Conduct the repository's TESTS_MANUAL.md plan as a guided manual test — the USER runs every command and GUI action while Claude presents one step at a time, evaluates reported results, proposes (never applies unasked) fixes, and keeps the protocol file. Use when the user wants to test by hand, run commands themselves, do a guided walkthrough or acceptance session, or verify the app manually — with optional scope arguments.
