+## DAY-2 ADDENDUM (2026-08-04): eject epilogue + the stale-tracker sweep + #108/K-D
+
+### Settled today (all committed, tip 0bd9bb6+)
+- Eject FINAL: strict binary model shipped (soft keys never eject; Panic/numpad/
+  Backspace do; invite lamps decoded -- conds 4/5 = WEAPON ammo/jam purge invite,
+  cond 6 = bus invite via !HasVoltage; hysteresis tried+REMOVED, flap is authentic;
+  MarkGeneratorOut bridge removed -- state 4 = the thermal breaker, destruction
+  touches nothing electrical @0049c9a8). TechStatus bit table in decomp-reference.
+- #119 leak-voice stutter: AUTHENTIC (wooHoo latch authored all-zeros + no armer
+  in the image; the hunt at drained tanks clips the phrase-sequenced voice; our
+  only real bug was 2x cadence, already fixed). Deterministic leak scalpel added:
+  BT_KILL_SUBSYS partial form "Condenser4=0.5".
+- Tracker STALE sweep: #80 (crits -- landed a5fb96a 07-29, re-verified live:
+  [critroll] chance=0.01+0.7*lvl^2 byte-extracted) CLOSED; #2 (experience --
+  wired 07-20, [exp] sentinel live) CLOSED; #22 marked awaiting-verification
+  (respawn ammo-refill receipts in tonight's logs).
+
+### IN FLIGHT: #108 ghost recurrence + the K/D accuracy report (SAME ACTION)
+- #108 hypothesis: per-entity replication dropout on one node (miss death mode +
+  wreck gstate + respawn teleport together -> frozen ghost at the old spot while
+  hits register elsewhere). Lead mechanic: the wreck SINK (-8u underground) may
+  make the entity interest-culled for distant nodes; if re-interest never fires
+  after the respawn teleport, that node's replicant freezes forever. UNPROVEN --
+  693 field logs lack entity ids and every discriminating marker is env-gated.
+- K/D inaccuracy (night-11 report, build 716): the tally/credit receipts
+  (PLAYER_DEAD matchlog rows, [score] panel DRAW probe) are ALL env-gated off in
+  field builds -- logs show only roster rebuilds. Cannot confirm or deny from
+  the field data. NOTE: K/D columns are replicated state; a #108-style stream
+  dropout would corrupt both ghosts AND tallies on the same node -- one cause.
+- THE ACTION (next block, before cutting 717): make field logs self-diagnosing:
+  1. players/play_steam.bat (+join*.bat): set BT_MATCHLOG=1 (or a curated
+     death/score subset if per-shot DMG volume is too hot -- check matchlog.hpp
+     categories) + BT_SCORE_LOG=1.
+  2. Entity IDs on the ungated render lines (wreck swap / MakeMechRenderables /
+     RemakeEntity -- btl4vid).
+  3. NEW ungated [ghost] staleness detector: a replicant whose last-applied
+     update record is > N s old while not buried -> one line with entity id +
+     age + last-known position (the #108 indictment line).
+  4. Un-gate (or default-on) the respawn un-wreck line.
+  Then 717's night-11 logs convict #108's mechanism and settle the K/D claim.
+
+### Next-session queue (post-717-cut)
+1. The instrumentation block above -> cut 717 -> field night.
+2. #35 Owens laser crash; #126 invisible peer fire; #89 splash; #92 Loki feet;
+   #73 (check against the #124 triangle-pick fix -- likely closable).
+3. #118 last tail: MP console notice delivery audit.
