AZ-657 (frame_ingest): RTSP session lifecycle FSM with bounded
exponential backoff (1 s → 30 s cap), AI-lock plumb through
watch::Sender that stamps every emitted Frame, and SPS/PPS
hard-fail via OpenError::UnsupportedProfile. The actual RTSP wire
client is abstracted behind an RtspTransport trait so AZ-658 can
pin retina/FFmpeg alongside the decoder; the lifecycle FSM itself
is production code today. tokio::select! around every transport
call so a hung open/read cannot wedge graceful shutdown. 10 unit +
5 integration tests cover happy path, bounded reconnect, stream-
drop reopen, hard-fail no-retry, and AI-lock toggle.
AZ-682 (scan_controller): typed ScanState (ZoomedOut / ZoomedIn /
TargetFollow) with a complete pure transition catalogue, every
(state, trigger) → next_state from description.md §1/§4/§5 covered;
spec-disallowed combos return TransitionOutcome.accepted = false
with RejectReason::UnsupportedTransition (loud, not silent). Frame-
rate floor monitor with hysteresis suppresses ZoomedOut → ZoomedIn
while sustained FPS < 10 fps per description.md §5/§6. Rolling
100-sample tick-latency window surfaces p99; health goes yellow
above the 10 ms budget. 18 unit + 5 integration tests cover the
catalogue, fps-floor activate/clear, and tick-latency budget.
Cumulative review (batches 10-12): all OPEN findings carried
forward without regressions. See
_docs/03_implementation/batch_12_cycle1_report.md §6.
Notes: pre-existing dead-code error in autopilot::Runtime::
vlm_provider_name (origin batch 4) blocks workspace -D warnings
clippy. Recorded in _docs/_process_leftovers/ — not in batch 12
scope.
