CydandClaude Opus 5 61563c9efe Glass cockpit refit: one mode resolver, one button geometry, and a cockpit that scales
Replicates the RP412 cockpit line into BT411's own architecture -- porting the
geometry and keeping our renderers, so BT_SHOT single-frame verification stays
intact.

MODE RESOLVER.  Where the secondary displays go was decided in TWO places with
duplicated precedence, and the boot banner read NEITHER -- it announced
"per-display cockpit windows" for every glass boot, surround included.  The
split had also broken BT_COCKPIT=0: documented as the dock-bottom opt-out, the
profile block converted it to BT_GLASS_PANELS=1, so the docked strip was
UNREACHABLE under the glass profile.  One resolver now, consumed by the banner,
the pad-panel decision and the window sizing; BT_GLASS_PANELS is explicit-only;
dock/window modes auto-raise BT_PAD_PANEL so the button field always has a home.

L4RIOBANK -- one button geometry.  Both renderers carried their own copy and had
drifted: an MFD button was 156x138 reaching under the glass in the exploded
window and a 76x24 sliver entirely OUTSIDE the glass in the surround.  One
module owns it now, both are consumers, placement stays per-renderer.  The pod's
under-glass rule (RP412 L4MFDVIEW): reach half the glass in behind the display,
leave a lamp strip clearing the edge, paint buttons first and imagery over --
so the lamp reads as a bar and practically the whole display is the press
target.  The strip scales off the display's SHORT axis (the map is portrait)
with a readable floor.  Retired L4GLASSWIN's three local placers and seven
layout constants.

LAMP FLASH DECODE was wrong [T1].  BTLampBrightnessOf returned max(state1,
state2) and blanked on the alternate phase; RIO::LampState (L4RIO.h [T0]) says
solid shows state 1 and flashing ALTERNATES the two.  Agrees only when one state
is Off -- true for the Panic lamp, which is why it survived -- but L4LAMP.cpp:252
commands flashFast + state1Dim + state2Bright, a dim->bright pulse that rendered
as a hard bright->off blink.  Three copies existed (l4vb16.h, L4GLASSWIN,
L4PADPANEL), all three wrong; the two locals now forward to the one fixed inline.

THE COCKPIT SCALES.  The fixed canvas was stretched into whatever the client
area was, so a window dragged to a different shape squashed the instruments (the
projection was aspect-corrected in task #20; the panels never were).  Now one
uniform scale, centred, leftover black.  D3D9 applies it as a Present
destination rect, which DISCARD forbids -- so the WINDOWED swap effect becomes
COPY when the surround is up and multisampling is off.  The click mapping had to
follow (mapping against the full client drifts the hit test off every button by
the bar width), as did the world aspect (under a uniform scale it is the view
rect's own).  -fit / -windowed-fullscreen: borderless over the monitor.

 - ordering trap: the first WM_SIZE beats the device, so a -fit boot logged
   aspect=3.14 and applied it on frame 1.  The letterbox INTENT is decided in
   btl4main; L4VIDEO only confirms or withdraws it.

PLAYER-TUNABLE DISPLAYS.  BT_MFD_SCALE (+ _UL/_UC/_UR/_LL/_LR), BT_RADAR_SCALE,
BT_RADAR_POS (CENTER/LEFT/RIGHT/MIDLEFT/MIDRIGHT).  The surround BANDS derive
from the resolved sizes -- that is why the sizes could not stay constants: the
band a display hangs in has to grow with it or the canvas clips it.  100%
reproduces the historical L276 R276 T223 B336 exactly.  A corner map goes flush
to the CANVAS edge and the lower MFD slides beside it (measuring off the view
edge overlapped them by 232px).

