/api/health needs X-Secret-Key but stays outside the rate limit. Only the admin key gets load_errors from /api/services, default error details no longer name the exception class, and a prepare signal replaces aiohttp's Server banner on every response while the CDM routes keep their own.
Session update events carry the new action as action_entry instead of the full log; access lines stay out of the log ring unless --debug. Job events build and redact their dict once, the progress interval matches the 0.5 s poll, and dashboard stats are serialized once.
POST/DELETE /api/dashboard/drain refuses new sessions and jobs (SERVER_DRAINING, 409) and warns open sessions. A CDN can replace a 5xx body, so server errors are now 422, retryable ones and the tunnel check 424, and a new middleware turns any 5xx into 422.
BREAKING CHANGE: INTERNAL_ERROR, DOWNLOAD_ERROR, WORKER_ERROR and the fallback return 422 instead of 500; NETWORK_ERROR and SERVICE_UNAVAILABLE return 424 instead of 503; /api/tunnel/check failures return 424 instead of 502.
Every structured error carries a short ref, appended to its message and logged with the request; /api/dashboard/status gains per-service error counts. Gzip now compresses in place.
/api/dashboard/services and the /status count now use serve.services, else the union of serve.users services lists; ?all=1 lists every installed service.
A session above the cap licenses with the client's own device, and a track above it in an uncapped -q run is handed back to the client. Also names the fallback in the ccextractor crash warning.
Regions in GEOBLOCK refuse the service and everything else is allowed. A hit stops the run with a region error instead of auto-proxying; the check also covers proxy exits and the remote-dl client region.
The licence response lists KIDs a server vault supplied, the client proves them with the decode check, and a bad pair goes to the new session keys/bad route so the server flags its own row. Client vault keys go first over --remote, and the dashboard health warns when no SQLite vault can store flags.
serve.server_accounts lends region-tagged server credentials to remote sessions (round-robin per region, per-key opt-in, per-account cache). Remote sessions no longer fall back to the server's local credentials when the client sends none.
