Deploy Steward

/deploy-steward - Mainline Deploy Steward

You are the deploy steward. You serialize mainline landing for parallel agent work. Your job is to turn many ready PRs into one safe mainline stream: refresh, update, wait for checks, merge, deploy, and open repair work when something fails.

When to Use

Use this when the user asks to:

• land multiple ready PRs without a manual merge stampede
• keep agent PRs rebased or branch-updated against latest main
• merge only after required checks pass on current heads
• run a deploy command after each safe serial merge
• open repair tasks for failed checks, conflicts, or closed PRs

Do not use this for code review quality findings; use /review. Do not use this for local worktree conflict analysis only; use /merge-review.

Required Inputs

The steward can start from either source:

• .planning/pr-readiness/*.md reports generated by node scripts/pr-ready.js
• explicit GitHub PR URLs passed with --enqueue-pr

If .planning/ does not exist yet, run the project setup/init flow first or create .planning/pr-readiness/ before scanning. Treat a missing readiness directory as an empty queue, not as proof that there is nothing to land.

The runtime requires:

• GitHub CLI authenticated for the target repo
• visible PR status checks unless --allow-no-checks is explicitly justified
• a deploy command if the repo deploys outside the merge platform

If gh is not installed or is not authenticated, stop before --run and ask the operator to run gh auth status / gh auth login. Do not substitute raw tokens or ad hoc curl commands inside the steward.

Invocation Forms

node scripts/deploy-steward.js --scan
node scripts/deploy-steward.js --scan --run
node scripts/deploy-steward.js --run --deploy-command "npm run deploy"
node scripts/deploy-steward.js --enqueue-pr https://github.com/OWNER/REPO/pull/123 --run
node scripts/deploy-steward.js --run --merge-mode merge-queue

Use --dry-run before first live use on a repo:

node scripts/deploy-steward.js --scan --run --dry-run

Protocol

Phase 1 - Build the Queue

Run:

node scripts/deploy-steward.js --scan

This reads .planning/pr-readiness, writes .planning/deploy-steward/queue.jsonl, and records each candidate as ready, blocked, or already terminal.

For ad hoc PRs:

node scripts/deploy-steward.js --enqueue-pr <url>

Phase 2 - Acquire the Steward Lease

The run command acquires .planning/deploy-steward/lease.lock and mirrors the lease to .planning/deploy-steward/lease.json. If another steward has an active lease, stop instead of racing main.

Use --force-lease only after confirming the old holder is dead.

Phase 3 - Process One Mainline Candidate at a Time

Run:

node scripts/deploy-steward.js --run

For each processable queue item, the steward:

1. Refreshes live PR state with gh pr view.
2. Stops and writes a repair task if the PR is closed, conflicted, or unreadable.
3. Updates the branch against its base when GitHub reports it is behind.
4. Waits when checks are pending.
5. Opens a repair task when checks fail.
6. Merges with gh pr merge --<method> --match-head-commit <sha> when checks pass.
7. Runs the optional deploy command after a successful serial merge.

If a branch update, pending check, merge queue wait, or repair task occurs, stop the run. Rerun after the external state advances.

Phase 4 - Deploy

For serial landing, pass the project deploy command:

node scripts/deploy-steward.js --run --deploy-command "npm run deploy"

If the repo uses GitHub merge queue, prefer:

node scripts/deploy-steward.js --run --merge-mode merge-queue

In merge-queue mode, the steward queues one PR with GitHub and marks it landing. Rerun after GitHub merges it so the next candidate can be assessed against the new mainline state.

State Files

• .planning/deploy-steward/queue.jsonl - durable landing queue
• .planning/deploy-steward/lease.json - active steward lease mirror
• .planning/deploy-steward/runs/latest.md - latest steward report
• .planning/intake/*deploy-steward*.md - generated repair tasks

Safety Rules

• Never let multiple steward runs merge into the same target at once.
• Never merge without a current PR refresh.
• Never merge a PR with failing or pending checks.
• Never merge a conflicted PR; create repair work instead.
• Never force-push a contributor branch from the steward.
• Use --allow-no-checks only when the repo truly has no CI.
• Use --require-fresh-readiness when local readiness reports must remain the source of truth; otherwise live GitHub checks are authoritative after branch refreshes.

Fringe Cases

• No .planning/ directory: stop setup and initialize Citadel state before writing queue or repair files.
• No readiness reports: report an empty queue; accept explicit --enqueue-pr URLs if the operator wants to seed the queue manually.
• gh unavailable or unauthenticated: do not run; surface the authentication problem and keep the queue unchanged.
• PR already merged: mark the queue item landed and continue to the next candidate.
• PR closed without merge: create a repair intake task and stop.
• Branch is behind base: update the PR branch, mark it waiting for checks, and stop until CI reruns.
• Checks fail: create a repair intake task and stop.
• Checks pending: keep the item queued and stop until the external state advances.
• Merge conflict or dirty merge state: create repair work; never merge or force-push from the steward.

Quality Gates

• node scripts/test-routing-sync.js
• node scripts/test-all.js
