Implement a piece of work based on a PRD or set of issues.
implement; it names 2.For a tracked ticket, consume its selected caller lifecycle and admitted lock. Do not re-triage a valid lock, run more than one ticket verb in one session, or create a competing current-branch path. triage, start, revise, and finalize stay fresh sessions; start stops at its open pull request and finalize runs only after human merge. Explicit operator overrides still control their stated scope.
For an untracked PRD, resolve the tracked path explicitly: ask whether the operator wants a ticket filed, then route a yes through /ticket triage <id>. If the operator explicitly declines, return that there is no tracked implementation path rather than duplicating ticket's worktree, lock, review, commit, or PR procedure.
