// Keyless assembled-browser coverage for the shipped FEEDBACK_ONLY default
// over the Web bundles and the real host wire. The scaffold mounts the
// shipped telemetry row in FEEDBACK_ONLY mode against this suite's own
// loopback mock collector, so the default release path is real: /feedback
// releases the session records through that event (exactly one OTLP request,
// carrying the drive prompt and the feedback text), the acknowledgement pins
// the feedback-gated disclosure sentence, and a second feedback releases only
// the records since the first handoff — the earlier prompt does not repeat.