MAP LEGEND GRID -- measured, not inherited.  scratchpad/measurelegend.py over a
native capture: top 3, cell 102, pitch 107 of 640.  RP412's map is 13 + 6x102 @
105 -- same cell height, different top and pitch, so its numbers do NOT
transfer.  Our old even division had the pitch right by luck and sat 3px high of
the labels.

environ.ini.  It was read ~300 lines into WinMain, AFTER the platform-profile
block had run its getenv()s -- so every setting the profile reads was silently
ignored FROM THE FILE and only worked as a real env var.  It also putenv()'d
comments verbatim.  Now loaded immediately after the first-breath line, comments
skipped, the real environment WINS over the file, and a fully documented default
is written on first run (the bindings.txt convention: untracked, so
extract-over-top never clobbers a player's settings).

VERIFICATION HARNESS (new, reusable): BT_RIOBANK_LOG=1 dumps every bank;
checkbank.py proves no address is SHADOWED (an address whose rect is covered by
earlier buttons is dead however big it looks -- the overlapping under-glass banks
make that a live hazard); clickbank.py posts a real click at every button centre.

Verified: 72/72 placed, 0 shadowed, 72/72 dispatched in BOTH modes, after a
resize, at 150%/135%, and at 75%+BOTTOMRIGHT; wide/tall drags and -fit
undistorted on a 3440x1440; exploded/dock/pod/dev un-regressed.

arcattackandClaude Fable 5 1d31af61d7 Gitea #48: arm the artifact tripwires BY DEFAULT + surface detections through the matchlog
The user's ask: if the translation-table fix did not quite catch it, will the
next playtest LOG the artifact?  Before this commit, no -- BT_PLANE_AUDIT was
opt-in via env var, and playtest machines set none.

Changes (all engine L4VB16):
  * BT_PLANE_AUDIT is now DEFAULT-ON, =0 opts out.  Armed cost is a couple of
    integer compares per DRAW CALL (not per pixel); confirmed zero log noise
    on a clean default-env run post-fix.
  * A SECOND trap class: out-of-bounds draw STARTS, checked always-on in
    buildDestPointer (the funnel every primitive builds its pointer through).
    Release builds compile Verify() to nothing, so a wild start previously
    computed a silent rogue pointer into (or past) the shared buffer.  Now
    logged ([plane] OOB) and CLAMPED in-bounds.
  * First detection of each class writes a GLITCH matchlog record
    (kind=plane / kind=oob with position+color+mask), so the evidence arrives
    with the round logs the operator already collects -- unattended.
  * Both existing plane-leak trap levels (display primitives + the port-level
    pixmap table scan) flipped to the same default-on gate.

Honest coverage note (in gauges-hud.md): an in-buffer EXTENT overrun from a
valid start (a blit walking past the right/bottom edge into later rows of the
SAME plane) is not trapped -- per-pixel walk checks are too hot.  The plane
trap still catches any such overrun whose color leaks planes, which is the
class the night-3 artifacts belonged to.

Verified: full clean rebuild -- 40 pre-existing LNK2019 only (the
engine->game BTMatchLog linkage resolved, /FORCE-trap checked); default-env
probe run: 0 [plane] lines, game unaffected.

arcattackandClaude Fable 5 6bb03aed0b Gitea #48 ROOT-CAUSED + FIXED: MFD "stray blocks / misplaced lamps" = uninitialized translation-table entries leaking pixels into other displays' bit-planes
The conviction was empirical, not theoretical: a new write-site trap
(BT_PLANE_AUDIT) in the seven L4VB16 drawing primitives logs any draw whose
color carries bits outside its port's plane mask -- the exact cross-display
corruption condition (Replace ORs an unmasked color; Or/Xor ignore the mask
entirely; And clears foreign planes).  A quiet solo session produced 15-30
leaks per minute:

    [plane] PORT 'sec' pixmap draw at(0,0) idx 217 entry=0xffffff00 mask=0x3f
    [plane] LEAK DrawPixelMap8[table] at(639,0) color=0xffffff00 mask=0x3f leak=0xff00

