## Objective
Verify an in-progress visitation continues on its original version when the form is modified mid-way.

## Preconditions
- See [[PRE-DF-mobile-assigned]]
- And the employee has started and is filling the form

## Steps
1. When the admin changes structure, logic, training material, or assignment name in the portal

## Expected Result
- Then the ongoing visitation keeps using the old version
- And validation and navigation flow do not change mid-process
- And the form does not reload to the new structure

## Source Traceability
- TSD: PK141
- Section: C3 - Mobile & History Impact
- Scenario: C3.2 - Ongoing visitation keeps old snapshot
- Acceptance Criteria: PRD M.1 Scenario 2-4, M.2 Scenario 3-6

## Evidence Required
- Ongoing visit unchanged after a mid-visit portal save.

## Notes / Gaps
- Extreme structure-change safety is covered by DFMOD-C3-EDGE-003.
