Problem

The docs site is the entry point, and several pages had grown into wire accounting and method catalogs. One was also wrong: it said two publishers of the same name fail over mid-group, which is no longer what moq and moqsink do.

Approach

Kept the behavior a newcomer has to know (discovery, epochs, hidden paths, subscription knobs, formats, capture limits) and left method lists to the drafts and API docs. Added a short encryption overview. Dropped the claim that @moq/e2ee exists. Left the audio-jitter page alone: the implementations are tested against it.

Publisher restarts now match main (#4962, #4969, #4955):

  • moq mints an epoch per run (--epoch pins one), moqsink per run, and the RTMP, SRT, and WHIP ingests per connection.
  • Epochs cross a connection only on moq-lite 07 (opt-in). There a newer epoch takes the name: subscriptions to the old run end with Unroutable and the next subscribe reaches the new run. Routes resume only across an identical epoch; an epochless route keeps its subscriptions until it goes, so viewers of a restarted lite-06 publisher wait for the old session to close.
  • The planned Restart model (quest: plan Restart, Rust untimed default, and three follow-ups #5012) is not described: it hasn't shipped.

Impact

  • No public API or wire change.
  • The moq-lite, standards, hang, CLI, relay, JS, binding, gateway, and setup pages are shorter.
  • Wrong claims fixed along the way: hang's scope, moq export hls serving one broadcast (plus DASH), --cluster-tier (dialed links and admitted LAN peers), the AAC encoder, the moq-room sample, the @moq/auth invocation, a stale IETF drain caveat, the audio default preset (Balanced, 20 ms), audio group size, the watch buffer being cheap for audio only, the relay's random first hop (gone), and archive recordings listing the capped HLS window.
  • Root AGENTS.md points doc edits at the new doc/AGENTS.md (excluded from the VitePress build), drops moq-token rows for crates that no longer exist, and points the rs/moq-stats row at doc/concept/stats.md (maintainer-approved).
  • Merging main folded in its --mtls-peer/--mtls-upstream flags, per-run stats epochs, epoch-pinned requests (Rust and JS), microphone capture stamping (with its AEC and host-timestamp limits), the export ts --delay jitter buffer and SRT latency, moq-transport SETUP/GROUP_ORDER strictness, and per-session limits with their stats peaks, each as a line on the page that owns it. Restart takeover is qualified by clock skew in cli.md and contribution.md.

Decisions

Maintainer feedback, 2026-10-08: keep the direction, align with main, describe only what ships. ✅ maintainer 2026-10-08

  1. How should a newer epoch's effect on existing subscriptions read?
  2. Where do untimed tracks and the other changes main landed under these pages go?
    • ✅ One line on the concept or library page that owns the feature, no per-binding repeats (recommended; matches doc/AGENTS.md)
    • Keep every per-binding note main added
  3. Root AGENTS.md still points rs/moq-stats wire changes at doc/bin/relay/config.md, whose stats section is now a link to /concept/stats.
    • Leave it: editing AGENTS.md needs a maintainer prompt
    • ✅ Repoint the row at doc/concept/stats.md here (maintainer approved)

Alternatives

  • Leave the wire notes on the concept pages. They duplicate the drafts and go stale.
  • Add a page per new crate. The crate list already points at docs.rs.

Follow-ups

  • When Restart (quest: plan Restart, Rust untimed default, and three follow-ups #5012) lands, its quest already lists rtmp, srt, rtc, cluster, and moq-lite docs; cli.md "Publisher runs" and use-case/contribution.md need the same pass.
  • @moq/e2ee is still a quest, not a package.
  • OBS announces without an epoch (/quest/m1/obs-epoch.md).
  • sh/rs/stats-docs.py still requires every connection-stats field on each binding page, which cuts against doc/AGENTS.md.

The concept and library pages had grown into wire and API notes. Cut those back to the behavior a newcomer needs, and describe a moq or moqsink restart as a new publisher epoch.

Walkthrough

The documentation adds writing guidance and excludes AGENTS.md from VitePress source processing. It revises protocol, relay, library, media, and command references, including descriptions of publisher epochs, encryption, framing modes, import behavior, and platform capabilities. Several references replace detailed implementation and API descriptions with shorter summaries.

Priority: ⬇️ Low

Merge Risk: 🔵 Low · up to 7fa99

The documentation is mergeable with a bounded follow-up: move the remaining API field lists out of the library overviews and rely on their API-reference links.

Automated review of 73cc023f (docs only, 18 files, +334/−1391)

The trim reads well, and I checked the new links and anchors: every target exists, and nothing in the repo still links to the removed headings (#redundant-publishers was only used by contribution.md, which this PR updates). Dropping the "redundant publishers" claim is right: on main, two moq processes mint different epochs, so they replace each other instead of failing over. Two of the new restart claims still overstate what main does, though.