THE DEFECT: L4GraphicsPort::translationTable[256] is never initialized in the
ctor, and BuildSecondaryTranslation fills only the entries its BitWrangler
reaches -- 2^numberOfBits: 64 for the sec plane (mask 0x3F), 4 for the overlay
(0xC0).  Entries above that stay heap garbage.  Every draw resolves color
through this table, and the PIXMAP path indexes it with raw pixel values
0..255: the 480x640 radar background carries pixel index 217, whose garbage
entry's high bits (0xFF00 = ALL EIGHT MFD planes) were stamped into the shared
640x480 buffer -- invisible on the culprit page (the in-plane bits happened
dark) and visible as bright fragments at the same coordinates on every OTHER
display.  That is the operator's screenshot exactly: the same-position blips
on Mfd1+Mfd2 and the Heat-display block.

FIX (engine, both layers):
  * zero translationTable in the L4GraphicsPort ctor (plane-neutral default);
  * BuildSecondaryTranslation now cycles the in-plane pattern across entries
    [2^bits..255] -- high-index art degrades to its (index mod 2^bits) colour
    IN-PLANE and can never leak.  The 1995 binary ships the SAME 64-entry fill
    and survived on 6-bit art discipline; garbage is not a preservable
    behaviour, so the cycle-fill is a guarded PORT deviation (documented).

A/B PROOF: same probe, 60s -- 0 leaks after the fix (15-30/min before).
sim3 3-pod regression: zero crashes.

SECOND real defect found + fixed en route: sessions configure the CAMERA seat
first ("cameraInit" -- which includes the MISSION-REVIEW context:
configure(0, sec, 0, 0x00FF, native, rgb, mrpal.pcc), a DirectColor context
whose translation tables legitimately hold full RGB565 values spanning all 16
plane bits), and the viewpoint swap to the mech re-configured WITHOUT tearing
that tree down (btl4app's s_gaugeTreeBuilt latch treats the mech build as the
first).  The orphaned review gauges kept executing through stale DirectColor
ports.  BTL4GaugeRenderer::ConfigureForModel now overrides (ConfigureForModel
made virtual in L4GREND.h) and tears the prior entity-bound tree down before
every rebuild -- safe on first build, and the review screen rebuilds the same
way when the seat returns to the camera.

Also logged (open-questions): the review-screen PlayerStatus panels read the
compiled player at RAW BINARY OFFSETS (+0x1FC vehicle / +0x1C8 score /
+0x1C4 alive-dead box) -- the databinding trap, dormant until the review
screen runs; bridge before enabling the review.

Ruled out along the way (with evidence): the pilot-list label/erase geometry
(erase box 128x32 covers the 64x16 name rasters), the radar name labels
(view-level ClipImage clips them), PlayerStatus in-game execution ([ps] probe:
never runs in-game), and the PNAME bitmap dimensions (egg generator emits
64x16 exactly).

Why it "started with the comms feature" (#43): that wave registered the new
gauge classes with the config interpreter, letting more of the authored page
furniture parse and draw than before -- the leaking high-index pixmaps rode in
with it.  [T3 correlation detail; the leak + fix are T2 live-verified.]

Diagnostics kept (env-gated): BT_PLANE_AUDIT (the leak trap, now a permanent
regression tripwire), BT_PS_LOG, the port-level pixmap identity trap.

KB: gauges-hud.md (#48 section), decomp-reference.md (BT_PLANE_AUDIT),
open-questions.md (PlayerStatus databinding entry).  checkctx CLEAN.

arcattackandClaude Opus 4.8 7052d9e5bb Cockpit: pull the MFD red lamps fully outside the screens; drop the flight blocks clear
Playtest feedback: the red MFD lamp buttons were obstructed (only a thin sliver
showed under the surface, crammed against the DISPLAY/PROGRAM legends), and the blue
THROTTLE/JOYSTICK flight blocks overlapped the bottom MFDs.

