Finishes quest/m0/epic-branches/branch.md: a quest inside an epic now opens its PR against the epic's branch, so the epic can land on main as one PR.

Summary

• quest start on a quest inside an epic (quest/<milestone>/<epic>/...) builds its claim on the epic's branch, quest/<milestone>/<epic>/README, and opens its draft PR into that branch. The first claim in an epic creates the branch from main with an empty chore(quest): open epic ... commit and opens the epic's draft PR into main. Its body hands it back with one ## Waiting item until the epic's quests have merged. An epic branch whose tip a merged PR landed, or that holds nothing beyond main (GitHub opens no PR from it), is replaced with a lease. A branch without an open PR gets one. When two claims race to create the branch, the one that loses builds on the winner's branch, and GitHub's 422 on a duplicate PR is accepted. A fork cannot push the upstream's branch, so it refuses until the branch exists. A quest directly under a milestone, and an epic's own README, still target main.
• Readiness now reads each quest from the tree its PR builds on. For an epic with a branch, that tree is the branch as it will be once main is next merged into it (mergeSources in src/core/epic.ts). Each quest file comes from whichever side changed it. A file deleted on either side stays deleted, and when both sides edited a file the epic's version wins. List entries that link to a dropped quest are removed, as quest rm would remove them. The effects:
  • A quest finished on its epic's branch is not offered again, and its siblings are no longer blocked on it.
  • A quest finished on main unblocks epic quests before the branch syncs.
  • A quest outside the epic that requires an epic quest waits until the epic lands.
  • An epic's README is read from its branch, so once its quests are done there, quest start reports it as held by the epic's PR.
• quest unblocked uses this reading in all three forms: plain (the checkout plus the remote's epic branches as last fetched), --unclaimed (the upstream default branch and epic branches) and <path>. For a quest finished on its epic's branch, <path> reports exactly that.
• quest start --release accepts a claim built on the epic's branch, and leaves the epic's branch and PR in place.
• quest review keeps origin's default branch as its default base. A PR into an epic's branch is reviewed with --base <remote>/<base>, as the skills already pass it, using the base quest status now prints. An epic-aware default was tried and dropped in review: it missed forks (whose origin lacks the upstream's epic branch) and quest branches tracking main.
• quest status prints the PR's base (JSON base). quest wait already read the PR's own base. quest check --base takes the base it is given, which the skills already pass as the PR's <base>.
• The guide's Model section, the README, and the start, unblocked and status help describe epic branches. The skills already use <remote>/<base> and needed no change.
• Quest tree: deletes branch.md and its Required links in held.md and land.md. Records the settled recommendations in the epic README. Adds notes to land.md (the sync resolves quest files the same way readiness reads them, and how PRs into epic branches land until it ships) and to held.md (the epic PR's generic ## Waiting item).

Public API and wire impact

• CLI: quest start, quest unblocked and quest status (new base record and JSON field) behave as above. There are no new flags.
• GitHub: quest start can now create an upstream branch and a second draft PR (the epic's) on the first claim in an epic.

Choices made without asking

• The epic's draft PR is handed back with a ## Waiting item (- quest/<milestone>/<epic>: its quests merge into this branch first; this PR lands once none remain.). Without that item it would read as a stale claim by whichever session opened it. With it, /quest-iterate can take the README's own work once the quests have merged, and quest waiting lists every open epic until held.md replaces the item with what actually holds the epic.
• /quest-plan and /quest-audit PRs keep targeting main. This departs from the epic's recommendation. Readiness reads an epic's branch merged with main, so a planning edit counts as soon as it lands, and planning needs only one base. Recorded in the epic README.
• Nested epics (until no-nesting lands) target the branch of the epic directly under the milestone, so a quest's PR is always one hop from main.
• Plain quest unblocked reads epic branches from the remote-tracking refs (refs/remotes/<remote>/quest/...), so it makes no network call. --unclaimed and quest start read them from the remote.

