Advances #221

Outcome

  • Adds an AppGithubWriteback adapter from the connected GithubConnectionWrite to the orchestrator GithubWriteback lifecycle port.
  • Extends the Relayfile connection writer with confirmed GitHub issue comments and issue label/state updates.
  • Requires confirmWrite to acknowledge every App mutation; pending, failed, or timed-out writes reject.
  • Extends the guarded cloud-mount allowlist only for canonical issue patches and Factory deterministic comment drafts.

Selection and attribution

  • Exact github.identity: "app" selects the App lifecycle adapter at FactoryLoop construction and refuses local-gh fallback when the capability is absent.
  • auto and user retain the current local-gh issue lifecycle behavior. Existing auto PR publication remains App-preferred.
  • App mode sends PR publication, issue comments, lifecycle labels, and issue close through the workspace connection. Factory holds no GitHub credential; the server-side repo-capable App connection performs the provider mutation.

Deliberate scope

  • getIssueAuthor, getIssueStatus, and hasCommentMarker remain absent because provider-authoritative App reads are tracked separately in relayfile-cloud#159; existing callers keep their conservative optional-read behavior.
  • mergePolicy: "never" short-circuits real-issue merge-gate check/merge calls, so gh pr merge is not ported.
  • Notion intake owns a separate GhCliIssuePublisher surface and is unchanged.

Verification

  • npm run build
  • Changed-file suite: 685 passed across mount writer, writeback, orchestrator, and fleet CLI tests.
  • Final selection regression run: 3 passed (App/no-token must-fire, default-gh must-not-fire, missing capability fail-loud).
  • Guarded mount regression: 1 passed.
  • git diff --check and targeted credential-pattern scan passed.

Summary by cubic

Routes GitHub issue lifecycle writes (comments, status labels, close) through the connected App when github.identity is "app", preserving non-Factory labels and clearing all Factory lifecycle labels on "ready". The default "auto" keeps the local gh path for issues; "user" always uses gh.

  • Exact "app" selects AppGithubWriteback and refuses local-gh fallback if the mount lacks postIssueComment, ensureRepositoryLabel, mutateIssueLabel, or updateIssue. Provider-authoritative reads stay optional on the adapter.
  • Adds App-authored issue writes to GithubConnectionWrite via confirmed Relayfile drafts:
    • Deterministic comment drafts at /issues/{n}/comments/factory-{sha256-24}.json bound to the comment body.
    • Canonical partial issue updates at /issues/{n}.json (state-only for close).
    • Unique lifecycle label operations via /labels/factory-{uuid}.json and /issues/{n}/labels/factory-{uuid}.json.
    • confirmWrite must return acked; pending, failed, or timeouts reject.
  • Mount guard scopes App lifecycle drafts:
    • Always allow Factory-authored PR/ref/close artifacts.
    • Allow issue comment/update/label drafts only for configured repositories with an in-scope open issue; validate filenames, bind comment names to body content, and require exact repository label name/color/description. Installed for both ordinary CLI cloud mounts and direct library mounts.
  • Identity behavior: "user" always uses local gh; "auto" prefers App for PRs while keeping gh for issue lifecycle. Notion intake’s GitHub publisher is unchanged.

Written for commit 9d43700. Summary will update on new commits.

Review Change Stack

📝 Walkthrough

Walkthrough

The PR adds App-backed GitHub issue lifecycle writeback, deterministic and UUID-based draft paths, guarded draft authorization, identity-based writeback selection, public exports, and documentation for GitHub credential behavior.

Changes

GitHub lifecycle writeback

Layer / File(s) Summary
Mount write contracts and operations
src/ports/mount.ts, src/mount/relayfile-github-connection-write.ts, src/github/writeback-paths.ts, src/mount/*test*
GitHub mounts now support validated App-authored comments, repository labels, issue label mutations, and partial issue updates through confirmed drafts.
App writeback and identity selection
src/writeback/github.ts, src/writeback/index.ts, src/index.ts, src/orchestrator/factory.ts, src/config/schema.ts, README.md, src/writeback/writeback.test.ts, src/orchestrator/factory.test.ts
AppGithubWriteback performs GitHub lifecycle operations. Factory selection uses App identity for mounted App writeback and retains CLI behavior for other identities.
Guarded draft authorization and fleet wiring
src/orchestrator/factory.ts, src/orchestrator/index.ts, src/index.ts, src/cli/fleet.ts, src/cli/fleet.test.ts, src/orchestrator/factory.test.ts
Draft validation now checks guarded paths, payloads, repositories, lifecycle labels, and open Factory-scoped issues before dispatch.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to db727

Transitioning an issue to ready can leave the human-review Factory label behind on the local GitHub path, while the App path clears it, producing inconsistent issue state. This bounded correctness issue should be fixed or explicitly accepted before merge.

Poem

A rabbit checks each draft in line,
App labels bloom in states aligned.
Comments hop through guarded gates,
While UUID paths secure their dates.
“gh” waits when App writes arrive—
Factory’s GitHub flows now thrive.

Final implementation evidence for this head

Head 0c03125 is green in CI run 32021207049 (all five jobs). Local build passed; the four affected suites passed 685 tests. The latest review fixes make ready remove both Factory lifecycle labels, reject lifecycle drafts against closed issue projections in both CLI and direct-library mounts, and restore the exact comment-digest negative case. All nine previously unresolved threads were re-enumerated after code/tests and are now resolved.

The required server half is relayfile-cloud PR #162 at cd7cd55156f78e198fd097bc72c29327c9ee5bf6; its CI run 32021250233 is green and its review queue is clear. It implements confirmed repository-label ensure plus delta-only issue-label add/remove through the stored App connection, including full definition repair/confirmation and executor-level success/failure ACK tests.

Credential-free selection remains explicit: cloud must set github.identity=app. App mode refuses local-gh fallback; auto/user are unchanged. Do not remove FACTORY_GITHUB_TOKEN yet: neither PR is merged/deployed, and no live App-authored PR/comment probe has run against the cutover host. Full checkpoint: #221 (comment)

githubIssueReadCandidatePaths accepts a complete issue path, not repoPath. Extend it, or add an identity-based helper, to generate all supported aliases for { owner, repo, number }, including plain, by-id, meta.json, and metadata.json paths. Use that helper here.
