BT_FORCE_TORSO sweeps the twist BUTTONS -- the members the streamed direct
mappings write -- so the chain runs without a hand on the RIO. Live on the
pod: twist sweeps -0.015 to -0.891 rad and back as cmdL/cmdR alternate, at
the resource rate 0.873 rad/s, inside the authored +/-2.443 limits, with
jointtorso resolved. End to end: attribute id -> direct-mapping destination
-> TorsoSimulation integrator -> skeleton joint -> the canopy eye hanging off
that chain. 5.3.68's table and 5.3.71's integrator both confirmed against
real button semantics.
Two buffer overruns, one of them mine. Reading TORSO.CPP back caught the
ctor still zeroing dynamicsState[22] after I shrank the array to [16] by
carving the command members out of its front: 24 bytes past the end of every
Torso, on the heap, every mission, since 5.3.68. A sweep for the same shape
across BT/BT_L4/MUNGA found a pre-existing one -- MECHMPPR.CPP zeroing
reserved[22] against reserved[21].
Both now bound by ELEMENTS(). The rule for this tree: any array carved out
of a reserve block must have its initialiser bound by ELEMENTS, because the
carve is exactly the edit that silently invalidates a literal.
Neither explains the residual host fault (it predates 5.3.68 at 3/3), but
both were real corruption running in every mission -- and the Torso one was
introduced by the very fix that cut the fault rate, which is worth
remembering whenever a rate MOVES instead of going to zero.

TorsoSimulation now carries the donor's digital command handling (binary
@004b5cf0): elevate up/down, twist left/right with limit clamps, the
centre-button recenter latch slewing home across frames, and the ramp
machinery kept verbatim including the binary's punchline -- the shipped build
unconditionally overwrites the ramp with 1.0f, authored dead weight preserved
as the binary's shape. recenterActive carved from the dynamicsState reserve.
With 5.3.68's table fix the RIO/TM twist buttons land in these members and
move the torso, and the canopy eye rides the twist chain.
Also corrected in the roadmap: the 5.3.70 TriggerState 'wart' was not a wart
-- CheckFireEdge already compares fireImpulse's bit pattern as a signed int,
sign-correct for button ints and floats alike, and the donor binds and types
the member identically.
Fault rate, measured: riostreak.sh ran four consecutive vRIO-live runs --
CLEAN/CLEAN/FAULT/CLEAN, faults only ever in the load window (ticks 42-53k),
clean runs always past launch. Post-fix tally 8 runs / 2 faults (~25%; was
3/3 before the Torso fix). Our load window is ~60s where shipped's is ~15s:
if the residual is a constant-rate hazard during load, shipped's expected
per-run rate is only ~7% -- 'shipped survives' may be exposure luck, and the
residual is most likely an emulator-fork serial/DPMI interaction rather than
a game defect. Next probe: hook the fork's page-fault path on the fixed cr2
and dump recent serial-IRQ deliveries + guest cs:ip history, plus a
shipped-exe streak for the baseline.

The [map] audit named it in one run: subsystem 17 = Torso, attribute ids 12/13
unresolved. The donor's decompiled torso.hpp carries the authentic enum with
binary offsets -- ids 3..15, including StickPosition(9), TorsoUp/Down/
Left/Right(10-13), TorsoCenter(14), MotionState(15). Our table stopped at
seven entries with MotionState at id 9, on the strength of a comment claiming
the rest were messages.
The streamed control mappings bind BY ID as direct WRITE destinations, so the
truncation produced two different crashes from one cause: in TM mode the
button ids 12/13 resolved NULL (the boot write-fault the moment the joystick
polled), and in RIO mode the analog id 9 resolved to our motionState
StateIndicator -- every analog packet from a live vRIO wrote raw floats over a
watcher-socketed object, and the corrupted chains walked into unmapped memory
~30-40s later. That was the 'intermittent' pod fault at the fixed DPMI-host
address. vRIO down = no analog = no corruption, which is why the norio conf
launched: every observation from the whole hunt drops out of this mechanism.
Fix: the full 13-entry donor table; five int command members carved from the
dynamicsState reserve (class size unchanged); ctor zeros them.
Verified, two agreeing runs each way: TM mode launches with a clean audit and
the Thrustmaster joystick driving the torso (stickY=0.907 -> torsoElev 0.349);
RIO mode with vRIO STREAMING launches, zero faults, weapons cycling.
pod_render_rec is no longer poisoned and the norio workaround is obsolete.
The audit-before-the-archive-call pattern (BT_MAP_LOG walks the same streamed
table CreateStreamedMappings consumes, naming what will not resolve) turned a
two-day intermittent-corruption hunt into a one-run lookup. The streamed RES
tables are binding contracts on our attribute enums.

