Opus final review of B.4c flagged that Task 4's handoff doc invented
implementation details that don't exist in the code:
1. IsDoorSpawn claimed to check "spawn.WeenieObj.WeenieType == 8 OR
IsDoorName(spawn.Name)" — the actual code is just IsDoorName(spawn.Name)
delegating to "name == "Door"". No WeenieType lookup exists.
2. A "_doorSequencers" per-door dict was referenced in three places — that
dict doesn't exist. The actual code reuses the existing
_animatedEntities[entity.Id] dict (same one that holds creatures + the
player), with Animation = null! per the existing pattern at line 7885.
3. The UM dispatch path was described as a new B.4c-added branch with
pseudocode — that's wrong. B.4c does NOT add a new dispatch path;
OnLiveMotionUpdated's existing TryGetValue against _animatedEntities
handles doors automatically once Task 1's spawn-time branch registers
them. The only UM-dispatch B.4c contribution is the [door-cycle]
diagnostic line, gated on IsDoorName.
Corrects sections "At world load (spawn time)", "When the door opens",
"Per-frame mesh rebuild", and "Door types covered" to reflect the actual
shipped code. cmd→motion mapping (cmd=0x000C → open, cmd=0x000B → close)
left as-is — it was correct.
No code change. Verified by re-reading GameWindow.cs IsDoorSpawn /
IsDoorName helpers, the Task 1 spawn-time branch body, and the
TickAnimations sequencer dispatch.
