//! Edge case tests for the `case_sensitive::` parameter.
//!
//! ## Source
//!
//! - Spec: `tests/docs/cli/param/02_case_sensitive.md`
//!
//! ## Coverage
//!
//! - EC-1: Value 0 uses case-insensitive matching
//! - EC-2: Value 1 enables case-sensitive matching
//! - EC-3: String "true" rejected
//! - EC-4: Omitted defaults to 0 (case-insensitive)
//! - EC-5: `case_sensitive::1` misses case-different matches
//! - EC-6: `case_sensitive::0` finds case-different matches
