Context
The implementation already contains a source-shaped Apollo fake, native recovery, bounded gateway queues, fair pacing, Verse framing/QUIC, independent client support, lifecycle reporters, and low-cardinality telemetry. Audit defects arise where those existing pieces are bypassed or not connected.
Goals / Non-Goals
Goals:
- Reuse the existing production path for policy, lifecycle, recovery, telemetry, and qualification.
- Delete duplicate qualification simulation.
- Preserve all trust, cleanup, and resource bounds.
Non-Goals:
- Add codecs, provider transports, dependencies, or a generic lifecycle/telemetry framework.
- Claim live Apollo/macOS/firewall interoperability.
- Run the normative qualification before immutable consumer resolution.
Decisions
- Format ANNOUNCE from
ProviderStreamPolicyusing the pinned Moonlight common-c bitrate and codec attributes. H.264 and HEVC with audio enabled are supported; AV1 and audio disabled fail before management/network readiness. - Treat the current exact
client_decodestring as the negotiated decode profile. The default advertises the bounded H.264+HEVC set, and provider work must be a member of it. - Consume existing provider events in the gateway session loop. Termination and disconnect cancel forwarding, then reuse current cleanup/release/reporting machinery and its cleanup-pending result.
- On a full audio FEC map, evict the oldest block according to existing block ordering and increment existing drop telemetry.
- Sample existing process counters at heartbeat time; calculate rate from byte and monotonic-time deltas while leaving configured capacity in registration.
- Build qualification on the existing native/provider fixture and public QUIC client path. Production stage observations replace the standalone codec and arithmetic impairment simulator; short smoke gates freeze the wiring, while normative durations remain deferred.
- Preserve the production fair-pacer schedule across short host-timer overshoots so measured allocation can catch up within the already bounded provider queue instead of accumulating timer granularity as lost capacity.
Risks / Trade-offs
- [Apollo cannot represent disabled audio truthfully] → Reject it rather than silently streaming stereo.
- [Provider event races with media] → Cancel the session first and let bounded cleanup serialize final release/reporting.
- [Counter reset or zero elapsed time] → Emit zero measured rate and establish a new baseline.
- [Corrected qualification is more expensive] → Run only short smoke tests until the immutable candidate is frozen.
- [Pacer catch-up can emit a short burst after timer overshoot] → Clamp schedule debt to five milliseconds in addition to the existing 16-packet provider queue.
Migration Plan
Land focused red/green repairs locally, verify through the temporary Protocol workspace, preserve old artifacts as superseded, and stop at the publication boundary. After a separately authorized immutable Protocol release is pinned, freeze inputs and run the corrected normative qualification once.
