, then slim Agent | drop details first, rely on pre-aggregation |

+## 0. Remember the Three Layers First
+
+| Layer | Question Answered | Single Data Source | Product Examples |
+| --- | --- | --- | --- |
+| **L1 Business delivery** | How much data provided? How many requests? | **access.log details** | data provided, request count, UV, status codes, Top domains |
+| **L2 Edge health** | Is OpenResty alive? Current connections? | **local `/openflare/observability`** | node health, current connections |
+| **L3 Host capacity** | How are CPU/memory/disk/NIC? | **OS readings** | capacity trends, host NIC |
+
+**The three layers are never reconciled against each other.**  
+"Data provided" ≠ "current connections" ≠ "host NIC outbound".

+
+| Role | Does | Doesn't |
+| --- | --- | --- |
+| OpenResty | writes access.log; maintains connection counts | no direct reporting to the control plane |
+| Agent | **collects facts and reports them** | **does not compute** UV/TopN/24h data provided |
+| Server | stores + **aggregates/interpreters** | does not trust edge business pre-summaries |
+
+---
+
+## 2. Collection Frequency (defaults)
+
+| Action | Default Frequency | Config |
+| --- | --- | --- |
+| Agent → Server report | **every 3 seconds** a full payload | `heartbeat_interval` / control-plane `agent_heartbeat_interval` (ms, default `3000`) |
+| Tail access.log when packing | **with report** (new lines since last report) | same |
+| GET `/openflare/observability` when packing | **with report** (reads **current** connection snapshot) | same |
+| Read host metrics when packing | **with report** | same |
+| OpenResty writes access.log | **1 line at each request end** | unrelated to heartbeat |
+| Connection counts update in-process | **on connection change** (kernel-maintained) | unrelated to heartbeat |
+| Offline replay window | keep ~**60 minutes** by default | `observability_replay_minutes` |
+| Node offline detection | ~**60s** without a successful heartbeat | `node_offline_threshold` (default `60000` ms) |
+
+**Notes:**
+
+- The Agent has **no separate "sampling clock"**; **sampling points = report points** (default 3s).  
+- access.log is "per-request continuous writes"; the Agent only **moves incremental lines** periodically.  
+- `/openflare/observability` is **not** "business stats start being counted when called"; for connections it **reads Nginx's existing instantaneous values**.
+
+Transport channels:
+
+- **HTTP heartbeat**: POST the full payload at the interval.  
+- **WebSocket**: after connecting, sends `status` messages at the same interval (same content shape); HTTP heartbeat is not double-sent then.

+| 1 | OpenResty `log_format openflare_json` | writes one JSON line per request to `access_log_path` |
+| 2 | Agent **tails increments** by file offset | new lines between two heartbeats |
+| 3 | parse and put into `access_logs[]` | overlong paths may be truncated; **no sum/count** |
+
+Log format (OpenResty variables):
+
+```text
+ts            ← $time_iso8601
+host          ← $host
+path          ← $request_uri
+remote_addr   ← $remote_addr
+status        ← $status
+request_time  ← $request_time
+bytes_sent    ← $body_bytes_sent     【data provided = response body bytes】
+request_length← $request_length      【data received】
+user_agent    ← $http_user_agent
+cache_status  ← $upstream_cache_status  【cache status; UI can derive hit/origin/un-cached】
+```
+
+Observability-port requests **don't write** business access.log (separate server with `access_log off`).

+    "user_agent": "Mozilla/5.0",
+    "cache_status": "HIT"
+  }
+]
+```
+
+| Field | Explanation |
+| --- | --- |
+| `bytes_sent` | **data provided** (single request); global/Zone totals = Server `sum` |
+| `request_length` | **data received** (single request) |
+| `logged_at_unix` | request completion time (business timeline) |
+| `host` | used for Zone domain filtering |
+| `cache_status` | `$upstream_cache_status` as-is; detail/list can derive three states (hit/origin/un-cached); **no upstream address reported** |
+| no `region` | **written by Server at insert time** via GeoIP |
+
+### 4.3 How the Server Uses It (product metrics)
+
+| Product Metric | Algorithm (L1 only) |
+| --- | --- |
+| Data provided | `sum(bytes_sent)` |
+| Data received | `sum(request_length)` |
+| Request count | `count()` |
+| UV | `uniqExact(remote_addr)` |
+| Status distribution | `group by status_code` |
+| Top domains | `group by host` |
+| Zone page | same + `host IN (that Zone's domains)` |
+| Dashboard business area | same, global or Top-filtered |
+
+Stored in: `of_node_access_logs` (optional Server-side `of_access_log_hourly` acceleration, **Agent never writes it**).
+
+### 4.4 Report Frequency
+
+```text
+Request happens ──immediately──► write access.log
+Agent every 3s ──moves──► new lines in those 3s (possibly 0, possibly many)
+Server ──immediately/batched──► CH
+```
+
+Business volume correctness does **not** depend on 3s alignment; 3s only affects "detail arrival latency at the control plane" and per-packet line count.
+

+
+## 5. L2 Health: edge_health and `/openflare/observability`
+
+### 5.1 Local Monitoring Endpoint
+
+**Data collection endpoint:**
+
+```http
+GET http://127.0.0.1:{openresty_observability_port}/openflare/observability
+```
+
+Default port: **18081** (`openresty_observability_port`).
+
+**Responsibility:** answers "how is OpenResty right now", **not** "how much business data was provided".
+
+#### Response Example
+
+```json
+{
+  "ok": true,
+  "captured_at_unix": 1721289600,
+  "connections": {
+    "active": 42,
+    "reading": 0,
+    "writing": 1,
+    "waiting": 41
+  }
+}
+```
+
+| Field | Instant? | Source | Description |
+| --- | --- | --- | --- |
+| `ok` | this probe | returns 200 → true | liveness |
+| `captured_at_unix` | sampling time | `ngx.time()` | aligned with report |
+| `connections.active` | **instant** | Nginx connection state (original stub_status Active) | current active connections |
+| `reading` / `writing` / `waiting` | **instant** | same, subdivided | optional but recommended |
+
+**Not returned (removed):**
+
+| Old Field | Reason |
+| --- | --- |
+| `request_count` / `error_count` / UV / status_codes / top_domains | business window summaries, now from access log |
+| `openresty_rx_bytes` / `openresty_tx_bytes` | duplicates data provided/received and error-prone |
+| `source_countries` | never implemented; countries go through Server GeoIP |
+| `server.accepts/handled/requests` | process cumulative counters, easily confused with business requests; not on the main path |
+
+**`/openflare/stub_status`:** kept; `/openflare/observability` internally reads that endpoint to assemble the connection-count JSON, and the Agent health check also probes it directly.
+
+### 5.2 Collection Mechanism (read snapshot)
+
+```text
+Nginx maintains Active connections etc. on connect/disconnect
+        │
+Agent GET /openflare/observability
+        │
+only reads "current values" and returns JSON
+```
+
+- No access.log scanning, no 60-second business averages.  
+- Returns an **instant gauge snapshot**.
+
+### 5.3 Report Example (packed into NodePayload)
+
+```json
+"edge_health": {
+  "captured_at_unix": 1721289600,
+  "status": "healthy",
+  "message": "",
+  "connections": 42
+}
+```
+
+| Field | Source |
+| --- | --- |
+| `status` / `message` | Agent health probe (config validation/process etc., may work with the observability endpoint's `ok`); must align with top-level `openresty_status` / `openresty_message` |
+| `connections` | observability endpoint `connections.active` |
+
+**Storage split (authoritative sources):**
+
+| Content | Written To |
+| --- | --- |
+| latest `status` + `message` | **PG node table** (UI / list / alerts) |
+| time-series `status` + `connections` | **CH `of_node_edge_health`** (**no message**) |
+
+---
+
+## 6. L3 Host: host_metrics
+
+### 6.1 Where Collection Comes From
+
+The Agent reads the local machine (e.g. `/proc`, disk stats), **once per packet**.
+
+| Field | Semantics | Description |
+| --- | --- | --- |
+| `cpu_usage_percent` | instant | current CPU% |
+| `memory_*` / `storage_*` | instant used/total | usage rates computed at Server or display layer |
+| `disk_read_bytes` / `disk_write_bytes` | **cumulative counter** | kernel cumulative IO |
+| `network_rx_bytes` / `network_tx_bytes` | **cumulative counter** | **host NIC**, not data provided |
+
+### 6.2 Report Example
+
+```json
+"host_metrics": {
+  "captured_at_unix": 1721289600,
+  "cpu_usage_percent": 12.5,
+  "memory_used_bytes": 4294967296,

+  "network_rx_bytes": 500000000000,
+  "network_tx_bytes": 800000000000
+}
+```
+
+### 6.3 How the Server Handles Cumulative Fields
+
+```text
+store raw-value time series
+when displaying "NIC outbound over this period":
+  delta = current - previous
+  if delta < 0 → treat as restart/counter reset, record this segment's increment as 0, continue from new baseline
+  if delta >= 0 → record into that period's increment
+```
+
+- The Agent **reports raw values**, never computes 24h totals at the edge.  
+- **Forbidden** to `sum` cumulative raw values as business volume.  
+- Copy must be **"host NIC"**, never "data provided / OpenResty outbound".
+
+Stored in: `of_node_metric_snapshots` (optional capacity hourly MV).

+- host NIC outbound = sum of non-negative `network_tx` deltas over metrics  
+
+The three numbers **need not be equal**.
+
+---
+
+## 8. Offline Backfill `buffered`
+
+When reporting fails, the Agent caches **the same kind of facts** locally by window (default ~60 minutes), then packs them into `buffered[]` after recovery:
+
+```json
+"buffered": [
+  {
+    "captured_at_unix": 1721289500,
+    "host_metrics": { },
+    "edge_health": { },

+
+- Only facts, no legacy TrafficReport.  
+- Server processing logic is identical to the main fields.

+# Origin Error Page Design
+
+You will learn: when an origin or the gateway returns a specified error status code, how OpenFlare replaces the pass-through response with a globally configurable page; how the config enters the immutable config version; and how the edge OpenResty keeps the real HTTP status code while displaying it in the page.
+
+This design is the productized complement of the reverse proxy traffic path in [System Architecture](./architecture.md); the config release model is in [Agent & Publish Model](./agent-design.md).
+
+---
+
+## 1. Goals and Non-Goals
+
+### 1.1 Goals
+
+* **Interceptable**: for a user-configured status code set, replace the previously pass-through origin/Nginx default error response with a unified HTML.
+* **Disableable**: when the global switch is off, behavior matches today (pass-through / Nginx default page).
+* **Visible by default**: enabled by default, default status code tag `500-599`, default minimal OpenFlare error page.
+* **Customizable**: admins can edit the full HTML online; empty HTML means the built-in default template.
+* **Status passthrough**: the HTTP response `status` keeps the original error code (e.g. 502, 522); the page body shows the same value via `{{status}}`.
+* **Globally unified**: a single config under sidebar「Website Management → Response Pages」shared by all reverse proxy routes.
+* **Consistent with release**: the config persists via Option, enters the config version snapshot, and is distributed with release/rollback.
+
+### 1.2 Non-Goals
+
+* Per-route / per-Zone error page overrides
+* Hosting error pages via file upload (online HTML only)
+* Modifying WAF / PoW / rate-limit's own response pages (unless the user adds those status codes to the list)
+* Pages static route error pages
+* Multi-language error pages, brand asset CDN
+
+---
+
+## 2. Product Behavior
+
+### 2.1 When to Replace
+
+| Condition | Behavior |
+| --- | --- |
+| Switch on and the response status falls in the expanded set | return custom/default HTML, **status unchanged** |
+| Switch on with GET-only enabled, non-GET request returns a matching status | pass through the origin's raw response, no replacement |
+| Switch off | no `error_page` directives generated, pass through |
+| Status not in the set | no replacement |
+| Pages upstream routes | this feature is not applied |
+| Origin returns 2xx/3xx/4xx successfully (not configured) | no replacement |
+
+In all-methods mode, `proxy_intercept_errors on` is enabled on the reverse proxy `location`, so **origin-returned** matching 5xx etc. are also intercepted, not just gateway-local 502s; GET-only mode switches to Lua header/body filters that only replace GET response bodies.
+
+### 2.2 Status Code Tag Syntax
+
+Each Tags Input entry:
+
+| Form | Example | Meaning |
+| --- | --- | --- |
+| Single code | `522` | only that code |
+| Closed range | `500-599` | expand including endpoints |
+
+* Valid range: single codes and range endpoints must be in **400–599**; `lo ≤ hi`.  
+* Default tag list: `["500-599"]`.  
+* Persist the **raw tags** (JSON array string); expand, dedupe, and sort at render time.  
+* If the expanded result is empty while enabled → save rejected.  
+* Invalid tags → save rejected with a readable error.
+
+### 2.3 Page Placeholders
+
+| Placeholder | Meaning |
+| --- | --- |
+| `{{status}}` | the current response status code (consistent with the HTTP status) |
+| `{{host}}` | request Host |
+
+Both custom HTML and the default template support these placeholders; replaced at the edge at runtime. Unused placeholders may be omitted from the template.
+
+### 2.4 Default Page
+
+Built-in minimal white-background OpenFlare default page: large pass-through status code, short English description, Host, and a brand footer. Supports `{{status}}` / `{{host}}`; the frontend can load prebuilt styles from the built-in template catalog on the edit page.
+
+---
+
+## 3. Config Model
+
+### 3.1 Option Keys (`w_system_configs` / OpenFlare Option API)
+
+| Key | Type | Default | Description |
+| --- | --- | --- | --- |
+| `origin_error_page_enabled` | bool string | `true` | master switch |
+| `origin_error_page_status_codes` | JSON string array | `["500-599"]` | raw tags |
+| `origin_error_page_html` | text | `""` | empty = built-in default; max **256 KiB** |
+| `origin_error_page_get_only` | bool string | `false` | replace error pages only for GET; other methods pass through |
+
+Reuses APIs:
+
+* `GET /api/v1/d/option`  
+* `POST /api/v1/d/option/update-batch`  
+
+No new resource routes. goose migration writes the seed; constants defined in the `internal/model` config key area.
+
+### 3.2 Validation (update-batch)
+
+1. `enabled`: parseable as bool.  
+2. `status_codes`: valid JSON array; each entry `^\d{3}$` or `^\d{3}-\d{3}$`; expanded values all in 400–599; non-empty when enabled.  
+3. `html`: length ≤ 256 KiB (bytes); empty allowed.  
+4. Parse/expand logic is a **pure function** shared by the API and `pkg/render/openresty` to avoid semantic forks.
+
+No XSS sanitization on HTML: it's an admin global ops config consistent with public edge display; docs warn not to embed untrusted third-party scripts.
+
+### 3.3 Config Version Snapshot
+
+`ConfigSnapshot` adds fields:
+
+```text
+OriginErrorPageEnabled     bool
+OriginErrorPageStatusCodes []string  // raw tags
+OriginErrorPageHTML        string    // empty => renderer uses built-in default
+OriginErrorPageGetOnly     bool
+```
+
+Read from Option when building the snapshot; the Agent only consumes the snapshot, never reading the control-plane DB directly.
+
+---
+
+## 4. Edge Rendering
+
+### 4.1 Content Generated When Enabled
+
+1. **SupportFile**: error page template (e.g. `error_pages/origin_error.html.tmpl`), content is the custom HTML or built-in default, keeping `{{status}}` / `{{host}}`.  
+2. **Each reverse proxy server** (HTTP/HTTPS proxy; excluding Pages):
+
+```nginx
+proxy_intercept_errors on;
+error_page <expanded codes...> @__openflare_origin_error;
+
+location @__openflare_origin_error {
+    default_type text/html;
+    charset utf-8;
+    content_by_lua_block {
+        # read template, replace {{status}} / {{host}}, output body
+        # ngx.status keeps the original error code
+    }
+}
+```
+
+### 4.2 Runtime Replacement
+
+Use a **named location with `content_by_lua_block`** to read the template and replace placeholders — the status is **not** baked into a static file (status differs per request). GET-only mode uses `header_filter_by_lua_block` + `body_filter_by_lua_block` inside the reverse proxy location to replace only GET response bodies; non-GET requests pass through.
+
+Never rewrite the error page to HTTP 200.
+
+### 4.3 When Disabled
+
+Do not output `proxy_intercept_errors`, `error_page`, the internal location, or the corresponding SupportFile (or the file may be written but unreferenced). GET-only mode also omits the Lua filters.
+
+### 4.4 Interaction with Cache / Stale
+
+If global `proxy_cache_use_stale` returns stale cache for some error codes, **successful stale responses never enter `error_page`**. The error page is only shown when the client actually receives an error status in the configured list. Behavior depends on existing cache directives; this feature does not change stale policy.
+
+---
+
+## 5. Frontend
+
+### 5.1 Entry
+
+* Sidebar「Website Management → Response Pages」: Error Page tab (`/responses`), edit page `/responses/error-page/edit`, preview page `/responses/error-page/preview`.  
+
+### 5.2 Page Structure
+
+* Header note: takes effect after releasing via「Version Release」.  
+* **Switch + Tags Input** (shadcn-extension Tags Input: `@/components/ui/tags-input`): status code tags.  
+* **HTML editor area** +「Load default template」「Restore default (clear)」+ placeholder docs.  
+* **Client-side preview**: replace with sample `status=502`, `host=example.com` and preview in sandbox/iframe.  
+* Save: `OptionService.updateBatch`; permissions same as the performance tuning page (admin).  
+
+### 5.3 Component Dependencies
+
+Tags Input and the HTML editor reuse existing shadcn/ui components, consistent with the existing UI style.
+
+---
+
+## 6. Data Flow
+
+```text
+Admin /responses (Error Page tab)
+    → Option update-batch (validate tags & HTML)
+    → w_system_configs
+
+Release config version
+    → snapshot writes OriginErrorPage*
+    → render OpenResty conf + SupportFile
+    → Agent pulls and reloads
+
+Visitor requests a proxied domain
+    → origin/gateway produces a matching status code
+    → error_page → named location
+    → replace placeholders, keep original status, return HTML
+```
+
+---
+
+## 7. Decision Record
+
+| Decision | Choice | Reason |
+| --- | --- | --- |
+| Config scope | global | product requirement; simple implementation and ops |
+| Storage | Option + config version | consistent with performance tuning, rollbackable |
+| Status input | tags: single code and range | default whole 5xx, but can name 522 |
+| Response status | keep original | correct for monitoring/SEO/client semantics |
+| Runtime replacement | internal + lightweight template replacement | status differs per request |
+| Customization | online HTML | flexible without a file-upload chain |

