The pre-launch host drop/rejoin re-stream re-creates every mech at mission
launch; the LOBBY-built gauge tree kept attribute pointers into the freed
first-stream mechs, every widget Execute AV'd, and the BT_DEV_GAUGES SEH
guard (Gauge::GuardedExecute, GAUGE.cpp:618) disabled each one PERMANENTLY
(rate=0, no rebind) -- the frozen dev-gauges window of incident #12. The
authentic engine flow only tears the tree down at mission transitions
(Application::Shutdown -> gaugeRenderer->Shutdown() -> ShutdownImplementation
-> Remove(0), APP.cpp:787 / GAUGREND.cpp:3264); the re-stream bypassed it.
Fix: BTL4GaugeRenderer::TearDownForViewpointRestream() performs the
ENTITY-BOUND half of that same ShutdownImplementation sequence, in order
(gaugeAlarmManager->RemoveAllAlarms() -> Remove(0) -> moving/static entity
grid Clear), keeping the mission-scoped state (warehouse, graphics ports,
interpreter, controls-owned L4Lamps -- RemoveAllLamps would delete them
behind the buttonGroup's &lamp->automaticValue registrations). Called from
BTL4Application::MakeViewpointEntity before ConfigureForModel("Init") on any
viewpoint RE-make -- that handler runs once per stream (the incident log's
[ctrlmap] installing x2) -- so the tree rebuilds bound to the NEW mech via
the renderer's existing lazy build. Sentinel: "[gauge] viewpoint re-stream:
tearing the gauge tree down for rebuild".
Verified with the 2-instance relay harness (port 15600, MP_RELAY.EGG,
the incident sequence): join A (dev gauges) + B, kill B by exact PID at
WAITING FOR OPERATOR LAUNCH, rejoin B, operator launch. Pod A re-streamed
(2x ctrlmap install, 4x zonebuild), logged the sentinel, and post-launch the
docked composite is fully live (mission clock/heading/radar advancing between
BT_SHOT frames) with ZERO [gauge-fault] DISABLED lines (the incident had 11).

- manifest410.py: monotone-DP TU labeling (data-cluster affinity + CLASSMAP
seeds + recon @addr soft votes) replaces naive fill; BT region = 917 fn /
~230 KB, extents match every independently-known TU boundary.
- source-completeness: ROUTE A CLOSED (Nick holds no further assets);
toolchain = BC++ 4.52 PROVEN by CW32.LIB byte-match, archived at
TeslaRel410/BORLAND; OPT.MAK = the shipped binary's exact recipe; extender
corrected to Borland PowerPack DPMI32 (was "Phar Lap TNT"); "all BT headers

engine gaps enumerated (vdata.hpp first, back-dated from BT412).
- phases/phase-03: rounds 1-3 of the source410 campaign - 6/10 surviving
originals compile clean under BC4.52; console wire IDs recovered from the
binary ctors (Killed=9 Damaged=10 ScoreUpdate=13 DWH=15 [T1], TeamScore

Brings Cyd's experience-level / simulation-mode research onto master (the
KB-decode portion of glass-cockpit 4e01e83; the bundled BT410 source
manifest is left for the full glass-cockpit merge).
- context/experience-levels.md (NEW): the egg per-pilot 'experience' field
(novice/standard/veteran/expert) is the pod's SIMULATION-FIDELITY tier,
decoded end-to-end. FUN_004c0bc8 reads btMission->experienceLevel(+0xe4)
and fans it into the +0x25c/+0x260/+0x26c/+0x270/+0x274 flag block:
+0x25c 'sim live' (novice lockout: jams/searchlight/powersub), +0x260 the
HEAT-MODEL master switch (veteran+expert; FUN_004ad7d4), +0x274 raw level
(FUN_004ac9c8 = ==0 novice predicate; the valve/advanced-cockpit lockout).
4.0->4.10 drift: the viewscreen hunting-aid gate is GONE in 4.10 (HUD reads
none of these flags), and movement heat is veteran+expert not expert-only.
- btplayer.cpp/.hpp: CORRECTED comments/labels -- the +0x25c..+0x274 block is
seeded from btMission experienceLevel/advancedDamageOn, NOT the scenario
role's returnFromDeath; the 'roleClassIndex/showKills' names are scoring-era
mislabels. Code logic UNCHANGED (comment-only): the ctor still reads
scenarioRole (STAND-IN, defaults 2 = veteran) pending the wiring task.
- Corrections swept into gauges-hud.md (ROOKIE->novice lockout),
open-questions.md (player+0x260/0x274 semantics now PINNED),
pod-hardware.md, subsystems.md, decomp-reference.md; CLAUDE.md router row.
No code-logic change -> no rebuild needed (comment + markdown only). The
runtime wiring (seed from BTMission::ExperienceLevel()) remains TODO.

The egg's per-pilot 'experience' (novice/standard/veteran/expert) is the
pod's simulation-fidelity tier -- stored at BTMission+0xe4 and seeded into
the BTPlayer ctor's flag block @4c0bc8 [T1]. The old 'per-role display
toggles / returnFromDeath' reading was WRONG: the source is
mission->experienceLevel, and the neighboring pair copies
mission->advancedDamageOn (the egg's technician splash/collision switch),
not role floats. Known consumers: 0x260 = the HEAT-MODEL master switch
(FUN_004ad7d4), 0x25c = the novice sim-lockout (jams/searchlight/powersub),
0x274 = the raw level (FUN_004ac9c8 ==0 novice predicate).
NEW established topic context/experience-levels.md (data path, binary flag
rows per level, manual cross-refs, corrections log) + router row; sweeps in
decomp-reference/gauges-hud/open-questions/pod-hardware/subsystems.
btplayer.cpp/.hpp re-annotated with the corrected semantics; the guarded
role-based seeding stays as a marked [T3] stand-in (slot drift vs the
binary switch documented inline) until the wiring task points it at
BTMission::ExperienceLevel().

