GPT-5.6 Sol calibration feedback method for Kimi K3 is methodologically rigorous: focus on base rates, denominator/source definitions, and whether each time window is actually scorable, then provide a compact list of largest calibration or wording risks rather than broad stylistic feedback. This prioritizes the most impactful issues: an unscorable claim is useless regardless of how well it is written. Sol specific flags (E0-005 already true, E0-003 inconsistent, E1-060 unscorable) demonstrate the method in action.
