Records the breaks on main and the gaps found while landing the 2026-10-24 quest-spawn PRs, so they get fixed before the cut instead of living in PR bodies.

m0 (CI)

  • ci/loom-build: --cfg loom fails to build on main (tests/loom.rs:621, with_groups removed by refactor(net)!: one with_range cursor setter #6138). Reproduced locally.
  • ci/check-without-userns: just check's flake module fails where unshare is refused and cancels other lanes.

m1

m2

Left out on purpose: the red Nightly (owned by m0/nightly), the moq-rtmp Backoff::validate dead code (the m0/nightly/feature-shapes class, noted on #6703), and the HLS quests already written in open PRs.

Public API: none. Wire: none.

Checks: quest check (555 documents ok), sh/markdown.sh check.

Decisions

  • Linear fill first (maintainer, on moq-dev/moq#6722): fill-linear ranks above fetch-range in the subscribe-ranges epic, and fetch-range.md lists it under Required.
  • Merging main dropped this branch's stale copy of quest/m1/env-unknown.md.

(Written by Claude Opus 5.5)

Twelve quests for breaks on main and gaps found while landing the
2026-10-24 quest-spawn PRs: the loom build, `just check` without user
namespaces, the red TS workflow, OBS dropping groups, a slow moq-cli
test, range-count cost, the superlinear fill path, a possible js/net
close race, relay demand gaps, fMP4 boundary sync, moq-c decode start,
and one moq-ffi build definition. bench-ci gains the malloc-pin question.

Reviewed commit: 551585c

No actionable bugs found in this documentation-only change. The quests make pre-cut follow-ups discoverable, distinguish suspected defects from reproduced failures, and preserve reproduction-first investigation instead of treating proposed fixes as established conclusions. Spot checks confirm the stale Loom call, FFI Data-kind construction and C decoder’s Latest start setting.

Direction: linked, independently scoped follow-ups are appropriate. Keeping skipped checks distinct from passed checks and preserving congestion assertions are useful acceptance constraints.

Verification: static inspection of all changed quest files and selected implementation paths. No quest/Markdown checks, tests, benchmarks or CI reproductions run; reported workflow failures and performance measurements were not independently verified.

Adds quests for reported-drop parity between Rust and JS, the flaky OBS
audio-candidate test, and upstream bug reports (faad, retina,
mr-boxington). The release cut gains the moq-cli/moq-gst MIGRATE entries
and the wrapper moq-ffi floors; the interop and dead-code audits gain the
imquic announce timeout, a dead RecvBandwidth branch, and leftover
`dynamic` names.

Reviewed commit: b014ddd

No new actionable bugs found. The additions preserve the unresolved Rust/JS drop-finality decision rather than silently choosing semantics, and capture the OBS flake, upstream reports, migration entries and wrapper version floors as explicit follow-ups. Linked source PRs support the drop-finality and release-compatibility concerns.

Direction: extending existing audits and the cut checklist avoids competing tracking paths; upstream reporting retains an explicit approval boundary.

Verification: static comparison against 551585c, added planning text and referenced PR context. No quest/Markdown checks, tests or reproductions run; reported upstream failures were not independently reproduced.

…s it

Per #6722's decision that fetch-range waits on a linear fill path.

Reviewed commit: 24a7ee9

No new actionable bugs found. Linear filling is now an explicit prerequisite of FETCH-as-range and first in the parent’s required list. The reciprocal prose link is not a dependency, so no cycle is introduced. This prevents expanding use of the known superlinear path before its performance work lands.

Verification: static comparison against b014ddd, separating incoming main changes from the three-file plan adjustment. No quest validation, tests or benchmarks run.

Maintainer decisions (2026-10-25), recorded in moq-dev/moq#6798:

  • resume-drop-final: a reported drop is not final. A group that arrives later is still served. JS changes to match Rust on both the plain-cursor and resume paths. Please record this in the quest.
  • c/decode-start: the hand-written moq-c ships at this cut with parity for every m1 binding feature, so this stays m1. quest: audit the tree and record the 2026-10-25 decisions #6798 rewrites quest/m1/c/README.md as that parity epic, and the generated C line moves to quest/m2/c/. Add decode-start to the new README's Required when you resolve the conflict.
  • ffi-build-flags / obs-data-decode: unaffected.

Record the 2026-10-25 answers in the quests #6707 and #6790 landed:
datagram size, description-less AAC, catalog parity, MKV/FLV codecs,
partial groups, drop finality, and resume. decode-start stays under the
hand-written m1/c line, and api-audit/requests renames moq-c too.