The stubbed dpl-instance ranking display is reborn as screen-space
quads in CameraShipHUDRenderable::Render:
- followed-player callsign banner (bottom center; the old direct
index was correct -- Execute already converts to the 0-based
texture slot)
- the RANKING WINDOW: one row per scoring player, [ordinal][callsign]
in rank order right of center; visibility = the Director's
authentic flash logic (10s on / 15s off, solid final 30s); rows
follow LIVE playerRank pointers so they re-sort as scores change
- discovery: each 128x32 ordinal bitmap packs TWO ordinals side by
side ('1st|2nd', '3rd|4th' -- why 4 bitmaps serve 8 players);
draw = texture rank/2 with a u-half selected by rank parity
- alpha-blended A4R4G4B4 white-on-transparent textures x green
diffuse = the authentic green look
BT_SHOT moved AFTER the 2D pass -- it captured the backbuffer pre-HUD,
so overlays were on screen but invisible to screenshots (cost one
false debugging round). GetOrdinalTexture accessor added.
Screenshot-verified: '1st MAVERICK' standings + MAVERICK banner over
live auto-directed coverage; 2-node mech smoke PASS (un-regressed;
the new render path only executes when a CameraDirector HUD exists).

The spectator/broadcast seat works end-to-end: a hostType=1 +
vehicle=camera pilot page boots a CameraShip whose 62-camera arena1
network loads from the BTL4.RES type-27 resource (the engine's
CreateStreamedCameraInstances existed all along -- the file probe falls
back to it), the BTCameraDirector locks onto the first live mech, and
the ship TRACKS it (sees=1, goal advancing) and CUTS between authored
camera positions (screenshot-verified: wide arena shot -> close
tracking shot).
The missing piece was the Mech override of PlayerLinkMessageHandler
(@0049f624), which the reconstruction never filled. The engine base
resolves mech->player; BT's override adds:
1. the REVERSE link player->playerVehicle = this on EVERY node
(replicants included) -- how the camera director and scoreboard
find a REMOTE player's mech; without it a spectator parks forever
('NO goal entity')
2. clears NonScoringPlayerFlag (0x4000 = bit 14): a pilot with a
vehicle is a SCORING player -- this admits REPLICATED players to
the ranking pass, so cross-node rank/score displays work
3. master only: seeds the heat bank's ambientTemperature (bank
@0x1d4) from the mission [mission] temperature= (BTMission+0xf4)
-- correcting the heat family's 'frozen 300' deviation note (it
was never frozen; THIS is the writer)
Bridge BTSetBankAmbientTemperature lives in heatfamily_reslice.cpp
(mech.cpp cannot include subsystem headers -- local-stub collision).
BT_CAM_LOG diagnostics: camera-network count, director pick + Players
group census, ship follow state, link dispatch/receive.
Verified live: 2-seat (mech + camera) relay session -- replicated
player shows +veh, director goal locked w/ 30s timer, ship tracking a
moving mech through camera cuts; standard 2-node mech smoke PASS
(un-regressed). Lesson re-learned: a 'clean' build filtered on 'error
C' missed a linker file-lock failure -- one whole test cycle ran
against a stale exe (the /FORCE gotcha's cousin; grep -i error, not
error C).
Remaining (task open): ranking-window overlay draw (L4VIDRND stubs),
operator-app camera-seat row, shot polish.

The 'cameras\ directory missing, ask Nick' entry (a03b16f, same day)
was WRONG: the file path is only the DEV OVERRIDE (the RP-style loose
.CAM files -- present for RP in the nick-games 410SRC archive, which
prompted the re-check). The shipped binary falls back to a BTL4.RES
resource TYPE 27 (0x1b) named after the map (FUN_0042be3c probe ->
FUN_0042c078 res loader; per-cam binary records, parsers @0042ad54/
@0042b9f8) -- and our res has ALL 8 maps' networks (arena1 = 62
cameras; cavern/dbase/grass ~57KB each). First arena1 record parses
clean (pos+quat, type 2).
The spectator/broadcast seat needs no external data: remaining work is
the type-27 loader in the WinTesla CAMMGR (file flavor only today),
the stubbed ranking-window draw, and a camera-vehicle boot test.

The CameraShip spectator system is engine-complete (CameraDirector
auto-follows the score leader, CAMSHIP cuts between fixed map camera
positions like TV coverage, ranking window flashes 10s/15s + final
30s), but the per-map cameras\<mapname> notation files are absent from
the archive -- added to the get-from-Nick list with the reconstruction
alternatives (author our own / chase-cam fallback) and the two code
gaps (stubbed ranking-window draw, camera vehicle never boot-tested).

Byte-decoded finding [T1]: the gait SM has no stable state for a demand in
(walkStrideLength@0x534, reverseSpeedMax@0x538). Cap semantics settled from
LoadLocomotionClips @0x4a80d4: 0x538 is the walk->run TRANSITION CLIP's exit
speed (the run ENGAGE threshold -- not a reverse max) and 0x34c (run-cycle avg
root speed) is the mapper's continuous demand multiplier (FUN_004afd10). The
finished-callbacks up-shift when tgt > 0x534 but enter/sustain run only when
tgt >= 0x538, so a demand parked between them (Blackhawk: 22.02-30.87 =
throttle 36-50%) hunts walk -> shift-up -> shift-down forever, firing the
authored EngineShiftFwd/Rev sounds each swing -- the user's repro, faithfully
reproduced by all-authentic logic + data. Likely masked on the pod by
MECHANICAL throttle-quadrant detents ("5 speeds" lore; the software path is
notch-free) [T4] -- added to get-from-Nick.
Accommodation (keyboard = our stand-in lever): at key REST, snap the lever to
the nearer dead-band edge (walk cap, or run engage + margin since the cont
check is >=). Sweeping THROUGH the band while held stays continuous -- an
authentic moving lever; the single shift it fires is the authentic shift.

Went after the flagged ~2.9u peer-motion snap. Added a BT_SNAPLOG diagnostic
(mech4.cpp: logs the re-anchor drift eMag = |authority - dead-reckon| absorbed per
frame) and ran a controlled accel/decel soak: node B BT_AUTODRIVE + BT_DRIVE_SWEEP0
sweeping the throttle through STOP, node A observing, affinity-pinned.
Result: peer drift maxes at ~0.64u (median 0.54u, 18 events >0.5u over 48s), gently
absorbed at k~0.24/frame -- SUB-UNIT, at the noise floor. The ~2.9u figure was stale:
it predated the peer body-channel swap (96a896a, which put the peer on the same
channel the master's mirror predicts) AND was measured without the CPU-affinity fix
(packet-jitter-sparse records inflate the drift). The old "run the master mirror on a
leg-channel prediction" plan is moot now the peer is on the body channel.
No motion-code change -- just the measurement + the BT_SNAPLOG diagnostic (retained).
KB (multiplayer.md, open-questions.md) corrected to the measured value. checkctx CLEAN.

