## Prior compact summary (covers everything before 2026-07-31 23:50)
|
||
|
||
This session is being continued from a previous conversation that ran out of context. The summary below covers the earlier portion of the conversation.
|
||
|
||
Summary:
|
||
1. **Primary Request and Intent:**
|
||
|
||
The user is porting VWE's 1995 arcade **BattleTech** pod game (`BTL4OPT.EXE`, MUNGA engine, Tesla 4.10) to modern Windows, reconstructing game logic from the decompiled binary under strict "no stand-ins, read the decomp" rules (CLAUDE.md router → `context/*.md` KB). This session covered a full night-7 playtest triage-and-fix cycle:
|
||
|
||
1. **Copy the players' downloaded logs** (explicitly: "dont go through them yet").
|
||
2. **Bug-report housekeeping** from the pasted Discord chat: "register new bugs, close out some, add notes to some."
|
||
3. **Opinion (no code)** on whether the ghost mech (#81) and flaming wreck (#94) are separate problems.
|
||
4. **Determine whether Oracle's crash matched Rajel's.**
|
||
5. **Dig into #94**, then implement the fix after a laptop shutdown break ("ok we're back. you can proceed").
|
||
6. **Collision pricing audit**, then "fix it properly and verify it."
|
||
7. **Choose between coolant leaks / myomer heat**, then fix both.
|
||
8. **Question the coolant panel level bar not moving.**
|
||
9. **Explain seek level**, then challenge the conclusion ("seems fishy"), check the manual, and finally issue a definitive correction from player testimony: "ok its definitive, you are wrong about how seek level works. re audit your work and figure out what you got wrong."
|
||
10. **Verify seek-4 overheat specifically.**
|
||
11. **Document research state.**
|
||
12. **Fix Rajel's crash (#93).**
|
||
13. **Fix missile speed (#84).**
|
||
14. **Investigate damage panel darkening (#87)** — user corrected scope to the *mech model*, then shelved it.
|
||
15. **Fix #86** — "weapons on the damaged arms continue to fire even though their mfd entries are X'd out. lets fix that."
|
||
|
||
2. **Key Technical Concepts:**
|
||
- **Gitea tracker** at `https://gitea.mysticmachines.com/api/v1/repos/VWE/BT411`; helper `scratchpad/night7/gitea.py` (`call`, `all_issues`, `create`, `comment`, `close`); labels applied via `PUT /issues/N/labels` with `{'labels':[8]}` (= `awaiting-verification`).
|
||
- **Export-gap blindness (new gotcha #21)**: the Ghidra decomp export has GAPS (issue #60) — e.g. the master-perf region `0x4a9770-0x4ab188`. Text sweeps of `reference/decomp/all/*.c` cannot see un-exported consumers. **Fix: sweep the RAW IMAGE with capstone for the operand addressing pattern.**
|
||
- **The SPLIT CELL (new gotcha #22)**: a binary offset landing *inside* an embedded object in our layout, mirrored as a sibling scalar — writers write one, readers read the other. `subsystem+0x40` IS `statusAlarm@0x2C` + level `+0x14`.
|
||
- **`MechDeathHandler::Tick`** peer un-wreck; `MovementMode` death modes {2,9}; `simulationState` rides every record header.
|
||
- **Collision divert** (`Mech::DistributeCollisionDamage @0049ffcc`): type-0 damage → internal rattle, never armor; scale `(2000/mass)/(100·1/3.6)²/(1−e²)`; 0.5-pt free-tap floor; targets HeatSinkBank 0.3 / Gyro 0.35 / Torso 0.25 / Myomers 0.35.
|
||
- **`Mover::StaticBounce`** returns `-0.0005 * (vn * vp) * moverMass`; crash gate constant at `0x4ab178` = **0.0**; crash-anim threshold `0x4ab184` = 40.0.
|
||
- **Myomer drive heat** `@004b8d18`: `heat += ratio²·(1+dmg)·[0.005·½mv² + 0.2·mg|vy|·dt + 0.2·m|v||a|·dt]`.
|
||
- **Myomer seek→speed** `@0x4a9cf2-0x4a9da4` (un-exported): MAX `speedEffect@0x31C` over myomer chain `+0x7AC` → `mech+0x79C` → `mapper->speedDemand@0x128 *= it`; `turnDemand@0x12C = 0` when `|drive| <= 1e-4` (`_DAT_004ab16c`).
|
||
- **`RegisterMaxOutput @004b8ef0`**: `mech+0x7A0 = max(cap, AvailableOutput(topGear))` = base × ~1.4284.
|
||
- **Authored myomer tuning** (BTL4.RES, one shared record): VelocityEfficiency 0.995, AccelerationEfficiency 0.8, gears 0.3/0.5/0.7/0.9999, recommended idx 2; thermal 77/1000/2000, thermalMass 2.5e5.
|
||
- **Coolant leak chain**: `HeatSink::UpdateCoolant @004adbf8` → `coolantDraw = ownZone->damageLevel × heatLoad`, floor 0.0025, `coolantActive` hysteresis ON >0.003 = the `ReportLeak` attribute; `HeatSink::DrawCoolant` base `@0x4add00` **recurses up** the sink linkage scaled by `coolantFlowScale@0x15C`, terminating at `Reservoir::DrawCoolant @0x4af3b0`.
|
||
- **MissileThruster**: authored in BTL4.RES type-15 (0x54) model records at `+0x44` burn / `+0x48` accel, reached from AmmoBin's `ammoModelFile` through the **type-1 MODELLIST indirection**. SRM 2.5s@600, LRM 10s@300, Streak 3s@300, NARC 10s@300; splash 30.
|
||
- **Bench env gates added this session**: `BT_SELF_DAMAGE_TYPE=collision`, `BT_SELF_DAMAGE_ZONE=dz_*`, `BT_FORCE_SEEK=<idx>`, `BT_KILL_SUBSYS=<name>`, plus existing `BT_SHOT_EVERY`/`BT_SHOT_PREFIX`, `BT_GOTO_STOP`, `BT_AF_MISSILE`, `BT_AF_PERIOD`, `BT_SPAWN_ENEMY`, `BT_DRIVE_LOG`, `BT_COOL_LOG`, `BT_CRIT_LOG`, `BT_MYO_LOG`.
|
||
- **Clock offsets for log correlation**: Oracle/Sauron = Discord **+1:00**, Rajel = Discord **−2:00** (Rajel exactly 3:00:00 behind the others).
|
||
|
||
3. **Files and Code Sections:**
|
||
|
||
- **`scratchpad/night7/gitea.py`** (NEW) — shared tracker helper used for all issue work.
|
||
- **`game/reconstructed/mechdmg.hpp`** — replaced `Logical wasWrecked` with `int prevMode` for the #94 fix.
|
||
- **`game/reconstructed/mechdmg.cpp`** — #94 death-state EXIT edge watcher at top of `MechDeathHandler::Tick`:
|
||
```cpp
|
||
const int mode = (int)owner->MovementMode();
|
||
const int oldMode = prevMode;
|
||
const bool nowDead = (mode == 2 || mode == 9);
|
||
const bool prevDead = (oldMode == 2 || oldMode == 9);
|
||
prevMode = mode;
|
||
if (prevDead && !nowDead && owner->GetInstance() == Entity::ReplicantInstance)
|
||
{ BTRebuildMechModel(...); BTStartWarpEffect(...); }
|
||
```
|
||
Also added crit-subsystem NAME to the cascade log: `<< " '" << (s->GetName() ? s->GetName() : "?") << "'"`.
|
||
- **`game/reconstructed/mech4.cpp`** — many edits: `BTMechMyomerMotionSample` bridge (localVelocity/localAcceleration/moverMass/gravity); `BTMechRunSpeedBase`/`BTMechTopSpeedGet`/`BTMechTopSpeedSet`; removed `gBlockCooldown`/`kBlockHysteresis`/`freshBlock`; raw ram dispatch (`dmg.damageAmount = resolved->damageAmount;`); `BTProjectilesDropEntity`/`BTProjectilesClearAll`; `BTMissileThrustOf` (RES parse + ModelList aliasing); thruster burn integration; `BT_SELF_DAMAGE_TYPE=collision`; `dz_*` named-zone mode using `Entity::GetDamageZoneIndex(CString(ze))`; **`BT_KILL_SUBSYS` hook**:
|
||
```cpp
|
||
if ((Entity *)this == application->GetViewpointEntity() && getenv("BT_KILL_SUBSYS"))
|
||
{
|
||
static int s_ksFrame = 0;
|
||
if (++s_ksFrame == 900) {
|
||
const char *want = getenv("BT_KILL_SUBSYS");
|
||
for (int i = 2; i < GetSubsystemCount(); ++i) {
|
||
Subsystem *s = GetSubsystem(i);
|
||
if (s == 0 || s->GetName() == 0) continue;
|
||
if (stricmp(s->GetName(), want) != 0) continue;
|
||
if (!s->IsDerivedFrom(MechSubsystem::ClassDerivations)) continue;
|
||
((MechSubsystem *)s)->SetSubsystemDamageLevel(1.0f);
|
||
((MechSubsystem *)s)->ForceCriticalFailure();
|
||
DEBUG_STREAM << "[killsub] '" << s->GetName() << "' force-destroyed ..." ;
|
||
break;
|
||
}
|
||
}
|
||
}
|
||
```
|
||
- **`game/reconstructed/projweap.cpp`** — **the #86 fix**:
|
||
```cpp
|
||
int gate1Destroyed = (simulationState == 1
|
||
|| statusAlarm.GetLevel() == 1);
|
||
```
|
||
- **`game/reconstructed/emitter.cpp`** — **the #86 fix, energy side**:
|
||
```cpp
|
||
if (simulationState == 1 || statusAlarm.GetLevel() == 1
|
||
|| GetFaultState() == 2 || BTMechDestroyed((Entity *)owner))
|
||
```
|
||
- **`game/reconstructed/mechmppr.cpp`** — the myomer drive scale REMOVED (cf8618b) then RESTORED byte-grounded (905a4a8): MAX over the myomer chain via `BTMyomersSpeedEffectOf`, `speedDemand *= drive`, and `if (fabsf(drive) <= 1.0e-4f) turnDemand = 0.0f;`.
|
||
- **`game/reconstructed/myomers.cpp/.hpp`** — real motion operands; `RegisterMaxOutput()` called per tick; ConnectToMover family deleted; `BTMyomersSpeedEffectOf` (unclamped) replaced `BTMyomersDriveOf`; `BT_FORCE_SEEK` bench hook.
|
||
- **`game/reconstructed/mechsub.cpp`** — the #88/#64 alias in **both** ctors: `Subsystem::damageZone = (::DamageZone *)damageZone;`
|
||
- **`game/reconstructed/heat.cpp`** — `HeatSink::DrawCoolant` recursion:
|
||
```cpp
|
||
HeatSink *linked = (HeatSink *)linkedSinks.Resolve();
|
||
requested *= coolantFlowScale;
|
||
if (linked == 0) return 0.0f;
|
||
return linked->DrawCoolant(requested);
|
||
```
|
||
- **`game/reconstructed/mech.cpp`**, **`game/btl4main.cpp`**, **`engine/MUNGA/CULTURAL.cpp`** — #93 projectile-pool scrub call sites.
|
||
- **`game/reconstructed/mislanch.cpp` / `projweap.cpp`** — `BTPushProjectile` extended with `thrust_accel`/`thrust_burn` (defaults 0/0).
|
||
- **KB files updated**: `context/multiplayer.md`, `context/translocation-warp.md`, `context/combat-damage.md`, `context/locomotion.md`, `context/rendering.md`, `context/subsystems.md`, `context/pod-hardware.md`, `context/open-questions.md`, `context/reconstruction-gotchas.md` (§21 export-gap blindness, §22 split cell), `docs/SUBSYS_PLAN.md`, `phases/phase-13-night7-collision-myomer-coolant.md` (NEW).
|
||
- **Bench scripts (NEW)**: `scratchpad/night7/mp_zoneless.sh`, `mp_rampricing.sh`, `mp_teardown.sh`.
|
||
|
||
4. **Errors and fixes:**
|
||
- **My own bug in the #94 edit**: overwrote `prevMode` before the log printed it → added `oldMode` snapshot.
|
||
- **Edit tool "String to replace not found"** repeatedly on tab-indented files → used python with exact `\t` strings.
|
||
- **C2001 "newline in constant"** — a literal newline inside a `DEBUG_STREAM` string in `BTMissileThrustOf` → replaced with `\n`.
|
||
- **C2660 `GetDamageZoneIndex` wrong overload** — `JointedMover`'s static takes 2 args → qualified as `Entity::GetDamageZoneIndex(CString(ze))`.
|
||
- **Ram bench produced 0 dispatches** — `BT_GOTO=enemy` stops at 300 units → added `BT_GOTO_STOP=2`.
|
||
- **Thrust resolution `hit=0`** — AmmoBin's `ammoModelFile` points at the type-1 MODELLIST, not the type-15 model → added pass-2 list aliasing.
|
||
- **Bench couldn't find the zone carrying a weapon** (`dz_rarm` hit Condenser6, `dz_rmissle` doesn't exist on Black Hawk) → replaced zone-guessing with the `BT_KILL_SUBSYS` direct-destruction hook.
|
||
- **`LNK1104 btl4.exe` / "Device or resource busy"** — stale running process → `taskkill //F //IM btl4.exe` + short sleep before rebuild/rm.
|
||
- **MAJOR — user-corrected wrong verdict**: I declared "the binary has NO dynamic myomer→speed coupling" (commit cf8618b) and filed the manual's Supercharge as a 4.0→4.10 drift. The user pushed back twice ("seems fishy"; then "ok its definitive, you are wrong"). Root cause of MY error: **export-gap blindness** — I swept decompiled *text* for callers, but the consumer lives in an un-exported region. A raw-image capstone scan for FPU reads of `[reg+0x31C]` found it in one pass. Retracted and restored byte-grounded (905a4a8); filed gotcha #21; corrected #75 and #19 on the tracker.
|
||
- **User scope correction on #87**: "i dont think he meant the doll cutout. i think the panels on the actual mech are supposed to show damage" → I checked authored skeleton data instead of gauge code.
|
||
|
||
5. **Problem Solving:**
|
||
Fourteen commits, all bench-verified and pushed. Solved: #94 zone-less-death un-wreck (14/14 collision, 12/12 explosive); collision economy (grind death removed — 125 paced binds/0 deaths; raw ram restored — victim priced 2.55 pts); #85 myomer drive heat (T 77→1225 with coolant recovery); #88 coolant leaks both halves (arming via the #64 engine-member alias; central tank drained 6.0→5.58); #93 end-of-round crash (disasm-pinned to `BTUpdateProjectiles`' non-mech branch — the `BTIsRegisteredMech` guard *routed* the dangling pointer into the unguarded branch; 6/6 clean teardowns); #84 missile thrust (impacts at v=277 vs constant 100); seek→speed retraction + full verification (drive 1.42843, 193 kph, T 531→1765, throttle to 0.62, settle ~0.77); #86 destroyed weapons (A/B: destroyed launcher 0 salvos, control 2, gate `destroyed=1`).
|
||
Open/parked: #87 (mech-model panel darkening — user is confirming with players whether they mean the 3D model; authored data shows damaged variants exist ONLY for arms/guns, and the cockpit schematic tint is verified working); the seek "who saw what in which pod version" question is now resolved in favor of the manual; carried opens (cross-fire stall, silent node crash, 17s-late kill credit, environment gravity unwired, #64 full de-shadow sweep, mech3 stub bridges).
|
||
|
||
6. **All user messages:**
|
||
- "ok players are done for the night. i downloaded their logs. can you copy them here? dont go through them yet. ill post the chat text next"
|
||
- "i guess they just sent these. here is the chat text. we had a new player tonight that knew quite a lot about the original game play. some of our fixes hit. some mostly hit. lets start with some bug report house keeping. register new bugs, close out some, add notes to some:" [followed by the full Discord transcript]
|
||
- "so our ghost mech and our flaming wreck seem like separate problems then? or have we not fully solved the ghost mech issue? dont fix any code yet. just give me your opinion"
|
||
- "ok but before that oracle also had a crash on exit that he mentioned. was it the same as rajel's?"
|
||
- "ok what was bug 94? just a one line description is fine"
|
||
- "ok lets dig in"
|
||
- "i have to shut down the laptop but we can implement this once we come back online"
|
||
- "ok we're back. you can proceed"
|
||
- "ok lets do the collision pricing audit"
|
||
- "fix it properly and verify it"
|
||
- "ok so apparently our coolant is leaking when the mechs get damaged and myomers are apparently not heating up. which of those should we look into"
|
||
- "i meant isnt leaking"
|
||
- "sounds good. go for it"
|
||
- "so in the coolant panel there is some sort of level bar.. i didnt see that going down during your tests.. i might have been misinterpretting it"
|
||
- "ok for the myomers.. did you look into the seek levels? oracle apparently said he set to seek level 4 and it didnt do anything. i guess thats a speed setting or something?"
|
||
- "ok in one sentence, what does the seek level do?"
|
||
- "how does that make any sense that it woulnt change your speed. are you 100% sure of that? otherwise you can just set a low gear to load the generator and it costs you nothing as far as perforamnce. seems fishy"
|
||
- "do we have the manual archived? does it go over this?"
|
||
- "ok we'll come back to this. im checking with players. lets document where we are at with our research"
|
||
- "ok how about rajel's crash?"
|
||
- "ok so next people have been complaining about missle speed. can you check the binary and see where we are going wrong on that one"
|
||
- "ok its definitive, you are wrong about how seek level works. re audit your work and figure out what you got wrong:" [followed by Discord quotes: epilectrik "is seek level supposed to effect top speed"; Oracle "Yes / A seek 4 humanoid leg neck will move at 182 kph / Game changer. Also turns faster / I recall heavy chicken walkers going 229 or so and Owens Blackhawk around 300. / Myomers generated a lot of heat especially at seek 4. Most mechs could only run at top speed in seek 4 for less than a minute without overheating and freezing up. / Very big effect on gameplay"; RajelAran "the myomer seek functionality is also referenced in the manual"]
|
||
- "ok so is the code fixed? did you verify that seek level 4 overheats myomers now"
|
||
- "ok what about the darkening mech panels on damage? have we ever looked into that?"
|
||
- "i dont think he meant the doll cutout. i think the panels on the actual mech are supposed to show damage"
|
||
- "im pretty sure they mean the mech, not the doll. but im confirming. lets shelve this for now and move on to weapons on the damaged arms continue to fire even though their mfd entries are X'd out. lets fix that"
|
||
- "please proceed"
|
||
- **Security constraints carried forward from earlier context (verbatim, still in force):** credentials epilectrik/eLUavSwBM8a8RAC for mysticmachines.com/gitea (stored in Windows Credential Manager; rotation recommended); `operator_secret.txt` NEVER commit; do not forward port 1507 to the open internet; `scratchpad/night5/` and `night6/` logs NOT committed (player IPs, Steam IDs, machine names) — bench .sh scripts within night6 are committed but field logs/AGENT_FINDINGS.md are not; OS screen-capture of the user's desktop is off-limits (in-engine BT_SHOT_EVERY/BT_SHOT_PREFIX backbuffer capture only).
|
||
|
||
7. **Pending Tasks:**
|
||
- **#87 (mech-model panel darkening)** — explicitly shelved by the user pending player confirmation of whether they mean the 3D model or the cockpit schematic. Findings already posted to #87 and #80.
|
||
- Cut a dist zip for the next playtest (offered, never requested).
|
||
- Carried opens filed in `context/open-questions.md`: cross-fire combat stall, silent node crash (procdump armed), 17s-late kill credit, environment gravity unwired (myomer climb-heat term inert), the #64 full de-shadow sweep, mech3 `CreateStreamedSubsystem` stub bridges.
|
||
|
||
8. **Current Work:**
|
||
Immediately before the summary request I completed **#86 — "weapons on the damaged arms continue to fire even though their mfd entries are X'd out"**, the user's most recent explicit task.
|
||
- **Root cause (the SPLIT CELL)**: both fire gates test the binary's `subsystem+0x40` for Destroyed(1). In the 1995 layout that offset IS the status alarm's level cell (`statusAlarm@0x2C` + level `+0x14`) — one cell, written by `ForceCriticalFailure`. The port models it as TWO members (`AlarmIndicator statusAlarm` and a plain `int simulationState@0x40`); destruction writes only the alarm (hence the correct MFD X), while the gates read the never-written int. The tell had been in our logs for weeks: `[ammo] SRM6_1 -> NoAmmo (gate1): destroyed=0` on a mech with an X'd-out launcher.
|
||
- **Fix**: both gates now also read `statusAlarm.GetLevel() == 1` (`projweap.cpp` gate 1, `emitter.cpp` hard failure).
|
||
- **Verification (A/B in one run)** using the new `BT_KILL_SUBSYS=SRM6_1` hook: BEFORE kill `{SRM6_1: 2, SRM6_2: 2}` salvos; AFTER kill `{SRM6_2: 2}` only, with `[ammo] SRM6_1 -> NoAmmo (gate1): destroyed=1`.
|
||
- Committed **`5410371`** and pushed; KB gotcha **§22** added to `context/reconstruction-gotchas.md` plus a `context/combat-damage.md` entry; reported on **#86** (labeled `awaiting-verification`) and **#30** (enforcement half done; presentation half remains that issue's scope).
|
||
|
||
9. **Optional Next Step:**
|
||
None without user direction — the user's most recent explicit task ("lets fix that", re: #86) is complete, committed, pushed, verified, and reported. The natural follow-ups, both requiring user confirmation, are: (a) cutting the dist zip for the next playtest, since nine player-facing fixes are now queued awaiting-verification, and (b) resuming **#87**, which the user explicitly shelved: *"im pretty sure they mean the mech, not the doll. but im confirming. lets shelve this for now and move on to weapons on the damaged arms..."*

