mathiasandClaude Sonnet 5.5 7891675393 test(llm): a temperature option; zero is sent as zero, not 'unset' (red)
The reconciler was measured at temperature 0 but the client hardcodes 0.2. Zero must
be sent explicitly, and the default must not change for existing callers.

Red: WithTemperature is undefined.
