Add OpenNest.Reporting (net8.0, PDFsharp-MigraDoc 6.2.4) with a detached report snapshot and a PDF writer for an empty/demand-only job or a single plate layout: Letter portrait summary with vector part thumbnails and a landscape plate page with a vector sheet diagram, both with Page X of Y. - Snapshot uses reference identity for document-local R### IDs, recounts nested quantities from placements x copies with checked wide integers, excludes cutoffs from accounting, and retains no live domain objects. - Geometry keeps Cut/Display material paths, drops rapid/scribe/lead paths, preserves native arcs, holes and intentional tab gaps, and rejects malformed programs with plate/part identification. - Open contours and cutoffs are stroked per contour so PDFsharp cannot join a tab gap to the next contour. - Bundled DejaVu Sans via a custom resolver (including MigraDoc's error font); unsupported text fails with the field and code point. - Layouts beyond this slice (multiple plates, page overflow, labels that do not fit) fail with NotSupportedException before the destination is replaced; output is rendered to a temporary sibling and moved atomically.
