in the leak chain
HeatSink::UpdateCoolant prices the damage-driven leak from the QUALIFIED
engine member (Subsystem::damageZone @0xE0): coolantDraw = zoneDamage *
heatLoad, with the coolantActive hysteresis (= the ReportLeak attribute
the 19 authored leak watchers ride). But the MechSubsystem ctor only
ever filled its re-declared SHADOW member (gitea #64, gotcha #1), so the
engine member stayed NULL forever, zoneDamage pinned 0, and a coolant
leak was STRUCTURALLY IMPOSSIBLE no matter how much damage landed --
Oracle's night-7 report exactly. The #80 crit fix and the #83 collision
rattle write real subsystem-zone damage, but into an object the leak
reader could never see.
Fix: alias the ENGINE base member to the same zone in both MechSubsystem
ctors. Every shadow reader keeps working (same object); the engine base
Subsystem::TakeDamage latent null-AV (#64 consequence 2) is disarmed;
the full #64 de-shadow sweep remains the long-term cleanup.
Verified live (solo, BT_COOL_LOG/BT_CRIT_LOG): collision rattle drove a
damaged Myomers to [cool] draw = dmg*heatLoad with the level draining;
sustained weapon fire rolled real crits ([critroll]) and produced 588
leak-pricing lines. Authored routing extracted from BTL4.RES: collision
rattle targets HeatSinkBank 0.3 / Gyro 0.35 / Torso 0.25 / Myomers 0.35
(Condenser+Reservoir authored 0 for collisions); weapon crits select via
the zone's crit-entry list. Known-remaining fidelity item (documented):
HeatSink::DrawCoolant (slot 14, central top-up) is still a return-0 TODO.
