Feature 120 (FR-007): the payload of `SceneNode.CachedSubtree` — a stable subtree identity, a collision-resistant structural fingerprint of its render-affecting inputs, and the wrapped subtree itself (both the record source and the transparent fallback).

Record fields

Record Field	Description
`CacheId` Full Usage: `CacheId` Field type: `uint64`	Stable subtree identity (from `RetainedId`) — the replay cache slot. Field type: `uint64`
`Fingerprint` Full Usage: `Fingerprint` Field type: `uint64`	Collision-resistant structural fingerprint of the wrapped subtree's render-affecting inputs; replay is valid iff a cached picture's fingerprint matches this. Field type: `uint64`
`Scene` Full Usage: `Scene` Field type: `Scene`	The wrapped subtree — record source and transparent fallback. Field type: `Scene`
