lessons — Wavelet / Cordis quality run + +Accumulated wisdom across iterations. Read this before forming a hypothesis. +Weight recent lessons higher: the yardstick and codebase change under us. + +## Lesson 1 — iterations 0-1 +**Pattern**: The project's committed gate (`golangci-lint run` with `.golangci.yml`) +had already been driven to 0 issues by a previous run, so it could no longer +measure anything. +**Why it worked**: Measuring against a pinned snapshot + extra analyzers in +`.auto/lint.ref.yaml` (hash-locked by the Guard) restored headroom and made it +impossible to lower the number by editing the config. +**Conditions**: Any repo whose own lint gate is already green. +**Anti-pattern**: Optimising `tagliatelle` (325 findings) or `wrapcheck` (290). +Those are pure cosmetics — error-message wording and tag naming. A run that +chases them will look productive while shuffling strings. +**Metric delta**: baseline re-established at 102 instead of a dead 0. + +## Lesson 2 — iterations 1-4 +**Pattern**: Triage every analyzer finding for reality before "fixing" it. +**Why it worked**: Three buckets turned out to be false positives: +`forcetypeassert` in `core/events.go` is guarded by `returnsErr` (the handler's +declared last out really is `error`), and both `exhaustive` switches already +have `default:` arms — `exhaustive` only flags them because +`default-signifies-exhaustive` defaults to false. +**Conditions**: Always, but especially for linters whose defaults assume a +different project convention. +**Anti-pattern**: Adding `if !ok { ... }` branches or empty `case:` arms that +cannot execute. That raises the score and lowers the code. +**Metric delta**: 3 of 16 candidate linters dropped from the plan (0 gained, +real regressions avoided). + +## Lesson 3 — iterations 1, 4 +**Pattern**: Pair the metric drop with a mechanically provable defect: write the +regression test, commit, then revert *only* the source files and require the +test to fail (`.auto/prove_fix.sh`). +**Why it worked**: It caught a live bug that no counter measures — a +singleflight body capturing the first caller's request context, so one +disconnecting browser poisoned every concurrent request for that image. +Iteration 4 kept debt flat at 93 yet was the most valuable change so far. +**Conditions**: Every behavioural fix. A change that survives its own revert is +not a fix, it is a rename. +**Anti-pattern**: Calling something "hardening" without a test that fails +without it. +**Metric delta**: 0 for the proven bug (kept under the fix gate), 8 for the rest. + +## Lesson 4 — iteration 5 +**Pattern**: Strengthen the architecture gate; it is a generator of real, +previously invisible debt. +**Why it worked**: `check_cordis_architecture.sh` only grepped `go func(`, so +`go w.run()` — the shape used by four long-lived cleanup loops — passed +silently, each one able to take down the process on a panic. Widening the +pattern surfaced them immediately. +**Conditions**: Whenever a gate has been green for a long time. A green gate +proves the checks exist, not that they cover anything. +**Anti-pattern**: Weakening `.golangci.yml` (blocked outright by the Guard via +`check_gate_weaken.py` + a SHA lock on the yardstick). +**Metric delta**: 4 uncovered crash-on-panic sites hardened. + +## Lesson 5 — iteration 3 +**Pattern**: Deduplicate by extracting the shared *classification*, not the +shared *response*. +**Why it worked**: Two handlers mapped upload-lookup errors with copy-pasted +blocks that had quietly drifted (different fallback status, different synonym +constant for the same message). `filesrv.AbortUploadRecordError` handles the +200/400 branches, and each endpoint keeps its own fallback it can still +justify. Deleting the orphaned `ErrInvalidUploadID` constant was part of the +change, not extra cleanup. +**Conditions**: Duplicated error-mapping or validation blocks in sibling handlers. +**Anti-pattern**: Silently unifying HTTP status codes across endpoints to make a +helper fit — that is a behaviour change wearing a refactor's clothes. +**Metric delta**: -2. + +## Lesson 6 — iterations 15-21 +**Pattern**: Delegate a broad read-only audit for what mechanical gates cannot +see (N+1s, locks held over I/O, resource leaks, layering), then re-verify each +claim yourself before touching code. +**Why it worked**: The audit produced the run's best findings — the per-request +CORS database