APPIMAGE_EXTRACT_AND_RUN=1 ./Lumen-0.20.1.AppImageVerification passed production typecheck/build, 1,699 unit tests across 109 files, 42 affected Chromium cases, all 66 packaged Windows native workflows (including the large AVIF round trip), and three linked-asset/directory/PDF capability workflows on each platform. Five focused shell workflows passed in the packaged Windows app and the actual AppImage, including Help/About, one-step duplicate/Undo, focused text handling and literal PNG/project reopening. Both platforms produced identical compiled files, and all 32 packaged application files matched their tested inputs. Each Windows package's 2,644 application payload files were extracted and compared byte for byte.
Linux runtime checks used WSL Ubuntu 26.04, Xvfb and AppImage extract-and-run. NSIS installation, portable bootstrapper execution and normal FUSE mounting were not exercised. Fullscreen coverage invokes the retained native menu role; it does not establish physical OS F11 dispatch. The complete earlier batch08 suite remains recorded against 0.20.0; the patch browser scope is the 42 affected cases above. Lumen remains a growing Photoshop-like editing foundation without full feature parity.
