**Vulnerability:** Unvalidated inputs passed to `if()` statements can cause process crashes (`condition has length > 1`) or unexpected coercion vulnerabilities.
**Learning:** In R, optional boolean parameters that default to `NULL` should be validated using explicit runtime type validation (e.g., `if (!is.null(flag) && (!is.logical(flag) || length(flag) != 1 || is.na(flag)))`).
**Prevention:** Always implement explicit runtime type validation for optional boolean parameters.

πŸ“ Info: Stricter prompt regex changes retry behavior

With ^[0-9]+$ any digit string was accepted and returned, so entering e.g. "3" fell through to the confirm != 1 stop. Now ^[12]$ rejects it, looping up to three times before failing with the retry-exhaustion error instead. Behavior change is consistent across all three prompts and matches the PR intent.
