The shared state a sequence of over applications rides — constructed once per
document evaluation AND once per op-bridge apply session (the applicator,
plans/operation-bridge.md fixture 2):
async entity chaining: entity-targeted overs and entity-ref values await the
entity's instantiation; overs touching the same entity keep their order among
themselves by chaining on the entity's tail promise. Non-async overs apply
synchronously (pre-awake); settled() awaits the async remainder.
deactivated subtrees ("active": false → removeFromParent), per scope ref:
materials are RESOURCES, not graph nodes — a material used only by a
deactivated mesh must stay addressable (doc order legally deactivates first
and patches after), so material resolution searches these detached roots too.
