- Primary objective: This report determines what the future component library should be built upon. It does not define production APIs, names, markup, tokens, or components. Its purpose is to reduce the chance of creating architectural commitments that later prevent visual redesign, accessibility, replacement, or cross-product reuse. The central question is not whether Web Components work. They do. The central question is where custom elements, native HTML, CSS, JavaScript behavior, design tokens, and composition e…
- Primary claims/evidence: A native element consistently cannot meet core product requirements, while a custom implementation demonstrates equivalent accessibility and lower total complexity across supported contexts.
- Methodology: Custom elements do not inherently make an interface redesignable. A poorly modeled custom element can be more rigid than ordinary HTML. Redesignability comes from durable content models, presentation-neutral DOM order, parent-owned composition, contextual tokens, low-specificity CSS, and controlled escape hatches.
- Limitations/known uncertainties: Native HTML limits: - inconsistent or constrained styling, - missing complex patterns, - limited component lifecycle, - historical browser inconsistencies, - no domain-specific semantic vocabulary. Remaining Unknowns: The following cannot be resolved confidently without project-specific evidence: 1. Which exact domain composites are stable enough to enter the shared library. 2. How radical the desired visual systems will be in structural terms. 3. Which…

Challenge and confidence decay
The source was challenged for construct validity, independent replication, boundary conditions, transfer, and comparative baselines. Confidence should decay when the source lacks a dated replication, when its technology or target population changes, or when later artifacts report contradictory findings. Revalidation is recommended before treating context-bound recommendations as universal.
