Real-World Example: Dashboard ViewerFrame
Scenario: A monitoring dashboard with 5 widgets, updating every 10 seconds.
Poor approach: Reload entire dashboard → all graphs re-render, user loses zoom settings.
Best approach: viewerframe mode refresh best

- Keep scroll position.
- Retain focus.
- Maintain expanded/collapsed states of UI elements.
Consistency & correctness
- Versioning: include incremental version or sequence IDs with each payload/patch; reject out-of-order updates.
- Atomic updates: apply multi-part updates as a transaction; show staged state until all parts succeed, or rollback on failure.
- Idempotency: make patches idempotent where possible to allow retries.
- Conflict resolution: prefer last-writer-wins or merge strategies depending on domain; surface irreconcilable conflicts to a reconciliation routine.
Security & data integrity
- Validate payload signatures or checksums where available.
- Sanitize incoming data before rendering.
- Enforce least privilege for refresh endpoints and rate-limit clients.
