User screenshot showed three artifacts, all one root cause: my dpl2d
executor drew OpenLines/CloseLines vertex runs as a connected LINESTRIP.
Every ctor use of OpenLines is SEGMENT PAIRS (4 crosshair arms, one pair
per ladder tick, the compass stem, the lock ring's 4 ticks, threat
marks) -- the strip joined ticks into zigzags ("squiggly lines" on both
ladders), hung diagonals off the crosshair arms, and drew chords across
the lock ring. Now D3DPT_LINELIST (one line per pair).
Also PIP_SPACING: _DAT_004cdce8 is a DOUBLE = 0.03 (read from the exe);
my 0.01 guess overlapped the 0.028-wide pips (user: "pips are
overlapping"). Reference-screenshot pairs sit side-by-side, matching.

A period pod screenshot from players who know the game flagged the
overlay. Stroke-by-stroke re-read of the ctor (@4546-4587) against it:
- The range caret triangle is GREEN width 1 (ctor @4550-4551 sets
SetLineWidth(1)+SetColor(0,0.75,0) AFTER the yellow bar's CallList) --
my transcription left it yellow/2. Same for the bottom bowtie carets
(@4569-4570). Both fixed; the caret polylines also get the binary's
explicit 4th closing point (@4558).
- The screenshot otherwise CONFIRMS our layout (yellow range bar, green
caret, colored pip dots, tick tape + green bowtie, rotating compass,
mid-ladder range with no lock = the world-pick terrain range).
- Its crosshair is ~2.5x taller with arrowhead arms -- NOT our binary's
+-0.04..0.16 program: a different pod revision. Ours stays [T1] to
BTL4OPT.EXE 4.10.

User report: after killing the enemy, wandering around, weapons won't
fire. Not a lock requirement -- the trigger pulse generator (the
1,0,1,0 edge feed for CheckFireEdge) sat inside `if (gEnemyMech != 0)`.
Once the wreck buried and gEnemyMech nulled, the channels froze at
their last value -> no rising edges -> no fire, even with a valid
terrain pick in the target slot. Latent since the world-pick model made
no-enemy firing meaningful (task #41); the weapon-group split kept the
pulses in the same wrong place.
The pulses now run unconditionally (before the enemy block); the
weapon's own HasActiveTarget gate remains the only fire arbiter --
terrain downrange fires at the scenery, a true sky shot (nothing within
1200) authentically refuses.
Verified: BT_AIM=0.5,0.3 (terrain-only picks, enemy never aimed at) ->
sustained fire, 123 laser + 82 PPC beam samples.

Interim pod-like grouping ahead of the authentic ConfigureMappables/
ChooseButton mapper channels (decomp-anchored in open-questions):
- Three fire channels like three pod buttons: gBTWeaponTrigger (lasers,
key 1 or SPACE), gBTPPCTrigger (PPCs, key 2), gBTMissileTrigger
(missiles, key 3 or CTRL). Keyboard only per user (mouse buttons
removed).
- EmitterSimulation picks its channel by classID (PPC 3028 vs Emitter
3016); BT_AUTOFIRE holds all three.
- The BT_BEAM_LOG sampler modulus 30 aliased to ONE weapon under the
new synchronized 5-beam volleys (5 | 30) -> 31 (coprime).
Verified: all 5 energy weapons fire (31 samples each), aimed hits land,
kill completes.

Answering "do lasers and PPCs fire together?": in the pod, grouping was
a PILOT CHOICE. MechWeapon message handlers id 9 'ConfigureMappables'
(FUN_004b9550) and id 10 'ChooseButton' (FUN_004b95b8), handler table
@0x511860 (names read from the exe): ConfigureMappables binds the
weapon's fireImpulse@0x31C to controls-mapper fire-channel #N (roster
slot 0; vtable +0x38 register / +0x3c unregister / +0x44 choose),
ChooseButton = the in-cockpit re-binding. Weapons sharing a button fire
together. The port's SPACE=energy / CTRL=missiles split is a stand-in
default; the authentic per-button channels are a tracked follow-up.

[hud] pip diagnostic logs each registered pip's classID/PipPosition/
WeaponRange/PipExtendedRange/PipColor. The live dump corrects the
"everything is 500m" assumption: BLH lasers red @500 (x3, ext=1),
missiles amber @800 (x2), PPCs blue @900 (x2) -- the pips sit at their
weapons' max-range marks on the range ladder (caret below a pip = that
weapon reaches), so 7 weapons read as 3 weapon-system groups. KB +
comments corrected.

User report: lock at spawn range (~120) but no damage until closing in.
The bring-up damage gate used kWeaponRange=100 -- a placeholder from
before the weapon reconstruction -- while the authored BLH weapon range
is 500 m. The binary's rule (FireWeapon @004bace8:7758 [T1]): damage
applies when dist <= the weapon's EFFECTIVE range = (1 - host-zone
damage) x authored WeaponRange -- the per-weapon targetWithinRange flag
UpdateTargeting computes each frame. The gate (and the [target] log's
IN WEAPON RANGE annotation) now reads that flag across the weapon
roster; kWeaponRange removed.
Verified: stationary at spawn range 120 -> IN WEAPON RANGE + 34 aimed
zone hits (was 0 until closing under 100).

The right-ladder caret reads range-to-pick, and with the world-pick
model the pick is usually the ground downrange -- so walking (cockpit
bob + turning sweeping the boresight across near/far terrain) made the
caret teleport frame to frame ("going all over the place", user
report). The binary rate-limits the DISPLAYED range: shown +=
clamp(true - shown, +-dt*500) -- a 500 m/s slide, applied in
HudSimulation, including toward the no-target 1200 default
(_DAT_004b7ed0 confirmed 0 = the abs() idiom). Implemented in mech4's
HUD feed where dt is in scope.

