Model Risk Lineage Pack

Note: this is a single-node citation bundle, not a multi-step chain. Stage 1 cites the model-passport-lifecycle (art-450, art-451, art-453) and model-validation-cycle (art-488, art-489) artifacts by execution_hash. No step's output is recomputed by this bundle; it reads and packages what the two source chains already produced.

Compiles a model's current model-passport-lifecycle and model-validation-cycle artifacts, cited by execution_hash and never recomputed, into a single BCBS 239 SS II / RDARR-shaped bundle: inventory tier, outcome-analysis result, validation status, replication verdict, and test-battery result, each with its citing hash and producing tool. Each of the five stages is optional individually; a caller may not have every stage yet, and the pack reports which stages are cited and which are absent, never fabricating a missing one. No new gate logic, since the two source chains already carry their own gates; this pack is a read-after-the-fact bundler, not a re-router.

Not a validation opinion, not a model re-run, and not a regulatory filing. Every stage reference below is SUPPLIED by the user and treated as asserted: this pack performs no lookup against a live artifact store and does not itself verify that a cited hash corresponds to a real, still-valid upstream artifact. It has no bearing on whether the underlying model is fit for use and does not itself satisfy BCBS 239 or RDARR. SR 26-2 (superseding SR 11-7, effective 2026-04-17) scopes this pack to conventional quantitative models only; it makes no claim about gen-AI or agentic-AI systems.

Compile Model Risk Lineage Pack art-562-compile-model-risk-lineage-pack
Cites the model-passport-lifecycle and model-validation-cycle artifacts' execution_hashes into one BCBS 239/RDARR-shaped bundle: inventory tier, outcome-analysis result, validation status, replication verdict, and test-battery result. Each of the five stage references is optional; the bundle reports which stages are cited and which are absent.

Export Workflow Artifact
Download a §4-compliant workflow artifact with execution hash and step definition. Hash is deterministic over canonical {policy_parameters, output_payload} per RFC 8785/JCS.

Ask your agent

Copy this paragraph into Claude, OpenClaw, or any MCP-aware agent to run this whole workflow on the server and check one field that answers a real question.

Question: An examiner asks for this model's paper trail. How many lifecycle stages does the pack actually prove?
Run the AINumbers MCP tool `run_chain` with {"chain":"model-risk-lineage-pack"} and read `art-562-compile-model-risk-lineage-pack.stage_count_present`.
Verify: call `verify_execution_hash` (https://mcp.ainumbers.co/mcp) with `claimed_hash` set to `composite_execution_hash` and the full `composite_artifact`.
Ledger, for a human re-check: https://ledger.ainumbers.co/
PII rule: send synthetic or anonymised inputs only. The MCP server runs these kernels and logs no payloads.
