Mech::DamageZone::TakeDamage is the full binary cascade (@0049c690): LOD
artifact router with same-attacker clustering (@0049c40c, hysteresis 0.33),
artifact parent level = mean of children, Energy-hit generator shorts
through the crit plug binding (novice-exempt), weighted CriticalHit
(@0049ccc4), zone-death allotment push (SendSubsystemDamage @0049c9a8) and
the segment-table destruction descent (RecurseSegmentTable @0049cad4 --
SIBS + DESCEND via the engine EntitySegment iterators).
Supporting bricks: Mech's OWN handler table with the TakeDamage override
(latches lastInflictingID @0x43c; gyro feed staged; cylinder table
deferred); friend class Mech__DamageZone (authentic); subsystem private
zones ARMED (structureReference + armorByFacing[5] normalized -- crits are
measurable); ApplyDamageAndMeasure; ForceCriticalFailure sets
DestroyedState so the weapon FSMs' GetSimulationState()==1 hard gate went
live; Generator::ForceShort + PoweredSubsystem::ForceShortRecovery.
Fight-verified (mutual BT_SPAWN_ENEMY + BT_FORCE_ZONE=8 concentrated fire):
arm zone to 1.0 -> sibling searchlight zone dies (Searchlight2/ThermalSight
crits destroyed, HUD degrading) -> DESCEND kills the gun zone -> PPC_2 +
ERMLaser_2 + Condenser6 DESTROYED and FALL SILENT (0 shots after death;
undamaged PPC_1 keeps firing); vital-zone hit = MECH KILL; PPC hit shorted
GeneratorD. This art has zero artifact zones (redirect=0 across all 20 --
router verified dormant-correct). Smoke + novice regressions clean.

The subsystem-family cockpit buttons now work through the authentic Receiver
dispatch -> per-class handler-table path. The id space decodes cleanly:
Receiver::NextMessageID == 3, so ToggleCooling = 3 on the HeatSink chain and
the per-class id 4 is MoveValve on a Condenser / InjectCoolant on the
Reservoir -- same number, different class, the binary's per-receiver-class
convention.
- HeatSink::ToggleCoolingMessageHandler (@004ad6f8, id 3): novice-locked,
press-only; toggles coolantAvailable + coolantFlowScale together.
- Condenser::MoveValveMessageHandler (@4ae464, id 4): novice-locked; cycles
the valve 1->5->50->0->1 and calls Condenser::RecomputeValves (@0049f788):
every condenser's coolantFlowScale = valve / sum-of-valves. The ctor now
streams the AUTHENTIC flowScale=0; the Mech ctor seeds equal shares once at
spawn -- the flowScale=1 interim is retired.
- Reservoir::InjectCoolantMessageHandler (@4aee70, id 4): novice-locked;
press arms the flush when the tank holds charge, release drops it.
- MechSubsystem::NoviceLockout() (@4ac9c8): owner -> playerLink -> experience
== novice; unlinked mechs read unlocked.
- DEV harness BT_PRESS_VALVE / BT_PRESS_FLUSH: dispatch the REAL messages ~6s
into the mission from Mech::Simulate.
VERIFIED: spawn shares 6 x 0.166667; one MoveValve press -> Condenser1
valve=5 flow=0.5, others 0.1 (valve/sum exact); flush arms via the real
button message; NOVICE locks both presses (valve lines stay spawn-only, zero
flush). Zero Fail throughout.

The base all ~30 mech subsystems derive from. Reconstructed against the 4.10
structure per the MECHSUB.NOTES analysis (NOT backdated from BT411's divergent
version):
- Header: expanded with the real mech-specific member set (statusAlarm =
AlarmIndicator, vitalSubsystem, alarmModel, criticalReference,
collisionCriticalHitWeight, printSimulationState, configureActivePress,
resource). Dropped the speculative MessageHandlers static -- MechSubsystem
reuses the base Subsystem sets (inherited Simulation handlers/attrs/statecount).
- CPP: statics (ClassDerivations/DefaultData), both ctors (light name+classID and
resource), dtor, TestClass/TestInstance, and the damage API on the 4.10
per-type model -- GetSubsystemDamageLevel/SetSubsystemDamageLevel read/write the
real DamageZone::damageLevel [0,1]; ForceCriticalFailure; TakeDamage delegates
to the zone. Both ctors build the damage zone the base leaves NULL.
Deferred (documented): the Mech__DamageZone per-type armour STREAM wiring (ctors
use a trivial armour-free base DamageZone placeholder for now) and
CreateStreamedSubsystem (model-load stream format). These are refinements above
the ctor frontier, not boot blockers.
Compile-verified (BT: 24 ok); full tree still links clean. Next: the subsystem
roster (GAUSS/PPC/SENSOR source + .TCP partials + decomp).

All 10 surviving original TUs plus the reconstructed BTL4APP.CPP pilot build
clean with the authentic OPT.MAK flags (compile410.sh --sweep). First time
the 4.10 BattleTech source has compiled since 1996.
- layout_probe.cpp: the period compiler measures 1995 layouts from the
surviving headers; validated 3/3 against binary alloc sizes (BTMission
0xFC, BTL4ModeManager 0xC, BTRegistry 0x10). Base boundary: Simulation
0xD0 / Entity 0x1C4 / Mover 0x300 / JointedMover 0x328 => Mech-own region
0x328-0x854 (MECH-LAYOUT.md staging worksheet).
- 13 staged headers close the family ([T3] reserved[]-parked layouts;
interfaces PROVEN by the surviving consumers): MECH, MECHSUB, HEAT,
POWERSUB, MECHWEAP, EMITTER, MECHMPPR, BTPLAYER (BTPlayer__MakeMessage =
Player's 8 args + roleName/teamName [T1 via BTREG]), PROJTILE, MISSILE,
BTL4MPPR, BTL4VID + the round-2 BTCNSL/BTSCNRL.
- compile410.sh: PCH gate retired (bt.hpp/mungal4.hpp full include sets),
DPL SDK roots on the include line.
- BTL4APP.CPP: appmgr include + GetApplicationManager()->GetFrameRate() +
ResourceDescription:: scoping; Fail() held at its recorded line 400.
- Evidence ledgers: STAGED-HEADERS.NOTES.md, MECH-LAYOUT.md, BACKFILLS,
BTCNSL (binary-recovered console wire IDs), BTSCNRL.
Remaining for a linkable BTL4OPT: the ~40 missing TU bodies (917-function
manifest) - the header skeleton they grow into now exists and compiles.
