NX Loom 0.26.0 — the suggestion lane

The promise from the very first release note, and the lane you picked first:
the tool can now propose edge flow — and only propose.

Suggest Arcs smooths a cross field over your sculpt, anchored to its
principal curvature wherever the surface is decisively bent. The field's
singular points are where poles belong; the separatrices flowing out of them
are the arcs a retopologist would draw — and they appear as ghosts,
visibly not part of your document, with Accept and Discard beside them.

Accepted proposals run through the exact same machinery as a hand-drawn
stroke — snapping, crossing junctions, seam reflection — and become ordinary
arcs with no memory of where they came from. Manual stays primary, per the
spec that froze it: nothing runs unprompted, and a surface whose curvature
pins nothing down yields no proposals instead of noise.

The field keeps honest company: on a cylinder it runs along axis and rings
with zero invented poles; on a sphere it carries exactly the eight
quarter-turns of index the topology owes; on a flat sheet it stays silent.
All under test. Big sculpts are decimated to a solving proxy automatically.

405 headless checks + 16 GUI checks; the 122-layout sweep is clean.
