Detailed Description

Runs a segment-level GNN on reconstructed muon segments to classify segment-pair edges as "good" or "background".

The tool reads a xAOD::MuonSegmentContainer and builds a graph where:

• Nodes are muon segments, each with 10 features:
  • Position and direction (6 floats)
  • Chamber index, layer count, sector, and segment multiplicity (4 floats)
• Edges connect all segment pairs within an angular threshold (cos(angle) >= cos(MaxDeltaThetaDeg)) and sector distance, with 7 features:
  • Spatial displacement (3 floats: dx, dy, dz)
  • Distance magnitude (1 float)
  • Angle (dot product, 1 float)
  • Chamber and sector match flags (2 flags)

The tool then runs an ONNX model (typically a GIN or GCN variant) to produce a logit or probability for each edge, enabling downstream algorithms to filter low-quality segment associations and improve reconstruction efficiency.

Key difference from GraphBucketFilterTool: operates at segment (edge) level rather than bucket (node) level, and the interface uses discrete graph structures (SegmentEdgeGraph) rather than tensors for input/output.

Note: runGraphInference() is not supported by this tool; use SegmentEdgeInferenceAlg and the ISegmentEdgeClassifierTool methods instead.
