Linux desktop release build evidence

Current download: Ubuntu 24.04 x64 desktop 0.1.8. See final package checks and checksum. The current package includes the floating launcher, automatic local discovery, application search and hybrid relevance cleanup. Native compilation, 56 desktop tests, runtime provenance, loader checks and packaged CPU startup passed on Ubuntu 24.04 WSL. Native graphical interaction and other distributions remain unverified. The historical evidence below records preceding releases.

Source: a6bf091, desktop 0.1.3, Ubuntu 24.04 WSL x86-64, kernel 6.18.54.1-microsoft-standard-WSL2, two virtual CPU cores (AMD Ryzen 7 7800X3D).

Locked offline native Cargo release build with custom-protocol completed in 2m54s. The existing Windows-built production frontend was copied into the immutable Linux source snapshot; no separate Linux Node build is claimed. Verified normal Linux runtime files, decoder resources, licenses and extraction helper were prepared before compilation. Release extraction verification passed; normal Google runtime validation then passed 20 dependency records.

The executable is 35451968 bytes, SHA-256 11cefe0a8ee0f23c7c736d409992b8fe217207c77f934918ccfbf2c8ed1089c4. ldd resolved 130 library lines with no missing dependencies on this machine. The vendored reviewed GLib dependency emitted 34 known compiler warnings; this is not a strict Linux Clippy result. No GPU/model inference was executed here.

Raw build target: /home/karl/.cache/searchi-validation/desktop-target/release/searchi-desktop. Immutable source: /home/karl/.cache/searchi-validation/linux-desktop-a6bf091.

This proves native compilation and local loader dependency resolution, not native UI interaction, runtime resource discovery, clean-machine deployment, Wayland shortcut operation or broad Linux compatibility. Native graphical checks remain open.

Relocated startup

The release binary started outside the build tree in an owned bin/ directory with resources under lib/searchi/, as required by Tauri's product name. An isolated test profile reused a copied index and verified local model cache. The bundled Google process was observed with --device cpu --role query --threads 1; the desktop remained alive afterward. Owned test process groups were terminated. No user installation or system configuration was changed.

An owned Xvfb display plus LIBGL_ALWAYS_SOFTWARE=true, GALLIUM_DRIVER=llvmpipe and WebKit compositor/DMABUF-disable flags were used. Mesa's software setting is documented upstream. No pixel rendering, keyboard/preview interaction or actual foreground latency is asserted here. Initial fixture attempts failed because a filesystem-socket readiness check did not suit WSL and then because resources used the Cargo name instead of product name. Those were test-layout corrections; the final normal-discovery run passed. Raw ignored report: .searchi/qa/linux-desktop-startup-013.json, SHA-256 23bfebbd916e1d1e051efd58c5286b193b15014ebfcbaa621e6a5c650338bba5.

Debian package preparation

The official Tauri CLI 2.12.2 native tool was fetched from its upstream release and verified against GitHub's published SHA-256 35c7b50266256cb6d5f757608d7097a59a5faeb0c75879ee1f504652a9b6087e. Tauri generated a Debian package from the existing release binary. A first candidate accidentally included build-cache files from the validation snapshot and was never published. A fresh source snapshot now uses the existing verified resource stager, yielding 33 resource files instead of copying a CMake build tree. Linux staged .so files are excluded from Git like Windows DLLs.

The final Debian preview is published with v0.1.3: download and checksum. It is 103871912 bytes, SHA-256 2eb4252a16190353e7ad3074951d0c79ae03124b01bd3b048a72b6ad0efc0adb. Public unauthenticated download bytes were verified. Only the desktop executable was stripped; verified Google and extraction worker resources were preserved. XZ level-nine compression fits the existing upload limit without server changes.

Actual ELF requirements are GLIBC 2.39 and GLIBCXX 3.4.32; Debian dependencies declare libc6 (>= 2.39) and libstdc++6 (>= 13.2) alongside GTK/WebKit. This is an Ubuntu 24.04 x86-64 preview, not a general older-Linux package. Canonical resource staging used immutable source d0b8dbf; application source remains a6bf091. Later Rust fixes are not included in this package.

The final compressed package was extracted and started under an owned Xvfb/DBus session using the CPU/software flags above. Its bundled genuine Google query worker started with one CPU thread and the desktop remained alive afterward. Raw report: .searchi/qa/linux-deb-startup-013-stripped.json. This checks packaged startup and resource discovery, not interactive rendering, system installation, GPU operation or clean-machine compatibility.
