# ADR-004 — Derive Public Claims from Versioned Evidence

**Status:** Accepted (retrospective)  
**Date:** 2026-07-20

## Context

Offensive-AI performance claims are easy to overfit or report without reproducible evidence.

## Decision

Headline claims must be recomputed from committed corpus, ground truth, and receipts. Anti-fitting, provenance, and claim-verification gates are architectural product controls.

## Consequences

Repository size and CI cost increase, but claims are auditable. Raw sensitive transcripts may be withheld, so documentation must distinguish re-derivable graded verdicts from full raw reproduction.
