## Objective
Verify invalid availability periods are blocked at save.

## Preconditions
- See [[PRE-DF-cp-editing-form]]

## Steps
1. Set an end date before the current date, or otherwise an invalid period, then attempt to save

## Expected Result
- Then the system blocks the save with a validation message

## Source Traceability
- TSD: PK141
- Section: C6 - Availability Modification
- Scenario: C6.1 - Availability validation
- Acceptance Criteria: PRD C.22 Scenario 1-5

## Evidence Required
- Screenshot of blocked save with invalid period.

## Notes / Gaps
- Testing Concern TC-05 (High): exact rollover behavior at 23:59 → 00:00 (device date boundary) pending confirmation.
