Torso: the TWIST goes LIVE -- electrical watchdog chain, centered crosshair, coherent controls (task #57/#58)
The MadCat torso twists, the view turns with it, and targeting follows. Three reconstruction fronts closed: THE ELECTRICAL WATCHDOG CHAIN (why the torso never powered up): - PowerWatcher::UpdateWatch reconstructed (@004b181c, the REAL registered Performance -- PTR @0050f5fc; Ghidra missed the fn start): the watchdog MIRRORS the watched subsystem's electrical level (+0x278), brownout downgrade when gen output <= minVoltage% x rated. @004b1804 relabeled ResetToInitialState (slot 10) -- the old "Simulation" tag was wrong. - The factory watcher-CONNECT pass reconstructed (vtable slot +0x38, @004aee2c/@004b1a40 byte-identical, recovered from raw exe bytes): watchedLink.Add(roster[watchedSubsystem]) on the master node. Was the SubProxy::Start() no-op -- every watchdog sat at 0 forever. - MinVoltageScale = 0.01 (a 10-byte x87 literal @0x4b1924; was 1.0f = permanent brownout) and PowerWatcher's Derivation chains its REAL base HeatWatcher (the HeatableSubsystem stand-in broke IsDerivedFrom for the whole Torso/Searchlight/ThermalSight family). - KB correction swept: derivation tag 0x50e604 = HEATWATCHER (not "HeatSink"); the btl4gaug heat-widget gate now tests it via the BTIsHeatWatcher bridge. THE CROSSHAIR (task #58 forensics, 6-agent workflow + live probes): - The VIEW is TORSO-MOUNTED: jointtorso -> jointeye -> siteeyepoint in every twist-capable .SKL; the camera + canopy ride the same hinge subtree through HingeRenderable's live matrix-stack compose -- ALREADY WORKING in the port. The crosshair stays screen-centered (center IS the boresight); the twist reads on the tape carets/compass/radar. - The real bug was the port's gBTAimX = tan(twist) slew (the falsified "body-mounted view" model): the camera already carried the twist, so the crosshair counter-slid to hull-forward and the fire ray with it. Deleted; the pick ray inherits the twist from the yawing eye basis. - Two instrumentation traps documented (chase-eye-as-default-camera, BT_FORCE_TORSO clobbering real joints -> the hook now only fills unresolved ones); an over-correcting explicit eye compose was added on those false readings and retired the same day. CONTROLS + REPLICATION: - Q/E spring-center on release (the axis is a twist-RATE demand; the old hold-deflection model drifted forever); X also zeroes the axis and pulses the authentic torso Recenter (@004b6918). M cycles control mode via the real CycleControlMode body. - Torso update-record DIRECTION fixed: engine truth is Write=serialize / Read=apply; @004b6a78 is the READ (was mislabeled Write) and the missing WRITE @004b6a1c recovered from raw disasm (recordLength 0x1C, twist/vel/rate at +0x10/14/18) -- kills the replicant's 0xCDCDCDCD -140-degree ghost twist. - Marching-ghost desync: 4 Standing-case guards zero stale reverse cycleSpeed (negative cadence passed the <= ZeroSpeed stop gate). - Kill credit rerouted to the OBSERVED killer (lastInflictingID -> killer's player link) -- kills count, target K/D populates. KB: subsystems.md (watcher chain), multiplayer.md (record direction), combat-damage.md + gauges-hud.md + cockpit-view.md (torso-mounted view re-correction), decomp-reference.md (new addresses + tag fix), open-questions.md (dead capability-roster loops 2-4, snapshot CD read).
