Epistemic Verification Protocol|5-Gate Pass

The source data may be wrong.
The agent is telling you exactly what it says.

You clicked a “Grounded by Nesatz” verification badge. This badge certifies that the synthesized claims, clinical ratios, and citations displayed in your application passed through an automated 5-gate deterministic validation firewall before reaching the screen.

What Upstream Registries Provide

Empirical Publications & Filings

Clinical trials, FDA labels, and scientific journals may contain upstream experimental error, small cohort sizes, or conflicting trial results. Nesatz does not rewrite primary literature or act as a scientific oracle.

What Nesatz Mathematically Guarantees

100% Extraction Fidelity & Math Invariance

The autonomous agent did not hallucinate numbers, invert response equations (ORR = CR + PR), swap codon alleles (KRAS G12C vs G12D), or drop qualifying caveats during synthesis.

The 5 Verification Gates

Every committed claim, node, and relationship undergoes these five non-negotiable checks:

GATE 1

Pre-Read Ingress & Syntax Sanitization

Strips invisible unicode injection attacks, control bytes, and unescaped script tags from source text.

Enforced
GATE 2

Epistemic Modality & Dimensional AST Audit

Calibrated NLI blocks unhedged claims (“cures”); AST solvers verify algebraic consistency ($ORR = CR + PR$).

Enforced
GATE 3

Pre-Write Schema & Monotonic State Guard

Preflight dry-run check strictly enforces 7-state lifecycle progression (DRAFT → UNDER_REVIEW → ACTIVE).

Enforced
GATE 4

External Registry & Span Provenance

Binds assertions to primary PubMed/NCT identifiers and exact SHA-256 excerpt hashes.

Enforced
GATE 5

Post-Write Read-Back Drift Quarantine

Immediately reads back physical storage state; quarantines any silent database mutation to UNDER_REVIEW.
