Solutions
Three high‑risk action surfaces. One verification pattern.
Each solution ships a procurement‑friendly ticket path: DSSE → packet → offline replay, with deterministic outcomes (PASS / FAIL / HOLD).
Action surfaces
Receipt → Permit → Gate
Different industries. Same safety invariant.
Where side effects can happen, evidence must be replayable and policy must be enforceable. Missing signatures or missing pointers must yield HOLD.
Procurement‑friendly
Each page maps risks → control points → attachable evidence packs.
Agentic execution safety
No permit, no side effect. Fail‑closed controls for tool‑using agents and privileged I/O.
Clinical admissible automation (CTC)
Permit‑to‑pay receipts for AI‑governed billing — replay‑verifiable evidence from authorization to clawbacks.
