The two deferred TakeDamage dispatches in Mech::ProcessCollision now fire,
unblocked by STEP 6 (the cylinder hit-location override that resolves zone==-1):
- Mover branch (:15324-15358): on a collision with another Mech, dispatch the
collision damage to it.
- CulturalIcon branch (:15369-15401): crunch dispatch to a building/tree/prop,
before the walk-through sentinel overwrites the amount.
Both go through a new file-scope helper BTDispatchCollisionDamage, which builds
an Entity::TakeDamageMessage{zone==-1} (the engine ctor -- same idiom as the
weapon-impact path) with the world centre of the overlap slice as the impact
point and this mech as the inflictor, then Dispatch()es it to the victim. The
receiver turns the world impact point into a damage zone: a Mech via its cylinder
table (STEP 6), an icon via its base handler (crushable props have no zones -> a
harmless no-op). Terrain (walls/hills) matches neither branch, so it still
BLOCKS without damage (faithful to the binary).
Faithful to the binary's raw DamageMessage dispatch (:15324-15401) but via the
engine's named TakeDamageMessage API (no databinding-trap field-by-field build);
the binary's inflictor global DAT_0050b9ac is a sentinel EntityID (only ever
read, never set -> a collision has no "shooter"), so this mech is the inflictor.
Verify: builds clean; reachability GUARANTEED (Mover::ProcessCollisionList calls
the VIRTUAL ProcessCollision -> Mech::ProcessCollision, on the active
AuthenticGroundAndCollide path); stable across runs; both mechs build their
cylinder tables. The live dispatch was not captured headlessly (the solo
auto-walker never rammed a tree/mech), but the path is proven reachable and
composed of runtime-verified pieces (the weapon TakeDamage path + STEP 6).
Also validated STEP 6's height ref: collisionTemplate->maxY ~= 7.1 (a real mech
height), confirming CylinderReferenceHeight reads a height (not the heat value
the mech+0x2ec dual-labeling hinted at).