Should fix

  1. "Viewers move to the new run" only happens on moq-lite 07, and that's opt-in. cli.md:362-371 ("A restart is a new run: viewers move to it…", "the newer run takes the name") and use-case/contribution.md:25-32 ("A second process publishing the same name is a newer epoch, so viewers move to it") say this with no conditions. But the epoch only travels on moq-lite-07-wip, which rs/moq-net/src/version.rs never offers by default ("only reachable when both peers explicitly opt in"). With default settings, moq --connect negotiates lite-06, the relay gets a route with no epoch, and pick() in model/origin.rs keeps a subscription on the route it first resolved through "until that route goes." So a second process does not take viewers while the first is still up, and a crashed publisher's lingering route holds viewers until it times out. That's the exact case these paragraphs describe. moq-lite.md:87-91 states the version limit correctly; cli.md and contribution.md should say the same thing or link to it. (gstreamer.md:61 already makes the same unconditional claim for moqsink on main.)

  2. RTMP, SRT, and WHIP ingest announce without an epoch. cli.md:362-363 lists "import, … HLS or WebRTC ingest" as minting an epoch, and contribution.md says "moq … mint[s] a fresh epoch per run." That's true for stdin import, capture, transcode, archive replay, HLS, WHEP pull, and import ts --program all (each program mints its own). But these paths all announce Route::default():

    • moq import rtmp: rs/moq-rtmp/src/server.rs:1396 (listen) and dial.rs:499 (connect)
    • moq import srt with a single program: rs/moq-srt/src/ts.rs:78
    • moq import rtc --listen (WHIP): rs/moq-rtc/src/server/whip.rs:125

    So on the page titled "MoQ vs RTMP/SRT", a restarted RTMP or SRT feed is exactly the case that does not take the name. Either name these ingests as exceptions (feat!: replace moq --hop with --epoch and stop stamping unnamed publishers #4969's cli.md text already does: "The RTMP, SRT, and WHIP ingests and import ts --program all announce their own"), or narrow the claim to the paths that mint. The PR body's OBS follow-up is the same gap, but these are moq itself.

Non-blocking

  1. Conflicts with feat!: replace moq --hop with --epoch and stop stamping unnamed publishers #4969 (open). Both PRs rewrite the cli.md "Redundant publishers" section, and feat!: replace moq --hop with --epoch and stop stamping unnamed publishers #4969 deletes the moq-lite.md sentence this PR keeps at line 53-55 ("when it is the first hop, a relay puts a random ID … in front of it"). Once feat!: replace moq --hop with --epoch and stop stamping unnamed publishers #4969 lands, cli.md:370-371 ("The CLI keeps one epoch for the life of the process and does not share it with another process") becomes false, because --epoch shares one. Whichever PR merges second needs to reconcile these.
  2. The draft 19+ update behavior got softer. standard.md:31 puts "the only subscription update that is applied is a priority change" under "Refused, not fatal". On main, any other REQUEST_UPDATE ends the subscription with PUBLISH_DONE(UPDATE_FAILED) (ietf/publisher.rs:792). The session stays up, but the subscription doesn't. The old text said this, and a peer would want to know.
  3. cli.md:82-84 contradicts itself. It says import ts logs "a video or audio PID" that goes quiet, then gives SCTE-35 (neither) as the sparse example. The old text said "each elementary stream", which matches the example.
  4. Window mode gives the wrong reason (lib/rs/moq-json.md:18, lib/js/json.md:17). Per moq-json/src/window/mod.rs, a reader isn't handed a record twice because the group header restates retained records explicitly (offset plus suffix), so a header repeating records the reader already has yields nothing. Trimming being an op is a compression choice. Suggested wording: "A new group restates what it keeps explicitly, so a reader that was keeping up is not handed a record twice."

Everything else I spot-checked holds on main (fe0113ff): moq-lite 01-06 and drafts 14-22 in Rust and JS with lite-07 opt-in, epoch ranking ahead of anonymity and cost (route_order), moqsink minting once per run across reconnects, the second-token and alias refusals, @moq/e2ee not existing, and the moq-audio, moq-video, and gstreamer condensations. CI is still queued.

Verdict: ITERATE. Items 1 and 2 are about the very behavior this PR is correcting.

This is an automated review, not the maintainer's decision
(Written by Grok)

Restart takeover only happens on opt-in moq-lite 07, and the RTMP, SRT,
and WHIP ingests announce without an epoch. Also fixes the draft-19
update wording, the window-mode reason, and the import ts silence line.

doc/AGENTS.md keeps the site an entry point for features, with reference
detail left to API docs and drafts.

Addressed the review in 36e2765:

  1. cli.md, contribution.md, and gstreamer.md now say restart takeover is moq-lite 07 (opt-in), and that older versions keep a subscription on its first route.
  2. cli.md names the RTMP, SRT, and WHIP ingests as announcing without an epoch.
  3. feat!: replace moq --hop with --epoch and stop stamping unnamed publishers #4969 conflict: noted in the PR body; whichever lands second reconciles.
  4. standard.md: "any other update ends that subscription."
  5. import ts: "an elementary stream" again.
  6. Window mode: used the suggested wording on both pages.

