From matrix-communication
Use when administering a Synapse / Matrix homeserver — list or snapshot all rooms, rate room health (public, unencrypted, orphaned), render a Graphviz map of the room/space tree, force-join users, promote room admins, harden rooms (add-to-space + restrict + encrypt), deactivate Matrix users (with GDPR erase), find biggest rooms by DB size, audit where a user is admin or member, replay join/leave timelines, or search unencrypted history. Trigger on any '/_synapse/admin', server-wide room operation, Matrix user offboarding, or anything requiring a homeserver-admin token — even without 'admin API' in the prompt. Companion to matrix-communication.

Stdlib-only Python wrappers around the Synapse [Admin API](https://element-hq.github.io/synapse/latest/usage/administration/admin_api/index.html) and the Client-Server API. Reads `~/.config/matrix/config.json` (the same file matrix-communication uses).

homeserver and either admin_token or access_token (server-admin) are required. The other fields are optional. Env fallbacks: MATRIX_USER_ID, MATRIX_SPACE_ID, LANGUAGE=en|de, NO_COLOR.
The token is server-admin. Read references/safety-guide.md before any destructive op.
