Pattern: thinking-token use moved while the pass rate on the same probes stayed flat (1.00 before, 1.00 at onset). That is the signature of a serving-side change - an effort default or a routing change - rather than a different model behind the name, which usually moves accuracy too. Stated as a pattern, not a cause.
