- fail enabled settings-profile create and launch flows when hook preparation is still unusable
- refresh stale shared hook binaries without rewriting unchanged installs or failing benign races
- add rollback and regression coverage for disabled, stale, invalid, copy, import, and launch paths
- verify the hook binary before migrating global WebSearch hook state
- centralize migration-marker helpers in hook-installer exports
- expand regression coverage for existing-hook, disabled, invalid-name, and failed-install paths
- ensure profile hook injection installs the transformer binary before writing the command
- keep migration marker cleanup in the installer to avoid a circular import
- add a regression test for isolated CCS_HOME settings profiles