User report: enemy takes hits, starts smoking, then beams pass through
-- no more damage, no death. Root cause: the death-effects dispatch
(blhdead explosion chain + wreck swap + KILL score) lived in the
SHOOTER's laser fire block kill check. A missile killing blow lands
frames later in BTUpdateProjectiles -- outside that block -- and after
task #41 the boresight pick skips a dead mech, so the fire block never
ran against it again: the death chain was silently skipped, leaving an
internally-dead, smoking, standing, invulnerable mech.
Fix: the dispatch moved to the VICTIM's own once-per-death transition
(UpdateDeathState's movementMode->9 moment) -- fires exactly once for
ANY kill source (laser, missile, collision). Killer id for the
Explosion message = lastInflictingID (the task-#31 bookkeeping). The
BT_ENABLE_TEARDOWN cdb harness was removed with the old block (findings
preserved in docs/HARD_PROBLEMS.md).
Verified headless (75s soak, missile-heavy kill): destroyed ->
'blhdead' id=22 -> wreck swap 'blhdbr.bgf' -> smoke re-arm -> sink ->
buried INERT; post-death picks fall through to terrain; 0 crashes.

User video evidence (lasers firing at nothing) + the colleague's
torso-locked report + the binary all reconcile into one model:
The boresight pick hits the WORLD, and the target slot mech+0x388 holds
whatever entity is downrange:
- enemy mech under the boresight -> aimed target (hull point -> STEP-6
zone under the boresight, hotbox + lock ring, damage);
- else the TERRAIN downrange (BTGroundRayHit to 1200) -> the beam and
missiles fire at the scenery ("firing at nothing", as in the pod
videos), range caret reads the ground distance (authentic :5639), no
damage;
- else (sky) -> no target, and the weapon's own double 0x388 gate
refuses the discharge.
Binary evidence for non-mech targets: HudSimulation :5620 explicitly
handles a target WITHOUT damage zones (target->0x120 == 0) -- dead code
if only mechs were ever targeted. The pick is automatic every frame
(0x388: 11 reads / 0 direct stores in CODE).
Implementation: gBTTerrainEntity captured in MakeEntityRenderables
(Terrain::GetClassDerivations); mech4 pick = enemy PickRayHit else
ground ray -> terrain entity + ground point; damage/hotbox/lock only
for the mech pick; the task-40 enemy auto-converge REMOVED (facing away
now fires at the scenery, not magically at the enemy -- the user's
complaint). Verified all three states headless (BT_AIM 0,0 / .6,.5 /
0,-.8): aimed zone hits / terrain beams + 0 damage / no discharge.
Fourth (and evidence-complete) targeting model iteration; KB updated.

Colleague: you fire without a lock, at "nothing." Double-checked the
binary:
- The weapon fire path is DOUBLY gated on mech+0x388 != 0:
EmitterSimulation (FUN_004baa88:7689) only calls FireWeapon with a
target, and FireWeapon (FUN_004bace8:7727) wraps its whole body --
including beamFlag(+0x46c)=1 -- in the same check. So no target => no
beam, literally (cannot fire into truly empty space). [T1]
- BUT a capstone scan of the entire CODE section finds 11 READS of
+0x388 and ZERO direct stores: the target is written INDIRECTLY (a
message/selector), i.e. AUTO-acquired -- there is no manual lock to
fire. The spinning-ring LOCK (HudSimulation 5619-5634) is a separate,
stricter state.
So the colleague is right that no lock is needed; my port was wrong to
gate firing on a pinpoint boresight-on-hull pick. Fix: mech+0x388 = the
enemy whenever it is ALIVE (auto-target); firing needs only that. A
pinpoint hull hit upgrades the shot to aimed-zone damage + the lock
ring; off-hull with the enemy present, the beam converges on centre
mass (body hits). Third correction from over-reading the RP-shared
Reticle struct (after sticky-lock and mouse-cursor).
Verified: BT_AIM="0.5 0.2" (off-hull) -> fires + lands damage (was 0
before); BT_AIM="0 0" (centred) -> HOT-aimed zone hits. KB swept;
checkctx CLEAN.

Colleague flagged that targeting is torso-locked with no fine cursor.
Correct: the pod stick's yaw drove the TORSO TWIST
(MechControlsMapper -> HUD::SetFreeAimSlew(stick_x) @cockpit+0x28C,
gated on torso-horizontal-enabled; hud.hpp:167) and reticlePosition
@HUD+0x1FC is COMPUTED by HudSimulation from the mech pose quaternion +
target geometry, zeroed to centre with no target (part_013.c:5680) --
never a free-floating cursor. The engine Reticle struct is general
(shared with Red Planet); BT drives it from the torso boresight.
Fix:
- Removed the mouse-cursor slew (a mis-sourced stand-in from the
RP-shared struct). The crosshair is now the torso boresight:
BTTwistToReticleX(torsoTwist) = tan(twist) projected through the live
per-axis projection. Dead-centre on the fixed-torso BLH
(TorsoHorizontalEnabled=0); you aim by steering the whole mech.
- BT_AIM="x y" retained as the headless test harness.
Verified: face-to-face spawn -> HOT lock + aimed zone hits (36);
BT_FORCE_TURN circling -> 31 no-target vs 1 HOT (steering off-target
drops the lock, as it must). KB swept (combat-damage / gauges-hud /
open-questions); checkctx CLEAN.

- LOCK rules transcribed from the exported HudSimulation
(part_013.c:5619-5634): lock requires a target AND your own HUD host
zone damage < 0.75 (_DAT_004b7ec4 -- a shot-up targeting computer
drops lock) AND the targeted zone damage < 1.0 (_DAT_004b7ec8;
whole-mech target checks zone 0 -- a wreck's dead zone can't
re-lock). Box and ring are now separate signals like the binary:
gBTHudLockState 1 = target held (hotbox draws), 2 = LOCKED (+ the
spinning ring).
- SIMPLE-X mode: the ctor's [0x99] minimal-reticle list transcribed
(@4689-4705: green +-0.02..0.08 cross on the aim translate); Draw
switches master <-> simple X on the PrimaryHudOn element bit (0x20),
completing the recovered Execute's state-list logic.
- Canopy diagnosis sharpened (open-questions): blx_cop is the torso
segment's inside-skeleton mesh enclosing the eye; the black box =
the skeleton render branch missing its texture + PUNCH cutout (the
canopy windows are punch texels). A rendering-branch task; stays
hidden by default.