+# Pages Static Hosting Design
+
+You will learn: the architecture design of OpenFlare Pages static hosting, the immutable deployment and secure extraction flow, the OpenResty static serving and API reverse proxy config rendering, and the cooperative workflow between the control plane and the Agent.
+
+---
+
+## Requirements Analysis
+
+In modern web operations, besides reverse proxying dynamic applications, deploying and hosting static frontend sites (SPA apps built with React/Vue, or static generator output like Hugo/VitePress) is extremely common. Traditional approaches suffer from:
+1. **Release disconnected from proxy config**: after uploading frontend build artifacts to the Nginx host, you still need to modify the Nginx vhost config manually or via other scripts — error-prone and without version control.
+2. **Multi-node distribution is hard**: with multiple edge nodes managed by the control plane, syncing static files to all nodes consistently requires complex sync scripts (e.g. rsync).
+3. **Rollback lacks consistency**: once a new frontend package fails or has serious defects, you must restore both the static files and the proxy rules — atomic rollback is hard.
+
+To solve these, OpenFlare introduces **Pages static hosting**, inspired by Cloudflare Pages. It brings "pre-built artifact import" and "website proxy rule config" into the same control plane, leveraging OpenFlare's pull-based cooperative architecture to achieve eventual convergence across multiple Agents via immutable deployments, single-node atomic switching, and periodic reconciliation, with fast rollback.
+
+---
+
+## Core Features
+
+The Pages static hosting subsystem includes:
+* **Pre-built artifact deployment**: upload a static resource archive directly, or save a Remote URL or public GitHub Release asset source for a project. External sources are only accessed by the Server; on successful sync they uniformly create or reuse an immutable deployment and activate it atomically.
+* **Immutable deployment snapshots**: each local upload creates a new candidate deployment; persistent-source sync creates or reuses a deployment by source identity/revision and activates it. All deployments have a unique ID and whole-package SHA-256, support keeping the most recent N historical versions per system config, and can be rolled back anytime.
+* **Check and auto-update**: GitHub latest can be checked periodically per project; by default it only hints at available updates; only after an admin explicitly enables it does it auto-sync and publish by the exact revision found.
+* **SPA Fallback**: supports fallback routing for single-page apps; when a static file isn't found, requests redirect to the entry file.
+* **Built-in API reverse proxy**: enables API proxying within Pages rules with one click, eliminating cross-origin issues by forwarding requests to a designated backend.
+* **Secure package validation and extraction**: built-in path-traversal defense, symlink-hijack protection, file size/count limits, and configurable upload package size control to keep nodes physically safe.
+* **Configurable limits**: admins can adjust the "deployment package size limit" and "historical deployment retention" in ops settings.
+
+### Deployment Sources
+
+Projects currently support three source views: manual, Remote URL, and GitHub Release. No source record means manual; switching or deleting a source doesn't delete historical deployments or change the current active deployment. Remote URL only allows manual "Sync and Publish"; GitHub Release supports manual check/sync for latest/tag, and only latest can opt into scheduled checking and auto-update.
+
+A source is mutable config; a deployment is an immutable fact. Source config and runtime cursor/state/lease are stored separately; deployments only save the security provenance snapshot at creation time. All artifacts reuse the "download or receive artifact → real-byte and entry validation → `upload.Ingest` → deployment" artifact pipeline: manual uploads stop at candidate, waiting for explicit admin activation; persistent-source sync creates-or-loads and atomically activates in the same business transaction.
+
+The admin project detail is organized as "current production deployment → deployment source → deployment history".
+
+---
+
+## Pages Static Hosting Architecture
+
+Pages hosting is logically split into a **Control Plane** and a **Data Plane**.
+
+```mermaid

+    
+    Agent -->|1. discover new version| Server
+    Agent -->|2. download deployment package| Server
+    Agent -->|3. validate, extract, atomic switch| StaticFiles
+```
+
+* **Control Plane**: the Server receives local uploads or fetches Remote/GitHub pre-built artifacts via restricted providers; action tasks and the internal scanner handle checking, syncing, and auto-updates. All artifacts pass unified inspection and `upload.Ingest` into the platform storage backend; manual uploads create a new candidate, persistent-source sync creates-or-loads a deployment and activates it atomically. Config release only compiles the stable project anchor and static serving metadata.
+* **Data Plane**: the Agent discovers Pages projects referenced by config during heartbeat/WS reconciliation, pulls the project's currently active package via a dedicated API, and performs validation and extraction. OpenResty serves static files locally; the Agent doesn't know whether the artifact came from upload, Remote, or GitHub.
+
+---
+
+## Data Model and Metadata Design
+
+### 1. Core DB Entities
+* **Pages project (`of_pages_projects`)**:
+  * Records the business name, Slug (URL-friendly), enabled state, static serving root dir (RootDir, nullable), entry filename (EntryFile, default `index.html`), SPA Fallback settings, and API reverse proxy config (APIProxyPath, APIProxyPass, APIProxyRewrite).
+* **Source config (`of_pages_project_sources`)**:
+  * At most one mutable source config per project, distinguishing Remote URL and GitHub Release by `source_type`. `config_version` fences stale tasks; the full Remote URL lives only in the config table — never in responses, logs, task payloads, or deployment provenance. V2 does not promise DB column encryption.
+* **Source runtime (`of_pages_project_source_runtime`)**:
+  * 1:1 with the source, storing ETag, seen/applied revision, last check/sync, next check, errors, and lease. State is fixed to `idle | checking | update_available | syncing | failed | attention`; queued/completed state is carried by `TaskExecution`.
+* **Pages deployment (`of_pages_deployments`)**:
+  * Records immutable deployment facts: project-incremental deployment number, whole-package SHA-256, `upload_id`, file count/total bytes, creator, and nullable source identity/revision, source security snapshot, and trigger. `artifact_path` is only a legacy-compat field and is no longer the storage truth for new deployments.
+* **Deployment file manifest (`of_pages_deployment_files`)**:
+  * Stores the full regular-file path list and actual byte counts per deployment for console display and statistics.
+  * No longer computes content hashes per file; integrity is guaranteed by the **whole-package** SHA-256 (`of_pages_deployments.checksum`), verified by the Agent when pulling.
+  * Control-plane inspection reads the archive via file handles, streaming each regular file body and checking declared vs actual size — no whole-package `ReadFile` into memory, no per-file disk write for hashing.
+
+### 2. Route Association and Snapshot
+`proxy_routes` rules associate with a Pages project via `upstream_type = "pages"` and `pages_project_id`. A route may join the release flow only when its type is `pages` and the project has an activated deployment.
+The version snapshot emitted at release includes `snapshotPagesDeployment`:
+```json
+{
+  "project_id": 1,
+  "project_slug": "my-spa-app",
+  "deployment_id": 12,
+  "deployment_number": 3,
+  "checksum": "a7b3c2...",
+  "entry_file": "index.html",
+  "spa_fallback_enabled": true,
+  "spa_fallback_path": "/index.html",
+  "api_proxy_enabled": true,
+  "api_proxy_path": "/api",
+  "api_proxy_pass": "http://api.internal:8000",
+  "api_proxy_rewrite": "/api/(.*) /$1",
+  "local_root": "__OPENFLARE_PAGES_DIR__/projects/1/current"
+}
+```
+
+### 3. Dual-Track Relationship with the Main Config Version (project anchor + latest pull)
+* The **main config version** and **Pages deployments** are two independent version systems.
+* The stable anchor of a Pages route in the main config is **`pages_project_id` (project ID)**, not a deployment ID.
+* The OpenResty `root` uses the project-level path `__OPENFLARE_PAGES_DIR__/projects/{project_id}/current`; the path stays unchanged on activation switch, so swapping packages never requires republishing the main config.
+* The Agent requests the "latest active package" per project (like `github/release/latest`):
+  * `GET /api/v1/agent/pages/projects/:project_id/latest/hash`
+  * `GET /api/v1/agent/pages/projects/:project_id/latest/package`
+  * The control plane returns the deployment ID, hash, package size, and expanded manifest metadata for the project's **currently active deployment**. The Agent uses the deployment ID and other latest metadata to detect pointer races during download, but the stable anchor of the main config and local dir remains the project ID.
+* Therefore: switching the active deployment within a project **does not require publishing the main config**; the Agent polls the latest hash during periodic reconciliation, downloads on change, and switches `current`.
+* The `pages_deployment` field in the snapshot still records release-time metadata (entry file, SPA/API proxy, etc.) but does not lock the Agent's package version.
+
+---
+
+## Server (Control Plane) Responsibilities and Lifecycle
+
+### 1. Deployment Package Security Validation and Analysis
+To protect the server from untrusted artifacts, the control plane applies the same strict validation to local uploads and all external sources:
+* **Format support**: `zip`, `tar.gz` / `tgz`, `tar.xz` / `txz`, `tar.bz2` / `tbz2`, `tar`, `7z`.
+* **Size limits**: archive size is controlled by system config `pages_max_package_size_mb` (default 100 MiB, range 1–2048); expanded single-file and total limits are "package size × 4" with a floor of 100 MiB. Inspection always streams regular file bodies, checking declared vs actual size and enforcing limits on actual values.
+* **Count limit**: at most 1,000 static files per package.
+* **Symlink blocking**: any symlink detected while walking the archive immediately errors and rejects the upload, defending against symlink-hijack attacks.
+* **Path traversal defense**: every archive file path is `Clean`ed and checked for `..` or leading `/`, defending against directory-traversal writes to sensitive system paths.
+* **Entry file validation**: the project's entry file (e.g. `index.html`, possibly under `project.RootDir`) must exist in the package, otherwise the upload is rejected.
+* **Common root prefix stripping**: many packaging tools add a redundant top folder as a common root prefix; the control plane auto-detects and safely strips it.
+* **Whole-package integrity**: SHA-256 is computed once over the archive bytes at upload/import and written to the deployment record; the Agent reconciles against the whole-package hash after pulling. No per-file content hashes.
+* **Actual size recheck**: `InspectOptions.VerifySizes` is kept only for compatibility; current inspection always reads regular file bodies, checks declared values, and accumulates actual sizes, but still does not compute per-file content hashes.
+* **History retention**: system config `pages_max_history_count` (default 20; 0 = unlimited) trims after successful deployment. Semantics: **each project keeps at most N deployments**; the currently active deployment is always kept, remaining slots fill from newest to oldest by deployment ID. With `history_count=1`, manual uploads temporarily keep both the active and the newest candidate; the next upload replaces the old candidate; after the candidate activates, the strict limit resumes. Exceeding non-active deployments and their file manifests are deleted; the corresponding upload record is soft-deleted idempotently via platform primitives — Pages never physically deletes blobs that may be shared by dedup. If trimming fails after a successful deployment, it only logs and doesn't roll back activation; concurrent operations may temporarily exceed N and converge on later trims. Main config version rollback does not depend on old Pages packages (see the dual-track section above).
+
+### 2. Deployment Package Storage Planning
+The control plane stores local, Remote, and GitHub artifacts into the configured local/S3 backend via the unified upload framework (`upload.Ingest`), recording `upload_id` and the file manifest in the DB. **Large static packages never enter `config_versions` records or any config push channel**, keeping control-plane data sync lightweight.
+
+### 3. Source Check, Auto-Update, and Upload Compensation
+
+* `openflare:pages_source_action` executes admin check/sync or scanner-dispatched exact-revision sync; payloads never carry URL, Token, ETag, or lease tokens. Manual sync only accepts real user actors; auto sync only accepts the system actor with the `scheduled_auto_update` trigger.
+* `openflare:pages_source_scan` is a fixed `*/5 * * * *` internal-only TaskHandler accepting only `{}`; it never appears in generic task types or the schedule management UI. Each round runs "recover expired leases → compensate orphan uploads → scan due sources".
+* The scanner sorts stably by `next_check_at, source_id`, serially checking at most 20 GitHub latest sources per batch; ETag/304 still advances the check time; 403/429 record the status code and the actual backoff deadline; a single source failure doesn't block subsequent sources.
+* On finding an update, the seen cursor is always saved first. Only with `auto_update_enabled=true` and a normal `update_available` state does it dispatch sync with the exact revision found this check; `attention`, Remote, and fixed tags never auto-publish. Manually activating another deployment fences in-flight tasks and disables auto.
+* Orphan compensation checks at most 100 upload records per round that have been quarantined for at least 2 hours, requiring a system owner, Pages retention type, V2 marker, and no deployment references. Candidates are re-checked in the `project → source → runtime → upload` lock order and only soft-deleted via the upload framework with stat updates — never physically deleting blobs possibly shared by dedup.
+
+---
+
+## Agent (Data Landing) Responsibilities and Self-Healing
+
+The Agent runs on each edge proxy node: on first applying config referencing a Pages project, and on subsequent periodic latest reconciliation, it "atomically" pulls the currently active static assets to the node.
+
+### 1. Pull Latest Per Project
+1. The Agent parses routes with `UpstreamType == "pages"` from the active main config and collects the stable anchor **`pages_project_id`**.
+2. For each project it calls `GET /api/v1/agent/pages/projects/:project_id/latest/hash` to get the control plane's currently active package hash (a latest pointer).
+3. If the local `projects/{project_id}/releases/{hash}` isn't ready, it streams `.../latest/package` to a temp file, enforcing real response limits and SHA-256; after download it **requests the hash again** to avoid activation-switch races, retrying a bounded number of times on mismatch.
+4. The request carries the node's `X-Agent-Token`.
+
+### 2. Secure Extraction, Atomic Switch, Keep Only Latest
+1. Absolute package cap is 2 GiB; the downloaded content's SHA-256 must match the latest hash from the post-download re-query; the whole package never enters `[]byte`.
+2. Extract into a random staging dir `projects/{project_id}/releases/.{hash}-<random>.tmp` (zip / tar.* / 7z supported), rejecting path traversal, links, and special files. The Agent obeys both Server metadata limits and local absolute limits: at most 1,000 files, single file and total at most 8 GiB.
+3. After extraction, walk the actual file tree and precisely recheck file count and total bytes against the Server metadata; mismatch → refuse to switch.
+4. Write `.openflare-pages.json`, then rename to `releases/{hash}`.
+5. **Atomic switch** `projects/{project_id}/current` to the new release (symlink preferred, copy on failure).
+6. **Only after the new package is ready and current has switched successfully**, delete other `releases/*` (including `.tmp`) under the project — **historical deployment packages are never kept on the edge**. Each project always keeps exactly one latest content per node.
+7. Multi-project reconciliation **isolates failures**: a single project failure logs and continues with others, finally aggregating errors.
+
+---
+
+## OpenResty (Static Serving and Proxy) Config Rendering
+
+For Pages-hosted sites, the control plane renders the corresponding `server` block, replacing the regular proxy route's `proxy_pass`.
+
+### 1. Static Serving Directive Rendering
+* **`root` and `index`**:
+  The Server points `root` at the project-level placeholder path `__OPENFLARE_PAGES_DIR__/projects/{project_id}/current` (optionally appending `RootDir`). Activation switching only changes directory contents, not the path, so swapping packages never requires republishing the main config.
+  ```nginx
+  server {
+      listen 80;
+      server_name myapp.example.com;
+      
+      root "/var/lib/openflare/pages/projects/3/current";
+      index "index.html";
+      ...
+  }
+  ```
+
+### 2. try_files and SPA Fallback
+* **SPA Fallback disabled (default)**:
+  only match physically existing files, otherwise strict 404:
+  ```nginx
+  location / {
+      try_files $uri $uri/ =404;
+  }
+  ```
+* **SPA Fallback enabled**:
+  if the requested file doesn't exist, redirect to the project's configured entry fallback (usually `/index.html`):
+  ```nginx
+  location / {
+      try_files $uri $uri/ /index.html;
+  }
+  ```
+
+### 3. API Reverse Proxy and Rewrite Rendering
+When a static frontend needs backend API access without cross-origin issues, enable the API proxy. The OpenResty renderer nests a dedicated API `location` branch inside the static `server` block:
+```nginx
+server {
+    listen 80;
+    server_name myapp.example.com;
+    ...
+    # API proxy path match
+    location /api {
+        # apply rewrite rules when configured
+        rewrite ^/api/(.*)$ /v1/$1 break;
+        rewrite ^/api$ / break;
+
+        proxy_pass http://api.internal:8000;
+        proxy_http_version 1.1;
+        proxy_set_header Host $http_host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto $scheme;
+        proxy_set_header Upgrade $http_upgrade;
+        proxy_set_header Connection $connection_upgrade;
+    }
+
+    location / {
+        try_files $uri $uri/ /index.html;
+    }
+}
+```
+
+---
+
+## Interaction Logic and Sync Flow
+
+A full pre-built artifact import and activation lifecycle looks like this. Binding a project for the first time requires publishing the main config; subsequent active deployment changes converge independently via the project latest:
+
+```text
+  [Admin / scanner]       [Server control plane]        [Agent]                  [OpenResty]

