Module design_systems 

A2UI design-system bridge — component catalog, design-token import, and semantic-search embeddings for A2UI surfaces.

Migrated from flint-forge:

• flint-forge/crates/fdb-app/src/a2ui/ (domain types + the DESIGN.md parser) → types + design_md_parser, ported near-verbatim (pure Rust, no database dependency).
• flint-forge/migrations/0009_flint_a2ui_design_systems.sql (design system provenance columns + component_overrides table) → the Postgres migration under migrations/, and the SurrealDB schema in migrations/surrealdb/schema.surql, both consumed via store.
• flint-forge/crates/fdb-gateway/src/a2ui_embedder.rs (Postgres LISTEN/NOTIFY embedding worker) → embedder, re-architected around UAR’s EmbeddingBackend trait and DesignSystemStore instead of a Postgres-specific channel listener (see embedder’s module docs for the full rationale).

import is new UAR-side glue connecting the parser to the store, since flint-forge’s own “apply a parsed DESIGN.md” use case lives in its interface layer (out of scope for this migration).

See openspec/changes/a2ui-migrate-design-systems-embedder-from-flint-forge/ for the full audit of what was and wasn’t migrated, and why.

Modules

design_md_parser

DESIGN.md parser — 9-section Flint design specification format.

embedder

Component embedder — computes and stores semantic-search embeddings for the A2UI design-system component catalog.

import

Import pipeline — turns a parsed DesignMd document (or raw W3C tokens) into a persisted DesignSystem plus per-component ComponentOverrideRecords.

store

Storage for design systems, their base component catalog, and per-design-system component overrides.

types

Domain types for the UAR A2UI design-system bridge.