Investigated the "console death froze peer replication" open question (2026-07-14)
with a direct 2-node repro (BT_REPL_LOG on a circling peer, affinity-pinned):
- Clean relay kill -> replicant kept circling smoothly through the kill, NO
disconnect logged, node survived. Replication did NOT freeze.
- Deliberately STUCK console (scratchpad/btconsole_stuck.py: connect, start
mission, then stop recv() while holding the socket OPEN = the exact
"receive pad full -> close never seen" mode hypothesized) -> replicant kept
moving the whole run. Replication did NOT freeze.
Conclusion: peer replication is INDEPENDENT of the console (pods replicate
peer-to-peer over the GAME socket; the console is a separate egg/mission/status
channel). The original freeze was a transient -- plausibly the same single-box
packet-jitter/CPU-contention artifact root-caused in 49d73dc -- or was fixed by
later MP work.
FIX (the one real bug found): L4NetworkManager::HostDisconnectedMessageHandler's
ConsoleHostType branch closed gameListenerSocket (the GAME listener) on a CONSOLE
disconnect -- a naming bug (the comment + commented-out OpenConnection intended a
CONSOLE re-listen, which CreateConsoleHost already does). Removed. Harmless to
established peer sockets (why a live match survives console loss) but it would
have blocked a NEW peer from joining after a console cycle. Verified: 2-node
still connects (All connections completed!) + the peer circles.

The open-questions.md block was the old completion PLAN (ea39af1) and was never
updated after the work actually landed + the residual was root-caused. It
contradicted multiplayer.md (which correctly documents both "Authentic coupled
peer motion -- DONE" and the packet-jitter resolution). Reconciled to DONE:
coupled single-source gait pipeline default-on (c52a1ad/b013742/96a896a/f094d78/
23f1532); the "needs master half" conclusion superseded by 49d73dc (residual
shakiness = single-box packet jitter, a test-rig artifact, fixed with CPU
affinity, user-confirmed -- NOT a game bug). Minor follow-ups (2.9u channel-snap,
decay constant) tracked in multiplayer.md. No code change -- KB currency only.

The boresight's non-mech pick only sampled the VISUAL heightfield (BTGroundRayHit),
which on arena1 is a single flat 'sky'-named ground mesh (and class-42 BuildTables
likewise holds only 'sky') -- so shots passed THROUGH the garages/walls and only mechs
moved the HUD range axis (user-reported regression: "buildings used to move the range
axis; now only mechs do, and you can only fire at a peer").
Real fix: the boresight now ALSO ray-tests the ZONE'S STATIC COLLISION SOLID TREE --
the same geometry that already blocks the mech's walk. Authentic engine mechanism:
Mover::FindBoxedSolidHitBy already tests the static world via
zone->GetCollisionRoot()->FindBoundingBoxHitBy(line). Factored its "static world" tail
into Mover::FindStaticSolidHitBy(Line*) (static solids only, no movers), wrapped by
Mech::WorldStructurePick(start,dir,range,&hit) (builds the world-space Line, reads the
entry point back via line->FindEnd since HitByBounded clips line->length=enter).
Boresight pick order is now: closest MECH (PickRayHit, damage zones + lock) -> closest
STRUCTURE (WorldStructurePick; occludes a mech BEHIND it; designates the gBTTerrainEntity
sentinel + entry point, so the range caret reads the structure distance and NO lock ring
draws, mech4.cpp:4529) -> flat ground (BTGroundRayHit) -> sky (fire-at-nothing). Also
un-skips arena1's misnamed-'sky' flat ground so the ground tier works (btvisgnd
geometry-aware skip + [mapent]/[rendent] census).
Verified headless: a BT_WSWEEP horizontal ray-fan on arena1 tracks position (3/24 hits
near the boundary -> 17-21/24 inside the interior garage cluster -> 3/24 past it =
DISCRETE interior solids, not an enclosing box), no crash/assert/AV. Interactive aim
(BTGetAimRay) can't run headless (no window -> noRay), so the sweep is the headless proof;
interactive aim is user-verified.
Note: FindBoundingBoxUnder (the ground/containedByNode BoundingBoxTree) is DOWNWARD-only
(gravity/ground-snap: *height = FindDistanceBelowBounded), useless for a horizontal
boresight; the static SOLID tree's FindBoundingBoxHitBy is the only ray-vs-world query.

Reproduced the QA report end-to-end from the decomp + raw-binary-verified constants.
The coolant-priority effect is real but fire-rate-dependent: at the ~11s combat
cadence, not-boosted jams (T=1058>1000) while boosting the AFC's condenser keeps it
below the line (T=953, no jam) -- exactly as the QA described. Max-spam (8s) overheats
regardless (why the earlier 'weak boost' read was wrong); 16s never jams. All AFC100
constants verified authentic vs BTL4.RES raw bytes (afc_dump.py). No bug, no stand-in.

Two-agent decomp hunt on the QA report ('AFCs jam on 3rd shot if coolant priority
not boosted'). Conclusion: the whole coolant->jam chain is reconstructed end-to-end
and FAITHFUL -- the weapon's constant coolantFlowScale=1.0 is authentic (only
condensers' 0x15C is written from the valve, via RecomputeCondenserValves over the
condenser chain mech+0x7cc). Authentic mechanism is second-order-in-equation but
first-order-in-outcome: weapon -> its condenser -> bank; boosting a condenser's valve
share (~5x conductance swing) keeps its weapon below degradationTemp -> no jam.
Distinguished the sticky probabilistic jam (degrad 1000, JammedState 5) from the
self-clearing overheat lockout (failure 2000, weaponAlarm 7). Empirically the port is
directionally correct (~4th-shot probabilistic) but not the QA's deterministic 3rd
shot -- a calibration/scenario question pending QA clarification, NOT a stubbed path.
Do not tune the heat economy to force it without ground-truth.

Reverting a wrong 'correction' I just made: I claimed the six L4VIDRND explosion
renderables were STUBBED and 'never draw'. WRONG -- ScalingExplosionRenderable has a
real ctor/Execute body, and the impact/fire/detonation FX were reconstructed in the
Fire VISUALS (48c9c84) + Impact-FX FORENSICS (065c114) waves. The '//STUBBED: DPL RB'
markers I grepped are benign 2007 empty ctor/dtor notes on unrelated renderables
(InnerProjectile/DPLObjectWrapper/ChildLight), not the explosion FX. Only genuine
open item: the chain is not yet liveness-verified headlessly (no solo enemy).