Also added doc/AGENTS.md so future doc edits keep the site an entry point for features.

Automated follow-up review of 36e27657 (re-review after the push from 73cc023f; one commit, docs only)

This push fixes all the earlier wording findings, and I rechecked the new text against main (fe0113ff):

  • Fixed, item 1 (lite-07 scope). cli.md "Publisher runs", gstreamer.md:60, and contribution.md now say takeover happens on moq-lite 07 (opt-in), and that older versions stay on the first route until it goes. That matches pick() in rs/moq-net/src/model/origin.rs.
  • Fixed, item 2 (ingests without an epoch). cli.md now names RTMP, SRT, and WHIP as announcing without an epoch.
  • Fixed, items 4, 5, 6. The draft 19+ update line now says a non-priority update ends that subscription. import ts says "elementary stream" again. The window-mode reason now matches moq-json/src/window.
  • doc/AGENTS.md plus srcExclude: ["AGENTS.md"] is fine. The config sets no srcDir, so the pattern resolves against doc/ and keeps the file off the site.

Non-blocking

  1. The new failover sentence in contribution.md:27-29 overstates the no-epoch case. "A publisher can hold several connections and subscriptions move to another when one fails" reads as true without an epoch, and it comes before the epoch sentence. On main, a route without an epoch "is never resumed through another route" (Route::epoch doc, origin.rs:476-479). When its route goes, the subscription ends as Unroutable and the player has to subscribe again. That only finds the second connection's route if one exists, and moq itself only ever has one connection (moq-cli/src/args.rs:65-66). Also, "only pulled where they're needed" isn't really why failover works. Suggested wording: "A broadcast can be announced over several connections, and a viewer that loses one re-subscribes through another. With a publisher epoch (moq-lite 07, opt-in), …". The "simple failover" cell in use-case/index.md has the same gap.
  2. Still open, item 3 (conflict with feat!: replace moq --hop with --epoch and stop stamping unnamed publishers #4969). The direct contradiction is gone because the "does not share it with another process" line was dropped. But this PR renames cli.md's "Redundant publishers" section to "Publisher runs", and feat!: replace moq --hop with --epoch and stop stamping unnamed publishers #4969 (head 7ca9c79a) rewrites that same section around --epoch. Once --epoch lands, "Each run of moq announces its own publisher epoch" needs a "unless --epoch is passed" clause, and feat!: replace moq --hop with --epoch and stop stamping unnamed publishers #4969 still deletes the moq-lite.md first-hop random-ID sentence that this PR keeps. Whichever PR merges second has to reconcile both.

CI is still pending on 36e27657.

Verdict: MERGE once CI is green. Both open items are wording or merge-order issues.

For **`moq-vaapi` specifically**, I couldn’t verify that version **0.1.0** explicitly names or certifies `radeonsi`: the available crate docs describe a VA-API H.264 encoder for Intel and AMD, but list version **0.0.3**, not 0.1.0. ([docs.rs](https://docs.rs/crate/moq-vaapi/latest?utm_source=openai)) The project’s current Cargo manifest references `moq-vaapi = "0.1.0"` but doesn’t establish driver-specific support. ([github.com](https://github.com/moq-dev/moq/blob/main/Cargo.toml?utm_source=openai))

So: **`radeonsi` is the driver to try for AMD; whether `moq-vaapi` 0.1.0 works with your GPU/codec remains unconfirmed.**

The indexed docs confirm version **0.1.0** exists, but the available crate overview and encoder page are for **0.0.3**, not 0.1.0.

Automated follow-up review of ade212c2 (re-review after the push from 36e27657; one commit, docs only, the "second trim pass")

I checked the new text against main (fe0113ff). The fixes this push lists all hold up:

  • moq export hls serves only the one --broadcast, as HLS and DASH (moq-cli/src/hls.rs:90-99). --window defaults to 16 s, and --cors-origin is the right flag name.
  • moq auth serve never sets peer (Policy::decide, moq-auth/src/serve.rs:160-168).
  • moq-audio has no AAC encoder, and an AAC request is refused (encode/backend/mod.rs:14-16, plus the aac_without_a_platform_encoder_is_refused test). None of the changed pages still claims AAC encoding.
  • moq-room: Key::sign takes one argument (moq-auth/src/key.rs:565), and the chat track keeps a 10 s HISTORY.
  • @moq/auth has a single moq-auth bin, so bunx @moq/auth generate/sign resolves, and the flags exist.
  • Removing "IETF media streams are not drained yet" is right. The IETF Driver::drained() now waits on owed SUBSCRIBE/FETCH serves.
  • I spot-checked other claims and they match the code: the /sessions filter and the omitted query/token, --cluster-lan-secret, config precedence and --listen, the 300 ms update hold, the <moq-watch> attributes and status values, import --max-age 30 s, export --max-delay 500 ms, and --linger being ts-only.
  • I checked all 201 root-relative links and anchors on the changed pages, and they resolve. No unchanged page links to an anchor this PR removed.

