Expensive model inference happens off-chain; GenLayer certifies a bounded, semantically judged scorecard. Evidence architecture: score_run requires four content arguments, all verified against on-chain SHA-256 commitments before any validator sees the content: rubric_content — sha256 committed in create_benchmark sample_bundle_content — sha256 committed in commit_run task_manifest_content — sha256 committed in publish_version (same version as the run) run_manifest_content — sha256 committed in commit_run (run_manifest_digest) The sample bundle must be a JSON array of {task_id, input, output} objects. The task manifest must be a JSON object with a "tasks" array of {task_id, prompt} objects. Scoring verifies that every sample task_id exists in the manifest, binding the evaluated outputs to the canonical task inputs the model was given — not just an opaque output blob. The run manifest records claimed run provenance (model config, inference parameters, hardware). Its digest is committed at submit time; supplying the content at score time proves the provenance description was not changed after the outputs were seen. The sampling policy is enforced at score time against two requirements: 1. min_samples — absolute floor (sample count >= min_samples) 2. sample_rate coverage — floor derived from manifest size (sample count >= ceil(manifest_size * sample_rate)) Both must pass. Duplicate task_ids are rejected — repeated copies cannot satisfy either threshold. Coverage scales with the benchmark, preventing cherry-picking a small easy subset from a large manifest. The run manifest may declare an attestation path via attestation_url and attestation_digest. When present, both fields are structurally required and the digest is format-validated. Validators see the attestation reference during scoring and can independently verify the attestation document. The exact content supplied is the exact content judged — no truncation, no URL fetching. Storage approach: all state serialized to JSON strings. benchmarks_json: serialized list of benchmark objects (index = benchmark_id) versions_json: serialized list of version records (immutable) runs_json: serialized list of run objects (index = run_id) snapshots_json: serialized list of snapshot objects (index = snapshot_id) exemplars_json: serialized list of {benchmark_id, dimension, text} Evidence size limits (must be enforced before scoring): MAX_RUBRIC_SIZE = 4000 characters MAX_SAMPLE_SIZE = 8000 characters MAX_MANIFEST_SIZE = 8000 characters MAX_RUN_MANIFEST_SIZE = 4000 characters Content exceeding these limits is rejected at score_run time.
