Problem

An audit of implicit state machines across Rust, JS, and the bindings found about 140 lifecycles encoded as several flags, Options, atomics, or locks whose combinations mean phases. Eleven of them can reach a combination no phase allows, and some of those are user-visible: moq-boy stays frozen for a new viewer, a connection reports Disconnected before its terminal error, MediaCodec and V4L2 decoders get stuck after a failed drain, watch stall stats are wrong, the screen-share toggle stays on after the picker is dismissed, and a graceful qmux close errors every incoming stream.

Approach

A new m1 epic, Lifecycles are explicit state, has 12 children. The audit found four recurring shapes:

  1. A terminal state stored in two or more places.
  2. "Done" marked before the work that can fail.
  3. One-shot handles stored as Options and taken before validation.
  4. Per-phase data kept outside an enum that already exists.

Each child redesigns one area into explicit enums and unions, and every bug is folded into the redesign of its shape. A first child adds a REVIEW.md check and an AGENTS.md line against new instances. Each child reproduces its bugs before fixing them.

The lite TrackRun start-shortcut bug (pending drops never sent) goes into the existing Delete the old start bookkeeping quest, which already owns that state and waits on moq-dev/moq#7670.

Decisions (maintainer, 2026-11-07):

  • Planning scope: ✅ also plan the findings first proposed to drop (TS import finish ordering, json and audio finish retries, the recoverGroup handle swap, rebind after close). Not chosen: plan only the confirmed bugs, or only the user-visible ones.
  • Placement (superseded by the fold below): ✅ user-visible fixes in m1, internal ones in m3. Not chosen: all in m1, or all in m3.
  • rebind: ✅ crate-private. Not chosen: refuse to rebind after close.
  • Fix approach: ✅ fix the root cause; API changes and redesigns are allowed. Not chosen: guarding the one path each bug takes.
  • Structure: ✅ fold each bug into the redesign of its shape. Not chosen: separate bug quests beside a redesign epic, or widening each bug quest to its own module only.
  • Rule: ✅ add it to both REVIEW.md and AGENTS.md. Not chosen: REVIEW.md only, or no rule change.
  • Milestone: ✅ m1, where a child that breaks a published surface moves to m2. Not chosen: m3 after the cut, or small fixes in m1 with the redesigns in m3.

Impact

Quest files only. No API or wire change.

Alternatives

Small, placed bug-fix quests next to a separate redesign epic. Not chosen, because folding fixes each bug at its root.

Follow-ups

None. The children are the follow-ups.

Review

mechanical fix by quest land watch: merged main at 7dd3c07112ba60bee848b1f0cfdca247f59540b4 with the quest merge driver (head 6eee540)

Head 996ee19a44: review skipped as too trivial to need one (Claude Opus 5.5). It changes one quest index line's wording, from pullfrog's thread.

  • Round 1: Codex, gpt-6.1-sol, medium effort (quest review --base origin/main), head 40e9975, no findings.
  • Head ab8ccfd: review skipped as too trivial; it merges origin/main and rewords quest docs for the three pullfrog threads (bug count, the m2 rule for breaking children, links to merged PRs and a finished quest).
  • Local checks: quest check --base origin/main passed (599 documents).

🤖 Generated with Claude Code

(Written by Claude Opus 5.5)

An audit of implicit state machines found 11 reachable bugs and four
recurring shapes. Plan an m1 epic that redesigns each shape into explicit
enums and unions, folding every bug into its redesign, plus a REVIEW.md and
AGENTS.md rule against new instances. The lite TrackRun start-shortcut bug
joins the existing start-bookkeeping quest.

Walkthrough

The pull request adds an M1 quest overview and plans for explicit lifecycle state across networking, media, handles, and producer or importer completion. It also adds review and agent guidance against implicit lifecycle state. A related M2 plan documents a skipped-group loss case in start bookkeeping. The changes add planning documents; they do not implement the described runtime changes.

Merge Risk: Low · up to 6eee5

The planning documents contain bounded inconsistencies that could misdirect later implementation, but introduce no runtime changes. They are mergeable with owner awareness and follow-up clarification before the affected implementation work.

Full details: Title check

Explanation

The title "quest: lifecycles are explicit state" matches the main change: a new m1 epic with 12 child quests that redesign implicit lifecycle state machines into explicit enums and unions, plus a REVIEW.md/AGENTS.md rule. The title is specific and concise and does not describe anything absent from the changeset.

Full details: Description check

Explanation

The description states the problem (about 140 implicit lifecycles, 11 reachable invalid state combinations, and user-visible bugs), the approach (new m1 epic with 12 child quests, four recurring shapes, a REVIEW.md check and AGENTS.md rule), and the scope (quest files only, no API or wire change). It is directly related to the changeset.

Full details: Docstring Coverage

Explanation

No eligible functions found in the changed files. Skipping docstring coverage check. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 0 functions across 0 files.

Automated review by review (OpenAI)

Reviewed head 40e9975 against base fbd1beb.

