The Mech per-impact hit-location resolver (the cylinder damage table) is now
functional, wired, and runtime-verified [T2]. Unaimed (zone==-1) hits — the
collision-damage path — now resolve an impact point to a damage zone via the
authentic height x angle grid + weighted dice roll, instead of dropping.
dmgtable.cpp/.hpp was a non-functional skeleton on no-op ReconTable/stream
shims; backed it with real std::vector storage and fixed 5 latent runtime bugs:
- ReadEntries now consumes the leading cell name-string ([i32 len][len+1])
- PieSlice ctor reads rotateWithTorso into the correct member
- SelectSlice direct-indexes (was int lookup on a float-keyed table)
- ResolveHit returns the zone (chains SelectSlice -> SelectZone)
- real MemoryStream::ReadBytes (was a variadic no-op)
mech.cpp ctor: replaced the empty-name StandingAnimation stub with the real
load — FindResourceDescription(dzRes->resourceName, type 0x1d) -> stream ->
new DamageLookupTable, cached at mech[0x111]; ~Mech deletes it.
Mech::TakeDamageMessageHandler override registered (MESSAGE_ENTRY overlays
Entity's by ID): on invalidDamageZone, resolve via the table then base-route;
aimed reticle hits pass through unchanged.
Three named accessors (no databinding-trap raw reads): WorldToLocal
(localToWorld.MultiplyByInverse), CylinderReferenceHeight (standingTemplateMaxY
== collisionTemplate->maxY == binary mech+0x2ec[+0xc]), TorsoHeading via a
BTGetTorsoTwist bridge in torso.cpp (Torso::CurrentTwist == torso+0x1d8;
torso.hpp cannot be included into mech.cpp — subsystem-stub collision).
Stream format + geometry + roll + handler were all byte-verified against the
shipped BTL4.RES type-29 resources (18 tables, exact consumption) and the
disassembly (FUN_0049eb54/e678/de14, glue 0x49ed0c, handler @0x4a037a).
Runtime: boots clean, "[cyl] table 'bhk1' layers=7" (exact byte-verified layer
count, found by name), mech spawns + walks, no asserts/AV/0xCDCDCDCD. Env gate
BT_CYL_LOG=1. Unblocks collision-damage application.

Per the 'correct errors' convention: the cited FUN_004a0230/FUN_0049ed0c don't exist. The real
CylinderDamageZoneTable = a list of 0x30-byte entries (FUN_0049e740) from resource 0x1d; the recon
builds the table (FUN_0049ea48, mislabeled StandingAnimation @Mech[0x111]) with an EMPTY name -> 0
entries -> no-op. The lookup + Mech::TakeDamageMessageHandler override are NOT in the exported decomp
(need disassembly). Recorded in combat-damage + open-questions.

Propagate the verified finding (0xBD3 = damage/explosion hub @0x434, NOT the valve/message
gate; the valve/Myomers gates read the owning BTPlayer @mech+0x190) into the topic files that
still carried the old claim: decomp-reference (ClassID row + both offset rows), gauges-hud,
subsystems, open-questions (Myomers coupling), + frontmatter. Graph validates clean.

The valve/Myomers 'gates' (FUN_004ac9c8 / FUN_004ad7d4) read the owning BTPlayer's
+0x274 / +0x260 (mech+0x190 = the player, bound by FUN_0049f624). So there's no new
subsystem to build -- the wiring is 2 gate accessors -> GetPlayerLink() named members.
Open: the true semantics of player+0x260/0x274 (scoring names showKills/roleClassIndex
may not match the gate use) + the FUN_004ad7d4 HeatModelActive-vs-OwnerAdvancedDamage
label conflict + these are likely MODE flags authentically-off in the basic mission.

Risk-4 investigation (before wiring WAVE 8) found my earlier 'keystone unblocks 4 things'
claim was wrong. Verified from the binary:
- 0xBD3 SubsystemMessageManager = a damage/explosion consolidation hub (ConsolidateAndSendDamage,
weaponExplosions), cached to Mech[0x10d]=0x434, mislabeled 'controlsMapper' in our recon (the
live drive squats there; the real mapper is roster slot 0 via SetMappingSubsystem).
- The valve MoveValve guard (FUN_004ac9c8 ->owner+0x190+0x274) AND the Myomers gate
(FUN_004ad7d4 ->owner+0x190+0x260) read a DIFFERENT object at mech+0x190 (!= 0x434). So 0xBD3
does NOT gate the valve/Myomers/MessageBoard; mech+0x190 (unidentified, no decompiled writer yet)
is the real keystone for those gauge-adjacent routes.
