Default is the single-engine chain exactly as before. With TAPIR_RECONCILE_BASE_MODEL set, the base engine and the primary run on the same WAV and a LOCAL model (config has already refused any non-local alias) reconciles them, at temperature 0 with a short reply -- the conditions its accuracy was measured under. The cloud fallback is unchanged and runs only when both local engines fail. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