No actionable defects found in this planning-only change. The inspected source supports the motivating patterns: moq-boy notifies without the condvar mutex; connection termination writes Disconnected before status polling observes channel closure; failed MediaCodec/V4L2 drains bypass recovery; FFI video follow-up registration happens after releasing the producer lock; and screen-picker rejection leaves the room without the live-to-stopped edge its toggle requires.

Direction: centralizing each lifecycle's transitions and ownership is stronger than adding guards to individual failing paths. The reproduction-first requirement, explicit treatment of unconfirmed cases, Rust/JS coordination, hot-path benchmarks and separate handling of published API breaks are appropriate. Preserve existing semantic distinctions during implementation: clean session closure closes incoming stream-accept queues and datagrams cleanly, while unfinished individual streams must still report truncation. Likewise, the start-state follow-up should settle pending drops through the disposition model left by its Drop set prerequisite, without creating a second owner of served/drop accounting.

Verification limits: GitHub-only static review of all 15 changed planning documents and selected implementation paths, including pause, connection status, codec drain/keyframe, FFI video, audio stall, screen capture, QMux teardown, JSON finish and lite start resolution. This was not an exhaustive reproduction of the reported 11 bugs or audit of all roughly 140 instances. No tests, hardware experiments, quest validation, benchmarks or builds were run. Rechecked the open/non-draft state, full head/base and published reviews immediately before posting. COMMENT only, not approval of future implementations.

Important

One structural question before this lands: the plan keeps the epic in m1 while two children explicitly anticipate breaking changes and move to m2, which quest/README.md forbids ("An epic joins the milestone its outcome needs, children included"). The rest is minor.

Reviewed changes

  • New m1 epic — quest/m1/explicit-state/README.md records the 2026-11-07 audit's four implicit-state shapes, the maintainer decisions (root-cause redesigns, fold each bug into its redesign, m1 placement, a rule in both REVIEW.md and AGENTS.md, rebind crate-private), and the 12 required children.
  • Twelve child quests — each names the lifecycle, the bugs to reproduce, the recommended explicit shape, the instances to sweep, and known conflicts. I spot-checked the claims against the source: the moq-boy condvar notify, the trailing Disconnected, the MediaCodec/V4L2 drain holes, the FFI follow race, the screen-picker dismissal, the qmux #closeReason ordering, the TS/JSON finish ordering, the recoverGroup reset, and the PresentState/Join.State/CompletionState pattern references all match the tree.
  • m1 roadmap entry — adds the epic to quest/m1/README.md.
  • m2 start-bookkeeping — records the lite TrackRun "start past everything" pending-drops bug and the recommended Start enum, with the reproduction-first note.

Automated review by review (OpenAI)

Reviewed head ab8ccfd against base 564f53a, comparing with 40e9975 and excluding merged-main changes.

No new actionable findings. The planning update explicitly detaches a child into its own m2 quest if its chosen design breaks a published API, rather than leaving an m2 dependency inside the m1 epic. The finish(self) note now follows that rule. The other edits clarify that eleven counts lifecycles, not individual bugs, and remove stale overlap links after merges.

Direction remains explicit lifecycle ownership with reproduce-first fixes; the milestone split should be applied when each breaking design is selected. Verification limits: GitHub-only static comparison of all 15 PR patches and inspection of the four changed planning documents; no code changes, tests, benchmarks or quest validation run. Rechecked open/non-draft state, full head/base and published reviews immediately before posting. COMMENT only, not approval.

ℹ️ No critical issues — one leftover wording inconsistency inline.

Reviewed changes

  • Reworded the epic goal so the audit's count refers to 11 invalid-state lifecycles rather than 11 bugs.
  • Changed the milestone rule so a child that breaks a published surface leaves the epic and becomes its own m2 quest, and aligned finish-final.md with it.
  • Dropped stale conflict notes for the now-merged #8142 and #8013, and removed the finished video-vaapi link.

✅ No new issues found.

Reviewed changes

  • Reworded the quest/m1/README.md roadmap line for the explicit-state epic to "fixing the bugs in the 11 lifecycles it redesigns", closing the last half of the earlier count correction. The epic goal in quest/m1/explicit-state/README.md already phrased it this way, and no other "11 reachable bugs" phrasing remains in quest/.

quest land watch: the merge queue removed this pull request at 996ee19 because it conflicts with main (merge_conflict).

The land fixer works on it in the background, and the watcher re-enqueues it at the back of the queue once it is fixed or judged flaky, or hands it back here with what it needs.

ℹ️ No critical issues — the merge left two conflict notes pointing at PRs that have now landed.

Reviewed changes

  • Merged main at 7dd3c07 into the branch, re-anchoring the epic's quest/m1/README.md roadmap entry after the new dispatch-cancel line; the PR's own quest content is unchanged.
  • Verified the newly merged base does not invalidate the plan: the qmux graceful-close bug, the moq-boy notify race, and the lite TrackRun start-shortcut pending-drops bug all still reproduce as the children describe.

