Evidence and claim taxonomy

Separate a design contract, an implementation, its evidence, and a publication claim.

Axis	Meaning
Normative contract	Intended invariant; not implementation proof
Semantic adapter support	Model configuration lowers to neutral semantics
Compiler coverage	Named profile covers reported operators
Runtime support	Locked plan executes in tested implementation scope
Benchmark evidence	Measurements bound to environment, workload, and cohort
Generation quality	Predeclared output-quality result for model/workload
Privacy evidence	Scoped formal or empirical assurance result
Deployment maturity	Tested placement, authentication, recovery, and operations scope
Source-reported claim	Original publication statement, not PLLM result
Reproduction fidelity	Match to locked source/oracle in recorded scope

Unknown is never zero or pass. Every claim links exact artifact, date/version, cohort, limitations, and applicable assurance. Use research evidence records to inspect those scopes and limitations before repeating a claim.
