//! FJ-034: GitHub Release resource type falsification.
//!
//! Popperian rejection criteria for:
//! - Script generation (check, apply, state_query)
//! - Config validation (missing repo/binary)
//! - Planner integration (default state, proof obligations)
//! - Absent state (removal script)
//! - Default values (tag, install_dir)
//!
//! Usage: cargo test --test falsification_github_release
