Research evidence

PLLM records source claims, clean-room fidelity, native implementation agreement, compiler coverage, runtime support, generation quality, matched benchmarks, assurance, and deployment observations separately. Missing evidence is unknown; it is not a zero result.

Accepted records live under docs/evidence/. Each record keeps its environment, workload, software revision, and limitations. Canonical full benchmark records use pllm.benchmark_result.v1; EvidenceRegistry retains positive, negative, and explicitly unavailable results and queries only exact recorded cohorts. A result does not apply to a changed component, plan, model, parameter, or deployment unless a new validation explicitly connects them.

Keep negative and unavailable results in the record. not_refuted means only that the named attack failed within the recorded budget.
