+  Every other leaf's rewrite binds bytes.
 - `leaf-record.msgpack`: `[members, payload]` for one `cultcache.leaf-record` document holding every leaf. `members` are
   the catalog rows the single-file store writes, each `[slot, memberName, typeName, isReference, isMany,
   targetSchemaName, isName, indexAlias]`; `payload` (bin) is the record's bytes in that store.
