Summary

Plans quest/m0/land-fixer, an m0 epic for what the land fixer cannot fix by itself today. It comes from an audit of the 406 fixer handbacks posted 2026-10-30 to 11-01 on moq-dev/moq, moq.pro, rust2, rind and quest. The epic README holds the full table of causes, counts and owners.

The core rule, from the maintainer: "The fixer is meant to handle conflicts and failures without kicking stuff out of the queue." A conflict or a failing check parks a PR (keeping its auto-merge) while its fixer job runs, and only a handback takes it out of the queue.

New quests:

• attempts.md [S]: only a fix that fails again spends a pick's single attempt. 98 handbacks said only "already used its mechanical fix attempt".
• network.md [S]: the fixer container reaches package registries, so it builds and tests before requeuing. cargo failed offline on the uniffi git dependency in 17 of moq's last 40 fix jobs, and unverified fixes sank batches.
• flaky.md [M]: the gate reruns failing modules once. A flaky test (rerun passes, or the fixer judges it nondeterministic) is disabled by a commit in the next batch, and a follow-up quest goes in the repository's m0 flaky epic.
• protected.md [S]: the fixer edits protected paths when it judges the edit mechanical. This reverses host-land/fixer's 2026-10-30 decision.
• fork-commit.md [S]: when GitHub refuses the App's push to a fork, the handback carries a ready commit (base, tree hash, resolution patch) that a maintainer session applies as is.

Moved under the epic and rewritten to park instead of eject:

• host-land/triage.md becomes land-fixer/triage.md. It now points to attempts.md for the counting rule.
• land-mergeability.md becomes land-fixer/mergeability.md, resized from [XS] to [S].

host-land/fixer's protected-path line now notes that it is superseded.

Found while starting the work: the fixer's offline builds come from assets/land-fix.md's "Never push or contact GitHub", not from the host, which already gives the fixer public egress. network.md now plans a prompt change.

Already fixed, so not planned: fixer crashes (#320, #332), "disappeared" fixers, the repository size cap, AGENTS.md false positives (#325, #328), and "picked again while fixing", which keeps the newer pick.

Decisions

Settled with the maintainer in /quest-plan; ✅ marks the pick. Each quest's Plan records its own prompts.

1. Goal scope: as stated · narrower · ✅ broader, also folding in triage and local mergeability
2. Attempt counting: ✅ only failed fixes count · one per head · N per pick · keep one per pick
3. Dependencies: host prefetch, read-only · ✅ allow registry network · leave it
4. Protected paths, first round: verbatim hunks only · ready commit · keep blocking. The maintainer answered: "Up to the fixer to determine what is mechanical".
5. Protected paths, second round (challenging the earlier decision): the fixer decides and a review is required · ✅ the fixer decides and the fix lands ("Any prompt injections should be caught before enabling auto merge") · workflows stay blocked
6. Refused fork pushes: grant workflows · ✅ hand back a ready commit · leave it manual
7. Flaky tests: ✅ rerun the failed module once · the fixer names the flake · nothing new
8. The maintainer added: "make a rule to immediately disable any flakey tests and create a follow-up to fix/delete them". Who disables: the fixer opens and queues a PR · the fixer opens a PR and a maintainer picks it · ✅ inside the next batch. What counts as flaky: rerun passes only · ✅ rerun passes, or the fixer judges it nondeterministic. Where the follow-up goes: ✅ a flaky epic in m0 · the earliest milestone, ungrouped · m1
9. Milestone: ✅ m0 · m1
10. Added when starting the work: conflicts and failures never eject; the PR is parked for the fixer and leaves the queue only on a handback.

Checks

• quest check passes (80 documents), and so does just check.

Review

• Local quest review (Codex, gpt-6.1-sol, medium effort) against origin/main at head 1388ec9e38dd4e11a596cd6e8c07fa7b799fabc2: round 3, 0 findings. Rounds 1 (06ddb38) and 2 (f1f13da) also had 0 findings.
• CodeRabbit's 9 findings on f1f13da: 8 fixed in 1388ec9. One was declined: the protected-path finding asked to keep an enforced validator, but the maintainer decided explicitly that the fixer decides and the fix lands; that decision is recorded in protected.md.

