Joe DiPrimaandClaude Fable 5 9c83a468db #82 ROOT FIX: reconstruct the crash SELF-DAMAGE -- wall-grinding now hurts,
the knockdown storm self-limits, peers keep the limp

The 'peers see a limping mech skating' report decomposed into a wall-grind
KNOCKDOWN STORM: a gimped mech held against a blocking solid re-crashes each
time its gg cycle rebuilds speed (the gg ceiling is authentically the clip's
natural speed -- bhk1 ~14.9 u/s, ceiling+divisor @0x544/0x548, loader formula
byte-matched -- so iv2 ~222 >> the 40.0 threshold @0x4ab184), and every
type-5 KNOCKDOWN broadcast floors all peers' replicants into knockdown/trn
churn: gliding + leg-lifts = skating.  Turning and crushable cars were
A/B-exonerated (grass circling: 198 replicant gimp entries, 17 crunches,
zero broadcasts).

What the binary has that the port lacked -- recovered from the EXPORT GAP by
raw disasm (scratchpad/night6/gap_4a9770.txt, @4aa89f-4aaab4) -- is the crash
branch's tail: fallDirection = worldToLocal(damageForce) (FUN_0040879c, M^T v,
un-normalized), fallScalar = -(fallDirection . localVelocity.linearMotion),
and a self-dispatched TakeDamageMessage{0x64, zone=-1, the engine-computed
collision Damage verbatim}.  A wall crash COSTS ARMOR, so the grind degrades
the mech instead of looping forever.  That dispatch was the long-standing
'DEFERRED' note in the response policy; now reconstructed.

Falsified en route (comments + KB corrected, do not revive): the stagger's
FUN_004a4c54(1)/(0x20) 'action-request flags' feed NO drive suppressor --
image-wide sweep + full gap disasm show word[this+0x18] is read only by the
net record emitter; the bmp clip applies NO root motion (adv=0 measured); the
'gimp cap 5.8' figure was the BACK-cycle stride printed under a misleading
label (now ggCapL/R; @0x52c has no binary consumer).

Verified (mp_gimpAB rigs): arena1 wall-grind now 4 bounded strikes, limper
dies of its crashes and respawns cleanly twice (START->RESET, no strand);
grass circling unchanged-clean (198 replicant gimp states, 0 knocks).
Rig: pid capture race fixed (a missed winpid left a stale node holding the
-net port -> null runs), per-config sweep added.

Joe DiPrimaandClaude Fable 5 4e89baeff3 bench parity: local nodes now launch exactly like a player's shortcut
Local benches had drifted from the shipped launchers and every divergence
cost a debugging session:

  * no BT_START_INSIDE -> benches opened in the EXTERNAL CHASE camera while
    every player starts in the COCKPIT.  The first first-person look at a
    bench window was misread as a broken HUD.
  * novice bench eggs  -> every SHIPPED egg is expert; novice gates off the
    entire heat model, crits and jams, so bench combat was not field combat.
    (Verified: the aligned node now boots experience=3 simLive=1
    heatModelOn=1, where it used to boot 0/0/0.)
  * 1-LP affinity pins -> starved the gauge executive and produced a false
    "the comms panel never counts deaths" reading.  Two LPs per node keeps
    the documented single-box jitter fix without the starvation.

scratchpad/night6/bench_common.sh now owns the contract (bt_player_env,
bt_launch, bt_expert_egg, bt_novice_egg) copied verbatim from play_solo.bat,
with bt_assert_player_env warning if the shipped bat ever drifts.  All three
4-node benches source it.  The limp bench keeps a novice egg -- expert crits
the aimed leg and the mech turns-but-never-moves -- and now says so loudly.

Also: BT_SHOT_EVERY=<n> headless backbuffer capture (btl4vid.cpp), the tool
this was diagnosed with.  It must sit above the warp phase-0 early-out since
that fn is the per-frame alpha-pass hook.  OS screen-capture is off-limits:
a foreground-lock failure photographed the user's browser instead of the game.

KB: build-and-run.md gains the bench-parity rule + the capture diag;
cockpit-view.md gains the measured aspect/FOV finding (the surround's 2.05:1
view collapses vertical FOV to 31.5 deg vs the pod's 46.8, so fixed canopy
geometry covers 68.6% of the lower half -- NOT a regression: the shipped 643
binary reports identical geometry).
