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.
Group the Cincinnati and GravographIS plugin projects in a Posts/
folder so new machine posts have one home. Project names, namespaces,
and the runtime Posts/ deploy target are unchanged; only relative
paths in the solution and project references move.
Benchmark jobs could only come from .nest files. A JSON manifest now lists
DXF files with quantities (plus sheet sizes, spacing, edge spacing, quadrant
and per-part allowRotation), imported through CadImporter. DXF paths resolve
relative to the manifest; sheet sizes are required from the manifest or
--sheet-sizes and are read in the DXFs' own units. Folder scans pick up
*.nest and *.manifest.json, and invalid manifests fail loudly.
BenchmarkRunner now runs (job x engine) solves concurrently, capped by
--parallel N (CLI default 3; --parallel 1 is sequential). Results are written
by index so report order is unchanged. Concurrent solves compete for cores,
so Time(ms) is only clean at --parallel 1; the run prints a note when N > 1.
Also fixes --output for manifest jobs, which tried to read the manifest as a
.nest to copy metadata from.

Add ChrFont, a reader for Gravograph .CHR engraving fonts, plus UI to
convert placed text into engraved geometry in the CAD converter.
The .CHR files are obfuscated with a single-byte XOR. Different
GravoStyle releases use different keys (0x2F in older versions, 0xCF in
the 7000 series, and others across the font library), so the key is
auto-detected from byte 1 of the file: the font name is ASCII stored as
UTF-16LE, so the high byte of its first character is 0x00 in plaintext
and the raw byte equals the key. This reads every font in a GravoStyle
install regardless of version, not just one hardcoded key.
UI: right-clicking a text item in EntityView raises TextConvertRequested;
CadConverterForm renders it via ChrFont with H/V alignment and adds the
result on an ENGRAVE layer.
Tests use Xunit.SkippableFact and a gitignored test-config.json so the
suite points at a local .CHR file without committing proprietary assets.

Splits that cross an interior cutout previously merged physically
disconnected strips into one drawing and drew cut lines through the hole.
The region boundary now spans full feature-edge extents (trimmed against
cutout polygons) and line entities are Liang-Barsky clipped, so multi-split
edges work. Arcs are properly clipped at region boundaries via iterative
split-at-intersection so circles that straddle a split contribute to both
sides. AssemblePieces groups a region's entities into connected closed
loops and nests holes by bbox-pre-check + vertex-in-polygon containment,
so one region can emit multiple drawings when a cutout fully spans it.

Add AutoTabMinSize and AutoTabMaxSize properties to enable automatic tab
assignment based on part size. Update CuttingParametersSerializer for
round-trip serialization and add tests.

DrawingSplitter now clips bend lines to each piece's region using
Liang-Barsky line clipping and offsets them to the new origin. Bend
properties (direction, angle, radius, note text) are preserved through
the entire split pipeline instead of being lost during re-import.
CadConverterForm applies the same origin offset to bends before passing
them to the splitter, and creates FileListItems directly from split
results to avoid re-detection overwriting the bend metadata.

Renamed OpenNest.Engine.Tests → OpenNest.Tests (directory, .csproj,
namespaces in all .cs files). Added OpenNest.IO project reference.
