Types 14/19/38/44 declare their Index{1,2,3} fields as a union with a
pointer, so on PC each is an 8B/8-aligned slot (Index1@8, Index2@16,
...) and the record ends in a *next the proplvreset2 walk writes. The
converter was laying the N64 tight-4-byte index words at PC bytes 4/8/12,
putting Index1 where the compiler reads Index2 and leaving Index2 zero.
Non-crashing but silently broke switch-doors, dual weapons, padlocked
doors, and safe/safe-item links.
- tools_pc/d88_propdefs.py: PROPDEF_PC_BYTES 14/19->32, 44->40; handler
emits Index{k} into low 4B of the 8-aligned slot at PC 8+8*k.
- loadobjectmodel.c sizepropdef() PORT: LINK/SWITCH/LOCK_DOOR->8,
SAFE_ITEM->10, TAG stays 6.
Verified: -level_09 framediff 3/3 PASS; -level_20 identical to a
freshly-built pre-D132 baseline (frame_000320 delta is pre-existing
stale-golden/Silo slowdown, not a regression); Archives/Streets/Dam
