Root cause: display-only cloud library filtering was reused by scan jobs, merged cloud mounts could be skipped, and OpenList listing relied on WebDAV/first-page behavior that could cap huge directories around 100 items. Cloud scans also let new items consume probe budget before existing rows with missing track/artwork metadata.\n\nChanges:\n- split display filtering from scannable cloud filtering so merged cloud mounts still scan\n- add OpenList API pagination with WebDAV fallback\n- prioritize existing cloud media missing metadata before new imports\n- restrict automatic cloud sync to one successful 19:00-21:00 daily window and keep manual scan immediate\n- disable startup cloud full-scan by default, with an explicit opt-in setting\n- improve Emby/cloud playback compatibility and cache/search/test coverage from the continued work
Three regressions reported on third-party clients and the web UI:
- Third-party clients (Emby/Jellyfin) dropped login / could not play /
could not refresh the library, roughly hourly. The Emby
AuthenticateByName response returned the 60-minute access token, but
Emby clients have no refresh mechanism and reuse the AccessToken until
logout. Issue a long-lived (30d) token for the Emby compat layer via
AuthService.IssueEmbyToken so device sessions persist.
- Web could be thrown back to login under load: /auth/refresh was inside
the IP rate-limited /auth group, so multiple users/tabs behind one
reverse-proxy/NAT IP exhausted the budget and refresh failed -> logout.
Only login/register are rate-limited now (raised to 30/min for shared
IPs); refresh is excluded (already protected by a one-time refresh token).
- Posters/images stopped displaying on the web home and other pages
(refresh did not help). The SSRF/path hardening (a) blocked the image
proxy whenever a hostname *resolved* to a private IP, which happens
under GFW DNS poisoning of public CDNs like image.tmdb.org, and (b)
restricted local image reads to data/cache/movies/tv/anime dirs only,
dropping sidecar posters stored under arbitrary per-library roots to a
placeholder. isPrivateHost now only blocks literal private/loopback IPs
(real SSRF vectors) and ImageProxy also allows reads under configured
library roots.

- Add isPrivateHost() to block image proxy requests to loopback/private/
link-local IPs (SSRF mitigation)
- Add isAllowedLocalPath() to restrict local file reads to configured
data/cache/media directories only
- CORS middleware now takes debug flag; wildcard only when debug=true,
production omits headers (same-origin enforced)
- Add per-IP sliding-window rate limiter (10 req/min) on login/register
and Emby AuthenticateByName endpoints

Audit-driven port from the original Python MediaStation. Eight major
subsystems that were absent from the Go rewrite are now in place,
each with its own service, handler, frontend page and smoke-test
assertions.
Backend services
- service/crypto.go: AES-256-GCM encrypt/decrypt for at-rest secrets
keyed off the JWT secret. Legacy plaintext rows pass through
unchanged for smooth upgrades. Unit-tested.
- service/api_config.go: third-party provider config (TMDb, Bangumi,
TheTVDB, Fanart, Douban, OpenAI). Seeds defaults on first run.
Encrypts api_key on write, returns masked 'abc1****wxyz' projection.
- service/duplicate.go: sparse-sample MD5 (head + middle + tail, 1MiB
each, plus file-size suffix) duplicate finder. Picks 'best' primary
(matched > size > id) and marks others is_duplicate=true.
- service/filemanager.go: server-side allow-listed file browser used
by the library-path picker. Strict path-traversal protection.
- service/dlna.go: real SSDP M-SEARCH discovery + AVTransport
SetAVTransportURI/Play SOAP cast. 30 s discovery cache.
- service/scheduler.go: 3 recurring background jobs (library_scan
60min, transcode_cleanup 24h, recycle_purge 24h with 30-day
cutoff). Status + run-now endpoints.
- service/cache_cleanup.go: walkAndPrune helper used by scheduler.
- service/storage.go: DB-only disk-usage breakdown by library and by
container format.
- service/emby_compat.go: read-only Emby/Jellyfin shim
(System/Info, Users, Users/x/Views, Items, PlaybackInfo) so Infuse
/ VidHub / Kodi can browse MediaStationGo libraries.
Model updates
- Media: new strm_url (302 redirect target), file_hash, is_duplicate,
duplicate_of fields.
- APIConfig: new table for encrypted provider secrets.
- AutoMigrate registers APIConfig.
Stream layer
- StreamService.ServeFile now redirects 302 to strm_url when set so
WebDAV / Alist / S3 / HTTP direct links work transparently.
Handlers + routes
- Authed: GET /files, GET /storage, GET /dlna/devices, POST /dlna/cast,
PUT/DELETE /media/:id/strm, POST /strm/import,
POST /duplicates/{scan,unmark}.
- Admin: GET/PUT/DELETE /admin/api-configs/:provider,
GET /admin/scheduler, POST /admin/scheduler/:name/run.
- New /emby/* group: System/Info, Users, Users/:userId/Views,
Users/:userId/Items, Items/:id/PlaybackInfo (auth-required).
Frontend pages (lazy-loaded, 7 new chunks)
- DlnaPage: device list + media picker + cast button.
- FileManagerPage: root selector + breadcrumb + sortable listing.
- APIConfigsPage: per-provider card with masked-key editor.
- StoragePage: usage tiles + per-library bars + per-container grid.
- DuplicatesPage: scan form + grouped report with primary highlight.
- SchedulerPage: live job table with run-now button (5s refresh).
- Sidebar reorganised: 自动化 group adds DLNA, 管理 group adds
存储 / 文件浏览 / 重复文件 / 定时任务 / API 配置.
Smoke test additions (all admin-only)
- api-configs seeded with 6 providers
- api-config encrypted in db (sqlite3 enc:v1: prefix check)
- storage breakdown
- file browser lists library root + rejects /etc (path traversal)
- dlna devices endpoint
- scheduler exposes 3 jobs + run library_scan
- emby /System/Info + /Users/{x}/Views
- strm set + stream 302 + strm clear
- duplicate scan
Verified: go build, go vet, go test (incl. new TestCrypto* suite + the
existing TestParseEpisode/TestCleanQuery/TestSrtToVTT/TestStripASSTags/
TestBuildFFmpegArgs); tsc -b && vite build emits 28 route chunks plus
the deferred hls chunk; main bundle 253 KB / 85 KB gzipped; smoke test
PASS=42 / FAIL=0.