+# Tunnel & Intranet Penetration Design
+
+You will learn: the architecture design of OpenFlare's intranet penetration tunnels, the internal principles of the dual-end control components (Relay and Client), interaction logic, and the data-plane / control-plane communication flows.
+
+---
+
+## Requirements Analysis
+
+In typical web-hosting scenarios, many origins are deployed in intranet environments (local dev machines, LAN servers, or firewall-restricted intranet clusters). These servers usually:
+1. **Have no public IP**: cannot be directly reached by public traffic.
+2. **Compliance restrictions**: port mapping (NAT) on border routers is not freely allowed.
+3. **Dynamic IP changes**: traditional DDNS is high-latency and unstable.
+
+To let intranet origins seamlessly join the OpenFlare global data gateway and enjoy value-added services like WAF geo protection and TLS certificate management, OpenFlare designs a **reverse-relay tunnel penetration** solution. In this architecture, public edge nodes act as the reverse-proxy entry and traffic relay; the intranet side only needs outbound secure connections to safely and stably reverse-penetrate public traffic to intranet origins.
+
+---
+
+## Core Features
+
+The intranet penetration subsystem includes:
+
+* **Dynamic Relay node management**: the control plane dynamically dispatches the relay service (frps), dynamically distributing service ports and auth tokens.
+* **Multi-tunnel reverse proxy mapping**: map multiple intranet web ports on a single intranet client, binding multi-domain routes to corresponding relay nodes.
+* **Independent process lifecycle management**: both relay and client are standalone Go binaries that spawn, monitor, self-heal, and hot-upgrade the underlying frp engines.
+* **Token-based auth isolation**: the relay uses `agent_token`; the intranet client uses its dedicated `tunnel_token` — permissions and route boundaries isolated.
+* **Config validation and incremental hot reload**: config files are rewritten and processes reloaded only when tunnel bindings, certificates, or Relay topology actually change, reducing runtime overhead.
+
+---
+
+## Tunnel Architecture
+
+The subsystem integrates the mature `frp` high-performance tunnel protocol, split into a **Control Plane** and a **Data Plane**.
+
+```mermaid

+
+    RelayManager -.->|manage process & config| RelayFrps
+    ClientManager -.->|manage multiple Relay processes| FlaredFrpc
+```
+
+* **Control Plane**: the Server maintains DB state; `openflare-relay` on relay nodes and `openflared` on intranet servers sync tunnel config via HTTP heartbeats and WebSocket long channels.
+* **Data Plane**: public traffic first enters the public-edge Agent (OpenResty), where HTTPS handshake, TLS termination, and WAF filtering happen; then `proxy_pass` forwards to the same-host `openflare-relay (frps)`. `frps` encapsulates the request and sends it through the persistent tunnel established with the intranet `openflared (frpc)`, which finally unpacks and dispatches to the actual intranet origin.
+
+---
+
+## Relay Design
+
+`openflare-relay` is the relay manager deployed at the public edge, running on `tunnel_relay`-type nodes.
+
+### 1. Core Architecture & Logic
+* **Process guard**: the Relay process holds the `frps` binary, spawns `frps -c frps.toml` via `exec.Command`, and starts a goroutine asynchronously watching its exit state. If `frps` exits abnormally, it auto-restarts with backoff.
+* **Dynamic config rendering**: syncs state to the control plane via HTTP heartbeat and fetches the current `RelayConfig`, mainly:
+  * `bindPort`: frps's public control port listening for intranet frpc client connections.
+  * `vhostHTTPPort`: vhost HTTP traffic port; the Agent's proxy_pass points here.
+  * `authToken`: security credential for client handshake validation.
+  * `webServer`: enables the frps dashboard API; the Relay collects real-time active tunnel counts and traffic metrics from this or the admin control port.
+* **State reporting**: each heartbeat reports the underlying `frps` active connections, registered client count, per-proxy real-time state, and Relay version.
+
+---
+
+## Openflared (Client) Design
+
+`openflared` is the client manager on the user's intranet server, authenticated with its dedicated `tunnel_token`.
+
+### 1. Core Mechanisms
+* **Multiple Relay support (multiplexing)**:
+  for HA or nearest access, the control plane may schedule a client across multiple public Relays. `openflared` reads the Relays list in `TunnelConfig`, generates a dedicated config per Relay locally (named `frpc_<relay_node_id>.toml`), and assigns each Relay process an independent cancelable context.
+* **Independent child-process monitoring**:
+  `openflared` maintains a `processes` map for per-`frpc` lifecycle management. When the control plane adds or removes a Relay, the client incrementally spawns new processes or gracefully shuts down old ones without affecting other working tunnels.
+* **Dynamic TOML generation**:
+  when rendering the TOML for each Relay, the client iterates the Proxies list and writes each intranet service's `LocalAddr`, `LocalPort`, and bound `CustomDomains` into `[[proxies]]` blocks.
+
+---
+
+## Interaction Logic and Traffic Model
+
+The subsystem implements consistent versioning and state feedback.

+2. **Apply-result loop**: after applying new config, the client reports the result in its heartbeat. If frpc can't connect (intranet port unreachable or wrong cert config), the client captures process output and reports `LastError`, letting admins see penetration failure reasons directly in the Server.

+   ```nginx
+   server {
+       listen 443 ssl;
+       server_name intranet.example.com;
+       # ... TLS cert & WAF filtering logic ...
+       location / {
+           proxy_pass http://127.0.0.1:8080; # points to the local frps vhost port
+           proxy_set_header Host $host; # must keep the original Host; frps routes by Host
+           proxy_set_header X-Real-IP $remote_addr;
+       }
+   }
+   ```
+2. **Relay node (frps)**:
+   `frps` receives the HTTP request on the vhost port (default `8080`), reads the `Host: intranet.example.com` header, and looks up the registered active-tunnel table for the matching encrypted TCP connection (established by the intranet frpc).
+3. **Encrypted tunnel transport (TCP)**:
+   `frps` encapsulates the HTTP request into the internal TCP tunnel protocol and sends it to the intranet `frpc` client.
+4. **Intranet client dispatch (frpc)**:
+   the `frpc` managed by `openflared` receives the packet, opens a local TCP connection per local config (`localIP = "127.0.0.1"`, `localPort = 8080`), forwards to the intranet web service, and returns the response along the same path to the public user.

+# WAF Design
+
+OpenFlare's current WAF rule model is a visual DAG. Node semantics, graph constraints, multi-rule ordering, release compilation, and migration boundaries are all governed by [WAF Orchestration Rule Design](./waf-orchestration-design.md).
+
+## System Boundaries
+
+The Server stores the edit graph with coordinates and a revision number; at release it re-validates and compiles it into a compact runtime graph; the Agent atomically writes the snapshot and reloads OpenResty; the request hot path only traverses the immutable in-memory graph in the Worker.
+
+IP groups update independently of rule topology. Manual, subscription, and auto IP groups are maintained by the control plane; the Agent atomically replaces the JSON first and updates the checksum last. A coordinating worker checks the checksum every 5 seconds, reading and distributing the full snapshot only on change; on failure it keeps the previous valid data. The full runtime snapshot is capped at 20 MiB; Server release/sync and Agent disk writes use the same serialization validation; OpenResty uses a separate 64 MiB shared dict with non-evicting writes, refusing new versions on capacity shortage without breaking committed snapshots.
+
+Geo nodes use Country and City MMDB. Docker images bundle the database files; bare-binary installs have the Agent download missing files at first startup and update them periodically per config; request handling always reads the DB already loaded by OpenResty. When the DB is unavailable, geo match returns `false` with a rate-limited warning; other execution errors must not be accidentally allowed through due to data corruption.
+
+## Security Ordering
+
+Enabled global rules always run first; route rules execute by binding sequence. A block node terminates immediately; a pass node only ends the current rule; only after all rules pass does traffic enter the origin chain. Unknown nodes, missing outlets, or step-limit overruns always block the request.

