+- WSL2 Ubuntu 24.04 independently cloned `0d03d00` into its Linux filesystem,
+  verified Node `22.22.2`, pnpm `10.33.4`, and passed frozen install with 999
+  packages. Pi staging passed for Linux x64 and arm64 (131 applicable packages,
+  six assets each), and electron-builder produced `linux-unpacked` plus the x64
+  AppImage. The full `package:linux` command then failed while building deb
+  targets because package metadata lacked `homepage`; this is a real release
+  packaging blocker. The verified origin URL is being added as the minimal fpm
+  metadata fix before rebuilding both Windows and Linux from one final commit.
