Module incremental_advanced_reuse 

Advanced AST node reuse strategies for incremental parsing. Incremental parsing implementation and helpers. Advanced tree reuse algorithms for incremental parsing

This module implements sophisticated AST node reuse strategies that go beyond simple value matching to achieve high node reuse rates even for complex edits.

Key Features

• Structural similarity analysis - Compare AST subtree patterns
• Position-aware reuse - Understand which nodes can be safely repositioned
• Content-based hashing - Fast comparison of subtree equivalence
• Incremental node mapping - Efficient lookup of reusable nodes
• Advanced validation - Ensure reused nodes maintain correctness

Performance Targets

• ≥85% node reuse for simple value edits
• ≥70% node reuse for structural modifications
• ≥50% node reuse for complex multi-edit scenarios
• <500µs processing for reuse analysis on typical documents