The one un-exported gap in the reticle chain, read via capstone
(tools/disas2.py; the annotated disasm preserved at
reference/decomp/reticle_execute_004cdcf0.disasm.txt). Draw() is now a
transcription of the real per-frame logic, and the HUD attr-table names
(hud.hpp ids 4/5/6/8/A/B/C/D) are CONFIRMED by their Execute usage:
- Range ladder: BAR from ladder-top to the caret + caret translate.
- The bottom 21-tick tape is the TORSO-TWIST indicator (NOT heading):
deflection = -/+(span/2) x (RotationOfTorsoHorizontal / twist limit),
attrs 4/5/6. Fixed-torso BLH reads centred -- authentic static.
- The circle-with-stem is the COMPASS (attr 0xD, rad->deg rotation) at
(botX, botY - 3*tickMajor - 0.03), with the THREAT trail (attr 0xC)
in its rotated frame: 0.05-unit attack-direction marks, fresh < 2s
red, expiring at 6s. Port feed: player TakeDamage pushes the impact
direction (dormant vs the passive test dummy).
- Pips (composed into subB6): hidden when destroyed (attr 1 == 1), LIT
when the fire cycle is LOADED (attr 0x1c == 2; port source
rechargeLevel >= 1) else the dark charging ring; filtered by the
weapon-GROUP bits (weaponMode & elementMask&0xF). Range plays NO part
(the stored TargetWithinRange slots are never read by Execute).
- Lock ring: subB9 at frame centre SPINNING 4 deg/frame while locked
([0x9d] is the spin matrix, not a heading list).
- Target HOTBOX: a rectangle hugging the projected extents (x+-4 around
the top-centre hotbox point, +1/-11.5 vertical; baked K=2.8145 -- the
port projects through the live per-axis projection), switching to the
edge arrows past +-1.6 or behind (BTProjectHotBox, L4VIDEO).
- Reticle state Off/On + PrimaryHudOn full-HUD/simple-X switch, aim
translate on slew move, 3D marker + PNAME player-name mesh identified
(chain still deferred).

sideways lock offset)
The windowed present stretches the fixed 800x600 backbuffer into the
client area while the projection's aspect follows the CLIENT (resize
rebuild) -- so the dpl2d/reticle frame, the client frame and NDC only
coincide for a backbuffer-shaped window. The mouse mapping and the
square-frame ray shortcut (cx = rx*tanHalfFov) were exact at screen
centre and drifted outward with a side-flipped sign: aiming left of the
enemy locked as if right of it (user report).
- BTSetAimProjection now publishes BOTH proj scales (P11 carries the
aspect) + the backbuffer size (the dpl2d frame). NOTE: GetViewport at
the loop top holds the PREVIOUS frame's last pass viewport (gauge
passes shrink it) -> use the renderer's own GetWidth/GetHeight.
- BTGetAimRay / BTProjectToReticle convert reticle <-> NDC per axis
(ndc_x = rx * vh/vw; camera x = ndc_x/P11) -- exact for any window
shape and FOV.
- New BTClientToReticle undoes the present stretch for the mouse
(client px -> viewport px -> reticle coords); mech4 uses it instead
of the raw client-height mapping.
- 1Hz aim telemetry in the [target] log (hits/noRay/noPick): verified
100% pick hit rate once the projection is live (the pre-visibility
mission-load seconds report noRay -- that was the "flicker").

The sticky lock made aim irrelevant after the first acquisition (the
crosshair starts on the face-to-face enemy, so it locked at spawn and
never let go -- played as auto-targeting). The binary treats no-target
as a frequent live state (fire path re-checks 0x388!=0 at every step,
part_013.c:7689/7727; HUD range feed has a permanent no-target default,
:5636), so the target slots now mirror the reticle pick each frame:
locked while the crosshair is ON the mech, no lock otherwise. Keeping
the crosshair on the enemy is the gunnery.
Verified headless: BT_AIM="0 0" -> HOT + aimed zone hits; BT_AIM="0.6
0.4" -> no lock, zero damage.

The engine Reticle model (MUNGA/RETICLE.h [T0]) reconstructed end to end:
- Mech::targetReticle is a real Reticle member bound to the TargetReticle
attribute (0x1d), per the RP VTV analog (VTV.h targetReticle).
- Crosshair slew: mouse -> client rect -> reticle coords (the pod stick
free-aim channel's dev-box stand-in); BT_AIM="x y" pins it headless.
LMB fires lasers / RMB missiles (alongside SPACE/CTRL).
- Pick ray: the ACTIVE eye publishes pos + LookAtRH basis (BTSetAimCamera,
L4VIDRND view-write site) + the render loop publishes proj._22;
BTGetAimRay builds the world ray, Mech::PickRayHit slab-tests it against
the collision template's ExtentBox via the engine's BoundingBox::HitBy
(local frame; clips the Line at entry) -> world hull point.
- Designation: the mech under the crosshair designates (sticky; re-hover
refreshes; cleared when the target leaves the roster at burial); the
entity target slots 0x37c/0x388/0x38c feed the whole weapon path.
- Aimed fire: while HOT the impact point is the PICKED hull point -> the
STEP-6 cylinder lookup resolves the zone under the crosshair (verified:
center-aim -> head-band zone 13 dominant). Off-crosshair the sticky
designation converges on center mass.
- HUD: the aim group draws at the slewed position ([0x9a] translate,
contained by push/pop); the designator ring tracks the target's
projected point (subB9 hot / subB8 designated, BTProjectToReticle);
edge arrows when off-screen/behind.
- AUTHENTIC gating: no fire arc exists in the binary (FireWeapon fires
whenever HasActiveTarget, part_013.c:7758) -> BT_FIRE_ARC is now an
explicit OPT-IN presentation clamp; the hardwired gEnemyMech lock and
the projectile path's gEnemyMech fallback are removed.
- Fixed en route: every renderable rebuild stomped mCamera back to the
chase eye (start-inside silently lost the cockpit camera; the aim feed
exposed it). BTL4VideoRenderer::mViewInside persists the chosen view.
Verified headless: BT_AIM="0 0" -> HOT lock, pick hits the hull face at
exact range, aimed zones resolve; BT_AIM="0.8 0.3" -> no lock, zero
damage, zero missile launches; kill chain completes to wreck + smoke.

