# X_REFERENCE_APP_REGRESSED

## Means

a step of a tracked app's own gate that was passing now fails — or the gate produced no step table at all

## Typical cause

a framework change broke `examples/dummy` or `dummy/social-media-clone`, and the step is not one of that app's pinned entries

## Fix

`cd <app> && bun run ../../packages/cli/src/bin.ts verify` — the `fix` line names the app
