Prepares moq-dev/moq's move onto the land daemon. moq's check, just ci "$BASE", chooses its suites by diffing against the base.

Changes

• Sandbox contract: <sandbox> <checkout> <base-sha>, with QUEST_LAND_BASE set. The check's standalone clone is fetched at depth links + 1, so it contains the base and git diff <base> and git merge-base work. There's still no remote and no alternates. quest's own wrapper ignores $2.
• Fixer import:
  • fetch.fsckObjects=true;
  • pack indexes are rebuilt with git index-pack rather than trusting the fixer's. That's not --strict, because one pack may refer to another not yet indexed; fsck already checks every object and link on import.
• Attribution: the fix is credited by the recorded agent in its ## Review line only. The author's (written by …) lines stay as written.

Checks

just check and just test pass (705 CLI and 426 Worker tests).

Review

• Codex wrote the base contract and the import hardening.
• Claude Opus 5.5 reviewed them in a sub-agent and found two issues:
  • strict re-indexing depended on pack order and would have handed back valid fixes;
  • the attribution cleanup removed the author's own lines.
• I fixed both.
• quest review --base origin/main (Codex gpt-6.1-sol, medium), round 1 on head 0175469: no findings.

Walkthrough

The sandbox now receives a standalone shallow checkout that includes the tested tip and the commit chain through the planned base. The launch passes the base SHA as an argument and in QUEST_LAND_BASE, with only PATH and LANG in the environment. Fixer collection rebuilds pack indexes and enables fetched-object checks. Fixer comments and PR review lines use the recorded agent and model attribution. Tests cover sandbox history and inputs, pack handling, and attribution.

Merge Risk: Low · up to 01754

The documented pack-validation command overstates the check performed. Correct it before relying on the documentation.

Full details: Docstring Coverage

Explanation

Docstring coverage is 60.00% which is insufficient. The required threshold is 80.00%. 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 5 functions across 5 files. (1 skipped: 1 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

1017-1032: Trivial · Functional Correctness · Quick win

Assert every selected link path in the sandbox diff.

For three queued PRs, the fixture creates file-1.txt and file-2.txt, but the current assertion checks only file-1.txt. A regression that omits file-2.txt can still pass. Check the complete changed-path set. This validates paths only, not file contents.

Suggested fix

 		const links = 1 + Math.floor(Math.log2(count));
+		const expectedFiles = Array.from({ length: links }, (_, index) => `file-${index + 1}.txt`).join(" ");
 		const options = sandbox(
@@
-				'git diff --quiet "$2"..HEAD -- file-1.txt; code=$?; test "$code" = 1',
+				`test "$(git diff --name-only "$2"..HEAD | tr '\n' ' ')" = '${expectedFiles} '`,

Review comment at @test/land.test.ts around lines 1017 - 1032:
Update the sandbox assertion in the `test.each` case to compare the complete
changed-path set between the base and `HEAD` against the files for all selected
links, using `links` to determine the expected paths. Replace the
`file-1.txt`-only check so the test validates paths without asserting file
contents.
