- POST /agents/{name}/invoke, GET /executions, GET /executions/{trace_id},
POST /executions/{trace_id}/{approve,reject}.
- execution_index.json persiste trace_id → (agent_name, version) para reconstruir
el contexto en approve/reject tras un reinicio.
- Refactor del orchestrator: split _snapshot → _build_execution + _snapshot, nuevo
método público snapshot() (lee estado sin avanzar). Sustituye a los helpers
_snapshot_execution/_build_graph_for_snapshot del plan, incompatibles con el
checkpointer por-llamada.
- Aliases Annotated[...] de dependencias movidos a deps.py.
- Fixture mínima tests/fixtures/policies/default/.
