First thing to check: the Bridge
Each desktop app starts a local engine sidecar (the Bridge) on a loopback port. Most “the app won’t do anything” reports are a Bridge that isn’t running yet or has stopped.
When an app reports the Bridge offline, the fix is the same: make sure the app finished starting, then use the in-app Retry (or Settings → Connection). The Bridge binds to loopback only; nothing listens on your network.
Conformance runs inside Post today, on Post’s
5101 Bridge, so conformance failures surface under Post below. The standalone Conform app on 5104 is in beta and not yet downloadable.

CLI
The CLI follows Unix conventions: exit0 on success, exit 1 on failure, so it slots straight into CI gates.
On macOS or Linux, if the
dotnet tool install can’t find a runtime, set DOTNET_ROOT to your dotnet install path before running pidgeon. For example /usr/local/share/dotnet on macOS, or /usr/share/dotnet (or $HOME/.dotnet for a manual install) on Linux, depending on how you installed .NET. The current public beta uses the .NET tool as its cross-platform install path; the separate signed ZIP in 0.1.0-beta.2 is a Windows artifact.
