Proof: Live dashboard preflight returned an empty client response because an upstream control timeout rejected outside the server catch path and restarted operator-dashboard. The server now awaits API handlers, wraps control proxy failures, and returns structured JSON errors instead of crashing.
Assumptions: A timed-out control proxy should be observable as a dashboard control failure, not as process death. Returning 504/502 JSON is safer than treating the action as successful or hiding the upstream state.
Still fake: This does not make unanswered solver quote requests fill; it only makes the dashboard control surface truthful and non-crashing for failed or timed-out controls.