Validation

• just check passes. just test passes; it first failed on the afk skill size limit, which moving the guide text into the Model section fixed.
• New tests:
  • test/unblocked.test.ts: mergeSources sides and deletions, and ranking across trees.
  • test/start.test.ts, "epic branches": first claim opens the branch and PR; a quest planned on the epic branch alone, claimed and explained; racing claims; fork refusal and a fork claiming on an existing branch; a landed branch and one at main replaced; a branch with commits but no PR given one; release; a quest finished on the epic branch; a main finish unblocking an epic quest; the README held by its epic's branch.
  • test/status.test.ts: the base line.
• Merged main after moq-dev/quest#603; the only conflict was the ./agent import in src/cli/main.ts, and the PR's diff against main is unchanged.
• This repository's Check workflow runs on PRs into any branch, and Queue only on main.
• The fake GitHub does not model the 422 GitHub returns for a PR whose head has no commits beyond its base. The tests instead assert that every epic branch an epic PR opens from has a commit ahead of main, and the fork test no longer opens a PR from a branch at main.

Limitations

• Until land.md ships, quest merge refuses PRs into an epic's branch, because that branch has no queue. After this merges, PRs for quests in queue-watcher, token-waste and epic-branches (land.md's own PR included) target epic branches and need GitHub's merge button when picked. Starting land.md next keeps that window short.
• Other repositories get this behavior only when their pinned quest is bumped. Whether their PR checks and online reviewers run on non-main bases is still open in the epic README.

Follow-ups

None beyond the epic's remaining children (land.md, held.md, no-nesting.md).

Caused by

No single PR caused this: it is new behavior the epic plans, reversing moq-dev/quest#44's removal of questline branches by design.

Reviewed commit: d6131ad

[P2] src/cli/start.ts:174–198: make an existing epic branch PR-able before opening its missing PR. If quest/<milestone>/<epic>/README already points at main and has no PR, epic.tip is non-null, so the empty-commit creation is skipped and openEpicPull submits identical head/base histories. GitHub returns 422 (no commits between them), and the fallback finds no open PR and throws, preventing every child claim. The new “a branch without a PR gets one” test constructs exactly this state, but FakeGitHub only models duplicate-PR rejection. When the existing upstream epic tip has no commits ahead of the base, add an empty commit with a lease before opening its PR (or explicitly refuse with recovery guidance when the caller cannot push upstream). Make the fake reject identical histories and cover this recovery.

Overall direction: the epic-specific readiness and target-base plumbing is coherent, but the advertised existing-branch recovery needs this fix. Verification limits: GitHub-only static review of the changed patches and relevant claim/branch helpers; no tests or live GitHub reproduction performed. Rechecked open/non-draft state, full head SHA and existing reviews immediately before posting.

Walkthrough

The CLI now merges default-branch and epic-branch trees for quest readiness and ranking. Quests within an epic use that epic’s branch as their claim base, and the first claim can create the epic branch and its draft pull request. Quest pull requests target the selected base. Status output now includes the pull request’s base branch.

Merge Risk: Minimal · up to d6131

The change adds epic-branch claims and a PR base field to status output. It has no demonstrated functional risk. Fix three small documentation inaccuracies when convenient.

Addressed the remaining automated findings on d6131ad in 63950af:

• P2 src/cli/start.ts:174, an existing epic branch with no commits beyond main and no PR: fixed. claimBase now treats an epic branch that the default branch already contains like a landed one, so the claim stacks the open epic commit on main with a lease on the old tip before opening the epic PR, and a fork refuses as it does for a missing branch. The tests now assert the stacked commit, and the fork test no longer opens a PR from a branch at main. I did not make the fake GitHub reject identical histories: it holds no repository history, and the assertion that the epic branch gains a commit ahead of main covers the same property.
• CodeRabbit, outside the diff, README.md:510, base missing from the quest status --json field list: fixed.

Reviewed commit: 63950af

Compared with d6131ad; base remains eaa0831. My earlier P2 is fixed: src/cli/start.ts:90–91 detects an epic tip already contained in the default branch, routing it through empty-commit creation with a lease on the existing tip. Forks get recovery guidance instead of attempting the upstream write. The updated tests assert the new parent/child commit chain and preserve an existing ahead-of-main branch.

No new actionable findings in the incremental changes. Overall direction is sound; the README target/base-field corrections also match the implementation. Verification limits: GitHub-only static comparison and inspection, no builds/tests or live PR creation run. The fake still does not simulate GitHub's identical-history 422, but the added ancestry assertions directly cover the reported defect. Rechecked open/non-draft state, full head SHA and reviews immediately before posting.

The land fixer works on it in the background, and the watcher re-enqueues it at the back of the queue once it is fixed or judged flaky, or hands it back here with what it needs.