|
||
Continue the conversation from where it left off without asking the user any further questions. Resume directly — do not acknowledge the summary, do not recap what was happening, do not preface with "I'll continue" or similar. Pick up the last task as if the break never happened.

### [2026-07-31 23:52:28] USER
|
||
|
||
ok so its confirmed that the actual mech armor is supposed to darken and show damage. its not complete in its current state just swapping limbs for broken limbs. i suspect there is a more subtle retexturing that needs to happen or perhaps even a filter or effect that isnt being applied:
|
||
|
||
|
||
|
||
¡Oracle! — 2:01 PM
|
||
|
||
Yes for #5, the actual enemy mech in external view is not showing darkened armor panels.
|
||
|
||
**[2026-07-31 23:52:36] CLAUDE:**
|
||
|
||
Confirmed — so it's the mech model itself, not the doll. Let me ground this in the binary rather than guess at an effect.
|
||
|
||
**[2026-07-31 23:52:52] CLAUDE:**
|
||
|
||
The `.DZM` lead plus a `dpl_Damagize` DPL command — that's the mechanism. Reading both.
|
||
|
||
**[2026-07-31 23:53:02] CLAUDE:**
|
||
|
||
`destroyed`, `destroyeds`…`destroyedd` — that's a *set* of skin variants, not one. Reading the authoring table.
|
||
|
||
**[2026-07-31 23:53:22] CLAUDE:**
|
||
|
||
Eight variants: `destroyed`, `+s`, `+t`, `+o`, `+a`, `+b`, `+c`, `+d`. Reading the parser that consumes them.
|
||
|
||
**[2026-07-31 23:53:56] CLAUDE:**
|
||
|
||
The other half: `dpl_Damagize` — punch's sibling, same board command, different tokens. That's a *geometry-swap* mechanism we already have the machinery for.
|
||
|
||
**[2026-07-31 23:54:16] CLAUDE:**
|
||
|
||
`dpl_Damagize` takes a **second geometry** (`param_2+8`) — tokens `f_t_dam(0x92)/sca(0x05)/undamage(0x04)`. So damage is a bound *variant geometry*, board-swapped. No callers in the export — that's gotcha #21 territory, so I'll sweep the raw image.
|
||
|
||
**[2026-07-31 23:54:55] CLAUDE:**
|
||
|
||
Both callers sit in the same SV_SPECIAL callback we already decoded for punch. Disassembling that region.
|
||
|
||
**[2026-07-31 23:55:26] CLAUDE:**
|
||
|
||
The error string settles it: **"SPECIAL GEOGROUP DAMAGE couldn't find material"** — `dpl_Damagize` binds a damaged **material**, not geometry. That's the retexturing. Let me confirm the lookup and check the corpus.
|
||
|
||
**[2026-07-31 23:55:57] CLAUDE:**
|
||
|
||
Confirmed — `FUN_00497678` is the material lookup (tags 0x2030/0x2031, `DEFAULT` material). Now the decisive question: do the shipped mech BGFs actually carry `DAMAGE` tokens?
|
||
|
||
**[2026-07-31 23:56:23] CLAUDE:**
|
||
|
||
Zero. The engine supports it but **no shipped asset uses it** — that path is a dead end. Back to the `.DZM` lead, which is described as exactly "damage-zone→material map".
|
||
|
||
**[2026-07-31 23:56:38] CLAUDE:**
|
||
|
||
**Found it.** `.DZM` is a per-mech damage-zone → material-list registry. Let me find the parser and, critically, what it *does* with those materials.
|
||
|
||
**[2026-07-31 23:56:58] CLAUDE:**
|
||
|
||
Note `dzms/dzmt/dzmo/dzma/dzmb/dzmc/dzmd` — the same suffix family as the `destroyed*` set (8 skin variants). And mechs are no-normal geometry, so they're colored by **material ramp**. Let me test the ramp hypothesis.
|
||
|
||
**[2026-07-31 23:57:39] CLAUDE:**
|
||
|
||
Now the runtime side. Let me find `dpl_SetMaterialRamp` and see who calls it.
|
||
|
||
**[2026-07-31 23:58:07] CLAUDE:**
|
||
|
||
`dpl_SetMaterialRamp` @ `0x48bfb0` — writes `material+0x1c = ramp`. Now, who calls it?
|
||
|
||
**[2026-07-31 23:58:19] CLAUDE:**
|
||
|
||
Only one caller (load-time BMF binding). So ramps aren't swapped at runtime. Let me find the runtime consumer via the material-lookup-by-name function instead.
|
||
|
||
**[2026-07-31 23:58:31] CLAUDE:**
|
||
|
||
Not exported — another gap. Disassembling it directly.
|
||
|
||
**[2026-07-31 23:58:49] CLAUDE:**
|
||
|
||
The payload creates a 232-byte object bound to the material with `0.1f`. Let me identify the constructor and read the error strings — they'll name the system.
|
||
|
||
**[2026-07-31 23:59:00] CLAUDE:**
|
||
|
||
The same call site **is** exported in part_014. Reading the readable version.
|
||
|
||
**[2026-07-31 23:59:14] CLAUDE:**
|
||
|
||
**`BTL4VideoRenderer: Material name <X> could not be found`** — this is the mech skin damage renderer. Per zone → a node; per material in that zone → a child bound to `(material, zone+0x158, 0.1f)`. Reading that class.
|
||
|
||
**[2026-07-31 23:59:36] CLAUDE:**
|
||
|
||
Mechanism fully decoded. Now let me confirm the watched field and check what our port implements.
|
||
|
||
**[2026-07-31 23:59:58] CLAUDE:**
|
||
|
||
`zone+0x158` = `damageLevel` — confirmed against our own layout lock. Now let me see what `btl4vid.cpp` (our BTL4VideoRenderer) actually does.
|
||
|
||
**[2026-08-01 00:00:22] CLAUDE:**
|
||
|
||
Our renderer does material *substitution* and limb graphic-states — but there is **no** per-zone material darkening. That's the missing piece. Let me identify the material colour accessors to be sure what's being scaled.
|
||
|
||
**[2026-08-01 00:00:57] CLAUDE:**
|
||
|
||
The engine already has `MaterialList` — the DZM data path exists in real MUNGA source (T0). Let me read it.
|
||
|
||
**[2026-08-01 00:01:09] CLAUDE:**
|
||
|
||
T0-confirmed: `DamageZone` already parses the DZM record into a `materialTable` keyed by skeleton type. The data is loaded and sitting unused. Let me pin the hook site and our material API.
|
||
|
||
**[2026-08-01 00:01:33] CLAUDE:**
|
||
|
||
The 2007 port left every `dpl_SetMaterial*` call commented out — so there's no live material-colour channel. Let me check what the draw path actually carries.
|
||
|
||
**[2026-08-01 00:02:32] CLAUDE:**
|
||
|
||
Let me confirm the name-matching key — do the shipped BGF material names line up with the DZM entries?
|
||
|
||
**[2026-08-01 00:03:16] CLAUDE:**
|
||
|
||
Let me verify the lerp constant before I report.
|
||
|
||
**[2026-08-01 00:04:12] CLAUDE:**
|
||
|
||
Research is complete and the mechanism is fully decoded. Your instinct was right — it's a retexture, not a limb swap.
|
||
|
||
## How the 1995 game darkens armor
|
||
|
||
It's a **per-zone, per-material colour ramp-down**, driven live off the damage zone's `damageLevel`:
|
||
|
||
1. **`.DZM` files** (40 shipped, one per mech skin — `AVASKIN.DZM`, `MADSKIN.DZM`, …) map each damage zone to the list of materials painted on it:
|
||
```ini
|
||
[dz_ltorso]
|
||
material=avaskin:avat4_dz_ltorso_mtl
|
||
material=avaskin:avat2_dz_ltorso_mtl
|
||
```
|
||
2. Those lists compile into BTL4.RES and load in **`DamageZone::DamageZone(stream)`** — this is real MUNGA source we already compile [T0], `engine/MUNGA/DAMAGE.cpp:311-336`. The data is **already in memory in our build**, keyed by skeleton type (the eight `dzm`/`dzms`…`dzmd` skin variants).
|
||
3. **`BTL4VideoRenderer::MakeMechRenderables`** (`FUN_004cef28`) walks the zones and, per material, creates a 232-byte watcher — `FUN_004573e4(material, &zone->damageLevel, 0.1f)`.
|
||
4. That watcher snapshots the material's **16 authored colour floats** (Ambient 3, Emissive 3, Diffuse 3, Specular+shininess 4, Opacity 3), precomputes a damaged set = **pristine × 0.1**, and every frame the level changes (`FUN_00457784`) writes back `lerp(pristine, damaged, damageLevel)` — constant pinned at `0x4579a4` = **1.0** — then flushes the material.
|
||
|
||
So a zone at full damage renders its panels at **10% brightness**, continuously interpolated on the way there. [T1 — decompiled, callers recovered by raw-image sweep, constants disasm-verified]
|
||
|
||
One faithful quirk worth keeping: Opacity is read and lerped but **never written back** — only 13 of the 16 values get pushed.
|
||
|
||
## Why ours doesn't do it
|
||
|
||
Two independent gaps, which is why it looks half-finished rather than absent:
|
||
|
||
- Our `BTL4VideoRenderer` implements material *substitution* (team colours) and the segment graphic-state swaps — that's the limb-swapping you're seeing — but has **no material-damage watcher at all**.
|
||
- The 2007 WinTesla port left **every `dpl_SetMaterial*` call commented out** (`L4VIDRND.cpp:5067+`), so there's no live material-colour channel to write to. Batch colour is baked into a `D3DMATERIAL9` once at load.
|
||
|
||
I also chased and **eliminated** a plausible-looking alternative: the engine has a `SV_SPECIAL DAMAGE <material>` path (`dpl_Damagize`, punch's sibling, error string *"SPECIAL GEOGROUP DAMAGE couldn't find material"*). A scan of all 879 shipped BGFs found **zero** DAMAGE tokens — unused in shipped content. Not the mechanism. [T2]
|
||
|
||
Good news for the fix: I verified the BGF material names match the DZM entries **exactly**, with no substitution placeholders on these, so the zone→material match is a direct string key.
|
||
|
||
Implementation needs three pieces: carry the authored material name on the draw batch, build the matName→zone map per mech from the already-loaded `GetMaterialList`, and apply `1 − 0.9·damageLevel` to the draw-op material each frame (equivalent to the binary's lerp, and it composes correctly with the ramped/white-material path).
|
||
|
||
That's a renderer-core change rather than a localized one, so before I start cutting into `bgfload` and the D3D draw path — want me to proceed with it now, or cut the dist zip first so the ten already-verified fixes get in front of players this round?
|
||
|
||
### [2026-08-01 00:06:06] USER
|
||
|
||
lets fix it now
|
||
|
||
**[2026-08-01 00:06:10] CLAUDE:**
|
||
|
||
Let me start with the draw batch carrying its material name.
|
||
|
||
**[2026-08-01 00:06:24] CLAUDE:**
|
||
|
||
Now the batch material name. First the struct field:
|
||
|
||
**[2026-08-01 00:06:50] CLAUDE:**
|
||
|
||
Now the draw side. Let me look at the draw-op structure and where materials are used at draw time.
|
||
|
||
**[2026-08-01 00:07:31] CLAUDE:**
|
||
|
||
`L4DRAWOP` is memset-zeroed, so it must stay POD. Adding a zero-safe pair of fields:
|
||
|
||
**[2026-08-01 00:07:47] CLAUDE:**
|
||
|
||
Now populate the name at load and apply the modulation at draw:
|
||
|
||
**[2026-08-01 00:08:36] CLAUDE:**
|
||
|
||
Now the game side. Let me see how mech segments map to renderables.
|
||
|
||
**[2026-08-01 00:09:34] CLAUDE:**
|
||
|
||
Good hook point. Adding the per-frame tick right after the death handler:
|
||
|
||
**[2026-08-01 00:09:43] CLAUDE:**
|
||
|
||
Now the render-tree binding. Adding the storage:
|
||
|
||
**[2026-08-01 00:10:27] CLAUDE:**
|
||
|
||
Let me bind per draw-op instead of by name each frame — cheaper and simpler.
|
||
|
||
**[2026-08-01 00:10:46] CLAUDE:**
|
||
|
||
Now the implementation in `btl4vid.cpp`:
|
||
|
||
**[2026-08-01 00:11:36] CLAUDE:**
|
||
|
||
Critical: the geometry swap replaces draw objects, which would leave stale pointers. Let me check.
|
||
|
||
**[2026-08-01 00:11:45] CLAUDE:**
|
||
|
||
Important — I need to check whether `LoadObject` caches objects across mechs. If it does, damage would bleed between mechs.
|
||
|
||
**[2026-08-01 00:12:13] CLAUDE:**
|
||
|
||
No caching — each mech gets its own draw objects, so no cross-mech bleed. But the graphic-state swap replaces objects without updating `segPick`, which would strand the bindings:
|
||
|
||
**[2026-08-01 00:12:24] CLAUDE:**
|
||
|
||
Now the respawn heal path:
|
||
|
||
**[2026-08-01 00:12:46] CLAUDE:**
|
||
|
||
Now let me build.
|
||
|
||
**[2026-08-01 00:16:04] CLAUDE:**
|
||
|
||
Build succeeded. Let me add a change-gated diagnostic so I can prove the level actually reaches the draw ops:
|
||
|
||
**[2026-08-01 00:16:39] CLAUDE:**
|
||
|
||
Clean build. Let me look at an existing bench script to match the run pattern.
|
||
|
||
**[2026-08-01 00:18:20] CLAUDE:**
|
||
|
||
Release links (the LNK2019s are the known `/FORCE`-tolerated mech3 stubs). Now the bench:
|
||
|
||
**[2026-08-01 00:20:30] CLAUDE:**
|
||
|
||
Bindings resolve to zero. The lists exist but nothing matches — let me dump both sides.
|
||
|
||
**[2026-08-01 00:22:39] CLAUDE:**
|
||
|
||
The mismatch is the skeleton variant: geometry is `blxskin:` but I'm asking for skeleton 0's list (`blhskin:`). I should key on the skeleton actually **displayed**.
|
||
|
||
**[2026-08-01 00:24:41] CLAUDE:**
|
||
|
||
Bindings resolve now — 57 on the enemy mech (the reported case). Now the levels:
|
||
|
||
**[2026-08-01 00:25:03] CLAUDE:**
|
||
|
||
The player mech is in cockpit view (bench_common's player env sets `BT_START_INSIDE=1`, overriding mine) — so the 57-binding entity is the enemy, exactly the reported case. Let me damage the *enemy* and lower the dose to show the gradient.
|
||
|
||
**[2026-08-01 00:27:21] CLAUDE:**
|
||
|
||
The gradient is exact (`brightness = 1 − 0.9·level`), and only the targeted zone moves. Now the reported case — an enemy hull under fire, with screenshots:
|
||
|
||
**[2026-08-01 00:29:15] CLAUDE:**
|
||
|
||
Shots are `.png`, not `.tga` — my listing was wrong:
|
||
|
||
**[2026-08-01 00:29:28] CLAUDE:**
|
||
|
||
Let me look at the frames — first (enemy undamaged) versus last (after sustained fire):
|
||
|
||
**[2026-08-01 00:29:39] CLAUDE:**
|
||
|
||
The cockpit frame doesn't frame the enemy well. For a clean pixel read I need the external view — which `bench_common` forces to cockpit. Adding an explicit external leg:
|
||
|
||
**[2026-08-01 00:31:33] CLAUDE:**
|
||
|
||
Full ramp 0 → 1 captured. Comparing the first and last external frames:
|
||
|
||
**[2026-08-01 00:31:48] CLAUDE:**
|
||
|
||
Presence-only gate — `=0` still counts as set. Needs `unset`:
|
||
|
||
**[2026-08-01 00:35:24] CLAUDE:**
|
||
|
||
External view now uses the `blhskin` (outside) set — 3 materials on that zone, confirming the view-skeleton rebind works. Let me check the frames:
|
||
|
||
**[2026-08-01 00:35:36] CLAUDE:**
|
||
|
||
The upper torso is visibly darkened while the limbs stay white. Confirming against the undamaged baseline:
|
||
|
||
**[2026-08-01 00:35:44] CLAUDE:**
|
||
|
||
Let me measure this properly rather than eyeball it:
|
||
|
||
**[2026-08-01 00:36:05] CLAUDE:**
|
||
|
||
The frames aren't a clean comparison (smoke drift, and the mech dies partway). Let me add a bench gate that forces a fixed level so I can diff the identical scene:
|
||
|
||
**[2026-08-01 00:39:26] CLAUDE:**
|
||
|
||
Let me confirm whether the force actually applied before blaming the draw path:
|
||
|
||
**[2026-08-01 00:41:45] CLAUDE:**
|
||
|
||
The force applied (57 bindings at 0.1×) but nothing changed on screen — so material colour isn't reaching the mech pixels. Let me look at the actual texture/lighting state:
|
||
|
||
**[2026-08-01 00:42:18] CLAUDE:**
|
||
|
||
Found it: D3D9 defaults `DIFFUSEMATERIALSOURCE` to vertex colour, and our BGF verts carry colour — so the material diffuse is ignored entirely. Let me check whether stage 1 is free for a modulate:
|
||
|
||
**[2026-08-01 00:42:36] CLAUDE:**
|
||
|
||
Stage 1 is free in this draw path. Let me switch from material scaling (ignored) to a texture-factor modulate, which multiplies the final colour regardless of the diffuse source:
|
||
|
||
**[2026-08-01 00:42:48] CLAUDE:**
|
||
|
||
Now replacing the ineffective material scale with a texture-factor modulate:
|
||
|
||
**[2026-08-01 00:45:34] CLAUDE:**
|
||
|
||
The mech renders near-black at forced level 1.0. Let me quantify on the hull only:
|
||
|
||
**[2026-08-01 00:46:19] CLAUDE:**
|
||
|
||
Strong, specific darkening (hull 0.35× including edges/unbound parts; terrain control 0.98×), with the per-op math exact. Let me clean up the triage logging into a real diagnostic:
|
||
|
||
**[2026-08-01 00:47:25] CLAUDE:**
|
||
|
||
Final regression + confirmation run — real damage, no forcing:
|
||
|
||
**[2026-08-01 00:49:28] CLAUDE:**
|
||
|
||
All ten unmatched names are `damcolor_`/`gen*gry_` on arm/gun zones — those live on the **destroyed-limb** meshes (`AVAD*.BGF`), which only load once a limb hits Destroyed. Correct behaviour, and the rebind picks them up on swap.
|
||
|
||
Now the knowledge base. Let me check the gotcha numbering:
|
||
|
||
**[2026-08-01 00:51:44] CLAUDE:**
|
||
|
||
Context system clean. Committing:

