@ -85,6 +85,13 @@ Current hypothesis:
- the field needs better anisotropic behavior near sharp tapered contours
- it likely needs to distinguish motion along a stroke from motion across a stroke
What we just learned:
- the later `d9fa411` phase-field tuning pass was a real regression, not paranoia
- that pass strengthened the local edge penalty, added a spacing loss plus upper-spacing clamp, and made edge gating more aggressive
- on the pinned badge case, it removed internal linework and changed `2433 / 15876` output cells relative to the original good `phase-field` run
- reverting that tuning pass restores the original good badge result exactly; the fresh fixed run under `artifacts/phase-field-regression-fix-badge-126/` is byte-identical to the original `artifacts/phase-field-v1-recheck-badge-126/`
