## Objective
Verify an ongoing visit survives extreme structure changes (whole page/question deleted) without crashing or losing input.

## Preconditions
- See [[PRE-DF-mobile-assigned]]
- And the employee is on a specific page of an in-progress visit

## Steps
1. When the admin deletes a whole page/question and saves while the visit is ongoing

## Expected Result
- Then the ongoing visit remains safe on its old snapshot
- And the UI does not crash and does not lose entered input

## Source Traceability
- TSD: PK141
- Section: C3 - Mobile & History Impact
- Scenario: C3.2 - Ongoing visitation (edge case)
- Acceptance Criteria: PRD M.1 Scenario 2-4

## Evidence Required
- Screen recording of ongoing visit during an extreme portal-side deletion.

## Notes / Gaps
- No gap.
