A generic Qt-based filesystem watcher wrapping inotify. It emits signals for file creation, removal, and directory updates without polling, and is used by the daemon to monitor application directories. The component is self-contained and reusable in any Linux desktop tool needing asynchronous directory monitoring.

Encapsulates reversible deletion by moving files into a per-application .trash directory and later cleaning it up. The lifecycle is self-contained and can be extracted for file managers or desktop tools that need safe-delete semantics.

Parses ELF headers to determine architecture, static/dynamic linking, and binary size. It is used by the binfmt bypass launcher to select the correct interpreter and runtime. This is a focused, self-contained utility that could be reused by any tooling that needs to inspect ELF binaries.

Implements a command registry/factory for the ail-cli subcommands (integrate, unintegrate, would-integrate). It demonstrates a clean command-pattern design that makes extending the CLI with new verbs straightforward, and the factory/interfaces can be adapted for other C++ command-line tools.