The engine Reticle struct (the mech's "TargetReticle" attribute) is the
acquisition chain: slewable screen-space crosshair -> pick-ray -> the
entity + damage zone under it become mech+0x388/0x38c, the intersection
point mech+0x37c. Convergence-on-lock is authentic (FireWeapon has no
aim test); targetWithinRange = dist < (1-damage) x weaponRange
(FUN_004b9bdc). Port acquisition is a bring-up stand-in (hardwired lock
+ BT_FIRE_ARC cone) -> tracked as the next combat-fidelity step.

- dpl2d API fully recovered from the binary recorders (@487f34-488630):
opcode model (points/lines/polyline/circle/color/width/matrix/push-pop),
CallList = INLINE include (state persists to caller), centered coordinate
frame (unit = half viewport height). game/reconstructed/dpl2d.cpp rework.
- BTReticleRenderable ctor @004cc40c transcribed with the authentic
calibration (originX .35, originY .25, scaleY .5, 0..1200m right range
ladder, bottom heading tape, FUN_004cd938 tick ladders, lock rings,
turn arrows); range caret slides from the live target range fed by the
mech4 targeting step (BTSetHudTargetRange).
- Weapon pips: the binary gate is IsDerivedFrom(0x511830 =
MechWeapon::ClassDerivations) [T1: part_014.c:5386 hard-aborts on missing
weapon attrs; part_012 counts + roster ORs capabilityFlags@+0x334] so ALL
7 BLH weapons register (3 lasers + 2 PPCs + 2 MissileLaunchers). Pip A
(lit, authored PipColor) on TargetWithinRange, else dark ring B.
- AddWeapon @004cdac0 store map corrected to the verified order
(part_014.c:4827-4837); both state attrs are literally named
"SimulationState" (strings @51d526/51d577) -> weapon simulationState.
- Mech roster this[0x1ef] renamed poweredSubsystems -> weaponRoster
(0x511830 is MechWeapon, not PoweredSubsystem=0x50f4bc); derivation-tag
table added to context/decomp-reference.md.
- Draw hook BTDrawReticle after the 3D scene, cockpit view only. Binary
Execute @004cdcf0 is an un-exported gap -> Draw dynamics [T3], tracked
in context/open-questions.md with the blx_cop canopy + PNAME pip meshes.

Every dpl2d_ recorder in the binary self-identifies via its debug-name string
(part_010.c 0x487f34..0x4888c0) -- the complete API + opcode map is recorded
in phases/phase-02-dpl2d-reticle.md: point sets (2/3), closed polylines (4/5),
open line strips (6/7), AddPoint (8), AddCircle (9), SetColor (0xF),
Set/ConcatMatrix (0x10/0x11, 2x3 affine), Push/PopState (0x12/0x13),
SetLineWidth (0x15), CallDisplayList (nested glyphs), FullScreenClipRegion.
dpl2d.cpp reworked to that model: command-stream recorder (open-primitive
vertex runs, state commands, nested list calls) + a recursive ExecuteList
rasteriser (XYZRHW points/strips/loops/circles, 2x3 transform + state stacks,
save/restore). CORRECTION: the old "PushMatrix/MoveTo/PopMatrix" trio was a
misreading of OpenPolypoint/AddPoint/ClosePolypoint ("draw a point") -- kept
as aliases mapping to the true semantics.
Reticle findings recorded: the ctor (@004cc40c) builds ~15 display lists (the
dotted-cross reticle, tick ladders via FUN_004cd938, side arrows, arcs) plus a
3D marker chain and the PNAME1-8.bgf pip meshes (all ship). Next: transcribe
ctor+Execute, wire the 1996 caller's AddWeapon arguments, hook the draw.

- V toggles the authentic cockpit eyepoint <-> the chase camera. Both eyes
coexist; DPLEyeRenderable::Execute now writes the VIEW only when it IS
mCamera (unconditional writes let the last-executed eye stomp the toggle).
- EyepointRotation is a real zeroed EulerAngles member on Mech (was bound to
the shared junk attrPad -- the eye composes this attribute into the view
EVERY frame, so the cockpit camera was rotated by garbage: the canted
horizon, then the black screen). The eye-slew systems write it later.
- The cockpit eye mounts at the eyepoint's REST position with a clean upright
forward basis on the tree root (the live joint chain fed it the site tilt +
torso pose; authentic pitch/yaw is the deferred gyro eye chain).
- The inside view swaps the player to the INSIDE skeleton mesh set
(SkeletonType_A): 19 body segments hide, exactly one mesh remains --
blx_cop.bgf, the authentic cockpit canopy shell around the eyepoint. It
currently renders as a black enclosure (the black-screen report), so it is
HIDDEN pending its interior/punch-material rendering (BT_INSIDE_COCKPIT=1
shows it for that work). Damage gstates respected in both directions;
RemakeEntity keys off the DISPLAYED skeleton.
- Dev: BT_START_INSIDE=1 starts in the cockpit view.

Answers "can I keep targeting the dead mech?": the lock isn't cleared by
anything we've found, but the binary REFUSES to sustain energy beams on a
destroyed mech: ServiceDischarge (@004ba8d0) and ContinueDischarge (@004baa20)
check the beam's target EVERY discharge frame -- IsDerivedFrom(Mech) then
Mech::IsDestroyed (FUN_0049fb54 = movementMode 2||9) -- and kill the beam the
moment it dies. EmitterSimulation (@004baa88) applies the same check to the
OWNER (a dead mech's own weapons drop everything).
Our recon had FUN_0049fb54 as a mislabeled "cockpit/HUD query" no-op stub
called with NULL, and never set the beam's target (0x474) at fire -- all three
authentic gates were dead. Now: FireWeapon stashes the owner's target entity;
both discharge paths + the owner gate run the real check (BTMechDestroyed).
Verified: 40 beam samples before the kill, 0 after -- lasers flash-fail on the
wreck instead of cutting it like butter (heat is still spent per the binary's
FireWeapon, which fires blind; only the DISCHARGE checks the corpse).

