Nick ran the cab with the real board and the mission came up on the main view
with every MFD dark -- and not one [glasswin] line in the log.
BTGlassPanels_Create() was called only from the END OF THE PadRIO CONSTRUCTOR.
The panels began as the frames around the on-screen RIO button banks, so "the
buttons ride the device" was reasonable then; it is backwards on a real cab.
L4CONTROLS=RIO:COM1 means PadRIO is never constructed, so the MFD windows were
never created -- silently, since nothing is wrong from the display layer's
point of view.
The panels are a DISPLAY concern. Creation moves to LBE4ControlsManager,
after the L4CONTROLS parse where every device branch converges, and a
symmetric BTGlassPanels_Destroy() goes in its destructor: ~PadRIO tore them
down, ~RIO knows nothing about them, and windows outliving the surfaces they
blit would crash on the next mission cycle. Both calls are idempotent
(Create returns on gWinCount != 0), so the proven PadRIO path is unchanged
and simply arrives first. Both guarded by BT_GLASS -- L4GLASSWIN is only in
the build when the gate is on.
Verified on the cart: hardware RIO up AND all three surfaces on their intended
displays in the same run.

The WIP's 'pose does not hold' was a chain of bench-instrument errors, not a
code bug: every capture ran in COCKPIT view (the pilot cannot see their own
legs; the eye-height residual masked as reversion). Joint probes prove the
park holds indefinitely (knee 1.138, root -2.219 steady); the 2-node bench
shows the observer's replicant fully crouched and held (duckmpA_031 -- the
type-3 state record carries it with zero new replication code); the second
scripted press (new BT_BTNTEST2 env) verifies RISE -> standing zeros.
MP button delivery confirmed mode-mask-clean (the one miss was round-start
jitter). Diags added, all BT_DUCK_LOG-gated: SetLegAnimation re-arm tracer,
1 Hz joint probe, RIO press mode-mask, BT_TREE_LOG topology dump, and the
squat-park log. RESIDUAL filed: pilot's own cockpit eye does not ride the
root drop (DPLEyeRenderable chain composition; cosmetic).

Operator called binary-faithful; the trace agrees. The hook (bfc072b/
fa3d634) fired ALONGSIDE the key's authored per-page function, so on a
weapon eng page an armed pilot pressing UNJAM/EJECT to clear a jam would
self-destruct -- a destructive hijack of a real control. Removed; the
authored press model stands alone: pilot KEYPAD bank (desktop numpad) or
the PANIC key while armed. The flashing engEject cell is the invite lamp.
Regressions: armed PANIC press -> PUNCH-OUT (1); armed soft-key 0x0B press
-> no eject (0); streamed ammo-eject route untouched (the hook was purely
additive).
Remaining marked deviations, both flagged in code and handoff: the coolant
arm hysteresis (0.05/0.06) and the Panic-button->keypad desktop wire (the
pod's physical matrix emulated).

The absolute-pointer scan missed the E8-relative call; the later byte-scan
found it (FUN_004a9b5c+0x10 -- the master performance evaluates eject
permission per frame in the shipped binary). Under deadline pressure the
disproven 'unfinished/dead code' claim leaked back into three comments and
the handoff; swept per the correction mandate.
Settled press model, now stated correctly everywhere: pilot eject = the
pilot KEYPAD bank while armed (+ the PANIC key reporting through that
matrix). The MFD soft keys NEVER pilot-eject in the binary -- every page
routes them to authored functions; the flashing engEject cell is the
INVITE LAMP. The port's page-gated eng-key eject is a MARKED CONVENIENCE
deviation (operator-requested), and the coolant hysteresis is a MARKED
smoothing deviation for a degenerate boundary oscillation -- not
completions of unfinished code.

The page-gated eject query ran in the window-click thread (PadRIO
EmitButton) and dereferenced the TU-local application global -- NULL there
under the /FORCE duplicate-symbol layout -> c0000005 at mode-manager +0x50
the moment the operator pressed the eng eject key (field crash,
live.log [crash] record). Moved into LBE4ControlsManager::ProcessRIOEvent's
ButtonPressedEvent branch, where mode_mask is already resolved on the game
thread; PadRIO now only queues events. Same gate semantics (armed + that
bank's ENG-page mode bits); verified no-crash + no-eject on the quad page.

