# Reusable UI component authoring and review workbench

| Feature | Parent Epic | Delivery status | Status source | Owner | Approved for Solution |
|---|---|---|---|---|---|
| `3DARCH-FT-4` | [3DARCH-EP-1 — Engineering Platform, Quality, and Operability](../../3darch-ep-1.md) | `IN_BACKLOG` | `EXACT` | 3D Architecture Wizzard team | No |

## Description

Enable frontend developers and designers to create, demonstrate, accessibility-check, and test consistent interface components outside a product application.

## User or operator problem

Designers and frontend developers need to review component behavior and accessibility without mounting a complete product application.

## Expected value

Accelerates consistent component delivery and exposes interaction or accessibility defects earlier.

## Scope

Includes component generation, package export, Storybook documentation, accessibility checks, and headless story interactions.

### Exclusions

- End-user product behavior and solution or release authorization are outside these engineering Features.

## Acceptance outcomes

- [ ] A generator creates a component, story, and package export in the chosen atomic category.
- [ ] Storybook presents component documentation and accessibility tooling.
- [ ] Story interactions can run in a headless browser.
- [ ] The component library builds behind a stable package entry point.

## Dependencies

- [3DARCH-FT-1 — Reproducible monorepo development workspace](./3darch-ft-1.md)
- [3DARCH-FT-2 — Shared contracts and reusable interface foundations](./3darch-ft-2.md)

## Risks

- Storybook, accessibility tooling, and browser interaction tests can drift from the shipped component package.

## Human approval

Linas approved this Feature for documentation on 2026-09-02T10:40:43.220Z. It is **not Approved for Solution** and has no implementation approval.

- [Documentation decision](https://discord.com/channels/1518726359512387766/1543925247361814568/1544658325738885201)

## Delivery status evidence

The Feature was separately registered at `IN_BACKLOG` as an accepted catalogue boundary. This records backlog retention, not design or delivery progress.

- Event: Catalogue registration
- Actor and authority: Linas — Human project team member
- Reason: The Feature catalogue was accepted for governed documentation and retained in the backlog.
- [Status evidence](https://discord.com/channels/1518726359512387766/1543925247361814568/1544658325738885201)

## Architecture traceability

- Requirements: none derived.
- Readiness: Not started.

Architecture solution work must not begin until a separate human **Approved for Solution** decision is recorded.
