# M2M-HANDOFF-01 — Root Capability Matrix

Status: `CANDIDATE REVIEW / NON-RUNTIME`

| Rule | Disposition | Evidence |
|---|---|---|
| SATOR mediates result and disclosure | already supported | root SATOR and five-class order |
| SATOR must not route/select next OPERA | already supported | offer-vs-route and class separation |
| AREPO evaluates downstream payload | already supported | AREPO validates whether downstream OPERA may proceed |
| admission is directional/scoped | already supported | AREPO modular admission extension |
| typed handoff does not schedule/admit/execute | already supported stack precedent | Arithmetica TENET XIX |
| path/transition/admission/traversal/execution remain distinct | compatible and explicit through Graph lifecycle candidate | M2M-GRAPH-01 |
| general handoff envelope fields | compatible but not explicit | candidate interface supplied here |
| consumer taxonomy | compatible but not explicit | candidate interface supplied here |
| automatic routing or upstream mutation | conflict | five-class and AREPO/SATOR boundaries |

Conclusion: no root-law mutation is required for a candidate typed handoff contract. A later canonical general envelope would require a separate promotion decision.
