## Objective
Verify historical and task reports stay bound to the version used at submission, even after later modification.

## Preconditions
- See [[PRE-DF-submitted-report-exists]]

## Steps
1. When the admin modifies the form after submission
2. Open list history and detail history

## Expected Result
- Then history list and detail show assignment name, form ID, structure, and answers per the submission version
- And historical access is valid from all entry points named in the PRD
- And later database/label updates do not mutate historical answers

## Source Traceability
- TSD: PK141
- Section: C3 - History Impact
- Scenario: C3.3 - Historical reports reflect submission version
- Acceptance Criteria: PRD M.3 Scenario 1-5

## Evidence Required
- History payload before/after a post-submission modification.

## Notes / Gaps
- Cross-entry-point consistency is covered by DFMOD-C3-POS-005.
