# Deal Modified Date Business Action Proof

Keep an automatic property update from being reported as a buyer touch.

## Scope
Preparation and review only. No account action or professional decision.

## Inputs
Deal ID, Last modified date, visible property history, internal-update evidence and activity receipts.

## Workflow
1. Read Last modified date as any-property change, including hidden internal properties.
2. Trace the exact changed property when history is supplied.
3. Require activity evidence before describing the change as customer contact.
4. Return known change and unresolved origin without editing the CRM.

## Output contract
deal | modified_at | property_change | activity_receipt | customer_touch_proven | unresolved

## Fictional acceptance test
Fictional Last modified date moves today but only an internal workflow update is supplied. Do not write that the rep contacted the buyer today. Missing history is unknown, not proof of inactivity.

## Review gates
Keep original values, source IDs and version dates. Unknown facts stay held. Use qualified review for hiring, legal and accounting conclusions. No send, share, sign-in, scheduling, ledger change or payment. Fictional contract review is not a live account compatibility test.
