"""Run one Phoenix issue through the factory.
`start` checks that the issue is ready for the factory, routes it to a lane from its
triage labels, and creates a Managed Agents session that mounts the repo and grades the
lane's rubric as the session outcome. `watch` waits for that session, sends failing
required checks and then automated review findings on its PR back to it, marks the PR
ready for review once required CI passes, and reports the result on the issue. Agent,
environment and vault IDs come from claude-lock.json, which `ant apply` writes.
