Brigade work session ended: {_slug(str(title))}

## Summary

A Brigade work session was ended and local session artifacts were written. This handoff captures the session path, final git state, latest dogfood run, and extracted next step so the memory owner can route durable workflow context.

## Durable facts

- session: `{payload.get('id')}`
- target: `{target}`
- session artifacts: `{session_dir}`
- status: {payload.get('status')}
- started: {payload.get('started_at')}
- ended: {payload.get('ended_at')}
- note: {note or 'none'}
- branch: {git.get('branch') if isinstance(git, dict) else 'unknown'}
- dirty files:
{dirty_lines}
{latest_line}
{next_line}

## Evidence

- session.json: `{session_dir / 'session.json'}`
- start summary: `{session_dir / 'start.md'}`
- end summary: `{session_dir / 'end.md'}`
