Craftmark Pilot-ready prototype

Evidence methodology

Verification methodology

Craftmark shows how information is supported so buyers can understand the source, review status, and limits of each public claim.

Pilot methodology statement

Craftmark evidence levels describe the source and review status of information. They are not a guarantee of product quality, delivery, solvency or transaction outcome.

Policy version: draft

Public labels

Evidence levels shown on Craftmark

self_declared

Self declared

Source
The maker supplied the information directly.
Review status
Craftmark has not reviewed a supporting document for this claim.
Limitations
Use this as maker-provided context and check whether stronger evidence is available.
document_provided

Document provided

Source
A supporting document was uploaded privately.
Review status
Craftmark records the document metadata but does not publish the file.
Limitations
The public page can summarize the document type and metadata, not the full private document.
platform_reviewed

Platform reviewed

Source
Craftmark reviewed the claim against an internal checklist.
Review status
A reviewer, review date, status, and limitation note are recorded.
Limitations
The review describes available evidence; it is not a promise about product quality or delivery.
independent_third_party_certified

Independent third-party certified

Source
An independent certificate or public register reference supports the claim.
Review status
Craftmark records the certifier, reference, review date, and relevant expiry when available.
Limitations
Public readers should check the scope, expiry, and certifier limits before relying on the claim.

What public pages must show

  • The exact evidence level behind a public claim.
  • The date last reviewed, when a review exists.
  • Any relevant expiration or next-review date.
  • Whether the information came from the maker, a document, Craftmark review, or an independent third party.
  • A plain-language limitation note.

What public pages must not show

  • Private evidence documents or storage links.
  • Personal identity documents.
  • Internal reviewer notes.
  • Raw risk scores.
  • Unsupported origin, sustainability, ethical, or compliance claims.

What a Craftmark review is, and what it is not

Reviews are deliberately narrow. Stating the boundary plainly is more useful to a buyer than implying a check that did not happen.

A review reads documents, it does not inspect workshops

During the pilot, every check is manual and desk-based. A reviewer reads what the maker submitted and records what that document does and does not show. Nobody visits the workshop, tests a material sample, or audits a supply chain.

A review covers one claim at one point in time

Each reviewed claim carries the date it was last reviewed and, where relevant, when it should be looked at again. A certificate that was valid in March may have lapsed by November. The date is published so you can judge how current the record is.

There is no single trust score

Craftmark does not compress a workshop into one number. Averaging a well-documented timber-origin claim with an undocumented durability claim would hide exactly the difference a buyer needs to see. Claims are shown individually, each with its own level.

Supporting files stay private

Public pages show a document's filename and SHA-256 checksum, never the file. Suppliers, pricing, and internal reviewer notes are not published. A buyer in a dispute can ask the maker directly for the document and check the checksum against the published record.

Corrections

If something published here is wrong, it should be reported and corrected rather than argued about. Anyone can flag a public page: Report incorrect information
