+- ✅ **Combat SCORING feed** (KILLS/SCORE) — DONE (commit 34aaa7d; scoring-feed-decode workflow). The
+  scoreboard read 0 for 4 reasons (none was handler logic — the ScoreMessage/VehicleDead/ScoreInflicted
+  handlers were already reconstructed): (1) no producer — added the posts (per-hit ScoreInflicted at the
+  beam/projectile dispatch; KillScore at the TARGET-DESTROYED edge; senderMechID = the VICTIM so the local
+  player is credited via the !=our-mech branch; dispatched to GetMissionPlayer()); (2) cross-family Mech
+  offsets → GetPlayerLink() + tonnage/bias stubs; (3) NULL scenarioRole → CalcInflictedScore returns the
+  neutral (damage+bias); (4) ownerless-dummy null-guards. Plus the **databinding**: the PilotList read
+  KILLS/DEATHS at raw offsets → repointed to the compiled members via BTPilotKills/BTPilotDeaths bridges.
+  **⚠ ROOT-CAUSE of the empty scoreboard: the PilotList SELECT-TARGET highlight did a raw-offset deref
+  (`*(local+0x284)` then `*(tgt+0x190)`) that AV'd on our layout — caught silently by the SEH GuardedExecute,
+  aborting Execute BEFORE the KILLS/DEATHS draw. Replaced with BTPilotIsSelected (accessors).** And the
+  10s console flush now only zeros currentScore when a console host exists (solo keeps the running score).
+  **Verified: SCORE climbs +5.83/hit → 164; on the kill the Comm roster shows KILLS=1.** Follow-ups: DEATHS=1
+  is a pre-existing spawn/respawn-handshake artifact (not the producers); RANK=-1 is CalcRanking's non-scoring
+  mark (Plasma serial surface, invisible on dev); MP VehicleDead + tonnage/role registry remain. Env: BT_SCORE_LOG.
