Finishes quest/m0/queue-watcher/per-base.md.

Summary

• startDaemon resolves the base once, from --base or the default branch, before taking any lock, and stores it in the options for the daemon's life (a renamed default branch needs a restart). serve and watch both pass a default-branch resolver using a contents: read token; defaultBranch moved to land-serve.ts.
• The checkout lock is now quest-land-<base>.lock in the git common directory, and the default state directory is <owner>-<repo>@<base> (base URI-encoded, so / and @ never collide; no repository name contains @).
• serve and watch still share startDaemon, so on one base they exclude each other; on different bases they run side by side, each with its own private clone, state and --method.
• Audited: the open-PR query filters on baseRefName, the own queue's branches and start-up pruning are under quest-queue/<base>/, and the fixer and landed-tree verification read only the instance's state directory, so no instance touches another's PRs.
• quest land serve/watch --help, the README's landing sections and CONTRIBUTING.md now say one daemon per base.
• Test: two startDaemon calls from one checkout on different bases both start; a second on the same base refuses, including with its own state directory.
• Host side: the host module gains per-entry base/method options and an assertion refusing two enabled entries on one repository and base, in a companion PR in the private host config repository.

Choices made without asking

• No migration of on-disk state (per AGENTS.md): each deployed daemon's default state directory moves to ...@<base> and starts fresh (since falls back to start less SETTLE, handled empty). Deploy while no fixer job runs and no PR left the queue in the last SETTLE.
• The host assertion cannot tell a null base from an explicit default-branch name for one repository; its option description says to name it in neither or both entries.

Follow-ups

None.

Automated review by review (OpenAI)

Reviewed head: d840fe6
Reviewed base: 55070e1

No actionable findings in this diff by static inspection.

I reviewed all nine changed files and traced the surrounding queue, fixer, and landing paths. Resolving the base before acquiring either lock makes the per-base checkout lock and default state directory agree for the daemon's lifetime. Both serve and watch retain the shared same-base exclusion, while their private repositories, progress, fixer jobs, and landing records follow the selected state directory. The open-PR queries filter by base, and the existing fixer paths check for retargeted PRs. The changed helper call sites and added tests are consistent with the new signatures.

Direction: the per-base daemon boundary is coherent; no blocking change is recommended from this review. The startup-lock tests cover the central same-base/different-base distinction.

Limits: GitHub-only static review. I did not run builds, type checks, tests, or live concurrent daemons, and did not validate the separate host configuration. This COMMENT review is not an approval or a claim that runtime validation passed.

Walkthrough

quest land serve and quest land watch now scope daemon state and repository locks by base branch. watch resolves the default branch before startup and retains that base across daemon passes. Tests cover separate state paths for different bases and rejection of another daemon for an already-locked base. Documentation describes per-base operation and updates the watcher planning materials.

Merge Risk: Moderate · up to d840f

Resolve startup retry behavior and account for outstanding fixer jobs before merging. Otherwise, a temporary GitHub outage can stop a daemon at startup, and a deployment can miss completed fixer results. Correct the conflicting landing instructions as well.

Full details: Title check

Explanation

The title "feat(land): one daemon per base branch of a repository" matches the main change. The changeset makes startDaemon resolve the base once, keys the checkout lock and default state directory by base, and lets daemons run per base. The title is specific and concise and follows a conventional-commit style.

Full details: Description check

Explanation

The description is related to the changeset. It names the planning document it finishes, explains how startDaemon resolves the base, and describes the lock and state directory naming. It also covers the README and CONTRIBUTING updates, the tests, the deployment impact, and the companion host-config PR.

Match the README state directory description to the code.

The README says $STATE_DIRECTORY or the XDG state home, in <owner>-<repo>@<base>. The code encodes the base with encodeURIComponent, so / becomes %2F. The XDG path also includes quest-land. Add a note so the README matches the code and --help.

Unverified finding

Align the --state help text with the actual default path.

The default is <owner>-<repo>@<encoded base>. A base such as release/v1 appears as release%2Fv1. The XDG fallback also adds a quest-land path segment. The help text names neither. As per coding guidelines, README examples must stay consistent with the CLI --help output, so add a short note about the encoding to both texts.

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

Resolve an empty or whitespace --base before use.

options.base ||= await defaultBase() treats an empty string as unset. This matches the intent for --base "". The base then goes into defaultState and lockRepository unvalidated. A value from --base is not checked against the repository, so a typo creates a new state directory and lock for a base that does not exist. The daemon fails only later, in the loop. Consider failing at startup, before the state directory is created, when the base branch does not exist.

Drain uncollected fixer jobs before deployment.

A finished job can remain uncollected even when no fixer is running. The new state directory will not read that job, so its result can be missed and its parked PRs can reenter batches. Update the deployment notes to require collection or resolution of all outstanding fixer jobs before the cutover.

Retry transient failures while resolving the startup base

When --base is omitted, an outage that exhausts the GitHub client’s retries can make both serve and watch exit before daemonLoop starts. Previously, the loop retried these lookups.

Retry transient failures at the shared startup resolver with backoff. Keep the resolved base fixed for the daemon’s lifetime.
