Module semantic_diff 

Semantic diff — enriches object-level diffs with structural context.

Takes a CodeDiffResult (which nodes changed) and produces a SemanticDiff that adds:

• Impact analysis: which edges are affected by each change
• Containment context: parent/child relationships for changed nodes
• Change classification: API-breaking vs internal, signature vs body
• Human-readable summary: grouped by file/module for review

Structs

AffectedEdge

An edge affected by the diff (e.g., a call to a removed function).

DiffStats

Summary statistics for a semantic diff.

SemanticDiff

A semantically enriched diff.

SemanticDiffEntry

A single enriched diff entry.

Enums

AffectedReason

Why an edge is affected.

ChangeClassification

Classification of a code change.

Functions

format_semantic_diff

Format a semantic diff as a human-readable review summary.

semantic_diff

Compute a semantic diff from an object-level diff and the CodeGraph state.
