# Engineering Platform, Quality, and Operability

| Epic | Delivery status | Status source | Owner | Approved for Solution |
|---|---|---|---|---|
| `3DARCH-EP-1` | `IN_BACKLOG` | `DERIVED` | 3D Architecture Wizzard team | No |

## Goal

Provide a dependable engineering foundation for building, testing, documenting, packaging, deploying, and operating the complete 3D platform and its shared capabilities.

## Benefit

Teams can evolve the platform safely and consistently while preserving the quality and operability of the complete experience.

## Problem or opportunity

The platform spans browser applications, real-time services, AI-assisted generation, shared contracts, persistence, and delivery infrastructure that must evolve without destabilizing user journeys.

## Constraints

- Only materially implemented legacy behavior is included; planned-only capabilities remain outside the approved catalogue.

## Features

- [3DARCH-FT-1 — Reproducible monorepo development workspace](./3darch-ep-1/features/3darch-ft-1.md)
- [3DARCH-FT-2 — Shared contracts and reusable interface foundations](./3darch-ep-1/features/3darch-ft-2.md)
- [3DARCH-FT-3 — Automated multi-layer quality verification](./3darch-ep-1/features/3darch-ft-3.md)
- [3DARCH-FT-4 — Reusable UI component authoring and review workbench](./3darch-ep-1/features/3darch-ft-4.md)
- [3DARCH-FT-5 — Versioned engineering knowledge hub](./3darch-ep-1/features/3darch-ft-5.md)
- [3DARCH-FT-6 — Repeatable database schema lifecycle](./3darch-ep-1/features/3darch-ft-6.md)
- [3DARCH-FT-7 — Integrated local runtime with persistence and health checks](./3darch-ep-1/features/3darch-ft-7.md)
- [3DARCH-FT-8 — Package, deploy, and health-check workplace services](./3darch-ep-1/features/3darch-ft-8.md)

These Features are approved for documentation only. Each remains outside Architecture solution work until a separate human **Approved for Solution** decision is recorded.
