We review messages in sequence and prioritize reproducible issues that affect calculator correctness, accessibility, or user safety.
Where appropriate, we may convert confirmed issues into product updates covering formula behavior, validation messaging, or guide-page explanations.
Reported issues are categorized as correctness, usability, accessibility, content-quality, or policy-interpretation.
When reports include reproducible inputs and expected behavior, remediation is significantly faster.
