A new service-identity domain registers the installation with places.liketrek.com on its first Places request, in the background and behind a light scrypt proof of work, keeps the key encrypted in app_settings, renews it from day 60 through a daily job, drops it after three 401s in a row with up to six hours of jitter, and freezes it on a revocation until an admin starts over. TREK_SERVICES_KEY wins and turns registration off; TREK_SERVICES=off sends no key; a mirror set with TREK_PLACES_URL never registers and never sees the key, which goes only to the hosts in TREK_SERVICES_HOSTS over https.
The Places client takes its headers from the identity port, sends a TREK/<version> User-Agent and keeps the instance token. A 401 or 403 does not open its breaker. GET /api/admin/service-identity reports the state, tier and today's allowance, asking the issuer at most every 20 seconds; POST .../regenerate starts a new identity.
Prettier on every new or moved file that was not formatted, so lint:format
holds them; the files taken off the format baseline are the ones that moved
or were formatted on the way.
app-settings.registry.ts lists every app_settings key the server reads by name with its shape, default, environment override and flags. The admin form's keys, its masked and encrypted handling and the public config's reads derive from it, isOidcConfigured() replaces the three issuer/client-id checks in AuthService, and OidcService resolves its values through the same rule while still requiring the client secret. Every literal getValue() read goes through readAppSetting()/resolveAppSetting(), and ESLint refuses a new one.
