//! Regression test for bug #24 (exit-code half): a scan with per-file read failures
//! but a successful index update must exit 0 — the read failure is non-fatal because
//! the index WAS updated. Previously the scan exited 2 whenever `read_failed > 0`,
//! masking an otherwise-successful run.
//!
//! Unix-only: simulates a read failure via `chmod 000`, which has no Windows analogue.
