Quadriga
Quvant structures hypothesis, critique, synthesis and verification into an observable process, with evidence, declared limits and an exportable record.
Isolation of the last function
The Blind Validator receives the original case and the candidate conclusion, not the debate that prepared it. It is not shown that every other signal is kept out, or that the whole barrier after synthesis is verified.
Evidence System
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.
Conclusions may include confidence signals and conditions of validity. Formal score calibration is a product direction, not a current performance claim.
Assisted pilot
We verify Quvant on a real workflow with question, evidence, criteria and result format agreed before work starts.
