 ## Validation
 
 The integration driver installs pinned collection dependencies, runs syntax
-checking and ansible-lint, and verifies the default release and idempotence. It
-also covers a missing binary, a caller-supplied Go executable with dependency
-management disabled, metadata drift without a build, selection of the previous
-release, restoration of the default release, and platform failures before
-application state is created. The suite mutates only
+checking and ansible-lint, and covers default smoke use with clean repeated
+convergence. It also verifies an explicitly selected Seriatim release and
+combines missing-binary recovery with a caller-supplied Go executable while
+dependency management is disabled. The suite mutates only
 `/usr/local/src/seriatim`, `/usr/local/bin/seriatim`, and paths inside its
-private temporary directory, and leaves the default release installed:
+private temporary directory, and restores the default deployment during
+cleanup:
