A 6-agent adversarial audit of the client (11 confirmed of 39 findings, the rest
filtered) drove these:
- fix: SessionAudio ring buffer — guard a write larger than the ring (would push
readIdx past writeIdx and corrupt the buffer; never happens, but guard not corrupt).
- fix: CADisplayLink retain cycle (stage-2 presenter) — a weak-target DisplayLinkProxy
so the view can deallocate (the link retains its target); stage-2 teardown added to
both StreamView/StreamViewController deinits as a safety net.
- fix: GamepadFeedback deinit { flag.stop() } — the drain thread holds the connection
strongly and self weakly, so an abrupt teardown without stop() would leak it.
- refactor: centralize the 12 UserDefaults/@AppStorage key literals (scattered across
8 files) into one DefaultsKey enum — a typo silently splits a setting's reader from
its writer.
- docs: RumbleRenderer @unchecked Sendable invariant; the HID digit-row table; the
stage-2 layer compositing.
