The hub's self-declared claim and the reference report with 137 vectors

A hub answers GET /v1/conformance with the classes it claims and a pointer to a report. The reference hub claims executor and has no report: self-declared. The reference report (claim verifier, 15 suites, 137 vectors, all passed on 2026-10-04) is the shape a certifier reads.

Schritte

  1. Ask the hub what it claims. report is null: a claim without a report is a self-declaration, which the note says plainly. conformance

  2. Validate the reference ConformanceReport produced by tools/run_conformance.py. The reference hub's validate checks the document against the schema file's root; this schema keeps its kinds under $defs, so today this call reports ok for any document, and `cookwala validate` (the CLI line) is the real check. validate

  3. Hash the report; this is the value a DirectoryEntry or a registry entry points at (scenario 091). hash

Ergebnis

You can tell a self-declared claim from a report, and you know a report proves behaviour on the vectors on one day, not safety in every kitchen (CERTIFICATION section 4). Next: 093 reads the operation vocabulary the vectors test.