Investigation (workflow) found the searchlight-driven fog swap never worked in the
ORIGINAL 1995 binary either -- it's a latent bug, not a port regression:
SearchlightSimulation (@004b841c) reads requestedOn@0x1E0 (never written) while
ToggleLamp (@004b860c) toggles commandedOn@0x1DC; no bridge exists, so lightState
@0x1D8 is perpetually 0 (lamp never lights). The self-consistent sibling
ThermalSight reads the field it toggles (0x1DC) -- the tell. The port reproduces
the bug faithfully (searchlight.cpp:189). Additionally the port never constructs
PullFogRenderable, so even absent the bug the swap wouldn't fire.
Decision: LEAVE AS-IS + document (faithful to the buggy original); the port keeps
the static lights-ON fog= values. A working swap would DEVIATE from the shipped
binary (repair the sim to read commandedOn + construct PullFogRenderable at the
btl4vid MakeMechRenderables inside pass + a toggle input) -- fully scoped in the KB
if ever wanted. No code change this commit.
Documented in rendering.md (fog section), open-questions.md (deferred subsystems),
subsystems.md (Searchlight). Core per-map/time/weather fog (task #63) is unaffected.

Area-of-effect blast on missile detonation, from the T0 source EXPLODE.cpp:50-254
(@0042fad0) + the arcade decomp. Fires on ANY missile impact (world or mech) --
the +0x360 gate sits in the Missile::Perform collision branch (part_013.c:10097).
Only missiles splash; the AC's tracer is not a Missile.
Radius source CORRECTED: it is the ROUND's own GameModel (type-0xf) +0x50, seeded
from the launcher's linked AmmoBin ammoModelFile @0x1e8 (part_013.c:8778) -- NOT
the launcher's ExplosionModelFile (which resolved to 0). Live-resolved radius = 30
for both MP missile launchers; 0 for AC/Emitters.
Burst falloff = baseBurst / dist^exp floored at 1 (arcade 1.25 = decomp 0x3ff40000;
WinTesla EXPLODE.cpp:209 drifted to 1.2f). damageType/amount pass through unchanged;
only burstCount, radial damageForce, and impactPoint are set. Excludes shooter +

Deferred (T3): per-player enable sub-gate missile+0x360 = BTPlayer+0x264 (writers

The autocannon gains its authentic muzzle effect AND becomes visible when an
enemy fires it -- the ballistic-FX gap behind "I only see the AC from my own
view."
MUZZLE FLASH (the genuine shipped effect, not the cut card):
- MUZFLASH.BGF is an orphaned/cut asset (nothing references it) -- so it is NOT
rendered. The shipped projectile-gun muzzle effect is DAFC.PFX, which
BTDPL.INI documents as "the effect used on all projectile guns" (psfx 6
external / 14 internal): an orange fire-smoke blast (btfx:firesmoke1),
maxIssue 25 over ~0.2s so the emitter auto-expires = one burst per shot.
- BTFlashMuzzle (mech4.cpp) spawns it on the gun-port SEGMENT via the existing
BTStartPfxAttached path; the segment frame sprays -Z out the barrel. Hooked
at ProjectileWeapon::FireWeapon (the fire edge). Default ON (BT_MUZZLE=0
disables). AC only -- lasers show their beam, missiles their launch.
ENEMY AC FIRE NOW REPLICATES (the real find):
- ROOT CAUSE: the subsystem-record replication channel EXISTS and works (mech
ticks subsystem->PerformAndWatch(update_stream); Entity::UpdateMessageHandler
routes incoming records to GetSimulation(subsystemID-1)->ReadUpdateRecord).
The emitter (beam) and MissileLauncher (salvo mirror) both call ForceUpdate()
so their fire serializes -> enemy lasers + missiles ARE visible on the peer.
The AUTOCANNON set only `simulationFlags |= 0x1` (the +0x28 instance flag,
NOT the updateModel bit WriteSimulationUpdate walks) and had NO fire record,
so its shot never crossed the wire -- the enemy's cannon was invisible.
- FIX (the AC twin of the missile salvo mirror): ProjectileWeapon::
WriteUpdateRecord/ReadUpdateRecord (fire counter + aim) + ForceUpdate() in
FireWeapon. The replicant edge-detects the counter and mirrors ONE visual
round + DAFC muzzle flash from its own resolved muzzle; a null/untargeted aim
streaks straight out the barrel (launchVelocity) instead of toward origin.
- Verified live 2-node: the watching node logs REPLICANT AC shots + DAFC
flashes at the enemy's gun-port (seg 7), aimed shots fly to the real target;
no crashes.
TRACER: all ACs author TracerInterval=1 (every round is a tracer); the existing
amber streak is acceptable-authentic, so no tracer change was needed.
KB: open-questions.md -- CORRECTED the (wrong) earlier note that claimed no
subsystem-record channel exists; it does, the AC just wasn't using it. Logged
the methodology lesson: the coverage audit finds UNWRITTEN functions, not
"reconstructed but inert" ones (a function present but never called -- the AC
record + the missile mirror both looked done); a LIVENESS audit would catch
that class.

