# Transition State Table

| Stage | Required evidence | Effect |
|---|---|---|
| structural connection exists | exact topology ref/status | availability only |
| directed transition declared | source/target refs and direction | directional possibility only |
| source result available | immutable operatum ref/hash | candidate payload source |
| SATOR payload mediated | schema, provenance, loss | candidate operandum only |
| target AREPO evaluates | current target TENET/ROTAS and epoch | admit/reject/suspend |
| transition admitted | scoped AREPO decision | traversal may be attempted |
| traversal recorded | exact transition and state delta | run history only |
| downstream OPERA executes | own current contract/admission | independent execution |

`PATH != TRANSITION`; available != admitted; admitted != traversed; traversed != executed.