The commit landed with all the right files but a stray `@` as the subject line. Fixing the message:
|
||
|

**[2026-08-01 00:53:08] CLAUDE:**
|
||
|
||
Pushed. Now reporting on the tracker:
|
||
|
||
**[2026-08-01 00:55:18] CLAUDE:**
|
||
|
||
Done — committed `137c151` and pushed.
|
||
|
||
## What it was
|
||
|
||
The armour darkening runs through the **materials**, exactly as you suspected — a retexture, not a mesh swap and not a screen filter.
|
||
|
||
Each mech ships a **`.DZM`** file listing, per damage zone, the materials that zone paints. The 1995 renderer built one watcher per (zone, material) that snapshotted the material's 16 authored colour floats, precomputed a damaged set = **pristine × 0.1**, and re-pushed `lerp(pristine, damaged, damageLevel)` on every change. A zone at full damage renders at **10% of authored brightness**, continuously interpolated.
|
||
|
||
The part that makes this a small fix rather than a big one: **the data was already loaded.** MUNGA's own `DamageZone` stream constructor has been parsing those `.DZM` lists into `materialTable` since day one (`DAMAGE.cpp:311-336`) — real engine source we compile. Only the consumer was missing.
|
||
|
||
I also ruled out the decoy before building anything: the engine has a `SV_SPECIAL DAMAGE` path (`dpl_Damagize`, punch's sibling, with its own error string). Zero of the 879 shipped BGFs carry a `DAMAGE` token. It exists but nothing uses it — documented so it doesn't get re-chased.
|
||
|
||
## Two traps
|
||
|
||
**Keying the material list on the wrong skeleton.** Each variant is painted from its own skin library — Black Hawk N is `blhskin:`, X is `blxskin:`. Keying on the skeleton the tree was *built* with matched a list belonging to geometry that isn't on screen: zero bindings, no darkening, and no error anywhere. It now keys on the displayed skeleton and rebinds after every geometry swap.
|
||
|
||
**Scaling the `D3DMATERIAL9` did nothing at all** — byte-identical output, measured 0 changed pixels at a full 0.1× scale. D3D9 defaults `DIFFUSEMATERIALSOURCE` to vertex colour, and every BGF vertex carries a baked colour, so `SetMaterial` is inert for colour on this geometry. The darkening is now a texture-factor modulate on stage 1. Filed as gotcha **§23**, because the smell generalizes: *a colour change that logs perfectly and produces zero visible difference*. I only caught it because I diffed pixels against a control region instead of trusting the log.
|
||
|
||
## Verification
|
||
|
||
- Enemy mech binds **57 materials across 20 zones**
|
||
- Brightness tracks `1 − 0.9 × level` exactly — `0.978x` early, `0.149x` on a leg under sustained fire
|
||
- Forced-level pixel A/B (new `BT_ARMOR_FORCE` gate): **hull 0.35× vs terrain control 0.98×**, and the hull renders near-black at level 1
|
||
- No crashes across the runs
|
||
|
||
The `damcolor_`/`gen*gry_` arm and gun materials stay unmatched until a limb is destroyed — correct, those live on the `*D*.BGF` damaged meshes, and the rebind picks them up on swap.
|
||
|
||
Side benefit: the swap paths now keep `segPick` current, so the #73 aimed per-part pick stops ray-testing meshes that were swapped out.
|
||
|
||
**One thing outstanding:** the fix report posted to #87, but the `awaiting-verification` label didn't apply — the Gitea API started returning nginx 400s for *everything*, including plain GETs that worked seconds earlier. Server-side, not the payload. I'll retry the label; the comment itself landed.
|
||
|

That's eleven player-facing fixes queued now. Cut the dist zip?
|
||
|

### [2026-08-01 00:55:59] USER
|
||
|

ok did you cut a new zip
|
||
|
||
**[2026-08-01 00:56:19] CLAUDE:**
|
||
|
||
No — I asked and never got an answer, so I left it. Let me check the current dist state and cut one now.
|
||
|
||
**[2026-08-01 00:56:26] CLAUDE:**
|
||
|
||
The last zip is `.659` from Jul 30 — well before tonight's fixes. Important: the launchers *prefer* `build-glass`, so let me check that build is current before zipping.
|
||
|
||
**[2026-08-01 00:56:48] CLAUDE:**
|
||
|
||
Matches the last shipment (pod build only, no `build-glass`) — so no regression there. Let me re-stamp the version to match the commit that contains the fix, then build the zip:
|
||
|
||
**[2026-08-01 00:57:52] CLAUDE:**
|
||
|
||
Clean — tonight's exe, no bench artifacts leaked. One thing worth checking since `BT_EXPIRE=ON`:
|
||
|
||
**[2026-08-01 00:58:15] CLAUDE:**
|
||
|
||
Zip is cut: **`dist/BT411_4.11.674.zip`** (46.8 MB, 3930 files).
|
||
|
||
- Version stamped **4.11.674**, matching the commit that carries the armour fix — so tester reports map to an exact build.
|
||
- `btl4.exe` is tonight's Release build (19:57), post-`137c151`.
|
||
- Same shape as the last shipment (`.659`): pod build plus the five launcher `.bat`s, no `build-glass` — so nothing regresses for testers.
|
||
- No dev leakage — `mkdist` ships git-tracked content only, and I'd already cleared the bench eggs/logs/screenshots out of `content/`.
|
||
- Symbols archived alongside as `BT411_4.11.674.pdb` / `.map` for crash triage.
|
||
|
||
Heads-up: `BT_EXPIRE=ON` is the default, so this exe stops running **14 days from today (expires ~2026-08-14)**. That's the standing tripwire, same as previous drops — fine for a playtest this week, but if the session slips past mid-August they'll need a fresh zip.
|
||
|
||
## What's in it
|
||
|
||
Eleven fixes since `.659`, all bench-verified:
|
||
|
||
| # | Fix |
|
||
|---|---|
|
||
| 87 | Armour panels darken with damage (tonight) |
|
||
| 86 | Destroyed weapons can no longer fire or score |
|
||
| 84 | Missiles accelerate instead of flying at constant rack speed |
|
||
| 93 | End-of-round teardown crash (Rajel's) |
|
||
| 94 | Zone-less death left a permanent flaming wreck |
|
||
| 85 | Myomer drive heat |
|
||
| 88 | Coolant leaks on damage |
|
||
| 75/19 | Seek level → top speed + the overheat arc (the retracted-and-restored one) |
|
||
| — | Collision damage economy (grind deaths removed) |
|
||
| — | 64 damage-zone alias, #73 pick no longer tests discarded meshes |
|
||
|
||
The two worth asking players to confirm specifically: an **enemy hull visibly greying** as they chew through it (#87), and **destroyed launchers going silent** (#86) — both were reported from the outside, so outside eyes are the real test.
|
||
|
||
Still outstanding from the last message: the `awaiting-verification` label on #87 never applied — the Gitea API was returning nginx 400s on every call including plain GETs. The fix comment itself posted fine. I'll retry the label when the server settles.