The "cartoonish" beams: the port drew the ermlaser tube INFLATED -- a 3.0x
glow + 0.9x core two-layer hack, 13x the authored radius. Parsed the beam
models: ERMLASER/MLASER 0.22u radius, SLASER 0.11, LLASER 0.32, PPC 0.62 --
thin pencil beams with an authored per-class size progression; the PPC bolt
is genuinely ~3x fatter with its own 62-vert shape.
Now: ONE draw per beam at natural model scale (width multiplier 1.0), using
the weapon's OWN tube model (ermlaser for lasers, ppc.bgf for PPCs; the
s/m/llaser tubes load for other mechs' loadouts). BTPushBeamKind carries the
model selector; BTPushBeam keeps its signature (kind 0). Tint = 40+215x the
authored PipColor; the thin natural tubes stay under additive saturation so
the scrolling grit reads without a hand-dimmed core layer.

The visible beams now come from each weapon's own live state instead of the
hardcoded single-look stagger: FireWeapon arms beamFlag + dischargeTimer (the
weapon's authored DischargeTime), ServiceDischarge ends the window, recharge
gates cadence -- so volley-vs-stagger patterns, cadence and colours all emerge
from each mech's real loadout (BLH: 3 lasers + 2 PPCs). Per weapon: live
muzzle (its own mount; gun-port ordinal fallback when the mount doesn't
resolve -- GetMuzzlePoint returns the feet otherwise), the fire's stored world
endpoint, and the authored PipColor (lasers red 1,0,0 / PPC blue 0,0,1
straight from the .SUB data). PPC draws as a thicker, brighter bolt.
Filter is by EXACT classID (Emitter 3016 / PPC 3028) -- the derivation check
matched shared recon-stub chains (a Sensor and the MissileLauncher passed and
drew garbage beams from misinterpreted offsets).
The target slot (MECH_TARGET_POS) now carries the TORSO aim point (all
consumers -- beam endpoints, missiles, reticle -- want center-mass, not the
ground between the feet); the projectile fallback lift moved to match.
Accessors: Emitter::BeamOn/BeamEndpoint, MechWeapon::MuzzlePoint/PipColor.
BT_BEAM_LOG=1 samples the live per-weapon beam state.
Verified: [beam] PPC mz=(...,4.49,...) end=(...,7,...) rgb=(0,0,1) -- gun-port
muzzles, torso endpoints, authored colours; kill chain intact (10 hits).

The dummy spawned 120u along the player's forward with the SAME orientation,
so both mechs faced the same way and the player stared at its back (also why
first shots read as rear hits). Flip the enemy's yaw 180 deg about Y (engine
convention: Z basis = (sin y, 0, cos y) -> yaw = atan2(z.x, z.z) + pi) so the
two spawn face to face.

BT_ROSTER dump (the shipped subsystem stream is the authority): the pod
Blackhawk mounts 5 Emitters (two laser types) + 2 MissileLaunchers each with
its own AmmoBin -- the periodic missile volleys are the real loadout firing
on its own recharge, NOT a placeholder weapon.
What WASN'T authentic: one key firing everything (the bring-up collapse of
the controls mapper). Interim split toward the real weapon groups:
SPACE = energy weapons (lasers)
CTRL = missile launchers (the projectile-weapon channel)
New gBTMissileTrigger pulse; projweap's fireImpulse moves onto it; the
BT_AUTOFIRE harness drives both channels. The full controls-mapper weapon
grouping stays the deferred authentic reconstruction.
Also: BT_ROSTER=1 one-shot loadout dump (class name + id per subsystem).

The mech-vs-mech gather (Mover::GetCurrentCollisions) tests
mover->collisionVolume DIRECTLY -- it never consults collisionVolumeCount --
so the previous inert fix left the stale box blocking at the wreck spot.
The count-zero now serves only to stop MoveCollisionVolume from re-placing
the box, and the box itself is parked 100km underground where it intersects
nothing. Verified: the autodrive harness, previously pinned at ~7m from the
enemy, drives straight through the spot after burial (341,155 -> 992,-971).

The "white lines toward the feet" report: the LAUNCHES are authentic (the
mech's real MissileLauncher/ProjectileWeapon roster subsystems firing on
their own recharge cadence -- that's the every-Nth-shot rhythm), but the
visual was the bring-up 3-segment beam tracer, and the aim point was the
victim's ORIGIN (ground level between the feet).
- Trail: per-frame puffs of the AUTHENTIC dsrm effect (psfx 0, "the lrm
smoke trail") along the flight path, frame-oriented so the smoke streams
behind the round (its .PFX velocities are +Z = backward); the round itself
is a short hot streak. New BTPfxTrailPuff spawns slot particles directly
at a moving point (no emitter instance).
- Aim: the resolved target point lifts to torso height (the beams already
converged there) -- impacts now cyl-resolve to body zones instead of
diving at the feet/legs.
Follow-up noted: the round MESHES (BULLET/LRMS.BGF ship) for a true
model-per-projectile look.

Answers "it's still there but invisible": not normal -- the real game removes
the dead entity (death row). Full entity teardown needs the mech render tree
unhooked from the renderer first (the remaining P5 follow-through), so until
then the burial transition makes the wreck behaviorally gone:
- collisionVolumeCount = 0 (the collision gather skips volume-less movers;
MoveCollisionVolume early-outs) -> no phantom blocking
- the player's target lock drops -> beams stop converging on / hitting the
empty spot, no phantom impact smoke
Verified: zero [damage] hits after burial; INERT fires one-shot at
"wreck buried".

Answers "does the wreck fade away?": YES, by sinking. FUN_00456410 (the 1996
sink renderable) computes offsetY = rate * t^2; the hulk's authored rate is
-0.025 -> the ~7-unit hulk is fully underground ~17s after the kill. The
script also pairs the standing hulk with the LDBR strewn-debris field (12x13u
flat scatter), parented together and sinking together.
Also verified from the mesh data: BLHDBR (1537 verts -- more than the intact
torso) IS the authored Blackhawk wreck: the classic standing-leg-in-rubble
sculpt. The "just a leg standing there" report is the authentic art.
(THRDBR -- the mesh the 1996 script hardcoded -- parses to ZERO vertices;
more evidence the hardcode was an unfinished dev shortcut.)
Implementation: SwapToWreck adds the ldbr piece; TickWreck applies the
quadratic sink per frame (driven from the dead mech's UpdateDeathState),
hides both pieces at burial and reports it so the wreck-smoke re-arm stops
with the wreck. DPLStaticChildRenderable::SetOffsetTranslation added
(Execute re-reads OrientationMatrix per frame -- same in-place idiom as
SetDrawObj).
Lifecycle verified live: kill -> 'blhdbr.bgf' + ldbr debris -> smoke re-arm
@10s -> wreck buried @~17s -> smoke stops.