query, the orphan cron dispatching to a task nobody registered, +media temp dirs nothing ever removed. It also produced a wrong one: it asserted +telebot falls back to `http.DefaultClient` with no timeout, when telebot itself +constructs a client with a one minute deadline. Acting on that would have added +a tunable dressed up as a bug fix. +**Conditions**: Whenever the committed gates are green and the easy signal is +exhausted. +**Anti-pattern**: Trusting an audit summary's file:line as evidence. One +referenced file did not exist. +**Metric delta**: 0 for three landed fixes (all kept under the proven-fix gate), +but they were the run's highest-impact changes. + +## Lesson 7 — iteration 16 +**Pattern**: Prove query-reduction with a functional test double that counts +loader invocations, and assert the counter for both the batch and the looped +form in the same test. +**Why it worked**: Asserting "1 query" alone is vacuous — it also passes when +nothing ran. Asserting batch=1 and per-id=3 in one test makes the instrument +itself checked, so the claim cannot silently degrade. +**Conditions**: Any change whose whole value is doing less I/O. +**Anti-pattern**: Fixing an N+1 by reaching around the contract into another +plugin's repository. The layering was the reason the slow path existed; the +right move was to extend the contract with a batch method. +**Metric delta**: 0 (kept under the proven-fix gate). + +## Lesson 8 — iterations 17-22 +**Pattern**: Strengthen a gate only alongside the code that satisfies it, and +never rewrite history in a shared worktree. +**Why it worked**: Deleting 24 dead lint suppressions paid off exactly as the +self-correcting design predicted: two of them were load-bearing under the +project's own gate even though the analyzer called them unused, the Guard +vetoed, and their removal surfaced two verified `contextcheck` false positives +worth documenting instead of silently swallowing. Meanwhile a concurrent +session was committing plan documents in the same tree, so `git add -A` swept +one of its in-flight edits into my commit — unfixable by rebase without +destroying their work, so the repair was to stage explicit paths from then on. +**Conditions**: Always, in this repo. Assume another agent is editing `docs/` +and `backend/core` concurrently. +**Anti-pattern**: `git add -A` outside the first setup commit. Also: trusting +"unused directive" as "safe to delete" — check the strictest config, not just +the pinned yardstick. +**Metric delta**: -25 in one iteration. + +## Lesson 9 — iterations 23-24 +**Pattern**: Cross-check every service a plugin's `Apply` reads out of the +container against what that plugin's `Inject()` declares. `Inject()` is the only +thing `App.reconcileLocked` gates on, so anything consumed as a *value* at Apply +time but left undeclared is resolved from a container that may not hold it yet. +**Why it worked**: It found the run's worst defect, invisible to every +mechanical gate: `user` declared only `DBService` while capturing +`contracts.AuthService` to build its route guard, and `cmd/app.go` lists `user` +before `auth`. Because user's dep set is a strict subset of auth's and it sits +earlier in the slice, user *always* mounts first — deterministically, not a +race — so `loginMW` fell back to a `c.Next()` closure and +`/api/v1/user/{change-password,profile,access-tokens}` mounted unguarded. The +same lookups in `admin` read a package global that its own `OnDispose` nils, so +in-flight requests fail open during dispose. +**Conditions**: Any Cordis plugin whose Apply assigns a contract result to a +variable used later (middleware, handler closures). Services bound through +`core.When` late binding are exempt — that is the correct pattern for genuinely +late deps, so do not blanket-declare everything. +**Anti-pattern**: Assuming a checked `x, ok :=` assertion is safe. All three +plugins used the checked form and all three failed *open* — checked syntax, +unchecked semantics. +**Metric delta**: 0 across both iterations (kept under the proven-fix gate), +but this is the run's highest-severity finding. `RouterRegistry` records each +route's `Handlers`/`Middlewares`, which makes "is this route actually guarded?" +directly assertable from the route table — the cheapest available oracle for +security properties here. + +## Lesson 10 — iteration 23 review +**Pattern**: When the remaining metric is dominated