Automated review by review (OpenAI)
Reviewed commit: d0a6a26
The consolidation and moving release-blocking work forward are sensible. Four actionable planning issues remain in the inline comments: HLS clips can start mid-GOP, paced replay can expose the final disabled catalog too early, the in-band codec rule loses the CMAF exception, and peer limits omits its newly required dependency. These can be corrected within the current scope.
Verification: read the full 63-file diff and relevant implementation/tests, checked added repository-relative links against this commit's tree, and spot-checked merged-PR claims. GitHub-only static review; no commands or tests run. Check/Test were still in progress. No cross-repository claims verified.

[P2] Snap the clip start to a decodable sync point
Overlapping segments do not guarantee a GOP boundary. The existing long-GOP test splits one 30-second GOP into three 10-second segments. A clip covering 15–25 seconds would select segments 1–2 and omit the only keyframe in segment 0, leaving the clip undecodable. Require the start to include the preceding usable sync point (or explicitly refuse when unavailable), and add a range test over this existing split-GOP fixture.

[P2] Align mutable catalog state with paced playback
Keeping the catalog at its final live edge can hide earlier recorded media. For example, a recording ending with video enabled: false exposes that final state immediately; watch filters disabled renditions before selecting a track, so it never subscribes to the earlier paced video. Removed tracks have the same problem. Immutable codec identity does not freeze these live fields. Pace the relevant catalog changes or define a replay-specific catalog that keeps historical tracks selectable for their playback interval; test a recording that ends muted or removes a rendition.

[P2] Preserve the CMAF exception for in-band codecs
In-band avc3/hev1 does not always mean no description. The existing avc3 import test retains an avcC record with no parameter sets because CMAF samples still need its NAL length size; the native decoder rejects CMAF without that description. This blanket rule either excludes valid below-ceiling in-band resizing or directs publishers to remove required framing data. Distinguish immutable framing records from in-band parameter sets and preserve the container-specific exception already documented in doc/concept/hang.md.

Reviewed commit: 893ee3f
The focused fixes are sound. All four P2s from my previous review are addressed in the plans: sync-point widening for HLS clips, catalog pacing with media, the CMAF framing-description exception, and the Required session-limits dependency. No new issue found in the 10-file fix delta.
Two planning gaps already reported in the independent follow-up review still apply; I checked their implementation context and am referencing them rather than duplicating inline findings:
- Catalog ceiling migration:
quest/m1/catalog-tracks.md:9–12,44–47fixes ceilings at track creation, butrs/moq-mux/src/catalog/estimate.rs:282–283,342–344raises measured rates during a track, andcatalog/tracks.rs:167–170lets detected dimensions replace hints. Specify declared versus measured values, or explicitly plan the estimator/importer and HLS-consumer migration. Include an import with initially unknown rates whose estimate later rises, so normal measurement does not cause repeated identity changes. - Unpaced VOD track discovery:
quest/m1/archive/replay-catalog.md:12–15,24–26leaves the newest catalog at the live edge. If it removed an earlier rendition, HLS cannot discover that recorded media;rs/moq-hls/src/export/renditions.rs:421–445removes absent renditions. Preserve historical track discovery for VOD, for example with an archive-wide catalog, and test removal before recording end. The m3 pacing fix alone does not satisfy m1's whole-recording goal.
Verification: compared the single forward commit against the previously reviewed head; base unchanged. GitHub-only static inspection of the delta, neighboring plans, implementation, and relevant existing tests. No commands/tests run or cross-repository claims verified.

Reviewed commit: 7dbf784
The original four findings remain addressed. This one-commit, three-file follow-up adds the missing migration scope, historical rendition discovery, and equal-timestamp catalog ordering. Two new P2 planning gaps remain in the proposed fixes: frozen estimates can mislead bitrate selection, and the union can pin HLS segmentation to a finished historical rendition. Both are detailed inline with regression cases.
Overall direction: keep stable decoder identity and historical discovery, while explicitly preserving usable rate information and whole-recording timeline coverage.
Verification: compared against my last review, inspected affected consumers and existing reference-timeline tests, and checked current reviews for duplicates. No rebase in this push; the merge base is unchanged, while current main is three commits ahead. GitHub-only static review; no checkout or tests run, and no cross-repository claims verified. Check was still in progress.

