# Pattern: Claims Substantiation Gate

**Summary:** Keep a register of every public statement about what an AI system does and how well:
accuracy, fairness, safety, autonomy, "AI-powered" capability. Each claim is a row that cites the eval
run supporting it, the population and conditions it was measured on, and the date. A gate blocks
publication of a claim without live evidence, and every model release reruns the cited evals and
flags any claim the new version no longer supports. It is an eval gate pointed at marketing copy,
sales material and the accuracy figures declared in the instructions for use.

> **In short**
> The Claims Substantiation Gate is an assurance control that registers every public statement about
> what an AI system does and how well, and ties each claim to the eval run that supports it. It
> solves claims that outlive their evidence, or never had any: a regression ships while the old
> accuracy figure stays published. Use it wherever product pages, sales decks, tenders, model cards
> or instructions for use state how accurate, fair, safe or autonomous a system is. Each row records
> the exact claim, where it appears, the eval suite and run, the measured value and its interval,
> and the population measured. A gate blocks publishing any claim without live evidence, and every
> model release reruns the cited evals and flags claims the new version no longer supports. Its
> illustrative mappings include EU AI Act Art. 3(12), 13(3)(b)(ii) and 15(3), FTC Act s. 5,
> Directive 2005/29/EC Art. 5 and NIST AI RMF Measure 2.3 and 2.5.

## Objectives
Say only what the evidence supports, for the population the claim describes, and keep saying it only
while it stays true; and be able to show, for any claim, what supported it on the day it was made.

## Target users
AI governance engineer, product marketing, sales enablement, ML engineer, legal and consumer-law
counsel, investor relations.

## Impacted stakeholders
Customers and consumers, deployers who rely on the provider's figures, investors, consumer-protection
and financial regulators, market surveillance authorities.

## Relevant principles
Give every control teeth; instrument the build to produce its own proof; start from a named failure
mode or harm.

## Context
Product pages, sales decks, tenders, investor materials, model cards and instructions for use all say
how accurate, fair, safe or autonomous a system is. The copy is written once and owned by marketing;
the evidence is produced by ML and changes with every release. Regulators read that copy. The FTC's
Operation AI Comply announced that "there is no AI exemption from the laws on the books" [1]; its
Workado order followed a claim of 98% accuracy for an AI-content detector that testing put at 53% on
general-purpose content, and requires competent and reliable evidence for such claims [2]. The SEC
settled with two investment advisers over false and misleading statements about their use of AI [3].
Under the EU AI Act, the intended purpose itself is defined partly by the provider's "promotional or
sales materials and statements" (`Art. 3(12)`), and for high-risk systems the "levels of accuracy and
the relevant accuracy metrics" must be declared in the instructions for use (`Art. 15(3)`), stating
the level "against which the high-risk AI system has been tested and validated"
(`Art. 13(3)(b)(ii)`) [4].

## Problem
Claims outlive the evidence that once supported them, or never had any.

- **Forces.** Marketing wants a simple number; the honest number has an interval and a population.
  Evals are run on the data at hand, not on the population the claim describes: Workado's detector
  was trained on academic text, and the claim failed on everything else [2]. Vendor figures get
  repeated as if measured in-house. Deception, in the FTC's policy statement, is a representation,
  omission or practice likely to mislead a consumer acting reasonably, and material [5]; the EU's
  Unfair Commercial Practices Directive and the UK's Digital Markets, Competition and Consumers Act
  2024 prohibit unfair commercial practices in general terms [6] [7].
- **Failure mode.** A regression ships and the old accuracy claim stays on the website. A fairness
  claim rests on a vendor brochure. An authority asks what supported a statement made last year, and
  the only answer is the slide it appeared on.

## Solution
Register the claim, bind it to evidence, and gate both publication and release on the binding.

1. **Register every claim.** One row per claim: the exact text, every place it appears (URLs,
   documents, the instructions for use, the model card), the system and version, the metric, the
   claimed value, the owner and the status. "AI-powered" and "autonomous" are claims too: the row
   points at the registry entry that shows what the system actually does.
2. **Bind each claim to evidence.** The row cites the eval suite and run, the measured value with its
   interval, and the population and conditions of measurement. The AI RMF's test is the right one:
   performance "demonstrated for conditions similar to deployment setting(s)" (MEASURE 2.3), with the
   limits of generalisation documented (MEASURE 2.5) [8]. Substantiation rules run as code: the
   measurement population must match the claim's scope; a point figure is claimed only if the lower
   interval bound supports it; a comparative claim needs a paired comparison on the same data; a
   figure supplied by a vendor is marked provider-attested until re-measured.
3. **Gate publication.** Copy that carries a registered claim cannot be published, or sent in a
   tender, while the claim's evidence is missing, stale or failing. Unregistered quantitative claims
   are caught in review by the same rule that blocks unregistered systems.
4. **Gate the release.** Every model release reruns the cited suites. A claim whose evidence falls
   below the claimed value fails the release or opens a withdrawal task with a deadline and an owner;
   the declared accuracy in the instructions for use is regenerated from the same rows.
5. **Keep the history.** Withdrawn and amended claims keep their record (what was said, where, on
   which evidence, until when), so the organisation can show what it knew and when.

> **Example (illustrative)** A fraud product's website claimed a detection rate measured two model
> versions earlier on one country's traffic. Registering the claim showed both gaps: the evidence was
> stale and the population narrower than the copy implied. The claim was rewritten to name the region,
> the next release reran the suite, and a later retrain that dipped below the claimed value opened a
> withdrawal task before the new model shipped.

## Consequences
Public statements become evidenced, scoped and dated, stale claims are pulled by the pipeline rather
than by a regulator, and the declared accuracy in the instructions for use stays consistent with
marketing. The costs: marketing and legal must accept a register and a review step; honest claims are
narrower and carry intervals; and the rule on scope-matching needs judgement for qualitative claims,
which stay with legal review.