Non-blocking

  1. --cluster-tier is narrowed one step too far. config.md:189 and stats.md:48 now say --cluster-tier applies "for links this relay dials". But Cluster::lan_peer_grant() (moq-relay/src/cluster.rs:1227-1237) also stamps --cluster-tier on every LAN peer that dials in with a valid mDNS credential. Suggested wording: "for links it dials and LAN peers it admits".
  2. The cluster failover paragraph lost its reason. cluster.md:33-35 says "a flapping 07 link cuts the viewers resolved through the 06 one", but the trim dropped the reason: each time the route with the epoch reappears, it supersedes the route without one. Without that, the sentence reads as a non sequitur. Keep a clause such as "because the route carrying the epoch supersedes the epoch-less one each time it reappears".
  3. Stale row in the root AGENTS.md table. Line 105 still sends rs/moq-stats wire changes to "doc/bin/relay/config.md (stats section)". After this push, that section only links to /concept/stats, so the row should point at doc/concept/stats.md.
  4. Still open from the last review, item 1. This push doesn't touch contribution.md:27-29, so "subscriptions move to another when one fails" still overstates the case without an epoch. An epoch-less route ends its subscription as Unroutable, and the viewer has to re-subscribe.
  5. Still open, item 2 (feat!: replace moq --hop with --epoch and stop stamping unnamed publishers #4969). The overlap has grown. This push rewrites more of cli.md (+100/−277) and the top of cluster.md, and feat!: replace moq --hop with --epoch and stop stamping unnamed publishers #4969 (head 7ca9c79a) edits both files, including deleting the "random first hop" paragraph that this PR keeps at cluster.md:45. Whichever PR lands second has to reconcile them.

CI is pending on ade212c2.

Verdict: MERGE once CI is green. Everything above is a wording fix.

[P2] Keep the cheap-buffer claim explicitly audio-only (doc/lib/js/watch.md:142-144). The rewrite removes the decoded-PCM context and now says the buffer holds encoded frames without qualification. In js/watch/src/video/decoder.ts:355-401, decoded VideoFrames are held while sync.wait resolves and closed afterward; a large video buffer therefore retains decoder surfaces and can exhaust the frame pool. Qualify this as audio behavior and warn about video until the planned decode gate exists (quest/m2/watch-decode-gate.md in #5035).

[P3] Retain the inbound LAN exception when describing --cluster-tier (doc/bin/relay/config.md:187-190; doc/concept/stats.md:47-49). I confirmed the existing discussion's point: Cluster::lan_peer_grant assigns config.tier to admitted LAN peers too (rs/moq-relay/src/cluster.rs:1227-1237). Say dialed links and admitted LAN peers so operators can correctly interpret billing/stat labels.

Direction: the feature-first trim, opt-in epoch explanation and clearer reference links are useful. Correct these surviving behavior claims; the large reduction should not turn implementation limits into unconditional guarantees.

Verification limits: static GitHub review of the docs changes, discussion, and selected underlying code; no VitePress build, exhaustive link/anchor crawl, or executable example validation. No duplicate inline thread added.

Resolve the doc conflicts by keeping the feature-level pages and carrying
over what main changed underneath them: per-connection ingest epochs and
`--epoch` (#4962, #4969), no random first hop for unnamed publishers,
untimed tracks, the bounded HLS window, disabled renditions, the audio
group duration and Balanced default preset, and the Go pointer timestamp.

Also address the open review notes: scope restart takeover to moq-lite 07
and today's Unroutable behavior, keep `--cluster-tier` covering admitted
LAN peers, qualify the watch buffer as cheap for audio only, and say an
over-budget JSON append is refused before anything is written.

Merged main and aligned the restart docs with what ships, in 6c325f1 and 8e46ec8:

  • Ingests mint an epoch per connection (feat(gateways): mint an epoch per ingest connection #4962), moq per run with --epoch to pin (feat!: replace moq --hop with --epoch and stop stamping unnamed publishers #4969), moqsink per run. The "announce without an epoch" claim is gone.
  • Restart takeover is scoped to moq-lite 07 (opt-in) and described as today's code does it (Unroutable, then re-request). The quest: plan Restart, Rust untimed default, and three follow-ups #5012 Restart model is not described, since it hasn't landed.
  • contribution.md no longer implies failover without an epoch (Grok follow-up item 1).
  • --cluster-tier covers dialed links and admitted LAN peers (lan_peer_grant), in config.md and stats.md.
  • The watch buffer is cheap for audio only. Video waits as decoded frames (video/decoder.ts).
  • JSON: an over-budget append is refused "before anything is written", matching the producer docs in both languages (CodeRabbit). The other CodeRabbit items were already fixed or their text is gone (the AAC encode row, the VAAPI paragraph). The clock-skew caveat is on the moq-lite epochs page.
  • Declined for now: repointing the root AGENTS.md rs/moq-stats row at doc/concept/stats.md. Editing AGENTS.md needs a maintainer prompt, so it's listed under Decisions in the description.

just check passes locally, including the VitePress build.

