+    A managed server that is running is stopped first (best-effort): the
+    server runs ``examples/openai_server.py`` from the checkout being
+    reset and imports the package being upgraded. Phases: stop server /
+    pip install -U / git update — CANCEL is honored between phases only,
+    so a started phase always completes. The pip package (into
+    FASTER_ENV) and the cloned checkout are refreshed independently: the
+    checkout only holds ``examples/openai_server.py`` (and the untracked
+    voices.json, which a hard reset leaves alone), so a failed phase is
+    warned about and reflected in the exit code without undoing the
+    other. Returns the exit code (130 when cancelled before a remaining
+    phase).
