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's min_samples is enforced at score time: the sample bundle must contain at least min_samples entries. 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. Scoring mathematics: equal-weight average of dimension bands. score_bps = round(sum(bands) / (4 * len(dimensions)) * 10000) """ from genlayer import * import json import hashlib import re _DIGEST_RE = re.compile(r'^sha256:[0-9a-f]{64}$') _URL_RE = re.compile(r'^(https?://|ipfs://)', re.IGNORECASE) #
