BT410 5.3.88: hinges flush as MATRICES -- the axis was never on the wire, and a DCS remembers how it was last set
The mech rendered with a live root and frozen limbs. Cause, and it is not in
the renderer:
L4VIDRND.CPP:1028 sets SINGLE_AXIS_HINGE True, so HingeRenderable pushes a
joint with dpl_SetDCSXAxis / YAxis / ZAxis -- three separate libDPL entry
points, each handed only (sine, cosine). The AXIS is carried by WHICH
FUNCTION WAS CALLED, and libDPL never puts it on the wire.
Confirmed against a live capture rather than argued: every articulation
record in joints_check.fifodump is 12 bytes, [handle][sin][cos], 26133 of
them, no axis field anywhere. And the renderer cannot recover it from
context either -- that capture contains ZERO action-0x22 name records, so a
DCS handle cannot be matched back to a .SKL node. vrboard was parsing those
records correctly and dropping them on purpose, with a comment saying so.
THE FIX is the archive's own alternative. The #else half of that same #if
(L4VIDRND.CPP:1153) builds a Quaternion from the Hinge and assigns it over
the DCS matrix -- the axis ends up IN the matrix, and it flushes as a
12-float pose the renderer already applies. That is precisely what
BallJointRenderable::Execute does unconditionally, with no #if at all, which
is why ball joints were never affected. So this is the branch the original
authors wrote and did not take, applied to hinges so they behave like the
ball joints beside them.
A DCS REMEMBERS HOW IT WAS LAST SET -- the part that cost a build.
The first attempt subclassed HingeRenderable and overrode only Execute. It
compiled, ran, and did not work: the wire still carried 12-byte records. What
it DID change was their contents -- the pair went from (sin, cos) to
(0.9990, 0.0000), which is m00 and m01 of the matrix being written. That is
the whole diagnosis in one number. The base ctor calls dpl_SetDCS?Axis before
the subclass gets control, which puts the DCS in single-axis mode, and the
flush then serialises two floats out of it no matter what goes in through
dpl_GetDCSMatrix.
So the axis setter must never touch this DCS. BTL4HingeRenderable therefore
derives from ChildOffsetRenderable, whose ctor builds the offset DCS and calls
no axis setter -- making it the exact hinge analogue of BallJointRenderable:
same base, holds its own attribute pointer plus a previous-value copy, writes
a full matrix in Execute. CODE/ untouched; Component::Execute is virtual
(CMPNNT.HPP:40) so the override dispatches normally, and shadowing 1900 lines
of L4VIDRND.CPP to flip one #define was not needed.
VERIFIED on the rig, torso-sweep conf, clean run:
before 26133 records, ALL 2-float, 1 handle, renderer applied NOTHING
after 7626 records, ALL 12-float, ZERO 2-float messages remaining,
22 handles emitted, renderer applied all 22 (anim_abs)
and the swept joint moves: handle 0x684, m00 across 1532 distinct values
from 0.1582 to 1.0000 -- cos of a 0..80 degree sweep, which is exactly what
BT_FORCE_TORSO drives.
LEG GAIT: NOT FIXED, and the earlier note claiming this would fix it was
wrong. The transport was necessary but not sufficient. On a walking run
(new pod_render_joints.conf = the arena mission with BT_JOINTS) all 22 joints
flush as matrices and the renderer applies them, but only handle 0x672 -- the
vehicle ROOT -- animates. The limbs emit their initial pose and never change.
Because nothing drives them. Joint::SetHinge / SetRotation exist, and the
ONLY caller anywhere in the reconstruction is TorsoSimulation
(BT/TORSO.CPP:382, horizontalJointNode->SetRotation). That is why the
torso is the one thing that moves. MAD.SKL declares JointCount=25 --
jointhip, jointlthigh, jointrthigh, jointtorso, jointshakey, jointeye and
the rest -- and the gait that should walk them is simply not reconstructed
yet. Separate piece of work, now unblocked rather than done.
HARNESS CAVEAT: pose_probe frames on "the last-articulated root" in
anim_abs. With 21 joint DCSs now landing there, that heuristic picks a joint
instead of the vehicle root and frames empty arena. The change invalidated
the assumption; the render is not evidence either way until it takes the root
handle explicitly. The counts above are the evidence.
FAULTS SEEN: two crashes during this work, both cr2=7000FA64 at host 66D9 --
the known parked load-window fault, address unmoved across a relink (which is
the standing test for "not ours"). They died at DIFFERENT points ([mer] 217
and [mer] 116), where a defect in new construction code would die
consistently. Third and fourth runs clean.

