Escrow driver file mapped into the RESPA skeleton

The simpler sectioned layout for the same moment. The decoded driver fields sit on the left, the learned RESPA escrow skeleton on the right, and each mapping line ties a native driver field to the skeleton slot it supplies. The header record carries the analysis, and the disbursement-detail records supply the escrow account history.

Represented data. Static concept mockup for review. Field names and the column layout follow the demo escrow driver fixture (record types EH and ED, loan 4400000000, servicer "Cornerstone Home Loans"). Values are decoded verbatim from that record. Confidence scores, the skeleton, and the exception dispositions are illustrative stand-ins, not live Onboarding Engine output.

The sectioned fallback trades the statement thumbnail for clarity: one lane of decoded driver fields, one lane of skeleton slots, and a mapping line for each binding. Three disposition classes are visible. surplus_amount and delinquent_flag are soft exceptions, driver fields that are present but do not render on this shortage-path, non-delinquent record, dispositioned but not blocking. The zone-seed-derived-footer is a seed candidate carried over from the servicer's existing monthly mortgage statement, held at lower confidence for an explicit compliance confirmation rather than auto-accepted. The prior-year-actuals-line is a hard exception: the RESPA account history wants the prior year's actual escrow activity, but the projection-only driver record carries no last-year actuals, so it routes to a human against the system of record at Step 4.
