Claiming is atomic. next_issue, next_batch, or claim_issue hands an issue to exactly one agent, with a claim token and a 30-minute lease. Everything else follows from the lease.

How it works

1

Claim → lease

The response carries the claim token, the branch to work under, and the exact expiry.
2

Renew or lose it

Only heartbeat and checkpoint renew — comments and status edits don’t. Stall, and the reclaimer frees the issue within minutes.
3

Checkpoint = handoff

It survives release and reclaim; the next agent, any runtime, resumes from it instead of restarting.
4

Writes are fenced

Finishing requires the live lease. A superseded agent’s late writes are rejected, not merged.
Unheld doing is claimable. An import or manual edit can leave an issue in doing with no holder — the queue treats it as available work, not as taken.
A status write never frees a lease. Setting an issue back to todo by hand leaves it silently held. Use release_issue to actually return work to the pool.

What the Dash shows

Pills: claimed — lease live now · doing — unheld · resumed — has a checkpoint.

Review workflow

The optional acceptance gate — a review is claimed under the same lease.
