New post-processor plugin OpenNest.Posts.CincinnatiCIFiber for the CI Fiber laser family (nLight CLX / Beckhoff TF5200 / Precitec ProCutter, e.g. the CI Fiber 4020 8kW). Named by machine family, not table size. Emits the machine program contract of the Cincinnati-supplied sample NC (12992-4SS_NEST.nc): V.E.* header, restart jump, per-part V.E.R4 blocks, per-contour N labels with V.E.R3, skippable /L macro lines (L0/L2+G41 interior, L4+G42 exterior, L6 cut-on, ZHSOFF cut-end), G162 incremental arc I/J, trimmed 3-decimal spaceless coordinates, CRLF, M50/M30/%. Contour classification (interior vs exterior) derives from the material side of the closed cut path, not hardcoded winding. SubProgramCall holes are flattened to sheet coordinates (rotation-safe). Arc lead-ins are rejected per TF5200 13.2.4.1 (first motion block after G41/G42 selection must be linear). Table envelope (default 160.25 x 81.25 in) validated. Tests: structure golden on a square-with-hole nest, rotated-hole flatten, coordinate format, arc-lead-in rejection, table validation, suppressed/ scribe skipping, plus a SkippableFact regression against the real sample NC (109 parts, 2071 contours, L2=1962, L4=109, perimeter vertices match within 0.001). Fixtures configure through OpenNest.Tests/test-config.json and the regression skips when absent.
