📝 Walkthrough

Walkthrough

This PR enhances ElementExpressionHelper with improved robustness in expression and value parsing, adds two new public methods for tolerant enum matching and row-scoped helper creation, and provides comprehensive test coverage validating all existing and new behavior.

Changes

Graphics element expression helper robustness

Layer / File(s)	Summary
Expression/value handling improvements companion/lib/Graphics/ConvertGraphicsElements/Helper.ts	Core getter methods revise #getValue, getParsedString, getNumber, and getString to normalize missing values, NaN results, and parsing failures by always returning configured defaultValue instead of propagating empty strings or invalid states.
New public methods: tolerant enum and row helper companion/lib/Graphics/ConvertGraphicsElements/Helper.ts	getTolerantEnum performs case-insensitive enum matching on the first non-whitespace character; forRow normalizes unknown row objects into scoped ElementExpressionHelper instances that share the parser and variable tracking with the parent.
Test scaffolding and comprehensive coverage companion/test/Graphics/ConvertGraphicsElements/Helper.test.ts	Full vitest suite validates expression execution and variable ID tracking, all getter methods with edge cases (NaN, undefined, syntax errors, missing variables), row-scoped access behavior, element override precedence, and per-helper context isolation.

Poem

🎨 Helper methods bloom with grace,
Tolerant enums find their place,
NaN and undefined now tamed,
Row-scoped helpers—well-framed,
Tests ensure no edge case stays unnamed. ✨

❌ Failed checks (1 inconclusive)

Check name	Status	Explanation	Resolution
Title check	❓ Inconclusive	The title 'fix: test graphics ElementExpressionHelper' describes the main change—adding tests for the ElementExpressionHelper class—but uses 'fix:' which typically indicates a bug fix, while the changeset is primarily about adding test coverage for existing functionality.	Consider using 'test:' or 'tests:' prefix instead of 'fix:' to accurately reflect that this is test implementation rather than a bug fix (e.g., 'test: add graphics ElementExpressionHelper tests').