- Red lamps now sit FULLY OUTSIDE the MFD (kCkRedGap=3 off the edge, kCkRedH=24 tall)
  instead of reaching kCkRedCell into the display -- nothing occludes them and they
  read as real buttons, clear of the DISPLAY/PROGRAM legends. topBand grows to 223.
- Flight blocks drop below the MFD's bottom red lamps (belowLamp) -- no overlap.

arcattackandClaude Opus 4.8 129b27499d Cockpit surround: composite the gauges around the 3D view (default desktop layout)
Under BT_DEV_GAUGES the DEFAULT is now the pod-faithful cockpit surround: the 3D
world CENTERED with the six gauge surfaces composited AROUND it in the single main
window at 1/2 native scale, plus clickable RIO button lamps. Iterated as a visual
reference with the user, then landed in the engine.

- L4VB16.cpp/.h: BTCockpitLayout + BTCockpitComputeLayout (layout single source of
  truth, computed from the backbuffer canvas); BTDrawCockpitPanels (band fill ->
  button lamp quads -> 9-entry surface loop, phosphor-green mono / amber palette
  sec, Eng-sibling slot map -> GDI-atlas flight labels; D3DSBT_ALL state-block
  isolation = the floating-rocks trap); BTCockpitMouseDown/Up (client->bb hit-test
  + glass press/release/right-latch contract); BTApplyWorldViewport + DevGaugeDocked
  cockpit branches; shared BTLampBrightnessOf inline. Hooked at the top of
  BTDrawGaugeInset (before BT_SHOT, so shots include it).
- btl4main.cpp: glass preset (cockpit default, per-display panels opt-in); mode
  resolution -> gBTGaugeCockpit with work-area-clamped window sizing (-res = view
  size); WndProc WM_L/RBUTTON routing.
- L4VIDEO.cpp: BTWorldAspectOf cockpit branch (view rect on-screen aspect).
- L4VIDRND.cpp: CameraShipHUDRenderable::Render made viewport-relative.

Buttons = the L4GLASSWIN address banks x0.5 (Heat 0x2F, Mfd2 0x27, Comm 0x37, Mfd1
0x0F, Mfd3 0x07 red; radar rails 0x10-0x1B yellow; flight 0x38-0x47 blue, labeled).
Full rect is the hit target; the surface draws over it so only the lamp edge shows.
Precedence: BT_GLASS_PANELS=1 stands cockpit down > BT_COCKPIT=1 > _WINDOW/_DOCK
opt-out > cockpit default; BT_COCKPIT=0 = dock-bottom. Green tunable via
BT_COCKPIT_TINT. Renders in ALL builds; only the PadRIO click/lamp seam is
BT_GLASS-gated.

Verified (awaiting playtest): both build/ + build-glass/ compile (0 error C);
glass BT_SHOT matches the mockup; 500-click storm during a live mission survived
(Gitea #18 Receiver-gap fix holds); BT_COCKPIT=0 dock-bottom unregressed;
BT_GLASS_PANELS=1 stands cockpit down; pod build renders the panels.

CydandClaude Opus 4.8 f338595685 Glass cockpit: per-display windows (BT_GLASS_PANELS)
Break the desktop glass cockpit's secondary displays out of the single
combined pad panel + D3D gauge strip into ONE window per pod display, each
carrying that display's surface with its RIO button bank, arranged
pod-faithfully around the main view.  New TU engine/MUNGA_L4/L4GLASSWIN.*
(BT_GLASS-only), selected by the -platform glass preset via the new runtime
gate BT_GLASS_PANELS (=0 falls back to the legacy single panel + dock).

