Joe DiPrimaandClaude Opus 5 8c612e4e18 #137 SOLVED (mechanism): not a respawn bug -- the myomer heat RATE under load is
Controlled A/B on the same bench, only the load differs:

  0.95 throttle + continuous missile autofire : 4 respawns, 17 frozen samples,
                                                T climbs 77 -> ~11,600
  0.50 throttle, no weapons                   : 2 respawns, ZERO post-reset
                                                freezes; T stays ~77

So the respawn is exonerated on measurement, not on argument:
  * the reset works -- T == startingTemperature at every reset, both runs;
  * the stale Myomers::speedEffect (@0x31C, which no RTIS writes) is real but
    self-heals on the next tick (T=77.13 -> speedEffect=1);
  * with ordinary load the myomers never approach failT=2000 after a respawn.

WHAT PLAYERS ARE ACTUALLY SEEING.  Overheat while running hard -> myomers pass
failT=2000 -> derating curve @004b8ac0 returns 0.0 -> chain MAX 0 ->
speedDemand *= 0 -> bogged down -> die (often BECAUSE bogged down).  Respawn
correctly resets to 77.  Resume high throttle + firing and it climbs back over
the cliff within seconds, which reads as "respawned with the heat bar maxed".
That is why it looks like a reset bug and why it is intermittent (~8% of
respawns in the field): it tracks how hard you were driving, not the respawn.

THE REMAINING DEFECT is the CLIMB RATE, not the reset.  Blowing ~6x past a
cliff the design treats as coolant-managed (degradeT=1000 governor onset,
failT=2000) is not a lever a player can work with.  Suspect under review: the
kinetic term.  The binary (@004b8d18) applies NO time_slice to it --
`fVar5 * fVar1` -- while the climb and accel terms both carry param_2, i.e. it
is a per-frame energy add at the pod's fixed ~28 Hz.  Our port rate-normalises
it (`work * (time_slice * 28)`), which agrees per-second at any frame rate, so
that is NOT yet a proven discrepancy -- it needs a term-by-term dump against
the authored tuning (VelocityEfficiency 0.995, AccelerationEfficiency 0.8,
thermalMass 2.5e5, myomers linked Condenser5 = Oracle's "loop 5").

Joe DiPrimaandClaude Opus 5 5556329807 #137: REPRODUCE the myomer freeze -- reset is innocent, the myomers RUN AWAY after it
First reproduction of #137 in a bench.  The reset path is exonerated and the
real defect is located, though not yet explained.

DECOMP RE-READ (what the reset actually does):
  Mech::Reset @0049fb74 walks the roster from index 2 calling vtable +0x28
    (slot 10 = ResetToInitialState), then @0049f788.
  Myomers::RTIS @004b8aa4 -> PoweredSubsystem::RTIS @004b0e6c -> ALWAYS
    HeatSink::RTIS @004ad760, whose first act is
        param_1[0x45] = param_1[0x4f]     // currentTemperature = startingTemperature
    (byte 0x114 = 0x13C).  Our port matches AND additionally resets heatEnergy,
    which it must, since HeatSinkSimulation derives
        currentTemperature = heatEnergy / thermalMass.
  The freeze itself is the derating curve @004b8ac0:
        temp >= degradation(@0x118) -> falls off
        temp >= FAILURE(@0x11C)     -> 0.0  -> chain MAX 0 -> speedDemand *= 0.
  Nothing in the reset chain touches Myomers::speedEffect (@0x31C).

MEASURED (scratchpad/night14/myofreeze.sh -- hot mech, repeated self-kill):

    at-reset   Myomers T=77      deg=1000 fail=2000  speedEffect=0   <- stale
    post-reset Myomers T=77.14                        speedEffect=1   <- 1 frame
    post-reset Myomers T=9297.8  fail=2000            speedEffect=0
    post-reset Myomers T=11620.4 fail=2000            speedEffect=0

So, in order:
  * THE RESET WORKS.  T is exactly startingTemperature at the reset.  My
    original bench was right about that much; it just stopped looking there.
  * THE STALE speedEffect IS REAL BUT HARMLESS -- it survives the reset (no
    RTIS writes it) yet self-heals on the very next tick.  Not the bug.
  * THE MYOMERS THEN RUN AWAY: 77 -> ~11,600 against a FAILURE point of 2,000,
    nearly 6x over, in seconds.  That is not heat earned by running; that is a
    runaway, and it is what pins speedDemand at 0 until it cools -- exactly
    Oracle's "maxed heat bar ... unable to move until it cools off".
  * Rate: 7 of 105 census samples over the failure temp (~6.7%), against the
    field's 5-of-61 respawns (~8%).  Same order, so the bench is reproducing
    the field condition and not a bench artifact.
  * The myomers link to Condenser5 (mass=250000 k=190000) -- literally Oracle's
    "loop 5 and generator D heating up as all the excess heat goes into the loop".

NOT YET ESTABLISHED, and the reason this is a checkpoint and not a fix: whether
the runaway is CAUSED by the respawn or is a heat-model calibration problem that
merely CORRELATES with it (you die when you overheat, so respawns cluster around
hot periods).  The bench drives at 95% throttle with continuous missile autofire,
which is abusive, and the [heat-t] census has no pre-first-reset samples to
compare against.  Next step is to instrument the heat INPUT and diff a
respawn-adjacent window against a steady-running window.

Probe added: [myofreeze] prints T / degradation / FAILURE / speedEffect per
myomers plus the chain MAX the mover multiplies by, AT the reset and for ~4 s
after (armed by Mech::Reset, sampled where the multiplier is formed).  The
post-reset window is what nothing was watching -- sampling only at the reset is
what made this look innocent and got the ticket wrongly closed.

Joe DiPrimaandClaude Opus 5 92783b9935 night14: tracker housekeeping for the 4.11.857 playtest
Closed 5 confirmed-fixed (#52 #108 #140 #141 #142), commented 3 (#135 #146
#147), REOPENED #137, filed #149-#158.

#137 reopened because I closed it wrongly.  Field scan of all four logs: 5 of
61 respawns froze (throttle up, speedDemand pinned at 0) across THREE machines
-- ~8%, which is why a bench that reset cleanly every time never saw it.  The
myomers come up Overheating in the same breath as Mech::Reset, before any
running could earn the heat.  Oracle's 'unable to move' was the detail that
disproved my 'it earns the heat by respawning under throttle' explanation.
