* Empirical Verification & Stress Test Suite: Monster Rendering Dispatch & Backwards Compatibility
|
|
* Milestone 2 (R2) — Challenger 2 Verification
|
|
*
|
|
* Requirements verified:
|
|
* - Pure additive monsters (WR, WW) with art.blendMode = 'additive'
|
|
* - Composite monsters (FR) with art.blendMode = 'normal' + art.glowGroups
|
|
* - Legacy unbaked packs (art.blendMode undefined) with ADDITIVE_MONSTER_TOKENS fallback
|
|
* - Regular monsters (FA, ZM) with blendMode = 'normal'
|
|
* - Corpse frame handling (1x1 empty dimensions skip glow pass cleanly)
|
|
* - Differential fuzzing (10,000 iterations)
|
|
* - Live inspection of samples/d2-packs/entities/
|
