Nabu + Nisaba

""" Incremental update system for nabu. Enables efficient file-level updates using stable_id for change detection. Achieves 3-5x speedup by updating only changed frames (20-30%) instead of re-parsing entire codebase. Components: - diff_calculator: Compute frame differences using stable_id - db_mutator: Execute database updates (delete/insert/update) - relationship_repairer: Repair CALLS and IMPORTS edges - metrics: Track update performance and stability - updater: Orchestrator for incremental update workflow Usage: from nabu.incremental import IncrementalUpdater updater = IncrementalUpdater(db_path="nabu.kuzu") result = updater.update_file("src/foo.py") print(f"Updated {result.frames_added + result.frames_deleted} frames") print(f"Preserved {result.frames_stable} frames ({result.stability_percentage:.1f}%)") """ from nabu.incremental.diff_calculator import FrameDiff, StableDiffCalculator from nabu.incremental.db_mutator import DatabaseMutator, DeleteResult, InsertResult, InsertEdgeResult from nabu.incremental.relationship_repairer import RelationshipRepairer, RepairResult from nabu.incremental.metrics import UpdateMetricsCollector, UpdateMetric from nabu.incremental.updater import IncrementalUpdater, UpdateResult __all__ = [ 'FrameDiff', 'StableDiffCalculator', 'DatabaseMutator', 'DeleteResult', 'InsertResult', 'InsertEdgeResult', 'RelationshipRepairer', 'RepairResult', 'IncrementalUpdater', 'UpdateResult', 'UpdateMetricsCollector', 'UpdateMetric', ]
