## Definitions

### `com.lopecode.bundle.version`

**Type**: `record`

An append-only snapshot of a com.lopecode.bundle record taken at the moment immediately before that bundle was overwritten. Snapshots keep prior blob refs reachable from the current MST so the PDS does not garbage-collect them, and form a parent-pointer DAG via previousVersion. Snapshot rkeys are `<bundleRkey>--<tid>` so all snapshots for one bundle share a common rkey prefix and can be retrieved with a server-side range query.

**Key**: `any`

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `record` | `unknown` | Yes | Verbatim copy of the prior bundle's value, inlined so its embedded blob refs remain reachable from the current MST. Forward-compatible: future com.lopecode.bundle field additions require no schema changes here. |
| `versionOf` | `string` (at-uri) | Yes | AT-URI of the live com.lopecode.bundle record this snapshot was taken from (same did, same bundle rkey). Redundant with the rkey prefix but kept for self-describing snapshots. |
| `previousVersion` | `string` (at-uri) | No | AT-URI of the snapshot that this snapshot descends from, forming a parent pointer chain. Null/absent on the first snapshot in a chain. Multiple snapshots may share the same previousVersion (forks). |