Full 5-path audit of the damage economy vs the decomp (5-finder +
adversarial-verify workflow), resolving the KB self-contradiction the
binary-coverage audit flagged.
CONFIRMED AUTHENTIC as-is (no change needed):
- Energy beam (emitter.cpp): damagePortion = authored DamageAmount x
(charge/seekV)^2; the ctor x1e7 and fire x1e-7 cancel (_DAT_004bafbc
dumped from the exe = x87 80-bit 1e-7 exactly).
- Autocannon (projweap.cpp): full authored DamageAmount from resource
+0x19C delivered unmodified; the 0.0625 at :667 is the shooter's own
gyro recoil, not the round.
- Zone-armor BASE model: damageLevel += amount x damageScale[type]
(engine DAMAGE.cpp:379, called mechdmg.cpp:427), legs x0.5, 1.0=dead.
3 STAND-INS FIXED (all byte-verified against the decomp):
- A. mechdmg.cpp:451 -- read the phantom `stance` member (no binary
offset, zero writers -> perma-0), so the leg-shot-out -> fall/death
branch was DEAD. Now MovementMode() (mech+0x40, @part_012.c:6910).
- B. mechdmg.cpp:458 -- guarded the leg partial-failure graphic on the
always-0 IsAirborne() stub where the binary calls IsDisabled()
(@0049fb54 = movementMode 2||9). On a wreck the binary SUPPRESSES the
write; the stub let it corrupt graphicAlarm 9->4/3 -- the task-#52
wreck-graphic bug, now fixed AT SOURCE (was only masked by the
IsMechDestroyed latch).
- C. mech4.cpp:1551 -- flat kShotDamage=12 fed as the kill-score
damageAmount (the KB self-contradiction: task #8 claimed it retired,
but it was live). The score handler @0x4c02e4 derives the whole kill
award from it, so every kill scored identically regardless of weapon.
Now lastInflictingDamage -- the real killing-blow magnitude, latched
in TakeDamageMessageHandler (mech.cpp:624), mirroring the per-hit path
(mech4.cpp:1207). The phantom `int stance` slot is reused for the new
Scalar member (size-neutral, no layout shift); init 0 in the ctor.
DEFERRED (task #60-D, documented): the missile CLUSTER model -- the port
fires N flying rounds (net armor total authentic) vs the binary's ONE
missile with a random burstCount cluster roll (loses cluster variance +
single-zone concentration). Blocked on an OPEN decomp semantic (does
burstCount multiply armor or only the gyro kick? settle at FUN_004bef78
-> FUN_004be078 -> EXPLODE.cpp:209-210).
VERIFIED live: clean build; 2-node fight -> clean center-mass kill (no
crash, kills 0->1); [zone-armor] dump confirms per-zone armor 50-140 +
legs x0.5. NB the displayed POINTS score still reads 0 -- a SEPARATE
open gap (scoreAward + role/team/tonnage multipliers unwired); fix C
corrected the damage INPUT to that formula.
KB swept: open-questions.md (self-contradiction resolved + task #60
summary + deferred missile item), combat-damage.md (damageScale is
type-indexed not even/odd; task-#52 source fix; kill-score section),
RECONCILE.md (missile = ONE spawn not N), stale comments in mechweap.cpp
(SendDamageMessage is LIVE), mislanch.hpp, mechdmg.cpp (FUN_0049fb54 =
IsDisabled).

The MadCat (and every leg-mech) leans -8deg into a walk / -11deg into a run --
an authored jointhip (hingex) pose in the EXTERIOR gait clips that the walk/run
CYCLE clips never rebind, so it HOLDS. The 1995 game keeps a separate INTERIOR
('i'-suffix) clip set for the mech you PILOT: those shake jointshakey (cockpit
rattle) and OMIT jointhip, so your own view stays level while everyone else sees
you lean. The port had this entirely dead -- the local cockpit mech pitched
-8deg into the ground (user-reported "staring at the ground").
ROOT CAUSE (two stacked bugs):
- The authentic ctor clip-set gate (@part_012.c:10308-10320) was reconstructed
as no-op stubs: LoadLowDetailBody/LoadHighDetailBody MISLABELED the
FUN_004a80d4/86c8 GAIT-CLIP loader addresses as a "body LOD" pair, so the gate
did nothing and a separate unconditional LoadLocomotionClips always loaded
EXTERIOR clips.
- LoadLocomotionClipsExt (the interior loader) was a stub aliased to the
exterior loader.
FIX:
- Reconstructed the real 4-char INTERIOR loader (byte-exact vs @004a86c8; the
'i'-suffix table dumped from the exe @0x10d74d: swri/wwri/wwli/...; all 18
base clips confirmed present in BTL4.RES for mad/blh/ava).
- Fixed the ctor gate: getenv("L4VIEWEXT") || (instanceFlags&0xC)==4 -> exterior
(replicant / forced external view); else -> interior (local cockpit master).
Removed the mislabeling no-op stubs.
- PORT ADAPTATION (MaintainViewClipSet, per-frame in PerformAndWatch): the port
never sets the replicant COPY bit (all MP mechs build as local masters --
heat-sim/scoring/torso-watcher-connect all run on both, by design), so the
ctor gate lands everyone on interior. Pick the set by VIEWPOINT instead: the
mech you pilot keeps interior (level cockpit), every other mech flips once to
exterior (the lean). Reloads only on a viewpoint-status change; the sets
share stride data so the swap is seamless. Model pointers stashed at ctor.
VERIFIED live (BT_HIP_LOG probe): your walking mech writes jointhip=0 (level);
the peer's replica in the other pod's view leans at exactly -8.0/-11.1deg --
the authored clip values. A/B control: L4VIEWEXT=1 forces the walking master
back to 74 sustained -8/-11 writes.
KB: locomotion.md ("NO walk lean" audit conclusion CORRECTED -- the lean is
authored + sustained + clip-set-specific), asset-formats.md (.ANI parses
pitch/yaw/roll for all joint types; KeyJointPos translation; cycle clips carry
no pitch), open-questions.md (item closed).

The MadCat torso twists, the view turns with it, and targeting follows.
Three reconstruction fronts closed:
THE ELECTRICAL WATCHDOG CHAIN (why the torso never powered up):
- PowerWatcher::UpdateWatch reconstructed (@004b181c, the REAL registered
Performance -- PTR @0050f5fc; Ghidra missed the fn start): the watchdog
MIRRORS the watched subsystem's electrical level (+0x278), brownout
downgrade when gen output <= minVoltage% x rated. @004b1804 relabeled
ResetToInitialState (slot 10) -- the old "Simulation" tag was wrong.
- The factory watcher-CONNECT pass reconstructed (vtable slot +0x38,
@004aee2c/@004b1a40 byte-identical, recovered from raw exe bytes):
watchedLink.Add(roster[watchedSubsystem]) on the master node. Was the
SubProxy::Start() no-op -- every watchdog sat at 0 forever.
- MinVoltageScale = 0.01 (a 10-byte x87 literal @0x4b1924; was 1.0f =
permanent brownout) and PowerWatcher's Derivation chains its REAL base
HeatWatcher (the HeatableSubsystem stand-in broke IsDerivedFrom for the
whole Torso/Searchlight/ThermalSight family).
- KB correction swept: derivation tag 0x50e604 = HEATWATCHER (not
"HeatSink"); the btl4gaug heat-widget gate now tests it via the
BTIsHeatWatcher bridge.
THE CROSSHAIR (task #58 forensics, 6-agent workflow + live probes):
- The VIEW is TORSO-MOUNTED: jointtorso -> jointeye -> siteeyepoint in
every twist-capable .SKL; the camera + canopy ride the same hinge
subtree through HingeRenderable's live matrix-stack compose -- ALREADY
WORKING in the port. The crosshair stays screen-centered (center IS
the boresight); the twist reads on the tape carets/compass/radar.
- The real bug was the port's gBTAimX = tan(twist) slew (the falsified
"body-mounted view" model): the camera already carried the twist, so
the crosshair counter-slid to hull-forward and the fire ray with it.
Deleted; the pick ray inherits the twist from the yawing eye basis.
- Two instrumentation traps documented (chase-eye-as-default-camera,
BT_FORCE_TORSO clobbering real joints -> the hook now only fills
unresolved ones); an over-correcting explicit eye compose was added on
those false readings and retired the same day.
CONTROLS + REPLICATION:
- Q/E spring-center on release (the axis is a twist-RATE demand; the old
hold-deflection model drifted forever); X also zeroes the axis and
pulses the authentic torso Recenter (@004b6918). M cycles control
mode via the real CycleControlMode body.
- Torso update-record DIRECTION fixed: engine truth is Write=serialize /
Read=apply; @004b6a78 is the READ (was mislabeled Write) and the
missing WRITE @004b6a1c recovered from raw disasm (recordLength 0x1C,
twist/vel/rate at +0x10/14/18) -- kills the replicant's 0xCDCDCDCD
-140-degree ghost twist.
- Marching-ghost desync: 4 Standing-case guards zero stale reverse
cycleSpeed (negative cadence passed the <= ZeroSpeed stop gate).
- Kill credit rerouted to the OBSERVED killer (lastInflictingID ->
killer's player link) -- kills count, target K/D populates.
KB: subsystems.md (watcher chain), multiplayer.md (record direction),
combat-damage.md + gauges-hud.md + cockpit-view.md (torso-mounted view
re-correction), decomp-reference.md (new addresses + tag fix),
open-questions.md (dead capability-roster loops 2-4, snapshot CD read).

