- Normalize IF/Abs/Pow/etc. to lowercase before evaluation so AI-generated or manually typed uppercase function names no longer cause "Function not found" errors - Add NormalizeAndValidate() which normalizes then does a parse-only check on save — invalid formulas are rejected with a clear error before storing - Update AI system prompt to list all functions in lowercase and explicitly call out case-sensitivity; add if() to the supported function list - Add collapsible NCalc quick-reference panel in the formula editor showing all operators, functions (lowercase), built-in variables, and an example Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
