Product direction - formal calibration

Evidence System

The Quadriga process produces an exportable record for human review.

For teams operating in DORA, NIS2, EU AI Act and high-responsibility internal-policy contexts.

Evidence Ledger. A record with verifiable integrity, linked by a SHA-256 hash chain, that makes changes detectable against the export within the declared boundary.

To keep the previous discussion from steering the check, the Blind Validator receives the original input and the candidate conclusion, not the debate that produced it.

Synthetic interface example.

Blind Validator

The validation step receives the original input and the synthesis, not the transcript.

0.76Confidence signal

Conclusions may include confidence signals and conditions of validity. Formal score calibration is a product direction, not a current performance claim.
