| 1 | """Phase 3 — Agent SPAWNS relationship committed to parent's identity repo. |
| 2 | |
| 3 | TDD regression suite: every test starts RED and turns GREEN as the feature |
| 4 | is implemented. Their permanent role is to prevent regressions. |
| 5 | |
| 6 | What this phase covers: |
| 7 | - register_agent_identity() commits a RelationshipRecord to the parent's |
| 8 | identity repo (not the agent's) |
| 9 | - The relationship file path is relationships/{parent}--spawns--{agent}.json |
| 10 | - The RelationshipRecord has correct from_handle, to_handle, edge_type |
| 11 | - The parent's identity repo gains exactly one new commit per agent spawned |
| 12 | - The agent's own identity repo is NOT modified (SPAWNS lives on the parent) |
| 13 | - No-op when the parent has no identity repo (migration-period safety) |