- Line 92: Update the host-land Goal and plan text to match the contract linked

auto-merge, and reserve queue removal, including removal of quest:merge, for
fixer handback.

Review comments at @quest/m0/land-fixer/attempts.md:
- Around line 28-32: Complete the persisted outcome contract in attempts.md and
the Attempt definition: name the outcome field, specify how records without it

Update handbackRepeated to exclude unchanged and merged outcomes from repeat
counting while preserving the specified legacy-record behavior; ensure a
fixer-modified head that fails checks still triggers handback.

Review comments at @quest/m0/land-fixer/fork-commit.md:
- Around line 25-30: Update the handback format and `quest land apply <pr>` flow
to record and validate both parent SHAs, including the PR head SHA. Before
creating the commit, compare the current PR head with the recorded SHA and abort
on a mismatch; continue applying the patch only when the parents match.
- Around line 25-26: Update the GitHub push explanation in the handback text to
describe the permission boundary: GitHub rejects an App’s push when its token
lacks the workflows repository permission for the targeted repository. Clarify
that the commit can still travel through Git, and avoid claiming that all fork
or upstream pushes are rejected.

Review comments at @quest/m0/land-fixer/network.md:
- Around line 5-8: Clarify the credential boundary in the fixer-container
documentation: state explicitly whether `OPENAI_API_KEY` used for CLIProxyAPI
authentication is permitted, and apply that same rule consistently in both quest
descriptions so the authentication guidance and secret-handling policy agree.
- Around line 25-30: Update the host network contract for the fixer so it allows
crates.io and its index and static hosts, npm, PyPI, the Go proxy, and HTTPS
access to github.com and codeload.github.com; keep api.github.com unreachable.
Ensure the policy no longer says the fixer reaches only CLIProxyAPI.

Review comments at @quest/m0/land-fixer/protected.md:
- Around line 35-40: Keep the protected-content safety gate in validateFix and
ensure it runs before collectJob pushes the fixed head or re-enables auto-merge.
Implement executable path and content validation, keep the fixer prompt aligned
with those checks, and add adversarial tests for prompt injection and task
redirection.

Review comments at @quest/m0/land-fixer/triage.md:
- Around line 62-63: Update the repair-attempt wording in the triage text to
match the outcome-based counting rule in attempts.md, replacing “one attempt,
after it is ejected.” Ensure the wording handles unchanged and base-merge
outcomes consistently with attempts.md.
- Around line 6-12: Update the older decision notes in the quest land fixer plan
that describe ejecting all PRs when attribution is unclear; mark them as
superseded or rewrite them to match the current policy of parking every PR while
keeping the batch queued when the base is green.

Walkthrough

The changes add land-fixer planning documents and update related quest indexes. The documents describe queue handling, attempt counting, flaky-check handling, registry access, protected-path edits, and recovery from refused fork pushes. The changes document policies and proposed work; they do not include implementation changes.

Merge Risk: Low · up to f1f13

This PR only adds planning documents, so nothing changes at runtime. Some documents still contradict each other on queue handling, attempt counting and network access, and the protected-path plan drops a safety check without a stated replacement. Reconcile these documents before implementation starts.

Define the parked transition for a local prepareHead conflict.

mergeBase can return merge_conflict, and prepareHead passes that result through. serveBatch then converts it into failure.ejections; resumeFailure calls eject() and forgetHeads() before starting the fixer. This disables auto-merge and removes the preparation state, which conflicts with the rule that the PR stays queued and parked until handback.

Define the result and queue transition for this branch. State how the fixer receives the parked PR and how later queue passes skip it without ejection cleanup. Keep eject() and forgetHeads() for handback only.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Use flaky consistently.

The document uses flaky elsewhere, but this quoted follow-up says flakey. Correct the wording or mark the preserved quote with [sic].
