HK-core SU3 4D kernel validation update

Release date: 2026-06-03
Commit: 94ec642d598ccf1a4f274ec77230e6e6b7e44ab9

This release marks the current 4D SU3 pure-gauge kernel as the active advanced HK-core path while keeping the December 2025 2D U1 result as the validated baseline.

Included

  • Cabibbo-Marinari SU2-subgroup heatbath plus overrelaxation is now the default SU3 update path (MILL_UPDATE=hb_or).
  • Plain Metropolis remains available only as an explicit comparison/diagnostic mode.
  • Effective-mass plateau extraction rejects negative mass windows as invalid physical plateaus.
  • Documentation and the manual runner now point to the SU3 master workflow.

Validation

  • Local cargo test --release -- --nocapture: 18/18 passed.
  • Included regression asset: beta5p5_seed944_heatbath_positive_plateau_regression.json.
  • Regression status: inconclusive, with ir_width=0 after the positive-mass plateau gate.

Scope

This is a kernel validation release. It is not a final Yang-Mills mass-gap claim.
