🧬 UID Traceability & OTA Firmware Architecture
Extreme-Spartan Cognitive Industries Pvt. Ltd.
🔍 Overview
This system ensures every deployed ESCAPE-chip is uniquely identifiable, remotely updatable, and audit-traceable across its lifecycle. It combines:
- UID Manifesting
- OTA Firmware Delivery
- Edge AI Sync
- Compliance Logging
🧠 UID Manifest Structure
| Field | Format | Description |
| UID Code | HEX + Timestamp | Globally unique per chip |
| Sensor Map | JSON | LiDAR, GPS, IR, Thermal, Optical |
| Deployment Tier | Enum | [Pilot, PPP, Summit, Field] |
| OTA Status | Boolean | Firmware sync enabled |
| Compliance Tags | Array | ISO, PPP, NSDC, UID-Ready |
| QR/NFC Overlay | Embedded UID Access | For field scan & audit |

📡 OTA Firmware Architecture
| Layer | Framework / Protocol | Function |
| RTOS Base | ESP-IDF / FreeRTOS | Task scheduling |
| OTA Manager | HTTP / MQTT | Firmware push/pull |
| UID Sync Layer | JSON + QR/NFC | UID traceability |
| Cloud Bridge | AWS IoT / Azure IoT | Remote diagnostics |
| Security Layer | TLS + JWT | Auth & encryption |
| Rollback Logic | Dual Partitioning | Safe fallback if update fails |