Two finds close the press path the operator field-tested:
1. The pod's guarded PANIC key reports through the PILOT KEYPAD bank -- the
binary's ONLY panic press binding is keyboardGroup[KeyboardPilot].Add(
mode 0x200000, mech, 0x19) (FUN_004d266c); there is NO buttonGroup[0x3d]
consumer (0x3d is the lamp address). The desktop Panic click now ALSO
lands as a pilot-keypad key (PadRIO::EmitButton -> EmitKeypad), so the
armed-mode binding fires; a healthy press stays a mode-masked no-op,
exactly the pod behaviour.
2. KeypressMessageID resolved to 0x17 via enum-chain arithmetic; the binary
passes LITERAL 0x19 (two mapper ids are unreconstructed). The armed
keypad send arrived at the Mech as msg 0x17 -- no handler, silently
swallowed. Pinned to 0x19 (Mech::EjectPilot's id on the OWNER receiver --
the collision is the design).
Verified headless through the REAL click seam (BT_BTNTEST=61): generators
killed -> panic-arm ON -> screen-click Panic -> [lbe4key] unit 0 mode
0x650421 -> PUNCH-OUT. Also: IsDisabled eject refusals now log; [padkey]/
[lbe4key] seam tracing under BT_PAD_LOG.
Still open (cosmetic): the flashing eject slot on the engineering MFD shows
no graphic -- the streamed page element's pixmap is unreconstructed.

NotifyOfDisplayModeChange override (vtbl+0x4C @4d1ae4) + wire desktop 'N'
The secondary screen's schematic selector was mislabeled: @004d1ae4 (the
bits-18..20 ModeSecondary* mask swap) was reconstructed as a non-virtual
"SetControlMode" that nothing called, so the desktop stayed pinned on the
Damage view. The binary's L4 vtable @0051e440 pins the truth:
+0x48 = @004d1acc <- CycleControlModeMessageHandler (FUN_004afbe0):
forwards to the base RET no-op @004b048c. A BAS/MID/ADV
control-mode change never touches the secondary view
(empirically confirmed: BT_MODECYCLE_TEST cycles the CONTROL
MODE lamp, mask bits 18-20 unchanged, schematic stays ARMOR).
+0x4C = @004d1ae4 <- CycleDisplayModeMessageHandler (FUN_004afcac):
THE Damage/Critical/Heat selector, indexed by displayMode
(table @0051dbe4 = ModeSecondaryDamage/Critical/Heat).
Authentic pod inputs (streamed type-6 .CTL EventMappings, dumped via the
new BT_CTRLMAP_LOG EVENT records): secondary-panel button 0x15 -> msg
0x15 CycleDisplayMode (manual p13, the "'Mech status Info center" bottom
left of the secondary screen), button 0x18 -> msg 0x14 CycleControlMode
(manual p6, top right), 0x10/0x11 -> ZoomIn/Out. The DOS keyboard
fallbacks (Keypress 0x13d/0x13e = extended F3/F4) are dead under the
WinTesla VK map, hence the desktop pin.
Port wiring (the M/ModeCycle pattern): key N / pad RightThumb -> action
DisplayCycle -> gBTDisplayCycle -> CycleDisplayModeNow() -- the same body
the pod console button message drives. Both .MAP profiles + the
compiled-in default updated.
Verified live (docked gauges + BT_SHOT, BT_VIEWCYCLE_TEST): the sec
panel cycles ARMOR DAMAGE silhouette -> CRITICAL DAMAGE subsystem list
-> HEAT DAMAGE colored list, mask 0x450421 -> 0x490421 -> 0x510421; M
control-mode cycling un-regressed (BAS/MID/ADV lamp cycles, view pinned).
Diags: BT_MODE_LOG, BT_VIEWCYCLE_TEST=<frame>, BT_MODECYCLE_TEST=<frame>,
BT_CTRLMAP_LOG now dumps EVENT records. KB: gauges-hud secondary-view
section rewritten, CLASSMAP +0x48/+0x4C slots, decomp-reference env
gates, GAUGE_COMPOSITE phase-4 entry resolved.

User-reported: glass left/right inverted. Closed with live sign algebra:
the joystick-group wire push was traced end to end (new env-gated
BT_CTRLMAP_LOG push trace + record mode-mask in the install log) --
measured wire stickX=-1 -> turnDemand=-1, the SAME demand the
user-verified dev D-key-RIGHT produces (stickX=+1 -> turnDemand=-1 via the
bridge's negate-once, cb82d8c). The mapper interprets the authentic RIO
WIRE convention: stick right = NEGATIVE JoystickX (the vRIO/RIOJoy
calibration convention). PadRIO now publishes X negated (all sources --
keyboard deflect, pad LX, panel -- uniformly); Y stays screen-sign;
L4PADFLIP still flips both. Also: PadRIO honors BT_KEY_NOFOCUS=1 (the
btinput harness override) for automation.

