# Showcase sources and permitted claims

These are engineering examples, not customer work, reviews or testimonials. Files were copied unchanged from recorded local evidence on 2026-10-08. `manifest.json` gives original records, parameters, dimensions, dated checks and SHA-256 for every copied file. Reference outputs and their previews are thresholded, pixel-traced and scaled transformations, not the upstream source SVGs.

## Heart JPG and gear

Inputs and downloaded SVG/DXF outputs were recorded on 2026-10-07 in Playwright Chromium 151.0.7922.34. Both use threshold 128, invert off, no denoise and no node reduction, width 100 mm. Heart: 100×93.75 mm, one outer contour, no holes. Gear: 100×100 mm, one outer contour and three holes. Previews are recorded renders of the downloaded SVG. These two examples have no recorded LightBurn or Cricut import check.

## Calibration and actual software screenshots

`calibration-100x70.png`, `.svg` and `.dxf` are a project-created asymmetric engineering fixture, constructed by `scripts/import-calibration.ts`, with no third-party artwork/source URL. No separate asset license declaration is recorded for this fixture; no external license is invented here. The PNG is 100×70 pixels; exported geometry is 100×70 mm, including a 50×40 mm hole, 10×10 mm island and 20×15 mm bottom-right notch. The script directly constructs binary geometry; it does not record a browser workbench conversion. The generator has no exact timestamp in its original manifest.

`lightburn-svg-import.png` and `lightburn-dxf-import.png` are unchanged screenshots from the recorded 2026-10-07 import check: LightBurn 2.1.04 Core, macOS 26.6.2, built-in No Machine profile. Each format was imported into a new document; the toolbar shows 100.000×70.000 mm and three objects. Hole/island sizes were visually checked against the grid. Screenshots contain the LightBurn interface, owned by its respective rights holder, and serve only as engineering evidence. No separate screenshot license is recorded, and credit does not imply endorsement. Official installer source recorded during that check: https://release.lightburnsoftware.com/LightBurn/Release/LightBurn-v2.1.04/LightBurn.V2.1.04.dmg

No machine was connected or operated. This one fixture does not demonstrate arbitrary-file compatibility, machining accuracy or Cricut support. Historical records remain unchanged; any earlier real-user cohort wording in them does not reinstate the removed release gate. Keep all untested checks visible, including self-intersection.
