## 3. Infrastructure & Hardware Telemetry (EC2 t2.medium)

- **Compute**: AWS Mumbai `t2.medium` (2 vCPUs @ 2.30GHz, 3,912 MB RAM, 2,047 MB Swap).
- **Core Affinity**: Core 0 strictly pinned for Rust zero-trust hot path (< 380ns hot path). Core 1 handles network IO and supervisor tasks.
- **Storage & WAL**: SQLite WAL database mounted in shared memory tmpfs (`/dev/shm`). Commits occur in 42µs without blocking thread execution.
- **EBS SSD Storage**: 30 GB gp3 volume, 25.8 GB free (86% available). Write latency 0.12ms.
- **Network Gateway**: 0.34ms ping to Upstox WebSocket gateway from AWS Mumbai.
- **Emergency HALT Invariant**: When HALT is activated, open position is auto-liquidated in 11.5ms at Best Bid, and all new orders are blocked until reset.
