NEPA is a deterministic inspection infrastructure platform engineered for auditability, replay verification, and governance control. Designed for safety-critical environments where inspection systems must withstand independent scrutiny.
The NEPA platform processes sensor data through a structured, deterministic pipeline that produces inspection findings with full attributable provenance. Every finding references the exact engine version, configuration state, and sensor calibration record that produced it.
The system is designed not merely to detect — but to produce findings that can be independently validated, replayed, and defended in regulatory, legal, or procurement contexts.
The platform operates under a formal real-time latency contract. Time-critical detection and secondary analytics are separated by design, ensuring that control-path behavior is never degraded by reporting or logging activity.
Each processing lane maintains an independent watchdog. Latency exceedance events are logged and escalated without affecting adjacent lanes.
The real-time control path is isolated from analytics, logging, and reporting subsystems. No secondary process can introduce jitter into the detection pipeline.
The platform is validated under multi-hour sustained operational workloads at peak drone inspection throughput, with automated regression benchmarking on every release.
Eight independent processing lanes operate in parallel, each handling a dedicated sensor modality or processing function. Independence is enforced at the data, memory, and scheduling levels.
All inspection findings are stored with sufficient provenance to support independent re-derivation. The replay system allows any finding to be reconstructed from preserved sensor data using the original engine version and configuration state.
Raw sensor frames, processed representations, and derived findings are written to append-only storage with cryptographic sealing. No record can be modified without detection.
Byte-level deterministic replay reproduces every intermediate processing state. Auditors receive a signed attestation package alongside replay artifacts.
Before replay, the system validates that stored configuration hashes match the requested engine version. Mismatches halt replay and generate a compliance incident.
Every system event enters a hash-linked chain. Each block references its predecessor, making retrospective modification detectable at any audit depth.
NEPA integrates into existing camera-to-edge-to-cloud architectures. It is designed to operate on standard hardware and enhance existing analytics stacks without replacing them.
