MP live-play wave: collision economy, missiles, radar transform, panel polarity, comm ticker

The interactive 2-node playtest wave -- every fix decomp-grounded and live-verified:

COLLISION ECONOMY (the ram one-shot): StaticBounce mutates worldLinearVelocity
per contact and ProcessCollisionList walks EVERY touched solid per frame; with
2007 terrain-as-solids the reflections compounded x4-x40 within one frame and a
walking bump one-shot a pristine mech for 112,375 pts (62-pt authentic economy).
Fix: frameEntryWorldVelocity restore per contact (damage always priced at the
real approach speed -- all the binary's physics ever saw); Mech::Reset zeroes
the mover motion (respawn = teleport); [collide-tx]/[mp-hdlr] telemetry.
Gotcha #16 (engine-facility drift class).

MISSILES: peer-visible salvos (the launcher record extension carries a salvo
counter + aim point; ForceUpdate actually enqueues it -- the dirty flag alone
never serialized), the authentic arc (authored MuzzleVelocity vector + the
Seeker's 200m/0.1/300 loft + gain-4 steering, decoded from @004beae4/@004bef78),
world-impact bursts (rounds detonate on cave geometry instead of phasing
through), contact-only damage (flight-cap expiry = fizzle, no more teleport
damage), live re-lead, and ballistic (unguided) shells for autocannons.
projweap's stale BTPushProjectile extern (the /FORCE signature trap, gotcha #6
corollary) crashed the Avatar's first AFC100 shot -- fixed + sweep rule recorded.

RADAR: two transcription bugs made the scope permanently empty -- FUN_0040b244
is the affine INVERSE (not a copy) and FUN_0040adec writes ONLY the 3x3 rotation
(never the translation); worldToView now Invert(view) built rotation-first.
CulturalIcons sorted out of the moving grid (the phantom red pips were map
props), visible-radius culls on all three draw passes, live pip verified at
|delta| x ppm px.  Gotcha #17 (verify the FUN_ body, not its call shape).

WEAPON PANELS (the frozen-dial hunt): the binary's *(subsystem+0x40) means
FAILED -- the recon's 'operating' name was backwards, inverting the destroyed-X
lamps, the panel look, the children enable and the ready-lamp gate (which had
NEVER executed).  Polarity chain corrected end-to-end (failedState, fed by real
damage saturation).  Root cause of the freezes: MFD page-mode gating -- the dev
composite shows ALL pages at once, so off-page dials legitimately stopped; under
BT_DEV_GAUGES the 15 page-plane bits stay active (the exclusive secondary trio
untouched).  The SEH gauge guard now names its kills; repaint-heal resets the
incremental arc after panel repaints; [panel]/[arc] probes added.

COMM/SCORE: MessageBoard LIVE (the engine already shipped the whole
Player__StatusMessage queue; wired the binary's one producer -- the kill branch,
victim's name, 6s -- plus the consumer bridge and a lazy source bind); MP DEATHS
counted via the observed-death tally (each node scores every pilot from locally
observed events, the same model as the KILLS credit) and the -2/-1 engine seed
clamped for display.

DEV UX: node-tagged window titles (-net port), gauge panel reworked (1320x480,
true 4:3 MFD cells, the portrait secondary UNROTATED upright, linear filtering,
BT_GAUGE_SCALE), fixed close spawns via BT_SPAWN_XZ, Boreas flies an Avatar
(first second-chassis live outing).

gauges: secondary/radar MFD composites live on a dev box (Milestone B)

The pod's secondary/radar cockpit surface now renders as an inset in the
800x600 dev window under BT_DEV_GAUGES: radar/tactical grid, SPEED/HEADING/
MAGNETIC/PROP dials, and the color-coded ARMOR DAMAGE mech schematic -- real
gauge content (nzSec=27247), composited from the shared CPU pixelBuffer.

Composite pass (engine): SVGA16::DrawDevInset palette-expands the secondary
plane into a MANAGED texture on the MAIN device and draws an XYZRHW inset quad;
BTDrawGaugeInset() reaches the gauge renderer's 'sec' port and is called from
DPLRenderer::ExecuteImplementation as the last draw before EndScene.

Three reconstruction bugs fixed to get real content:
1. BTL4Application::MakeGaugeRenderer signature mismatch (REAL fix): the
   reconstructed no-arg override only HID the 2007-engine's widened 3-arg
   virtual MakeGaugeRenderer(int*,int*,int*), so the engine built a base
   L4GaugeRenderer whose ctor never parsed gauge/l4gauge.cfg -> empty symbol
   table -> "undefined label 'bhk1Init'" -> no ports/gauges. Matched the 3-arg
   signature so it truly overrides (args ignored; BT is fullscreen). Same bug
   class as the BTL4GaugeRenderer(false,NULL,NULL,NULL) ctor fix.
2. Parse hung on undefined primitives (gated dev accommodation): the BT gauge
   primitive table (BTL4MethodDescription) is still a stub, so an unknown
   primitive -> ReportParsingError -> Fail() -> a MODAL dialog freezing the
   parse. Under BT_DEV_GAUGES, skip the unknown primitive's params so labels
   register and the base "configure" primitive builds the ports.
3. Gauge widgets AV on NULL data bindings (gated): NumericDisplayScalar's NULL
   value_pointer -> GaugeConnectionDirectOf ctor deref (bind NULL->static zero);
   RankAndScore::Execute derefs unreconstructed game state (Gauge::GuardedExecute
   SEH wrapper -> Disable(True) on first fault).

All guards gated on BT_DEV_GAUGES: default DEV un-regressed (TARGET DESTROYED,
0 crashes) and the pod path is byte-unchanged (strict Fail, no guards).

Remaining (docs/GAUGE_COMPOSITE.md): the real gauge WIDGET reconstruction
(BTL4MethodDescription method table + gauge->game-state data bindings), then
Step 2 (RP<->BT MFD port-name reconcile) + Step 3 (2-window layout).

Initial commit: bt411 -- standalone Windows BattleTech (Tesla 4.10 port)

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.
