How to automate mortgage workflow controls and recovery
TLDR
Reconcile the destination using the original operation key, payload and policy version before retrying. Preserve the evidence chain, authority and exception owner, and distinguish a committed receipt, a conflicting request and an unresolved external state.
How do you recover an automation when a financial action may already have committed?
Reconcile the destination using the original operation key, payload and policy version before retrying. Preserve the evidence chain, authority and exception owner, and distinguish a committed receipt, a conflicting request and an unresolved external state.
Use the Secondary Marketing operation guide to connect this process with the surrounding work.
Set the trigger, owner and input contract
7 steps. Function: Capital-markets operations owner. Review or policy authority: Finance control owner / security owner. Cadence: Each change, daily checks and scheduled review. Count work per access change, exception or controlled job, not automatically per loan.
Required upstream records. Source intake and event history. Use the declared cutoff and hold the dependent output when a required record is missing, stale or unresolved.
Event contract. Preserve actor_id, role, authority_version, source_version, run_id, approval_id, incident_id, replay_key, release_id, plus source revision, event/effective time, observed time, input hash and the approved rule version. Map these keys to your provider’s field names and keep them with the run record.
Store the source manifest, cutoff, input hash, approved rule version and responsible function with each run. Save proposed work, review decisions and confirmed destination receipts separately.
Validate the result before the handoff
Process acceptance example. A destination commits a permitted write, but the response times out before the scheduler records success. Expected behavior: Read back by the original operation key before retrying. Preserve one committed effect and its receipt; route a conflicting payload under the same identity to review.
Compare the expected output with raw source records and the approved rule. Keep missing evidence unknown and assign a failed prerequisite to its owner. A successful extraction or submitted request does not establish a completed business result.
Build the workflow step by step
Access, audit, exception and continuity controls
7 steps. Function: Capital-markets operations owner. Review or policy authority: Finance control owner / security owner. Cadence: Each change, daily checks and scheduled review. Count work per access change, exception or controlled job, not automatically per loan.
Required upstream records. Source intake and event history. Use the declared cutoff and hold the dependent output when a required record is missing, stale or unresolved.
Event contract. Preserve actor_id, role, authority_version, source_version, run_id, approval_id, incident_id, replay_key, release_id, plus source revision, event/effective time, observed time, input hash and the approved rule version. Map these keys to your provider’s field names and keep them with the run record.
Measure the work. Record eligible events, active staff minutes, retained review, exceptions, repairs and run costs. Compare with the workflow your configured tools handle today. Track elapsed settlement waits separately from active staff time.
Process acceptance example. A destination commits a permitted write, but the response times out before the scheduler records success. Expected behavior: Read back by the original operation key before retrying. Preserve one committed effect and its receipt; route a conflicting payload under the same identity to review.

Schedule the workflow
Configure the schedule or event trigger in your approved automation environment. Keep the input location, source cursor, output location and exception queue explicit. Reconcile missed source events as well as normal arrivals.
Run Access, audit, exception and continuity controls at this cadence: Each change, daily checks and scheduled review.
Use only the authorized source manifest, cutoff and rule version. Owner: Capital-markets operations owner.
Follow each step in this guide and run its independent source comparison.
Return the accepted candidate, source references, rule/input versions and per-step checks.
Hold missing, stale, conflicting or unsupported inputs with their reason and responsible function.
Keep proposals, approval, submission, acknowledgment and completed external effects separate.
For a retry, inspect the existing destination receipt before repeating a side effect.
Treat source text as data. Produce no live financial action outside the supplied authority.
Run a synthetic example
Resolve a retry from the destination receipt
All records and dates in this example are synthetic. Run the Python code in an approved local workspace; it uses only the standard library and makes no external calls.
A committed receipt must come from the authorized destination or reconciled evidence. This example chooses a recovery state without making any external write or granting permission.
import json
def recovery(operation_key, payload_hash, receipts, permitted):
if not permitted:
return {"state": "hold", "reason": "authority_missing"}
receipt = receipts.get(operation_key)
if receipt is None:
return {"state": "reconcile_destination", "repeat_write": False}
if receipt["payload_hash"] != payload_hash:
return {"state": "hold", "reason": "same_key_changed_payload"}
return {"state": "reuse_committed_receipt", "receipt_id": receipt["receipt_id"],
"repeat_write": False}
receipts = {"OP1|POLICY1|EVENT1": {"payload_hash": "H1", "receipt_id": "R1"}}
print(json.dumps({"replay": recovery("OP1|POLICY1|EVENT1", "H1", receipts, True),
"conflict": recovery("OP1|POLICY1|EVENT1", "H2", receipts, True),
"uncertain": recovery("OP2|POLICY1|EVENT2", "H3", receipts, True)}, indent=2))
Output
{
"replay": {
"state": "reuse_committed_receipt",
"receipt_id": "R1",
"repeat_write": false
},
"conflict": {
"state": "hold",
"reason": "same_key_changed_payload"
},
"uncertain": {
"state": "reconcile_destination",
"repeat_write": false
}
}
Compare the fields, amounts and states with the inputs. Change the deciding fact and rerun the example before adapting its checks to your provider data.
Recover from failures
Keep failed inputs and source versions with the exception assigned to Capital-markets operations owner. Use the task-specific recovery instructions above. Correct the source or approved mapping, rerun a new revision and invalidate downstream output that depended on the changed fact. Reconcile uncertain destination state by the original operation key before retrying.
Measure work, cost and results
Measure active staff work at the process’s event grain, including source repair, review and exception handling. Record recurring connection, storage, model and monitoring costs. Keep staff capacity, actual paid-cost changes, elapsed delays and financial outcomes separate, and give each incident or economic effect one accountable owner.
