5/5 Playwright scenarios passed · 230 vitest passed · type-check clean

Verified against a live core (127.0.0.1:18243) with two configured profiles (dev→[github, ast-grep], solo→[github]). Screenshots captured by switcher.spec.ts in execution order.

✅ Default state — no profile selected

Expected: Header shows “Profile: All servers”; zero-config default, no filter.

Observed: Label reads “All servers”; menu closed.

✅ Open switcher — profile list

Expected: Dropdown lists each configured profile with server membership + tool count; All-servers marked active.

Observed: “All servers” (active badge), “dev — 2 servers · 0 tools”, “solo — 1 server · 0 tools”.

✅ Select profile “dev”

Expected: PUT /api/v1/profiles/active persists; header label switches to the chosen profile.

Observed: Header label now reads “dev”.

✅ Active badge follows selection

Expected: Re-opening the menu shows the active badge + check on “dev”, not “All servers”.

Observed: “dev” carries the active badge/check.

✅ Clear back to All servers

Expected: Selecting “All servers” PUTs an empty slug; header returns to the zero-config default.

Observed: Header label back to “All servers”.