BT410 5.3.80: joint articulation is live -- 22 nodes, and the twist reaches the board
RecurseSKLFile now builds a joint renderable for any node whose page name resolves to a live skeleton Joint: HingeX/Y/Z -> HingeRenderable (watching Joint::GetHinge), Ball -> BallJointRenderable (watching GetEulerAngles), otherwise the static path. Each holds the rest offset in one DCS and the live rotation in a child DCS, and its Execute diffs the watched value and calls DPL_FLUSH_DCS -- the engine's own mechanism (L4VIDRND.CPP:1026+). The value comes from the mech's JointSubsystem via ResolveJoint, so sim and renderer read one source. Gated on BT_JOINTS while it proves out. [skl] video\max.skl -> 26 nodes, 1 objects, 1 eye, 22 articulated The bridge reported anim_abs=1 joints=0 twist=+0.00 before; it now reports joints=1 twist=-0.86, matching the game's [torso] twist=-0.856. With the mech stationary, frames that differed by 0.0% now differ by 62-80%. A crash it exposed: Mech::ResolveJoint passed segment->GetJointIndex() straight to GetJoint unchecked, and a segment with no joint reports -1 -- GetNthImplementation then indexes [base + -1*4] and dies (guest 00426A1D). Torso never hit it because it only asks for its own authored joint name; the walk asks for every page. Now bounds-checked against GetJointCount. Open: the canopy does not stay rigid in the view, though it and the eye hang off the same articulated node. Cancelling the bridge's cage compensation (CAGE_TWIST_SIGN=0) did not close it. Leading hypothesis: SetupCull builds worldToEyeMatrix from GetSegmentToWorld(siteeyepoint) -- the SIMULATION's segment transform -- independent of the render tree, so the canopy follows our render chain and the eye follows the sim's, and they diverge whenever one carries the twist and the other does not.

BT410 5.3.72: the fault caught in the act; the inside view gets its cockpit
VPX_PF_WATCH (fork, cpu/paging.cpp): on a guest page fault at the watched linear address, dump guest registers, the last 64 serial RX deliveries with guest cs:eip at each, the code bytes at the faulting EIP and the stack top. serialnamedpipe's doReceive feeds the ring. Armed in podrun.sh and launch_pod.ps1. The first catch decoded the residual fault completely: CS:EIP 00FF:000066D4 in the DPMI host, EBX = F000CA60 -- an IVT entry read as a dword, segment F000 offset CA60, a BIOS default interrupt handler -- and the faulting access is [EBX+0x3004], whose 0x80000000 segment-base wrap gives exactly cr2 7000FA64. The host probes a word 0x3004 bytes past a real-mode vector value treated as a flat pointer: harmless for its own low-memory handlers, a fault for BIOS F000:xxxx defaults. The serial ring shows a steady 1-byte/1-3ms vRIO stream with nothing special at the fault -- the stream determines which vectors get walked, not the crash itself. The 0x3004 appears nowhere in DPMI32VM.OVL or 32RTM.EXE as an immediate, so the probe now also dumps code bytes at EIP; faulthunt.sh loops runs until the next catch. Shipped baseline streak: 4/4 clean -- consistent with exposure, not yet discriminating. The inside view now loads the COCKPIT skeleton: the fleet-wide X-variant naming convention (MAD->MAX etc., all 64 skeletons present) selects the same 25-joint chain with a single object -- max_cop.bgf, the MAX_COP canopy shell with the PUNCH-texel windows from the capture forensics. The donor names the same mechanism from the decomp side (inside = SkeletonType_A with '_cop' selection). Fallback to the body skeleton when no X file exists.