+# WAF Orchestration Rule Design
+
+This document defines the target architecture, data model, execution semantics, release model, and migration boundaries for reworking OpenFlare WAF from a fixed decision chain into a visual directed acyclic graph (DAG). IP group sources and membership computation still follow [WAF Design](./waf-design.md); this document only changes how rules are composed and executed.
+
+## Goals and Boundaries
+
+When a user adds a WAF rule, they only enter a name. The Server immediately creates a legal default graph `start → pass`, and the frontend enters a standalone orchestration page based on React Flow. Users build policies by adding processing units, configuring nodes, and connecting branches — no more filling in fixed-order allow/block lists and PoW forms.
+
+Supported nodes:
+
+| Node | Count Constraint | Inputs | Outputs | Config |
+| --- | --- | --- | --- | --- |
+| Start | exactly one per graph | none | `next` | none |
+| Pass | exactly one per graph | one or more | none | none |
+| Block | multiple allowed | one or more | none | HTTP status code, HTML response body |
+| IP match | multiple allowed | one or more | `true`, `false` | IP, CIDR, IP group ID |
+| Geo match | multiple allowed | one or more | `true`, `false` | country code, region code |
+| UA check | multiple allowed | one or more | `true`, `false` | UA required, browser/OS allowlist with and/or, block crawlers/abnormal UAs (excluding crawlers)/custom regex |
+| Security | multiple allowed | one or more | `true`, `false` | basic signature detection (path traversal/file inclusion on by default; SQL/XSS/command injection/SSRF/upload/XXE/CRLF toggleable); any enabled rule hit → false |
+| PoW | multiple allowed | one or more | `next` | algorithm, difficulty, session TTL, challenge TTL |
+
+IP match, geo match, UA check, and security do not distinguish allowlist vs blocklist. `true` only means the request passed that node's judgment; `false` only means it did not; the business meaning of allow vs block is entirely determined by the wiring. UA check evaluation order: require UA → block crawlers/abnormal UAs → allowlist match. Security performs signature matching on the request Path/Query/Header/Cookie/Body (bounded). After PoW verification succeeds, execution continues along `next`; when incomplete, the challenge page takes over the request and no `false` branch is produced.
+
+Loops, script nodes, arbitrary expression nodes, subgraph calls, and cross-rule jumps are not implemented.
+
+## Control-Plane Architecture
+
+The rule graph uses a dual model separating control-plane edit state and data-plane runtime state:
+
+1. The React Flow editor submits a versioned graph JSON containing node IDs, node types, display names, coordinates, typed configs, and edges.
+2. The Server performs authoritative validation of the whole graph; on success it saves the graph in a single transaction and increments the revision number.
+3. On config release, the Server validates all enabled rules again, compiles the graph into a compact runtime DAG without UI fields (coordinates, labels, etc.), and collects the referenced IP group IDs.
+4. The Agent atomically writes the full release snapshot and reloads OpenResty. New Workers only load and parse the rule JSON once at startup.
+5. The request hot path only traverses the immutable in-memory runtime graph in the Worker — no file reads, no checksum computation, no JSON parsing.
+
+The edit-state JSON uses an explicit `schema_version`. Node configs use per-node-type structures; unconstrained key-value objects bypassing Server validation are not allowed. Initial safety limits: 128 nodes, 256 edges, and 256 KiB of edit-state JSON per rule; these limits are enforced by both the API and the release compiler.
+
+## Graph Structure Constraints
+
+Rule save and release must satisfy all constraints:
+
+* The graph is a DAG; self-loops and arbitrary cycles are forbidden.
+* Exactly one start node and one pass node exist; multiple block nodes are allowed.
+* The start node has no incoming edges and exactly one `next` outlet; pass and block nodes have no outlets.
+* IP match, geo match, UA check, and security must each connect their `true` and `false` outlets once; PoW's `next` must connect once.
+* No dangling outlets except terminal nodes; every non-start node has at least one incoming edge.
+* All nodes must be reachable from start, and every executable node must be able to reach pass or block.
+* Edge source ports must belong to the source node type; the same source port must not connect to multiple targets.
+* Node IDs are unique within the graph, edge IDs are unique within the graph, and all referenced nodes must exist.
+* Node configs must pass per-type field, range, reference-existence, and size validation.
+
+The frontend provides instant validation and connection restrictions to improve UX, but the Server is the only authoritative validator. When deleting a node, the frontend synchronously removes related edges and marks the rule unsaved; saving is forbidden until the graph is legal again.
+
+## Multi-Rule Execution Semantics
+
+A route can bind multiple custom rules. The binding is an ordered list following this order:
+
+1. Enabled global rules always execute first and do not participate in route-side ordering.
+2. Enabled rules bound to the route execute in binding order.
+3. When the current rule reaches a block node, it immediately outputs that node's configured response and terminates the request.
+4. When the current rule reaches a pass node, that only means the current rule finished; if more rules remain, execution continues.
+5. Only after all rules reach a pass node is the request truly allowed to proceed into the OpenResty/origin chain.
+
+The runtime graph is fully validated before release. If the Lua executor still encounters an unknown node, unknown port, missing target, or exceeds the node-step limit, it logs a rate-limited error and blocks the request, preventing a broken security config from accidentally allowing traffic.
+
+## IP Group Memory Refresh
+
+Rule topology only takes effect on release + OpenResty reload; IP group membership can still be updated independently by manual, subscription, or auto tasks without release or reload.
+
+IP groups use a two-level cache of coordinating worker, shared snapshot, and worker-local objects:
+
+1. Requests always read the IP group object in the current worker's memory — no file access or shared-dict JSON parsing.
+2. Every 5 seconds only one worker holding a shared lock reads the lightweight checksum file.
+3. If the checksum is unchanged, it ends immediately without reading the full `waf_ip_groups.json`.
+4. On checksum change, the coordinating worker reads and validates the full JSON once, writes the raw snapshot to a dedicated 64 MiB `ngx.shared.openflare_waf_ip_groups` keyed by checksum, then updates the commit pointer.
+5. Other workers detecting a shared version change fetch the snapshot from shared memory, parse it, and atomically replace their local object — no repeated disk reads.
+6. On refresh failure, keep using the previous valid object, log a rate-limited error, and retry next cycle.
+
+The Agent must atomically replace the IP group JSON first, then atomically update the checksum last, so workers never recognize a half-written file as a new version. Server release/sync and Agent disk writes jointly enforce the 20 MiB aggregate snapshot limit; shared dict uses a safe write that never force-evicts old keys, keeping the current and previous immutable snapshots on failure.
+
+## API and Editor
+
+The create API only accepts a rule name and returns the rule detail with the default graph. Rule metadata, graph save, and route binding use separate operations, so toggling enabled state or binding does not overwrite the canvas.
+
+The graph detail includes `revision`. Save requests submit `revision + graph`; the Server only updates and increments the revision when it matches. On mismatch it returns a conflict, the frontend prompts a reload, and silent overwrites of another page's changes are forbidden. The route binding API accepts an ordered array of rule IDs.
+
+The React Flow editor page uses a full-width canvas and a fixed right property panel:
+
+* Top bar: back, rule name, enabled state, validation state, and save.
+* The canvas uses compact height with a smaller initial fit scale; zoom, pan, box-select, delete, auto-layout, MiniMap/Controls and other necessary navigation are supported. Node dragging is handled by React Flow's local controlled state in real time; coordinates are written back to the edit graph only after the drag ends.
+* "Add processing unit" offers IP match, geo match, UA check, security, PoW, and block; start and pass are provided by the default graph and cannot be deleted or duplicated.
+* Selecting a normal node or edge allows deletion via the canvas delete button or Delete/Backspace; deleting a node synchronously removes associated edges.
+* The right property panel is hidden by default, shown only when a node is selected; it collapses when clicking an edge or blank canvas.
+* Geo-match properties use the full country and ISO 3166-2 first-level administrative division data; country options show both localized names and codes; administrative divisions support search by country name, division name, or code to avoid rendering thousands of options at once.
+* Leaving the page with unsaved changes must prompt; save conflicts and Server validation errors should locate the relevant node or edge.
+
+The WAF list shows rule name, enabled state, node count, bound route count, and update time. The new-rule dialog only has the name field and navigates to the orchestration page immediately on success.
+
+## Persistence and Migration
+
+Rule records add a versioned graph JSON and a revision number; binding records add execution order. The graph is saved as a single aggregate (not split into node/edge tables) to keep edit operations transactional and let new node types avoid frequent DB schema extensions.
+
+When upgrading existing installs:
+
+* Keep rule names, global flags, enabled state, and route bindings.
+* All rule graphs reset to `start → pass`; legacy IP/geo lists, PoW, or block-response configs are not migrated.
+* Existing bindings are written into the order field in a stable sequence; global rules remain fixed in front.
+* Once the new graph and runtime stabilize, remove the legacy rule fields, fixed-order compile logic, and old frontend forms — do not maintain dual executors long-term.
+
+This migration stops the old protection config from taking effect; the upgrade notes must prominently tell admins to re-orchestrate rules before releasing the next version.
+
+## Release, Failure, and Rollback
+
+Rule graphs only take effect on config release. If validation or compilation fails before release, the release is refused and the current active version stays unchanged. If Agent write, OpenResty config check, or reload fails, the apply flow fails and restores the previous valid released version.
+
+New workers only accept complete, parseable runtime rule configs. During an OpenResty graceful reload, old workers keep the old in-memory graph and new workers use the new graph, so requests never observe a half-updated state.
+
+When the geo database is unavailable, geo match returns `false` with a rate-limited warning, preserving current behavior. On IP group refresh failure, the old in-memory snapshot is kept. An incomplete PoW is taken over by the challenge module, not treated as an execution error; PoW node config is first written to OpenResty shared memory with a short-lived key, then passed to the internal challenge handler via explicit `ngx.exec` parameters — it cannot rely on internal redirects preserving `ngx.ctx` or implicitly inherited request params. Empty rule bindings in the release snapshot must be encoded as JSON empty arrays; at runtime, legacy `null` optional arrays in old snapshots are treated as empty arrays, so `cjson`'s `ngx.null` userdata never breaks the request.

+# Zone & Domain Resource Design
+
+## Goals
+
+Refactor "websites" into a Zone management experience keyed by registrable root domains. A Zone like `example.com` is a stable management boundary; users enter the Zone through a stable ID path to view and maintain its explicitly declared domains, the reverse proxy routes and certificates bound to those domains, and route-level WAF, Pages and other capabilities.
+
+This design replaces the concept, tables, and APIs of `managed_domains`. The Zone core does **not** include authoritative DNS record management; to point ZoneDomain A records at edge nodes, use the optional module [Cloudflare DNS Pointing](./cloudflare-pointing.md).
+
+## Scope and Constraints
+
+* Zone root domains are resolved with the Public Suffix List, e.g. `api.example.co.uk` belongs to `example.co.uk`.
+* URLs use IDs: list at `/websites`, detail at `/websites/:zoneId`; domains are not used as URL parameters.
+* Zone domains must be explicit FQDNs; `*.example.com` is not allowed. TLS certificates may still contain wildcard SANs and cover explicit Zone domains.
+* A Zone domain is associated with at most one reverse proxy route; a route may associate with multiple Zone domains, thus sharing the same upstream, cache, rate limit, WAF and Pages config across Zones.
+* The Zone model itself adds no DNS records, edge functions, preview subdomains, or tenant isolation. Creating/updating external DNS A records is handled by the separate Cloudflare pointing module and does not change the Zone / ZoneDomain table responsibilities.
+
+## Core Model
+
+```mermaid
+erDiagram
+  ZONES ||--o{ ZONE_DOMAINS : contains
+  PROXY_ROUTES ||--o{ ZONE_DOMAINS : serves
+  TLS_CERTIFICATES ||--o{ ZONE_DOMAINS : secures
+  PROXY_ROUTES ||--o{ WAF_RULE_GROUP_BINDINGS : applies

+    uint id PK
+    uint zone_id
+    uint proxy_route_id
+    string domain UK
+    uint cert_id
+  }
+```
+
+### `of_zones`
+
+Stores the root domain, created time, and updated time. Root domains are globally unique and cannot be modified in place after creation; to change one, create a new Zone and migrate the domains. Before deleting a Zone, all of its Zone domains must be cleared first.
+
+### `of_zone_domains`
+
+Stores `zone_id`, explicit `domain`, nullable `proxy_route_id`, nullable `cert_id`, and timestamps. `domain` is globally unique; all relationship fields are indexed but no physical foreign keys are created. `proxy_route_id` may be null to host historical domains that have a certificate prepared but no reverse proxy configured yet.
+
+`of_proxy_routes` gradually removes the domain/certificate redundancy columns `domain`, `domains`, `cert_id`, `cert_ids`, and `domain_cert_ids`. Routes must no longer specify any TLS certificate; the route name `site_name` becomes the stable human-readable identifier, and the compiler reads `server_name` and its `cert_id` from the associated Zone domains. This gives each explicit domain a single certificate source.
+
+## Business and API
+
+New Zone resources in the admin panel:
+
+* `GET/POST /api/v1/d/zones`
+* `GET/POST /api/v1/d/zones/:id/update`
+* `POST /api/v1/d/zones/:id/delete`
+* `POST /api/v1/d/zones/:id/domains` (list returned via overview)
+* `POST /api/v1/d/zones/:id/domains/:domainID/update`
+* `POST /api/v1/d/zones/:id/domains/:domainID/delete`
+* `GET /api/v1/d/zones/:id/overview`
+
+Reverse proxy route create/update requests switch to `zone_domain_ids` and no longer submit `domains`, `cert_id`, `cert_ids`, or `domain_cert_ids`. The server validates domain ownership, global uniqueness, and certificate SAN coverage in a transaction; failures are returned uniformly via `response.Abort*`. Deleting a Zone domain bound to a route requires unbinding or deleting the route first; deleting a Zone that still has domains must be rejected.
+
+WAF, Pages, upstream, and release versions remain part of `proxy_routes`. The Zone overview only aggregates the route state associated with its domains and does not copy or redefine those configs.
+
+## Frontend Experience
+
+`/websites` shows only Zone root domains with configured domain count, route count and status, plus search, create, and action menus. Clicking enters `/websites/:zoneId`.
+
+The detail page includes:
+
+* Overview: domain, route, and valid certificate statistics; domain—route—certificate summary; route-level WAF and Pages summary.
+* Domains: a list of explicit FQDNs, certificate selection, and associated routes; wildcard domains are not shown or accepted.
+* Routes: routes filtered to the current Zone, linking to existing route details.
+* Certificates: certificates actually referenced by the current Zone's domains.
+* Settings: Zone notes and a protected delete operation.
+
+When adding a route, select from Zone domains; users can also register domains in the Zone first, then bind a route. The global reverse proxy route entry remains but uses the same Zone domain selector.
+
+## Data Migration
+
+This rework ships in two release phases to avoid SQL using a wrong "last two labels" rule for multi-level public suffixes. Operation details: [Zone Domain Migration and Release Acceptance](../guide/zone-domain-migration.md).
+
+1. **Phase 1 DDL**: PostgreSQL and SQLite goose create `of_zones` / `of_zone_domains` at the same version; `of_managed_domains` and route redundancy columns are temporarily kept.
+2. **Data import (automatic)**: at Server startup `migrator.Migrate()` first applies goose SQL up to `202607120002`, then automatically imports legacy route domains / `managed_domains` (registering root domains via `publicsuffix` parsing, writing `cert_id` and `proxy_route_id`), then continues with the remaining SQL. Conflicts fail startup; fixing and restarting retries idempotently. No manual command needed.
+3. **Code switch**: control-plane APIs, config snapshots, rendering, and frontend all use Zone domains as the single source; route writes only use `zone_domain_ids`.
+4. **Phase 2 cleanup**: goose SQL `202607130001_drop_legacy_route_domain_columns` drops `of_managed_domains` and the `of_proxy_routes` redundancy columns. Down only restores an empty dev-DB structure and does not backfill historical data.
+
+### Runtime Model Boundaries
+
+* Persistence: domains and certificates exist only in `of_zone_domains`; `of_proxy_routes` only stores route policy (upstream, cache, rate limit, WAF binding keys, etc.).
+* Rendering: the config snapshot assembles temporary `Domains` / `DomainCertIDs` in memory for OpenResty rendering and does not write back to the database.
+* Structure migration only uses `internal/infra/persistence/migrator/goose/{postgres,sqlite}/*.sql`; legacy domains are imported automatically at startup, and after phase 2 the old columns no longer exist so it is a no-op.

+# TLS Certificates and Auto-Renewal
+
+This guide explains how to manage TLS certificates in OpenFlare. To secure traffic with HTTPS, you need to configure the corresponding certificate. OpenFlare supports **manually importing existing certificates** and **automatic issuance and managed renewal via ACME**.
+
+---
+
+## Method 1: Manually Import an Existing Certificate
+
+If you have obtained a free or paid certificate from a third-party provider (such as Tencent Cloud, Alibaba Cloud, etc.), or generated a self-signed certificate locally:
+
+1. Log in to the admin panel, go to **「Website Management」->「TLS Certificates」** in the left navigation.
+2. Click **「Import Certificate」** in the top-right corner.
+3. Fill in the configuration:
+   * **Certificate Name**: Enter an easily recognizable alias (e.g. `my-domain-cert`).
+   * **Certificate Content (PEM)**: Paste the PEM-format certificate public key (usually starts with `-----BEGIN CERTIFICATE-----`).
+   * **Private Key (KEY)**: Paste the certificate private key (usually starts with `-----BEGIN PRIVATE KEY-----` or `-----BEGIN RSA PRIVATE KEY-----`).
+4. Click **「Save」**. After a successful import, the certificate can be directly bound when configuring domains.
+
+---
+
+## Method 2: Automatic Issuance and Auto-Renewal (ACME)
+
+OpenFlare has a built-in ACME client integrated with the **Asynq async task queue**. With the DNS API of your cloud DNS provider, the system can automatically complete DNS-01 challenge validation, apply for wildcard/single-domain certificates from a CA (Let's Encrypt by default), and **automatically trigger renewal 7 days before expiry**.
+
+### Step 1: Create a DNS API Token in Cloudflare
+
+To let OpenFlare automatically add TXT records under your domain for DNS validation, you need a Cloudflare API Token with specific permissions.
+
+> [!IMPORTANT]
+> For security, **it is strongly recommended to use a permission-scoped API Token** rather than the Global API Key.
+
+1. Log in to the [Cloudflare dashboard](https://dash.cloudflare.com/).
+2. Click the user avatar in the top-right corner and select **「My Profile」**.
+3. In the left menu select **「API Tokens」**, then click **「Create Token」**.
+4. Find the **「Edit Zone DNS」** template and click **「Use template」**.
+5. Configure the token permissions and scope (keep defaults or restrict as needed):
+   * **Permissions**:
+     * `Zone` - `DNS` - `Edit` (required, for ACME to write TXT records)
+     * `Zone` - `Zone` - `Read` (required, to list and retrieve zone IDs)
+   * **Zone Resources**:
+     * Select **「Include」** -> **「All zones」**, or select **「Specific zone」** and point to the specific domain you manage.
+6. Click **「Continue to summary」**, confirm, then click **「Create Token」**.
+7. Copy the generated **API Token** string. It is only shown once, so save it carefully.
+
+### Step 2: Add a DNS Account in the Control Plane
+
+1. Log in to the OpenFlare admin panel, go to **「Website Management」->「DNS Accounts」**.
+2. Click **「Add Account」**.
+3. Fill in the configuration:
+   * **Account Name**: e.g. `cloudflare-main`.
+   * **DNS Provider**: Select `Cloudflare`.
+   * **API Token**: Paste the API token copied from Cloudflare (stored encrypted automatically).
+4. Click **「Save」**.
+
+### Step 3: Submit a Certificate Application Task
+
+1. Go to **「Website Management」->「TLS Certificates」**, click **「Apply for Certificate」** in the top-right corner.
+2. Fill in the application form:
+   * **Certificate Name**: Custom name (e.g. `wildcard-example-cert`).
+   * **Primary Domain**: The domain to apply for (wildcards supported, e.g. `example.com` or `*.example.com`).
+   * **Associated Domains**: Append more domains if any (wildcards supported, comma-separated).
+   * **DNS Account**: Select the DNS account just added from the dropdown (e.g. `cloudflare-main`).
+3. Click **「Save and Apply」**.
+
+### Step 4: Track Application Progress and Renewal Status
+
+- **Real-time progress**: After saving, the system delivers a certificate renewal/application task (`of_ssl_single_renew`) to the Asynq queue. You can view detailed step-by-step logs (adding TXT records, DNS record global propagation probing, ACME validation, certificate issuance, etc.) in the admin task or node log pages.
+- **Automatic renewal**: All certificates issued via ACME are automatically managed by the system. The background Scheduler scans certificate validity daily and automatically triggers renewal via async tasks 7 days before expiry — no manual maintenance needed.