- Surfaces are CPU-expanded from the shared gauge buffer
  (SVGA16::ExpandPlaneToBGRA, no D3D) and StretchDIBits'd in -- the D3D
  dev-composite path (dock / window / overlay) stands down while active.
- Buttons sit UNDER the imagery: big hidden click targets that reach into
  the display, with only a small protruding edge showing as a lamp light.
  Red MFD banks tile the top/bottom; radar rails run the sides + a bottom
  row; a Flight Controls window hosts the no-display banks.
- Windows: Heat / Engineering / Comm / Left Weapons / Right Weapons / radar
  + Flight Controls; edge-to-edge (no in-client margin/title; OS caption
  labels each).
- Fix blank surfaces: application/ghWnd are duplicate-defined and bind
  non-deterministically under /FORCE, so the fresh L4GLASSWIN TU read NULL.
  Reach the renderer/window via BTResolveGaugeRenderer/BTResolveMainWindow
  defined in btl4main.cpp off the real btl4App/hWnd pointers.  New gotcha:
  reconstruction-gotchas.md S6 duplicate-GLOBAL corollary.

arcattackandClaude Fable 5 6783619069 Gitea #9: the upper-MFD PRESET pages (3 MFDs x 5) live -- SetPresetMode
table re-decoded to the ModeMFD bits + desktop J/K/L page cycle

The preset system was unwired by ONE defect in the message layer: the
SetPresetMode @004d1b24 table @0051dbf0 had been transcribed from the
section dump as BIG-endian dwords ({0x1e,0x01000000} instead of
{0x1e,0x01}), so a preset press set a garbage high bit -- and for group 1
items 3-4 / group 2 items 0-2 stomped the LIVE NonMapping / Intercom /
ModeSecondary* bits -- while the real page bits never moved.  Ground
truth (section_dump.txt:72901-72908, little-endian + BTL4MODE.HPP [T0]):
set = ModeMFD{1,2,3}{Quad,Eng1-4} = 1<<(group*5+item), bits 0-14, fully
disjoint from the #6 secondary trio (bits 18-20); group 2 is MFD3, NOT a
duplicate of the secondary views.

What the 15 presets show (l4gauge.cfg): group = the MFD (Mfd1 lower left
/ Mfd2 upper center / Mfd3 lower right), item 0 = the btquad.pcx Quad
overview (up to 4 vehicleSubSystems cluster panels), items 1-4 = the
full-screen engineering-detail pages (bteng.pcx + prepEngr screens
group*4+1..4 + the cluster eng children: GENERATOR SELECT A-D, POWER
graph, COOLING loop, DAMAGE, ammo).  Empty screens are authored per mech
(Blackhawk: 3/11/12 empty).

Authentic dispatch (streamed "L4" .CTL EventMappings, BT_CTRLMAP_LOG
dump): each MFD owns the 8-button RIO bank around it, MODE-MASK-gated --
Mfd1 = 0x08-0x0F, Mfd2 = 0x20-0x27, Mfd3 = 0x00-0x07.  Quad page ->
direct-select buttons for the POPULATED eng pages (mapper msgs
Aux1Eng1-4 0x4-0x7 / Aux2* 0x9-0xC / Aux3* 0xE-0x11); eng page -> one
back-to-Quad button (0x3/0x8/0xD) + per-subsystem controls.  These
records already install and fire on desktop (btinput passes the live
manager mask), so the NUMPAD profile's 0x20-0x27 keys page MFD2
authentically.

Port wiring (the #6 pattern): keys J/K/L -> actions Mfd1/2/3Cycle ->
gBTPresetCycle -> L4MechControlsMapper::CyclePresetModeNow(group) -- a
documented desktop shim (24 mode-dependent pod buttons don't fit a
keyboard) that cycles Quad -> populated Eng pages -> Quad, visiting
exactly the pod-reachable set; the body is the authentic SetPresetMode.

Dev-composite: BTDrawGaugeSurfaces now draws the Eng1-3 planes at their
sibling cells and skips any mono plane whose channel is BlankColor,
honoring the mode-driven reconfigure (RemapGraphicsPort) -- each dev
cell shows the ACTIVE page like the pod monitor.  This supersedes and
removes the 2026-07-12 GAUGREND "frozen-dial" scaffold (forced all 15
page bits active under BT_DEV_GAUGES; it pinned the shared Eng plane on
the highest screen and ate the page flips).

