description: "Adjudicate a material or disputed factual, comparative, SOTA/frontier, status, completion, causality, or delivery claim against current primary evidence. Use when deciding whether work is actually done, a claimed improvement or leading position is supported, a stated cause is proven, or source, merge, release, deploy, and live behavior are established. Do not load merely because routine implementation reporting should remain truthful."

# Evidence and Claims Standard

Make the strongest claim current evidence supports, and no stronger. Read
[references/claim-evidence-method.md](references/claim-evidence-method.md) before
assessing a material or disputed claim.
Use [references/claim-dependency-revision.md](references/claim-dependency-revision.md)
when premises change over time, and
[references/assurance-cases.md](references/assurance-cases.md) for a high-impact
multi-layer claim.

## Method

1. State the claim precisely enough to be falsifiable.
2. Split compound claims and separate source, review, checks, merge, release,
   deploy, and live behavior.
3. Identify the authority, subject, revision, observation time, and evidence
   required for each claim.
4. Inspect current primary evidence; treat memory, summaries, agent consensus,
   and self-authored status fields as leads only.
5. Test plausible contradiction and staleness paths.
6. Assign `supported`, `refuted`, `unknown`, or `partially supported`.
7. Report residual uncertainty and the narrowest next evidence that could
   change the verdict.

Do not turn unavailable evidence into success or failure. A timeout, missing
permission, absent observation, or unrun check means unknown unless the
authoritative contract proves otherwise.

## Completion claims

Before saying `done`, `fixed`, `converged`, `shipped`, or an equivalent:

- bind the terminal condition before evaluating it;
- verify the exact candidate or live subject named by the claim;
- require evidence that exercises the claimed behavior, not merely nearby
  files, prose, or a self-declared status;
- check that no open finding contradicts the terminal; and
- stop at the lifecycle layer actually proven.

## Output

When claim adjudication is the requested job, produce a standalone
**Claim-Evidence Record**:

- **Claim** — one falsifiable statement.
- **Verdict** — supported, refuted, partially supported, or unknown.
- **Subject** — exact artifact, revision, environment, and time where relevant.
- **Evidence** — primary observations and what each proves.
- **Contradictions checked** — material disconfirming paths considered.
- **Boundary** — nearby claims the evidence does not establish.
- **Next evidence** — only if it could materially change the verdict.

When this Skill supports another requested artifact, integrate the applicable
verdict, evidence, boundary, and uncertainty into that artifact instead of
emitting a second report.

## Boundaries

- This skill governs what may be claimed; domain skills define what must be
  built or tested.
- Use `delivery-standard` for delivery mechanics and
  `risk-matched-verification-standard` for nondeterministic verification design.
- Use `critical-analysis` when several explanations remain credible.
- Do not demand ceremonial evidence that cannot change the claim.

## Routing examples

Use for “is this migration complete?”, “did this deploy reach production?”,
“is this system really state of the art?”, “does the evidence prove this
claimed cause?”, and “audit this executor report.” Do not route a request that
merely asks to implement a known code change unless it also asks for a material
status, comparative, or completion judgment.
