# TASK 5.2: Remove obsolete code paths and document final architecture

## Summary

Perform final cleanup after validation and leave a clear record of the new ownership boundaries.

## Dependencies

- TASK 5.1 complete

## Required Behavior

This task should:

- remove temporary compatibility code or development-only migration scaffolding no longer needed,
- ensure no misleading references remain to Laravel-owned persistence,
- document the final responsibility split across Keycloak, backend, and Front.

## Acceptance Criteria

- [ ] Obsolete compatibility code is removed
- [ ] Ownership boundaries are documented
- [ ] No active code paths still assume Laravel local persistence
- [ ] The final architecture is clear for future work

## Notes

- Favor a clean final state over preserving transitional complexity.