Pixel-verified (BT_PRESET_TEST + BT_DEV_GAUGES_DOCK + BT_SHOT,
Blackhawk): all three MFDs page Quad -> SYSTEM NN eng details -> back to
Quad in lockstep with the [mode] preset mask log; group 0 skips the
authored-empty screen 3, group 2 skips 11/12.  Un-regressed: N display
cycle (0x450421->0x490421->0x510421, page bits intact), M control mode,
CONTROLS.MAP 52 bindings parse clean.

Diags: BT_MODE_LOG ([mode] preset), BT_PRESET_TEST=<frame>.

arcattackandClaude Fable 5 48c9c8444f Fire VISUALS wave: the authored firesmoke sheet, vertex-alpha effect cards, the case-4 wreck dressing
The "fireballs like the demo vids" arc, decomp/content-grounded end to end,
plus the live-play UX batch verified over the same sessions:

FIRESMOKE SHEET (the PFX fireball fix): every firesmokeN_scr_tex in BTFX.VMF
maps the SAME 64x64 tileable noise image bintA (variants differ only in SCROLL
rate) and firesmoke1_mtl colours it through the "fiery" ramp (0.3,0.1,0.1)->
(0.9,0.7,0.3).  The particle layer now bakes ramp(lum(bintA)) as its sprite
colour (noise detail in alpha) and SCROLLS it at firesmoke1's authored rate
via a texture-transform; the port's radial soft-edge mask moved to a second
CLAMPed stage so the WRAPPED scroll rolls flame through the sprite without
scrolling the edge away.  Old grit x radial bake kept as the no-BINTA fallback.
Impact hits, damage-band smoke and death booms all ride this layer.

AUTHORED TEXTURE SCROLL in the model path: the BMF TEXTURE records carry
SPECIAL " SCROLL u0 v0 du dv" (tag 0x2037); the draw path always supported
per-op scrolling (SetTextureScrolling) but the BGF loader never parsed it, so
every scrolling material rendered frozen.  Wired TexRef -> MatInfo -> batch ->
L4TEXOP.doScroll: the flame cards (flamebig/fire5) now roll fire noise.

VERTEX-ALPHA EFFECT CARDS (the "twisted drill bit of fire" fix): FLAMEBIG's
verts carry authored float RGBA -- white-hot base (1.0,0.99,0.97) -> dark-red
tip fading to alpha -0.2 (the DPL clamp convention).  The loader kept a flat
batch colour and drew it OPAQUE = a solid orange spike.  Corpus sweep: exactly
14 shipped BGFs carry vertex alpha, ALL effect cards (flames, MUZFLASH,
EXDISK_A/B/C, TMST_A/B/C, beam models, DECLOUDS).  Such batches now keep the
authored per-vertex gradient and route to the alpha-blend pass, unlit,
colour = texture x gradient, alpha = the vertex fade; sky objects excluded
(drawAsSky + alphaTest passes NEITHER pass filter -- DECLOUDS stays in the
sky pass).  MUZFLASH/EXDISK render correctly for free when the muzzle-model
work lands.

WRECK DRESSING (the 1996 ExplosionScripts case-4 transcription): pieces spawn
HIDDEN and reveal 0.25s after the boom (the InstanceSwitch delay, behind the
dnboom flash); flamebig hangs over the pile, Y-BILLBOARDED at the camera
(SetOffsetYaw + a camera-pos getter -- the dpl_SetDCSReorientAxes analog);
the MakeDCSFall settle arms at the reveal with the two authored rates (hulk/
debris -0.025 t^2, fires -0.01 t^2 -- the flames ride above the sinking pile
and die with it at burial).  EMPTY-PLACEHOLDER hulk guard: THRDBR.BGF is a
153-byte zero-geometry stub that "loads fine" -- vertex-count check now routes
it to the gendbr fallback (a Thor wreck was invisible).  Hulk content census
recorded: AVADBR==MADDBR==VULDBR geometry (palette-only prefix diffs),
RAPDBR==SNDDBR==STIDBR byte-identical -- wreck variety is materials + the
dressing, not unique piles.

