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.
Formulates possible readings of the case.
Looks for assumptions, exceptions and weak points.
Organizes what holds and what requires further verification.
The validation step receives the original input and the synthesis, not the transcript.
Conclusions may include confidence signals and conditions of validity. Formal score calibration is a product direction, not a current performance claim.
