Adds inline failure debugging to the Phases tab. When you see a
phase card marked FAILED, click the collapsed error summary and the
full topology_run.error text expands under it — the exact stack
trace / provider error / whatever the worker recorded.
Backend:
- TopologyRunSummary gains mission_phase_id + team_id + error
fields. list_by_mission SELECT extended; other constructor
(list_recent) explicitly passes None for the new fields.
- GET /api/missions/{id}/runs response now carries all of the
above so the frontend can attribute failures per phase.
Frontend:
- MissionRunSummary type mirrors backend additions.
- MissionCanvas fetches runs alongside mission on load +
auto-refresh; indexes by mission_phase_id in a memoized Map.
- Each phase card renders a per-run row: colored status pill
(running / completed / failed), short run id, finished_at
timestamp. For failed runs, a <details> collapses the error
text — first line as summary, full 4kB in a monospace <pre> on
expand.
Directly unblocks the "phase says Failed but there's no info to
debug" report. Both research and coding phases get this — the code
path is phase-kind-agnostic.
