Cristian Cezar Moisés 43d6306a06 GUI rework for source-only builds + CLI security fixes + packaging + cross-platform scaffolding
Fixes the "GUI functions don't work on GNU Guix" report and a batch of
adversarial-audit findings across the CLI, decoder, crypto and packaging.

GUI (gui/src/zupt_gui.py)
- Root cause of the broken GUI: every encryption path defaulted to the
  libzuptsdk "SDK v2" modes, which are absent from the source-only build and
  exit 1. Reworked Keys/Compress/Extract around the native modes with a
  build-aware PQ-mode selector: Hybrid (--pq, default), Full PQ (--pq-only),
  and SDK v2 only when the binary reports WITH_SDK support. Capability is
  detected from `version` ("Build:"/"KDF:" lines) with a `help` fallback.
- Extract/Verify gain a PQ private-key input with auto-detect (reads the
  archive via `info` to pick --pq vs --pq-only). Verify could not verify any
  PQ archive before (password field only).
- run_async now holds a LIST of in-flight (thread, worker) refs; DiskTab's two
  buttons previously shared one slot, so a second op GC'd the first QThread
  mid-run. About tab corrected (codec 2.60.4, PBKDF2 default, --pq-only, URL).

CLI (src/zupt_main.c)
- compress -p <archive> <files> swallowed the archive name as the password and
  truncated the first input file (silent data loss, exit 0). Added a
  data-loss guard: refuse to overwrite an existing non-.zupt file as the output
  archive unless -y/--force; plus a self-overwrite guard.
- compress <archive> <src> -p <pw> wrote an UNENCRYPTED archive (exit 0)
  because options after the first positional were treated as files. Now errors
  on a misplaced option (with a `--` escape for real dashed filenames).
- Removed duplicated dead --pq-box/--pq-sdk branches. version/banner/usage now
  state the build's real KDF (PBKDF2 on source-only) and repo URL; examples
  lead with native --pq / --pq-only.

Security (audit findings)
- vv_decoder.c: the two AVX2 fast-path token decoders read a 2-/3-byte match
  offset after only checking 1 byte remained -> heap over-read on a crafted
  archive. Added the `ip + off_bytes > ip_end` guard the tail path already had.
- zupt_crypto.c: wipe ML-KEM/X25519 secret-key buffers when hybrid decrypt
  init fails on key read (matches the pq-only path).
- zupt_format.c: bound attacker-controlled encryption_header_off before the
  (off_t)+7 arithmetic in the info enc_type reader (avoid signed-overflow UB).

Packaging (would fail source-only)
- debian/rules (staged into debian/zupt, installed vendored .so), aur/PKGBUILD,
  nix/flake.nix, homebrew (vendored .so + nonexistent AUDIT.md, stale /zupt
  URLs) now build source-only. opensuse spec %files ships the shell completions
  make install writes (rpmbuild no longer fails on unpackaged files);
  _service + debian/control point at the vaptvupt repo; KDF claim corrected.

Cross-platform GUI packaging (new)
- packaging/portable/: OS-agnostic GUI package (zupt_gui.py + .bat/.command/.sh
  launchers + README) that runs on Windows/macOS/Linux/BSD with Python+PySide6.
- .github/workflows/cross-platform.yml: builds real native binaries on
  windows-latest + macos-latest runners (CLI, PyInstaller GUI, Inno Setup
  installer, .dmg) and the portable zip, attaching them to the release on tag.
- packaging/windows/vaptvupt-gui.iss: Inno Setup installer script.

Validation: make check 16/16 (all distro-safe checks), GUI imports + command
contracts verified against the fixed CLI. test_help_consistency updated to
assert the truthful (build-aware) default KDF.

VaptVupt GUI

Desktop application for vaptvupt backup compression with ML-KEM-768 + X25519 post-quantum hybrid encryption.

Works on GNU/Linux, BSD, macOS, and Windows.

Install

tar xzf vaptvupt-gui.tar.gz && cd vaptvupt-gui
./vaptvupt-gui                      # auto-creates venv, installs PySide6
./install.sh --user              # adds right-click menu integration

Windows

Option A — Installer (recommended):

Download VaptVuptGUI-1.3.0-Setup.exe and run it. Installs to Program Files, adds Start Menu shortcut, desktop shortcut, right-click context menus, and .zupt file association. Includes uninstaller.

Option B — Build from source:

cd packaging\windows
build-windows.bat

Requires Python 3.9+, NSIS 3.x, and a compiled vaptvupt.exe.

Option C — Run directly:

pip install PySide6
python src\zupt_gui.py

macOS / BSD

pip3 install PySide6
python3 src/zupt_gui.py

AppImage (universal Linux)

chmod +x VaptVupt-GUI-1.3.0-x86_64.AppImage
./VaptVupt-GUI-1.3.0-x86_64.AppImage

Flatpak

flatpak-builder --install build packaging/flatpak/dev.zupt.gui.yml
flatpak run dev.zupt.gui

Features

Tab Function
Keys Generate ML-KEM-768 + X25519 hybrid keypairs
Compress All codecs, levels 1-9, dedup, solid, password, PQ keys
Extract Decrypt and extract .zupt archives
Verify Check block checksums, view archive metadata
Disk Full-disk backup and restore
About Version, cryptographic stack, credits

All tabs support drag-and-drop. Drop a .zupt file anywhere on the window to extract it. Drop any other file to compress it.

System Integration

Linux (Nemo / Cinnamon)

After ./install.sh --user:

  • Right-click any file: Compress with VaptVupt
  • Right-click .zupt file: Extract with VaptVupt
  • Double-click .zupt: opens in VaptVupt GUI

Windows (after installer)

  • Right-click any file: Compress with VaptVupt
  • Right-click any folder: Compress with VaptVupt
  • Double-click .zupt: opens in VaptVupt GUI
  • Right-click .zupt: Verify Integrity

The GUI calls the vaptvupt CLI binary — all cryptography runs in native C, not Python.

Packaging