The user was right: a dead mech turns into a pile of wreckage. The authentic
1995 chain, recovered end-to-end:
kill -> the victim's per-mech DEATH ModelList ('blhdead'/'lokdead'/'owndead'/
'thrdead', .RES ids 22-25) -> its authored effects: 104 (the WRECK script) +
1007 (dnboom big explosion) + 1001 (ddthsmk rubble smoke plume) + a damage-
smoke burst (3/4/5/15).
Effect 104 = ExplosionScripts case 4 (part_008.c:2663, LIVE in the 1996 binary;
the "disabled" warning is case 6): loads the destroyed hulk + flamesml/flamebig
flame meshes with sweep flicker. Every mech ships its hulk (BLHDBR/MADDBR/
LOKDBR/... + GENDBR generic); the 1996 script hardcoded thrdbr.bgf (dev
shortcut) -- we use the victim's own.
Reconstructed as BTL4VideoRenderer::SwapToWreck: hide every segment mesh, hang
"<prefix>dbr.bgf" on the tree root (pending-swap if death precedes tree build);
routed from the engine's ExplosionClassID dispatch (effect 104 ->
BTSwapMechToWreck(explosion->GetEntityHit())). The kill now fires the
authentic 'blhdead' resource (manual 7+1 pfx calls removed -- the list carries
1007/1001 itself). Verified live:
[death] firing authentic death list 'blhdead' id=22
** effect_number = 104
[BTrender] wreck swap: victim -> 'blhdbr.bgf'
Follow-ups noted: mesh flames + hulk settle (cosmetic), DeathSplash.

The one-burst emitter batching was wrong: in EVERY shipped .PFX,
maxIssue/rate == release_period (DAFC 25/100~=0.2, DNBOOM 35/150~=0.2, DDAM2
35/16~=2, DDTHSMK 30/3=10) -- release_period is the EMISSION WINDOW and rate
is particles/second emitted continuously across it. The death smoke plume is
authored as a 3/sec trickle for 10 seconds (+6s particle life), not one
same-frame puff. Emitters now integrate rate*dt until maximum_issue.
Wreck smoke (port addition, [T3]): a destroyed mech re-arms the death/rubble
smoke plume (psfx 1, DDTHSMK) every 10s -- its own authored window -- so the
dead hulk visibly keeps smoking instead of standing there looking alive (the
freeze-death is invisible on an already-stationary target). New member
Mech::wreckSmokeTimer; UpdateDeathState takes dt.

Task #32 (death collapse animation) resolved by decomp evidence -- BT 4.11 has
NO collapse animation; the movementMode 5-8 fall latch (clips 0x1c-0x1f) is an
engine-lineage vestige:
(1) the clip-table loader FUN_004a80d4 fills slots 0x00-0x1b + 0x20 (bmp
knockdown) and returns -- slots 0x1c-0x1f are never written;
(2) mech+0x63c..0x648 appear in NO exported function;
(3) no fall clip exists in the shipped 27-clip set;
(4) firing the latch would bind resource id 0 -- a StaticAudioStream -- as
keyframes.
Authentic death modes are the FREEZE modes (IsDestroyed == mode 2||9), so
UpdateDeathState now settles straight to 9 (was a [T3] mode-5 guess that would
trip the garbage latch in the binary). The death READ = freeze + dnboom +
ddthsmk smoke plume + destroyed skins + shutdown; the wreck stands.
Also: damage-band effects orient toward the ATTACKER (impact frame) via
lastInflictingID -- which was declared but never written (recon gap); now
maintained by Mech::TakeDamageMessageHandler, unblocking the DamageZone LOD
same-attacker redirect too.
KB corrected + proofs recorded (combat-damage "Death SEQUENCE", open-questions).

The 'can't kill the enemy / no visible damage' cluster, root-caused and fixed
faithfully:
- STEP-6 unaimed path was INERT: the cylinder table was 'cached' at Wword(0x111)
-- the recon ABSORBER bank (stores nothing, reads 0) -- so every unaimed hit
silently no-op'd. Promoted to the named member Mech::damageLookupTable
(binary this[0x111], was mislabeled ammoExpended). New gotcha class recorded
(reconstruction-gotchas §2) + sweep; 2 dead multiplayer branches logged.
- Fire path migrated off the stale vital-zone aim onto the completed STEP-6
unaimed dispatch (zone=-1 + beam entry point -> cylinder resolves the
exterior zone). No more invisible 1-shot kills; death via the authentic
cascade (~14 center-mass hits). Wreck stays TARGETED on kill (beams stop on
it); scoring latches off.
- SendSubsystemDamage AV fixed: unbound critical-subsystem plug guard (43
unbound plugs/mech logged as an open question -- the binding itself is a gap).
- RemakeEntity (render damage swap): the 1996 render state machine's missing
Remake state, reconstructed as an in-place SetDrawObj mesh swap keyed by each
segment's damage-zone graphic state (tree dtor doesn't cascade -> never
rebuild). Destroyed arms/guns visibly wreck (the only variants the RES
registers).
- BT .PFX particle layer (L4VIDEO.cpp): the 1995 explosion/damage effect layer,
unported since 2007 (DPLIndependantEffect/ReadPSFX/ExplosionScripts all
stubs). Parses the authentic VIDEO/*.PFX definitions via the [pfx_day]
psfxN mapping; premultiplied blending renders BOTH families from the same
data (additive-style fire + occluding smoke -- DDAM2 is 30% grey, DDTHSMK
ramps negative: impossible additively); depth-sorted billboards with a
radial-masked grit sprite; impact-frame orientation (.PFX offsets are
authored mech-local, -Z = out of the struck armor toward the shooter) for
weapon hits AND damage bands (via lastInflictingID, now maintained -- was
declared but never written). Both effect-number encodings route (raw dpl
<100 + WinTesla 1000+slot carried by the band resources). Death fires the
authentic dnboom (7) + ddthsmk smoke plume (1).
- Effects anchor at the impact point / damaged zone's segment, not the mech
origin (no more fire at the feet).
- Dev force-input gates BT_AUTOFIRE / BT_AUTODRIVE for headless fire-chain
verification; BT_PFX_ADD=1 flips the particle blend for A/B.

