In plain terms: Before any AI output becomes a real decision, it climbs a ladder
of checks. Automatic checks establish the sources, applicability, confidence, and
geometry evidence first. Responsible engineers and external authorities enter where
the decision requires them, and the final approved result is signed and recorded.
What it does
L6 applies cost-asymmetric checks in order. “Cost-asymmetric” means the fast, deterministic checks run first. Reviews that require an engineer, class society, or regulator enter later, after the evidence has already been checked. This protects specialist review time while preserving human authority. This is the .The gates, in order
Where human authority enters
High-risk engineering decisions reach responsible-engineer review at T5. Class-touching or USCG-touching decisions also carry the T6 external-review requirement. T7 signs and records the approved result. These requirements are part of the decision path, not optional interface settings.If a gate fails
If any gate fails, the proposal does not become a decision. The failure is logged with its reason, and the engineer sees exactly what is missing. Nothing half-verified slips through.What L6 outputs