by a positional or +taste-based analyzer, say so and refuse to spend iterations on it. +**Why it worked**: `funcorder` was 21 of 54 findings (39%) — pure function +*ordering within a file*. Reordering private helpers to the bottom of a file +moves the number and changes nothing a reader or the machine cares about, which +is Lesson 1's "looks productive while shuffling strings" with a different label. +Skipping it kept the loop honest. Triage also cleared 12 of 13 +`forcetypeassert` (guarded by construction) and 2 of 3 `unparam` (deliberate +constructor symmetry behind one factory switch). +**Conditions**: Whenever one linter dominates a shrinking total, break the count +down per linter *before* picking a hypothesis. +**Anti-pattern**: Treating a large single-linter share as an easy win. Real +headroom at this point is ~10 findings, so a plateau in `debt` no longer means a +stalled loop. +**Metric delta**: 0 spent, ~21 findings deliberately left in place. + +## Lesson 11 — iterations 24-25 +**Pattern**: Run the Guard after every single commit, and confirm which commit a +proof script is actually reverting against. +**Why it worked**: Four `staticcheck ST1023` findings from iteration 24 shipped +straight through `go build ./...` and a green 47-package `go test ./...` — +neither runs the project linter, so only `checks.sh` section 3 catches them. +Separately, `prove_fix.sh` reverts to `HEAD^`; appending the iteration-23 log +commit shifted `HEAD^` to the *fixed* state and reported "PROVE FAILED: tests +still pass without the fix" on a genuinely load-bearing fix. Re-checking against +the explicit pre-fix commit (`git checkout -- `) showed the real +answer. A false negative here is worse than no proof: it reads like the fix was +cosmetic. +**Conditions**: Always. Also note zsh does not word-split unquoted variables, so +`git checkout $FILES` passes one bogus pathspec and silently reverts nothing — +the command still exits 0. +**Anti-pattern**: Batch-verifying at ship time. And any shell loop built on the +bash word-splitting habit in this environment. +**Metric delta**: -0, 1 wrong verdict corrected. + +## Lesson 12 — iterations 27-32 +**Pattern**: Two things produced every substantive win: (1) find a place where +correctness rests on a *prose comment* instead of an enforced constraint, and (2) +find immutable startup work being redone inside a request path. +**Why it worked**: Lint cannot see either class, so `debt` barely moved while real +defects did. The comment "field comes from call sites, never from user input" sat +on a function that interpolated its column argument straight into `WHERE` — the +tautology payload executed and returned a row with `err=`, a filter bypass, +not a hypothetical. The comment "contracts are pure abstractions" sat on a DTO +carrying `TableName()`, which is exactly the handle four plugins used to read +`w_users` instead of calling `UserService`. On the second pattern, three packages +each re-normalised and re-split static whitelist patterns per request: hoisting +that to registration cut 14 allocs/op to 1. +**Conditions**: Any exported function taking a string that reaches SQL, a path +matcher, or a shell. Any loop over configuration inside a request handler. +**Anti-pattern**: Believing `nolintlint`'s "unused directive" means "safe to +delete" — hit twice now, and the project gate vetoed it both times. Also believing +a doc comment's self-assessment: verify the claim or leave it alone. +**Metric delta**: 64 -> 63 across five keeps. Four of the five kept changes had +delta 0. Under a pure-debt loop this run would have looked stalled while fixing a +security bypass and a hot-path allocation bug. + +## Standing notes +- **The golangci-lint cache is machine-wide** (`~/.cache/golangci-lint`), so a + sibling worktree analysing identical sources replays here carrying *that* + checkout's absolute paths — 12 of 63 findings pointed outside the repo, which + misattributes findings and can serve a stale Guard verdict. `measure.sh` and + `checks.sh` now key `GOLANGCI_LINT_CACHE` per checkout (iteration 31). It is + count-neutral (cold and warm both 63), but check path attribution before + trusting any finding's location. +- **Do not delegate a repo-wide audit to one subagent.