Fixes the "kills are invisible" report: a mech died only at the state level, with
no visible destruction on its body. Root cause: the per-zone damage-state
descriptor table (binary zone+0xd4) that drives destroyed-skins + explosions was
never built -- its loader (Mech__DamageZone::LoadCriticalSubsystems / FUN_0041e4a8)
was a no-op stub, and MechDeathHandler itself was a no-op stub. The surrounding
plumbing (the per-zone load loop over the type-0x1e resource, the death-handler
slot) was already correct. Whole pipeline is EXPORTED -- no stand-ins.
Reconstructed:
- Mech__DamageZone descriptor table (binary this+0xd4): un-stubbed
LoadCriticalSubsystems (FUN_0041e4a8/FUN_0042a748/FUN_0042a2c8) to parse the
real type-0x1e stream -- entry = [f32 DamageLevel][i32 EffectResource]
[i32 GraphicState][f32 TimeDelay], ascending by DamageLevel. Verified live:
6 entries/zone, first threshold 0.2, effect 26, across all 40 zones, no crash.
- The three lookups (FUN_0042a664 by-level / FUN_0042a5f4 crossing / FUN_0042a6c4
by-graphic-state) as Mech__DamageZone methods.
- The real MechDeathHandler (FUN_0042a984 ctor / FUN_0042aa2c Performance /
FUN_0042a9f4 dtor), replacing the stub: each tick it walks the zones and, as a
zone's damageLevel rises across a descriptor threshold, fires that entry's
explosion (binary +0xb8 & 4) and, on destruction, the Destroyed-graphic
descriptor's explosion (+0xb8 & 8), applying the descriptor's GraphicState (the
destroyed skin) to the zone. Runs for EVERY mech, so the enemy visibly falls
apart as it dies.
Integration: the binary ticks MechDeathHandler off the mech's Performance list
(mech+0xbc), which the bring-up drive override bypasses, so Mech::PerformAndWatch
drives Tick() directly (same approach as UpdateDeathState). Effect spawn uses the
established Explosion::Make port (BTSpawnDamageEffect) -- the authentic dispatch
(class-5 message -> the 0xBD3 SubsystemMessageManager effect manager) is unported.
Runtime: builds clean, boots clean, 42 descriptor tables load with sensible
byte-aligned data, no crash. Live effect firing is combat-triggered (verified by
the load + the wiring; the [deathfx] threshold-crossing log fires under BT_DEATH_LOG).

Reconstructs the mech DEATH state machine — the un-exported master-perf death
branch (region 0x4a9770-0x4ab188) — from its EXPORTED consumers + the RP
VTV::DeathShutdown analog, wired into the active path (the bring-up drive
override bypasses the authentic Simulate where this normally lives).
Mech::UpdateDeathState() + IsMechDestroyed() (mech4.cpp), called for every mech
early in PerformAndWatch: on a vital kill (graphicAlarm >= 9, raised by the
damage side) it
1. sets movementMode = 5 -> the collapse clip's one-shot latch in
AdvanceBodyAnimation (fall direction 5-8 is un-exported -> 5 [T3]);
2. loops the roster calling Subsystem::DeathShutdown(1) (RP VTV::DeathShutdown
analog; the base is a no-op virtual, overrides act -- a SHUTDOWN not a
teardown, so it frees nothing and never removes the entity: the wreck STAYS);
3. next frame settles to movementMode = 9 -> IsDisabled -> locomotion frozen.
The drive's lone `movementMode = 1` write (mech4.cpp ~1309) is guarded on
!IsMechDestroyed so the death state is not clobbered back to a live gait.
Runtime-verified (forced kill, BT_DEATH_LOG=1):
[death] mech destroyed -> collapse + subsystem shutdown (wreck stays)
[death] mech settled -> disabled (IsDisabled=1, frozen wreck)
mech frozen in place, subsystem tick + renderer keep running, no crash, wreck
stays.
Also records the full death-sequence decomp map in combat-damage.md (the
exported consumers: AdvanceLeg/BodyAnimation collapse latch, IsDestroyed, the
MechDeathHandler effect engine; and the un-exported orchestration gap).
Deferred (honest): the visible collapse ANIMATION latch through the active path
(gait SM shows state=0 post-death; spawned mechs don't advance body anim);
MechDeathHandler (FUN_0042a984/FUN_0042aa2c -- the exported per-subsystem
destroyed-skin + explosion engine, still a stub) for death explosions; the
whole-mech DeathSplash radius damage (un-exported).

The two deferred TakeDamage dispatches in Mech::ProcessCollision now fire,
unblocked by STEP 6 (the cylinder hit-location override that resolves zone==-1):
- Mover branch (:15324-15358): on a collision with another Mech, dispatch the
collision damage to it.
- CulturalIcon branch (:15369-15401): crunch dispatch to a building/tree/prop,
before the walk-through sentinel overwrites the amount.
Both go through a new file-scope helper BTDispatchCollisionDamage, which builds
an Entity::TakeDamageMessage{zone==-1} (the engine ctor -- same idiom as the
weapon-impact path) with the world centre of the overlap slice as the impact
point and this mech as the inflictor, then Dispatch()es it to the victim. The
receiver turns the world impact point into a damage zone: a Mech via its cylinder
table (STEP 6), an icon via its base handler (crushable props have no zones -> a
harmless no-op). Terrain (walls/hills) matches neither branch, so it still
BLOCKS without damage (faithful to the binary).
Faithful to the binary's raw DamageMessage dispatch (:15324-15401) but via the
engine's named TakeDamageMessage API (no databinding-trap field-by-field build);
the binary's inflictor global DAT_0050b9ac is a sentinel EntityID (only ever
read, never set -> a collision has no "shooter"), so this mech is the inflictor.
Verify: builds clean; reachability GUARANTEED (Mover::ProcessCollisionList calls
the VIRTUAL ProcessCollision -> Mech::ProcessCollision, on the active
AuthenticGroundAndCollide path); stable across runs; both mechs build their
cylinder tables. The live dispatch was not captured headlessly (the solo
auto-walker never rammed a tree/mech), but the path is proven reachable and
composed of runtime-verified pieces (the weapon TakeDamage path + STEP 6).
Also validated STEP 6's height ref: collisionTemplate->maxY ~= 7.1 (a real mech
height), confirming CylinderReferenceHeight reads a height (not the heat value
the mech+0x2ec dual-labeling hinted at).