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).

The pilot's second heat-management tool: the PoweredSubsystem message table
@0x50F4EC (ids 4-8) registered and implemented -- SelectGeneratorA-D
(@004b099c..@004b0a74: FindGeneratorByNumber roster walk on generatorNumber
@0x1E0 -> AttachToVoltageSource re-tap with tap accounting -> modeAlarm
Connected) and ToggleGeneratorMode (@004b0abc: Manual -> Auto -> detach+Manual
cycle). Weapons inherit via the MechWeapon handler chain. Desktop: F5-F8
assign the selected weapon (BT_CONFIG_SLOT) to Generator A-D, F9 toggles
reconnect mode; BT_GENSEL_TEST scripts a headless verify.
Verified live end-to-end: dispatch -> handler -> re-tap ("PPC_1 ->
GeneratorD (tapped)") -> the charging I^2R physically moved (GenD cold ~90K
baseline -> ~1570K carrying the PPC; GenA relieved), stable over a sustained
autofire soak with thermal-breaker trips.
FOUR defects found and fixed on the way [all T1/T2]:
- THE e17 HEAT EXPLOSION: Generator::SourceLevel misread *(this[0x38]+0x158)
as linkedSinks->heatEnergy; it is the engine-base DamageZone @0xE0 ->
damageLevel [0..1] (the same named-member pattern as the bank radiator's
zone read). A breaker-restarting generator emitted (1 - 4e8) x 10000
volts; squared through the customers' I^2R feed, one restart blew the
whole thermal network to e17. Authentic: a damaged generator yields
proportionally less voltage.
- FUN_004ac9c8 is NOT "IsDamaged": raw body = owner -> mech+0x190 player ->
roleClassIndex(+0x274) == 0 -- the ROOKIE-role lockout for advanced
cockpit systems. New bridge BTPlayerRoleLocksAdvanced (NULL player =
unlocked [T3]; bring-up role 2 = unlocked). The old stand-in gated the
handlers off permanently (healthy subsystems have simulationState==1).
- MESSAGE_ENTRY tables must be FUNCTION-LOCAL statics inside the accessor:
as namespace-scope arrays they are read by other TUs' static-init chains
before their own initializers run -- Build copies zeros and every id in
the table is silently dropped (ids 9/10 only worked by TU-order luck;
both tables relocated; gotcha recorded, reconstruction-gotchas #9).
- The AutoConnect hunt scanned GetSegment() -- the raw @004b0bd0 walks the
subsystem ROSTER (+0x124/+0x128); EntitySegments were being cast to
Subsystems (the classic +0x128 gotcha).
Also: the dense handler table's GAP slots (skipped ids) are uninitialized
heap -- the name-based Find strcmp-walks them and AVs; diagnostic probes use
the id-based Find only (the 1995 binary's own tables carry the same holes).

TASK #6 -- the pod's in-cockpit weapon regrouping, fully reconstructed and
live-verified (hold-configure -> tap fire button -> toggle membership ->
release-commit):
- MechWeapon handlers id 9 ConfigureMappables @004b9550 / id 10 ChooseButton
@004b95b8 (binary table @0x511860; the old "Myomers fns" mislabel swept)
+ the GetMessageHandlers() accessor chain through Emitter/ProjectileWeapon/
MissileLauncher/GAUSS/PPC (empty per-class sets swallowed dispatch).
- Mapper vtable truth: +0x38 EnterConfiguration / +0x3C ExitConfiguration /
+0x40,+0x44 AddOrErase evt/dir. No "secondary vtable @0050f498", no
"CreateTemporaryEventMappings" virtual (RP-name drift; swept incl CLASSMAP).
L4 Enter/Exit rebuilt complete: StartMappableButtonsConfigure (the
NonMapping 0x10000 <-> Mapping 0x8000 mode flip + the gauge's active-weapon
latch) + the held-button re-arm + the 4 fire-button temp maps; only the RIO
mapper implements the toggle (Thrustmaster no-ops = can't regroup).
- MechSubsystem +0xE8/+0xEC corrected to controlDestination/controlMessageID
(ex hostEntity/subsystemId2 mislabel); MechWeapon ctor defaults the
destination to &fireImpulse (@004b99a8).
- ConfigMapGauge state loop reconstructed (PE-recovered DAT_00518eb4 table;
buttonGroup GetMapState sampler -- the "needs ModeManager" guard rationale
was wrong). Finding [T1]: the shipped binary NEVER enables this gauge (no
SetColor caller) -- authentically dormant; BT_CONFIGMAP=1 is the dev enable.
- Dev harness: HOLD 'G' opens the session (BT_CONFIG_SLOT picks the weapon);
BT_CONFIG_TEST scripts a headless verify. @004afbc4 corrected to its real
Fail-trap body (the guessed AddOrErase(NULL) body would corrupt groups).
- Bonus [T1]: the binary MechWeapon ATTRIBUTE table has ELEVEN entries
(PercentDone..WeaponState) -- "TriggerState is the only one" was wrong.
TASK #11 -- the user-reported live-play regressions (both real bugs):
- PHANTOM FIRE: the mech4 bring-up shot block painted an explosion at the
victim on its OWN 0.3s cadence whenever fire was held -- desynced once the
authentic recharges landed. Retired (the real impact visual flows from
each discharge via the messmgr SubmitExplosion).
- WEAPON BRICKING (the "cuts out" bug): the Loading->Loaded snap window
(+-0.01 around seekV) assumes the pod's LOCKED 60 fps; one port dt-spike
jumps it, the byte-verified >1.0 clamp (_DAT_004ba830=0) zeroes readiness,
and the weapon sticks in Loading at level ~10000 forever (observed live).
Fixed with pod-frame (1/60s) sub-stepping of the binary's own Loading tick
-- also fixes the I^2R integral over-heating generators on big steps.
NEW GOTCHA CLASS recorded: reconstruction-gotchas #12 (frame-pacing trap).
- Duty-cycle measured (max-rate autofire): generators equilibrate in the
degradation band (recharge stretch ~3.5-4.4x), the FailureHeat breaker
never trips solo, PPCs sustain ~11.8-damage full-charge fire. The slow
kill pacing and recharge gaps are the AUTHENTIC heat economy; the pilot's
counters (this regrouping UI, generator reassignment, coolant valves) are
the reconstruction queue.