BT410 5.3.69: the cockpit eye sits in the canopy -- site handling in the walk
RecurseSKLFile now walks "site=" children. Sites get no draw component -- which is why the walk's 26 nodes matched the real capture all along: sites were never DCS nodes -- and siteeyepoint spawns the cockpit camera with the donor's exact construction (bt411 btl4vid.cpp:462, decomp FUN_004579a8): offset = the site's own local rest transform, parent = the site's PARENT joint's DCS, not the hull root. World orientation, torso twist and gait all arrive through chain composition. The root-DCS eye remains only as the zero-construction fallback for skeletons with no siteeyepoint. Measured on the live pod with the RIO streaming: [eye] cockpit eye on 'jointeye', 26 nodes / 19 objects / 1 eye, and the bridge camera sits at Y = hull + 7.7 -- the exact chain sum jointlocal 5.29 + hip 0.37 + torso 0.31 + jointeye 1.69. canopy_eye1.png is the pilot's view, the mech's own nose wedge visible below the sightline. Own-mech cage handling is the next layer. Also: eye_count threading through ReadSKLFile/RecurseSKLFile, and the [skl] summary now reports it. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> |

BT410 5.3.65: THE MECH STANDS -- wire matrix convention proven from engine source
pose_chase.png: the MadCat assembled from its 19 parts, standing in the arena at its live articulated position. Feet, legs, torso, weapon pods, canopy plate. Not a collapsed stack at the origin, which is what every prior frame actually showed. The convention is no longer inferred -- it is read from the engine. RootRenderable's ctor writes an entity pose into a DCS with *(Matrix4x4*)dpl_GetDCSMatrix(myDCS) = localToWorld, so Matrix4x4::operator=(const AffineMatrix&) IS the wire layout: row-major, rotation in rows 0-2, zeros in column 3, translation in ROW 3 (entries 12/13/14). The old 3/7/11 choice rested on two errors, both corrected in the code comments: AffineMatrix does keep translation at 3/7/11, but because it is COLUMN-major -- citing it as precedent for a row-major layout read the storage and ignored the indexer (AFFNMTRX.HPP:99). And 'the last row made the maths blow up' came from the contaminated bisect; those crashes were the RIO fault. Rotation now composes through the engine's own Matrix4x4::operator=(const EulerAngles&) from the page's pitch/yaw/roll, and the node write uses the RootRenderable idiom (dpl_GetDCSMatrix + assign). Also banked: the chase-frame fifobridge variant -- camera framed on the articulated root instead of the arena bounds -- as the offline proof harness for any future pose question.

