Maintain contractual balances, accruals, fees and due state

When to run this process

Trigger. Per transaction, daily accrual/date rollover, due date, approved term/status change or recalculation. Accountable owner. Loan-account administration lead. Accepted output. Auditable contractual balance, allocation basis, schedule and account due/status record.

Release or hold. Reject unsupported charges or replacement terms. Retain old state/history. Hold disputed calculation until contract/configuration source corrected. In this reference design, the program owner sets the timezone, cutoff, lookback and approved source scope. Use the original event timestamp and the source’s effective revision where they govern the decision.

Use the process for U.S. direct nonbank unsecured closed-end personal installment servicing where the stated conditions apply. Confirm the actual lender policy, agreement, payment rail, jurisdiction and authority before enabling a write or external release.

Validate the result independently

Human pitfall. Unverified rules, stale transaction, unauthorized charge, missing release, conflicting or provisional account effect. AI or agent pitfall. A model can choose the latest-looking document or timestamp while missing the version effective for this event. Verify the governing revision and time from the source.

Deciding evidence. Apply the version of the terms effective for the calculation period. A newer effective date can change accruals and due amounts on older events. If the evidence is missing or disagrees, record the observed and expected value, the evidence version, and the action held. Route the exception to Loan-account administration lead and use the task owner below for correction.

Tasks and acceptance checks

• Accept the governing terms and effective account events
• Calculate contractual balances, accruals, charges and due state
• Implement accepted relief, contractual changes or linked restoration
• Reconcile contractual state and release the affected version

Preserve stop where source permission or decision is missing. Use the lender’s documented authority for approval and release. Keep unsupported approvals and permissions unresolved.

Save and verify. Accepted calculation/implementation basis and explicit missing or contradictory inputs. Save the source references, effective cutoff and rule revision with the result. Authoritative terms, actual permitted change, effective date and actual input/decision evidence verified.

Human error to catch. Unverified rules, stale transaction, unauthorized charge, missing release, conflicting or provisional account effect. AI or agent failure to catch. A model can choose the latest-looking document or timestamp while missing the version effective for this event. Verify the governing revision and time from the source.

Hold and recover. Record the failed comparison and its evidence. Correction owner or source. Actual rule/contract, the “Apply, reverse and adjust loan payment entries” process posting or accepted decision producer. Return exact source defect and refresh only affected account/date. Keep accepted prior state and hold disputed effect. Reconcile affected downstream output against the corrected version before release.

Possible handoffs. Calculate contractual balances, accruals, charges and due state, Implement accepted relief, contractual changes or linked restoration, Reconcile contractual state and release the affected version. Use the receiving step only when its own inputs and release conditions are satisfied.

Accepted actual approved change and any required performance, payment credit or cancellation predicate. Inputs. Approved change, eligible scope, effective date and required evidence, Accepted monetary effects and prior contractual schedule, Current/prior loan payoff linkage if applicable, Exact accepted routine-change decision/effective version or independently authorized cancellation/prior-payoff linkage when applicable. Systems. Contract schedule and state-change log, source authorization and linkage.

Implement. Implement only accepted effective changes. Re-age/current status, extend due date or set modified schedule after exact source-required assent/performance. Apply SCRA eligible forgiven interest, periodic payment reduction and fee/rate changes without prohibited acceleration under approved debt/period. Separately recalculate monthly payment only where product/plan branch requires after actual applicable credit, including OneMain paragraphs 83 and 84(b)(ii) under separate conditions. Restore prior retained OneMain loan contractual state only for actual loan paid from valid canceled proceeds, with authority and payoff lineage. Accept the “Apply, reverse and adjust loan payment entries” process/the “Return borrower credit balances and remedy payments” process effects from actual owners. Accept the the “Decide the routine due-date request” step versioned authorized routine due-date decision and the “Record the eligible cancellation disposition” step authorized canceled-loan scope only for their separate applicable branches. Implement actual changed schedule or linked prior contractual state. Verify payoff-from-canceled-proceeds linkage, actual authority and exact existing prior loan before restoration. For the authorized routine-date or linked restoration branch, record an actual rejected or unresolved implementation against its exact decision version and send the owned outcome to the “Reconcile contractual state and release the affected version” step on the documented handoff. Preserve the prior authoritative schedule/contract version and state, the requested effective date, affected loan and fields, actual attempt or hold evidence, reason and repair owner. Generate controlled schedule/account-state changes from accepted instructions. Preserve manual authority choices and actual execution evidence.