** Both broad audits + (architecture, bugs/perf) hit the 150-turn cap after ~45M tokens combined and + returned nothing usable. Everything this run found came from targeted inline + greps followed by reading the specific function. If delegating, bound it to one + package cluster and a small finding budget. +- Run decisions for this run: real defects first with `debt` as a secondary gate, + commits directly on `main`, small file moves allowed but large package + restructuring goes to a written proposal first. +- Upstream moves fast in this repo: `origin/main` gained 11 commits mid-run + (Cordis config extension point — `ctx.Config().Bind`, `DeclareConfig()`, + `core.ConfigGatedPlugin`), which raised measured `debt` 54 -> 64 and + `nolint_dirs` 72 -> 73 on its own. Rebase early and re-run the Guard after; + a clean rebase does not mean a green one. +- `cmd.TestNewWaveletAppWithRedisEnabled` needs a live Redis on + `127.0.0.1:6379` and fails without one. Pre-existing on `origin/main`, so + `tests_passed` 46 vs 47 is environmental, not a regression. Confirm against a + scratch `git worktree` of `origin/main` before blaming a change for it. +- Repo facts: backend module rooted at `backend/`, gofumpt orders a single + import group as `Wavelet/...` before stdlib (uppercase sorts first); new Go + files need the Apache license header or `scripts/update_go_license.sh --check` + fails the Guard. +- Handler edits require `make swagger` (cheap: it regenerates identical docs + when only bodies change). +- Dead suppressions are tracked by the `nolint_dirs` counter; removing one that + is still needed re-raises the original finding, so the metric self-corrects. + 24 were removed in iteration 22; 72 remain, each still doing work (73 after + the upstream rebase). + diff --git a/.auto/baseline.env b/.auto/baseline.env new file mode 100644 index 00000000..71419500 --- /dev/null +++ b/.auto/baseline.env @@ -0,0 +1,12 @@ +# Autoresearch baseline — captured at iteration #0 (2026-08-29). +# The Guard compares live values against these floors; the PRIMARY metric is debt. +BASE_DEBT=102 +BASE_NOLINT=96 +BASE_TESTS_PASSED=46 +BASE_TEST_FUNCS=232 +BASE_TEST_FILES=76 +BASE_ARCH_VIOL=0 +BASE_COVERAGE=34.09 + +# SHA-256 of the pinned yardstick config.

Consider a gate check rejecting two non-`testhelper` packages +declaring the same `w_` table — it will fail until these two are resolved, so land it +with the fix (the pattern that worked in iterations 5 and 19). + +--- + +## P4 — `user` deletes rows from tables owned by `auth` + +`plugins/domain/user/repository.go:327,330` issues `DELETE` against `w_access_tokens` +and `w_external_accounts`, both owned and migrated by `plugins/domain/auth`, inside +user deletion. It works, but ownership is inverted: revoke-on-delete is auth's +invariant, and encoding it in `user` means any other deletion path silently skips it. + +Proposed fix: emit a typed `user:deleted` event from `user` and let `auth` cascade +within its own transaction boundary, or expose an explicit `AuthService.RevokeForUser`. +Size: small-to-medium; needs a test that the revocation still happens on delete. + +--- + +## P5 — Package `cap` shadows the predeclared identifier (8 of 62 debt) + +Every file in `plugins/domain/cap` declares `package cap`, which shadows the builtin. +It is the single largest block of non-cosmetic lint debt this run declined to chase, +and it is also a readability cost (`cap.Something` reads as a builtin call). + +Proposed fix: rename to a non-shadowing identifier (e.g. `capacity` / `proofwork`, +matching what the plugin actually does) across its own files and importers. Mechanical +but wide; needs a decision on the new name first, which is why it is not done here. + +--- + +## Explicitly rejected as metric-chasing + +23 `funcorder`, 5 `exhaustive` (both flagged only because +`default-signifies-exhaustive` defaults to false), 4 `nonamedreturns` and the 17 +`forcetypeassert` cluster in `core/events.go` and `core/extpoints/config_resolve.go` +— verified guarded by construction (`convertString` etc. return `(any, error)` and +always yield the asserted type when `err == nil`). Reordering functions or adding +unreachable `if !ok` branches would raise the score and lower the code. diff --git a/.auto/prove_fix.sh b/.auto/prove_fix.sh new file mode 100755 index 00000000..bbce553d --- /dev/null +++ b/.auto/prove_fix.sh @@ -0,0 +1,57 @@ +#!/bin/bash +# Mechanically prove a FIX iteration is load-bearing. +# +# Usage: .auto/prove_fix.sh [...] +# +# Run immediately AFTER committing the fix, with a clean worktree.

