A layered image editor for Linux and Omarchy, ported from Compositor (github.com/robbietilton/Compositor), whose Swift source is its specification. It reads and writes Compositor's .comp projects. Packages for Ubuntu, Fedora and Arch come from the release workflow; scripts/install/ holds one install script per distribution family, and flake.nix serves NixOS.

"""Mutation runner for OmaPhoto. Run from the repository root.

mutate.py FILE --delete [--from N --to M] [--targets T1,T2] delete each statement line in turn

Verdicts: 'caught' means the mutant built and a test that really ran failed; 'UNBUILDABLE' means the

compiler rejected it, which proves nothing; 'SURVIVED' means every test passed. Anything else (Docker

not starting, a missing test executable, a failing baseline) stops the run with an error.