For a failed or held result, validate case linkage and the unchanged authoritative basis before sending status to the “Reconcile contractual state and release the affected version” step. A failed attempt leaves the prior version authoritative.

Human error to catch. Unperformed plan, wrong eligible periods or linked loan, amount mismatch, failed implementation or unknown delegation. AI or agent failure to catch. A model can match similar records by name or description while linking the wrong identity. Require the source key and its corroborating record.

Hold and recover. Record the failed comparison and its evidence. Correction owner or source.

Hold until authority and underlying effects verified. Repair only affected account/period, recompute and reaccept actual state. Return incorrect due-date choice/effective version to the “Decide the routine due-date request” step or invalid canceled/prior-loan linkage to the “Record the eligible cancellation disposition” step. Repair affected actual state here and pass to the “Reconcile contractual state and release the affected version” step acceptance. Repair the affected implementation in the “Implement accepted relief, contractual changes or linked restoration” step after the specific defect or upstream input is corrected. Send the verified new outcome to the “Reconcile contractual state and release the affected version” step under the same case, preserving the failed attempt and all versions.

Reconcile contractual state and release the affected version

Read and assign. Loan-account administration lead handles per loan, accepted as-of state and affected downstream dependencies. Trigger. Calculated or implemented state, no-change path or corrected result. Inputs. Old/new contractual state and rule version, Calculation or authorized change result and actual posting/effect evidence, the “Implement accepted relief, contractual changes or linked restoration” step the documented handoff owned failed/held implementation with exact authorized case/version, affected loan/state, requested effective date, prior authoritative schedule/contract and state, actual evidence, reason and owner. Systems. Account state history and acceptance/consumer version log.

Implement. Compare expected and produced balance, due state and schedule, preserve prior versions and publish only accepted affected output. Keep open discrepancies owned. Send actual due/delinquency, correction, restoration and notice eligibility state only to relevant consumers. For CheckConnect, supply accepted state for the “Return borrower credit balances and remedy payments” process no-delinquency refund predicate when needed. Return accepted actual contractual date/schedule to the “Verify implemented due date and accept communication evidence” step and accepted actual linked restoration to the “Reconcile completed or outstanding cancellation effects” step only for the applicable decision/version. Return an owned hold or failed effect when applicable. Accept a verified the “Implement accepted relief, contractual changes or linked restoration” step the documented handoff record as implementation status while the prior schedule/contract and balance remain authoritative. Return the scope-matched held or failed result through H14 to the “Verify implemented due date and accept communication evidence” step for a routine change, or through H09 to the “Reconcile completed or outstanding cancellation effects” step for linked restoration.

Schedule and recover the workflow

Trigger on: Per transaction, daily accrual/date rollover, due date, approved term/status change or recalculation.
Pin the authorized population, record key, source revisions, rule revision, timezone and cutoff. Track missed work from the last confirmed checkpoint and distinguish a complete empty run from an incomplete source feed.
Compare terms_effective_at against the authoritative source for the same account, version and cutoff. Return the comparison, outcome, reason and next owner. Reject unsupported charges or replacement terms. Retain old state/history. Hold disputed calculation until contract/configuration source corrected.
Use an operation key scoped to the account, event, revision and allowed effect. Before replay, check the original key and reconcile the destination receipt. Revalidate only the affected scope after a documented correction.
Expected handoff: Auditable contractual balance, allocation basis, schedule and account due/status record. Escalate unsupported acceptance or authority to Loan-account administration lead.

Run the synthetic decision check

Apply the version of the terms effective for the calculation period. A newer effective date can change accruals and due amounts on older events.

Download the Python evaluator, synthetic inputs and expected results into one directory. Use Python 3.11 or later. The example uses the normalized field terms_effective_at with a frozen account identity, source and policy revision, cutoff and destination observation.

python3 validate_servicing.py --process reconcile-contractual-loan-balances

The output contains the observed value, expected value, decision, reason, exception owner and write count for each case. The exercise makes zero writes. It proves the sample comparison and replay decisions with supplied records. Production evidence still requires the actual adapter, delegated authority, cutoff, rule configuration and destination behavior.

Measure and operate the workflow

Track eligible items at the grain of each task above. Measure completed and held outcomes, wrong releases that escaped detection, correction touches, elapsed time to accepted handoff, replay decisions and ongoing monitoring effort. Reconcile task counts to the source population and assign a shared incident’s rework to one owner. The reference example provides no measured savings or throughput.