BT410 5.3.64: THE COCKPIT EYE IS LIVE -- root+eye composition, and the emulator
deadlock it exposed The camera gap root-caused and fixed through three layers: LAYER 1 (ours): "chain the engine after the skeleton" was a non-fix. The engine's MakeEntityRenderables only accepts Object/Rubble resources, so chaining it with a Skeleton printed "wrong video resource type" and built NOTHING -- the fifodump proved it: zero vr_flush_dcs_artic records. The real fix mirrors the engine's Mover composition (L4VIDEO.CPP:4795-4860) inside our mech case: a Dynamic RootRenderable (whose ctor seeds its DCS from localToWorld and whose Execute re-flushes on change -- the ONLY source of per-frame wire articulation), the skeleton hung UNDER its DCS via ReadSKLFile's new parent_dcs parameter, and for the inside view a DPLEyeRenderable on that root with the published EyepointRotation. Also explains the mystery monolith in the first frame: the skeleton was parked at the world origin with the camera inside its shins. LAYER 2 (1995 library, read from our own linked symbols): dpl_DrawSceneComplete = velocirender_frameack(0), and frameack's unsolicited-reply path prints "dpl error - unsolicited input during frame ack", adds the 1995 authors' own puzzled "flush artic??" when the stray action is 0x1f, and calls exit(9). Documented before it ever fires. LAYER 3 (emulator, the actual deadlock): with per-frame articulation flowing for the first time, the game stopped drawing at frame 232 -- one 0x1f burst per frame forever, no receives, no error. The VPX device feeds the frame ack only after 6 CONSECUTIVE empty polls and reset that counter on EVERY outputData write; per-frame articulation writes made the count unreachable, so dpl_DrawSceneComplete never went true. Fix: the reset is gated on !frame_outstanding -- once a draw is outstanding the only receive the game will do next is the frame ack. The iserver-drain concern the reset guarded is boot-time only, when no frame is outstanding. Verified: two agreeing runs of ours on the fixed emulator (611 draws / 222 artic batches in run 2 -- the 232 wall is gone), camera travelling with the mech (cam -329.7,0,60.5 -> -362.3,0,54.5 across 8s), anim_abs 0 -> 1 on the bridge, view now INSIDE the cockpit cage. Shipped binary re-run on the fixed emulator: launches and runs, no regression. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> |

BT410 5.3.63: the mech gets both skeleton and engine renderables
MakeEntityRenderables no longer stops after the skeleton. It builds ours AND
chains DPLRenderer, which is what creates the RootRenderable and the
DPLEyeRenderable the camera follows. Verified over three runs:
[mer] 208 class=3001 view=1 res=1
[vid] type=1 file='mad.skl'
[skl] video\mad.skl -> 26 nodes, 19 objects
[chain] into DPLRenderer, skeleton=yes, stack at 0x12dde7
No fault, mission launches, sim runs. Worth noting separately: the engine's
eyepoint construction -- prime suspect for the page fault through most of a
session -- runs perfectly here, with the stack at 0x12dde7, right beside the
main loop's frame. Both are consistent with the corrected finding that the
fault is a live-RIO artifact at a fixed DPMI host address.
The camera still does not move: two frames six seconds apart differ by zero
pixels while [sim] shows the mech travelling from (487,20,288) to (493,20,301),
and the bridge reads cam (0.0, 10.0, 0.0) -- world origin plus eye height. So
the eye renderable was necessary but not sufficient.
Eliminated by reading our own code rather than guessing: the viewpoint entity
IS the mech (BTL4APP.CPP:354), the video renderer IS linked to it
(APP.CPP:1337), and SetupCull would Fail() loudly if the mech lacked
"siteeyepoint" or EyepointRotation -- neither Fail appears. That leaves the
path from SetupCull's worldToEyeMatrix to what the bridge reads off the wire,
which is bridge territory rather than reconstruction territory.

BT410 5.3.62: correction -- the fault address was never in our code
Every conclusion that named EulerAngles::operator=(const LinearMatrix&) as the
fault site was wrong, including the disassembly built on top of it. Three
independent proofs:
1. ROTATION.CPP is ours, so the function was instrumented directly -- print
this, &matrix and a local's address on the first twelve calls plus any wild
pointer. The run faulted with ZERO [euler] lines: never called.
2. After the probe was added, 0x66D9 disassembles to a two-byte conditional
jump (jnl) that touches no memory. The dump reports ErrCode 0004, a data
READ.
3. EIP 0x66D9 and cr2 0x7000FA64 are identical to the byte across every build
this session, including builds where the code at that offset changed
completely. A fault in our CODE segment moves when the code moves. This
one does not -- it lives in the DPMI host, which loads low and never gets
relinked.
The map lookup was a coincidence: our _TEXT is section-relative from 0, so its
offsets overlap the host's low addresses, and the map will name a function for
any small number. Before resolving a fault address against the map, confirm it
belongs to our segment -- cheapest check is whether it moves on relink.
What is actually true, by same-binary A/B:
vRIO DOWN, serial1 still a namedpipe -> mission LAUNCHES
vRIO UP, same conf, same binary -> FAULT
The trigger is a LIVE RIO stream, not an unplugged cable. The emulator reports
continuous serial1 RX overruns, the fault lands wherever the app happened to be
(terrain one run, the mech's inside view another), and the shipped binary
survives the identical conditions. A fault at a fixed host address, at
arbitrary points in the app, requiring an interrupt-driven stream, is an
interrupt re-entrancy signature rather than a wild pointer.

