What counts as evidence in the dotfiles repo, the full test-suite inventory with run commands, how to add and register a new test, and the known coverage gaps. Load when asked "how do I run the tests", "is there a test for X", "add a test", "what does this test failure mean", "is this change verified", or before claiming any change is done. Not for diagnosing a live broken machine (dotfiles-debugging-playbook), not for step-by-step proof recipes of symlinks/plugins/identity (dotfiles-verification-toolkit), and not for the change-gating rules themselves (dotfiles-change-control).
