Coordinate — origin/main is the only truth

The brief every session follows is .keelokit/harness/agent-brief.md (SESS-1). Read it once.

Start sessions

• One session per story, from the same wave (the doctor guarantees their touches don't overlap). Stories that add migrations go one at a time (MIG-1).
• The prompt is short: Read .keelokit/harness/agent-brief.md, then /keelokit:build-story <ID>. Pass paths, not contents; don't repeat the brief's rules.
• Respect the machine: at most two sessions running tests at once (pnpm verify takes a per-machine lock, so more only wait).

Every round (about every 15 minutes while sessions run)

1. python3 .keelokit/bin/status.py: worktrees, branches with commits not on origin/main, the verify lock, the CI of main (a cancelled run is not green) and the backlog, in ten lines.
2. For each session that says it finished: git fetch origin main && git log origin/main --oneline and find its commit (Story: <ID> trailer). A session that ends well does not message you; don't wait for a message, check the hash. "Done" without a commit on main is not done: send it back to land (rebase, pnpm verify, push) or land it yourself.
3. CI of main red, or two runs in a row without a green: stop starting stories; python3 .keelokit/bin/ci.py jobs says which job and step; fix that first.
4. Wait with one until loop on one condition, never with repeated polling.

Report to the user

Two lines per session at most: story, hash on main (or "not landed" and why), then what needs the user. The whole report fits in ten lines.