LIVE-PLAY BATCH: muzzle resolve uses the named segmentIndex (raw +0xdc read
was layout garbage); forward launch frame (authored MuzzleVelocity +Z vs the
mech's -Z facing); dock-bottom single window (gauge strip appended below the
world viewport, 1100x600 default, BT_DEV_GAUGES_WINDOW=1 restores the separate
window); portrait sec surface unrotated CW; ammo counters live via typed
bridges (BTAmmoBinCountPtr/BTAmmoBinFeeding/BTWeaponAmmoBin -- raw bin+0x180
and a hand-rolled link walk were garbage); fourth fire key ('4' = Pinky);
panel/arc probes de-aliased (%61 prime).

KB: rendering.md (vertex-alpha card family + scroll), combat-damage.md (hulk
census + THRDBR stub), gauges-hud.md (ammo bridges).

arcattackandClaude Fable 5 bb795e2805 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).

arcattackandClaude Fable 5 dd27238ceb Gauges: the CLOSEOUT wave -- radar pips, Myomers dedup, attribute parity, ledger sweep (tasks #14-#17)
TASK #17 -- AUTHENTIC RADAR SYMBOLOGY (the cross-blip stand-in retired).
The recon proved the 'missing pip raster set' never existed as BT game code:
pips are the ENGINE's L4GaugeImage vector-stroke system (T0 source in tree,
L4GAUIMA.cpp == FUN_0046f0c0 line-for-line), the 'pip table' is L4Warehouse::
gaugeImageBin keyed by Entity::resourceID, and BTL4.RES ships 110 type-0x12
shapes (every mech/vehicle/building/tree).  The six btl4rdr stubs are wired
to the real facilities: contacts draw their authentic model silhouettes with
LOD selection, the target gets the binary's 4px-inflated box highlight, and
player-name labels resolve via Mission::GetSmallNameBitmap (the prebuilt
64x16 egg rasters keyed by the player's bitmapindex).  DECODED: the invented
'VideoObject' was Entity::owningPlayer all along (+0x190; nameID =
playerBitmapIndex@0x1E0, target = BTPlayer::objectiveMech@0x284 -- new
bridge BTPlayerObjectiveMechOf); the 'LabelledEntity' class is Landmark
(cultural.h; label path dormant -- no landmark content ships, no runtime
landmarkID writer).  The L4GREND BT_DEV_GAUGES warehouse guard is removed
(its AV had a different culprit, below); resource type 18 corrected to
GaugeImageStream in decomp-reference (was mislabeled 'ModelList').

TASK #14 -- the Myomers ODR duplicate ELIMINATED: the powersub.cpp/hpp
'Myomers' (classID 0xBC3 -- actually Sensor) is retired whole; it duplicated
?DefaultData@Myomers@@ against the real class (dumpbin-verified) and /FORCE
picked the winner by link order.  The real Myomers (0xBC6) now chains
PoweredSubsystem's handler set (ids 4-8) and publishes its SEVEN binary
attributes (@00511588: SpeedEffect/Current/Recommended/Min/MaxSeekVoltage-
Index/SeekVoltage/OutputVoltage) -- the old empty unchained index starved
the Myomer engineering panel of every resolve.

TASK #16 -- attribute parity: MechWeapon publishes the FULL binary table
@0x511890 (11 entries; ids renumbered to binary truth -- the port aliases
had squatted the binary's DistanceToTarget/TargetWithinRange ids; the
streamed TriggerState 0x13 binding unchanged).  Binary names resolved two
TODO members: pipState -> estimatedReadyTime (attr 0x1A), and the EXT-model
flag is the binary's RearFiring (0x1B).  ThermalSight LightState published.
HUD (offset conflicts) + missile-side tables (id encoding suspect)
documented for a re-dump instead of publishing blind.
  THE CRASH THIS EXPOSED [T2, cdb-verified]: gotcha #11's dense-table gap
is a LATENT AV, not a guaranteed one -- the old table's 0x0D..0x12 gap
(task #5) survived on heap luck; the renumber reshuffled allocations and
Find() AV'd on a garbage entryName in WeaponCluster's PercentDone resolve.
Fixed with five named PAD entries (the mech.cpp attrPad idiom) + a
static_assert locking the pad base to PoweredSubsystem::NextAttributeID.
Gotcha #11 amended with the proof.