#8115 merged into main at 2026-11-07T16:31Z and is part of this branch's new base, so there is no rs/moq-boy/src/main.rs conflict left to expect. qmux-close.md:39-41 has the same problem for #8136 (merged 16:44Z); only #8088 there is still open.

Inline comments:
Review comments at @quest/m1/explicit-state/ffi-state.md:
- Around line 54-55: Update the moq-c route ID allocation and lookup used by
moq_route_broadcast so an ID from a closed route can never identify a later
route, even after the global counter wraps. Use generation-tagged IDs or another
mechanism that guarantees stale IDs remain invalid; clearing route entries on
close alone is insufficient.
- Around line 9-11: Clarify the one-shot request contract around
MoqTrackRequests so terminal failures resolve waiting peers with the failure,
while retryable failures leave the request pending; ensure an accepted request
cannot be consumed while peers remain waiting with no way to retry or learn why
it failed.

Review comments at @quest/m1/explicit-state/publish-capture.md:
- Around line 46-48: Update the enablement derivation for both moq-watch and
moq-publish to include the writable connection.enabled state, alongside
connection status and attribute validity. Preserve a user-set false value so the
gate cannot resume playback or capture while disabled.

Review comments at @quest/m1/explicit-state/rule.md:
- Line 26: Clarify the rule’s treatment of `CompletionState` in the example:
state explicitly whether storing the state in a single `AtomicU8` with `get()`
returning an enum satisfies the rule, or whether the example demonstrates only
the terminal transition. Keep the clarification scoped to this representation
and its relationship to the rule.
- Around line 10-11: Update the terminal-transition rule to require that if a
finish fails after completing one track, it records the error and rejects
further input. Preserve the existing terminal behavior for finishes that
succeed.

Review comments at @quest/m1/explicit-state/track-end.md:
- Around line 25-26: Update the track-end guidance to require the same closed
handle to remain stable whether recovery is attached before or after an error is
latched. Do not allow recovery to replace the handle, even when non-final errors
are exposed.

Review comments at @quest/m1/explicit-state/video-drain.md:
- Around line 41-44: The recovery gate can clear before a keyframe decodes
successfully, allowing a later keyframe to release leading pictures prematurely.
Extend the plan for Reader to preserve recover until keyframe decoding succeeds,
keep leading_floor intact across failed recovery attempts, and test the sequence
of a failed recovery keyframe followed by another keyframe and leading pictures.

Review comments at @quest/m2/subscribe-ranges/start-bookkeeping.md:
- Around line 58-59: Revise the Start-state recommendation so Resolved contains
only the start value, not served-group bookkeeping. Describe the transition
using the per-cursor disposition record introduced by Drop set, and avoid
suggesting a separate served-groups record.

Require terminal failures to resolve waiting peers.

If a handler retains MoqTrackRequests and audio initialization fails after acceptance, a FETCH can remain waiting. The handler cannot retry the consumed request. Require terminal failures to resolve waiting peers, or leave the request pending for retry.

the request pending; ensure an accepted request cannot be consumed while peers
remain waiting with no way to retry or learn why it failed.

Require stale route IDs to remain invalid after reuse.

Clearing route entries on close does not prevent the counter from assigning the same ID to a later route. After wrap, moq_route_broadcast can return that route’s broadcast for the stale ID.

Suggested fix

-  broadcast. Use generation-tagged ids or clear ids on close.
+  broadcast. Prevent stale route ids from naming new routes, including after
+  the counter wraps.
Committable suggestion

IMPORTANT
Review the replacement and indentation, then test before committing.

Preserve the writable disable control when deriving enablement.

Both elements expose connection.enabled, which aliases #enabled. A page can set it to false while the element is connected and valid. Deriving enablement only from connection and attribute validity would ignore that setting and could resume playback or capture. Keep user-requested enablement as an input to the gate.

Include the consumer recovery gate in the plan.

If a recovery keyframe fails, Reader clears recover before decoding succeeds. A later keyframe then clears leading_floor, so leading pictures can be delivered. Extend the plan to preserve recovery until decoding succeeds and test this sequence.

The recovery gate can clear before a keyframe decodes successfully, allowing a
later keyframe to release leading pictures prematurely. Extend the plan for
Reader to preserve recover until keyframe decoding succeeds, keep leading_floor
intact across failed recovery attempts, and test the sequence of a failed
recovery keyframe followed by another keyframe and leading pictures.

Recommended: `enum Start { Legacy, Unresolved { skipped, first },
Resolved { start, served } }`, with `skipped` moved out at the transition.

Keep served-group bookkeeping out of the start state.

Drop set replaces TrackRun::served with a per-cursor disposition record. Recommending it in Resolved can lead implementers to recreate a separate served-groups record. Describe the transition using the disposition record instead.

58 - 59:
Revise the Start-state recommendation so Resolved contains only the start value,
not served-group bookkeeping. Describe the transition using the per-cursor
disposition record introduced by Drop set, and avoid suggesting a separate
served-groups record.
