The "prepEngr" cockpit primitive (the per-engineering-screen static label overlay,
12 CFG calls at L4GAUGE.CFG:4595-4759) was a MISLABELED stub (base Gauge, an Execute
override, mech/screenNumber SWAPPED) with no methodDescription -> parse-SKIPPED, none built.
Reconstructed byte-verified (ctor @4c7bf0, BecameActive @4c7e48, Make @4c7b30; vtable
0051a06c). THREE corrections vs the stub (decode workflow + vtables.tsv proof):
(1) base = GraphicGaugeBackground, not Gauge -- vtable-identical shape to the engine's
BackgroundBitmap (only dtor + BecameActive overridden); (2) the overridden slot is
BecameActive (a paint-on-activation), NOT Execute -- GraphicGaugeBackground has no Execute
virtual, so the Gauge::Execute->Fail->abort hazard doesn't apply; (3) screenNumber@0x6C /
mech@0x70 were swapped. sizeof 0x90.
BecameActive walks the mech roster (databinding-safe GetSubsystemCount/GetSubsystem +
BTGetSubsystemAuxScreen bridge, like VehicleSubSystems::Make), finds the subsystem whose
auxScreenNumber == this screen (1..12), and paints the screen-number numeric + subsystem
label + type-specific label cells dispatched on GetClassID (Sensor/Myomers/Emitter/PPC/
Projectile/Missile/GaussRifle). methodDescription = 9 params (mode, screen, 7 .pcc names).
Registered in BTL4MethodDescription[]. Two raw subsystem reads (heat-sink #, +0x224 label)
are guarded fail-soft best-efforts (marked; the aux-screen bridge label64 substitutes).
VERIFIED: the skip list drops from {prepEngr x12, messageBoard} to just {messageBoard} --
all 12 prepEngr gauges build; no screen-range/crash; boot+sim+combat run; gauge composite
renders identically (COOLANT 300/77, clusters, radar all un-regressed). The prepEngr labels
paint on the Eng (ModeMFD*Eng*) screens, not the default composite view.

The "sectorDisplay" cockpit primitive (Secondary overlay, the radar SECTOR X/Z
coordinate read-out) was PROSE-ONLY in btl4gau3 (placeholder Make, no ctor/
methodDescription/registration) -> the config line was parse-SKIPPED and never built.
Reconstructed byte-verified from the disassembly (ctor @4c9e10, Execute @4ca07c,
methodDescription PE-parse): SectorDisplay : GraphicGauge, sizeof 0xC4. Its Execute
reads the linked mech's world position and shows two 100-unit sector numerics:
numericA = Round(-localOrigin.z * 0.01) + 500
numericB = Round( localOrigin.x * 0.01) + 500
(rounding = round-to-nearest == FUN_004dcd94, corrected from the reviewer's wrong
"truncate" claim; 0.01 const PE-verified; -Z/+X axis + fchs confirmed from asm).
Overridden slots: LinkToEntity(9) caches the subject, BecameActive(3, non-inactivating),
Execute(16) -> satisfies the container-Execute rule. Layout overflow-locked
(static_assert sizeof<=0xC4). Make/ctor/dtor mirror the registered PilotList sibling;
the config image name is copied (nameCopy) since Execute reads it per-frame.
Registered in BTL4MethodDescription[].
VERIFIED LIVE (BT_SECTOR_LOG): Make port=1 pos=(125,579) image=helv15.pcc gridCached=1;
Execute -Z=960.4 X=361.6 -> sectorA=510 sectorB=504 (Round(9.6)+500=510, Round(3.6)+500=504
-- authentic 100-unit sectors from live mech position). Gauge composite renders full,
no crash. The skip list is now exactly the two remaining widgets (prepEngr x12, messageBoard).
Also: a permanent BT_GAUGE_SKIP_LOG diagnostic (GAUGREND.cpp, gated) that logs each
unregistered gauge primitive the dev-parse skips -- the tool that pinned this down
(earlier "not built" runs were killed before the lazy gauge-renderer init).

Two coupled fixes so the condenser valve gauge (ValveSetting -> coolantFlowScale
@0x15C) reads its authentic value instead of garbage/zero.
STEP 7 (gating dedup): heat.cpp carried STUB Condenser ctor/dtor/TestClass/
TestInstance/CreateStreamedSubsystem that ODR-duplicated the REAL bodies in
heatfamily_reslice.cpp and WON under /FORCE (heat.obj links first) -> the real
ctor (which sets valveState=1) was shadowed, leaving valveState=0xCDCDCDCD.
#if 0'd the heat.cpp stubs so the reslice ctor (@4ae568, byte-verified: valveState=1,
coolantFlowScale=0, massScale=refrigerationFactor, condenserNumber from name) is the
sole definition. DefaultData/GetClassDerivations/ResetToInitialState (not duplicated)
stay in heat.cpp.
STEP 9 (the real writer): FinishConstruction() at the Mech ctor tail was a no-op
template stub in place of FUN_0049f788 = RecomputeCondenserValves -> coolantFlowScale
was never written (stayed 0). Reconstructed it (byte-verified vs part_012.c:9264):
distribute coolant flow across the mech's condensers, coolantFlowScale_i =
valveState_i / sum(valveState), with the condenserAlarm@0x1DC change pulse
(2-if-flow<=old-else-1, then 0). Walks the populated subsystem roster filtering
Condensers via IsDerivedFrom (behaviorally identical to the binary's @mech+0x7cc
condenser chain, GUID 0x50e4fc). Wired as BTRecomputeCondenserValves(this) at the
Mech ctor post-init pass (binary @9457). _DAT_0049f850 fallback confirmed 0.0f (PE read).
Verified: [valve] the Blackhawk's 6 condensers each read flow=0.166667 (=1/6, total=6)
for both player + spawned enemy, no every-mech crash; combat TARGET DESTROYED,
un-regressed. Diagnostic BT_VALVE_LOG added.

The 0xBBE heat-sink BANK was built as a plain HeatSink, so the numeric-R
cockpit gauge binding HeatSink/AmbientTemperature (L4GAUGE.CFG:4552) had
no publisher -> the LAST unresolved config attribute.
Reconstruct AggregateHeatSink : HeatSink (ctor @4ae8d0, own GUID 0x50e590),
byte-exact + static_assert-locked (heatSinkCount@0x1D0, ambientTemperature
@0x1D4=300, helper@0x1D8 0xC link node, sizeof 0x1E4 == factory alloc @9993).
Publish HeatSinkCount + AmbientTemperature via a dense-prefix attribute table
chained to HeatSink::NextAttributeID (shared HeatSink table unchanged, so
CoolantMass/CoolantCapacity keep resolving). Move CreateHeatSinkBankSubsystem
into heatfamily_reslice.cpp (needs the class def) and build the real class at
factory case 0xBBE; mech.cpp unchanged.
DELIBERATE DEVIATION (documented in the class): keep the base HeatSinkSimulation
the HeatSink ctor installs; do NOT reimplement the authentic Performance @4ae73c
-- it derefs a raw self+0xE0 -> [+0x158] that does not map in our compiled layout
(AV/NaN, and runs for EVERY mech), and ambientTemperature is a frozen constant so
the gauge reads 300 either way. Authentic relaxation model deferred.
Verified: [attr] HeatSink/AmbientTemperature OK; all 50 config attribute
bindings resolve (0 NULL); no every-mech crash; combat TARGET DESTROYED,
FIRED #41+, un-regressed.