TASK #15 -- stale-ledger sweep: GAUGE_COMPOSITE ('composite not yet built',
Reservoir shadow, PlayerStatus/vehicleSubSystems 'remaining', valve-dormant-
until-0xBD3, sensor guard, the superseded 'Heat MFD near-static' reframe --
all banner-corrected), gauges-hud frontmatter, L4VB16 + powersub comments.

Verified live: 50/50 config attribute bindings resolve, 0 NULLs, 0 parse
skips, mech spawns and simulates 31/31 subsystems, no cross-blip fallbacks,
the pip cache fills through entity registration without the old guard.

arcattackandClaude Opus 4.8 b526e92cad gauges: all 6 cockpit MFD surfaces in a SEPARATE dev window (Milestone C)
Generalizes the single-'sec'-inset (Milestone B) into a full 6-surface
compositor presented in its own top-level window -- the default under
BT_DEV_GAUGES (BT_DEV_GAUGES_DOCK=1 docks it into the main window instead).
A 960x384 window tiles all six pod instrument screens: Heat (COOLANT/BALANCE/
RES + condenser gauges), Comm (KILLS/DEATHS/SELECT TARGET), Mfd1/2/3 (DISPLAY/
PROGRAM/NEAREST frames), and the color radar (SCALE grid + dials + ARMOR
DAMAGE). Main 800x600 3D view is un-occluded; default DEV un-regressed
(TARGET DESTROYED after 8 hits, 0 crashes).

Design (mapped by the mfd-multisurface-map workflow):
- All 6 surfaces are bit-plane MASKS over the ONE shared SVGA16/pixelBuffer
  (sec=palette low byte; Heat=0x4000 UL, Mfd2=0x0400 UC, Comm=0x8000 UR,
  Mfd1=0x0100 LL, Mfd3=0x1000 LR), so the compositor reaches the SVGA16 once
  and extracts each by mask. No port-name reconcile needed on the dev path --
  fetch the BT names directly; the RP aux* names only matter to the pod's own
  SVGA16::Update demux (a deferred pod-only fallback).
- SVGA16::DrawDevSurface: two kernels -- palette-LUT (sec) + mono bit-plane->
  tint ((word&mask)?tint:0). BTDrawGaugeSurfaces iterates a 6-entry table.
- Separate window = one CreateAdditionalSwapChain on the existing device (no
  2nd D3D device). BTGaugeWindowRenderAndPresent (after the main EndScene):
  SetRenderTarget -> SetDepthStencilSurface(NULL) -> Clear -> BeginScene ->
  6 tiles -> EndScene -> restore -> swap->Present.
- KEY BUG fixed: the main 800x600 depth surface stays bound when rendering to
  the 960x384 gauge backbuffer; a bound depth smaller than the RT is invalid
  -> all draws silently fail (clear color, no geometry). Unbind depth (Z is
  off), restore after.

Pod SVGA16::Update/BuildWindows path byte-unchanged; all gated BT_DEV_GAUGES.
Content is still the authored cockpit frames + base-table gauges -- the live
MFD widgets need the BTL4MethodDescription reconstruction (this window is now
the live viewer for that work). Details: docs/GAUGE_COMPOSITE.md.

arcattackandClaude Opus 4.8 a256813395 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).

arcattackandClaude Opus 4.8 c13e72d0ba platform profile + gauge dev-composite (Milestone A: gauge renderer woken)
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.

arcattackandClaude Opus 4.8 7b7d465e5e 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.