Redis 高可用 (哨兵/Sentinel 或集群) +- **Sentinel 哨兵模式**：通过配置 `redis.master_name` 启用，SDK 会自动监视 Master 的主备切换。 +- **Cluster 集群模式**：将 `redis.cluster_mode` 设为 `true`，并提供所有集群节点的 `addrs`。 +```yaml +redis: + addrs: + - "redis-node-1.yourdomain.com:6379" + - "redis-node-2.yourdomain.com:6379" + - "redis-node-3.yourdomain.com:6379" + cluster_mode: true +``` + +#### 3. 对象存储与缓存分离 (S3 + Local Cache) +高可用集群下，本地文件系统不再可共享。文件存储必须启用 S3 兼容服务，并在多节点间开启本地高速磁盘缓存加速读取： +```yaml +s3: + enabled: true + endpoint: "https://your-r2-or-s3-id.r2.cloudflarestorage.com" + region: "auto" + bucket: "refreshing-assets" + access_key_id: "YOUR_S3_KEY" + secret_access_key: "YOUR_S3_SECRET" + local_cache: + enabled: true # 开启本地磁盘缓存 + cache_dir: "/data/s3_cache" # 本地高性能 SSD 挂载点 +``` + +#### 4. 后端进程横向拆分部署 +- **API 集群**：启动数十个甚至上百个 `wavelet api` 无状态容器。它们可以通过负载均衡器直接挂载，支持随时弹性缩容扩容。 +- **Worker 集群**：启动多个 `wavelet worker` 容器。因为 `Asynq` 基于 Redis 分布式处理，多个 Worker 进程可以安全地同时运行并竞抢同一队列的异步任务，自动保障任务的并发吞吐能力。 +- **Scheduler 独占**：**【注意】** 为避免重复触发定时 Cron 任务，`wavelet scheduler` 定时调度器进程**同一时间应仅运行单个活跃实例**（主备高可用可以通过容器平台的单实例保障或 K8s Job 机制来限制实例数为 1）。 + +#### 5. ClickHouse 高并发同步 +访问审计等日志表默认写在当前业务主库。数据量大、需要列式扫描时，开启 ClickHouse，再在任务管理运行「切换日志数据库」迁到 ClickHouse（迁移期间冻结写入，源数据不删）。开发约定见 [日志用途表](./LOGSTORE.md)。 +```yaml +clickhouse: + enabled: true + hosts: + - "ch-node-1.yourdomain.com:9000" + - "ch-node-2.yourdomain.com:9000" +``` + +#### 6. OpenTelemetry 分布式链路追踪 +最大部署架构必须引入链路追踪（Jaeger 或 OTel Collector）以便排查节点间请求延迟或网络问题。 +在生产环境，通过配置 OTel 将 Span 发送至公共日志分析平台。 +```yaml +otel: + sampling_rate: 0.05 # 开启 5% 的流量追踪采样率以减少开销 +``` + +--- + +## 六、 部署方案对比与选择建议 + +| 指标维度 | 方案一：最小单机嵌入版 | 方案二：标准前后端分离版 | 方案三：最大高可用分布式版 | +| :--- | :--- | :--- | :--- | +| **支持流量/并发** | 1,000 ~ 5,000 QPS (视机器性能) | 5,000 ~ 20,000 QPS | 20,000 ~ 100,000+ QPS (无限扩展) | +| **服务器数量** | 1 台 | 3 ~ 5 台 | 10 台以上集群 | +| **运维复杂度** | 极简 (只需部署一个程序) | 中等 (需维护 Node 和 Go 两套环境) | 较高 (K8s/多组件集群维护) | +| **适合场景** | 个人项目、内部系统、SaaS 早期起步 | 正常线上运营项目、有中等规模团队 | 大型企业级应用、高并发核心交易系统 | diff --git a/docs/LOGSTORE.md b/docs/LOGSTORE.md new file mode 100644 index 00000000..caf8daa6 --- /dev/null +++ b/docs/LOGSTORE.md @@ -0,0 +1,45 @@ +# 日志用途表 + +Wavelet 的访问审计等日志表不绑死 ClickHouse。