BT410 5.3.59: A MISSION RUNS -- the RIO serial port was blocking every load
pod_render_norio.conf is pod_render_rec.conf with one line changed, serial1=disabled instead of the vrio named pipe. Same binary, same egg. With it, our build launches and the mech walks: [launch] state=2 minPriorityEmpty=1 ticks=85316 [queues] p0=- p1=- p2=BUSY p3=- p4=- BTL4Application::RunMissionMessageHandler Turning Plasma Score Display On [sim] pos=(180.466,10,-358.703) yaw=-0.275605 spd=14.4 [sim] pos=(251.959,10,-250.498) yaw=-0.89103 spd=14.4 No fault, 290 log lines and counting. This is the first time the reconstruction has reached a running mission on the pod. The hang was never starvation, a deadlock, or a refill loop -- it was VOLUME, the first candidate I listed and then talked myself out of. 530 renderer events queue at priority 0 during load; BackgroundTasks::Execute runs exactly one task per call round-robin over seven tasks, and the 1ms frame budget is always blown here so no extra background passes happen. That is ~9 events per real second, so a load legitimately takes ~60s. The fault arrived at ~40s, before the backlog could clear. Every 'the queue never drains' reading was really 'the process dies before it can'. The disproof was already in hand: the post tally climbed to 530 and went FLAT, which means nothing was refilling. p0=BUSY with nextReady=1 is equally consistent with a large finite backlog still draining, and I read it as refill. Why the RIO port: the pipe has no server attached, which should behave as an unplugged cable. The emulator log shows steady serial1 RX overruns, our build prints 'RIO never came back from test mode!', and the SHIPPED binary prints 'lost RIO analog request' and launches anyway on this identical rig. So an unplugged RIO is survivable and our handling of it is not -- a real defect, not a rig artifact, since a pod with an unplugged RIO cable should still boot. The wild reference at EulerAngles::operator=(const LinearMatrix&)+0x19 is still unexplained, but it is now reproducible on demand by enabling serial1 rather than being a coin flip.

BT410 5.3.56: the intermittent pod crash is the skeleton walk's -- attributed by same-binary A/B
Added BT_NO_SKL, which skips the skeleton build so ONE executable can be run with and without it. That is the only clean way to test an intermittent fault, and it settles attribution: walk enabled ~50% of runs die (page fault at 66D9) at DIFFERENT points walk disabled 0 crashes in 2 runs shipped exe 0 crashes in 2 runs, same rig and conf So it is our new code, not the rig, and the varying fault point points at memory corruption surfacing later rather than a bad instruction in the walk. Hypotheses killed by reading the private library headers: the matrix array is the right size (dpl_MATRIX is float32[4][4]); and neither s_dplobject nor the common dpl_node header retains an object name, weakening the dangling-string theory (a private name cache inside the library is still possible and is the best surviving suspect). Also checked something that would have been much worse than a crash: ~NotationFile REWRITES its file when dirty, and these are the game's shipped .SKL data files. MAD.SKL is untouched, and ReadSKLFile now carries the engine's own Verify(!IsDirty()) guard. Next tests are listed cheapest-first in the roadmap: keep the NotationFile alive, copy the Object= names, count board allocations, and re-check whether MakeEntityRenderables runs twice per mech.

