`cache.keys()` runs Redis `KEYS`, a full-keyspace scan on Redis's single thread that blocks everything else, including session reads in the same cache. Its cost scales with total keys, not matches, and some managed providers disable `KEYS` entirely. The trusted-lobby feature made this urgent: the waiting-list endpoint scanned on every poll, and its polling audience grows from a few admins to potentially every authenticated participant. Switch to cursor-based `SCAN` via two `core.utils` helpers, deleting in bounded batches so cleanup of a large room cannot block either. A single seam also lets us forbid raw `cache.keys()` going forward. `SCAN` still iterates the keyspace incrementally on the polled path. If monitoring flags it, the follow-up is a per-room set index — out of scope here since it changes the lobby storage model.