+OpenFlare's release chain centers on "immutable config versions". After you modify rules in the admin panel, you must publish and activate a new version for online Agents to auto-sync and apply.
+
+---
+
+## Pre-Release Checks
+
+Before starting, make sure the following conditions are met:
+
+| Check | Required State |
+| --- | --- |
+| **Server** | control panel started normally and you can log in to the admin panel |
+| **Agent** | at least one Agent node online (confirmable in「Node Management」) |
+| **Origin** | your backend origin service is reachable from the Agent host |
+| **Domain/testing** | the domain's DNS resolves, or you're ready to test with local hosts / curl Host header on the client |
+
+---
+
+## Step 1: Create the First Website Config
+
+For a quick verification, deploy a basic HTTP reverse proxy site first:
+
+1. Log in to the control panel, go to **「Website Management」->「Domain List」** in the left navigation, click **「Add Zone」**.
+2. Fill in the domain config:
+   * **Domain**: enter the test domain (e.g. `first.example.com`).
+   * **Bind Certificate**: choose not to bind a certificate (for HTTP quick verification).
+   * Click save to complete domain registration.
+3. Go to **「Rule Management」**, click **「New Rule」**:
+   * **Rule Name**: enter a simple identifier (e.g. `first-app-route`).
+   * **Domain Match**: fill in your test domain (e.g. `first.example.com`).
+   * In the **「Reverse Proxy」** tab below, set the origin mode to「Direct Upstream」.
+   * **Upstream Address**: fill in the backend service address (e.g. the test-only `http://httpbin.org`).
+   * Click save to create the rule.
+
+> [!TIP]
+> **About HTTPS and certificate preparation**
+> This section only guides the quick deployment of a basic HTTP rule. To import an existing SSL certificate or auto-issue one from Let's Encrypt via ACME and enable HTTPS proxying on port 443, go to [Create a Reverse Proxy Config](./proxy-config.md) for detailed steps.
+
+---
+
+## Step 2: Preview and Publish a Config Version
+
+The new website config is still a draft in the Server database and needs a released version to be distributed to the data plane:
+
+1. Click the **「Preview and Publish」** button in the top-right of the control panel; the system shows the physical config file diff for the newly added route.
+2. After confirming the rendered config is correct, click **「Confirm Publish」**.
+3. The control plane generates a unique config version number (format `YYYYMMDD-NNN`).
+
+---
+
+## Step 3: Verify the Agent Applied It
+
+After publishing, the control plane immediately notifies online Agents via WebSocket (if the WebSocket is offline, the Agent detects it as a diff in its heartbeat):
+
+1. **Admin-side verification**: go to「Node Management」-> click the node to open details; check that the**current version number** has changed to the just-published latest active version and the「Apply Records」show success.
+2. **Edge node verification**: check application via logs on the Agent host:
+   ```bash
+   # If the Agent is Docker-deployed
+   docker logs openflare-agent
+   
+   # If the Agent is deployed with local systemd
+   journalctl -u openflare-agent -n 50 --no-pager
+   ```
+3. **Connectivity test**:
+   On the client machine, use `curl` with a test Host header against the Agent node's IP for final verification:
+   ```bash
+   curl -I -H "Host: first.example.com" http://AGENT_NODE_IP
+   ```
+   If the returned status code matches the backend origin's response, your first reverse proxy rule has successfully landed on the edge node!

+# Pages Static Hosting Usage
+
+You will learn: how to deploy pre-built static sites via local upload, Remote URL, or public GitHub Release assets; configure SPA Fallback and API reverse proxy; and safely check for updates, auto-publish, and roll back.
+
+---
+
+## Core Mechanics and Page Structure
+
+OpenFlare Pages is inspired by Cloudflare Pages' Direct Upload and deployment history interaction, but currently handles **pre-built artifacts** rather than building from repository source. The project detail is organized as "current production deployment → deployment source → deployment history": source configuration can change, while created deployments stay immutable.
+
+```text
+Local upload ─> unified validation / upload.Ingest ─> new candidate ─> admin explicit activation ─┐
+Remote URL ── Server restricted download ─────────────┐                                            │
+GitHub Release asset ─ Server resolves ───────────────┴─> create/load deployment ────────────────┤
+                                                       └─> source sync atomic activation ────────┘
+                                                                                                   |
+                                                                                                   v
+                                                                        Agent pulls per-project latest
+                                                                                                   |
+                                                                                                   v
+                                                                        OpenResty local static serving
+```
+
+External URLs, GitHub metadata, and auto-checks are handled only by the Server. The Agent only pulls the currently active deployment package from the control plane; it does not receive external source credentials, nor does it run `git clone`, dependency installation, or build commands.
+
+## Step 1: Create a Project
+
+1. Log in to the admin panel, go to **「Pages」**, click **「Create Project」**.
+2. Fill in the project name and a unique Slug.
+3. Configure the content entry:
+   * **Entry file name**: default `index.html`.
+   * **Static asset root path (RootDir)**: fill in the relative path when artifacts are in a subdirectory like `dist/`; leave empty when artifacts are at the archive root.
+4. Set SPA Fallback and API proxy as needed. RootDir and entry file are project-level configs applied uniformly to all sources.
+
+## Step 2: Choose a Deployment Source
+
+### 1. Manual Upload
+
+Without a persistent source configured, the project stays in manual mode. Click **「Upload Deployment Package」** to select a pre-built archive; a successful upload creates a candidate deployment, which you then explicitly activate from the deployment history. Re-uploading does not modify existing deployments.
+
+Supported formats: `zip`, `tar.gz` / `tgz`, `tar.xz` / `txz`, `tar.bz2` / `tbz2`, `tar`, and `7z`.
+
+### 2. Remote URL
+
+In the deployment source card select **Remote URL**, fill in the HTTP(S) address and choose a network policy:
+
+* **public**: default policy; rejects loopback, private network, link-local addresses, DNS rebinding, self-signed TLS, and redirects to non-public targets.
+* **trusted_internal**: only for explicitly trusted intranet or self-signed services; requires a second risk confirmation before saving.
+
+After saving, the address is only displayed masked. You don't need to re-enter it when editing other configs; only submit a new URL when choosing to change the address. Remote sources only offer **「Sync and Publish」**: the Server downloads, validates, and atomically activates each time — no "check for updates", scheduled checks, or auto-updates.
+
+### 3. GitHub Release
+
+GitHub sources only support public `github.com` repositories. Fill in:
+
+* A repository address in `https://github.com/{owner}/{repo}` format;
+* **Latest Release** or a **fixed Tag**;
+* An exact, case-sensitive Release Asset filename, default `dist.zip`.
+
+Both options support manual **「Check for Updates」** and **「Sync and Publish」**. Differences:
+
+* **latest**: supports a check interval of 5–1440 minutes, default 1440 minutes (24 hours); auto-update is off by default. When enabled, the scanner asynchronously syncs and publishes only when a new revision is found.
+* **tag**: only supports manual admin checks and sync; does not participate in the scheduled scanner.
+
+"Check for updates" only resolves the Release/asset and advances the version cursor without downloading the deployment package; "Sync and publish" downloads, validates, creates or reuses a deployment, and activates it. If the asset under the same Release is replaced, the source enters **「Needs Confirmation」** — you must confirm the exact revision shown before publishing, to avoid silent overwrites.
+
+GitHub Release sources only import pre-built artifacts; they do not build from repository source.
+
+### 4. Switch or Delete a Source
+
+You can switch between Manual, Remote, and GitHub Release. Modifying or deleting a source does not delete the current production deployment or historical deployments; switching back to manual mode lets you continue uploading and explicitly activating.
+
+## Deployment Package Security Limits
+
+Deployment packages must satisfy these constraints:
+
+* Archive size is controlled by the system config `pages_max_package_size_mb`, default 100 MiB, configurable 1–2048 MiB.
+* Expanded single-file and total size limits are "package size limit × 4", with a floor of 100 MiB; at most 1,000 regular files.
+* The control plane streams regular file bodies, checking declared size against actual bytes, and validates the project entry file.
+* Absolute paths, `..` path traversal, symlinks, hard links, and special files in archives are all rejected.
+
+The Agent also verifies SHA-256, real response byte limits, and post-extraction file count and total size on download; failures do not switch the existing `current`.
+
+## Step 3: Configure Advanced Routing Rules
+
+### 1. SPA Fallback
+
+When using front-end routing like React Router or Vue Router, enable **「SPA Fallback」** and set the entry path (usually `/index.html`). When a visitor accesses a physical path that doesn't exist, OpenResty falls back to the entry file for the front-end router to handle.
+
+### 2. API Reverse Proxy
+
+Pages can forward a specified prefix to a backend API under the same domain:
+
+* **APIProxyPath**: match prefix, e.g. `/api`.
+* **APIProxyPass**: backend address, e.g. `http://10.0.0.5:8080`.
+* **APIProxyRewrite**: optional path rewrite rule.
+
+Requests matching the API prefix go through the reverse proxy; other requests continue to be served by the static site.
+
+## Step 4: Bind a Route and First Publish
+
+1. Create or edit a proxy rule.
+2. Set the origin type to **Pages** and select the Pages **project**.
+3. Preview the config, then publish and activate.
+
+The route binds to a stable project ID, not a specific deployment. The first publish gives the Agent the project anchor; afterwards, local uploads, source syncs, auto-updates, or manual rollbacks only change the project's active deployment — the Agent converges via the latest hash reconciliation without needing to republish the main config.
+
+## Operations, Status, and Rollback
+
+* The source card shows the last check/sync time, found vs. applied revision, next check time, and security errors. While a check or sync task runs, the page polls the task status; when latest is idle, it refreshes at low frequency only near the check time.
+* A failed auto-update does not replace the old active deployment; a single source failure does not block the scanner from processing other projects.
+* Activating another deployment in the history is a manual rollback. The system fences in-flight source tasks and disables that source's auto-update to avoid the next latest round overwriting your manual choice; re-activating the current version is a no-op.
+* The Agent downloads to a temp file, verifies SHA-256, extracts safely, then atomically switches `current`. Any failure keeps the old content; with multi-project reconciliation, a single project failure does not affect others.
+
+> [!TIP]
+> For the source state machine, auto scanner, upload compensation, immutable deployments, and Agent atomic switching, see [Pages Static Hosting Design](../design/pages-design.md).

+# Create a Reverse Proxy Config
+
+You will learn: how to create and publish a reverse proxy website configuration from scratch, step by step, in OpenFlare. This guide walks you through certificate import and application, origin definition, route rule configuration, version release, and connectivity verification.
+
+---
+
+## Recommended Workflow
+
+In the gateway control plane, follow these steps to add a new reverse proxy rule:
+
+```text
+  [ Step 1. Certificate Management ] ──► [ Step 2. Origin Definition (optional) ] ──► [ Step 3. Add Website Config ]
+                                                                   │
+  [ Step 5. Verify Access ] ◄── [ Step 4. Publish & Activate Version ] ◄───────────────┘
+```
+
+---
+
+## Step 1: Prepare Certificates
+
+Before using HTTPS-secured traffic, you need to prepare the corresponding TLS certificate (supports manually importing an existing certificate, or automatically applying from a CA via DNS validation with managed renewal).
+
+To keep this guide concise, the certificate details (including creating a dedicated DNS API Token in Cloudflare) have been split into a dedicated guide. First go to **[TLS Certificates & Auto-Renewal](./certificates.md)** to prepare the certificate, then come back to continue.
+
+---
+
+## Step 2: Prepare the Upstream Origin (optional)
+
+An Origin represents the backend real service address being proxied. Although you can fill in an IP directly when creating a website, it is recommended to register origins in the origin library first for reuse and maintenance:
+
+1. Go to **「Website Management」->「Origin Addresses」** in the left navigation, click **「Add Origin」**.
+2. Fill in the origin name (e.g. `production-api`).
+3. Enter a valid upstream address (e.g. `http://10.0.0.10:8080`) and save.
+
+---
+
+## Step 3: Create the Website Config
+
+Once the certificate and origin are ready, create the core website proxy route:
+
+1. Go to **「Website Management」->「Domain List」**, click **「Add Zone」**:
+   * **Domain**: Enter the domain bound to this site.
+   * **Bind Certificate**: Select the certificate prepared or applied for in Step 1.
+2. Configure the request route rule: go to the **「Rule Management」** page, click **「New Rule」** or edit an existing rule:
+   * **Rule Name**: Enter a unique simple identifier (e.g. `app-portal-route`).
+   * **Domain Match**: Enter the corresponding domain (wildcards or exact domains supported; must match the registered domain above).
+   * In the **「Reverse Proxy」** tab below, select the origin mode as「Direct Upstream」.
+   * **Origin Selection**: Select the origin created in Step 2 from the dropdown; or choose manual input and fill in `http://10.0.0.20:9000`.
+3. Click save to create the config.
+
+---
+
+## Step 4: Publish and Apply the Config
+
+Website configs added in the admin panel are only saved in the Server database — **they do not take effect immediately**. You must generate a config version snapshot and distribute it to the Agent edge nodes:
+
+1. Click the **「Preview and Publish」** button in the top-right corner of the control panel.
+2. Review the config file diff, confirming the newly added `server` block and certificate binding rules are correct.
+3. Click **「Confirm Publish」**.
+4. **Agent application mechanism**:
+   * The Agent node on the data plane detects the active version Checksum change in its heartbeat, and automatically pulls the full OpenResty config files and certificate bundle locally.
+   * It automatically runs a local config validation (similar to `openresty -t`); after confirming no syntax errors, it performs a smooth reload.
+   * If reload or validation fails, the Agent safely blocks and rolls back to the previous stable version to keep the node highly available.
+
+---
+
+## Step 5: Connectivity and Rollback Verification
+
+### 1. Verify Access
+You can verify the new config takes effect as follows:
+* **Browser access**: Open `https://your-domain.com` directly in a browser and check whether it proxies the backend successfully.
+* **CLI verification** (recommended): probe with `curl`:
+  ```bash
+  curl -I https://your-domain.com
+  ```
+* **Bypass DNS validation**: if your domain is not yet resolvable, temporarily send a `Host` header request to the Agent node's physical IP:
+  ```bash
+  curl -I -H "Host: your-domain.com" https://AGENT_NODE_IP --insecure
+  ```
+
+### 2. One-Click Second-Level Rollback
+If the released config causes an online business issue:
+1. Navigate to the **「Version Release」** menu on the left.
+2. Find the previous stable version before the release in the history list.
+3. Click **「Activate」**.
+4. All online Agent nodes will automatically reload the historical config within seconds for second-level risk avoidance.
+
+---
+
+## Edge Cache (optional)
+
+The **「Cache」** page in the site details can enable edge `proxy_cache` (requires **Performance Settings → Global OpenResty Cache** to be enabled at the same time). Behavior mirrors the Cloudflare default model; see [Edge Cache Strategy Design](../design/edge-cache-design.md).
+
+### Recommended Settings
+
+| Item | Suggestion |
+| --- | --- |
+| Strategy | **Standard static assets** (recommended default): only css/js/map/images/fonts, **not HTML/JSON** |
+| Login Cookie | Is **not** separately skipped from caching; users with sessions can still hit static assets |
+| Origin | Static assets: `Cache-Control: public, max-age=…`; dynamic/personalized must be `private` or `no-store` |
+| Response Set-Cookie | Is not written to the edge cache |
+| No origin cache headers | Uses default Edge TTL by status code (e.g. ~120 min for 200) |
+
+### Advanced Strategy「All Cacheable GET」
+
+Similar to Cloudflare Cache Everything: the path is no longer limited by extension. If the origin does not declare `private`/`no-store` for HTML, **personalized pages may be cached and served across users**. Use only when origin cache headers are correct or content is globally consistent.
+
+### How It Takes Effect
+
+The cache switch and strategy are written into the config snapshot. After saving the site, you must **publish and activate the config version** for the Agent to apply it. Changing the UI only without publishing leaves nodes on the old rules.
+
+### Quick Self-Check
+
+1. Global cache on, site cache on, strategy「Standard static assets」.  
+2. Publish the config and confirm nodes applied successfully.  
+3. Request the same `/assets/app.js` (or a hashed immutable path) twice with a login cookie; the `cache_status` in access logs should be **HIT** on the second request.  
+4. If still「not cached」: check whether the strategy matches the path extension, whether it is a non-GET request, whether the origin returns `Set-Cookie` / `private`, and whether the node applied the new version.

