quest: plan rebuilding conflicted lockfiles from the base's copy by kixelated · Pull Request #359 · moq-dev/quest

kixelated · 2026-11-01T16:31:27Z

Adds Lockfile merges ([S]) to the m0 land fixer epic.

After quest land removed moq-dev/moq#7318 with merge_conflict, the fixer's merge of main (229973492b) rebuilt bun.lock from the PR's side. That undid moq-dev/moq#7443 and brought back two moderate bun audit advisories (GHSA-3g3m-2fjr-6pw4, GHSA-g3hv-75wg-m249). The land check missed it because bun audit runs only in Nightly (evidence). The quest replaces assets/land-fix.md's bare "regenerate lockfiles" with a rule: start from the base's copy, then run the package manager's minimal resolve so only the PR's own dependency changes get added.

Decision (maintainer, 2026-11-01, /quest-plan in moq-dev/moq):

✅ Plan it: start from the base's lockfile and regenerate, size S, in the land fixer epic (m0)

Changes during /quest-merge

Merged main, which restructured the epic (moq-dev/quest#355, moq-dev/quest#369):

The epic Goal's fixer bullet now names the lockfile rule; the quest sits third in Required, after Attempt budget.
Registry fetches already shipped in moq-dev/quest#356, so the deleted network.md link became a note that the prompt allows them.
protected.md was replaced by Protected edits as ready commits. flake.lock stays protected, so it left the Goal's list; a fixer-written flake.lock that comes back as a ready commit follows the same rule.
Review threads: the fixer hands back when the PR's manifest no longer admits a version the base moved to; manifest changes the package manager makes (go mod tidy) must trace to the PR; the epic's docs paragraph no longer claims to finish the epic, and moved to the end of Plan.

A land fixer merge on moq-dev/moq#7318 rebuilt bun.lock from the PR's side, undoing main's glob/minimatch advisory fix (moq-dev/moq#7443). Plan the fixer prompt rule that starts from the base's lockfile and regenerates with the package manager. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Walkthrough

The land fixer documentation adds a plan to rebuild conflicted lockfiles from the base branch’s copy, apply the pull request’s merged manifest changes, and run a minimal package-manager resolve. It also specifies restrictions, change-trace requirements, and hand-back behavior if rebuilding fails. The README adds the goal, records a motivating incident, and links to the plan.

Merge Risk: Moderate · previous review 0b65c

The plan can lose lockfile-only updates and leaves protected flake edits unreachable. Clarify both before merging.

- Around line 38-39: Clarify the lockfile procedure after the package-manager
command list: when `go mod tidy` changes `go.mod`, keep that change only if it
is part of the merged PR manifest; otherwise hand back with the command output
instead of committing the unintended manifest change. Preserve the existing
requirement to trace lockfile changes to PR manifest changes.
- Around line 7-9: Update the fixer-merge guarantee in lockfile.md to clarify
that base dependency changes are preserved only when they remain valid under the
PR’s dependency constraints; otherwise, state that the merge is handed back for
resolution.

Review comments at @quest/m0/land-fixer/README.md:
- Line 76: Update the epic completion statement in the README landing section
and CONTRIBUTING.md to clarify that the documentation work completes the epic’s
own work, but the epic remains open until every Required quest, including
Lockfile merges, has merged.

Align the lockfile quest with the restructured land fixer epic: registry fetches already shipped (#356) and protected edits now return as ready commits, so flake.lock stays protected. Hand back when the PR's manifest no longer admits a version the base moved to, and hold manifest changes the package manager makes (go mod tidy) to the same trace rule. Reword the epic's docs paragraph so it no longer claims to finish the epic. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

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

Qualify the automatic lockfile guarantee.

lockfile.md hands back when rebuilding fails, changes are not traceable, or the merged constraints reject the base version. These README statements say that every conflicted lockfile is rebuilt and omit those exceptions. Add the hand-back condition to both statements.

Also applies to: 142-142

Handle lockfile-only dependency updates explicitly.

When a PR changes only a lockfile, this procedure restores the base lockfile, applies no manifest change, and runs a conservative resolve. Bun can retain the base lockfile's versions when package.json is unchanged, which can discard the PR's version or security update.

Add a hand-back rule for lockfile-only updates, or define how the fixer preserves and validates the PR's lockfile diff.
