Recommended Action

Circular Dependencies

Expressions don't create update loops.

Use one shared calculation where practical.

JavaScript Number Behavior

Decimal calculations use appropriate precision.

Round results when fixed precision is required.

                    Math.round(calculated.value * 100) / 100

Names and Import IDs

Element names, URIs, import IDs, and functions do not conflict.

Use descriptive names and version import IDs.