+# Quick Start
+
+You will learn: how to start the OpenFlare Server with Docker Compose, complete the first login, connect your first Agent, and verify that a config has been published to a node.
+
+OpenFlare's minimal runtime consists of:
+
+| Component | Responsibility |
+| --- | --- |
+| Server | admin UI, admin API, Agent API, config rendering, version release, and state storage |
+| Agent | runs on proxy nodes; pulls config, writes OpenResty, executes validation and reload |
+| OpenResty | actually receives traffic and reverse proxies to origins |
+
+The Agent uniformly controls the runtime via the OpenResty binary. Local deployment requires an `openresty` executable on the node; Docker deployment can directly run the Agent image with a built-in OpenResty.
+
+## Environment Requirements
+
+| Item | Requirement |
+| --- | --- |
+| Docker / Docker Compose | starts the Server and its PostgreSQL, Valkey dependencies; also runs the Agent if using the Docker Agent |
+| OpenResty | local Agent installs need an executable `openresty`, or specify the path in the install script |
+| Reachable port | Server listens on `3000` by default; Agent nodes must be able to reach the Server address |
+
+---
+
+## 1. Start the Server
+
+Quick start recommends the standard **PostgreSQL + Valkey** deployment.
+
+Create a `docker-compose.yaml` in an empty directory:
+
+```yaml

+docker compose up -d
+```
+
+Confirm the containers are running:
+
+```bash
+docker compose ps
+docker compose logs -f openflare
+```
+
+After seeing `server listening` and the `openflare-server` container status running, open in a browser:
+
+```text
+http://localhost:3000
+```
+
+Default account:
+
+| Username | Password |
+| --- | --- |
+| `admin` | `12345678` |
+
+> [!WARNING]
+> For your system's security, change the default password immediately after the first login.
+
+If you forget the password and no password-recovery channel is configured, reset it with:
+
+```bash
+go run main.go reset-passwd --user admin
+```
+
+Without `--password`, the command auto-generates a random password and prints it to the terminal; you can also explicitly specify a new password with `--password`.
+
+---
+
+## 2. Prepare an Agent Token
+
+Agents can connect with two credential types:
+
+| Credential | Use Case |
+| --- | --- |
+| `discovery_token` | first-time auto registration; the Server exchanges it for a node-specific Token |
+| `agent_token` | node already created or assigned in the admin panel; use the node-specific Token directly |
+
+Prepare one of these credentials in the admin panel, then continue.
+
+- **`discovery_token`** menu path:「System Settings」->「OpenFlare」tab ->「Discovery Token & Deployment」→ Discovery Token
+- **`agent_token`** menu path: after creating a node in「Node Management」, click into the node detail page to see its dedicated Token.
+
+---
+
+## 3. Install / Run the Agent
+
+Docker image deployment is recommended; you can also deploy to the local host via the install script.
+
+### Option A: Run the Agent with Docker (recommended)
+
+Run the Agent image directly on the proxy node:
+
+```bash
+docker pull ghcr.io/rain-kl/openflare-agent:latest
+docker rm -f openflare-agent 2>/dev/null || true
+docker run -d --name openflare-agent --restart unless-stopped \
+  -p 80:80 -p 443:443/tcp -p 443:443/udp \
+  -v openflare-agent-pages:/data/var/lib/openflare/pages \
+  -e OPENFLARE_SERVER_URL=http://your-server:3000 \
+  -e OPENFLARE_AGENT_TOKEN=YOUR_AGENT_TOKEN \
+  ghcr.io/rain-kl/openflare-agent:latest
+```
+
+### Option B: Run the install script (local deployment)
+
+Run the install script on the proxy node.
+
+With `discovery_token`:
+
+```bash
+curl -fsSL https://raw.githubusercontent.com/Rain-kl/OpenFlare/main/scripts/install-agent.sh | bash -s -- \
+  --server-url http://your-server:3000 \
+  --discovery-token YOUR_DISCOVERY_TOKEN
+```
+
+With the node-specific `agent_token`:
+
+```bash
+curl -fsSL https://raw.githubusercontent.com/Rain-kl/OpenFlare/main/scripts/install-agent.sh | bash -s -- \
+  --server-url http://your-server:3000 \
+  --agent-token YOUR_AGENT_TOKEN
+```
+
+The script defaults:
+
+| Item | Default |
+| --- | --- |
+| Install directory | `/opt/openflare-agent` |
+| Config file | `/opt/openflare-agent/agent.json` |
+| systemd service | `openflare-agent.service` |
+| OpenResty path | auto-finds `openresty` when unspecified |
+
+Confirm the Agent service state:
+
+```bash
+systemctl status openflare-agent
+journalctl -u openflare-agent -f
+```
+
+Without systemd, the script prints a manual start command.
+
+---
+
+## 4. Next Steps
+
+After starting the control panel and connecting an Agent node, you've successfully built the base runtime environment of the OpenFlare gateway. Continue with these two guides to deploy your first reverse proxy site:
+
+1. **Publish your first website**:
+   * See [Publish First Configuration](./first-site.md). It guides you to publish your first proxy rule in the simplest way (plain HTTP) and verify the node applied it.
+2. **Full reverse proxy config (HTTPS & origin management)**:
+   * See [Create a Reverse Proxy Config](./proxy-config.md). It guides you from certificate import/application to domain HTTPS certificate binding, origin management, and preview release.
+
+---
+
+## When You Hit Problems
+
+Handle in this order:
+
+1. Upgrade Server and Agent to the latest version; confirm whether the problem persists.
+2. Re-publish and activate a config version, wait for the node to apply.
+3. Run「Force Sync」on the target node in the node detail page to push an immediate config pull.
+4. Rebuild or reinstall the Agent (re-run the install script).
+5. If none of the above works, file a [GitHub Issue](https://github.com/Rain-kl/OpenFlare/issues) with the Server logs and node apply records.
+
+More troubleshooting: [Troubleshooting](./troubleshooting.md).

+# SSO Login Configuration
+
+You will learn: how to configure an OIDC third-party login entry for OpenFlare, fill in the callback URL, and how third-party accounts bind to local users.
+
+OpenFlare connects third-party login through OIDC auth sources. Any service providing standard OIDC Discovery (Google, Keycloak, authentik, Logto, Casdoor, etc.) can be integrated.
+
+After an auth source is configured and enabled, it appears in the third-party account login area on the login page. Users can log in with a third-party account, or bind a third-party account to the current local account while logged in.
+
+## Prerequisites
+
+| Item | Description |
+| --- | --- |
+| Server access URL | configured in admin「System Settings」->「System Settings」tab ->「General Settings」; must match the address users' browsers actually visit (protocol, domain, port) |
+| Auth source name | unique identifier inside OpenFlare, e.g. `company-oidc` |
+| Client ID | provided after creating the app on the third-party platform |
+| Client Secret | provided after creating the app on the third-party platform |
+| OIDC Discovery URL | e.g. `https://idp.example.com/.well-known/openid-configuration` |
+
+The auth source name may only contain letters, digits, hyphens, or underscores, and must start with a letter or digit.
+
+## Callback URL
+
+The Redirect URI / Callback URL on the third-party platform is fixed to:
+
+```text
+<server access URL>/login
+```
+
+For example, with a server access URL of `https://openflare.example.com`:
+
+```text
+https://openflare.example.com/login
+```
+
+The callback URL only relates to the「server access URL」and does not include the auth source name. After the third-party platform completes authorization, it redirects here, and the OpenFlare login page uses the authorization code to complete login or binding.
+
+## Configure OIDC Login
+
+1. Create an app or client on the OIDC Provider; choose Web / Confidential Client as the app type.
+2. Set the Redirect URI / Callback URL to `<server access URL>/login`.
+3. Copy the Client ID and Client Secret.
+4. Get the Provider's Discovery URL, usually ending in `/.well-known/openid-configuration`.
+5. Log in to the OpenFlare admin panel, go to **「System Settings」**, select the **「Security Settings」** tab, and add an auth source in the **「Auth Source Management」** section.
+6. Choose type `OIDC`; fill in the auth source name, display name, Client ID, Client Secret, and OIDC Discovery URL.
+7. Scope defaults to `openid profile email`. If the Provider restricts scopes, adjust according to the Provider's allowed values.
+8. Save and enable the auth source.
+
+Once enabled, the login page shows the corresponding third-party login button.
+
+## Login and Binding Behavior
+
+When a third-party account returns to OpenFlare, it is handled as follows:
+
+| Scenario | Behavior |
+| --- | --- |
+| Third-party account already bound to a local user | log in directly |
+| User already logged in and initiates third-party authorization | bind to the current local user |
+| Third-party account not bound, and registration allowed | auto-create a normal user and bind |
+| Third-party account not bound, and registration disabled | require entering an existing local account password to bind |
+
+To allow only existing users to use SSO, turn off user registration. Unbound third-party accounts then enter the bind-existing-account flow.
+
+## Modifying an Auth Source
+
+When editing an auth source, leaving the Client Secret input empty keeps the existing secret; entering a new value overwrites and saves it.
+
+Changing the auth source name does not affect the callback URL, so the third-party platform config doesn't need to change.
+
+## FAQ
+
+### Returns `invalid_scope`
+
+The third-party platform doesn't allow the currently configured scope. The OIDC default scope is `openid profile email`. Adjust the scope on the auth source edit page, or allow the scope on the third-party platform.
+
+### Callback URL mismatch
+
+Check that the Redirect URI / Callback URL on the third-party platform exactly matches `<server access URL>/login`. Protocol, domain, port, and path must all match.
+
+### Login page doesn't show the third-party login button
+
+Check that the auth source is enabled and that the Client ID and Client Secret are saved. OpenFlare validates these fields before enabling the auth source.
+
+### Client Secret saved, but the list doesn't show the plaintext
+
+This is expected. OpenFlare never echoes the Client Secret through the API; it only shows whether a secret is configured.

