SLATE Securities-Loan Report Field Validator

Field-level structural validator for a covered-securities-loan report record against the FINRA Rule 6500-series field spec (loan terms, rate, collateral type, counterparty) that FINRA Rule 6540 -- FINRA's implementation of SEC Rule 10c-1a securities-lending transparency reporting (SLATE) -- requires. Honestly scoped in the art-397 pattern: this schema-validates structurally (required fields present, enum membership, numeric/date parseability) and is explicitly NOT a full SLATE conformance engine -- no cross-record consistency check, no regulatory-timeliness check. Validate-never-transmit: never calls fetch, never calls an RNSA, never simulates submission -- readiness is not submission. Reporting compliance date is 2028-09-28 per the SEC's 2025-12-03 exemptive order (post-remand of NAPFM v. SEC, 5th Cir., 2025-08-25) -- re-verify against a then-current SEC.gov release before treating that date as load-bearing.
