Release 0.2.0: Code Quality and Remediation

Overview

This release focuses on code quality improvements, dead code removal, and comprehensive safety documentation.

Changes

Dead Code Cleanup

• Removed 11 unused modules:
  • benchmark, ci, explain, ratatui, defaults
  • security, compat, fuzzing, safe_regex, limits, ecma48
• Removed 9 #![allow(dead_code)] attributes from active modules

Tracing Removal

• Removed tracing and tracing-subscriber dependencies
• Replaced debug!() macros with conditional eprintln!() for verbose output

PTY Improvements

• Added impl Drop for Pty to ensure deterministic file descriptor cleanup

Safety Documentation

• Added comprehensive safety comments for all unsafe blocks in process.rs:
  • fork() - process duplication
  • ioctl(TIOCSCTTY) - terminal controlling
  • chdir() - working directory
  • __errno_location() - thread-local errno
  • write() - pipe write
  • _exit() / exit() - process termination
  • kill(pid, 0) - signal probe

Magic Number Constants

• Added constants in process.rs:
  • SIGTERM_TIMEOUT_MS = 500
  • POLL_INTERVAL_MS = 10
  • MAX_EINTR_RETRIES = 10
• Added test sleep constants for reliable testing

Scenario Validation Tests

• Added 28 integration tests covering validation of:
  • Invalid scenarios (empty name, zero dimensions, empty steps, invalid patterns)
  • Valid scenarios (all step types, all invariant types, complex commands)
  • JSON/YAML parsing

run_scenario Refactoring

• Split monolithic run_scenario() (365 lines) into 15 focused functions across 5 phases:
  • Phase 1: Initialization
  • Phase 2: Invariant Setup
  • Phase 3: Step Execution
  • Phase 4: Final Evaluation
  • Phase 5: Outcome Determination

Examples Updated

• All 7 examples updated to use current BTE format

CI Status

• Tests: 239 passed (201 unit + 38 integration)
• Clippy: 0 errors (103 warnings for dead code - intentional)
• Release binary: 3.5MB