33 master commits in (relay TCP/UDP + PySide6 operator console, CONTROLS.MAP
+XInput binding engine, camera seats, torso pitch aim, sign fixes, the 1995
manual, version stamping, 18-mech certification). Conflicts: .gitignore +
CLAUDE.md router rows (combined).
SEMANTIC RECONCILIATION (the one real overlap): masters btinput binding
engine (ungated, CONTROLS.MAP) and the glass PadRIO (gated, bindings.txt)
would both read the keyboard/pad in a glass+PAD session. btinput now joins
the stand-down convention: BTInputPoll yields (and BTInputSuppressKey claims
NOTHING, so authentic hotkeys flow) when an operational cockpit device owns
the input path -- BTRIODevicePresent, BT_KEY_BRIDGE force-override honored,
forced harness exempt. One input system per mode: btinput on pod/dev
desktops, PadRIO on glass. The mechmppr/mech4 bridge merges composed clean
(masters negate-once sign fix inside our device-gated bridge). The D1 relay
keeps its own raw sockets by design (an alternative LAN wire; Steam and
relay are separate modes).
Verified post-merge: all 3 configs build; glass boots with [input] binding
engine standing down + PadRIO owning input (30 ticks); pod forced-walk
speedDemand=61.501 with btinput ACTIVE; 2-node loopback MP full 31/31
mission, 76/76 ticks.

The pod's controls reach the game through the RIO serial board; on a
desktop that hardware is a keyboard shim of hardcoded GetAsyncKeyState
reads. New binding engine (game/reconstructed/btinput.cpp) maps PC keys
and an XInput pad onto the authentic channels through a user-editable
file (content/CONTROLS.MAP, community-suggested grammar, corrected):
key/pad -> button <addr> real buttonGroup emissions, mirroring the
RIO convention exactly (press a+1 w/ mode
mask saved, release -a-1 w/ saved mask;
L4CTRL.cpp:2470-2520) -- aux/preset banks,
hotbox, panic, reverse thrust all reachable
key/pad -> axis Throttle rate (lever), pedals/JoystickX
deflect (turn/twist) into the existing
virtual-controls integrators (feel, gait
detent, spring-centering all unchanged)
keypad pilot|external <n> keyboardGroup key values ('0'-'F')
pckey <char> any authentic 1995 typed hotkey
action <name> port dev controls (view, all-stop, ...)
Keys claimed by a binding are SUPPRESSED from the legacy WM_CHAR/KEYUP
feed -- ends the historic double-dispatch ('w' drove AND selected pilot
0; F5's key-up value 0x74 aliased to the 't' hotkey; letter key-ups fed
the developer fake-event dispatcher). Unbound keys keep their authentic
meaning. The dual-use 'V' is split: V = view toggle, B = look behind.
Default profile = WASD classic (compiled-in twin; delete the file to
restore). CONTROLS_NUMPAD.MAP ships the corrected community layout
(keypads are NOT buttons 0x50-0x6F -- that space doesn't exist; no
clickable cockpit exists so everything needs a binding; keyboard fire
buttons added; 0x36/0x37 are hotbox not 'config'; missiles moved off
Ctrl). XInput loads dynamically (1_4 -> 9_1_0), disconnected-pad
probing rate-limited; pad sticks write the axes as absolute positions
(the spring is physical), triggers/buttons per the file.
Verified live: bindings load (43), W and NumPad8 drive (speedDemand 0 ->
61.5), X all-stop (spd -> 0), aux-bank emission (D1 -> [input] 0x2f
PRESS/release under the numpad profile), suppression both directions
(posted 'r' reaches [keych], posted 'w' swallowed), full-keyspace
WM_CHAR+WM_KEYUP fuzz x3 survived with sim advancing, XInput graceful
with no pad, 2-node relay session un-regressed (full ladder + UDP).
Pad-in-hand testing still needs a physical controller.

New engine query BTRIODevicePresent() (L4CTRL.cpp, ungated -- pod-correct for
the serial RIO too): device exists AND IsOperational(). Both dev input
bridges -- the mech4.cpp mapper-attr writes and the mechmppr.cpp BT_KEY_BRIDGE
block -- now gate their WRITES on it: BT_KEY_BRIDGE unset = auto (bridge only
when no device), 0 = force off (the documented pod setting, honored), else
force on. The BT_FORCE_THROTTLE headless harness always rides the bridge.
The mapper demand READ (turn = turnDemand) always runs.
Verified live (glass build, PAD): OS-injected LSHIFT hold slews the PadRIO
throttle 0 -> 0.33 -> 1.0 with pre==thr every frame -- the value arrives via
the ENGINE push through the streamed .CTL binding, not the bridge -- and
speedDemand=61.501 comes out of the authentic InterpretControls.