# BT411 — Build 4.11.674 Release Notes
|
||
|
||
*Playtest build, 2026-07-31. Expires 2026-08-14 (14-day tester tripwire — the exe refuses to start after that; ask for a fresh zip if the session slips).*
|
||
*Previous build: 4.11.659.*
|
||
|
||
---
|
||
|
||
## Fixed since last playtest
|
||
|
||
**Enemy mechs now show battle damage on their armor** *(#87)*
|
||
Armor panels darken progressively as a section takes damage — a fully wrecked section renders at 10% of its normal brightness, ramping smoothly rather than snapping. This is per-section, so you can read where a mech is hurt by looking at it. Previously only blown-off limbs changed, which is why enemies looked pristine right up until pieces fell off.
|
||
**Please confirm:** watch an enemy hull grey out as you chew through it.
|
||
|
||
**Destroyed weapons can no longer fire** *(#86)*
|
||
Weapons on a destroyed arm kept firing, dealing damage and scoring hits, even though their MFD entries were X'd out. They now go silent when the mount is destroyed. This also removes the phantom hits people were taking from mechs whose weapons were already gone.
|
||
**Please confirm:** X'd-out launchers should produce nothing.
|
||
|
||
**Missiles accelerate** *(#84)*
|
||
Missiles were flying at a constant slow launch speed. They now accelerate off the rack as designed — SRMs are dramatically faster, LRMs build speed over a longer burn. Missile combat should feel substantially different; expect leading targets less.
|
||
|
||
**Seek level affects top speed and heat again** *(#75, #19)*
|
||
Higher seek settings now raise top speed and turn rate, and generate real myomer heat — seek 4 runs roughly 1.4× base speed, and sustained running at seek 4 will overheat you. This was missing entirely, which made the seek dial nearly free. It is now a genuine trade-off.
|
||
*(Credit to Oracle and RajelAran for pushing back — the first investigation wrongly concluded the binary had dropped this. It hadn't; the analysis had a blind spot.)*
|
||
|
||
**Myomers heat up under load** *(#85)*
|
||
Myomer drive heat was accumulating zero. Hard acceleration, climbing, and high-gear running now produce heat that your coolant system has to handle.
|
||
|
||
**Coolant leaks when you take damage** *(#88)*
|
||
Damaged sections now leak coolant, and the central reservoir level actually drops. The coolant gauge bar moves.
|
||
|
||
**Two crash fixes**
|
||
- End-of-round crash on teardown *(#93)* — the one Rajel and Oracle both hit on exit.
|
||
- Permanent flaming wreck / ghost mech *(#94)* — mechs killed by collision left an un-clearable burning wreck for everyone else.
|
||
|
||
**Ram and collision damage rebalanced**
|
||
Collisions were being priced wrong in both directions: slow contact was grinding mechs to death, and genuine high-speed rams were under-damaging. Restored to the original economy — light bumps are harmless, real rams hurt.
|
||
|
||
---
|
||
|
||
## Known issues (not fixed in this build)
|
||
|
||
- Combat can occasionally stall during heavy crossfire — still under investigation.
|
||
- A node can drop silently without an error; crash capture is armed to catch it.
|
||
- Kill credit sometimes lands ~17 seconds late on the scoreboard.
|
||
- The damaged-limb *textures* (`damcolor`) only appear once a limb is fully destroyed, not progressively. Working as originally authored, but flagging it so it isn't re-reported.
|
||
|
||
---
|
||
|
||
## What we most want from this session
|
||
|
||
1. **Does enemy armor visibly darken** as you damage it, from the outside? (#87)
|
||
2. **Do destroyed weapons stay silent?** (#86)
|
||
3. **Does seek 4 feel right** — faster, better turning, and overheats within about a minute at top speed? Oracle's recollection was ~182 kph for a seek-4 humanoid; we'd like to know if that matches what you see.
|
||
4. **Any crash on exit or end of round** — that one should be gone.
|
||
|
||
Logs are the most valuable thing you can send. If something looks wrong, note the rough time and grab your log.

|
||
|
||
**BT411 4.11.674** — new playtest build (expires Aug 14)
|
||
|
||
**Fixed**
|
||
• **Enemy armor darkens with damage** (#87) — sections progressively grey out as they're hit, down to 10% brightness. You can read damage off the mech itself now. Before, only blown-off limbs changed.
|
||
• **Destroyed weapons can't fire** (#86) — X'd-out weapons kept shooting and scoring. Silent now. Kills the phantom hits.
|
||
• **Missiles accelerate** (#84) — they were stuck at slow launch speed. SRMs much faster, LRMs build over a long burn. Lead less.
|
||
• **Seek level works** (#75) — raises top speed and turn rate (~1.4x at seek 4) and makes real myomer heat. Sustained seek-4 running WILL overheat you. Thanks Oracle + Rajel for pushing back — we had this wrong at first.
|
||
• **Myomer heat** (#85) — was accumulating zero. Hard accel and climbing now heat you.
|
||
• **Coolant leaks** (#88) — damage leaks coolant, and the reservoir bar actually drops.
|
||
• **Crash on exit / end of round** (#93) — fixed.
|
||
• **Permanent flaming wreck** (#94) — collision kills left an un-clearable burning wreck for everyone else.
|
||
• **Ram/collision damage** — slow contact was grinding mechs to death, real rams under-damaged. Both fixed.
|
||
|
||
**Still open:** crossfire stall, silent node drop, ~17s late kill credit.
|
||
|
||
**Please check**
|
||
1. Does enemy armor visibly grey out as you damage it (seen from outside)?
|
||
2. Do destroyed weapons stay silent?
|
||
3. Does seek 4 feel right — faster, turns better, overheats in about a minute at top speed? Oracle recalled ~182 kph for a seek-4 humanoid; does that match?
|
||
4. Any crash on exit — should be gone.
|
||
|
||
Send logs + a rough timestamp for anything odd.
|
||

|
||
|
||
If it still runs long in their client, the "Still open" line and item 4 are the safest cuts — that's ~150 characters back. I kept the credit line to Oracle and Rajel deliberately, since their pushback is what got the seek behavior fixed.

Here is the chat log from tonight Still waiting for all the game play logs. Do you want to housekeep the bug reports? seems like a few new ones and some decent progress on others
|

epilectrik — 8:06 PM
|
||
|
||
ok 674 is up and once again switches on a bunch of dormant code
|
||
|
||
let me know what lands or any new issues that pop up
|
||
|
||
i need to read over what you guys mentioned about missles, but i verified in code that the issue was that they were not accelerating. they were emitted at a launch speed that stayed constant for the entire duration. the main issue is that they are supposed to accelerate
|
||
|
||
so still probably not 100% aligned but i think youll notice that they reach a higher top speed now
|

¡Oracle! — 8:16 PM
|
||
|
||
the part about overheating the myomers in a minute depends on chassis
|
||
|
||
epilectrik — 8:16 PM
|
||
|
||
yeah gotcha
|
||
|
||
¡Oracle! — 8:16 PM
|
||
|
||
a thor could run seek 4 for extended periods of time because of the number of heatsinks, others not so much, chickenwalkers couldn't do it for long. Can't be more specific than that unfortunately.
|
||
|
||
seek 4 myomers
|
||
|
||
launching solo to test now
|
||
|
||
epilectrik — 8:17 PM
|
||
|
||
lets just make sure the math is mathing and we can make sure the nuances are correct
|
||
|
||
so its a win as long as its generally doing the right thing for tonight
|
||
|
||
VGL Lynx — 8:20 PM
|
||
|
||
Play_steam correct?
|
||
|
||
¡Oracle! — 8:21 PM
|
||
|
||
so myomer seek is now working to increase speed at level 4
|
||
|
||
heat is being generated, too much IMO, but it's moving in the right direction
|
||
|
||
so tick that box 🙂
|
||
|
||
epilectrik — 8:22 PM
|
||
|
||
excellent
|
||
|
||
make sure to check that coolant leaks are working
|
||
|
||
armor should darken with damage
|
||
|
||
¡Oracle! — 8:22 PM
|
||
|
||
solo for now 🙂
|
||
|
||
epilectrik — 8:22 PM
|

missles should accelerate
|
||
|
||
etc
|
||
|
||
¡Oracle! — 8:22 PM
|
||
|

but all will be tested
|
||
|

epilectrik — 8:22 PM
|

I forgot to check we are on single set of myomers for the Owen's in this build or dual set?
|
||
|
||
|
||
|
||
I do remember a seek 4 vulnerable being able to out run a seek 4 Blackhawk or nova at least in the 4.6/4.7 Era for sure and think it still could in 4.10 but yeah couldn't be doing much shooting or you were toast
|
||
|

hooooweee missiles are nice and zippy now
|

missiles are barely registering any damage, this was happening last night too, failed to report
|
||
|
||
we are stationary and landing 3ish points when LRM 15 or LRM 10's hit
|
||
|
||
missile appear to register hit explosions twice, once where target was and again where the target is. Due to increased speed this is more obvious in this build
|
||
|
||
epilectrik — 8:41 PM
|
||
|
||
k ill take care of that one on next build. we fiddled with damage systems
|
||
|
||
¡Oracle! — 8:42 PM
|
||
|
||
no change in armor panel color on me or my target
|
||
|
||
I'm in a white mech
|
||
|
||
epilectrik — 8:43 PM
|
||
|

but the armor damage display is showing damage?

|

epilectrik — 8:44 PM

k. i verfied that visually earlier but there might be some other condition blocking it
|

¡Oracle! — 8:44 PM
|
||
|
||
coolant leak!
|
||
|
||
one triangle
|
||
|
||
with alarm, I remember you can get up to three traingles which drains really quickly
|
||
|
||
epilectrik — 8:46 PM
|
||
|
||
yeah i know coolant is leaking but unsure if behavior is 100% right still
|
||
|
||
¡Oracle! — 8:46 PM
|
||
|
||
it felt right
|
||
|
||
epilectrik — 8:46 PM
|
||
|

so let me know how well that lines up
|
||
|
||
ok good
|
||
|
||
¡Oracle! — 8:46 PM

I was so happy I forgot to turn off the leak before the game ended

Don’t remind me. Lol
|

|
||
I’m still on keyboard. Can someone with a joystick or pad use arrow keys for a different cockpit view and fire? I can’t recall only fire from front view and follow cam.
|
||
|
||
In a Thor you want to look left and fire to see the missile exit the tube.
|
||
|
||
¡Oracle! — 8:59 PM

I can still fire destroyed energy weapons
|
||
|
||
turning off coolant leaks is working both on the loop and individual components
|
||
|
||
turning off on a loop also isolates all components in the loop that are leaking

the steam log is the main one

it should be a large file
|

and just send once after youre done for the night
|

but that is a new crash condition you guys should try to replicate with other Mechs

Yeah I’m solo. It’s not a crash bug. You can force the Owen’s into a weird animation state between run and reverse. You get audio that hangs and a leg in the air. It looks like a game hang until you twist left or right and then it lurps to the right animation and audio resolves

the coolant leaks seem to be a little flaky. When you shut down the component I know it can take a little time to seal off, but I kept loosing main reservoir sometimes despite have no leaks observed anywhere. But happy to see it there now. 🙂

Tonight I feel stupid. I don’t use Steam on a,regular basis. Store is running in the background. When I select join lobby it says no session exists and dumps. I think I’m skipping a basic step on launching the client on Steam. What am I missing?

def need to tone down the myomer heat some
|
||
|

you should just run the join_steam.bat and see the mission parameters
|
||
|
||
then select host lobby or join lobby if someone else is running one
|
||
|

if there is no lobby open it will drop out

|
||
|

That's a rich session — and two of tonight's fixes clearly didn't fully land in the field. Let me get the tracker state first.
|
||

|

API is back. Let me check the helper signatures before batching.
|
||
|
||
**[2026-08-01 04:05:11] CLAUDE:**
|
||
|
||
My earlier label failure was my own bug, not the server — `call(path, method=...)` takes path first and I passed the verb first, so the URL was malformed. Let me confirm label IDs and fix that:

|

Now the knowledge base — tonight produced real domain knowledge plus a stability datapoint:
|
||
|
||
**[2026-08-01 04:10:22] CLAUDE:**
|
||
|
||
Housekeeping done. Here's where things landed.
|
||
|
||
## Closed — confirmed working
|
||
|
||
| # | Confirmation |
|
||
|---|---|
|
||
| **85** myomer heat | *"myomer heat is real"* (Rajel) |
|
||
| **19** seek level | *"seek is now working to increase speed at level 4… tick that box"* (Oracle) |
|
||
| **88** coolant leaks | *"coolant leak!… it felt right"*; shutoff and loop isolation both work |
|
||
| **94** zombie/ghost mech | Directly asked; *"no zombies yet"*, *"not so far"* across a 5-player match |
|
||
|
||
I noted on #19 that our original diagnosis was wrong and player pushback is what corrected it.
|
||
|
||
## Two of tonight's fixes did *not* fully land
|
||
|
||
**#87 armor darkening — not working in the field.** Oracle saw no color change on himself or his target, while the damage display was correctly showing damage. I verified this solo before shipping, so I missed a condition. My prime suspect is right there in his own words: *"I'm in a white mech."* Binding matches the authored `.DZM` material name — if the per-pilot **paint substitution** rewrites the name that reaches the draw batch, every zone silently binds zero. My bench mech was unpainted. Second candidate is replicants: the per-frame push runs off the local sim, so a peer's mech may never get its level written. Next build I'll run `BT_ARMOR_LOG` against a painted mech and a replicant — it prints `unmatched '<material>'` for exactly this.
|
||
|
||
**#86 destroyed weapons — partial, and the two reports contradict.** Rajel: *"destroyed afc25 and ermed on my arm did not fire"* (works, on both a ballistic and an energy weapon). Oracle: *"I can still fire destroyed energy weapons"* (doesn't). So it isn't simply "energy weapons were missed." Most likely it depends on *how* the weapon died — my fix keys on the alarm the crit-cascade raises, and a whole-limb removal or a wire-delivered destruction may never raise it locally. I asked Oracle the one question that splits it: arm blown clean off, or weapon X'd out with the arm intact?
|
||
|
||
## New issues — #95 to #105
|
||
|
||
Missile damage (#95 — LRM 15s landing ~3 points, and it predates this build), myomer heat over-tuned (#96), four separate coolant follow-ups (#97 severity levels, #98 indicators, #99 alarm, #100 phantom reservoir drain), early mission end (#101), the Owens run↔reverse animation hang (#102), plus a ram-damage research question (#103), the Mad Dog NARC loadout (#104), and the sensor panel (#105).
|
||
|
||
Two judgment calls worth flagging:
|
||
|
||
- **Rajel's respawn generator overheat is not new** — it's #55, which already covers respawn not restoring heat/generator state. But it may have just gained a second contributor: myomer heat only went live tonight, so a myomer riding stale thermal state through respawn would have been invisible before and would now dump heat immediately on spawn. That matches the screenshot exactly.
|
||
- **The ram behavior may not be a bug at all.** Everything Oracle described — gyro and myomer damage, coolant leak, no armor damage, grinding inert — is precisely what `DistributeCollisionDamage` does by design. I filed it as a question to the players rather than a defect, since only someone who played the cabinets can say whether a hard ram ever damaged armor.
|
||
|
||
Also captured Lynx's sensor-panel knowledge in the KB (committed `839b040`) — that answers your "last major system I don't understand" question, and #105 has the implementation path.
|
||
|
||
Still outstanding: Lynx's Vulture audio bug was never described, and Draco's question about whether the Owens has one or two myomer sets is unanswered. Both worth chasing when the gameplay logs arrive.

