v0.3.0

[0.3.0] - 2026-03-18

Added

• Stochastic MCTS-based Scanner: New informed search strategy using Monte Carlo Tree Search (MCTS) to prioritize high-value garbage branches.
• Parallelization: Bounded worker pool using asyncio.to_thread for concurrent filesystem exploration.
• Incremental Metadata Propagation: Push-based upward metadata updates for $O(1)$ root snapshots and improved wide-tree performance.
• Documentation Suite: Comprehensive docs/ directory with MkDocs/Material theme integration.
• CI/CD: Automated testing and PyPI publication workflows via GitHub Actions.
• Real-time Metrics: Scan speed indicator (MB/s) and summary statistics in the TUI.
• Graceful Interruption: Robust Ctrl+C handling in the scanning phase.
• Sentinel Verification: Content-based verification for garbage signatures (e.g., checking for package.json in node_modules).

Changed

• Refactored Scanner to an async-first model.
• Optimized signature matching with name-based fast-paths and caching.
• Enhanced GCTrail binary schema to store top subdirectories for informed selection.

Fixed

• Performance bottlenecks in wide directory tree traversals.
• Quadratic complexity in MCTS node selection.
• Redundant signature matching across iterations.