L4RIO.h splits the abstract cockpit-control surface (RIOBase: enums, the five
analog Scalars, GetNextEvent/SetLamp, no-op serial ops, NEW IsOperational) out
of the serial RIO (RIO : PCSerialPacket, RIOBase -- byte-for-byte behavior kept,
ctor assigns as before); LBE4ControlsManager holds a RIOBase* and gains the
gated L4CONTROLS=PAD factory arm (BT_GLASS; OFF build logs+ignores the token).
NEW gated TUs: L4PADRIO (XInput+keyboard synthesize the surface; 3s hot-plug
re-probe; focus-guarded keys; per-poll AnalogEvent heartbeat; lampState[] +
static SetScreenButton/GetLampState for the panel) and L4PADBINDINGS
(content\bindings.txt profile, self-documenting default written on first run;
deflect/slew/set axis model; addresses validated against ButtonCount).
Verified live (glass build, L4CONTROLS=PAD): bindings written+parsed 44/10/5,
XInput pad detected, 121 streamed mappings install via stock PrimaryRIO path,
2157 frames clean. Pod build (gates OFF) compiles the split with zero
behavioral delta.

The streamed L4 mapping resource carries the binary's positional attribute ids
(stick=3, throttle=4) but MechControlsMapper chained from Subsystem::NextAttributeID
== 2 -- every streamed record resolved ONE MEMBER LATE (attr 4 -> pedalsPosition,
verified via the new permanent BT_CTRLMAP_LOG diagnostic in CreateStreamedMappings).
A latent real-pod bug: the serial RIO throttle would drive the pedals member; the
dev keyboard bridge masked it. Fix per the mechweap/mech attrPad idiom: ids pinned
to the binary numbering, id-2 gap padded, static_assert-locked. Torso + weapon
chains verified already aligned. Regression: BT_FORCE_THROTTLE headless walk clean
(speedDemand=61.501 through authentic InterpretControls, gait cycles, no faults).

PLATFORM PROFILE (-platform pod|dev / BT_PLATFORM / run.cmd pod; default dev):
an env-preset selector, NOT a code fork -- it picks which environment the
existing video/gauge/input code reads. dev = single 800x600 window + keyboard
(the working build); pod = RIO input + (on real hardware) the multi-surface
gauges/MFDs, mirroring content/SETENV.BAT (the pod path -- FindBestAdapterIndices
/ SVGA16 -- is left untouched). The multi-surface needs the pod's 2 video cards,
so -platform pod does NOT auto-enable L4GAUGE on a dev box (stays bootable,
single-window). Also fixes a real engine bug: SVGA16::BuildWindows
PostQuitMessage'd on a CreateDevice failure but fell through to a null-device
deref (segfault) -- now breaks (inert on the pod).
GAUGE DEV-COMPOSITE, Milestone A (option B; opt-in BT_DEV_GAUGES, default OFF):
wake the (dormant) gauge renderer so its CPU-rastered pixelBuffer can later be
composited into the dev window, WITHOUT touching the pod SVGA16 output path.
SVGA16 does no per-surface D3D in this mode (a DevGaugeComposite() gate forces
the no-surface path + short-circuits Update/Refresh). Waking the never-exercised
gauge subsystem exposed 4 latent reconstruction bugs, each guarded:
SVGA16::Update / Refresh (empty mSurfaces[]), LBE4ControlsManager::MakeLinkedLamp
(NULL lamp manager), L4GaugeRenderer::NotifyOfNewInterestingEntity (garbage
warehouse chain). It now boots STABLY; the gauge reconstruction is incomplete
(shadowed lamp-manager + warehouse members) -- Milestone B (the composite pass)
will reveal whether the content is real. See docs/GAUGE_COMPOSITE.md.
Verified: default DEV un-regressed (combat DESTROYED, 0 crashes); pod path
untouched; BT_DEV_GAUGES boots stable.

Clean, self-contained extraction of the BattleTech-specific work from the
reverse-engineering workspace -- engine + game + content + build, with nothing
from Red Planet or the raw archive dumps. Builds green (Win32) and runs the
single-player drive->animate->target->fire->damage->destroy loop out of the box.
Layout:
engine/ MUNGA + MUNGA_L4 shared 2007 engine, carrying our BT render/loader
work (bgfload/L4D3D/L4VIDEO: BSL bit-slice decode, LOD/ground/shadow
models) + image codec; the minimal rp/ headers the audio HAL needs
game/ reconstructed BT logic + surviving-original BT source + fwd shims
+ WinMain launcher
content/ full runtime tree (BTL4.RES, VIDEO/, GAUGE/, AUDIO/, eggs, BTDPL.INI)
docs/ format specs + reconstruction ledgers
reference/ raw Ghidra pseudocode (recon source-of-truth) + decomp exporter
tools/ MP console emulator + map/resource scanners
One top-level CMake builds munga_engine lib + bt410_l4 game lib + btl4.exe.
All paths relativized (186 fwd shims + ~437 CMake abs paths -> repo-relative);
DXSDK is the one external, overridable via -DDXSDK. Verified: builds to a
byte-identical 2.27MB exe and runs combat (TARGET DESTROYED, 0 crashes) against
the bundled content.