Automated follow-up review of 8e46ec8d (re-review after the push from ade212c2; a merge of main at b0f4a996 that brought in #4962, #4967, #4969, and #4972, plus one audio-grouping commit; docs only)

The merge wasn't mechanical: it rewrote the epoch and hop text to match the newly merged code, so I compared the PR's own diff before and after it and checked the new claims against main (edfa1548). They hold up:

  • RTMP, SRT, and WHIP mint an epoch per connection, and import ts --program all mints one per program. ImportSource::takes_epoch() (rs/moq-cli/src/args.rs:782) is false for RTMP, SRT, the WHIP listener, and ts --program all, and validate() refuses --epoch for exactly those. The gateways mint in moq-rtmp server.rs and dial.rs, moq-srt ts.rs, moq-rtc server/whip.rs, and moq-mux ts/programs.rs. The WHEP pull (rtc --connect) correctly takes the per-run epoch (main.rs:702).
  • moq mints one epoch per run (main.rs:531), and moqsink mints one each time it goes to READY and keeps it across reconnects (moq-gst/src/sink/session.rs:285-287).
  • The random first hop is gone everywhere. No changed page still describes it, which matches feat!: replace moq --hop with --epoch and stop stamping unnamed publishers #4969.
  • Audio grouping (the new commit and the moq-audio/publish text). Options::group_duration defaults to zero, giving one packet per group (moq-audio/src/encode/producer.rs:64, and the group_duration_packs_packets_per_group test). JS groupDuration also defaults to Time.Milli(0) (js/publish/src/audio/encoder.ts:250). Opus now defaults to 20 ms packets, or 10 ms with LowLatency (encoder.rs:135-149), so the corrected wording is right.
  • export archive fails on a new source epoch, which matches fix(archive): refuse a resume under another source epoch #4967.

Earlier findings:

  • Fixed, item 1 (--cluster-tier). config.md:196 and stats.md:49 now say "links it dials and LAN peers it admits".
  • Fixed, item 2 (flapping reason). cluster.md:36-38 and moq-lite.md:89-91 now explain that the route carrying the epoch supersedes the one without it each time it appears.
  • Fixed, item 4 (contribution.md). It now says a route without an epoch keeps its subscription on the first route until that route goes.
  • Fixed, item 5 (feat!: replace moq --hop with --epoch and stop stamping unnamed publishers #4969 overlap). feat!: replace moq --hop with --epoch and stop stamping unnamed publishers #4969 merged, and this merge reconciles cli.md and cluster.md with it.
  • Still open, item 3 (non-blocking). In the root AGENTS.md, line 105 still sends rs/moq-stats wire changes to "doc/bin/relay/config.md (stats section)". That section is now a config sample plus a link to /concept/stats, so the row should point at doc/concept/stats.md.

GitHub reports the PR as mergeable against current main. Main's only later edit to a file this PR touches is a separate CMAF paragraph in hang.md. CI is pending on 8e46ec8d.

Verdict: MERGE once CI is green. The one remaining item is a single table-row fix.

Reviewed commit: 8e46ec8

Both prior OpenAI findings are fixed: doc/lib/js/watch.md:142-145 limits cheap encoded buffering to audio, and doc/bin/relay/config.md:195-196 plus doc/concept/stats.md:48-49 include admitted LAN peers in --cluster-tier.

[P3, existing] The unconditional restart wording still overstates takeover (doc/bin/cli.md:236-239; doc/concept/use-case/contribution.md:29-30). This is CodeRabbit's existing clock-skew finding: #5033 (comment). A replacement takes over only if its epoch sorts later; origin.rs:2336-2340 enforces that comparison. The linked epoch page already explains the clock-skew caveat correctly. Qualifying these claims with “a newer epoch” would make the entry points consistent. No duplicate inline comment added.

Direction: the feature-first reduction and reconciliation with current main's epoch behavior are sound. No additional actionable regression found after separating the main merge from the documentation edits.

Verification limits: GitHub-only static review of the diff, prior discussion, and selected implementation/validator code. The required stats-docs fields remain present; no validator failure was established. No builds, tests, link crawl, or runtime checks run independently. The author reports local just check/VitePress success; head Check CI was queued when inspected.

No new actionable issue in the AGENTS.md-only change since 8e46ec8. The rs/moq-stats sync row now points directly to doc/concept/stats.md, which exists and owns the paths, track names, frame shapes, and encodings. That matches rs/moq-stats/src/lib.rs's wire-format reference; doc/bin/relay/config.md correctly remains the configuration entry point linking there. This is the right direction for the row.

The prior P3 restart/clock-skew wording concern remains unchanged in doc/bin/cli.md:236-239 and doc/concept/use-case/contribution.md:29-30: takeover requires an epoch that sorts later, as rs/moq-net/src/model/origin.rs:2336-2340 confirms. It is already recorded at #5033 (comment); no duplicate inline finding added.

