+The server is the only public backend surface. The PyMax worker stays inside the Docker network and is controlled through the API/admin page.
 
 ## Security Rules
 
 - Android pairs to the private server with `QMAX_PAIRING_CODE`.
 - API access uses JWT access tokens and refresh tokens.
-- MAX credentials and sessions live only on the Pi in Docker volumes.
+- MAX session files live only on the Pi in Docker volumes.
 - `.env`, service-account files, keystores and runtime data are ignored by git.
 - Attachments are written as `.part` first and moved into place only after full upload.
 - Android image attachments are downloaded to a local `.part` cache and exposed to the UI only after size validation.
 
 ## Current Verified Status
 
-- MAX Web login is authorized on the Raspberry Pi worker.
-- Chat list, message history, text sending and attachment sending are mapped through `worker/src/server.js`.
+- PyMax login is authorized on the Raspberry Pi worker.
+- Chat list, message history, text sending and attachment sending are mapped through `pymax-worker/src/server.py`.
 - Image, video, file and voice attachments are projected through the API and rendered by the Android client.
 - Firebase initialization and Android push token registration are enabled for `xyz.kusoft.qmax`.
 
 ## Remaining Production Checks
 
-- Keep selector drift monitoring for future MAX Web UI changes.
+- Keep PyMax session-expiration monitoring active.
 - Run an unlocked-device visual pass on the connected phone for every major UI change.
 - Replace debug fallback signing with a real release key in `android/key.properties`.