BT410 5.3.55: the mech skeleton is built -- .SKL walked into a dpl_DCS tree
BTL4VideoRenderer answers MechClassID: walks the video-object chain the way the engine does, hands every L4VideoObject::Skeleton entry to ReadSKLFile, and recurses the .SKL into a dpl_DCS tree with geometry instanced onto it. Verified repeatedly on the live pod: '[skl] video\mad.skl -> 26 nodes, 19 objects', with no 'wrong video resource type' complaint and no load failures. Those counts are exactly what the file declares (25 joint= entries + root, 19 Object= entries). Corrects the earlier success criterion in this file, which said 22 instances by reading the reference capture's 'instance x22' against DZoneCount=22. Damage zones are not geometry -- 28 dzone= tags spread across 19 objects. Translations are written to matrix[3]/[7]/[11], MUNGA's own AffineMatrix layout. It walks cleanly but no frame has been seen WITH the mech yet, so the slot choice is recorded as unconfirmed. Rotation stays identity by design: every base-pose angle in MAD.SKL is 0 or ~1e-3, so translation alone assembles the model and isolates one convention at a time. AND A CORRECTION I have to flag loudly: I earlier concluded from single runs that non-identity translations crashed the pod, 'isolated' it, and 'confirmed' the alternative also crashed. That was all noise. The same binary re-run gives walk / crash / walk / crash -- the known intermittent plane-write defect is now firing on ~half of pod runs and lands at different points each time, which is precisely what made it look deterministic. Never accept a single pod run as evidence on this rig; require two agreeing runs. That defect is now the top of the list: a run must survive both the skeleton build and the launch to render anything, which at ~50% is a coin flip on a four-minute cycle.

BT410 5.3.50: geometry loads -- the bring-up no-op was suppressing the base
DPLRenderer::LoadMissionImplementation (L4VIDEO.CPP:6007) is not empty: it
calls DPLReadEnvironment (which opens L4DPLCFG/btdpl.ini and sets the dPL
object/material/texmap paths from the objectpath= entries) and then
LoadNameBitmaps. The 'bring-up no-op' installed earlier therefore did not do
nothing -- it REPLACED that, so the loader never learned where the art lives
and every dpl_LoadObject returned NULL.
I justified that no-op by pointing at VideoRenderer's bare Tell and
GaugeRenderer's identical one; neither is our base. Check the ACTUAL base
before overriding in this engine and chain it unless there is a reason not
to. DPLReadEnvironment is private to DPLRenderer, so chaining is the only
way a game renderer can reach it at all.
before: 40x 'couldn't load object', 'NULL instance', run ends,
wire ~24 bytes/sec
after: 0 failures, run continues, wire ~12 KB/s (1.17MB climbing),
bridge live at 88fps
Proved it was ours and not the rig by running the SHIPPED exe under the same
conf: it loaded every object. That A/B is cheap and is the right first move
whenever the pod misbehaves.
Still black: the bridge camera sits at its default (0,10,0), so the wire
carries state and object loads rather than a populated scene. The mech and
arena entities still need MakeEntityRenderables bodies.
Rig improvements, both from the user: nosound is fine on the SLOW clock (it
is the FAST SOS clock that needs the AWE32), which saves ~4 min and ~300MB of
audio taps per run; and serial3=file + '> COM3' gives a live unbuffered log,
so a run that does NOT crash is finally readable.

BT410 5.3.49: first renderable answer -- BTPlayer, and the pod stops complaining
BTL4VideoRenderer now overrides MakeEntityRenderables. Class 3035 resolves to BTPlayerClassID (the BT enum block starts at 3000 in VDATA.HPP), and a player carries no graphics -- exactly what the engine already does for its own PlayerClassID with an empty case. Everything else chains to DPLRenderer, so the override can only add answers. On the pod: the 'couldn't figure out how to MakeEntityRenderables' complaint is gone and the run no longer exits, it keeps running. It still renders nothing -- the wire fifodump grows at ~24 bytes/sec, keep-alive rather than a frame stream -- which is expected, since only the player has been answered and the mech and arena still have no renderables. Banked a practical problem worth fixing before the next session: a pod run that does NOT crash produces no readable log, because the conf redirects the game's stdout and DOS buffers it. Every readable log this session came from a run that crashed and had its buffer flushed by the fault handler. The RC.TXT marker (a separate command) survives that, and the com3/serial3=file trick from the emulator notes would give live unbuffered output -- worth wiring in, otherwise progress is invisible precisely when things are going well.