+# Troubleshooting
+
+You will learn: how to troubleshoot OpenFlare Server, database, login, Agent, OpenResty, and config release issues by symptom.
+
+First determine which layer the problem is in: browser, Server, database, Agent, OpenResty, origin, or DNS. OpenFlare configs are not written to all nodes online directly — only after the active version changes do Agents detect and apply it in their heartbeat.
+
+## Quick Locate
+
+| Symptom | Look Here First |
+| --- | --- |
+| Admin panel won't open | Server container/process logs, port listening |
+| Login abnormal | default account, Session Cookie, Server logs |
+| Data won't save | DB connection, SQLite file permissions, PostgreSQL health |
+| Agent offline | Agent logs, Token, Server address, network connectivity |
+| Node not updated after release | active version, node heartbeat, apply records |
+| OpenResty apply failure | apply records, Agent logs, certificates, upstream addresses, port usage |
+| Access analytics empty | OpenResty container state, observability port, Agent backfill logs |
+| Static assets never hit cache | global/site cache switch, policy extensions, whether config released, access log `cache_status`, origin Set-Cookie / Cache-Control |
+
+## Server Won't Start
+
+1. Check the logs:
+
+```bash
+docker compose logs -n 200 openflare
+```
+
+For source runs, check terminal output.
+
+2. Check port usage:
+
+```bash
+lsof -i :3000
+```
+
+3. If using PostgreSQL, confirm DB health:
+
+```bash
+docker compose ps postgres
+docker compose logs -n 100 postgres
+```
+
+4. If using SQLite, confirm the DB file directory is writable:
+
+```bash
+ls -ld "$(dirname /path/to/openflare.db)"
+```
+
+Common causes:
+
+| Log or Symptom | Handling |
+| --- | --- |
+| DB connection failed | check `DB_HOST`, `DB_PORT`, `DB_USERNAME`, `DB_PASSWORD`, `DB_NAME`, `DB_SSL_MODE` consistency |
+| SQLite can't create file | check the `SQLITE_PATH` directory exists and is writable |
+| Port occupied | change `PORT` or `--port`, or stop the process holding the port |
+
+## Admin Panel Won't Open or Is Blank
+
+1. Confirm the Server is listening:
+
+```bash
+curl -I http://127.0.0.1:3000
+```
+
+2. Check that the browser access address matches the reverse proxy config.
+
+## Default Account Can't Log In
+
+The default account is `admin` / `12345678`. If the password was changed after first login, use the changed one.
+
+Steps:
+
+1. Confirm you're connected to the intended database — avoid `SQLITE_PATH` or `DB_HOST` / `DB_NAME` pointing at another environment.
+2. Check whether the Server log uses `sqlite` or `postgres`.
+3. In browser dev tools, confirm admin API requests carry the Session Cookie correctly.
+4. Clear browser cache and cookies, then log in again.
+
+### Emergency Admin Password Reset
+
+If you forget the `admin` password, reset it with the `reset-passwd` command (supports SQLite and PostgreSQL):
+
+```bash
+go run main.go reset-passwd --user admin --password your-new-password
+```
+
+With SQLite, stop the Server process first to avoid DB file lock conflicts. Without `--password`, the command generates a random password and prints it. After resetting, log in and change the password immediately.
+
+## Agent Can't Register or Stays Offline
+
+On the Agent node:
+
+```bash
+curl -I http://your-server:3000
+```
+
+Check Agent logs:
+
+```bash
+journalctl -u openflare-agent -n 200 --no-pager
+```
+
+Check the config file:
+
+```bash
+sed -n '1,160p' /opt/openflare-agent/agent.json
+```
+
+Confirm:
+
+| Config | Description |
+| --- | --- |
+| `server_url` | must be a Server address reachable by the Agent node |
+| `agent_token` / `discovery_token` | at least one filled in |
+| `heartbeat_interval` | supports millisecond integer or Go duration string |
+| `request_timeout` | increase for slow networks |
+
+If logs say the Token is invalid, prepare a new Token in the admin panel, update `agent.json`, then restart:
+
+```bash
+systemctl restart openflare-agent
+```
+
+## Node Didn't Apply the New Version After Release
+
+Check in order:
+
+1. Is the target version activated in the version page?
+2. Is the node online, and did the last heartbeat time update?
+3. Do the apply records show success, warning, or failure for the target version?
+4. Is the website config enabled? Disabled sites don't participate in release rendering.
+5. Do Agent logs show pull, validation, reload, or rollback messages?
+
+View Agent logs:
+
+```bash
+journalctl -u openflare-agent -f
+```
+
+Note: once a target `version + checksum` fails to apply and rolls back, the Agent blocks retrying that target in local state. After fixing the config, republish to generate a new checksum, or activate an older version to roll back.
+
+If this is the Agent's first config apply with no historical `nginx.conf` to roll back to, the failed target is still blocked, but the Agent enters a safe fallback runtime. The apply records and Agent logs will contain `fallback runtime started`; OpenResty only listens on port `80` and returns `503` with `OpenFlare: No Valid Configuration` for everything, while keeping the local `stub_status` health endpoint. After fixing the config and republishing a new version, the Agent overwrites the fallback config and resumes normal proxying.
+
+## OpenResty Apply Failure
+
+Common causes:
+
+| Cause | Troubleshooting |
+| --- | --- |
+| Domain or server block conflict | check whether the same domain is used by multiple site configs |
+| Invalid upstream address | confirm all upstreams are `http://` or `https://` |
+| Multi-upstream format violates constraints | multi-upstream must be plain `scheme://host[:port]` |
+| Certificate missing or wrong path | check whether the domain is bound to a cert and the Agent cert dir is writable |
+| Port occupied | check local `80`, `443` ports |
+
+OpenResty config validation:
+
+```bash
+openresty -t -c /path/to/openflare/data/etc/nginx/nginx.conf
+```
+
+OpenResty running state:
+
+```bash
+ps aux | grep openresty
+```
+
+The Agent's periodic health check probes the local `http://127.0.0.1:<openresty_observability_port>/openflare/stub_status` to judge OpenResty liveness — it does not repeatedly run `openresty -t`. If a node is marked unhealthy, first confirm that local observability port is listening; if `host not found in upstream` appears only during config apply, the failure comes from config validation or reload, not the periodic health probe.
+
+Actual binary and main config paths follow `openresty_path` and `main_config_path` in `agent.json`.
+
+## HTTPS Not Taking Effect
+
+1. Confirm the certificate is uploaded or managed.
+2. Confirm the site config's domain is bound to a certificate.
+3. Confirm a new version was published and activated.
+4. Check whether the apply records succeeded.
+5. Inspect the certificate and status code with `curl`:
+
+```bash
+curl -Iv https://your-domain
+```
+
+Domains without a bound certificate are not auto-added to the HTTPS config — that's expected.
+
+## Access Analytics Empty
+
+1. Confirm the node successfully applied config including the observability Lua assets.
+2. Confirm OpenResty is running.
+3. Check Agent logs for observability collection or backfill failures.
+4. Check whether `openresty_observability_port` is occupied (default `18081`).
+5. Confirm the Server's DB cleanup policy hasn't deleted the relevant time window.
+
+## Edge Cache Hit-Rate Anomalies
+
+Access log cache three states: **hit** (HIT/STALE/REVALIDATED/UPDATING), **origin** (MISS/EXPIRED), **not cached** (BYPASS or empty — request didn't enter a cacheable path or response wasn't stored). Design: [Edge Cache Strategy Design](../design/edge-cache-design.md).
+
+### Checklist
+
+1. Global OpenResty cache enabled in **Performance Settings**.  
+2. Site **Cache** enabled and policy matches the path (「Standard static assets」covers only built-in extensions, **not HTML/JSON**; `.js.map`'s extension is `map`, in the default table).  
+3. Config version **published and activated**, node apply records succeeded (changing cache rules without publishing leaves nodes on old bypass logic).  
+4. Request method is **GET** (non-GET is never cached).  
+5. Origin doesn't return **`Set-Cookie`** for the target URL (if so, not written to the edge).  
+6. Origin doesn't declare **`Cache-Control: private` / `no-store`** (shared caches won't store).  
+7. Browser DevTools "Disable cache" only affects the browser; whether the edge HITs is judged by access log `cache_status`, not the Network panel.
+
+### Common Misconceptions
+
+| Symptom | Explanation |
+| --- | --- |
+| Everything「not cached」after login, never republished | old config bypassed session cookies; after upgrade you must republish node configs |
+| `/api/foo` or `/index.html` not cached under `static` | expected (extension not in the default cacheable table) |
+| HTML cross-user leakage after switching to `all` | origin didn't forbid shared caching; switch back to `static` or add `private`/`no-store` to dynamic responses |
+| URLs with `?v=` have low hit rates | default cache key includes the full `$request_uri`; different query = different object |
+| First MISS, second still MISS | check whether the origin sets `Set-Cookie`/`private` every time, or node disk/cache `inactive` is too short |
+
+### Expected Behavior (aligned with Cloudflare defaults)
+
+* A logged-in user accessing `/_app/**/*.js` static assets: **can HIT**.  
+* Response with `Set-Cookie` or `private`: **not stored**.  
+* Cacheable status codes without origin cache headers: use the default Edge TTL (e.g. ~120 min for 200).

+# Tunnel & Intranet Penetration
+
+You will learn: the design principles of OpenFlare's intranet penetration tunnels, core concepts (relay nodes and tunnel clients), and how to publish an intranet dev environment or private cloud service to a public domain step by step, securely and stably.
+
+In many real development and ops scenarios, origin services run inside a LAN, on a local dev machine, or in a private VPC — with no public IP and no way to configure port mapping on the border firewall or router.
+
+OpenFlare provides a complete **reverse-relay tunnel penetration** solution. You only initiate an outbound secure connection from the intranet to a public relay node — no inbound ports need to be configured — and public web traffic is routed into the intranet origin, while enjoying the gateway's automatic TLS certificate management and WAF protection.
+
+---
+
+## Core Concepts
+
+Before using intranet penetration, get familiar with these components:
+
+| Component | Description | Corresponding Entity |
+| --- | --- | --- |
+| **Relay node** | a traffic relay service deployed at the public edge; listens for the intranet client's long connections and bridges gateway Agent (OpenResty) and intranet traffic | `tunnel_relay` node guarded by `openflare-relay` |
+| **Tunnel** | a logical penetration client instance with a globally unique ID and an auth token, identifying one concrete intranet environment | `tunnel_client` node created in「Node Management」, assigned a dedicated Tunnel Token |
+| **Tunnel client** | a lightweight controller running in the intranet; auto-manages the underlying frpc tunnel child processes based on Server-dispatched config | `openflared` container or standalone binary deployed in the intranet |
+| **Tunnel upstream** | a special reverse proxy type in route rules. With this type, the gateway forwards public traffic to the local relay's Vhost port, eventually reaching the intranet origin | reverse proxy type configured in the「Rule Management」detail page, origin mode「Intranet Tunnel」with a bound Tunnel node |
+
+---
+
+## Recommended Order
+
+To publish an intranet service to the public, follow this order:
+
+1. Register and deploy at least one public **Relay node** and keep it online.
+2. Go to **「Node Management」**, create a node of type **Tunnel node (tunnel_client)**, and get the dedicated Token.
+3. Deploy and start the **tunnel client (OpenFlared)** on the intranet server.
+4. Confirm the Tunnel node's status shows「Online」in the admin panel.
+5. Add or edit a rule in **「Rule Management」**; in the「Reverse Proxy」tab choose origin mode **「Intranet Tunnel」**, bind the Tunnel node, and enter the intranet service port (e.g. `127.0.0.1:8080`).
+6. Publish and activate the new version.
+7. Access via the public domain to verify the tunnel link.
+
+---
+
+## Detailed Steps
+
+### Step 1: Prepare a Relay Node
+
+Intranet traffic needs a public relay node to transit. Before starting, make sure you have a usable relay server on the public network.
+
+1. Log in to the admin panel, go to **「Node Management」**.
+2. Add a new node and set **Node Type** to **Relay node (tunnel_relay)**.
+3. After saving, copy the node's dedicated `agent_token`.
+4. Start `openflare-relay` on your public server. Docker quick run:
+
+   ```bash
+   docker run -d --name openflare-relay --restart unless-stopped \
+     -p 7000:7000 \
+     -e OPENFLARE_SERVER_URL=http://<your-Server-public-IP>:3000 \
+     -e OPENFLARE_AGENT_TOKEN=<the-AgentToken-you-copied> \
+     -v openflare-relay-data:/var/lib/openflare-relay \
+     ghcr.io/rain-kl/openflare-relay:latest
+   ```
+
+   > [!IMPORTANT]
+   > Open port `7000` (the frpc client connection control port, default `relay_bind_port`) in the cloud server's security group. If your Server and relay node are on the same machine, `OPENFLARE_SERVER_URL` here should point to the Server's public or intranet communication IP.
+
+### Step 2: Create a Tunnel Node in the Admin Panel
+
+1. Navigate to **「Node Management」** in the admin sidebar.
+2. Click **「Add Node」**; in the dialog choose node type **「Tunnel node (tunnel_client)」**.
+3. Fill in the node name and description, click save.
+4. Click into the Tunnel node's detail page; find the dedicated **Tunnel Token** and the one-click client deployment command.
+
+### Step 3: Deploy the Intranet Client (OpenFlared)
+
+Back on your intranet server, run the client with the copied deployment command.
+
+#### Option A: Deploy with Docker (recommended)
+
+The official `openflared` image bundles the supervisor daemon and the `frpc` runtime — out of the box, no extra dependencies:
+
+```bash
+docker run -d --name openflared --restart unless-stopped \
+  -e OPENFLARE_SERVER_URL=http://<your-Server-public-IP>:3000 \
+  -e OPENFLARE_TUNNEL_TOKEN=<the-TunnelToken-you-copied> \
+  -v openflared-data:/app/data \
+  ghcr.io/rain-kl/openflared:latest
+```
+
+#### Option B: Run the host binary manually
+
+If Docker isn't convenient, download or build the `flared` binary yourself:
+
+1. Create a `flared.json` config file next to the program on the intranet machine:
+   ```json
+   {
+     "server_url": "http://<your-Server-public-IP>:3000",
+     "tunnel_token": "<the-TunnelToken-you-copied>",
+     "frpc_path": "/usr/local/bin/frpc",
+     "data_dir": "./data"
+   }
+   ```
+2. Start it:
+   ```bash
+   ./flared -config ./flared.json
+   ```
+
+#### Status Confirmation
+
+After starting, the intranet client sends heartbeat syncs to the control plane over outbound connections:
+1. Refresh the **「Node Management」** list; the Tunnel node's status light should turn green **「Online」**.
+2. Click into the node detail page to see which public Relay nodes the intranet client is connected to.
+
+### Step 4: Configure the Route and Bind the Tunnel Upstream
+
+Now configure public reverse proxying and domain access for your intranet service:
+
+1. First go to **「Website Management」->「Domain List」** and register the domain you want to expose.
+2. Go to **「Rule Management」**, click **「New Rule」** or edit an existing rule.
+3. In the **「Reverse Proxy」** tab, switch the **origin mode** to **「Intranet Tunnel」**.
+4. Select the online **Tunnel node** from the dropdown.
+5. Fill in the **intranet target address** (a local address/port reachable by the intranet client, e.g. `127.0.0.1:8080`) and **intranet protocol** (usually `http`).
+6. Configure other regular site options and save.
+
+### Step 5: Publish and Apply
+
+To let the gateway's OpenResty match and route domain traffic, publish a new config version:
+
+1. Click **「Preview and Publish」** in the top-right nav; confirm the generated site config is correct.
+2. In the dialog, click **「Confirm Publish」**.
+3. The public-edge Agent now pulls the latest route: it forwards requests to the same-host `openflare-relay (frps)` vhost port.
+4. The intranet client `openflared (frpc)` receives the relayed packets and safely forwards them to the intranet `127.0.0.1:8080` service, returning the response along the same path.
+5. Visit the domain in a public browser to confirm the intranet service displays.
+

+### 1. One Tunnel, Multiple Services (multi-port mapping)
+
+You don't need a separate `openflared` container for every intranet service.
+
+To map multiple services in one intranet environment (e.g. `127.0.0.1:80` blog, `127.0.0.1:8080` API, `192.168.1.120:9000` intranet drive):
+1. Keep this one `openflared` client online.
+2. Create three separate website configs in the admin panel (each bound to its own public domain).
+3. Select **the same tunnel** as the origin mode for all three.
+4. Fill in the corresponding different ports or LAN IPs in each intranet target address (e.g. `127.0.0.1:80`, `127.0.0.1:8080`, `192.168.1.120:9000`).
+5. Publish and activate — one tunnel, many uses.
+
+### 2. Gateway Security Features Stack Seamlessly
+
+Because all public traffic first enters the public Agent node — HTTPS/TLS handshake and WAF engine interception happen there — then travels through the secure tunnel to the intranet:
+
+Your intranet service needs **zero modification** to enjoy:
+* **One-click HTTPS**: select or apply an SSL certificate for the domain directly in the admin panel; data is encrypted end-to-end.
+* **Global/custom WAF protection**: enable SQL injection blocking, XSS injection defense, and malicious geo-IP blocking.
+* **Human challenge (CC PoW)**: one-click defense against malicious CC requests to intranet APIs.
+
+---
+
+## Troubleshooting
+
+### 1. Tunnel shows「Offline」in the admin panel
+
+* **Check the Token**: verify the `tunnel_token` in `flared` logs or env vars matches the one generated in the admin panel.
+* **Check network connectivity**: the intranet server must be able to reach the Server address over outbound connections.
+* **Relay firewall not open**: check that the relay node's public `7000` port (or custom `relay_bind_port`) is opened to the public in the security group.
+
+### 2. Public domain returns 502 Bad Gateway / 504 Gateway Timeout
+
+* **Intranet service not running**: confirm the service at the intranet target address is started and listening on the intranet server.
+* **Target address unreachable**: if the intranet address is `127.0.0.1:8080`, ensure the service runs on the same host as `openflared`; if it's a LAN IP `192.168.x.x`, test LAN reachability from inside the `openflared` container.
+* **Check node state and logs**: view the Tunnel node detail and「Apply Records」in the admin panel; frpc process errors are logged in detail in the `flared` logs on the intranet host.
+
+### 3. Multi-relay network flapping or retry failures
+
+* When the control plane is associated with multiple Relay nodes, `openflared` spawns a separate frpc supervisor per Relay and periodically pulls topology state from the control plane within the `sync_interval` configured in `flared.json` (default 30s).
+* If a relay node frequently drops due to network jitter, the system auto-triggers exponential backoff retries (initial 1s, cap 60s). You may see `frpc process missing, starting` in the host logs — that's normal process self-healing; it reconnects automatically after the network recovers.

