Run GitHub Project

Core Principle

The Project is the live control plane. Apply these invariants throughout:

1. Live authority: use complete, fresh GitHub and Project state for every claim, selection, and finish decision; a local cache or partial read is only a hint.
2. Controller ownership: the controller alone claims, assigns, mutates shared Project state, merges, closes issues, and reconciles. A ticket agent owns only its worktree, branch, and non-merge PR mutations.
3. Unknown outcomes: treat a failed or timed-out remote mutation as unknown; authoritatively reconcile it before retrying or reporting success.
4. Preservation: retain blocked, dependency-gated, and human-owned work. Put it in its authoritative frontier or partial-drain report rather than changing its state to make the queue appear empty.
