Could you build this?

Partial A basic offline SVG-based UML editor in vanilla JavaScript is vibe-codeable. Full UML 2.5.1 compliance with 71 validation rules and 449 constraints requires deep knowledge of the specification.

What it would actually take: The stack is vanilla ES modules with SVG rendering, a model and metamodel layer, and a rule engine that encodes OCL-like constraints from the UML spec. The hard part is faithfully implementing the spec's well-formedness rules and constraint semantics. That needs someone who has read UML 2.5.1 closely and can test validation against known-correct models.
