External pricing functions fail over instead of echoing your price
An external pricing function that answers with no usable price or confidence now counts as a failed attempt and falls through to the fallback chain, instead of reporting your own price back as a computed answer.
Previously, an external pricing function that responded successfully but without a usable price (for example, an error body) was reported as "no change" at a confident score, using the current price you sent in. That substitution is gone.
- A missing price or confidence is now treated as a failed attempt, so the fallback chain and circuit breaker take over.
- You no longer receive your own current price back as if it had been computed.