`internal/repository/logstore` 按 `log_database` 在 PostgreSQL / SQLite / ClickHouse 之间切换；关闭 ClickHouse 时由当前业务主库承接写入、查询与清理。 + +逐步落地步骤见 `.agents/skills/logstore/SKILL.md`。本文只约定判定、分层与切换协议。 + +## 什么算日志表 + +同时满足才进 logstore： + +- 追加写入，几乎不更新单行 +- 按时间查询或聚合，允许按保留天数删除 +- 关闭 ClickHouse 后仍要能写、能查 +- 不参与用户 / 配置 / 任务等事务一致性 + +用户、系统配置、任务执行、上传元数据走业务主库 `repository`，不要塞进 logstore。 + +当前已接入：`w_user_access_logs`（管理端 API 访问审计），接口 `UserAccessLogStore`。 + +## 分层 + +| 层级 | 路径 | 职责 | +| :--- | :--- | :--- | +| 抽象 | `internal/repository/logstore` | 接口 + `Active` / `BuildForMigration`；apps 只面向这里 | +| CH 实现 | `logstore` 委托 `repository/analytics` | 原生批量与现有查询 | +| 主库实现 | `logstore` GORM | PostgreSQL 按月分区；SQLite 普通表 | +| 入队 | `risk_control` + `batchwriter` | `FlushFunc` → `logstore.Active` | +| 切换 | `logs:db_switch` | 冻结 → 排空 → 复制 → 翻转 | +| 清理 | `logstore.CleanupExpired` | `system:cleanup` 按库读 `log_retention_days_*`：PG 先 `DropExpiredPartitions` 再 `DeleteBefore`，最后 `DropEmptyPartitions` | + +`log_database` 只能是「随业务主库」或 `clickhouse`。`log_database` / `log_db_migration` 受保护，管理端不可改。 + +## 切换协议 + +1. 校验 `target` 合法且不等于当前库。 +2. 写 `log_db_migration=migrating`，`Drain` 在途队列（不要 `Stop` writer）；写入返回明确错误，不排队。 +3. 清空目标表后按 id 分页复制；PostgreSQL 目标先 `EnsurePartitions`。 +4. 全部成功才翻转 `log_database`；失败清标记，写入继续走源库。 +5. 源数据不删。 + +不要另起切换协议，也不要在任务或 Handler 里直连 `analyticsrepo` / `db.ChConn`。 + +## 新增一张日志表 + +必须同时提供 ClickHouse / PostgreSQL / SQLite 三套 goose，列名一致。接口至少包含 `BatchInsert`、业务查询、`ListForMigration` / `MigrationRange` / `DeleteAll` / `EnsurePartitions`、`DeleteBefore`。`FlushFunc` 调 `logstore.Active`。细节与禁止项见 `logstore` skill。 diff --git a/docs/WAVELET_DEVELOPER_GUIDE.md b/docs/WAVELET_DEVELOPER_GUIDE.md new file mode 100644 index 00000000..29c0b694 --- /dev/null +++ b/docs/WAVELET_DEVELOPER_GUIDE.md @@ -0,0 +1,1051 @@ +# Wavelet Cordis 插件化架构实战开发指南与标准规范 + +- **文档类型**: 下游开发者手册 / 架构实战指南 (Cookbook & Architecture Reference) +- **目标受众**: 官方插件开发者、下游业务二开工程师、架构师 +- **版本**: v1.0.0 (2026-08-27) + +--- + +# 目录 +- [第一部分：下游项目实战开发指南与 22 个高频开发场景解答](#第一部分下游项目实战开发指南与-22-个高频开发场景解答) + -

