KB housekeeping sweep: end-of-arc staleness purge (2026-08-06)

Corrections (wrong claims fixed + swept):
- open-questions: the DuckState 'no CODE consumer, authentic [T1]' verdict
  RETRACTED (consumer = the unexported posture block; squat clips shipped in
  BTL4.RES all along); the searchlight fog swap re-marked DONE (was 'STILL
  DEFERRED'); crouch index pointer updated.
- combat-damage: old task-#60 kill-score section marked SUPERSEDED by the
  report tail (BTPostKillScore retired).
- pod-hardware: crouch census rows -> COMPLETE; gauges-hud: 07-20 note
  (generators 'unreconstructed') re-swept.

New knowledge:
- reconstruction-gotchas #20: EXPORT-GAP BLINDNESS (4 incidents, 2 falsely
  T1; the byte-scan/named-member/RES-TOC/manifest checklist) + the
  verification-viewpoint bullet in #13 (the crouch capture errors).
- decomp-reference: master posture/crouch block offsets (+0x3f8/+0x79c, the
  myomers cluster) + 8 new bench env gates.
- rendering: beam-material decode (btfx brighten) + look-pass acceptance.
- experience-levels: crouch novice lockout in the +0x25c consumer list.
- build-and-run: the stale-link build ritual; test-harness: bench-script
  gotchas (both previously oral tradition).
- glossary: export-gap-blindness; multiplayer: crouch/searchlight ride
  existing records; subsystems: searchlight visuals pointer.

Status refresh: CLAUDE.md front + project-overview current-state -> core
gameplay reconstruction COMPLETE (774->801), polish phase, #60 census next.
Ledger addenda: INPUT_PATH row 6 complete; RESPAWN_REARM VehicleDead-sender
note. .gitignore: content/ bench artifacts (pngs/logs/eggs/exe) out of
status. checkctx CLEAN.

-is complete** ([[gauges-hud]]). The engine/renderer/HAL are done (WinTesla); AUDIO backend is now REAL

+## Current state (2026-08-06) — core gameplay reconstruction COMPLETE; polish phase
+Field-tested nightly at 4-8 pods over Steam (builds 4.11.622→801). Authentic + benched: the full
+SP+MP loop; per-panel mesh-true targeting/damage (+ crits, cylinder lottery, armour darkening);
+the 1995 SCORING model (kill awards + received penalties + panic cost — the id-0x16 report tail);
+death (blast/splash, wreck, burial) + respawn (full re-arm audit); locomotion (two-channel gait,
+gimp limp, knockdowns, CROUCH F4); the night kit (fog-swap SEARCHLIGHT F5 + beam cone); heat/
+power/myomers (incl. the seek-4 freeze); replication (masters/replicants, kill/death columns,
+ghost+skate field detectors); the Steam wire seam + build gate; the operator console/relay
+lifecycle; gauges/HUD; audio (real OpenAL backend + the AUDIO_FIDELITY trigger waves — footsteps/
+gait/alarms/impacts live in the field). [T2]
+**Remaining (polish + infra):** the #60 export gap census (NEXT — export-gap blindness has caused
