 - **src/history.py:** Implements the core `HistoryManager` and `UISnapshot` logic for the non-provider undo/redo system. Manages state stacks with a fixed capacity and provides jumping capabilities.
 
 - **src/paths.py:** Centralized module for path resolution.
-- **tree-sitter / AST Parsing:** For deterministic AST parsing and automated generation of curated "Skeleton Views" and "Targeted Views" (extracting specific functions and their dependencies). Features an integrated AST cache with mtime-based invalidation to minimize re-parsing overhead. Supplemented by `SummaryCache` which provides persistent, hash-based (SHA256) caching with LRU eviction for AI-generated file summaries.

 - **pydantic / dataclasses:** For defining strict state schemas (Tracks, Tickets) used in linear orchestration.
 - **tomli-w:** For writing TOML configuration files.
 - **tomllib:** For native TOML parsing (Python 3.11+).
