| Metric | Value | | :--- | :--- | | User Facing Impact | 45 minutes downtime | | Failed Sessions | ~12,400 simulation sessions crashed | | Data Loss | None (snapshots were read-only) | | Corrupted Caches | 3 shards required manual purge |
| Category | Finding | |----------|---------| | Firmware | Missing upper bound for DRA gain scheduling. v.1 had a hard clamp; v.2 removed it for “flexibility.” | | Validation | Stress test used linear load ramp, not step changes. Real-world step load triggered the flaw. | | Thermal model | Assumed homogeneous heat dissipation; hot spots exceeded sensor thresholds before reaction. | | Fail-safe logic | EDS triggered correctly, but memory write protection failed during shutdown → corruption. | vimu engine v.2 failed
The primary cause of the failure was a dependency mismatch between the Vimu Engine core and the hardware abstraction layer (HAL). | Metric | Value | | :--- |
Specifically:
On ARM-based NAS or Pi-like devices, when the SoC temperature exceeds 85°C or voltage drops below 4.8V, the engine’s hardware decoder may return a fatal error. Do not rely on the pop-up alone
