**Issue Evaluation** Category: `bug` | Status: **Confirmed** This is a valid race condition bug in the add-instance modal. When async requests for credentials, regions, or instances complete out of order, stale responses overwrite the current catalog state — causing the modal to display data from the wrong cloud account/region. **Root Cause:** The async effects only cancel zero-delay timers but do not invalidate in-flight HTTP requests. A slower response from a previous selection can arrive after a faster one from the current selection, corrupting the UI state. **Impact:** Users may see incorrect regions or instances belonging to a different cloud account/region, and the shared loading flag can be prematurely cleared by an obsolete response. **Severity:** Medium — affects data correctness in the multi-cloud onboarding flow but does not cause data loss or corruption on the server side. **Suggested approach:** Use an abort controller or request-ID pattern to ensure only the latest request per dependency set can mutate state. Each async effect should check a stale flag before committing its response. An automated fix proposal can be generated.