BT410 5.3.42: the 3-D pipeline runs to the geometry load -- two rungs climbed
RUNG 1: BTL4VideoRenderer::LoadMissionImplementation, Fail -> bring-up no-op. Legal, not a cheat: the engine's own VideoRenderer version (VIDREND.CPP:259) is a bare Tell and our working GaugeRenderer ships the same, so the renderer comes up and runs its frame loop with an empty scene -- exactly what we want to measure before writing content. The authentic shape for the real body is pinned by the surviving sibling header CODE/RP/RP_L4/RPL4VID.HPP (walk the mission entities -> MakeEntityRenderables -> ReadSKLFile/RecurseSKLFile). RUNG 2: Mech::EyepointRotation published. The engine then Failed at SetupCull, which fetches that attribute BY NAME off the viewpoint entity and composes it with the siteeyepoint segment to build worldToEyeMatrix. The mech already HAD EulerAngles eyepointRotation with a getter -- only the publication was missing. One enum id, one table row. The run now reaches the full mech build, constructs the renderer, boots the board (~907K VPX wire transactions), loads the mission, runs the per-frame cull and enters geometry loading with ZERO Fails and zero exceptions. It stops at 'couldn't load object buttee.bgf' / 'NULL instance' -- and that is not a defect: the models are present and BTDPL.INI points at them, but .BGF loading goes through the board to the external GL render bridge that the VPX HLE tees over VPX_FIFOSOCK, and that bridge was not running. 'NULL instance' comes from the prebuilt LIBDPL.LIB refusing to instance an object that never loaded. Next rung is the documented full rig (render-bridge/launch_pod.ps1).

4.10 reconstruction: BTL4OPT.EXE links clean and BOOTS to the first staged brick
The reconstructed tree now produces a runnable binary with the authentic 1995 toolchain (BC4.52 / tlink32 / DPMI32): - BTL4.CPP main TU reconstructed from the 4.11 Ghidra decomp (FUN_0040109c) + the 4.10 binary's own string pool + surviving RPL4TOOL.CPP house style; probe_main.cpp scaffold retired (BTL4.NOTES.md documents every decoded call) - L4NET.CPP staged: L4NetworkManager ctor/dtor + 10 vtable-pulled virtuals (standalone-benign ones no-op, network ones Fail loudly) + NetNub client globals (Net_Common_Ptr=NULL routes L4File to its plain-DOS path) - build410.sh: libs now built in the AUTHENTIC makefile member order (MUNGA.MAK / mungal4.mak / BT.MAK / BTL4.MAK). Order is load-bearing: tlink emits static-init records in module pull order, and alphabetical order booted into a null-vptr crash (IcomManager::ClassDerivations constructing before parent NetworkClient::ClassDerivations). Also fixed stage_link to the proven 32-bit lib set (SOSDBXC+SOSMBXC, no WATTCPLG) - BOXTREE.HPP MemoryBlock unify, BTL4GRND notify stubs, remaining engine backfills (audio/gauge/resource/stream TUs) that closed the deep ledger Smoke test (DOSBox-X + 32RTM, copy of the pod BT tree, our exe swapped in): BattleTech v4.10 BTL4Application::BTL4Application l4net.cpp(22): L4NetworkManager -- l4net.cpp not yet reconstructed Static init, main, -egg parse, BTL4.RES load (version 1.0.6 check passes), ApplicationManager and the BTL4Application ctor chain all execute real reconstructed code; boot halts at the first staged Fail() as designed. Next brick: the real l4net.cpp body. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> |
