# CAIN-A75-007 Physical Action Twin Review

**Verdict:** VERIFIED

> Recomputes an action plan against a SIMULATED digital twin: authority, envelope, zone geometry, deterministic simulation, penetration, human standoff and the plan's own claims. No hardware is contacted; a wrong world state gives a wrong verdict.

| Action | Twin | Verdict | Stop distance | Closest human | Failed checks |
|---|---|---|---|---|---|
| 0 move-vial-7-to-b | twin-lab-arm-1 v1.4.0 | SAFE | 0.16 m | 4.1231 m |  |

## What this proves and what it does not
- Proves: the plan's numbers are internally consistent and satisfy the declared envelope, the path geometry is inside allowed zones, the simulation is deterministic and covers the action, and the plan does not overstate its own result.
- Does not prove: that the twin matches the real robot, that the world state is current, or that the action is safe outside the supplied model. This is a simulation review, not hardware evidence and not a certification.