The Mech per-impact hit-location resolver (the cylinder damage table) is now
functional, wired, and runtime-verified [T2]. Unaimed (zone==-1) hits — the
collision-damage path — now resolve an impact point to a damage zone via the
authentic height x angle grid + weighted dice roll, instead of dropping.
dmgtable.cpp/.hpp was a non-functional skeleton on no-op ReconTable/stream
shims; backed it with real std::vector storage and fixed 5 latent runtime bugs:
- ReadEntries now consumes the leading cell name-string ([i32 len][len+1])
- PieSlice ctor reads rotateWithTorso into the correct member
- SelectSlice direct-indexes (was int lookup on a float-keyed table)
- ResolveHit returns the zone (chains SelectSlice -> SelectZone)
- real MemoryStream::ReadBytes (was a variadic no-op)
mech.cpp ctor: replaced the empty-name StandingAnimation stub with the real
load — FindResourceDescription(dzRes->resourceName, type 0x1d) -> stream ->
new DamageLookupTable, cached at mech[0x111]; ~Mech deletes it.
Mech::TakeDamageMessageHandler override registered (MESSAGE_ENTRY overlays
Entity's by ID): on invalidDamageZone, resolve via the table then base-route;
aimed reticle hits pass through unchanged.
Three named accessors (no databinding-trap raw reads): WorldToLocal
(localToWorld.MultiplyByInverse), CylinderReferenceHeight (standingTemplateMaxY
== collisionTemplate->maxY == binary mech+0x2ec[+0xc]), TorsoHeading via a
BTGetTorsoTwist bridge in torso.cpp (Torso::CurrentTwist == torso+0x1d8;
torso.hpp cannot be included into mech.cpp — subsystem-stub collision).
Stream format + geometry + roll + handler were all byte-verified against the
shipped BTL4.RES type-29 resources (18 tables, exact consumption) and the
disassembly (FUN_0049eb54/e678/de14, glue 0x49ed0c, handler @0x4a037a).
Runtime: boots clean, "[cyl] table 'bhk1' layers=7" (exact byte-verified layer
count, found by name), mech spawns + walks, no asserts/AV/0xCDCDCDCD. Env gate
BT_CYL_LOG=1. Unblocks collision-damage application.

De-risk + format-reversal pass complete. The CylinderDamageZoneTable is a passive nested-list
height x angle grid: TABLE (FUN_0049ea48) -> ROWS-by-height (FUN_0049e740, cell key i*2pi/count,
_DAT_0049e810=6.2831855) -> CELLS-by-angle (FUN_0049deb0) -> zone. All 3 vtables minimal (dtor +
2 Node slots, NO lookup method) -> the lookup is entirely in the unexported
Mech::TakeDamageMessageHandler (handler-set entry, not virtual) = the disassembly target.

Per the 'correct errors' convention: the cited FUN_004a0230/FUN_0049ed0c don't exist. The real
CylinderDamageZoneTable = a list of 0x30-byte entries (FUN_0049e740) from resource 0x1d; the recon
builds the table (FUN_0049ea48, mislabeled StandingAnimation @Mech[0x111]) with an EMPTY name -> 0
entries -> no-op. The lookup + Mech::TakeDamageMessageHandler override are NOT in the exported decomp

The context system is a reconstruction; some claims are wrong. When the decomp/binary/engine
source contradicts a context/glossary/docs claim, FIX it + grep-sweep the same claim across the

Propagate the verified finding (0xBD3 = damage/explosion hub @0x434, NOT the valve/message
gate; the valve/Myomers gates read the owning BTPlayer @mech+0x190) into the topic files that
still carried the old claim: decomp-reference (ClassID row + both offset rows), gauges-hud,
subsystems, open-questions (Myomers coupling), + frontmatter. Graph validates clean.

The valve/Myomers 'gates' (FUN_004ac9c8 / FUN_004ad7d4) read the owning BTPlayer's
+0x274 / +0x260 (mech+0x190 = the player, bound by FUN_0049f624). So there's no new
subsystem to build -- the wiring is 2 gate accessors -> GetPlayerLink() named members.
Open: the true semantics of player+0x260/0x274 (scoring names showKills/roleClassIndex
may not match the gate use) + the FUN_004ad7d4 HeatModelActive-vs-OwnerAdvancedDamage
label conflict + these are likely MODE flags authentically-off in the basic mission.

Risk-4 investigation (before wiring WAVE 8) found my earlier 'keystone unblocks 4 things'
claim was wrong. Verified from the binary:
- 0xBD3 SubsystemMessageManager = a damage/explosion consolidation hub (ConsolidateAndSendDamage,
weaponExplosions), cached to Mech[0x10d]=0x434, mislabeled 'controlsMapper' in our recon (the
live drive squats there; the real mapper is roster slot 0 via SetMappingSubsystem).
- The valve MoveValve guard (FUN_004ac9c8 ->owner+0x190+0x274) AND the Myomers gate
(FUN_004ad7d4 ->owner+0x190+0x260) read a DIFFERENT object at mech+0x190 (!= 0x434). So 0xBD3
does NOT gate the valve/Myomers/MessageBoard; mech+0x190 (unidentified, no decompiled writer yet)
is the real keystone for those gauge-adjacent routes.
