# Clear System Broadcast

`DELETE /api/system-broadcast`

Retract the active update warning. system_admin only.

Retracts on BOTH surfaces: drops the banner and takes the announcement off
/avisos. Clearing only the Redis key would leave a withdrawn message
readable by every user of every tenant indefinitely while the UI says it is
gone. (The per-worker startup auto-clear in app/main.py stays cache-only —
it fires 5x per deploy and must not touch the archive.)
