- IRC: channel state is kept only for rooms the client itself joined, so
JOIN/PART/KICK/NAMES for other rooms can't grow it; users per channel
are capped at 10 000 and the view keeps at most 200 conversations,
dropping the oldest idle query (SEC-20261012-014, F14).
- Recordings: the list reads the header line and the last 64 KiB for the
duration instead of whole files of up to 250 MiB, falling back to a
full scan only when the final event is longer than the window
(SEC-20261012-020, F9).
- Audit log: keeps the newest 10 000 entries (F17).
