## Objective
Verify compound versioning bumps only on meaningful change while the Compound ID is stable.

## Preconditions
- See [[PRE-DF-compound-exists]]

## Steps
1. Save the compound without any change
2. In a separate run, make a meaningful change (item config, guideline, question structure/config), then save
3. In a separate run, change then revert to original, then save

## Expected Result
- Then a no-change save does not bump the version
- And a meaningful change bumps the compound version while the Compound ID stays the same
- And a change reverted to original does not bump the version
- And adding a new question creates a new Question ID

## Source Traceability
- TSD: PK141
- Section: C5 - Compound Modification
- Scenario: C5.2 - Compound versioning on meaningful change
- Acceptance Criteria: PRD C.18 Scenario 1-8

## Evidence Required
- Compound version + ID before/after each path.

## Notes / Gaps
- No gap.