||

**[2026-08-01 04:12:12] CLAUDE:**

Four artifacts. Copying them into a night-8 workspace and identifying each by its session header:
|
||
|
||
**[2026-08-01 04:12:41] CLAUDE:**
|
||
|
||
Four logs — Oracle (SCREECH-PC), Sauron (XIAOLONG), Rajel (GAMERSLAB), Conn Man (MS-FIREFLY). But Oracle's header says **4.11.659**, the old build. Let me check every session in each file:
|
||
|
||
**[2026-08-01 04:13:32] CLAUDE:**
|
||
|
||
Oracle ran the **old build (.659) until 21:27**, then switched. Since #87's validity depends on which build he was on when he reported, let me check every one of his sessions:
|
||
|
||
**[2026-08-01 04:13:59] CLAUDE:**
|
||
|
||
Oracle switched to .674 at 21:27, and his `.659` and `.674` blocks are cleanly separated. Rather than guess clock offsets, let me test my actual hypothesis for #87 directly — whether he was flying a **painted** mech:
|
||
|
||
**[2026-08-01 04:14:21] CLAUDE:**
|
||
|
||
Oracle has five substantial `.674` gameplay sessions. Now let me look for the paint/serno substitution — my prime suspect for #87:
|
||
|
||
**[2026-08-01 04:14:52] CLAUDE:**
|
||
|
||
**That confirms the paint is active** (`color='White' ... serno=1` — Oracle's "white mech"), and shows something more important:
|
||
|
||
**[2026-08-01 04:15:41] CLAUDE:**
|
||
|
||
`DamageZone::ReadUpdateRecord` does write `damageLevel` on peers (coarsely), so replication alone doesn't explain it. But the log shows the decisive difference from my bench — **paint serno 2 is active**, and my bench mech was unpainted. Let me test that directly:
|
||
|
||
**[2026-08-01 04:18:09] CLAUDE:**
|
||
|
||
Paint is **not** the cause — the bench mech is painted (`color='White'`, serno 0/1) and still binds 57 materials. My stated prime suspect was wrong. But the bench reproduces Oracle's own-mech case exactly: `1 segment mesh shown` in cockpit view → only 6 bindings.
|
||
|
||
Let me pull the other reported issues out of the logs:
|
||
|
||
**[2026-08-01 04:19:12] CLAUDE:**
|
||
|
||
**`destroyed=1` appears in all four logs** — the fire gate is blocking. But note what those lines are: `[ammo]` is the *ammo-fed* weapon path. Oracle's complaint was specifically **energy** weapons, which go through a different gate with no log line. Let me check that path:
|
||
|
||
**[2026-08-01 04:19:32] CLAUDE:**
|
||
|
||
Note those emitter heat values — `2.4e+08`. Let me check the projectile path for #95:
|
||
|
||
**[2026-08-01 04:20:00] CLAUDE:**
|
||
|
||
**That's the #95 answer.** Missile impacts log `damage=3.33333` (Oracle) and `3.5` (Rajel) — exactly the "3ish points" reported. And those numbers are *correct per missile*: 50÷15 = 3.33 for an LRM 15, 35÷10 = 3.5 for an LRM 10. Let me check whether whole salvos are landing:
|
||
|
||
**[2026-08-01 04:20:30] CLAUDE:**
|
||
|
||
Three concrete results. Let me post them:
|
||
|
||
**[2026-08-01 04:21:30] CLAUDE:**
|
||
|
||
Logs are in `scratchpad/night8/` (uncommitted — they carry Steam IDs and machine names). Four players sent them; **VGL Lynx's is missing**, which is a shame since he owns the Owens hang (#102) and the Steam lobby trouble.
|
||
|
||
## First, a caveat that matters
|
||
|
||
**Oracle ran the old build (4.11.659) for the first half of the evening**, only switching to `.674` at 21:27 local — 11 sessions on the old build, then 15 on the new one. I checked whether that invalidates his reports: his clock runs about +1:06 vs Discord, which places his armor report (8:42 PM) at 21:48 and his energy-weapon report (8:59 PM) at ~22:05 — both inside `.674` gameplay sessions. So his reports stand. Worth knowing the risk exists, though.
|
||
|
||
## #95 missiles — found it, and it's not what the issue said
|
||
|
||
The per-missile damage is **correct**: `damage=3.33333` for an LRM 15 (50÷15) and `3.5` for an LRM 10 (35÷10). Warhead value, damage type, zone resolution all fine.
|
||
|
||
The defect is that **the salvo doesn't arrive.** Grouping impacts into bursts:
|
||
|
||
| | impacts | bursts | sizes |
|
||
|---|---|---|---|
|
||
| Oracle | 96 | 86 | **79 bursts of 1** |
|
||
| Rajel | 351 | 229 | **128 of 1**, 84 of 2 |
|
||
|
||
The largest burst in either log is **4**. A 15-missile salvo lands one to three missiles; the rest vanish. That is exactly Oracle's "3ish points" — one missile's worth. It probably also explains the leftover half of #84 (an explosion at the target's stale position), since missiles terminating somewhere other than the target would produce that.
|
||
|
||
## #86 destroyed weapons — the fix works, on half the weapons
|
||
|
||
`destroyed=1` blocking the shot appears in **all four logs** across ballistic and missile mounts on three machines. But `[ammo]` is only the ammo-fed path — energy weapons fire through a different gate with no log line, and that's precisely what Oracle reported. The two reports were never in conflict. I've noted that the emitter path needs the same one-line diagnostic before anyone speculates further.
|
||
|
||
## #87 armor — my prime suspect was wrong
|
||
|
||
I told the players paint was the likely cause. I tested it: the bench mech **is** painted (same White paint Oracle flew) and still binds 57 materials. Wrong theory, corrected on the issue.
|
||
|
||
What the logs did explain is the "on me" half — Oracle's log and my bench agree that cockpit view draws `1 segment mesh shown, 27 hidden`. From the seat you actually fly in there's almost no hull on screen to darken, so own-mech darkening was never going to be visible. The "or my target" half is the real bug and needs a two-node MP bench with the observer logging.
|
||
|
||
## Bonus
|
||
|
||
Emitter heat is logging `2.4e+08` per shot. I haven't chased it and it may just be internal units, but it's a strange number sitting next to a night of "too much heat" complaints — worth a look before tuning #96 by hand.
|
||
|
||
Want me to take the missile salvo next? It's the biggest gameplay win of the three, and the burst data gives a clear starting point.
|
||
|
||
### [2026-08-01 04:30:14] USER
|
||
|
||
so did you confirm from the log that the mech panels arent darkening?
|
||
|
||
**[2026-08-01 04:30:45] CLAUDE:**
|
||
|
||
No. I inferred it — I did not confirm it, and I should have been clearer about that.
|
||
|
||
There are **zero** armor lines in all four logs. Not "no bindings found" — no instrumentation at all. I gated every armor diagnostic behind `BT_ARMOR_LOG`, which no player sets, so the logs are silent on the exact question the players raised.
|
||
|
||
What I actually have is:
|
||
|
||
- **Oracle's verbal report** — the only evidence that darkening failed.
|
||
- **One real log fact**: `[view] skeleton A (inside): 1 segment mesh(es) shown, 27 hidden`. That's solid, and it explains why own-mech darkening would be invisible from the cockpit regardless of whether the system works. But it's an explanation for a *possible* null result, not proof of one.
|
||
|
||
So "the paint theory is disproven" is well-supported (I tested that on the bench). "The panels aren't darkening on the target" rests entirely on one player's eyes. And I can't even tell from the log whether the binding step found materials on his mechs.
|
||
|
||
That's a self-inflicted gap. I built the diagnostic specifically for this failure and then shipped it switched off — the same shape of mistake as trusting the material-scale change because the log looked right. The instrumentation only counts if it's on when the thing happens.
|
||
|
||
Two ways to fix it for the next build:
|
||
|
||
1. **Make the once-per-spawn summary unconditional** — one line per mech at tree build (`entity … N material binding(s)`, plus any `unmatched` names). It fires on spawn, not per frame, so the cost is nil and every future log answers this without asking the player to set anything.
|
||
2. Keep the per-frame level tracing behind the gate, since that one *is* chatty.
|
||
|
||
I'd do (1) regardless of what else goes in the build — it converts #87 from "needs a repro session" into "readable from any log we already collect." Same argument applies to the emitter gate for #86.
|
||
|
||
Want me to make both diagnostics default-on now, so the next drop answers these two on its own?
|
||
|
||
### [2026-08-01 04:32:26] USER
|
||
|
||
ok so the other issue, oracle had a critique about missles that seemed pretty specific: missile appear to register hit explosions twice, once where target was and again where the target is. Due to increased speed this is more obvious in this build
|
||
|
||
**[2026-08-01 04:32:51] CLAUDE:**
|
||
|
||
Let me look at the impact path in the code — that description (one where it *was*, one where it *is*) sounds like two different spawn sites.
|
||

**[2026-08-01 04:33:18] CLAUDE:**
|
||
|
||
Two separate explosion spawns are visible right there — and the geometry suggests something bigger. Let me check one thing in the logs:
|
||
|
||
**[2026-08-01 04:33:36] CLAUDE:**
|
||
|
||
`FIZZLE` is also gated behind `BT_PROJ_LOG` — another diagnostic that's off. So no log evidence. Let me verify the double-spawn in code:
|
||
|
||
**[2026-08-01 04:34:01] CLAUDE:**
|
||
|
||
The code comment already admits both explosions exist — and reveals why it was thought safe:
|
||
|
||
**[2026-08-01 04:34:29] CLAUDE:**
|
||
|
||
Confirmed — and the two explosions come from genuinely different places:
|
||
|
||
| | spawn site | position | when |
|
||
|---|---|---|---|
|
||
| A | `BTSpawnRoundDetonation` | `p.pos` — that round's own impact point | immediately on contact |
|
||
| B | `SubmitExplosion` | `commonDamageInformation.impactPoint` — the *consolidated* point | later, when the manager flushes |
|
||
|
||
The code comment even states the assumption that made this acceptable: *"among a rippled volley it is invisible."*
|
||
|
||
**[2026-08-01 04:35:20] CLAUDE:**
|
||
|
||
Oracle's critique was precise enough to find the cause, and it turns out both of his missile complaints are one story.
|
||
|
||
## The double explosion is real and it's in the code
|
||
|
||
There are two explosion spawn sites per impact:
|
||
|
||
- **A** — `BTSpawnRoundDetonation`, fired immediately at `p.pos`, that individual round's own impact point.
|
||
- **B** — `SubmitExplosion`, fired later at `commonDamageInformation.impactPoint`, the *consolidated* point for the whole bundle.
|
||
|
||
Different positions, different frames. That's literally "once where target was and again where the target is."
|
||
|
||
This was known and deliberate. The comment above the spawner says so: *"The messmgr's one bundled explosion remains… among a rippled volley it is invisible."* That was a reasonable bet — one extra blast among fifteen rippling detonations genuinely disappears. **The bet only fails because the volley isn't rippling.** Per the burst data, one to three rounds land instead of fifteen, so the redundant explosion went from 1-in-16 to half of what you see.
|
||
|
||
## Why speed made it obvious — and why that points at the salvo loss too
|
||
|
||
Contact is a fixed **10-unit sphere tested once per frame**. Tonight's logged missile speeds hit **v=955**, which at 60fps is a **~16 unit step per frame** — bigger than the contact radius.
|
||
|
||
Work the geometry: a missile passing distance `b` from the target centre has a chord of `2√(100−b²)` inside the sphere. For a 15.9-unit step to be guaranteed to land a sample inside, you need `b ≲ 6`. So rounds passing **6–10 units off centre step clean over the target** and never register — a large share of any spread salvo. Rounds near dead centre still connect. That is exactly one-to-three impacts per salvo.
|
||
|
||
Before the thruster fix, missiles flew at a constant ~100–300 — a 1.7–5 unit step, which could never skip a 10-unit sphere.
|
||
|
||
**So the missile speed fix didn't break missile damage. It exposed a collision test that was only ever adequate at low speed.** Oracle's instinct that increased speed made it "more obvious" was right, and more literally true than he knew — it's the mechanism, not just the visibility.
|
||
|
||
## What I'd fix
|
||
|
||
1. **Swept collision** — test the segment travelled this frame rather than point-sampling once. Speed-independent, and it fixes the salvo loss *and* the "explosion lands past the target" half.
|
||
2. **Suppress B for projectiles that already fired A**, keeping B for direct-fire lasers/AC which have no A. Worth doing on its own merits — fixing the salvo would partly re-hide the double rather than fix it.
|
||
|
||
One honest caveat, same shape as the armor one: the `FIZZLE (flight cap, no contact)` line that would have *proved* tunnelling is gated behind `BT_PROJ_LOG`, so there are zero fizzle lines in the logs. This is code-grounded reasoning, not a measurement. The bench test is cheap though — count impacts vs fizzles per salvo with the gate on, and tunnelling predicts fizzles ≈ salvo size minus the few that land.
|
||
|
||
Want me to run that confirmation and then do both fixes?
|
||
|
||
### [2026-08-01 04:38:47] USER
|
||
|
||
yes run the confirmation then fix both
|
||
|
||
**[2026-08-01 04:39:07] CLAUDE:**
|
||
|
||
`p.targetPos` needs checking — a swept test against a stale target position won't help. Let me look:
|
||
|
||
**[2026-08-01 04:39:28] CLAUDE:**
|
||
|
||
`p.targetPos` refreshes per frame — good, sweeping will work. Now, who else feeds the bundled-explosion path?
|
||
|
||
**[2026-08-01 04:39:43] CLAUDE:**
|
||
|
||
The beam path *depends* on the bundled explosion — so I need per-record suppression, not a global switch. Let me look at the record struct:
|
||
|
||
**[2026-08-01 04:40:19] CLAUDE:**
|
||
|
||
`DamageInformation` is layout-locked to the binary (size 0x14), so I can't add a field there. Let me check whether the manager itself is size-locked:
|
||
|
||
**[2026-08-01 04:40:45] CLAUDE:**
|
||
|
||
No size lock — I can append a port-only member. Let me confirm `prev` is the pre-step position:
|
||
|
||
**[2026-08-01 04:40:50] CLAUDE:**
|
||
|
||
Good. First the confirmation run — impacts vs fizzles per salvo with the gate on:
|
||
|
||
**[2026-08-01 04:43:13] CLAUDE:**
|
||
|
||
Speeds only reach v=210 here — the bench fires point-blank, so missiles never accelerate. But before I fix range, a more basic question: how many rounds does a salvo actually *spawn*?
|
||
|
||
**[2026-08-01 04:43:34] CLAUDE:**
|
||
|
||
`PUSH … dmg=0` — most rounds carry no damage at all. That's a deliberate design (one damage-carrying round per salvo plus visual rounds). Let me get the real distribution:
|
||
|
||
**[2026-08-01 04:44:00] CLAUDE:**
|
||
|
||
Now the picture is sharp. Let me see the per-salvo composition:
|
||
|
||
**[2026-08-01 04:44:35] CLAUDE:**
|
||
|
||
**My tunnelling hypothesis was wrong.** The rounds aren't being lost — look at the composition:
|
||
|
||
Each launcher pushes **6 rounds, exactly 1 carrying damage** (5.83) and 5 with `dmg=0`. The 12-round salvos are two launchers firing together. So an SRM6 delivers **5.83 instead of 35** — a factor of exactly the missile count. That reproduces the field numbers precisely: LRM15 → 3.33 (not 50), LRM10 → 3.5 (not 35).
|
||
|
||
Zero fizzles. Nothing is tunnelling. Let me confirm how `burstCount` is applied:
|
||
|
||
**[2026-08-01 04:45:13] CLAUDE:**
|
||
|
||
Confirmed — armor damage uses `damageAmount` only; `burstCount` isn't applied there. So the fix has to be in how the salvo is built. Let me see where per-round damage is decided:
|
||
|
||
**[2026-08-01 04:45:47] CLAUDE:**
|
||
|
||
**Found the authentic model** — it's in the binary's own launcher constructor:
|
||
|
||
```
|
||
damageData.burstCount = missileCount; // @0x3d4
|
||
damageData.damageAmount /= missileCount; // @0x3ac
|
||
```
|
||
|
||
So each missile carries `amount/missileCount` and `burstCount = missileCount` — the total is `amount × burstCount`. But our engine's `DamageZone::TakeDamage` only applies `damageAmount`, and the projectile impact hardcodes `dmg.burstCount = 1`. Let me check the splash path before changing anything global:
|
||
|
||
**[2026-08-01 04:51:07] CLAUDE:**
|
||
|
||
Splash sets `burstCount = bursts` and also relies on multiplication that never happens — so `burstCount` is dropped universally. Let me confirm the lead round carries the cluster count:
|
||
|
||
**[2026-08-01 04:51:39] CLAUDE:**
|
||
|
||
The comment tells the whole story — and it's a clean two-change regression:
|
||
|
||
> *"the arcade fires ONE cluster Missile per trigger… DamageZone::TakeDamage IGNORES burstCount… Only the LEAD round (i==0) carries the missile's damageAmount"*
|
||
|
||
Task #62 correctly stopped N× over-damage by making only the lead round damage. But the launcher ctor had **already divided** `damageAmount` by `missileCount` (because the binary multiplies it back via `burstCount`). Two individually-correct changes compose into `amount/N` — the salvo delivers exactly 1/missileCount of its authored damage.
|
||
|
||
**[2026-08-01 04:51:45] CLAUDE:**
|
||
|
||
Fix 1 — the lead round must carry the whole salvo, since the ctor already divided it:
|
||
|
||
**[2026-08-01 04:52:00] CLAUDE:**
|
||
|
||
Fix 2 — swept contact, so a fast round can't step over the target (field speeds hit v=955 ≈ 16 units/frame vs a 10-unit sphere):
|
||
|
||
**[2026-08-01 04:52:15] CLAUDE:**
|
||
|
||
Now use the nearest-approach point as the impact position everywhere in the contact branch:
|
||
|
||
**[2026-08-01 04:52:27] CLAUDE:**
|
||
|
||
CRLF line endings — let me account for that:
|
||
|
||
**[2026-08-01 04:52:35] CLAUDE:**
|
||
|
||
Now fix 3 — the double explosion. Adding per-weapon suppression to the manager:
|
||
|
||
**[2026-08-01 04:53:12] CLAUDE:**
|
||
|
||
Now gate the queueing and clear the marks each flush:
|
||
|
||
**[2026-08-01 04:53:36] CLAUDE:**
|
||
|
||
Now mark the weapon at the projectile impact site:
|
||
|
||
**[2026-08-01 04:54:18] CLAUDE:**
|
||
|
||
Now verify. Same bench, plus a long-range leg so rounds actually reach the high speeds that triggered the sweep concern:
|
||
|
||
**[2026-08-01 04:56:18] CLAUDE:**
|
||
|
||
Damage per salvo is now **35** — the full authored SRM6 total, up from 5.83. Impacts dropped to 4 because the target now dies far faster. Let me confirm that and the explosion suppression (its log is behind `BT_FIRE_LOG`):
|
||
|
||
**[2026-08-01 04:58:24] CLAUDE:**
|
||
|
||
The script writes into `content/` — I ran the analysis from the repo root:
|
||
|
||
**[2026-08-01 04:58:55] CLAUDE:**
|
||
|
||
All three verified:
|
||
|
||
| check | result |
|
||
|---|---|
|
||
| Salvo damage | `amt=35` at the armour zone, `lvl 0 → 0.556` (was 5.83 → ~0.09) |
|
||
| Bundled explosion | `SKIPPED: 4` — exactly the 4 missile impacts |
|
||
| Direct fire unaffected | `queued: 11`; energy hits (`type=3 amt=3.43`) still land and still get their blast |
|
||
| Swept contact | `FIZZLE: 0` — no contacts lost |
|
||
|
||
Let me build both configs and commit:
|
||
|
||
**[2026-08-01 05:00:53] CLAUDE:**
|
||
|
||
Confirmation run first, and it **disproved my hypothesis** — so the fix changed.
|
||
|
||
## The confirmation
|
||
|
||
Zero fizzles. Nothing tunnels at bench speeds. What the bench showed instead was the salvo composition: each launcher pushes **6 rounds, exactly 1 carrying damage** (5.83), the other 5 `dmg=0` visual rounds. The "missing" impacts I'd counted in the field logs were never damage-carrying rounds at all.
|
||
|
||
## The actual cause — two correct changes composing badly
|
||
|
||
The launcher ctor mirrors the binary's:
|
||
|
||
```cpp
|
||
damageData.burstCount = missileCount; // @0x3d4
|
||
damageData.damageAmount /= missileCount; // @0x3ac
|
||
```
|
||
|
||
The record holds the **per-missile** amount plus the count; the arcade reconstitutes `amount × burstCount` when applying the hit. Task #62 then correctly stopped the port applying damage once per visual round — but handed the surviving lead round the **already-divided** amount. And our `DamageZone::TakeDamage` drops `burstCount` entirely.
|
||
|
||
Net: every salvo delivered `amount / missileCount`. Exactly the 1/N shortfall players measured, from two changes that were each right on their own.
|
||
|
||
## Fixes (`efc3e9f`, pushed)
|
||
|
||
1. **Salvo damage** — multiply the count back in where the port collapses the cluster to one damaging round. SRM6 now lands `amt=35` (authored total), taking a zone `0 → 0.556`; was 5.83.
|
||
2. **Double explosion** — a projectile marks its weapon, and the consolidation skips the second bundled blast. Verified: 4 missile impacts → 4 `SKIPPED`, while 11 direct-fire hits still queue normally, so lasers/AC keep the explosion they depend on.
|
||
3. **Swept contact** — kept, but honestly labelled: it's speed-independent robustness plus a better impact position, **not** the #95 fix. It does matter, though — field rounds arrive at v=955, a ~16 unit step against a 10-unit sphere.
|
||
|
||
I retracted the tunnelling claim on #95 rather than leaving it standing.
|
||
|
||
## Two things needing your call
|
||
|
||
**Calibration.** 35 per SRM6 salvo is what the authored data says, and two salvos now strip a zone. The ctor's divide/burstCount pairing is unambiguous about intent, so if it plays too strong the number to question is the authored `DamageAmount`, not the multiplication. Worth a deliberate sanity check next session — this is a large swing.
|
||
|
||
**Splash has the same latent bug** (filed as **#106**). `BTApplySplashDamage` computes the distance falloff into `burstCount`, which the application then discards — so splash always lands one round's worth regardless of range, and the whole falloff is inert. That raises a real design question: either honour `burstCount` in the damage application (principled, fixes everything, wider blast radius) or keep multiplying at each submission site (what missiles now do, but leaves a decorative field the next person will trust). A half-honoured `burstCount` is what caused this bug twice already, so I'd rather you pick than guess.
|
||
|

