## Definitions

### `app.thesocialwire.readState`

**Type**: `record`

Public canonical read/unread manifest. V1 uses head; V2 requires revision and compactionVersion=1 with separate state/device/legacy-receipt roots. Every root must be fully CID-verified before atomic activation. Maintenance revisions never invent user-action sequences.

**Key**: `literal:self`
