quest: settle macOS capture modes and plan the Nightly benchmark timeouts - #8490
Records the maintainer's /quest-unblock answers from 2026-11-10 and plans the work behind the Nightly benchmark timeouts.
Changes
quest/m3/capture-list.md, quest/m4/capture-foreground.md: the macOS Waiting items are settled and removed. The foreground Goal says what the permission-free mode misses.
New m0 quests, one per Nightly job that hit its 60-minute timeout on every scheduled run from 2026-11-08 to 11-10. Each job has a different cause:
quest/m0/ci/nightly-rust-test-hour.md: Rust benchmark tests spends its hour on separate per-crate release builds; the benchmarks run for about two minutes.
quest/m0/ci/nightly-relay-session-hour.md: Relay session benchmarks doesn't hang. Its paired sweep has outgrown the hour.
quest/m0/lite07-compression-bench-hang.md: Rust bench targets hangs on the first session_delivery_compression/moq-lite-07-wip cell.
quest/m0/js-subscribe-drop-hang.md: JS benchmarks hangs in js/net/bench/subscribe-drop.ts after printing its header.
quest/m0/ci/hakari-followups.md: its Nightly measurement now waits on the Rust benchmark tests quest, and compares only builds that match the baseline's once that quest regroups them.
Each Nightly quest carries the full scheduled-run series from 2026-11-02 (the JS hang dates from 11-04, not 11-08). The relay session quest cites the failed 11-01 job directly, since quest/m3/audit-ci.md was deleted on main, and no longer treats its 14 minutes as a completed sweep.
quest/m2/promote-cluster-routes.md: the open routes PR it waits on is now moq-dev/moq#8443.
Validation
quest check: 522 documents ok.
quest gate just check and quest gate just ci: pass on Linux after merging origin/main. This PR changes only quest/.
Decisions
macOS window changes (capture-list) and front window (capture-foreground): ✅ both modes, the application picks one at setup (rejected: permission-free re-list only; Accessibility only; app events only). Accessibility mode refuses with Unsupported without the permission and never falls back. Basic mode re-lists only while a watch is held.
Nightly (Rust benchmark tests) timeouts: ✅ split the job and reduce its size (rejected: finish moq-dev/moq#8171 with one run; raise the timeout). Milestone ✅ m0 (rejected: m1). The three other timed-out jobs join m0 under the same answer, since each breaks Nightly the same way.
moq-dev/moq#8433 (interop finish): ✅ keep the run_finishes quarantine lifted (rejected: re-quarantine rust/go), now that the C++ client's FIFO hang is fixed.
Route latency: already decided (windowed min RTT) and implemented in moq-dev/moq#8458, which rewrites quest/m2/route-latency.md, so this PR leaves that quest alone.
Public API: none. Wire: none.

Walkthrough
The changes update quest documents with Nightly timeout evidence and plans, two benchmark hang investigations, a revised cluster-route pull request list, and selected macOS capture modes. The capture documents describe Accessibility and permission-free behavior and remove the prior unresolved choices.
Merge Risk: Minimal · up to f66b3
This PR only updates quest documentation. The earlier wording concerns have been corrected, so no merge-blocking risk remains.

Review comments at @quest/m0/ci/hakari-followups.md:
- Around line 86-87: Update the cache measurement plan in “hakari-followups” so
the before-and-after runs use matching build workloads and job boundaries,
isolating the effect of native media exclusions from the invocation and
matrix-job changes in “nightly-rust-test-hour.”
Review comments at @quest/m0/ci/nightly-relay-session-hour.md:
- Around line 16-17: Update the 14-minute baseline in the nightly relay session
discussion, which cites the m3 CI audit, to identify it as elapsed time from a
job that failed with Evicted; alternatively, cite a completed sweep before
presenting the duration as runtime evidence.
Review comments at @quest/m0/lite07-compression-bench-hang.md:
- Line 5: Update the reproduction instructions to distinguish the Cargo bench
target from the Criterion group: use the `session` target and select its
`session_delivery_compression` group, rather than treating the group name as a
bench target.
Review comments at @quest/m3/capture-list.md:
- Around line 132-133: Update the basic-mode documentation in the window-listing
description to specify that it does not require Accessibility permission, while
clearly stating that displaying window pictures requires Screen Recording
permission. Keep the existing listing behavior and documented rate unchanged.

