"""SDK-drift shims for LLM calls.

anthropic 1.0.0 changed Messages.create()'s signature (temperature= rejected), which
silently broke every Claude call on the Space for a morning — PM synthesis fell back to a
dumb confidence blend while the rest of the run reported success. Route all Claude calls
through claude_create() so a kwarg the installed SDK no longer accepts is dropped and
retried instead of failing the step.