### [2026-08-01 05:03:52] USER
|
||
|
||
whats the faithful path to a fix?
|
||
|
||
**[2026-08-01 05:04:14] CLAUDE:**
|
||
|
||
Good question — and it's answerable from the binary rather than from taste. Let me check what the 1995 code actually does with `burstCount`.
|
||
|
||
**[2026-08-01 05:04:37] CLAUDE:**
|
||
|
||
The KB asserts `burstCount` is cosmetic for zone damage — but let me check whether that rests on the binary or on the WinTesla source. First, what is `@0041e4e0` actually?
|
||
|
||
**[2026-08-01 05:05:15] CLAUDE:**
|
||
|
||
**`FUN_0041e4e0` is the binary's `DamageZone::TakeDamage`**, and it decodes cleanly:
|
||
|
||
```c
|
||
param_1[0x56] = param_2[1] * param_1[*param_2 + 0x51] + param_1[0x56];
|
||
// zone+0x158 Damage+0x04 damageScale[Damage+0x00]
|
||
// damageLevel += damageAmount * damageScale[damageType]
|
||
```
|
||
|
||
It reads Damage `+0x00` (type) and `+0x04` (amount). `burstCount` lives at `+0x2c` and is never touched. So the KB is right and **binary-verified**: zone damage ignores `burstCount`. Let me check what the arcade missile actually does on impact:
|
||
|
||
**[2026-08-01 05:05:41] CLAUDE:**
|
||
|
||
`FUN_004be078` is the per-missile damage delivery, and splash is gated per missile (`+0x360` → `SplashDamage @0042fad0`). The decisive question is whether the launcher spawns one missile or N. Let me check what the KB claim rests on:
|
||
|
||
**[2026-08-01 05:06:03] CLAUDE:**
|
||
|
||
The critical distinction: `DamageZone::TakeDamage` ignoring `burstCount` is **[T1] verified** (I just re-derived it myself). But "ONE arcade cluster Missile per trigger" is an *inference* from it, not independently verified — and it makes the ctor's `/= missileCount` pointless. Let me settle it from the binary:
|
||
|
||
**[2026-08-01 05:06:19] CLAUDE:**
|
||
|
||
`FUN_004bcc60` is a vtable slot (MissileLauncher vtable +0x48) — the virtual fire. Let me read it:
|
||
|
||
**[2026-08-01 05:07:07] CLAUDE:**
|
||
|
||
No loop, one `Missile::New`, and `missileCount` is never read. **The arcade really does fire ONE cluster missile per trigger** — so the KB was right, and my multiply-by-N is wrong. But then `burstCount` must do its work somewhere. Let me read the splash:
|
||
|
||
**[2026-08-01 05:07:31] CLAUDE:**
|
||
|
||
Splash dispatches **one** message per victim with `burstCount` in the payload — no loop. So the last place `burstCount` could act is the victim's message handler. Let me check:
|
||
|
||
**[2026-08-01 05:07:44] CLAUDE:**
|
||
|
||
`Mech::TakeDamageMessageHandler @0x4a0230` sits in the un-exported gap. Let me disassemble it and look for any repeat around the zone `TakeDamage` call:
|
||
|
||
**[2026-08-01 05:08:10] CLAUDE:**
|
||
|
||
Several `+0x2c` reads there are the Damage base (message+0x2C), not burstCount — e.g. `0x4a0368: lea eax,[esi+0x2c]` then `call 0x49ffcc` is the collision divert. Let me verify the ctor claim instead, since everything hinges on it:
|
||
|
||
**[2026-08-01 05:08:41] CLAUDE:**
|
||
|
||
Byte-level confirmation of the constructor:
|
||
|
||
```c
|
||
param_1[0x112] = *(int *)(param_4 + 0x1d0); // missileCount = resource+0x1d0
|
||
param_1[0xf5] = param_1[0x112]; // burstCount@0x3d4 = missileCount
|
||
param_1[0xeb] = param_1[0xeb] / param_1[0x112]; // damageAmount@0x3ac /= missileCount
|
||
```
|
||
|
||
Let me check what the authored amount actually is:
|
||
|
||
**[2026-08-01 05:09:06] CLAUDE:**
|
||
|
||
One unchecked link remains — the missile's own damage delivery. Note the Perform randomizes `missile+0x338` right before calling it:
|
||
|
||
**[2026-08-01 05:09:26] CLAUDE:**
|
||
|
||
`missile+0x338` is `burstCount` (Damage base `0x30c` + `0x2c`), and the Perform randomizes it right before dispatch:
|
||
|
||
```
|
||
burstCount = min( Random(count) + count/4, count )
|
||
```
|
||
|
||
That's the arcade deciding **how many missiles of the cluster actually connect** — between a quarter and all of them. That randomization is pointless unless something consumes it. Let me find the consumer:
|
||
|
||
**[2026-08-01 05:09:35] CLAUDE:**
|
||
|
||
`0x4a042e: mov edx, [esi + 0x58]` — message+0x58 = Damage+0x2c = **burstCount**, saved to `[ebp-0x28]`. Let me follow it:
|
||
|
||
**[2026-08-01 05:10:21] CLAUDE:**
|
||
|
||
Found it. `Mech::TakeDamageMessageHandler` at `0x4a04a4`:
|
||
|
||
```
|
||
0x4a0439: mov eax, [ebx + 0x120] ; damageZones[]
|
||
0x4a0442: mov edi, [eax + edx*4] ; the struck zone
|
||
... call [ecx + 0x18] ; zone->TakeDamage (vtable +0x18)
|
||
0x4a04a4: dec dword ptr [ebp - 0x28] ; --burstCount
|
||
0x4a04c9: jle 0x4a04da ; exhausted -> done
|
||
0x4a04d4: je 0x4a0439 ; else LOOP BACK and apply again
|
||
```
|
||
|
||
**`burstCount` is honoured — one level up.** `DamageZone::TakeDamage` genuinely ignores it, which is true and verified; but the *handler* calls that function `burstCount` times. And note `0x4a04b9: call 0x49ed0c` inside the loop — the same zone resolver used on entry, so each burst **re-rolls its hit zone**. That's the cluster spreading across the target.
|
||
|
||
## So the faithful model is
|
||
|
||
| step | value |
|
||
|---|---|
|
||
| authored `DamageAmount` | the whole salvo (LRM15 = 50) |
|
||
| ctor | `amount /= missileCount` → 3.33; `burstCount = missileCount` |
|
||
| one cluster Missile spawned per trigger | no loop, `missileCount` never read in fire |
|
||
| at impact, Perform re-rolls | `burstCount = min(Random(N) + N/4, N)` — **how many missiles connect**, a quarter to all |
|
||
| handler | applies `amount` **burstCount times**, re-rolling the zone each time |
|
||
|
||
Total delivered = `authored × (hits/N)` — between 25% and 100% of the salvo, spread across zones. That is a genuinely nice model, and it's why the randomization exists.
|
||
|
||
## What that means for the fix
|
||
|
||
**My commit `efc3e9f` is not the faithful path and should be reverted.** Multiplying the lead round by `missileCount` produces roughly the right *average* total but as one lump on one zone, with no spread and no variance — it hard-codes a perfect 100% salvo every time.
|
||
|
||
The faithful path is three changes:
|
||
|
||
1. **Revert the ×N on the lead round** — the per-missile amount was already correct.
|
||
2. **Implement the handler's burst loop** — apply the zone damage `burstCount` times, re-resolving the zone per iteration. This is the binary's own structure, in the one place that makes `burstCount` mean "number of applications."
|
||
3. **Carry the missile's randomized burst** at impact instead of the hardcoded `dmg.burstCount = 1`.
|
||
|
||
That also **fixes #106 for free** — splash already dispatches with `burstCount = bursts`, so the falloff starts working the moment the loop exists. Same for anything else that sets it.
|
||
|
||
## One correction to record
|
||
|
||
The KB's `[T1]` "KEY FACT" in `combat-damage.md` — *"burstCount is cosmetic for zone damage"* — is wrong. The verified half (`TakeDamage` ignores it) was generalised into a conclusion about the system, and that inference then justified task #62's salvo-lead design. It's the same shape as the seek-level mistake: a correct local reading, over-generalised because the consumer lived somewhere I hadn't looked.
|
||
|
||
Want me to revert `efc3e9f` and implement the burst loop? It touches the damage path for every weapon, so I'd bench direct fire and splash alongside missiles before pushing.

yes revert it and implement the burst loop - just verify all the weapons classes are inflicted the proper damage afterward since this tocuhes all of them
|
||
|
||
**[2026-08-01 09:30:32] CLAUDE:**
|
||
|
||
**The burst loop already exists** — mech.cpp:996-1033, task #80, faithfully reconstructed with the per-burst zone re-roll and crit roll. I was wrong that it was missing; I trusted the KB's "cosmetic" claim instead of reading our own handler.
|
||
|
||
So the real defect is much smaller: **the projectile impact hardcodes `dmg.burstCount = 1`**, throwing away the cluster count. Reverting my hack and carrying the authentic randomized burst instead:
|
||
|
||
**[2026-08-01 09:31:40] CLAUDE:**
|
||
|
||
Now the all-weapons verification you asked for — the burst loop touches every damage consumer, so let me measure each class:
|
||
|
||
**[2026-08-01 09:34:24] CLAUDE:**
|
||
|
||
Bursts are all 1 — the cluster roll isn't reaching the handler. Let me check whether missiles fired at all:
|
||
|
||
**[2026-08-01 09:35:17] CLAUDE:**
|
||
|
||
Bursts are still 1, and I can see why: the **message manager rebuilds the damage record** from a stream carrying only `{damageType, damageAmount, subsystemID}` — `DamageInformation` has no `burstCount` field, so it's dropped in transit.
|
||
|
||
And that points at the real divergence. The arcade Missile dispatches **directly** at the victim (`FUN_004be078`: `param_2->Dispatch(&msg)`) — it never goes through the shooter's manager:
|
||
|
||
**[2026-08-01 09:38:37] CLAUDE:**
|
||
|
||
Now it's working correctly:
|
||
|
||
| class | burst | verdict |
|
||
|---|---|---|
|
||
| **EXPLOSIVE** (missile) | `2x4, 4x12, 5x5, 6x12` | cluster spread across **7 zones** — the [n/4..n] roll for n=6 |
|
||
| **ENERGY** (beam) | `1x7` | unchanged — no regression |
|
||
| **type4** | `1x4` | unchanged |
|
||
| **COLLISION** | 0 reached armour | divert intact |
|
||
|
||
Let me confirm explosions are still right, since the manager path is now gone entirely:
|
||
|
||
**[2026-08-01 09:38:57] CLAUDE:**
|
||
|
||
Explosions are right: 10 projectile impacts produce **no** bundled explosion (the 11 `[boom]` are direct-fire), so the double blast is gone architecturally. That makes my `MarkRoundDetonated` suppression dead code — removing it:

Now correcting the KB claim that misled me, since it's still there to mislead the next pass:
|
||
|
||
**[2026-08-01 09:43:01] CLAUDE:**
|
||
|

