Validates an aggregate correspondent-banking data return (a bank's or money transfer operator's periodic counts of active correspondents, terminations, corridors and volumes by key currency) against an illustrative, profile-driven template: completeness, internal consistency, key-currency and concentration checks, plus a message-quality readiness roll-up from the existing address and LEI lint summaries. Everything runs locally on aggregate values only, so an institution can check a return before submission and nothing leaves the machine.
| Rule | Check | Outcome |
|---|---|---|
| REQ-* | Required fields per profile: period, institution type, pseudonymous code, at least one currency block with corridors; the pacific profile also requires USD, AUD and NZD | violation |
| COUNT-ROLLFORWARD | Closing active correspondents equals opening plus opened minus terminated or restricted, per currency | violation |
| CORRIDOR-SUM-* | Corridor sums equal the stated currency totals: counts exactly, values within a stated 0.5 percent tolerance | violation |
| PERIOD-SANITY | Real calendar dates, end on or after start, span at most 400 days | violation |
| STRING_LEAF_OUTSIDE_ENUMERATION | Aggregate-only contract: any string leaf outside the enumerations and the FI-NNN code pattern (a name, BIC, LEI or account identifier) is refused naming the JSON path only, never echoing the value | refusal |
| KEY_CURRENCY_SINGLE_CORRESPONDENT | Exactly one active correspondent in a profile key currency: the single-point-of-failure watch item | flag |
| CONCENTRATION_* | Top corridor share above 0.80, or Herfindahl-Hirschman index over corridor outbound-value shares above 0.50 | flag |
| readiness | Roll-up of supplied message-quality summaries (structure mix, valid LEI) into percentages and a band; reports not_supplied when absent | report |
The two per-message linters this node builds on are separate tools: the CBPR+ structured address linter (art-241) and the LEI payment binding linter (art-246). This node consumes only their aggregate summaries and never reimplements their rules.
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 `validate_cbr_data_return`. Task: Validate an aggregate correspondent-banking data return against an illustrative profile-driven template: required fields, roll-forward consistency, corridor sums, period sanity, key-currency and concentration flags, readiness roll-up.

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.
