Lifecycle (internal/app + main.go): - App.OnShutdown hooks run after the HTTP server drains, in registration order: Worker.Shutdown (background jobs now drain instead of dying on SIGTERM), DeviceAuthMiddleware.Stop (releases the rate-limiter ticker), Handler.CloseScanner (fsnotify watcher and scan log files) Security headers: - SecurityHeadersMiddleware (survivor of middleware/security.go, renamed security_headers.go) is now on the echo stack: nosniff, frame-deny, HSTS, CSP (unsafe-inline required by the sanctioned theme flash guard + Alpine), referrer and permissions policy Scanner settings cache: - settings saves (UpdateScanSettings + ApplySetting for the three scan keys) now invalidate MediaScanner's 30s settings cache via SystemSettingsHandler.SetScanSettingsChanged, so changes apply on the next poll instead of after the TTL - MediaScanner.Close closes the scan logger, fixing a file-descriptor leak on every per-item rescan (fresh scanners never closed logs) Client fix: - custom-section-builder's add/remove-selection buttons used inline onclick attributes referencing module-scoped functions, which are not global in a bundled ES module: the buttons threw ReferenceError. Functions restored and exposed on window via declare global Also fixes a pre-existing vet error (saveCoverImage copied echo.Context by value, mutex included) and drops the per-key SettingsCache.InvalidateKey variant left callerless by the full-flush invalidation wiring.
