A fail-closed Claude adapter
The adapter uses search-specific interface markers rather than scanning generic message containers. A provider UI change can temporarily stop capture, but it must not widen collection into the conversation.
Provider-native estimates
The current Anthropic endpoint does not return usable output token log probabilities. Open Queries therefore makes repeated structured-output calls to the named Claude model and reports candidate inclusion frequency with a Wilson 95% interval.
Claude candidates are never handed to GPT for ranking. The model, prompt version, sample count and estimator travel with the result.
Interpret the trace carefully
A surfaced query is direct interface evidence. An estimated fan-out is a model-specific reconstruction. Neither proves the provider's full internal retrieval process or population demand.
