- Add batch_id (UUID, nullable, indexed) and target_label (String 255, nullable) columns to the Session model - Manual Alembic migration 6e8128ef2aa8 applies both columns - POST /sessions/batch creates one session per target for maintenance flows; rejects empty targets (422) and non-maintenance trees (400) - SessionResponse schema exposes batch_id and target_label - 3 new integration tests, all 540 tests pass Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
