Evidence Bundle Tier Labeler

Assembles a shareable evidence bundle around an artifact and stamps the tiered label it qualifies for — OCG-Verify, OCG-Execute, or OCG-Prove — computed purely from which §15 gates you declare passed for that artifact.

Tiered Label No New Gate Re-expresses Existing Proofs

🔒 All inputs are processed locally in your browser. No data is transmitted. Do not enter real personal data — use synthetic or anonymised inputs only.

⚠ This node does not re-run §1/§4/§18/§21/§22 gates itself. The five gate checkboxes below are your own declaration of prior gate outcomes for the referenced artifact — not independently re-verified here.

The tiered label adds no new gate and mints no new trust claim (SPEC.md §SIDECAR.1) — it re-expresses existing gate-pass results as a single naming, atop the gate suite that already exists.

Artifact Reference

Artifact tool_id

Artifact execution_hash

Proof refs (one per line — receipt/proof/anchor references attached to this bundle)

Section-27.2 human_accountability_records (optional, JSON array — consumed into a section-27.6 evidence bundle keyed to the artifact hash above)

Declared Gate Results

Envelope well-formed (§1)

execution_hash recomputes (§4)

Chain-execution valid (§21)

Mandate gates valid (§22)

Compute-integrity proof valid (§18)

Gate Provenance

Execution Hash (SHA-256)

Ask your agent

Copy this paragraph into Claude, OpenClaw, or any MCP-aware agent to run this exact tool, with this sample, and verify the artifact.

Run the AINumbers MCP tool `assemble_ocg_evidence_bundle`. Task: Assemble a shareable evidence bundle around an artifact and stamps the SPEC.md §SIDECAR.1 tiered label it qualifies for: OCG-Verify (envelope well-formed, execution_hash recomputes), OCG-Execute (additionally §21 chain-execution and §22 mandate gates hold), OCG-Prove (additionally a §18 compute-integrity proof verifies).
Call it with arguments: {"policy_parameters":{"artifact_tool_id":"art-04-agent-identity-attestation-checker","artifact_execution_hash":"sha256:aaaa1111","proof_refs":["receipt:art-04-envelope-check"],"gate_results":{"envelope_well_formed":true,"execution_hash_recomputes":true,"chain_execution_valid":false,"mandate_gates_valid":false,"compute_integrity_proof_valid":false}}}
Verify before trusting: call `verify_execution_hash` on mcp.ainumbers.co (https://mcp.ainumbers.co/mcp) with the parameter `claimed_hash` set to the returned `execution_hash`, passing the full artifact the run returned (the object containing `policy_parameters` + `output_payload` + `execution_hash`; equivalently `policy_parameters` + `output_payload` with `claimed_hash`), not the bare hash string.
Return the ledger link https://ledger.ainumbers.co/ so a human can re-verify without contacting us.
