return-0 stub; the Reservoir BAR now drops when a damaged mech leaks
The user watched the coolant panel's level bar during the leak bench and it
never moved -- correctly: a leaking subsystem drained only its own loop,
because the slot-14 top-up (DrawCoolant) was stubbed. Disassembled the real
base @0x4add00: the draw RECURSES UP the sink linkage, scaling by
coolantFlowScale@0x15C per hop, terminating at the Reservoir's supply
(@0x4af3b0 -- clamp to [0, coolantLevel], drain the tank, return granted --
already faithfully ported as Reservoir::DrawCoolant). The binary's terminal
hop is the bank's slot-14 override @0x4ae8b0 resolving its reservoir
connection @0x1D8 (the port's 'helper' member -- not vestigial after all);
the port's existing Reservoir-ctor Attach + Reservoir override terminate the
same chain equivalently (the extra bank hop scales by ctor-default 1.0).
Implemented the base recursion (null-guarded -- the binary calls through the
resolved link unguarded; authored topology always links) + a BT_COOL_LOG
[resdraw] probe at the supply.
Verified live: a destroyed myomer's damage leak pulled the central tank
6.0 -> 5.58 over ~30s ([resdraw] granted lines) -- Reservoir/CoolantMass,
the cockpit coolant bar, now visibly drops as a damaged mech bleeds
coolant, and DeathReset refills it on respawn.
