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- combat-damage: old task-#60 kill-score section marked SUPERSEDED by the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.