+# Uptime Kuma Monitoring Sync
+
+You will learn: how to enable and configure the Uptime Kuma auto-sync integration, control the sync scope and heartbeat probe parameters for monitored sites, and the underlying principles of differential synchronization between OpenFlare and Uptime Kuma.
+
+---
+
+## Feature Overview
+
+In edge multi-node operations, knowing the availability of each proxied site in time is critical. To avoid manually re-entering site information into a monitoring system, OpenFlare provides deep integration with the open-source monitoring service **Uptime Kuma**.
+
+Once enabled, OpenFlare starts a background sync scheduler that automatically syncs the proxy sites configured in the admin panel as HTTP monitor tasks in Uptime Kuma. It supports scope filtering, differential attribute updates, and automatic cleanup of decommissioned sites.
+
+---
+
+## Step 1: Configure the Integration in System Settings
+
+1. Log in to the admin panel, go to **「System Settings」** in the left navigation, select the **「OpenFlare」** tab, and configure the **「Uptime Kuma Integration」** section.
+2. Configure the following core connection parameters:
+   * **Enabled**: Turn on the integration switch.
+   * **Instance URL**: Your Uptime Kuma service address, e.g. `http://192.168.1.100:3001` or `https://kuma.example.com` (the protocol prefix `http://` or `https://` is required).
+   * **Username** and **Password**: Credentials for a Uptime Kuma account with admin privileges, used for API authentication.
+
+---
+
+## Step 2: Control Monitor Scope and Heartbeat Parameters
+
+In the integration panel you can finely control the monitor scope and probe behavior:
+
+### 1. Monitor Scope
+* **All sites**: Default option. OpenFlare automatically syncs all **enabled** proxy route sites. When a new site is created and enabled, or an old site is disabled, the monitor list is updated automatically.
+* **Selected sites**: Only monitor specified sites. After selecting this mode, click the **「Select Monitored Sites」** dialog. Inside the dialog you can filter sites by search and check the ones you want. Sites that are unchecked or not checked will not be synced (and will be automatically cleaned up if they already exist).
+
+### 2. Probe Frequency and Heartbeat Settings
+You can specify uniform probe parameters for auto-generated monitors:
+* **Sync Interval**: Frequency (minutes) of automatic differential sync, default `5` minutes. The control plane compares state with Uptime Kuma every 5 minutes.
+* **Heartbeat Interval**: Frequency (seconds) at which Uptime Kuma probes sites, default `60` seconds.
+* **Retry**: Maximum number of retries before a failed probe is judged Down, default `0`.
+* **Retry Interval**: Seconds to wait between retries, default `60` seconds.
+* **Request Timeout**: Seconds after which a probe request is judged timed out, default `48` seconds.
+
+---
+
+## Sync and Cleanup Mechanism
+
+* **Dedicated tag isolation**: All auto-created monitors are bound with the `OpenFlare`-specific tag (purple-blue). The sync and cleanup routines only operate on monitors with this tag, and will not interfere with or damage other monitors you created manually in Uptime Kuma.
+* **Differential incremental sync**: The sync routine periodically compares monitor metadata. When a domain or heartbeat configuration change is detected, only a differential update is performed to avoid interrupting historical statistics; when a site is disabled or moved out of scope, it is automatically taken offline and cleaned up.
+
+> [!TIP]
+> For details on the Socket.IO control flow, anti-pollution tag model, and differential comparison algorithm of Uptime Kuma monitoring sync, see [Uptime Kuma Sync Design](../design/kuma-design.md).

+# WAF Auto IP Group Rule Syntax
+
+Auto IP groups aggregate metrics per client IP from request logs, then use Expr expressions to decide whether to add an IP to the group list. Auto IP groups can be referenced by a WAF rule group's IP blocklist or allowlist; on config release, the Server only writes the IP group reference IDs into `waf_config.json` — IP group members are synced independently by the Agent to the local runtime file.
+
+## Config Structure
+
+An auto IP group config is a JSON object:
+
+```json
+{
+  "lookback": "1h",
+  "rules": [
+    {
+      "name": "Single-IP high-frequency 404 scanning",
+      "expr": "request_count > 100 && StatusRatio(404) >= 0.8"
+    }
+  ]
+}
+```
+
+Field reference:
+
+| Field | Type | Purpose |
+| --- | --- | --- |
+| `lookback` | string | lookback window duration in Go Duration syntax, e.g. `30m`, `1h`, `90m`. Defaults to `1h`, max 30 days. Compatible with the legacy `lookback_minutes` (integer minutes). |
+| `rules` | array | auto-rule list. If any rule matches, the IP enters the auto IP group list. |
+| `rules[].name` | string | rule name, only for UI display and error messages. |
+| `rules[].expr` | string | Expr expression, must return a boolean. |
+
+## Execution Semantics
+
+Auto IP groups first aggregate metrics per client IP, then run rule expressions against each IP:
+
+1. The Server reads request logs from the last `lookback` window.
+2. Groups by normalized `remote_addr` IP.
+3. Computes per-IP metrics: request count, 404 count, direct-IP Host count, etc.
+4. Runs `rules[].expr` per IP.
+5. If an IP matches any rule, it is written into the auto IP group's `IP / IP segment` list.
+
+Whether a Host is "accessed via IP" is judged by the `Host` field in request logs: if the Host is an IPv4 or IPv6 literal, e.g. `203.0.113.10`, `[2001:db8::10]`, `203.0.113.10:443`, it counts toward `ip_host_count`.
+
+## Available Keywords
+
+The expression can use these fields directly:
+
+| Keyword | Type | Purpose |
+| --- | --- | --- |
+| `ip` | string | the client IP currently being judged. |
+| `request_count` | number | the current IP's total requests in the lookback window. |
+| `status_404_count` | number | the current IP's requests returning 404 in the window. |
+| `status_404_ratio` | number | 404 ratio, computed as `status_404_count / request_count`. |
+| `ip_host_count` | number | requests where the current IP accessed via an IP-literal Host. |
+| `ip_host_ratio` | number | ratio of IP-address access, computed as `ip_host_count / request_count`. |
+| `client_error_count` | number | the current IP's requests returning 4xx. |
+| `server_error_count` | number | the current IP's requests returning 5xx. |
+| `last_seen_unix` | number | the current IP's last request Unix timestamp (seconds) in the window. |
+
+Ratio fields are decimals between `0` and `1`. 80% is written `0.8`, 50% is `0.5`.
+
+### Custom Status Code Matching
+
+If the built-in `status_404_count` / `status_404_ratio` don't fit, use these built-in methods to match arbitrary status codes:
+
+* **`StatusCount(code)`**: request count of the current IP returning the given status code (or class) in the window.
+  * exact code: `StatusCount(403) > 10`
+  * status class (`1xx`–`5xx`, case-insensitive): `StatusCount("4xx") > 50`
+* **`StatusRatio(code)`**: the ratio of the above count to the IP's total requests.
+  * exact code: `StatusRatio(502) >= 0.5`
+  * status class: `StatusRatio("4xx") >= 0.8`, `StatusRatio("5xx") >= 0.3`
+
+A status class aggregates all codes in that hundred range, e.g. `"4xx"` covers 400–499, `"2xx"` covers 200–299.
+
+## Common Expr Patterns
+
+Auto IP groups use Expr syntax; the expression must return a boolean.
+
+Common operators:
+
+| Pattern | Purpose | Example |
+| --- | --- | --- |
+| `>`、`>=`、`<`、`<=` | numeric comparison | `request_count > 100` |
+| `==`、`!=` | equal / not equal | `ip != "127.0.0.1"` |
+| `&&` | and | `request_count > 100 && StatusRatio(404) >= 0.8` |
+| `||` | or | `StatusRatio(404) >= 0.8 || server_error_count > 20` |
+| `!` | negation | `!(ip == "127.0.0.1")` |
+| `in` | value in list | `ip in ["203.0.113.10", "198.51.100.20"]` |
+| `not in` | value not in list | `ip not in ["127.0.0.1"]` |
+| `()` | grouping precedence | `(request_count > 100 && StatusRatio(404) >= 0.8) || server_error_count > 50` |
+
+## Built-in Presets
+
+The admin panel ships two preset rules that can be added and then adjusted:
+
+```json
+{
+  "name": "Single-IP high-frequency 404 scanning",
+  "expr": "request_count > 100 && StatusRatio(404) >= 0.8"
+}
+```
+
+Meaning: a single IP has over 100 requests in the window and a 404 ratio of at least 80%.
+
+```json
+{
+  "name": "Single-IP direct-access anomaly",
+  "expr": "ip_host_count > 50 && ip_host_ratio > 0.5"
+}
+```
+
+Meaning: a single IP accessed via IP-literal Host over 50 times, and that access ratio exceeds 50%.
+
+## Examples
+
+High-frequency 404 scanning:
+
+```json
+{
+  "lookback": "1h",
+  "rules": [
+    {
+      "name": "High-frequency 404 scanning",
+      "expr": "request_count > 100 && StatusRatio(404) >= 0.8"
+    }
+  ]
+}
+```
+
+IP direct-access anomaly:
+
+```json
+{
+  "lookback": "30m",
+  "rules": [
+    {
+      "name": "IP direct-access anomaly",
+      "expr": "ip_host_count > 50 && ip_host_ratio > 0.5"
+    }
+  ]
+}
+```
+
+Catching both high 4xx and high 5xx:
+
+```json
+{
+  "lookback": "2h",
+  "rules": [
+    {
+      "name": "Abnormal error rate",
+      "expr": "(client_error_count > 80 && request_count > 100) || server_error_count > 30"
+    }
+  ]
+}
+```
+
+Using status-class syntax (equivalent thinking to `client_error_count` / `server_error_count`):
+
+```json
+{
+  "lookback": "2h",
+  "rules": [
+    {
+      "name": "High 4xx or 5xx ratio",
+      "expr": "request_count > 100 && (StatusRatio(\"4xx\") >= 0.8 || StatusRatio(\"5xx\") >= 0.3)"
+    }
+  ]
+}
+```
+
+Excluding trusted IPs:
+
+```json
+{
+  "lookback": "1h",
+  "rules": [
+    {
+      "name": "404 scanning excluding trusted IPs",
+      "expr": "ip not in [\"203.0.113.10\", \"198.51.100.20\"] && request_count > 100 && StatusRatio(404) >= 0.8"
+    }
+  ]
+}
+```
+
+## Usage Tips
+
+Start with a shorter lookback and higher thresholds to observe hits, then tune gradually. The admin IP group page supports clicking **Test Rule** before saving to directly view the IPs hit in the current window; when the auto IP group actually runs, it overwrites the group's IP list. To keep certain addresses long-term, put them in a manual IP group and reference both the manual and auto groups in the WAF rule group.
+
+Auto IP group updates don't require republishing a config version. Online Agents receive the changed IP groups via WebSocket and update the local `waf_ip_groups.json`; when the WebSocket is unavailable, the Agent reports the local IP group checksum in the next heartbeat and the Server only returns the groups whose checksums differ.

+# WAF Security Protection
+
+OpenFlare WAF orchestrates rules with a visual directed acyclic graph. When creating a rule you only enter a name; the system creates the default "start → pass" graph and enters the editor.
+
+## Nodes and Connections
+
+- **Start**: unique per rule; enters the graph along `next`.
+- **Pass**: ends the current rule; if the route has more rules, execution continues.
+- **Block**: immediately terminates the request with the configured status code and HTML response.
+- **IP match**: configure an IP, CIDR, or IP group; connect `true` / `false` respectively.
+- **Geo match**: branch by country or ISO 3166-2 first-level division code; the country list shows both localized names and codes; divisions are searchable by country name, division name, or code. Country and City MMDB are provided by disk files (Docker images COPY them to the default path; bare binaries download from the configured URL on first startup) and update on the configured cycle. When City MMDB is unavailable, it is treated as no match.
+- **PoW**: takes over the request when the challenge is incomplete; after verification passes, continues along `next`.
+
+The server rejects cycles, dangling outlets, unreachable nodes, duplicate port connections, and invalid configs. Save carries the `revision` obtained at page load; on a 409 conflict, reload to avoid overwriting others' changes.
+
+Select a normal node or edge, then click the delete button at the canvas top-right, or press Delete/Backspace. Deleting a node also deletes associated edges; the single "start" and "pass" nodes cannot be deleted. Dragging a node only records the final coordinates on release; the canvas state is not rebuilt repeatedly during movement.
+
+The right node property panel is hidden by default and shows after clicking a node; it auto-collapses when clicking an edge or blank canvas.
+
+The orchestration area defaults to a compact height and smaller initial zoom; you can still zoom freely with the wheel or canvas Controls.
+
+## Binding and Effect
+
+Enabled global rules always execute first; route-bound custom rules execute strictly in list order. After adjusting the order, you must publish a config version for the rule topology to take effect with the OpenResty reload.
+
+IP group members are dynamic resources. The Agent checks the checksum every 5 seconds and updates in-memory snapshots across workers on change — no rule republish or reload needed. Manual, subscription, and auto IP groups can all be referenced by IP-match nodes. A single full IP group runtime snapshot is capped at 20 MiB; exceeding the cap makes publish or sync return an error and keeps using the previous valid snapshot.
+
+> [!IMPORTANT]
+> When upgrading from the legacy fixed allow/block-list, geo, or PoW forms, rule graphs reset to "start → pass" and old policy fields are not migrated. Re-orchestrate and verify each rule before publishing a new version.

+# Zone Domain Migration and Release Acceptance
+
+When migrating from the legacy `managed_domains` / inline domain columns of reverse proxy routes to the Zone + Zone Domain model, data import and table structure upgrades are both completed by the **automatic goose migration at Server startup** — no separate import command is needed.
+
+## What Happens During Upgrade
+
+When starting (or rolling-upgrading) a Server version that includes the Zone rework, **no manual command is required**; `migrator.Migrate()` automatically:
+
+1. Applies goose SQL: creates `of_zones` / `of_zone_domains` (if they do not yet exist).
+2. **Automatically imports** the legacy route domain columns (and `of_managed_domains` when routes have no domains) as Zone / Zone Domains, binding `proxy_route_id` / `cert_id` (registering root domains via public suffix list parsing).
+3. Continues goose SQL: drops the redundant domain/certificate columns from `of_managed_domains` and `of_proxy_routes`.
+
+The import is idempotent: existing domains are skipped or have their route binding back-filled.
+
+**If historical data cannot be parsed (conflicting domains, invalid root domains, missing certificates, etc.), startup fails.** Fix the data or restore a backup and start again to retry.
+
+## Recommended Actions
+
+### 1. Back Up Before Upgrading
+
+```bash
+# PostgreSQL example
+pg_dump "$DATABASE_URL" > openflare-pre-zone-$(date +%Y%m%d).sql
+
+# Or copy the backup volume / snapshot; for SQLite, copy the database file in the data directory
+```
+
+Optional: note down the current **active config version number** and checksum in the admin panel for config rollback comparison.
+
+### 2. Upgrade and Start the Server
+
+Deploy the new version and start it. Watch the goose success messages in the startup log; if "Zone migration failed (N conflicts)" appears, fix the source data according to the conflicts listed in the log and restart.
+
+### 3. Post-Upgrade Checks
+
+1. Admin panel **Websites** `/websites`: check whether Zone root domains and domain counts are reasonable.
+2. Zone details: domains, certificates, associated route IDs.
+3. **Reverse proxy routes**: domain bindings come from Zone Domains, not legacy hand-written fields.
+
+### 4. Config Preview and Release
+
+1. Review the config diff / preview in the admin panel.
+2. Verify **per route**: `server_name` set, certificate paths, WAF Route ID, Pages references.
+3. **Allow** the redundant `domain` / `domains` / `cert_ids` on routes in old snapshot JSON to disappear.
+4. **Do not allow** data-plane semantic changes.
+5. After the preview passes, release it; if needed, activate the pre-upgrade version in config versions for config rollback. For database rollback, use the pre-upgrade backup (down migrations do not backfill business domain data).

+- **Config file**: reads `config.yaml` in the same directory at startup by default (overridable via the `CONFIG_PATH` env var).
+- **Env vars**: every field in the config file can be overridden by an `UPPER_SNAKE_CASE` env var (env vars take precedence over `config.yaml`).
+- **System runtime config**: stored in the `w_system_configs` table in the relational DB. These can be hot-updated and take effect dynamically via the admin UI or system API.
+
+### 2. Agent / Relay / OpenFlared Config Sources
+- **CLI args**: `-config` specifies the config file (JSON format).
+- **Config file**: e.g. `agent.json`, `relay.json`, `flared.json`.
+- **Override env vars**: specific env vars can override connection addresses and Token credentials in the config file.

-输入 `.exit` 退出并重新启动 Server。
 
-#### 2. 若使用 PostgreSQL 数据库
-通过您的数据库连接工具（如 psql、pgAdmin 或 DBeaver）连接到 PostgreSQL 实例，选择对应的 `openflare` 数据库，执行以下 SQL 语句：
-```sql
-UPDATE users SET password = '$2a$10$eXpE9i/6S3gPT94/G0mu0.B8ser66ARETFz5NWYSYcrQ4JmtSrMXu' WHERE username = 'admin';

-执行成功后即可使用默认密码 `12345678` 重新登录管理后台。
+若使用 SQLite，建议先停止 Server 进程再执行，避免数据库文件锁冲突。未指定 `--password` 时命令会生成随机密码并输出到终端。重置成功后请立即登录并修改密码。
