Plans moq's CI follow-ups from the 2026-10-31 host-gate work in moq-dev/quest: moving moq.pro and rust2 onto quest land, and the fixer repairs in moq-dev/quest#320, #325, #327 and #328.

Changes

All three join the m0/ci epic right after land.md.

• ci-fail-fast.md [S]: dropped: #7466 implemented it. the land gate's just ci stops every lane at the first failed module.
  • Two batches today failed check gh in 2 seconds and still ran 32-40 minutes.
  • It's an opt-in that the land check sets. sh/dispatch.sh keeps running every lane by default, as it intends.
• nix-cache-5xx.md [S]: a transient nix.moq.dev 5xx becomes a cache miss. One .narinfo 500 failed a seven-PR batch, and Nix's fallback covers only downloads. The fix is preferred in the cache Worker.
• gate-quick.md [XS]: cheap checks run through quest gate --quick. The condition: moq-dev/quest#324 lands and moq bumps quest.

Decisions

Decided 2026-10-31 by the user in /quest-plan: ✅ all three in m0. Each could also have gone to m1 or been dropped.

The quest-side follow-ups are in moq-dev/quest#329.

Review

quest review --base origin/main (Codex), round 1 on head ae90d79: no findings. just check passes.

• Head 4c4eb95 drops ci-fail-fast.md, which ci: let the land gate stop just ci at the first failed module #7466 implemented, and merges main. quest check passes. The review was skipped as trivial (a quest removal).

Automated review by review (OpenAI)

Reviewed commit: ae90d79

No actionable bugs found in these planning changes. The direction is proportionate: make fail-fast specific to landing while preserving local diagnostics, address cache lookup failures at their source, and keep quick admission conditional on the Quest implementation and pin update. Reusing dispatcher process-group cancellation and module metadata avoids a separate orchestration layer.

Verification limits: static review of the plans and relevant dispatcher context only. No tests run; the reported production timings and cache incident were not independently reproduced, and these plans do not implement or validate the proposed behavior.

Reviewed changes

• ci-fail-fast.md [S]: plans an opt-in for the land gate so just ci stops every lane on the first failed module while sh/dispatch.sh keeps its all-lanes default.
• nix-cache-5xx.md [S]: plans turning a transient nix.moq.dev 5xx into a cache miss, preferred at the cache Worker, cross-linked from nix-cache-verify.md.
• gate-quick.md [XS]: plans routing cheap modules through quest gate --quick, gated on quest#324 and the flake pin.
• README.md: adds the three index bullets under ## Required, after land.md.

Each cited reference checks out: quest#324 is open and ships --quick with a 60s bound; quest#320/#325/#327/#328 are merged fixer repairs; quest#329 plans the quest-side follow-ups and cites moq#7250/#7257, with #7250 carrying the "held for an hour" evidence; check flake is a real module (sh/dispatch.sh:332) and the kill -TERM -- "-$pid" / "one unavailable check cannot hide unrelated failures" wording matches sh/dispatch.sh:504 and :524. No duplicate quest exists for any of the three.

Walkthrough

The README adds requirements for handling transient Nix-cache 5xx responses and limiting cheap modules’ admission wait when quest gate --quick is available. Two quest documents describe plans for bounded admission waits and cache lookup error handling.

Merge Risk: Low · up to 4c4eb

The CI plans remain mergeable with owner awareness: the proposed cache response could cause avoidable misses, and the quick gate could admit dependency installation during host pressure.

recorded without preventing the CI lookup. Return an object found in either
bucket; if neither lookup finds it, return 404 only for misses and propagate
storage or permission errors instead of silently treating them as misses.

Do not classify the whole markdown module as quick.

check:markdown first runs bun install --frozen-lockfile and then runs sh/markdown.sh check. quest gate --quick starts after 60 seconds even when memory admission is still unavailable, so a cold dependency install can start under host pressure. Keep dependency installation under normal admission and mark only the actual markdown check as quick. (raw.githubusercontent.com)

Minor · Performance & Scalability · Quick win

Keep the second bucket lookup available after a bucket error.

infra/nix/src/worker.ts checks RELEASE before CI. If the implementation returns 404 when RELEASE.get(key) fails, it skips CI, even when CI contains the object. Catch and record the failure per bucket, then continue to the next bucket. Return 404 only after both lookups miss or fail. Do not silently convert persistent storage or permission failures into cache misses.
