<a id="verification"></a>
## Verification

Extraction passed canonical-graph, root-digest, and reachable-type-digest validation, permitting the original optional `surfaceOp` only for historical surface events. The in-tree check reconstructs each tag from its predecessor and verifies before/after values, snapshot coverage, and bilingual machine declarations.

```sh
pnpm run verify-persistence-releases
```