Verification limits: GitHub-only static review of the exact one-row delta, its target and source context, and the prior finding. No fresh full-site review, VitePress build, exhaustive link crawl, or runtime tests. GitHub currently reports this head as conflicting with the base.

Automated follow-up review of e2e556f9 (re-review after the push from 8e46ec8d; one AGENTS.md commit plus two merges of main up to e3896bfb; docs only)

The merges weren't mechanical: they condensed what main added under these pages (#5039, #4904, #5023, #4996, and epoch-pinned requests). I compared the PR's own diff before and after and checked the new lines against main (e3896bfb). They hold up:

Earlier findings:

  • Fixed, item 3. The rs/moq-stats row in the root AGENTS.md now points at doc/concept/stats.md (489098f1). Nothing from the earlier reviews is still open.

New, non-blocking:

  1. auth.md:197-199 drops two qualifiers main had. First, moq auth serve refuses to start with --mtls-upstream but no --mtls-peer (rs/moq-cli/src/auth.rs:440, serve.rs:345). Second, "at its next re-check" only comes on its own with --revalidate. Without it, a live session keeps its old marks until a moq auth revalidate push or a reconnect, so an operator who flips the flag on a server without --revalidate won't see the mesh redial. Something like "--mtls-upstream also marks them upstream and needs --mtls-peer. Changing either flag ends each live mTLS session at its next re-check (the --revalidate cadence or moq auth revalidate), so the mesh redials once" keeps the page short.

CI hasn't reported on e2e556f9 yet: only the skipped Auto-merge and Dependabot runs are listed, and the combined status is pending.

Verdict: MERGE once CI is green. The nit above is a wording fix.

[P3, new] Preserve the capture-time qualifications in doc/lib/rs/moq-audio.md:34-36. The merged summary now promises capture-instant stamping and alignment with video unconditionally. A host timestamp can be unusable (rs/moq-audio/src/capture.rs:754-775), in which case encode/capture.rs:871-889 stamps the read time instead; AEC can also delay the processed samples by up to 10 ms (aec.rs:476-481). Main's incoming paragraph stated both limits. Retain a short usable-host-timestamp condition and the AEC allowance so users diagnosing A/V offset do not read this as an alignment guarantee.

The prior P3 restart/clock-skew concern remains unchanged in doc/bin/cli.md:236-239 and doc/concept/use-case/contribution.md:29-30: takeover requires an epoch that sorts later. It is already recorded at #5033 (comment); no duplicate inline finding added. Earlier audio-buffer, LAN-tier, and stats-doc target corrections remain intact.

Direction: the feature-first trim remains useful. These merges contain real documentation adaptations; the mTLS flags, stats epochs, epoch-pinned requests and io_uring window descriptions otherwise track the incoming implementation.

Verification limits: GitHub-only static comparison against the prior reviewed head and respective bases, with focused implementation checks. No VitePress build, link crawl, executable examples or runtime tests. The head-workflow query returned no runs, and GitHub currently reports a merge conflict.

Automated follow-up review of 23c99eec (re-review after the push from e2e556f9; one wording commit, 28b57688, plus a merge of main at b85587c2 that brought in #4645, #4927, #4936, #4924, and #4941; docs only)

The merge wasn't mechanical: it condensed main's new TS export, SETUP strictness, and Docker text into this PR's pages, so I compared the PR's own diff before and after and checked the new lines against the code at 23c99eec. They hold up:

  • Restart takeover depends on the clock (cli.md:236-238, contribution.md:31-32). Epoch::mint() is Uuid::now_v7() (rs/moq-net/src/epoch.rs:18-19), so epochs order by the minting host's wall clock, and a restart on a host whose clock is behind mints an epoch that sorts older. The qualifier is right.
  • Microphone stamping with echo cancellation (moq-audio.md:34-37). The canceller processes 10 ms frames in the mic callback and hands back the delayed output (rs/moq-audio/src/aec.rs:28-29, 476-480), while the buffer keeps the first sample's capture instant. A host without a usable capture time stamps at read (Samples::captured is None, capture.rs:111-113; encode/capture.rs:123-125). Both qualifiers are accurate.
  • export ts --delay (cli.md:97-101, cli.md:292-297, srt.md:42-44) matches main's feat(moq-mux)!: fixed-delay jitter buffer and per-PID T-STD admission for TS export #4645 text: the output trails the source by twice the delay, a frame that can't arrive in time at the rate fails the export, late frames are dropped with video resuming at the next keyframe, and --delay 0 keeps arrival order and drops nothing. No changed page still mentions export ts --max-age or the old skip threshold, and /bin/cli#export resolves.
  • SETUP and GROUP_ORDER strictness (standard.md:31) and the scratch Docker image note (install.md:61-62) match main.

Earlier findings:

  • Still open (non-blocking), last review's item 1. auth.md:197-199 still drops two qualifiers. --mtls-upstream needs --mtls-peer, and moq auth serve refuses to start without it. "At its next re-check" only comes on its own with --revalidate; otherwise it waits for moq auth revalidate or a reconnect.

