gudusoft.gsqlparser.ir.semantic.diff (General SQL Parser Java Library Core 4.2.9 API)

Class Summary
Class	Description
CanonicalLineageEdge	One canonical-form lineage edge used for cross-engine comparison.
CanonicalLineageModel	Common comparison form for both Semantic IR and dlineage.
Divergence	One classified divergence between IR and dlineage projections.
DivergenceJsonExporter	Hand-rolled deterministic JSON exporter for `DivergenceReport`, in the same style as `gudusoft.gsqlparser.ir.semantic.export.SemanticIRJsonExporter`.
DivergenceReport	Result of comparing two `CanonicalLineageModel` projections of the same SQL.
DivergenceReporter	Pure comparison: two `CanonicalLineageModel`s in, one `DivergenceReport` out.
DlineageXmlProjector	Project the existing `DataFlowAnalyzer` XML output into the same canonical form as the Semantic IR projector.
Lineage2Projector	Project a lineage2 contract JSON document (lineage2-contract.md §2, v0.9) into the `CanonicalLineageModel` comparison form shared with `SemanticIRProjector` and `DlineageXmlProjector` (US-010).
ProjectorResult	Pure-function return type for both projectors.
SemanticIRProjector	Project a `SemanticProgram` into a `CanonicalLineageModel`.

Enum Summary
Enum	Description
DivergenceClass	Slice-7 divergence classes; the in-scope subset of the seven classes defined in the unified-roadmap §10.4.
DlineageXmlProjector.FanoutPolicy	Policy for `DlineageXmlProjector.resolveBaseSources(String, Document, FanoutPolicy)`.
EdgeRole	Classification of a `CanonicalLineageEdge`.
ProjectorResult.UnsupportedReason

Package gudusoft.gsqlparser.ir.semantic.diff Description

Projection and parity utilities used to compare Semantic IR with lineage engines.

API status: internal. These public types support GSP development and verification. They are not part of Join Analysis Consumption Profile v1 and may evolve with the parity harness.
