Joe DiPrimaandClaude Opus 5 a4bfb64ace scoring: BIND the scenario role -- one commented-out line zeroed the whole chart
BTPlayer::scenarioRole was never assigned.  The lookup sat commented out with
"the BT role registry (BTMission::GetRoleRegistry()->Lookup) has no WinTesla
analog, so the scenarioRole set by the base Player ctor stands" -- and the base
ctor sets it to NULL (PLAYER.cpp:680).  So it stood NULL forever.

Every scoring value the game has hangs off that pointer, and the shipped
content authors them correctly.  New ungated receipt in the ScenarioRole ctor
prints what a real mission loads:

  [role] 'Role::Default' model='dfltrole' killBonus=500 deathPenalty=500
         dmgInf=1 dmgRcv=0 bias=1 ff=1 return=1000

That IS the original manual's scoring chart -- +500 a kill, -500 a special-case
death, +1 per damage point.  With the pointer NULL every award multiplied
against zero: kills scored the damage tally alone (4.88), the eject charge read
0 (the field log's "PUNCH-OUT: charge=0 (role killBonus)" = #134's missing
penalty), and the death-cost block was skipped.

The analog DOES exist: Mission::GetScenarioRole(name) (MISSION.h:162) walks
scenarioRoleChain -- the same dictionary BTL4Mission fills via AddScenarioRole()
when it parses the role pages, whose own comment says the WinTesla base exposes
it.  Same lookup, same key.  Falls back to Role::Default when a creation
message names an unknown role (shipped content authors exactly one page), and
logs BOUND/NULL so this cannot fail silently again.

Benched cross-node:
  role binding    player 2:1 BOUND, player 3:1 BOUND
  KILL AWARD      505.88  (was 4.88)   <- chart's +500, verified
  death cost      victim total -500.00 <- chart's -500
  inflicted       still tracking, killer total 1017.32 kills=1

The -500 on an ORDINARY combat death is AUTHENTIC, not a bug: the binary's gate
is advancedDamageOn alone (@004c05c4 tail: `if (player+0x264 != 0) { -role+0x20 }`),
verified in the decomp.  It only shows now because the role finally binds.  It
also reconciles the chart's two death rows: an EJECT costs -500 (death) plus its
self-kill negating its own ~500 award = -1000, and an ammo death costs -500.

CORRECTION to my own earlier note: returnFromDeath=1000 is NOT the chart's
"+1000 starting the game" -- role+0x28 is a lives/return gate (`if (< 1)` ->
mission review, else respawn).  The 1000 is coincidence.  That row is still
unlocated and is most likely console-side.

Joe DiPrimaandClaude Opus 5 27721754da scoring: restore the type-0 INTERCEPTOR -- per-hit inflicted credit was live all along
Players reported scoring and K/D going screwy on 4.11.817.  Cause: build 787
(#45/#134) retired the port's per-hit inflicted crediting as an "invention",
on the strength of a KB claim that the type-0 score handler was dead code.
That claim was wrong.

BTPlayer overrides Dispatch -- vtable @00513300 slot 3 = FUN_004bffa0 -- and
splits type 0 off BEFORE base dispatch:

    if (msg->id == 0x16 && msg->type == 0)  FUN_004c0200(...);   // ScoreInflicted
    else                                    base dispatch;

@004c0200 names itself in its own Verify string
("BTPlayer::ScoreInflictedMessageHandler") and computes
CalcInflicted(basis) -> negate if target==self -> x (targetTonnage/ownTonnage)
-> accumulate into +0x278.  ScoreMessageHandler's type-0 arm Verify-rejects
precisely BECAUSE this interceptor guarantees type 0 never reaches it.

The port had the handler, faithfully reconstructed, and no interceptor -- so
Block B's inflicted reports all landed in the rejecting arm and banked 0.
Per-hit damage credit was silently deleted.

Independently corroborated by the ORIGINAL MANUAL'S SCORING CHART (filed as
reference/manual/scoring_chart.webp, from Lynx): "+1 each damage point scored
on opponent's armor" and "-1 each self-inflicted point of armor damage" -- the
negate-if-target-is-self arm exactly.  Without that chart the dead-code note
would probably have stood.

Verified (scratchpad/night13/scoreverify.sh, cross-node kill, 2 nodes):
  type-0 Verify rejections   0   (was firing on every non-lethal hit)
  inflicted score rows      83   awards 0.98..25.00, all positive, tracking damage
  kill path un-regressed    type=2 award=4.88 kills=1, victim respawn x1

KB: combat-damage.md report B and the score-model paragraph rewritten, with
the full chart and THREE unreconciled rows flagged [T4] -- flat +500 kill vs
the benched 4.88, +1000 at game start, and -1000 eject / -500 ammo (which
would live in ScenarioRole::specialCaseDeathPenalty @role+0x20, read by the
port but authored nowhere in shipped content).

KNOWN, NOT FIXED HERE: in MP the running total does not persist -- currentScore
is flushed to the operator console and ZEROED (btplayer.cpp ~1219) because the
binary treats it as a console DELTA.  Restoring the credit makes that very
visible (bench: totals climb to ~35 then reset).  Needs its own decision; the
chart's "+1000 starting the game" implies a persistent total lives somewhere.