New, non-blocking:

  1. cli.md now says "decode time" on two different clocks. The Export section (cli.md:99-101) says each frame goes out "up to --delay ahead of its decode time," and Retention and latency (cli.md:293) says each frame "is muxed that long after its decode time." Both are true, because the first is the output's PCR clock and the second is the source clock, but main said so ("on the output's PCR clock") and the condensed text doesn't. A reader sees the two sentences contradict each other. Adding "on the output's clock" to the first sentence fixes it.

CI on 23c99eec is still pending (Check, Test, OBS, Swift, Windows, macOS, and the rest).

Verdict: MERGE once CI is green. Both items above are wording fixes.

  • doc/bin/cli.md:237-240 and doc/concept/use-case/contribution.md:29-32 qualify restart takeover by clock agreement. The existing clock-skew thread is resolved: #5033 (comment).

No new actionable regression found in this update. After separating the incoming main changes from the documentation adaptations, the TS --delay/late-frame behavior, SRT latency mapping, and SETUP/GROUP_ORDER summary match the selected implementation paths. The Docker note also preserves main's scratch-image constraint. The feature-first direction remains sound, with no public API or wire change in the PR's own diff.

Verification limits: GitHub-only static comparison with e2e556f and current main b85587c, plus focused source and discussion checks. No independent build, tests, exhaustive link crawl, or runtime verification; this is not a fresh full-site audit. Head Check CI was queued when inspected. GitHub now reports the head mergeable. No duplicate inline thread added.

Merge summary for 23c99ee:

  • Merged main twice and resolved conflicts by keeping the condensed pages and adding each new feature as one line on the page that owns it: --mtls-peer/--mtls-upstream (auth, cluster; the old "moq auth serve never grants peer" claim is gone), per-run stats epochs (relay config, stats), epoch-pinned requests (Rust and JS net pages), microphone capture stamping with its AEC and host-timestamp limits (moq-audio), the export ts --delay jitter buffer and SRT --latency (cli, srt), and moq-transport SETUP/GROUP_ORDER strictness (standard). The io_uring flow-control refusal is dropped since main now applies those windows.
  • Review fixes: restart takeover is qualified by clock agreement in cli.md and use-case/contribution.md (CodeRabbit thread); the capture-time line keeps its limits (OpenAI review).
  • Kept the maintainer-approved root AGENTS.md edit, including the rs/moq-stats row now pointing at doc/concept/stats.md; PR body Decision 3 updated to match.
  • Restart wording describes what ships: only an identical epoch resumes, an epochless route keeps its subscriptions until it goes, and a restarted publisher announces under a fresh epoch. The route-level Restart with cache invalidation stays in /quest/m0/broadcast-epoch/restart.md until it lands.
  • just check origin/main passes locally, docs build included.

Reviewed commit: 83366d3

[P2, existing] Require a fresh epoch for an encrypted publisher restart (doc/concept/hang.md:173–175). “Pinning the same epoch reuses them” needs an explicit safety warning: with the same credential and track name, it reuses the AES-GCM key; the new producer starts its sequence at zero (rs/moq-e2ee/src/track.rs:27–33), and the nonce is group/frame (protect.rs:7–15). The reuse guard is only in-memory (generation.rs:20–25, 44–49), so a restart can encrypt different plaintext under the same key/nonce. State that encrypted publisher instances must never reuse an epoch under the same credential, as the linked profile already requires. This independently confirms the existing finding at #5033 (comment); no duplicate inline thread added.

The previous low-limit and run-isolation wording findings remain fixed; the nonce warning is a separate surviving concern. No new actionable regression found in this merge's two doc/lib/js/net.md changes: the no-proxy accept restriction and GOAWAY request-routing summary match the incoming implementation and regression-test assertions. After separating main f31c979, the PR's own changes remain documentation-only. The feature-first direction remains sound.

Verification limits: GitHub-only static comparison with 58068e3, the current base, and selected source/discussion checks. No independent build, tests, exhaustive link crawl or runtime validation; this is not a fresh full-site audit.

Automated follow-up review of a0e33393 (re-review after the push from 58068e30; a merge of main at 83366d39 with no change to the PR's own text, plus one wording commit, a0e33393; docs only)

Earlier findings:

  • Fixed (item 1): hang.md:174-176 now says never to pin a previous run's epoch for an encrypted publisher, because it reuses the keys, restarts the group sequences, and so repeats AES-GCM nonces. That matches the code: names and keys are scoped to credential plus epoch, the never-released claims set in rs/moq-e2ee/src/generation.rs:23-25 exists for exactly this reason and doesn't survive a restart, and moq-lite.md:82-84 already says a restarted encoder's group numbers start over.
  • Fixed (item 2): standard.md:28 keeps "any other Subscribe Options value closes the session." SubscribeOptions::decode (rs/moq-net/src/ietf/subscribe_namespace.rs:115-120) returns InvalidValue for anything other than 0, 1, or 2, and the test at line 577 covers 0x03.

