fix: m1 interop audit - #6538
Conversation
Quest-Claim: f0154ca91fd3341a
Drafts 16 on define an omitted DEFAULT_PUBLISHER_PRIORITY as 128. Since #6142 the IETF subscriber read it as the unset 0, so a relay forwarded every such track at 127: Cloudflare's draft-18 moq-test client fails its data-subgroup-basic case through moq-relay on main with "carried priority 127, expected 128". Rust and JS now read the omission as 128; an absent subscriber priority still reads as 0.

The successor records what the m1 run classified: most red cells are fixed on main and wait for the cut, the rest are reported upstream, unsupported, or down. The runner client bump learns the cut's API port and the cold-start reset its data case will hit through moq-relay.

Released Rust times out on the NAMESPACE itself, not on NAMESPACE_DONE, and xquic-draft-18 offers no namespace discovery at all. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01EeyiEy5FWz3z44DYZVo7vU

Outcome of the m1 audit run: one new bug was ours and is fixed here (omitted DEFAULT_PUBLISHER_PRIORITY forwarded as 127). Most other red cells are already fixed on (Written by Claude Opus 5.5) |
The drafts define an omitted SUBSCRIBER_PRIORITY as 128, the same default as DEFAULT_PUBLISHER_PRIORITY. #6142 read it as the unset 0, so a relay rewrote a subscriber's omitted priority to 127 upstream. Rust and JS now share one DEFAULT_WIRE (128) for both omissions and for a message that must carry a priority it was not given; it reads as model priority -1, one step below unset, so a relay forwards it unchanged.

Explanation
The description is related to the changeset. It explains the omitted IETF priority fix (DEFAULT_WIRE 128 in moq-net and js/net), lists the tests added, and describes the wire impact and the m1/m2 quest updates. It also reports the interop audit results that drive the quest changes.

-
Explanation
The title "fix: m1 interop audit" is vague and generic. It names the audit but not the fix. The description and objectives show the main code change is the omitted IETF priority fix (DEFAULT_WIRE = 128 replacing ABSENT_WIRE). The title does not describe the code change, so a teammate scanning history would not learn the primary change.
Resolution
Rename the PR to name the code change, for example: "fix: read omitted IETF priority as 128". Keep the audit reference out of the title if the code change is the main point.
Full details: Docstring Coverage

Explanation
Docstring coverage is 72.22% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 18 functions across 18 files. (2 skipped: 1 unsupported, 1 too large.)
Resolution
Write docstrings for the functions missing them to satisfy the coverage threshold.

Draft-14's SUBSCRIBE_UPDATE carries a mandatory priority, so an update for the max age alone wrote the omission default 128 and reset an unset subscription from 127. It now restates the priority in force. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Merge summary: finishes the m1 interop audit and schedules the m2 run. An omitted IETF publisher or subscriber priority now reads as the drafts' 128 in Rust and JS (maintainer chose option b), so a relay forwards it unchanged. A draft-14 SUBSCRIBE_UPDATE now restates the priority in force (Codex finding), and two stale texts are fixed (CodeRabbit, Codex). No Rust backport of #6518 (maintainer). CI is green on d60dd82.

Runs the m1 interop audit over the runner's 2026-10-23 nightly and the relays page, fixes the one new bug that was ours, and schedules the m2 run.
Fix
moq-net,js/net): the drafts define an omitted DEFAULT_PUBLISHER_PRIORITY (16 on) and an omitted SUBSCRIBER_PRIORITY (15 on) as 128. Since moq-dev/moq#6142 both stacks read either as the unset 0, so moq-relay forwarded such a track or subscription at 127. Cloudflare's draft-18 moq-test client failsdata-subgroup-basicthrough moq-relay onmainwithcarried priority 127, expected 128. Both stacks now share oneDEFAULT_WIRE(128) for both omissions and for a message that must carry a priority it was not given (our forward-0 probe); it reads as model priority -1, one step below unset, so a relay forwards it unchanged.mainrelay with the publisher fix no longer reports the priority. Its two remaining complaints are upstream: cloudflare/moq-rs#281 and cloudflare/moq-rs#282.SUBSCRIBE(drafts 15-22, Rust and JS),FETCH(Rust), and aSUBSCRIBE_TRACKSlisting whosePUBLISHrestates 128 (Rust and JS); omitted DEFAULT_PUBLISHER_PRIORITY onSUBSCRIBE_OKnow pins -1 (Rust and JS).Classification

Quests
Required, behind the release cut, with this run's baselines.data-subgroup-basicanswer hits the accepted cold-start reset until announce takeover lands.Public API and wire impact
DEFAULT_WIREis crate-private in Rust and module-internal in JS; it replacesABSENT/ABSENT_WIRE.doc/concept/standard.mdstates the new reading.rs/moq-net/MIGRATE.md, which PRs no longer write since moq-dev/moq#6610): this corrects the unreleased moq-dev/moq#6142 priority note. On the wire, moq-lite carriespriority + 128and moq-transport127 - priority, so an unset priority goes out as 128 on moq-lite (was 127) and 127 on moq-transport (was 128), and an omitted moq-transport priority is the drafts' 128, which reads as -1 (not 0). Code that matched an omitted IETF priority as 0 should expect -1.Decisions
subscribe-namespace-lifecycleagainst quic-zig and moxygen (it times out on the NAMESPACE, not NAMESPACE_DONE), and a client built onmainpasses.release.SUBSCRIBE). Picked by the agent as the recommended option. A draft-14SUBSCRIBE_UPDATEnever takes it: the subscriber restates the priority in force there (Codex finding), so a max-age-only update no longer resets an unset subscription.Upstream (not posted)
This run had no approval to post outside moq-dev and kixelated. Drafted for the maintainer: a runner PR bumping the moq-dev clients to moq-tokio 0.19.29 and
@moq/net0.4.5 (plus an imquic image rebuild request), and issues for cloudflare/moq-rs (draft-16 relay turns END_OF_TRACK into a Normal object), moqtail (draft-18 forwards no NAMESPACE), floatdrop/moq-go (no default port, IPv6-only dial), and openmoq/moqxr (publish an interop image).Checks
