Phase 1 audit confirmed no Ticket dataclass access sites need migration:
- Ticket dataclass consumers in _spawn_worker, mutate_dag, and
multi_agent_conductor.run already use direct field access
- The t.get('id', '') style sites operate on dicts
(self.active_tickets: list[Metadata], topological_sort returns list[dict])
- These dict sites are correctly classified as Metadata collapsed-codepath
per spec FR2
35/35 tests pass. No code changes needed.
