Motivation / context

• Fix the edge-counter logic in the clusterizer while preserving the existing fixed-window reconstruction behavior.

Key changes

• In TpcClusterizer.cc, FixedWindow handling in find_t_range and find_phi_range now:
  • sets the appropriate edge flags (tredge/tledge, sredge/sledge) when truncation occurs
  • increments counts.nedge only once per affected edge
  • uses edge guards (ttop_edge/ttbottom_edge, phitop_edge/phibottom_edge) to avoid double counting
• No functional changes were reported in calc_cluster_parameter; the TrkrClusterv5/TrkrClusterv6 selection remains unchanged.

Potential risk areas

• Reconstruction behavior changes at FixedWindow boundaries
• Downstream code that depends on ClusterCounters edge flags or counts.nedge
• Any implicit IO/format expectations tied to cluster counter semantics
• Performance impact appears likely minimal, but boundary bookkeeping should be checked in validation

Possible future improvements

• Add targeted regression tests for fixed-window boundary cases
• Validate edge counts against representative data samples
• Consider documenting the intended nedge/flag semantics more explicitly for future maintenance

📝 Walkthrough

Walkthrough

TpcClusterizer now marks which FixedWindow boundary was hit while counting truncated t and phi cluster ranges. The existing cluster-parameter selection branch is unchanged.
