`POST /snapshots/{id}/fork`

Creates count sandboxes from the snapshot (query param or body; body wins). All-or-nothing: a mid-fork failure rolls back. The optional body's publish maps host ports onto the fork (docker -p semantics); publish requires count 1 because host ports are exclusive.

### Authorizations

- `bearerAuth` — HTTP bearer. Daemon API key. Omit on a keyless loopback daemon.

### Path parameters

- `id` string · required — Snapshot ID, e.g. snap_ab12cd34.

### Query parameters

- `count` integer · optional — Number of sandboxes to fork (default 1). The body's count wins when both are set.
