Construct the SettingsRegistry at boot, load it, and thread it through
every consumer so the configurable values take effect and stay cached.
cmd/server/main.go:
- Build the registry from the Queries handle and Load() it right after
schema init; a load failure logs and continues (getters fall back to
compiled defaults, so startup is never blocked).
- Wire the registry into the package-level password validator
(SetDefaultPasswordSettings) and call SetSettings on every handler/
service that reads tunables: AuthHandler, DeviceAuthMiddleware,
OPDSHandler, SidecarHandler, SystemSettingsHandler,
AnnotationService, ConversionService.
- Source the restart-time values from the registry: login lockout
(max attempts + duration) feeds NewLoginAttemptTracker, and the new
NewSyncQueueProcessorWithConfig / NewWorkerWithConfig take the sync
queue and worker pool configs.
router.go:
- Config gains a Settings *database.SettingsRegistry field.
- The global auth rate limiter now reads RequestsPerMinute from
registry.AuthRateLimit() (env stays as the enabled/disabled switch
and as the fallback if the registry is unset).
admin_library.go:
- The HTMX scan-settings save endpoint reloads the registry after
writing so the change is visible without a page reload.
- Add PUT /admin/settings/tunable: a small HTMX endpoint that calls
SystemSettingsHandler.ApplySetting and returns a colored status
snippet ("Saved" or "Saved — restart required") for the admin UI's
per-row forms.
