Closed-Loop Development — Continuous Sync Between Frontend and Backend

Traditional handoffs are one-shot: a designer or AI tool generates a frontend, throws it over the wall, and hopes the backend team can figure out what endpoints to build. That breaks after the first iteration. AppHandoff replaces one-shot handoffs with a closed-loop cycle that keeps frontend and backend continuously synchronized.

Each loop iteration follows a predictable sequence. The scanner detects mismatches between frontend API calls and backend endpoints. Tickets are generated with implementation details. Agents or developers resolve tickets through pull requests. The scanner re-runs and confirms the mismatch is gone.

The closed loop runs automatically on every push to either repository. Teams see their mismatch count decrease over time instead of discovering integration failures during QA or after deployment.
