# X_COVERAGE_BELOW_FLOOR

## Means

the unit suite covers less of the app than x.verify.json states

## Typical cause

Line or function coverage of the app's own source — every `.ts`/`.tsx` under `apps/` and `packages/`, a file no unit test loads counted at 0% — is under the `coverage` floor in `x.verify.json`. A test was deleted, or source landed without one. The finding names the measured and required numbers and the ten files that lose the most lines

## Fix

`x verify --only unit --json` — names the ten files losing the most lines; cover the worst with a test beside it
