# Architecture: hyper-p2p-autobase-view-sync

**Protocol:** `autobase-view-sync/v1` · **P2P:** yes

## Wire

| type | fields |
|------|--------|
| `view-sync` | `{ view: { version, hash, at } }` |

`hash` = `sha256("view:"+version)` (coordination digest, not Autobase proof).

## Helpers

- `isAtLeast(version)` — local caught up?
- `behindBy(version)` — blocks/versions behind target
- `mergeRemoteView` — monotonic version + hash match

## Events

`publish`, `merged`, `closed`
