What this module should change
You will be able to trace a design decision from source through tokens and component APIs to rendered behavior and verification.
Module guide
Four decisions to understand
Shared concepts
Design and code should agree on purpose, allowed choices, state, and outcomes even when tool constraints produce different APIs.
Create a mapping table for one component’s Figma properties, code props, DOM output, and test cases.
Tokens in production
Token pipelines transform governed decisions into platform formats while preserving references and modes.
Trace one semantic token through source, transformation, package, CSS or native output, and component use.
Documentation and examples
A useful example declares its assumptions, expected behavior, edge cases, and implementation status.
Add loading, error, localization, and keyboard examples to a happy-path story.
Testing and releases
Visual, interaction, accessibility, and contract tests protect different parts of the system promise.
Classify a recent regression by the missing test and the missing release signal.
Working principles
Parity is conceptual
Figma, React, SwiftUI, and Android views should share intent and supported states, not necessarily identical property surfaces.
Generated is not governed
Automation distributes decisions; review, versioning, ownership, and tests make them trustworthy.
The rendered output is the contract
Names and tokens matter because of the semantics, behavior, resilience, and appearance users finally receive.
