Filter: license

MIT — on the workspace allowlist.

Filter: types

TypeScript types via @types/react (community-maintained but canonical; ships in sync with each React major).

Filter: maintenance

Active. Maintained by Meta; v19 is the current stable major.

Filter: boundary-fit

Core UI package. React is required for the component library; appropriate for core-ui. No boundary rule violation.

Filter: shadow-check

React is already workspace-present in app packages. Same major version; no shadow.

Filter: eu-residency

Client-side rendering library; no vendor data transmission. n/a.

Filter: cve-scan

No advisories at adoption time.

Filter: named-consumer

core-ui renders all atomic-design components (Button, Input, Label, FormField) as React components.

Prompt: replaces

Nothing — React is already the UI framework in the workspace.

Prompt: migration-cost-out

Impossible: React is the foundational UI library for this workspace.

Prompt: alternatives-considered

React is workspace-locked as the UI framework. No alternative evaluated.