Ladder rungs, each run-verified on the pod rig: ReportLeak (HeatSink),
GeneratorOn (Generator -- member existed, publication missing),
ConfigureActivePress (MechSubsystem -- likewise), AmmoState +
FireCountdownStarted + the rest of the AmmoBin table.
THE PINNED RANGE IS NOW THE AUTHENTIC SHAPE. Publishing ReportLeak on
HeatSink and ConfigureActivePress on MechSubsystem shifts the chain down two,
and MechWeapon's bridge to its binary-pinned PercentDone (0x12) collapses
from THREE guessed pads to ONE -- which is exactly the arithmetic the shipped
string pool predicts (MechSubsystem 1, HeatableSubsystem 3, HeatSink 6,
PoweredSubsystem 5). Three pads of guesswork replaced by a real attribute
and a real base-class row. HeatableSubsystem and Torso rebase onto
MechSubsystem::AttributeIndex; MechControlsMapper does not (it derives from
Subsystem directly).
Types were chosen deliberately this time, per the AudioWatcher families the
engine instantiates (Motion / Hinge / Scalar / StateIndicator): every *State
name resolves to a StateIndicator, ReportLeak is a Scalar.
RESULT: the pod run now gets past every authored watcher and DRAWS THE FULL
COCKPIT -- sensor cluster, myomers, cooling, the weapon panels, kills/deaths
-- with the board booted and audio running. It then exits without flushing
its redirected stdout, so the exit reason is not yet known; next step is a
run with the redirect removed so the console is readable.

The linker map named the faulting function: the crash address minus the CODE
base (0x410000) looked up in btl4opt.map's Publics-by-Value landed inside
AudioStateWatcher::AudioStateWatcher +0x2D.
AudioStateWatcher is AudioWatcherOf<StateIndicator> and its ctor immediately
runs Cast_Object(StateIndicator*, attributePointer)->AddAudioWatcher(this).
So every authored *State name must be published as a StateIndicator --
AlarmIndicator counts, it derives from one -- and pointing one at a plain int
sends that member call through garbage.
That explains both earlier failures: the AlarmIndicator attempt was the right
type but was tested with other bugs still in the batch, and the plain-int
attempt was simply the wrong type and crashed further along.
Published as state objects: Reservoir/ReservoirState -> reservoirAlarm,
Generator/GeneratorState -> stateAlarm, plus new StateIndicator members for
Condenser/CondenserState and Torso/MotionState. StateIndicator has no
Initialize(); the default ctor suffices because the watcher only needs the
object to exist.
Verified on the pod rig: no crash, ladder advanced to ReportLeak.
Technique worth keeping: on an extender fault, subtract 0x410000 from the
dumped address and look it up in btl4opt.map -- it names the engine function,
and for this family of work that names the watcher class and hence the
required member type.

BTL4.RES stores each watcher as a (SUBSYSTEM, ATTRIBUTE) string pair, so the
complete list can be extracted directly instead of discovering one name per
6-minute run. Banked the extraction method and the full normalised table.
Sixth rung climbed: Torso/MotionState (staged member, appended at the end of
Torso's own range so no downstream id moves). LocalVelocity and
LocalAcceleration turn out to need nothing -- the engine's Mover already
publishes them.
Also banked, and deliberately NOT acted on: ReportLeak and
ConfigureActivePress are base-class attributes inside the pinned range, and
chasing them turned up what looks like the authentic attribute layout. The
shipped pool gives MechSubsystem 1, HeatableSubsystem 3, HeatSink 6,
PoweredSubsystem 5 -- which counted from Subsystem::NextAttributeID=2 lands
MechWeapon's real ids on the binary-pinned 0x12 with EXACTLY ONE pad, where
our tree needs three. That arithmetic is strong evidence for the original
layout, and reconciling to it would replace three guessed pads with the real
table. But it moves ids underneath a cockpit currently verified at 98.9%
pixel-identical, so it wants a deliberate session with the A/B rig open
rather than a bulk edit at the end of a long one.