Reviewed changes
macOS capture modes settled — quest/m3/capture-list.md and quest/m4/capture-foreground.md record the both-modes decision (Accessibility events vs permission-free re-listing) and drop their Waiting items.
Nightly timeout quests — four new m0 quests, one per timed-out Nightly job (Rust benchmark tests, Relay session benchmarks, JS benchmarks, Rust bench targets), plus a dependency note in quest/m0/ci/hakari-followups.md.
Route PR link — quest/m2/promote-cluster-routes.md now waits only on #8443.
I checked the cited job conclusions against the Actions API and the 11-10 job logs: the rust-test build accounting, the relay job still advancing cells at the cancel, and the two hangs all match what the quests say. Two notes inline: the date windows in three of the new quests start later than the actual failure series, and the new quests are not linked from their parent Required lists.

Automated review by review (OpenAI)
Reviewed commit b650697. No additional actionable findings beyond the documentation clarifications already raised in review.
Overall direction: separating the four Nightly failures into distinct investigations is supported by the cited 11-10 logs: ongoing relay benchmark progress, a Rust build still compiling moq-ffi at cancellation, a compression run stopping at its first lite-07 cell, and the JS subscribe-drop header followed by no rows. The macOS plans explicitly distinguish the chosen modes and reject silent permission fallback.
Verification limits: GitHub-only static review of the eight changed plans and cited 11-10 job logs. Earlier-run statistics, macOS API behavior, and proposed fixes were not independently reproduced; no builds or tests run.
quest land watch: the merge queue removed this pull request at b650697 because its merge_group build failed (failed_checks).
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.
codex, gpt-6.1-sol, medium effort land fixer note:
The PR adds a reference to /quest/m3/audit-ci.md, deleted on base by commit 6e3d5bb when the audits were consolidated. The queue log states:
351: ci: check quest failed in 1s
354: quest: quest/m0/ci/nightly-relay-session-hour.md:17: link does not resolve: /quest/m3/audit-ci.md
The PR’s own Check job reports the same error at log line 469. A historical file permalink would preserve the cited 14-minute sample; the replacement cost audit does not contain that sample. No files or branches were changed because the fixer instructions say never to edit quest/. Repository checks were not rerun for this handback.
codex, gpt-6.1-sol, medium effort land fixer: check quest fails on the link added at quest/m0/ci/nightly-relay-session-hour.md:17: "link does not re·solve: /quest/m3/audit-ci.md"; correcting it requires editing quest/, which the prompt prohibits.. Recommendation: Replace the deleted audit link with a permalink to its historical file containing the cited sample, preserving the measurement, then run nix develop --command just ci base.

Important
The relay session quest's new premise — that no scheduled run completed the sweep — is contradicted by the two runs it dates: 11-06 and 11-07 finished the workload in about 25 and 23 minutes and failed only at the paired regression gate. That makes "measure the full sweep first" unnecessary and drops the more useful "find what grew" step.
Reviewed changes
Full failure series recorded — nightly-rust-test-hour.md, js-subscribe-drop-hang.md, and lite07-compression-bench-hang.md now list every scheduled run since 11-02 (11-04 for the JS hang), including runs that failed without timing out.
Relay evidence reattributed — the deleted m3 audit's 14-minute figure is replaced with the 11-01 job and a failure series for 11-01..11-07; one run in that range did complete the sweep (inline).
Compression hang localized — the goal now names moq-net's session bench target and the session_delivery_compression Criterion group rather than treating the group as a target.
Capture permission wording tightened — the basic mode requires no Accessibility permission, and window pictures still require Screen Recording in either mode.
hakari baseline scoped — the mbx comparison now waits on the rust-test quest and only compares builds with matching crates, features, and profile.
I re-checked every cited series against the Actions API: rust-test (cancelled 11-03/05/07/08/09/10, failed at 57m and 59m on 11-04/11-06, last pass 11-02 at 34m), bench targets (cancelled 11-02/05/06/09/10, failed 11-03/04/07/08), and JS (cancelled every run from 11-04, last pass 11-02 at about eight minutes) all match.

✅ No new issues found.
Reviewed changes
Relay sweep evidence corrected — quest/m0/ci/nightly-relay-session-hour.md now records 11-01..11-05 as workload failures after 14-20 minutes and the 11-06/11-07 runs as completed sweeps of about 25 and 23 minutes that failed later at Fail on paired regressions, and its plan step is once again "find what grew" between those sweeps and the 11-08 cancellations.
I re-checked the two cited runs against the Actions API: 11-06 (Run workload 14:52:21→15:17:08, ~24.8m) and 11-07 (13:50:39→14:13:27, ~22.8m) both report Run workload: success and then Fail on paired regressions: failure, so the new baseline and the failure split are accurate. This also resolves the prior review's finding on this paragraph.
