CNSA 2.0 Deadline Ladder Calculator

For a supplied inventory of systems (system class, asset type, deployment date), computes the applicable CNSA 2.0 migration deadline, days remaining, the earliest binding constraint, and a FIPS 140-2 Historical-list exposure flag. Every deadline is declared below with a source citation, so a regulatory date shift is a data re-pin, never a code change.

⚠ NOT a security scanner, NOT a cryptographic audit, NOT legal advice. Structural date math over your own supplied inventory only. Findings are asserted — verify current NSA CNSA 2.0 and NIST FIPS 140-2 guidance against official sources before acting.

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 `compute_pqc_deadline_ladder`. Task: Per-row CNSA 2.0 post-quantum migration deadline for a supplied system inventory (system class, asset type, deployment date): applicable deadline, days remaining, the earliest binding constraint, and a FIPS 140-2 Historical-list exposure flag.
Call it with arguments: {"policy_parameters":{"reference_date":"2030-12-30","inventory":[{"row_id":"KE-1","system_class":"commercial-fin","asset_type":"key-establishment","deployment_date":"2024-01-01","fips_140_2_certified":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.
