What I was looking for
What CreditWatch 1.0.0 could honestly claim on each platform.
What I found
CreditWatch 1.0.0 shipped macOS-only. The Windows and Linux credential stores were written and unit tested, and the Linux round trip passed headless. They stayed in the build. What changed was the README, the roadmap and the settings pane.
The reason: no human had run the installed binary on the other two. A claim is a promise to a user; unit tests are a promise to me.
The move
I claim only what a person has run end to end; the rest stays in the code, unannounced.
