Provenance You Can Actually Check
Prove exactly who authored every claim, barrier, and hazard in your safety case — and prove the record of it hasn't been altered since.
SHA-256 Hash Chain, Not Just a Log File
Every entry in the audit log is cryptographically chained to the one before it — the same principle a blockchain uses, with no network required. Hand-edit, delete, or reorder any past entry and every hash after that point stops matching, which a one-click verification catches immediately. It's a specific, checkable property: not "we keep a log file," but "we can prove the log file hasn't been altered."
The AI Boundary
When relying on AI to accelerate engineering, regulators need to know what was machine-generated and what was verified by a human. Every piece of AI-drafted text in SAFOPS is tagged in the underlying data structure — by field, not just by record — until formally reviewed and signed off by a qualified engineer.
Full Traceability
Every change to hazard data is versioned with who made it, when, and — for AI-assisted fields — what prompt version drafted it. Export the full, verifiable trail for a regulator — ONR, HSE, ORR, or your own internal compliance reviews.
Evidence Management, Not Just Storage
Substantiation evidence is linked directly to the safety measure it supports, not filed away in a separate folder structure hoping someone remembers the connection. Each barrier's evidence carries its own status, so a gap in your evidence management shows up right on the diagram where it actually matters, not three systems away.
