- `quality & 0xFF` is the subtype selector for the authored family-4 usecode class.
- The runtime resolves that class as `0x0900 + QLo`.
- The currently verified authored subtype sets are:
- Remorse: `QLo 0, 1, 2, 13` -> `TRIGEGG`, `ONCEEGG`, `FLOOR1`, `MISS1EGG`
- Remorse: `QLo 0, 1, 2, 4, 13` -> `TRIGEGG`, `ONCEEGG`, `FLOOR1`, `CHANGER`, `MISS1EGG`

That is why the renderer now treats `0x0011` as a proximity/usecode-trigger egg with a projected footprint overlay, a subtype-aware USECODE landing point, and only the narrower local-arrow rules that are actually justified by the recovered subtype body.
One checked Remorse example now makes the `CHANGER` subtype concrete.
- Map 13 `fixed:4770` is `item:12473:fixed:17:0:47888:53256:96` with `mapNum = 37`, `quality = 4`, and `npcNum = 64`.
- `quality & 0xff = 4` resolves the usecode class to `0x0904`, which matches the extracted Remorse `CHANGER::hatch` body.
- `CHANGER::hatch` reads `eggNum = Egg.getEggId(arg_06)` from `mapNum`, walks nearby `roof` candidates, compares each candidate's low quality byte against that egg id, and destroys the matching roof when `Item.getQLo(roof) == eggNum`.
- The same local decoded scene contains nearby roof placements (`shape:538`, kind `roof`) whose `quality & 0xff = 37`, matching the egg id from `mapNum`.
Current safest read for `CHANGER` is therefore `keyed roof-destruction trigger`, not generic collision override logic and not a Regret-only family-4 subtype.