Under the documented rig (launch_pod.ps1 with the GL bridge up) the 'couldn't
load object' count went to ZERO. .BGF loading was never a reconstruction
problem, only a missing bridge.
What blocks now is a series of authored AttributeWatchers: BTL4.RES binds
them BY NAME and the engine Fails outright on any that does not resolve, so
each is a name our subsystems must publish. Five rungs climbed, each
run-verified: UnstablePercentage, SpeedEffect (Myomers table), AnimationState
+ CollisionState/CollisionNormal + ReduceButton (Mech), and the full Torso
table (all six authentic names mapped onto existing members).
The method that makes this cheap is banked: the shipped binary's string pool
carries each class's attribute names CONTIGUOUSLY in ID ORDER after the class
name, and in every case so far our member declarations sit in the same order
-- which confirms the layout and lets ids be pinned rather than guessed.
Intersecting those names with BTL4.RES gives the exact work list.
A THIRD miswired SharedData found on the way: Myomers carried Subsystem's
tables where it derives from PoweredSubsystem, the same defect as
MissileLauncher (5.3.33). Worth a sweep across every subsystem.
Staged member TYPES are provisional and documented as such: AttributeWatcherOf
reads *(T*)attributePointer and the instantiation comes from the resource,
which the string pool does not reveal. Nothing drives them yet, so settle the
types with the models that write them.

Reconstructs the shared skeleton-joint resolver and binds the first subsystem
(Torso) to the live skeleton.
- Mech::ResolveJoint(name) (mech.cpp @00424b60): GetSegment(name) -> segment
joint index -> GetJointSubsystem()->GetJoint(idx).
- Verified the JointedMover base streams the full skeleton headlessly:
jointCount=19, 40 named segments (gun joints jointlgun/jointrgun, shoulders,
hip, leg joints jointlthigh..jointrankle). BT_MECH_LOG [skel] summary;
BT_SKEL_DUMP lists every segment/jointIdx.
- Torso resolves + binds its twist joint (ResolveJoint(torsoHorizontalJoint))
and pushes currentTwist onto it via Joint::SetRotation (hinge->Radian,
ball->EulerAngles yaw). The TEST.EGG mech has a fixed torso (horizJoint='',
enabled=0) so its twist path is inert -- correct + guarded, zero Fail.
Next joint piece: elevation -> gun joints (jointlgun/jointrgun, the fixed-torso
aim mechanism) via weapon-joint binding; then gait leg animation. Both are
VISIBLE only under the renderer; headlessly the joint transforms are loggable.

Reconstructs Torso::TorsoSimulation (installed as the Torso's per-frame
Performance) and wires the torso aim into MechControlsMapper::InterpretControls,
so the control surface now covers aiming as well as locomotion.
- TORSO: analogElevationAxis/analogTwistAxis + SetAnalog* setters,
CurrentElevation()/GetHorizontalEnabled() accessors. TorsoSimulation slews
currentElevation += analogElevationAxis*baseElevationRate*dt clamped to the
vertical limits, and (if horizontalEnabled) currentTwist by the twist axis
clamped to the horizontal limits (authentic torso.cpp core; the skeleton-joint
application is deferred with the render wave).
- InterpretControls: routes stick pitch (stick_y, squared) into the torso
elevation every mode; Std/Vet route stick yaw into the twist. BT_FORCE_ELEV
dev hook.
Verified: BT_FORCE_ELEV=0.8 -> the elevation slews up and clamps at the authentic
verticalLimitTop = 0.349 rad = 20deg; neutral -> 0; zero Fail.
Deferred: skeleton-joint application (render wave), HUD free-aim slew,
look/eyepoint commit.
