+## Exact execution
+
+Run logs/selfgate-20260905-121039-477-neftet-validation-r2, clean source
+recorded by run.json; PID27128, start10:10:39.9107720Z, final checkpoint
+10:11:40.8023302Z. Same route-477-neftet-validation.txt/session-v10, timeout420s,
+one background command, client/runner exit0, route complete and graceful
+logout confirmed. Both clients absent afterward. All agents paused during
+graphics; no build/test overlap. ACE UDP9000 PID13340 up before launch.
+No retail client touched. Fresh login saved at8763000F, teleloc8763000E;
+owner's exact crash trajectory remains unknown. Twelve press/release pairs
+are workload, not twelve proven airborne jumps. Same profile: High,
+near4/far25, MSAA4, anisotropic16, A2C1, maxCompletions4,1600x900,
+ImmediateKhr,RX9070XT/driver2.0.395, recipe10pak unchanged. Resize matches

+No persistent layer/registry/driver changes.
+
+## Result and boundaries
+
+Across BOTH complete logs: zero SYNC-HAZARD, Validation Error, VUID,
+ErrorDeviceLost, unhandled-exception or abandoned-shutdown matches. All three
+previous native hazard families disappeared. Stderr retains33 VFX warnings:
+one missing PhysicsScriptTable and32 missing effect-pose messages, not native
+validation errors. Windows12:10:39–12:12:30 Application1000/1001/1026 matches
+for AcDream/LiveKernelEvent/WATCHDOG=0; System4101=0. Original AMD reset
+causation and recurrence safety are NOT proven by this single clean run.
+
+Five checkpoints, failures0; all materialized/visible, normalWorld=true,
+portalDrawn=false. Login complete=false before next teleport cancels it;
+four Neftet checkpoints complete=true/cue=false. Final gen2/8763000E,
+601 visible/2601 total, transit owners idle; pending publication/retirement,
+backlogs, staged uploads and warmup0. Disabled shadow/oracle zeroes are NOT
+conformance proof. Validation FPS is NOT #481/C2 performance evidence.
