The playtest report (sound plays, no gauge drop, no cloud) traced to the
Reservoir's InjectCoolant chain being dead in three places:
- The handler was never REGISTERED: the binary's Reservoir handler table
@0x50e680 has one entry {4, "InjectCoolant", @4aee70}; added
Reservoir::GetMessageHandlers + the press/release handler (press starts
the flush gated on coolantLevel@0x12C > 0 -- the old body misread +0x12C
as currentTemperature; release stops it; novice lockout via FUN_004ac9c8).
- Reservoir::InjectCoolant (@4aefa4, 1019 bytes) was an empty stub -- the
drain the coolant gauge reads. Reconstructed in full: work list =
condenser/weapon/heatable chains (+0x7cc/+0x7bc/+0x7ac, roster-walk
emulation with the binary's duplicate-visit weighting; HeatSink-filtered
[T2 guarded]) + the linked master sink; per sink with flowScale != 0 move
squirtMass x flowScale x dt (clamped to the tank / sink capacity) and
credit pendingHeat with the negative carried-heat delta capped at
sinkMass x reservoir startingTemperature -- the set%-biased flush of the
manual (p24), riding the existing heat model.
- Two latent ctor decode bugs surfaced and fixed: the master gate @4af408
(and @4aeb40 HeatWatcher, swept) reads the OWNER MECH's simulationFlags
(*(param_2+0x28)), not the resource's subsystemFlags (the misread left
the CoolantSimulation Performance unregistered); and the capacity scale
FILDs the bank's INTEGER HeatSinkCount ((float10)*(int*)(link+0x1d0)) --
the float reinterpret gave ~1e-44 -> a permanently empty tank.
Capacity = 0.05 x heatSinkCount x streamed CoolantCapacity (BLH: 6.0).
Visual: the binary's mode-1 coolant-effect renderable (FUN_00456a68, built
for classID 0xBC0 on "ReservoirState", part_014.c:5439; tick @part_007.c:
8780) starts psfx 19 = FLUSH.PFX ("Coolant flush", BTDPL.INI) when the
state changes to 1 -- BTSpawnFlushCloud (mech4.cpp) spawns it on the same
alarm edge as an attached emitter at torso height.
Input: new CONTROLS.MAP action "Flush" on 'H' (HELD; press+release both
dispatch, the held-button payload). Diags: BT_FLUSH_LOG, BT_FLUSH_TEST.
Verified live (FOGDAY): [flush] Reservoir level 6 -> 0.13 -> 0 over ~0.6 s
held (= the manual's 3-4 punches to empty), the coolant vertBar source
Reservoir/CoolantMass drains, and the bluish condensation cloud rises from
the mech (scratchpad/flush_cloud.png vs flush_before.png).