Line 334-336 repeats it — sweeping that too:
|

||
**[2026-08-01 09:44:38] CLAUDE:**
|

|
||
Reverted and reimplemented faithfully — `3b7c19c`, pushed.
|
||
|
||
## What the binary does
|
||
|
||
| | |
|
||
|---|---|
|
||
| ctor `@004bcff0` | `burstCount = missileCount`; `damageAmount /= missileCount` |
|
||
| fire `@004bcc60` | spawns **one** Missile — no loop; the salvo *is* one cluster round |
|
||
| `Missile::Perform` | rolls how many connect: `Random(n) + n/4`, clamped to `n` |
|
||
| `FUN_004be078` | dispatches **directly** at the victim, not via the manager |
|
||
| handler `@0x4a0439` | applies the hit `burstCount` times, re-rolling the zone each burst |
|
||
|
||
## The actual defect
|
||
|
||
Our handler already had that loop (task #80) — I was wrong that it was missing. The real bug was narrower and nastier: the projectile impact hardcoded `burstCount = 1` **and** routed damage through the `SubsystemMessageManager`, whose consolidation rebuilds the record from a stream of only `{damageType, damageAmount, subsystemID}`. `DamageInformation` has no `burstCount` field, so the cluster count was dropped in transit no matter what the round carried.
|
||
|
||
Fixing it by dispatching directly, as the binary does, also **retires the double explosion architecturally** — the second blast was the manager's bundled explosion, and projectiles no longer touch the manager. The `MarkRoundDetonated` flag I added earlier is dead code and is gone.
|
||
|
||
## All-weapon audit (one run, everything firing)
|
||
|
||
| class | applications | bursts | verdict |
|
||
|---|---|---|---|
|
||
| **Missile** | 38 | `1×2, 2×6, 3×9, 4×4, 5×5, 6×12` over **11 zones** | the `[n/4..n]` roll + per-burst zone re-roll — the cluster scattering |
|
||
| **Energy** | 8 | all 1 | unchanged |
|
||
| **type4** | 8 | all 1 | unchanged |
|
||
| **Collision** | 0 reached armour | — | divert intact |
|
||
|
||
Explosions: 10 projectile impacts, zero bundled blasts; direct-fire still queues its own (11 made).
|
||
|
||
## Two things worth your attention
|
||
|
||
**Cross-pod is not verified.** `Dispatch` reroutes to a replicant on its own and the binary depends on exactly that, but I removed the manager routing, so MP damage delivery wants a two-node run before the next drop. I flagged it on the issue rather than assuming it's fine.
|
||
|
||
**#106 was my own bad issue and is closed.** I claimed splash's falloff was computed then discarded. It never was — splash dispatches directly, so it always reached the burst loop intact. The design question I asked you to arbitrate was a false choice; the engine already honours `burstCount` in exactly one correct place.
|
||
|
||
The underlying lesson is now gotcha **§24**: the KB carried *"burstCount is cosmetic for zone damage"* tagged `[T1]`. The first half was byte-verified; the second was an inference that inherited the tag and then justified task #62's design, quietly dividing every salvo by its missile count for months. Swept both copies. The tell was available the whole time — the binary spends instructions *randomising* `burstCount` at impact, and nobody rolls dice on a decorative value.

run the mp bench to verify cross-pod damage
|

|

**[2026-08-01 10:22:23] CLAUDE:**
|
||
|
||
Good template. Writing a focused two-node cross-pod damage bench:
|
||
|
||
**[2026-08-01 10:27:32] CLAUDE:**
|
||
|
||
Cross-pod delivery is **verified** — and the accounting is exact:
|
||
|
||
| burst | rounds A fired | applications B received | expected |
|
||
|---|---|---|---|
|
||
| 2 | 6 | 12 | 6×2 ✔ |
|
||
| 3 | 6 | 18 | 6×3 ✔ |
|
||
| 4 | 7 | 28 | 7×4 ✔ |
|
||
| 5 | 7 | 35 | 7×5 ✔ |
|
||
| 6 | 7 | 42 | 7×6 ✔ |
|
||
|
||
The cluster count survives the wire intact. But node A took 8 explosive hits totalling `dlvl=8.0` — 1.0 per application, i.e. a zone destroyed each time — while node B fired nothing. Let me check that before calling this clean:
|
||
|
||
**[2026-08-01 10:27:58] CLAUDE:**
|
||
|
||
`amt=630`/`665` on entity `2:23` — that's the *death explosion* splash (B died repeatedly under A's fire), not weapon damage. Let me confirm it predates my change rather than being caused by it:
|
||
|
||
**[2026-08-01 10:28:13] CLAUDE:**
|
||
|
||
Player logs have no `[dmghit]` (gate off), so let me check the context around one of those hits instead:
|
||
|
||
**[2026-08-01 10:28:38] CLAUDE:**
|
||
|
||
Not my change — it's node A's **own ammo bay cooking off**:
|
||
|
||
```
|
||
[ammo] AmmoBinSRM6_1 BAY FIRE DETONATION: 19 rounds x 35 = 665 (type 2)
|
||
ammo explosion damaging dz_ltorso
|
||
[dmghit] mech=2:23 zone=6 vital=1 type=2 amt=665 burst=1 lvl 0->1
|
||
```
|
||
|
||
`[mp-self] MY mech entityID=2:23` — that's A damaging itself. The bay path reads the authored 35 directly, untouched by the launcher's division, so it's independent of this work.
|
||
|
||
**[2026-08-01 10:29:34] CLAUDE:**
|
||
|
||
Cross-pod damage is verified — the caveat on `3b7c19c` is cleared.
|
||
|
||
## Result
|
||
|
||
Two nodes chasing and firing for four minutes. Node A fired, node B received:
|
||
|
||
| burst | rounds A fired | applications B received | expected |
|
||
|---|---|---|---|
|
||
| 2 | 6 | 12 | 12 ✔ |
|
||
| 3 | 6 | 18 | 18 ✔ |
|
||
| 4 | 7 | 28 | 28 ✔ |
|
||
| 5 | 7 | 35 | 35 ✔ |
|
||
| 6 | 7 | 42 | 42 ✔ |
|
||
|
||
Exact in every band — `rounds × burst`, no loss. **135 of B's 142 explosive applications carried burst > 1**, where the old message-manager route flattened every one to 1. Energy stayed at burst 1 on both nodes; neither crashed.
|
||
|
||
So direct `Dispatch` reroutes cross-pod exactly as the binary relies on, and removing the manager routing cost us nothing.
|
||
|
||
## One thing the run turned up
|
||
|
||
Node A appeared to "take" 8 explosive hits of ~665 each while node B fired nothing. That looked alarming, so I chased it — it's A's **own ammo bay cooking off**:
|
||
|
||
```
|
||
[ammo] AmmoBinSRM6_1 BAY FIRE DETONATION: 19 rounds x 35 = 665 (type 2)
|
||
[dmghit] mech=2:23 zone=6 vital=1 type=2 amt=665 burst=1 lvl 0->1
|
||
```
|
||
|
||
Not caused by this work — that path reads the authored resource value, not the launcher's divided member. But it's worth your attention on its own: **#46 was filed for the opposite symptom** ("two bay fires each, no death"), and Lynx reported "Ammo bay fire got me" in the 674 session. So bay fires now kill.
|
||
|
||
Possibly too hard. 665 into a zone that dies at ~63 is roughly 10× overkill, computed as `remaining rounds × authored salvo damage`. That makes every bay fire unconditionally fatal, and a full bin enormously more lethal than a near-empty one with no practical difference since both kill outright. I noted it on #46 rather than acting — it's a live gameplay-balance question, not obviously a bug.
|
||
|
||
Everything from tonight is committed and pushed. The tracker is current: #95 and #84 fixed and verified end-to-end, #106 closed as my own mistaken issue, the `burstCount` KB claim corrected and swept with gotcha §24 recording the over-generalisation trap.

**[2026-08-01 14:49:47] CLAUDE:**
|
||
|
||
Lynx ran `.674` throughout, and the shape is telling — many 5–8 line sessions that died instantly, then three real gameplay runs. Let me look at both:
|
||
|
||
**[2026-08-01 14:49:59] CLAUDE:**
|
||
|
||
Confirmed **#68** precisely — `[lobby] join: no btl4 lobby found` then silent exit, and he hit it repeatedly. Let me quantify and compare his install to the others:
|
||
|
||
**[2026-08-01 14:50:12] CLAUDE:**
|
||
|
||
8 silent lobby exits — solid evidence for #68. (`environ.ini: 0` is common across players, not a Lynx anomaly.)
|
||
|
||
Now his headline find, the Owens hang. Let me look for the gait stall around a throttle reversal:
|
||
|
||
### [2026-08-01 14:51:55] USER
|
||
|
||
just a point, he is old and none of the other players had issues so it is quite possibly user error but go ahead and check. also he said later that the owens hang wasnt actually a crash. i think at bets we need a detent between forward and reverse maybe. i think he just found a inbetween spot that causes an audio loop or something. i dont think anything actually crashed since he said the program "recovered"
|
||
|
||
**[2026-08-01 14:52:11] CLAUDE:**
|
||
|
||
Fair — and that reframing matters. Let me check the audio angle, because something concrete showed up:
|
||
|
||
**[2026-08-01 14:52:31] CLAUDE:**
|
||
|
||
That's the real finding, and it's **universal — every player, every session**:
|
||
|
||
| player | ACQUIRE FAILED lines | live sources |
|
||
|---|---|---|
|
||
| Lynx | 4,657 | 256 (cap) |
|
||
| ConnMan | 6,571 | 256 |
|
||
| Rajel | 6,275 | 256 |
|
||
| Sauron | 5,245 | 256 |
|
||
| Oracle | 3,031 | 256 |
|
||
|
||
`live=256` pinned at the cap and never dropping is a leak, not contention. Let me see how fast it fills and whether it ever recovers:
|
||
|
||
**[2026-08-01 14:52:52] CLAUDE:**
|
||
|
||
The pool exhausts **9.3% into the session and never recovers** — still failing at 96.8%. Let me get the census:
|
||
|
||
**[2026-08-01 14:53:03] CLAUDE:**
|
||
|
||
The census contradicts the failure message — `live=6` in the census while ACQUIRE FAILED reports `live=256`. Let me see what those two counters actually are:
|
||
|
||
**[2026-08-01 14:53:34] CLAUDE:**
|
||
|
||
Now I understand both counters — same global, sampled at different times. Sources spike to OpenAL's 256 hard limit during combat bursts, `alGenSources` fails, then they drain back to ~6 by the next 30s census. It's allocation churn, not a steady leak.
|
||
|
||
**[2026-08-01 14:54:32] CLAUDE:**
|
||
|
||
You're right on both counts, and the log backs you up.
|
||
|
||
## The Owens "hang"
|
||
|
||
Not a crash — nothing in his log shows one, and he said it recovered. I've downgraded #102 and reframed it as you described: an in-between throttle position at the forward/reverse boundary that leaves the gait state machine without a clean transition, so the animation parks mid-stride until any torso input re-drives it. **A detent at that boundary is probably the whole fix**, same as the one already added for walk→run. I also noted explicitly that no other player reported it and he was the only one on keyboard, so it should be weighted as a low-severity edge case.
|
||
|
||
## The lobby thing — also likely user error, but the issue is still valid
|
||
|
||
He hit it 8 times: `[lobby] join: no btl4 lobby found`, then the process exits. Every lookup was *correct* — he was joining before anyone hosted, and initially running `join.bat` (the dev-console one) instead of `play_steam.bat`.
|
||
|
||
So the lobby code isn't broken. What's broken is that the game **knows** why it quit, writes the reason to the log, and then dumps silently — leaving him unable to tell a mis-click from a broken build. That's #68, and it's a small UX fix. The `.bat` naming is worth a glance too.
|
||
|
||
## What his log actually turned up
|
||
|
||
Chasing his audio complaint found something universal that outranks anything Lynx-specific:
|
||
|
||
| player | ACQUIRE FAILED | live at failure |
|
||
|---|---|---|
|
||
| Conn Man | 6,571 | 256 |
|
||
| Rajel | 6,275 | 256 |
|
||
| Sauron | 5,245 | 256 |
|
||
| Lynx | 4,657 | 256 |
|
||
| Oracle | 3,031 | 256 |
|
||
|
||
**Every player, every session.** In Lynx's largest session it starts 9.3% in and never stops.
|
||
|
||
The two counters looked contradictory (failures say `live=256`, the census says `live=6`) — same global, different moments. Sources spike to **256, OpenAL's hard per-context limit**, during combat bursts, then drain back by the next census. So it's **allocation churn, not a leak**: `AcquireSources` generates sources on demand instead of recycling a preallocated pool. That changes the fix from "hunt a leak" to "pre-allocate and reuse."
|
||
|
||
Worth re-testing together afterward rather than debugging separately: **#99** (no coolant alarm — an alarm that can't acquire a source is silent, which fits Oracle's "was sounding, resolved a leak, but there was another" as well as edge-triggering does), **#5** (buzz sustains), **#51** (flush loops forever), and the audio half of Lynx's Owens report.
|
||
|
||
That's all five logs processed. The most valuable thing in Lynx's, ironically, wasn't the bug he was chasing — it was the confirmation that the audio pool problem is affecting everyone, all the time.

|

**[2026-08-01 14:55:42] CLAUDE:**
|
||
|
||
Good question — and it changes how I'd read several open issues. Let me check one thing first, because it makes the answer concrete rather than speculative:
|
||
|
||
**[2026-08-01 15:02:14] CLAUDE:**
|
||
|
||
API Error: Response stalled mid-stream. The response above may be incomplete.
|
||
|
||
### [2026-08-01 15:02:24] USER
|
||
|
||
you can proceed
|
||
|
||
**[2026-08-01 15:03:39] CLAUDE:**
|
||
|
||
First, a correction I owe you: I suggested the missing coolant alarm and missile warning might be *downstream* of this. They aren't — there's no alarm implementation in the code to starve. Those features are genuinely unbuilt. I floated that without checking, which is the same over-generalisation I'd filed as a gotcha a day earlier; I've corrected it on the issue rather than quietly dropping it.
|
||
|
||
## What a player actually experiences
|
||
|
||
**Sounds that just don't happen** — and specifically, missing *most* during heavy fighting, because that's when the burst blows through the 256-source cap. The moments where audio carries information are exactly the moments it fails.
|
||
|
||
**Sounds that won't stop.** The failure is on *acquire*, so anything that already holds a source keeps playing. A loop that got in early runs forever while everything after it goes silent. That's the flush-loop and buzz-sustain family.
|
||
|
||
**It degrades as the match goes on.** Starts about 10% in, never recovers. Early game sounds fine; by mid-match it's threadbare.
|
||
|
||
**It's inconsistent for the same action.** Fire the same weapon twice, hear it once. That's the worst property — it makes the bug feel unreproducible.
|
||
|
||
## How they'd report it — and why that's the real problem
|
||
|
||
Not as "the audio system is failing." They'd report it as **a scatter of unrelated broken features**: *my PPC has no sound*, *the flush noise is stuck*, *combat feels dead late in the match*, *something's off*. Or they'd blame their own headset and say nothing at all. Lynx's "Vulture audio bug" — which he never got around to describing — is very plausibly exactly this, and he framed it as a Vulture problem.
|
||
|
||
Two practical hazards for us:
|
||
|
||
**Verification.** Any fix whose acceptance test is *"did you hear it?"* can't be confirmed by players right now. If we build the coolant alarm and they still hear nothing, we'd read that as the fix failing. That directly corrupts the loop we've been relying on to close issues — and we've been closing a lot of them on player confirmation.
|
||
|
||
**Wasted work.** The inverse risk: someone reimplements a feature that exists but is inaudible. Not currently the case for the alarms (they're genuinely missing), but it's the trap this class of bug sets.
|
||
|
||
## What I'd take from it
|
||
|
||
The fix itself looks tractable — `AcquireSources` generates sources on demand instead of recycling a preallocated set, so it's a pooling change rather than a leak hunt. Given it affects every player in every session and blocks verification of anything audio-shaped, I'd rank it above the remaining coolant polish for the next build.
|
||
|
||
Worth telling the testers plainly, too: *audio is known-broken mid-match; don't file individual sounds, and don't treat silence as evidence a fix didn't land.* That stops you collecting a pile of duplicate reports pointing at one root cause.

||

fix the audio source pooling
|
||
|
||
**[2026-08-01 15:07:29] CLAUDE:**
|
||
|
||
Now I have the full picture: acquire calls `alGenSources`, release calls `alDeleteSources` — create/destroy per sound event. Let me check the set structure and capacity:
|
||
|
||
**[2026-08-01 15:07:55] CLAUDE:**
|
||
|
||
Everything I need. Let me check whether sources use buffer queueing, since that affects safe recycling:
|
||
|
||
**[2026-08-01 15:08:09] CLAUDE:**
|
||
|
||
No buffer queueing — static attach only. But `AL_LOOPING` **is** set per-source, which is exactly what a recycled source must not inherit. Implementing the pool:
|
||
|
||
**[2026-08-01 15:08:33] CLAUDE:**

||
Now the pool itself and the release side:
|
||
|
||
**[2026-08-01 15:09:17] CLAUDE:**
|
||
|
||
Need forward declarations, since the pool is defined after its use site — and the census should report pool health now:

**[2026-08-01 15:13:53] CLAUDE:**

Let me get a same-bench "before" so the comparison is clean rather than field-vs-bench:
|
||
|
||
**[2026-08-01 15:18:22] CLAUDE:**
|
||
|
||
The bench doesn't reproduce the failure — **pre-fix also shows 0**, peaking at only 49 live sources. Solo combat isn't dense enough to reach the 256 cap. Let me restore the fix and test under multi-node conditions, which is what the field logs actually represent:

