Death = the burning WRECK-HULK swap (effect 104) -- the authentic chain, reconstructed

Browse Source 
The user was right: a dead mech turns into a pile of wreckage.  The authentic
1995 chain, recovered end-to-end:

  kill -> the victim's per-mech DEATH ModelList ('blhdead'/'lokdead'/'owndead'/
  'thrdead', .RES ids 22-25) -> its authored effects: 104 (the WRECK script) +
  1007 (dnboom big explosion) + 1001 (ddthsmk rubble smoke plume) + a damage-
  smoke burst (3/4/5/15).

Effect 104 = ExplosionScripts case 4 (part_008.c:2663, LIVE in the 1996 binary;
the "disabled" warning is case 6): loads the destroyed hulk + flamesml/flamebig
flame meshes with sweep flicker.  Every mech ships its hulk (BLHDBR/MADDBR/
LOKDBR/... + GENDBR generic); the 1996 script hardcoded thrdbr.bgf (dev
shortcut) -- we use the victim's own.

Reconstructed as BTL4VideoRenderer::SwapToWreck: hide every segment mesh, hang
"<prefix>dbr.bgf" on the tree root (pending-swap if death precedes tree build);
routed from the engine's ExplosionClassID dispatch (effect 104 ->
BTSwapMechToWreck(explosion->GetEntityHit())).  The kill now fires the
authentic 'blhdead' resource (manual 7+1 pfx calls removed -- the list carries
1007/1001 itself).  Verified live:
  [death] firing authentic death list 'blhdead' id=22
     ** effect_number = 104
  [BTrender] wreck swap: victim -> 'blhdbr.bgf'

Follow-ups noted: mesh flames + hulk settle (cosmetic), DeathSplash.