Task #10 set out to fix "scrambled linked-sink routing"; a [heat-link] attach
log proved the routing was NEVER scrambled (every subsystem links its authored
condenser exactly; the "pools in Condenser1" read was the diagnostic-sampler
aliasing trap). The real defect: emitter.cpp's local FUN_00417ab4 stub
returned NULL, so the whole electrical model was inert and the E7 force-charge
recharged every emitter in ONE frame (~0.3s cycle, 1501 fires/90s, ~1.7e9
heat/s -- the "runaway").
Landed authentically [T1: disasm + byte-verified constants]:
- Emitter ctor @004bb120: seekVoltage = authored fraction x generator
ratedVoltage (10000); EC = energyTotal/(seekV^2 x 0.5); voltageScale@0x310 =
(RechargeRate / -ln(1 - 1e-4 x seekV)) / EC -- charge reaches seekV[rec] in
EXACTLY the authored RechargeRate (PPC 5s, ERL 4s, SRM 3s, ERM 2s) cold.
Owner-flags ctor gate (the usual gotcha; the this-flags read never armed).
- PoweredSubsystem::ChargeTimeScale (@004b0d50, was a =1.0 stub): voltageScale
x (1 + thermalResistivity x srcTempRise) -- hot generators charge slower.
("voltageScale is never read back" was wrong; corrected + swept.)
- TrackSeekVoltage @004ba838: charging I^2R -> the GENERATOR's pendingHeat
(~3.5e8/full PPC charge) -- generators self-heat, conduct to their authored
condensers, and throttle further charging. The feedback economy closes.
- FailureHeat consumers found: this+0x184 == 2 gates BOTH weapon families
(@004baa88 emitter: reset firing + hold charge 0; @004bbd36 ballistic:
recoil=rechargeRate + alarm 7). Emitter::GetFaultState un-stubbed.
- ProjectileWeaponSimulation @004bbd04 opens with call 0x4b0bd0 (disasm) --
launchers now run the powered/heat step (their firing heat previously
accumulated in pendingHeat forever).
- heat.cpp: per-instance BT_HEAT_LOG census (the old shared-static 1-Hz
sampler aliased); [heat-link] attach log; the stolen-else Verify restored.
Verified live (120s max-rate autofire): PPC ~470-500 (was 55,000), bank
plateaus ~600 and sheds to ambient, generators 1100-1400, ERMLaser
self-regulates at the authored 2000 failure threshold (shutdown-cool-resume).
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- Emitters: heatPortion closed form = heatCostToFire x 1e7 x (charge/seekV)^2
(PPC 1.1e8 -> +632K on its own sink); the missing projectile/missile heat
adds (raw -- resources author pre-scaled 1e7 units).
- The bank's AMBIENT RADIATOR @4ae73c reconstructed (the system's ONLY heat
exit; conductance x 0.1 x HeatSinkCount -- _DAT_004ae974 float80 = 0.1) +
the link-attach guard corrected (skip = the 0xBBE bank, not Condenser; the
inversion blocked condenser->bank links and closed the system).
- Constant corrections (all byte-verified float80s): coolant epsilons
0.0025/0.003/1e-4 (was a single 1e-4 serving three sites);
CoolantCapacityScale 0.05 (was 1.738).
- Verified: heat flows + exits; max-rate autofire overheats weapons into the
authentic heatLoad range-cutout (thermal spam unsustainable by design).
- KNOWN REMAINING: linked-sink routing scrambled (heat pools in Condenser1;
authored map says PPC->C4/C6) -- the heat-stream offset audit, filed.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Three root causes, all fixed:
1. kDamageScale was 1.0 -- _DAT_004bafbc is an x87 float80 = 1e-7, cancelling
the ctor's x1e7: damagePortion = authored DamageAmount x (charge/seekV)^2
(closed form at fire time; madcat AC=25/LRM=50/ERLL=6, bhk1 PPC=12/SRM=35).
The observed "0.25" was the degenerate EC=1 fallback, never authored data.
2. CheckFireEdge NaN latch: TriggerState carries ControlsButton INTS; the
release value (-65) is a negative NaN. The binary's x87 unordered compare
read it as "released"; IEEE-correct float compares latched the edge
detector shut after the first release -- the reason the emitter discharge
chain NEVER fired in-game. Fixed with bit-pattern sign compares.
3. The weapon-side submission LIVE: Emitter::FireWeapon fills damageData
(amount + damageForce=target-muzzle [the gyro directional-bounce feed] +
impact) -> MechWeapon::SendDamageMessage (@004b9728 real body) ->
messmgr consolidation with per-weapon records + explosion bundling.
The mech4 bring-up damage block + flat kShotDamage retired to diag hooks.
Bonus: LODReuseHysteresis 0.82 -> 0.33 (double misread). Zone model
verified byte-exact (no change). Solo end-to-end: 5-record volleys (2 PPC
+ 3 ERML with authored amounts), per-weapon zone granularity, explosions,
kill. Heat stays bring-up scale pending the heat-calibration audit [T3].
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
ConsolidateAndSendDamage @0049b784 fully implemented: the beam path submits
into AddDamageMessage; each messmgr tick builds ONE Entity::
TakeDamageStreamMessage (id 0x13; wire-verified 0x34+4+Nx12) with the
common impact record + appended {type, amount, subsystemID} entries and
Dispatches it at the victim -- the T0 handler (ENTITY.cpp:817) re-splits
into per-record TakeDamage; replicants reroute cross-pod. Real
ResolveExplosionID (firing weapon's +0x3E4, guarded) + SubmitExplosion via
the Explosion::Make port; TWO chain-purge bugs fixed (the "iterator dtor
clears it" assumption was wrong -- records re-applied every tick, observed
1->2->3->4 double-counting). @004b9728 identity corrected (SendDamageMessage,
not DrawWeaponPip). Verified solo: 25 clean single-record consolidations ->
kill -> death transition. Residue: weapon-side submission awaits the
damage-economy reconciliation (authored 0.25-scale vs kShotDamage=12).