[P2] Preserve a usable bitrate bound for rendition selection
Freezing the first estimate while allowing later excess only in stats can permanently understate an imported rendition. Watch's bitrate filter selects using config.bitrate, with a budget derived from connection capacity at lines 315–326; it does not consult per-rendition traffic stats. A quiet-start estimate of 1 Mb/s followed by sustained 5 Mb/s still wins over a sustainable 0.5 Mb/s rung on a 2 Mb/s connection. HLS likewise advertises the catalog value through bandwidth(). Specify an enforceable bound or separate mutable rate metadata, and migrate watch as well as HLS to the usable value. Test this two-rung quiet-start case and sustainable selection, not just that the catalog stops changing.

[P2] Advance HLS boundaries past a retained historical reference
The union fixes discovery but also keeps a removed rendition eligible as HLS's shared segment reference. reference() keeps the current video while its name and timeline remain, and watch() generates every playlist's segment rows solely from that reference. If video0 ends at 10 seconds and video1 continues to 60, the union retains video0, so the latter's 10–60-second media never gets playlist rows. Following stalls there; finishing the replay ends that truncated window. Include an archive boundary/reference-transition strategy covering the full union without discarding earlier rows. Extend the removal test to remove the reference while another rendition continues, asserting both the recording's first segment and its tail remain listed.

Both P2 planning gaps from my last review are addressed:
quest/m1/catalog-tracks.md:39–50permits monotone rate updates and explicitly tests quiet-start 1→5 Mb/s selection against a sustainable 0.5 Mb/s rung on a 2 Mb/s link. This fits the estimator and watch/HLS consumers without changing decoder identity.quest/m1/archive/replay-catalog.md:21–29requires advancing beyond a finished historical reference while retaining earlier rows, with first-segment and tail assertions. This covers the video0-at-10s/video1-through-60s failure case.
No new actionable finding in this two-file delta. The original four findings remain addressed. Overall direction is sound: retain stable decoder identity, usable rate metadata, and whole-recording coverage. These are fixes to the implementation requirements, not evidence that the runtime behavior has been implemented.
Verification: one forward commit since the last review; no rebase, and the merge base is unchanged. Current main is four commits ahead, with no overlap in these two files. Inspected the affected estimator, watch selection, HLS refresh/reference paths, and relevant existing tests; rechecked current state, head, and reviews before posting. GitHub-only static review; no commands/tests run or cross-repository claims verified. Check is still in progress.

- Around line 47-48: Update the plan’s dimension identity rule around the
importer and `catalog/tracks.rs`: specify either that publication waits until
coded dimensions are known, or how an unknown ceiling preserves same-name
identity when dimensions are later filled in. Ensure the chosen rule remains
consistent with the fixed-ceiling requirement.

Define the identity rule for dimensions known after publication.
The catalog can publish a codec-only rendition before the first keyframe. The importer then fills coded dimensions from the keyframe and updates the catalog. This can change the coded-size ceiling after track publication, which conflicts with the Goal's fixed-ceiling rule.
Update the plan to either delay publication until coded dimensions are known or define how an unknown ceiling preserves the same-name identity contract.

Summary
A second quest-tree audit on 2026-10-08 that checks the concurrent audits and plans (#5058, #5059, #5061, #5055, moq.pro#2165/#2273) and the PRs merged since against each other. Each tree was internally sound (
quest check, links, ranks); the drift was between them. Quest files only.js-startup-hole(fix(hang): deliver the first media group without waiting across gaps #5051),auth/wip-version(feat(net)!: AUTH moves to moq-lite-07-wip #5004 landed on the auth line; the 0x3B renumber stays inquest-flat-lines).catalog-tracksm2 -> m1 (re-planned, below),js-track-takeoverm1 -> m0 (Required bypublish-catalog-restart),auth/refusal-reason->m1/refusal-reason(out of the auth line).m2/hls-ranges(range-addressed playlists in moq-hls, for moq.pro managed HLS).codedWidth/codedHeight/bitrate/framerateare ceilings with in-band resolution changes;closure-countersscoped to a same-epoch rejoin;ffi-runtimeis moq-ffi only.track-tail-interopRequiresserve-budget; m3 moq-uring: use SENDMSG_ZC for large UDP GSO trains #3201/moq-uring: register TX-pool buffers for zero-copy sends #3204 Requirequic-io-boundary;archive-paced-replayandreplay-catalogRequire their blockers;cpp-conangets the C++ release blocker; Draft-20 FETCH ranks above Subscribe ranges.Folded into open PRs: #5061 (pipelining sequenced after