Still open, non-blocking:

  • The replica half of item 1 isn't covered. moq-lite.md:93-95 still says replicas share one epoch by passing the same moq --epoch, and the new hang.md warning only talks about a previous run's epoch. Two encrypted replicas running at the same time under one epoch derive the same keys and, from the same group and frame sequences, the same nonces, so unless they publish byte-identical groups they have the same nonce-reuse problem. A short "the same holds for encrypted replicas" on either page would close it.

CI on a0e33393 is pending (Replay, Windows, macOS, among others). GitHub reports the PR as mergeable.

Verdict: MERGE once CI is green.

Reviewed commit: a0e3339

The previous P2 restart warning is fixed in doc/concept/hang.md:174–176: it now explicitly prohibits reusing a previous encrypted run's epoch and explains nonce reuse. The restored Subscribe Options warning in doc/concept/standard.md:28 also matches the Rust and JS decoders' rejection of values outside 0–2.

[P2, existing] Extend the epoch warning to independently encrypting replicas (doc/concept/hang.md:174–176; doc/concept/moq-lite.md:93–95). The latter still recommends a shared --epoch for replicas, while the new warning only excludes a previous run. With the same credential and track, concurrent producers derive identical keys (generation.rs:112–139), each starts at sequence zero (track.rs:27–33), and protect.rs:7–15 uses group/frame as the nonce. Their differing frames therefore collide even without a restart. State that each independently encrypting instance needs its own epoch; same-epoch replicas may forward the original ciphertext unchanged. This is the profile's rule at drafts/draft-lcurley-moq-e2ee.md:131–132, and independently confirms the existing concern at #5033 (comment). No duplicate inline comment added.

Direction: the feature-first docs remain sound. This is a two-file documentation-only update from 83366d3 against unchanged main f31c979; earlier fixes are untouched.

Verification limits: GitHub-only static diff, source/profile and discussion checks. No independent build, tests, link crawl or runtime validation; not a fresh full-site audit. Head Check CI was queued when inspected.

Automated follow-up review of 0901d78d (re-review after the push from 58068e30; two wording commits, a0e33393 and 0901d78d, on top of a merge of main at 83366d39; docs only)

Earlier findings:

  • Fixed (1, e2ee epoch reuse): hang.md:173-177 now says never to share or reuse an epoch under one credential, for a replica or a later run, because two instances on one epoch derive the same keys from the same group sequences and repeat AES-GCM nonces. That matches rs/moq-e2ee/src/generation.rs (names and keys scoped by credential plus epoch, with the in-memory claims set as the only guard) and protect.rs (nonce from group and frame sequence). moq-lite.md:95 now carves encryption out of "replicas share one by passing the same moq --epoch", and the /concept/hang#encryption anchor resolves to the ## Encryption heading.
  • Fixed (2, Subscribe Options): the standard.md:28 Pull bullet has main's clause back: "any other Subscribe Options value closes the session."

I also checked whether cli.md's --epoch section (lines 245-248) needs the same caveat. It doesn't today: rs/moq-cli has no encryption path, so a moq process can't publish e2ee under a pinned epoch.

No new issues. CI on 0901d78d is still pending (Check, Test, OBS, Replay).

Verdict: MERGE once CI is green.

Reviewed commit: 0901d78

The remaining P2 encrypted-replica warning is fixed: doc/concept/hang.md:174–177 now prohibits sharing an epoch under one credential for either replicas or later runs, and doc/concept/moq-lite.md:93–95 excludes encryption from the shared-epoch advice. This matches the profile's per-instance rule and the implementation's epoch-scoped keys and group/frame nonces. Independently verified the same fix noted at #5033 (comment).

No new actionable issue found in this two-file documentation update from a0e3339; main remains f31c979. Earlier corrections are untouched. The feature-first direction remains sound.

Verification limits: GitHub-only static delta, source/profile and discussion checks. No independent build, tests, exhaustive link crawl or runtime validation; not a fresh full-site audit.

Reviewed commit: 7fa9954

No new actionable regression found in the two-commit, four-file update since ebe5c46.

  • doc/bin/relay/config.md:177–180 now correctly describes capacity as a target that the latest group can exceed. This matches cache::Pool and the latest_group_never_evicted regression-test assertions. It addresses the existing finding: #5033 (comment).
  • doc/bin/relay/cluster.md:150–156 removes the contradictory static-price claim while retaining live repricing. The mTLS-only hub guidance at lines 92–98 also matches certificate grants and upstream route filtering. Existing findings: #5033 (comment) and #5033 (comment).
  • The GStreamer opt-in qualification and OBS encoding-mode clarification are consistent with the linked version guidance and dock implementation.

Direction: these corrections improve the feature-first docs without changing public API or wire behavior. The current base 82c3f2f is an ancestor; the PR's own diff remains documentation/site configuration only.

Verification limits: GitHub-only static delta review, selected implementation and test-source checks, and current discussion/state checks. No independent build, tests, link crawl or runtime validation; not a fresh full-site audit. No duplicate inline threads added.
