Populated from the arc42-template (EN/adoc) with project-specific content
across all 12 sections:
1. Introduction and Goals — requirements overview, quality goals, stakeholders
2. Architecture Constraints — technical (engine, collision, coordinates),
organisational (squash-merge, visual review, provenance), conventions
3. Context and Scope — business and technical context tables
4. Solution Strategy — technology decisions, top-level decomposition,
quality achievement approach
5. Building Block View — Gameplay (6 C++ classes), Site (7 meshes + 7
materials), Facades (9 buildings), Art Pipeline, QA & Review; Level 2
white boxes for input flow and collision model
6. Runtime View — walk, screenshot capture, QA self-test, build/import
pipeline scenarios
7. Deployment View — dev workstation and packaged build infrastructure
8. Cross-cutting Concepts — coordinate system, collision model, lighting,
materials, data provenance, QA harness
9. Architecture Decisions — 7 ADRs (dynamic lighting, UE materials,
C++ collision helper, grounded reset, core ticker, Y convention,
headless Blender)
10. Quality Requirements — overview table + 7 measurable scenarios
11. Risks and Technical Debts — 5 risks, 2 debts with mitigations
12. Glossary — 16 domain-specific terms

|
|
=== Business Context
|
|
|
|
The system is a self-contained single-player game. It has no server backend, no multiplayer, and no live service dependencies. Its communication partners are:
