* claim: #1985 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01L15TLCjpXsQdp8ovC4ZacH * STEP export no longer hangs on a box with a screw hole (#1985) The export reads its own STEP text back, and meshing the read-back screw hole never finished. On a seam cylinder the boundary walk projected points to angles up to 5e7 rad apart and moved each by two turns at most, so the 11-point loop spanned millions of turns and the polyline closing it across the seam had 4.3 million points. Each projected parameter is now brought to within half a period of the point before it, whatever the gap. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01L15TLCjpXsQdp8ovC4ZacH * Second #1985 regression: the reporter's flanged enclosure The issue's reporter delta-debugged a second design whose STEP export hung on main: a flanged enclosure with two standoffs and no screw hole. It hangs without the get_mindiff change and reads back with 29 faces and the same volume with it. Both tests share the read-back checks.

"description": "Second reproduction for #1985, delta-debugged by the issue's reporter from the same enclosure with wall_thickness 3: a rounded box with a flange, an inner cut, a corner gusset and two standoffs, no screw hole. Its STEP export hung on main 675c8654 (but not on 0.14.0): the same boundary walk took a standoff's projected angles millions of turns apart.",
