Format and Interoperability · Area
Conformance evidence
Schemas, exact fixtures, diagnostics, and independent output agreement.
Points in this Area
5 PointsChecks govern writing, not authority
Stable Check syntax and evaluation output let consumers exchange compliance evidence without importing project policy into format validity.
The current format is the only contract
One HEAD contract gives implementations one observable behavior to reproduce rather than a compatibility matrix.
Fixtures pin observable behavior
Exact fixture outcomes are reproducible conformance evidence that independent implementations can compare.
The independent reader proves consumer agreement
Agreement from a separately implemented reader is evidence that the contract is reproducible outside reference code.
Portable files enable independent processing
Schemas, fixtures, ordering rules, and a second reader turn textual portability into observable interoperability evidence.
