X_README_EXAMPLE_UNSCANNED
Means
tsc did not run over the extracted fences
Typical cause
the fixture could not be written, or the compiler refused to start. tsc reports no semantic diagnostics at all once a program holds a syntax error, so a check that read this as "nothing wrong" would go green over every package at once
Fix
bun run scripts/readme-fences.ts --json — the finding carries the compiler's own output