The recovered system: fire channels = LBE4ControlsManager buttonGroups
(0x40/0x45/0x46/0x47); default groups = the per-mech type-6 controls-map
resource in BTL4.RES, installed by the T0 CreateStreamedMappings the port
already called -- it needed only the TriggerState attribute (id 0x13 PINNED
to the binary value; fireImpulse@0x31C is the binary's TriggerState) and an
input feed. Keyboard/harness now push press/release edges into the button
groups; the gBT*Trigger bypasses, per-type keyboard split and 1,0 pulse
hack are retired -- weapons sharing a button fire TOGETHER (madcat Trigger
= 4 weapons). Myomers @4b9550/@4b95b8 misattribution corrected (they are
MechWeapon ConfigureMappables/ChooseButton). Verified 2-node: kill through
the authentic chain (12 hits vs ~36 pre-groups). Config-mode session
(regrouping UI) = the remaining stage, KB-scoped.

The binding was in the zone ctor all along: Ghidra dropped the two arg
pushes @0049d0e1 (Slot::AddImplementation(subsystemArray[streamedIndex])),
making it read as a bare Resolve(). DZSlot stand-in -> engine SlotOf<T>;
SendSubsystemDamage rewritten to the recovered @0049c9a8 body (allotment
into the subsystem's OWN private zone; vital -> graphicAlarm 9); CriticalHit
-> real ApplyDamageAndMeasure; parentArtifactZone.Add revived (LOD damage
averaging); videoObjectFlag renamed vitalSubsystem (+0xE4). BT_CRIT_PROBE
diag added. Verified: 66 plugs bound/mech; probe-destroyed zone -> crits
damaged/DESTROYED, statusAlarm + destroyed-skin chain fire; MP kill + solo
un-regressed.

Resolved the non-Madcat blocked views. Rendering every *_COP shell offline
from its mech's AUTHORED eye (SKL [jointeye] translation -- incl. the Thor's
+1.13 offset cockpit) with faces coloured by punch flag showed the answer
plainly: the PUNCH-tagged patches sit exactly over the window apertures in
all 8 mechs. On these texture-less black-diffuse shells dpl_Punchize renders
the tagged geogroup as holes -- the punch patches are the transparent
WINDSHIELDS, and the visible frame is only the non-punch geometry.
The loader now drops the punch batches of _cop meshes (bgfload finish();
BT_COP_KEEPPUNCH=1 keeps them for diagnosis). In-game sweep on pure defaults:
- madcat: the dark dome frame (matches gameplay footage)
- thor / owens / sunder: authentic brace/dash/pillar remnants
- bhk1 / loki / vulture / avatar: authentically FRAMELESS (all-punch
canopies -- the pod showed no frame for those mechs)
(An early-session test that "disproved" drop-punch ran with the broken
pre-inverse eye; its conclusion was wrong and is corrected in the KB.)

Re-disassembled the unexported gap 0x4b2980-0x4b2d8b byte-exact (capstone over
section_dump.txt) and reconstructed Gyroscope::ApplyDamageResponse:
- zero-damage + Collision(type 0) no-op; hit direction = Damage::damageForce
or a RANDOM horizontal fallback when ~zero (per-component sign roll then
value roll -- binary-legal until senders fill damageForce)
- direction rotated by the yaw-only torso-twist frame (placeRot=(0,twist,0)
-> euler->matrix, the FUN_00408744 raw row-dot reproduced verbatim)
- per-type scaling amount / damageMultiplier[type] * damageResponse[type]
.{trans,pitchRoll,yaw,vibration}; Explosive alone multiplies burstCount;
each clamped at 1.3f
- four kicks: impulse(trans, dir), torque(pitchRoll, dir), impulse(vibration,
vibrationDirection@0x390) and verticalImpulse(yaw, dir)
Layout corrections (byte-verified): gyro+0x390 is ONE Vector3D vibration axis
init (0,1,0) -- was mis-split as scalars animationOffset/Scale/Phase; mech
+0x5c4 is a FLOAT rumble-period countdown (gyroRumbleTimer) -- was mis-typed
int clipLoadGuard.
Call sites wired (binary-gated):
- take-damage hub: mech.cpp TakeDamageMessageHandler, FIRST action (@0x4a0264
in hub FUN_004a0230) -- an invalid-zone hit still bounces
- crushable-icon crunch: mech4.cpp, torque 0.4 along the bounce delta-v + up
impulse 0.2 (@4aa81e/@4aa86c)
- firing recoil: projweap.cpp FireWeapon, damage>3 -> impulse (0,0.6,-1.5)
x damage/16 (@4bc136-4bc19c) via the new Mech::GetGyroSubsystem accessor
DEFERRED (recorded in KB with the byte recipe): the alternate-gait engage
jolt + 0.4s rumble (@4aa158-4aa365) -- its gates are [T3]-flagged and it
mutates the #49/#50-stabilized gait machine.
Verified live: [gyro-dmg] fires per hit with correct type scaling; eyePosition
shows the damped bounce (ramp to ~0.015u, oscillating Y, decay to zero); kill
chain un-regressed; no NaN.
Also recorded in KB: the OFFSET-COCKPIT verification -- Thor's authored
jointeye tranx=+1.13 matches its canopy X-center exactly AND our in-game eye
reproduces it to the hundredth (the placement model is correct per-mech); and
the playable roster is 8 models (strider/raptor/firstrtr/blkjack have assets
but no model resource -- BT_FORCE_MODEL with those names = NULL-resource AV,
cdb-verified, not a code bug).
