# Kiduna Studio — Preliminary Engineering Handoff

**Package date:** July 19, 2026  
**Design-program position:** after Gate 2B.1, before Gate 2B.2  
**Recorded Design Lab commit:** `e729fec`  
**Live review surface:** https://www.kiduna.design/?persona=david  
**GitHub review:** https://github.com/uncle-psy/kiduna-studio-prototype/pull/10

This kit gives production engineering a coherent, source-backed UI/UX model for planning and reversible foundational work. It combines the five Outside the Studio journeys, the accepted Gate 1 one-center experiment, and the three Gate 2B.1 primary Realm scenes.

It is deliberately preliminary. It is not the final Gate 7 handoff, does not begin Gate 2B.2, and does not turn design fixtures or working terminology into canonical product truth.

## Begin here

1. Read `START_HERE.md`.
2. Walk the static review site in `prototype-site-static/` or use the live URL.
3. Read `DESIGN_INDEX.md` alongside the scenes.
4. Read `PRELIMINARY_ENGINEERING_PLAN.md`, `PRIORITIZED_USER_STORIES.md`, and `ACCEPTANCE_MATRIX.md`.
5. Read `OPEN_DECISIONS_AND_RISKS.md` before estimating or committing to architecture.
6. Use `AGENTS.md` with Codex or `CLAUDE.md` with Claude Code.

## Package map

- `prototype-site-static/` — complete generated static site, including the five Outside pages and both Inside prototype routes.
- `outside-studio-original-html/` — the original five Outside journey HTML packages, preserved separately.
- `scene-shortcuts/` — direct local launch pages for each of the six Inside designs.
- `source/design-lab/` — source for the combined Design Lab at commit `e729fec`.
- `source/gate-1/` — accepted Gate 1 review source and audit.
- `source/gate-2b1/` — Gate 2B.1 primary-scene source and audit.
- `program-definition/` — design-system governance, taxonomy, contracts, matrices, evidence, decisions, and open questions.

## Boundary

Engineering may plan foundations that are reversible and independently useful: shared visual tokens, accessibility baselines, interaction primitives, fixture isolation, test harnesses, and contract seams. Engineering must not treat the prototype as a production architecture, infer backend authority, begin exceptional scenes, or silently resolve an open product or governance decision.

## Validation recorded for this package

- 24 automated behavior/model tests passed.
- Deterministic-prototype isolation audit passed.
- Static production build passed.
- Live deployment reached `READY` and was aliased to `www.kiduna.design`.
- Design Lab menus and the Inner Clinic scene/story controls were verified in the deployed site.
- Taxonomy impact: **no taxonomy change**.
