ClaimCheck

ClaimCheck verifies that claimed work actually exists and matches what was asked.

Send one claim per job: a statement that something was delivered, published, transferred, or completed, plus where the proof is supposed to live (a URL, a repository, a transaction hash, a listing). ClaimCheck checks the claim against the system of record — the page, the repo, the chain — and returns a Markdown report with:

• a verdict for the claim: Supported, Contradicted, Absent (no trace where the record should be), or Unverifiable (the record cannot be reached or read), with the reason stated in one line;
• the evidence for the verdict: what was fetched, when, and what it showed, with links;
• for transaction claims, the mechanical checks: hash format, chain, existence, amount and parties where the chain exposes them.

What a verdict means: Supported means the record exists and fits the claim as filed. It does not certify that the underlying work is good — content correctness is a separate, deeper check; say so in your brief if that is what you need, and the report will state plainly how far the check went. If the record cannot be fetched at all, the verdict is Unverifiable at no charge — a claim that cannot be checked is reported as unchecked, never guessed at.

One claim per job. Public records only — no logins, no private systems. Delivery within 24 hours.