Two nodes: **0 failures**, ~7,000 reuses each. But note the high-water mark: 138 solo → 149 with two nodes, against a 200 cap. That scales with player count, so let me not leave it guessable:
|
||
|
||
**[2026-08-01 15:24:52] CLAUDE:**
|
||
|
||
Stale process holding the exe — killing and rebuilding:
|
||
|
||
**[2026-08-01 15:29:43] CLAUDE:**
|
||
|
||
Fixed and pushed (`ad9dfad`).
|
||
|
||
## Cause
|
||
|
||
`RequestAudioChannels` called `alGenSources()` per sound event; `ReleaseSourceSet` called `alDeleteSources()` on release. Create and destroy, per sound. OpenAL sources are a scarce driver resource capped at 256 per context, and a combat burst churned straight through it.
|
||
|
||
The two contradictory counters were the tell — `ACQUIRE FAILED` always printing `live=256` while the census printed `live=6` is the same global sampled at different moments. Spike, fail, drain. Churn, not a leak.
|
||
|
||
## Fix
|
||
|
||
Sources are generated once up to a cap and recycled through a free list. Release scrubs and parks instead of deleting, so steady-state play allocates nothing.
|
||
|
||
**The scrub is the load-bearing part**, not hygiene. A recycled source inherits whatever the last owner set, and the engine sets `AL_LOOPING` per sound. Hand a looping source to a one-shot and it plays forever — pooling *without* the scrub would have manufactured the exact "stuck looping" bug we already have open as #51 and #5.
|
||
|
||
## Verification, and its limit
|
||
|
||
| bench | result |
|
||
|---|---|
|
||
| solo, sustained fire | 0 failures, pooled 152, **21,998 reuses** |
|
||
| two nodes, 4 min | 0 failures both, ~7,000 reuses each |
|
||
|
||
But I have to be straight about what that does and doesn't show: **the bench doesn't reproduce the original failure.** I stashed the fix and ran the pre-fix binary through the same bench — it also scored 0, peaking at only 49 live sources. Solo and two-node combat simply isn't dense enough to reach 256.
|
||
|
||
So this proves the pool works and eliminates the allocation churn. It does **not** prove the field failures are gone. The five player logs remain the only real "before", and the next playtest is the actual test.
|
||
|
||
## One thing to watch
|
||
|
||
Peak demand is set by how many audio *components* are alive — each reserves a SourceSet of up to 25 voices and holds them — not by audible sounds. Measured high-water was 138 solo, 149 two-node. That scales with player count, so five players could approach the ceiling.
|
||
|
||
Rather than guess, I set the cap near the driver limit (240) and added a high-water line that fires once per 25-source band:
|
||
|
||
```
|
||
[audio] source pool high-water: 150 of 240
|
||
```
|
||
|
||
If next session's logs show that climbing past ~200, the remaining work is *retention* — reclaiming sources from finished one-shots instead of holding them to entity teardown — not a bigger pool. That's a real possibility, and now we'll have data instead of speculation.
|
||
|
||
Worth telling testers: re-check #51, #5, and the looping audio in #102 *after* this, since they may simply vanish.

i think in chat rajel mentioned this error.. something about failure to aquire showing up in the logs a lot or something. is this the same error she mentioned? i think she was looking at loggs
|
||
|
||
**[2026-08-01 15:31:46] CLAUDE:**
|
||
|
||
Let me check rather than guess — I don't see it in tonight's transcript, but this diagnostic predates tonight:
|
||
|
||
**[2026-08-01 15:32:00] CLAUDE:**
|
||
|
||
That's a significant find — the code already contains a *prior* analysis of this exact error, and a prior fix attempt. Let me read it:
|
||
|
||
**[2026-08-01 15:32:54] CLAUDE:**
|
||
|
||
Important find, and it changes my confidence. Let me check the frame-time angle the prior note explicitly asks for:
|
||
|
||
**[2026-08-01 15:33:10] CLAUDE:**
|
||
|
||
`[rstat] frames=N avg=Xms` — that's what I need. The prior note says explicitly to measure frame time, and I didn't. Doing that now as an A/B:
|
||
|
||
**[2026-08-01 15:41:01] CLAUDE:**
|
||
|
||
Post-fix **7.79 ms** vs pre-fix **8.67 ms** over ~10k frames each — pooling is a net frame-time *win*, not a cost. Restoring the fix:
|
||
|
||
**[2026-08-01 15:42:48] CLAUDE:**
|
||
|
||
Almost certainly the same error — and your memory of it prompted a find I should have made myself.
|
||
|
||
## Is it the same one?
|
||
|
||
Yes, same string: `[audio] ACQUIRE FAILED (requested=4 live=256 fails=N) -- the pool is exhausted; expect dropouts`. It **predates tonight** — it's all over the night-5 logs (Conn Man's: 235 lines in one, 1,000 in another, from 27 July).
|
||
|
||
I can't confirm it was Rajel specifically. It isn't in tonight's transcript you pasted, and the night-5 logs I have are Conn Man's. So either she mentioned it in an earlier session, or she was reading a log and spotted it — which would be a sharp catch either way, since it's a diagnostic line, not something the game surfaces.
|
||
|
||
## The part that matters more
|
||
|
||
Chasing your question, I found that **the code already contained a prior analysis of this exact error, which deliberately decided not to act on it** — and I didn't read it before implementing. It concluded the 23 July atomic-delete fix had settled things with *"no field complaints since"*, that the remaining exhaustion was transient and likely sub-perceptual, and that the 256 ceiling was usefully acting as a CPU governor. There's even an opt-in `BT_AUDIO_SOURCES` gate left behind for it.
|
||
|
||
Two things follow.
|
||
|
||
**That "no field complaints since" claim was wrong**, and it was still sitting there to mislead the next reader. All five 4.11.674 logs are saturated. I've corrected it in place rather than leaving my fix to silently contradict it.
|
||
|
||
**But the prior reasoning doesn't invalidate the fix** — it was about raising the source *budget*, which multiplies mixing cost. Pooling changes no budget: idle pooled sources are stopped and detached, so they cost nothing to mix. Different lever.
|
||
|
||
The note explicitly says to measure frame time if anyone touches this, so I did — same bench, both ways:
|
||
|
||
| | frames | weighted avg |
|
||
|---|---|---|
|
||
| pre-fix | 9,390 | **8.672 ms** |
|
||
| post-fix | 10,047 | **7.794 ms** |
|
||
|
||
Removing ~20k `alGenSources`/`alDeleteSources` driver calls per match is a net **win**, not a cost — about 10%, pointing the opposite way from the concern. Single run each, so indicative rather than definitive.
|
||
|
||
`BT_AUDIO_SOURCES` stays opt-in and unset; that part of the old reasoning still stands on its own.
|
||
|
||
The lesson for me is the same shape as the `burstCount` one, twice in two days: there was a written record right next to the code I was changing, and I went straight to the symptom without reading it. Worth me checking the surrounding comments before implementing, not after.
|
||

ok lets try to fix some of their game play bugs.. lets focus on the bugs that make the overall experience more fun. so i think from last night a common complain was that coolant leaking systems werent always flashing alarms. did you see that error? it seems like not all conditions are reliably turning on the flashing panel buttons.
|
||
|
||
**[2026-08-01 15:45:04] CLAUDE:**
|
||
|
||
Let me find how the leak reaches the panel lamp.
|
||
|
||
**[2026-08-01 15:46:45] CLAUDE:**
|
||
|
||
`btl4galm.cpp` — the alarm gauge. Let me look at what drives its flash:
|
||
|
||
**[2026-08-01 15:48:36] CLAUDE:**
|
||
|
||
The alarm→lamp mapping is solid. The question is who *activates* it. Let me find the trigger:
|
||
|
||
**[2026-08-01 15:49:27] CLAUDE:**
|
||
|
||
`BT_LAMP_LOG` gives me a diagnostic. Now who calls `ReportStatusSet` with CoolantLeaking?
|
||
|
||
**[2026-08-01 15:50:05] CLAUDE:**
|
||
|
||
The trigger is `sub->GetStatusFlags()` — bit 2 = CoolantLeaking. Let me see who provides it:
|
||
|
||
**[2026-08-01 15:50:34] CLAUDE:**
|
||
|
||
`HeatSink::GetStatusFlags` raises the leak bit only when `coolantActive && HeatModelActive()`. That second gate is suspicious — let me see what it depends on:
|
||
|
||
**[2026-08-01 15:51:19] CLAUDE:**
|
||
|
||
`HeatModelActive` is a stable per-player expert flag, so not the intermittency. That leaves `coolantActive`. Let me read how it's set:
|
||
|
||
**[2026-08-01 15:51:49] CLAUDE:**
|
||
|
||
Found the mechanism — and it's load-dependent:
|
||
|
||
```cpp
|
||
coolantDraw = zoneDamage * heatLoad; // leak scales with HEAT LOAD
|
||
if (!coolantActive && coolantDraw > 0.003) coolantActive = 1; // lamp on
|
||
else if (coolantActive && coolantDraw < 0.0025) coolantActive = 0; // lamp OFF
|
||
```
|
||
|
||
So a damaged sink stops "leaking" whenever heat load drops — the lamp goes out even though the damage is still there. That's exactly "not always flashing." The hysteresis itself is authentic (both constants are in the binary), so the question is whether `heatLoad` is faithful:
|
||
|
||
**[2026-08-01 15:53:00] CLAUDE:**
|
||
|
||
`radiatedHeat = currentTemperature * coolantLevel` — so the leak is self-damping. But re-reading Oracle's words, he knew he *was* leaking and the **button** didn't light — that points at lamp resolution, not leak detection. Let me check the resolve path:
|
||
|
||
**[2026-08-01 15:53:19] CLAUDE:**
|
||
|
||
There's already a `[galarm]` diagnostic — but the `lamp_id < 0` path (lamp never *resolved*) returns silently, which is the blind spot. Let me light that up and measure rather than guess:
|
||
|
||
**[2026-08-01 15:54:19] CLAUDE:**
|
||
|
||
The `\n` escape got mangled. Fixing the line directly:
|
||
|
||
**[2026-08-01 15:54:49] CLAUDE:**
|
||
|
||
Let me use `std::endl` and avoid the escape entirely:
|
||
|
||
**[2026-08-01 15:59:11] CLAUDE:**
|
||
|
||
Only **Myomers** leaked, and its lamp *did* resolve and flash — then CLEARED. So the mapping works; the state doesn't hold. Let me see why it cleared:
|
||
|
||
**[2026-08-01 15:59:26] CLAUDE:**
|
||
|
||
`draw=0.1065` — 35× above the 0.003 threshold, and coolant stays topped up. So `coolantActive` never dropped. Something *else* cleared the status. Let me look at the CLEAR in context:
|
||
|
||
**[2026-08-01 16:00:01] CLAUDE:**
|
||
|
||
The clear came from **respawn** — legitimate. So Myomers works end-to-end. That means the failing cases are other subsystem classes. Lynx's "**Sensors** show a fail, I have a leak warning but no indicators" is the clue. Let me target a zone hosting a condenser instead:
|
||
|
||
**[2026-08-01 16:02:54] CLAUDE:**
|
||
|
||
**Reproduced it.** Condenser6 leaks, alarm fires, and *both* authored lamp codes fail to resolve — nothing flashes:
|
||
|
||
**[2026-08-01 16:03:15] CLAUDE:**
|
||
|
||
The table is the bug. Note it's documented as **1-based** but bounds-checked as 0-based — and compare it against the fixed loop map:
|
||
|
||
```
|
||
kFixed[6] = { 0x2F, 0x2E, 0x2D, 0x2C, 0x2B, 0x2A }; // six cooling loops
|
||
kBTCondenserLamp[6] = { 0x7, 0x2F, 0x2E, 0x2D, 0x2B, 0x2A }; // 0x2C is MISSING
|
||
```
|
||
|
||
Let me confirm the real table from the binary rather than infer it:
|
||
|
||
**[2026-08-01 16:03:31] CLAUDE:**
|
||
|
||
Those decode as ASCII, not integers — so the cited addresses hold strings. Let me look:
|
||
|
||
**[2026-08-01 16:03:57] CLAUDE:**
|
||
|
||
The cited addresses hold gauge-type strings, so the table provenance is questionable. Let me find the real table by its byte pattern:
|
||
|
||
**[2026-08-01 16:04:49] CLAUDE:**
|
||
|
||
No byte match — so these tables are unverified reconstruction, and the cited provenance addresses don't hold them. Let me check the numbering convention before fixing:
|
||
|
||
**[2026-08-01 16:05:22] CLAUDE:**
|
||
|
||
Let me get the actual runtime value rather than assume the convention:
|
||
|
||
**[2026-08-01 16:08:44] CLAUDE:**
|
||
|
||
Confirmed — `condenserNumber=6`, **1-based**, matching the name. So with the `n < 6` guard:
|
||
|
||
| condenser | gets | should be |
|
||
|---|---|---|
|
||
| 1–3 | 0x2F, 0x2E, 0x2D | correct |
|
||
| 4 | 0x2B | **0x2C** — flashes loop 5's button |
|
||
| 5 | 0x2A | **0x2B** — wrong button |
|
||
| 6 | *rejected* | **0x2A** — nothing at all |
|
||
|
||
And condenser *N* drives cooling-loop *N*, whose six lamps are already in the verified `kFixed` map. Let me fix it by reusing that instead of a duplicate table:
|
||
|
||
**[2026-08-01 16:12:07] CLAUDE:**
|
||
|
||
**Fixed** — Condenser6 now resolves to lamp `0x2a` and flashes, the sixth cooling-loop button.
|
||
|
||
The run also surfaced a *separate* gap now that the silent path logs: a **destroyed HeatSink** (condition 0) resolves no lamp at all. Different condition, so I'll report rather than widen scope.
|
||
|
||
**[2026-08-01 16:13:36] CLAUDE:**
|
||
|
||
Found and fixed it — and it was never intermittent. It's **per-condenser**, and three of the six were wrong.
|
||
|
||
## What was happening
|
||
|
||
`condenserNumber` is **1-based** (verified live: `Condenser6` reports 6), which the lamp table's own comment said. But the bounds check was `n >= 0 && n < 6` — a 0-based bound — and the table it indexed was missing `0x2C`:
|
||
|
||
| condenser | lit | correct? |
|
||
|---|---|---|
|
||
| 1, 2, 3 | 0x2F, 0x2E, 0x2D | ✅ |
|
||
| 4 | 0x2B | ❌ flashes **loop 5's** button |
|
||
| 5 | 0x2A | ❌ flashes **loop 6's** button |
|
||
| 6 | *rejected* | ❌ **nothing at all** |
|
||
|
||
So a leak in loop 6 annunciated nowhere, loops 4–5 lit a neighbour's button, and loops 1–3 were fine. From the cockpit that reads as "sometimes" — and it explains why three players described it three different ways. Oracle's *"aren't always flashing"*, Lynx's *"leaks but no indicators"*, and Sauron's *"indicators sometimes"* are one defect seen from different loops.
|
||
|
||
Condenser N drives cooling-loop N, and those six lamps already exist in the *verified* `coolingLoop1..6` map — so I routed condensers through that and retired the duplicate table rather than patching it.
|
||
|
||
**Verified:** `NO LAMP RESOLVED` → `lamp 0x2a FLASH`.
|
||
|
||
## How I found it
|
||
|
||
The resolve path had a silent `return` when no lamp matched — the exact failure players were hitting produced *zero* log output. I lit that path up first, then damaged a specific zone to force a condenser leak. It named the culprit immediately.
|
||
|
||
That diagnostic is worth keeping; it also caught a **second gap** on the same run, which I filed as **#107** rather than widening scope: a destroyed HeatSink resolves no lamp either, because it isn't a Condenser, Generator, or aux-screen PoweredSubsystem. That one needs an authored-intent answer before inventing a mapping.
|
||
|
||
## One caveat worth stating
|
||
|
||
The retired table cited `@0051d058` as byte-verified. That address holds gauge-type *name strings*, and searching the image for the six loop ids as consecutive int32 finds nothing — so **neither the old table nor my new mapping is byte-grounded**. The correction rests on three checkable things: the 1-based numbering (live), the guard contradicting its own documented indexing, and six condensers mapping onto six loop lamps from the verified map. Tagged T2 — behaviour verified, not byte-verified.
|
||
|
||
Worth asking Oracle to specifically damage a loop-4 and a loop-6 condenser next session and confirm the button that flashes is the one actually leaking.
