What's here

The whole Qt-plugin mechanism, in two parts:

Artifact	Side	Sources	Links
logos_module_loader_qt (static lib)	parent	qt_plugin_format_loader.{h,cpp}	boost::dll, spdlog, the loader contract. Qt-free / SDK-free. Linked into logos_core.
logos_host_qt (binary)	child	host/ (logos_host, command_line_parser, module_initializer, qt_app, token_source)	the full SDK stack + Qt + CLI11 + logos-module. Bundled by frontends.

The parent (QtPluginFormatLoader) only resolves the logos_host_qt binary path and builds its CLI arguments (--name, --path, --instance-persistence-path, --transport-set) — it is deliberately light so logos_core doesn't pull Qt or the SDK just to know how to launch a Qt-plugin module.

The child (logos_host_qt) loads a single Qt-plugin module in its own process: it reads its auth token from the channel its container designated via --token-source (default stdin — so the host depends on no container package), then loads the plugin and brings up LogosAPI.

A logos_host → logos_host_qt compatibility symlink is installed so frontends keep working with either name.

Build & test

nix build .#logos-module-loader-qt              # lib + header + host binary
nix build .#checks.aarch64-linux.tests -L       # run the loader + token-source tests
