 The same-frame double-credit this closed (direct+splash lethal pair racing the deferred death
 transition) is gotcha §25 — the death mode now flips synchronously inside the damage pass,
 matching part_012.c:14761.

+## Application control is OWNER-ONLY — the replicant player StopMission leak (2026-08-12) [T2]
+`Player::ManageApplicationStatus` (the 3.0s mission-end fade countdown → the second StopMission →
+`Application::Stop()`) is now gated `GetInstance() != ReplicantInstance` (PLAYER.cpp). Un-gated, a
+REPLICANT player copy — whose simulationState mirrors the remote master's MissionEndingState
+through its record header, and whose fadeTimeRemaining was never armed (≤0 at first tick) —
+dispatched StopMission instantly and killed the mission loop before the fade could render. On an
+8-player steam node ANY of the 7 replicant copies cut the end window to ~one record heartbeat:
+the FIELD half of #156's "no fade". Same authority discipline as scoring (masters emit, mirrors
+display); receipts: `[fade-clk]` single 124-tick countdown + phases 1→5 (`fade_bench.sh`).
