FDIC Part 370 Output-File Validator

Validates the shape of your own 12 CFR part 370 deposit-insurance-coverage output file, the section 370.10 coverage summary report structure, against its published record layout: required field presence, malformed count or amount values, and a repeated ownership right and capacity code. Ties the file's declared totals to a supplied art-507 coverage recompute. A shape defect and a totals mismatch are two separate findings, never merged: a shape problem is checked first and routes to review, regardless of how the totals compare, and only a clean-shaped file with a totals disagreement escalates. Ownership right and capacity codes stay opaque strings throughout, exactly as in art-507, with no table of part 330 ownership categories held here. Emits a hash-anchored OpenChainGraph v0.4 artifact carrying a §27.4 gate-policy decision at a predictable pointer.

⚠ This tool holds no table of 12 CFR part 330 ownership categories or allowance rules, offers no deposit insurance advice, and is not a filing. It computes once when you press the button, stores nothing, runs on no schedule, and retains nothing. Small-buyer caveat carried forward from art-507: the population this reconciliation currently covers is zero institutions in the revenue-kanban sense; this validator is specified anyway because it is cheap and completes art-507 into the certification evidence pack.

    What this does not do

    It does not interpret an ownership right and capacity code, hold a table of 12 CFR part 330 ownership categories, or pull an art-507 result itself; you supply both the file rows and the tied recompute. It is not a filing tool and produces no section 370.10 submission format. A clean shape-and-tie-out pass is not a determination that the file would be accepted by the FDIC.

    ART-507 computes the insured and uninsured amounts by ownership right and capacity that this node's tied recompute is expected to carry. This node is the file-shape and totals-tie-out step downstream of it; it never recomputes coverage itself, only validates the file that reports it.
