A token lasts 30 days and only a browser login yields one — the account is federated, so the server cannot mint it. Replacing it meant editing .env and recreating the container, every month. `schulcloud token set` (a hidden prompt, or piped input) and a /token page both send it to PUT /api/token. The server checks it with Schulcloud first — well-formed, unexpired, still logged in, the same account — then swaps it into the config every request reads, restarts the keepalive and saves it in STATE_DIR, a new volume, with mode 0600. At startup the newer of the saved token and TSC_JWT_COOKIE wins, unless they belong to different accounts. A refused paste changes nothing, and the token is never logged. The keepalive's pings carry a generation, so a 401 for the old token that arrives after a swap cannot stop the new cycle. `schulcloud token`, whoami and the log report the expiry and warn a week ahead. Found on the way: a host that is off for more than two hours loses the session however long the token has left — this machine lost it overnight — which is what the always-on Pi is for. 174 tests. Smoke 72/72 on the local instance, and a real swap verified end to end there. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