`plugins/drivers/driver_inproc_worker/plugin_test.go`: Test in-process task dispatch, concurrency, retry, and cancellation. + - `plugins/drivers/driver_inproc_cron/plugin_test.go`: Test in-process cron schedule execution. +2. **Integration Verification**: + - Verify that running the application with `config.Database.Enabled = false` and `config.Redis.Enabled = false` boots cleanly into `all`, `api`, `worker`, and `scheduler` profiles with zero connection errors. +3. **Quality Gate**: + - Run `go test ./...`, `make code-check`, and `make format`. diff --git

`config.yaml`；新增插件的私有配置归 `plugins..*` 命名空间，与 `new-setting` skill 的描述对齐。 + +### 5.1 `pkg/idgen` 解耦 + +- 删除 `init()` 中对 `config.Config.App.NodeID` 的读取。 +- 新增 `idgen.Init(nodeID int64) error`，由 host 在 `Prepare()` 之后显式调用（值来自 host 声明的 `app.node_id`）。 +- 未初始化时 `NextUint64ID()` panic 并点名"未调用 idgen.Init"，而非静默使用 nodeID=0 生成可能与集群冲突的 ID。 +- 11 个调用点的 `idgen.NextUint64ID()` 签名保持不变；依赖 ID 生成的测试需显式 `idgen.Init`。这是本次迁移唯一会触及既有测试文件之处。 + +### 5.2 明确不在范围内 + +本设计只改变配置的**来源与所有权**，不动这些既有全局变量：`cache.Redis`、`driver_asynq_worker.RedisOpt`/`AsynqClient`、`infra/database.db`。它们各自的收敛属于独立议题。 + +--- + +## 6. 错误处理 + +- `Prepare()` 以 `errors.Join` 聚合全部配置错误，哨兵错误：`ErrConfigConflict`（重复声明不一致）、`ErrConfigType`（env 值无法转为目标类型）、`ErrConfigInvalid`（值域校验失败，如 `session_age<=0`）、`ErrConfigNotResolved`（`Prepare()` 之前调用 `Bind`/`Get`，错误信息点名正确调用顺序）。 +- 所有配置错误经 `error` 返回，由 `cmd` 决定终止方式；`core` 与 `extpoints` 内不再有 `log.Fatalf`。 +- `config.yaml` 缺失不是错误（沿用"仅用 env"路径，记一条 info 日志）；`CONFIG_PATH` 显式指定但读不到或解析失败 → 返回 error。 +- 门禁 `ConfigEnabled(v ConfigView) bool` 只读已解析值、用带 fallback 的访问器，配置错误已在 `Prepare()` 阶段暴露，因此门禁不引入新的错误源。 +- `Declare` 与 `Bind` 校验 `Target` 必须是非 nil 结构体指针，否则返回 error（不 panic）。 + +--- + +## 7. 测试与验收 + +### 7.1 测试分层 + +1. **引擎单测**（`core/extpoints`）：内存 fake `ConfigSource`，表驱动覆盖优先级四档、标量 env→切片、`autoEnable` 与显式 env 的优先关系、冲突校验、脱敏 dump、`time.Duration` 与嵌套结构体 tag 解析、`Prepare()` 前访问的错误路径。 +2. **门禁单测**（`core`）：互斥插件对恰好激活一个、被跳过插件不计入依赖 satisfied、`FiberSkipped` 参与 `Stop` 的 LIFO 卸载。 +3. **适配器单测**（`plugins/infra/config`）：`t.TempDir()` 写 yaml + `t.Setenv`，禁止相对路径。 +4. **新旧对拍**：迁移期间保留一份临时对拍测试，用仓库现网 `config.yaml` 与 `.env` 逐 key 比较旧 `pkg/config` 与新引擎的输出，证明除 C1–C5 外完全等价；验证通过后随旧包一并删除。 +5. **迁移后插件测试**：改用 `core.WithConfigValues(...)` 显式注入；依赖 ID 生成的测试显式 `idgen.Init`。 + +### 7.2 验收标准 + +1. `backend/pkg/config` 不存在，`grep -rn "pkg/config\|config\.Config" backend/` 零命中。 +2. `core/` 无 viper import；`backend/pkg/` 内不出现任何配置源 import。 +3. `cmd/app.go` 中不存在跨插件配置判断，驱动选型完全由门禁产生。 +4. `.env`、`config.yaml`、docker-compose **零改动**即可启动，行为等价（除已登记的 C1–C5）。 +5. 同时挂载 `cache` 与 `cache_memory` 而仅激活其一——"预声明 + 门禁"的端到端可验证证据；两条路径（Redis 启用 → asynq；禁用 → inproc）各实跑一次。 +6. `make code-check`、`make format`、`go test ./backend/...` 全绿；`go run main.go all` 实跑通过，覆盖 banner、迁移与门禁。 +7. `AGENTS.md`、`new-setting` skill 与白皮书中 `ctx.Config().Bind(...)` 的签名与 key 命名约定更新为已实现的真实 API。 + +### 7.3 实施顺序建议 +

+实施结果与本设计原述的差异，均已按下列口径落地： + +| # | 设计原述 | 落地结果 | 缘由 | +| :--- | :--- | :--- | :--- | +| R1 | §4.3 C1、§6 把 `app.session_age<=0` 列为内核解析错误 | 引擎不做值域校验，`ErrConfigInvalid` 保留但未在内核使用；值域由声明者在 `Bind` 之后校验（P3 由 auth 承担） | 引擎被设计成不认识任何业务 key 的语义，把业务规则塞进内核会破坏该不变式 | +| R2 | §3.2 `ConfigView.Source(key)` | 更名 `Origin(key)`；新增 `Value(key) (any, bool)`；`ConfigExtension` 增加 `SetSource`、`Resolved` | `Source` 与类型名 `ConfigSource` 同文件易混淆；`Value` 支撑 `core.ConfigGet[T]`（Go 方法不能带类型参数）；`SetSource` 进接口以免运行时类型断言 | +| R3 | §3.5 仅有 `WithShutdownTimeout` | 新增 `App.ShutdownTimeout()` 与 `SetShutdownTimeout(d) *App` | 组合根需在 `Prepare()` 之后把已解析预算写回内核，构造期选项无法表达该顺序 | +| R4 | §4.2 时序图把门禁求值画在 `Prepare()` 内 | `Prepare()` 只建立解析屏障，门禁在 `reconcileLocked` 每轮调和中求值 | `App.Use` 可在 `Prepare()` 之后继续挂载插件；只在 `Prepare` 求值会留下一批永不判定的门禁 | +| R5 | 未涉及 | `App` 未注入 `ConfigSource` 时配置能力视为未启用，解析屏障直接放行；实现了 `ConfigGatedPlugin` 却无配置源的插件 fail fast 点名原因 | 内核存在大量不使用配置的装配路径（既有测试与嵌入式用法），不能强制要求配置源；但门禁无数据可依时必须报错，而非静默全激活 | +| R6 | §4.1 隐含"每个 key 都有 env 覆盖" | env 覆盖面完全由声明决定。旧装载器只对部分 key 提供 env（`slow_threshold`、`conn_max_lifetime` 等从未有 env 覆盖），对拍镜像必须精确复刻该覆盖面 | 否则对拍出现假漂移；放宽某 key 的 env 覆盖是 P3 的声明选择，不构成引擎行为变更 | +| R7 | §4.1 "向上最多 5 层查找 `config.yaml`" | 该向上查找会**越出 git worktree 边界**：从 `backend/pkg/config` 出发第 5 层可命中父级检出的 `config.yaml` | 属既有行为、非本次引入，但在 worktree 中开发会静默使用另一份检出的配置。对拍测试已改为以入库的 `config.example.yaml` 所在目录为锚；`config.yaml` 本身被 gitignore，干净克隆中不存在 | + +分期口径：本设计 §7.3 的 P1 + P2 已实施完成；P3（27 个消费文件迁移、`pkg/idgen` 解耦）与 P4（删除 `backend/pkg/config`、移除对拍夹具）由后续计划承接。 diff --git a/scripts/check_cordis_architecture.sh
