Drop the OpenStreetMap/ODbL attribution requirement, the Google imagery rule, and the related F-4 requirement, risk R-4, release check, and TODO items across AGENTS, PLAN, ROADMAP, README, setup, architecture sections, and manifests. OSM data is now documented as local private use only. Also normalize numbered-list indentation in the architecture docs.

# Introduction and Goals
|
||
|
||
Gig Line is a Linux-first Unreal Engine 5 game that reconstructs a walkable (and eventually drivable) stretch of Hollywood Boulevard around 6840 Hollywood Blvd / El Capitan Entertainment Centre. The initial release (`0.1.0`) delivers a first-person walking demo of the south-side block between Highland Avenue and Orange Drive, plus north-side buildings within 50 m of the frontage.
|
||
|
||
## Requirements Overview
|
||
|
||
| ID | Description |
|
||
| --- | --- |
|
||
| F-1 | Walk both sides of Hollywood Blvd in the demo area without falling through geometry |
|
||
| F-2 | First-person movement (WASD + mouse look), jump, reset (R), pause (Escape) |
|
||
| F-3 | Fixed daytime lighting and atmosphere (sun, sky, fog, exposure) |
|
||
| F-5 | Designated street crossing with zebra markings at signalised crossings |
|
||
| F-6 | Building façades recognisable against reference photography |
|
||
| F-7 | Terrain, road, and sidewalk follow real-world DEM elevation |
|
||
| F-8 | 60 FPS at 1440p on the documented workstation and quality preset |
|
||
|
||
Full requirements and progress are in [TODO.md](../../TODO.md); version direction is in [ROADMAP.md](../../ROADMAP.md).
|
||
|
||
## Quality Goals
|
||
|
||
| Priority | Quality Goal | Scenario |
|
||
| --- | --- | --- |
|
||
| 1 | **Performance efficiency** | 60 FPS at 2560×1440 on RTX 5070 Ti, documented preset, no frame generation |
|
||
| 2 | **Terrain walkability** | Zero raycast holes across both sidewalks and the carriageway (84-sample transect passes) |
|
||
| 3 | **Geographic fidelity** | Building placement, street scale, and façade identity match reference photography |
|
||
| 4 | **Build reproducibility** | Fresh checkout + documented engine path produces a runnable Linux build |
|
||
| 5 | **Provenance** | Every committed asset has recorded provenance |
|

## Stakeholders
|
||
|
||
| Role | Contact | Expectations |
|
||
| --- | --- | --- |
|
||
| Owner / Director | zwitschi | Sets scope, approves screenshots, cuts release tags |
|
||
| AI coding agents | multiple sessions | Read `AGENTS.md`, `TODO.md`, `ROADMAP.md`, and this document for architecture constraints; never commit directly to `main` |
|
||
| Players | end users | Walk the demo at 60 FPS without falling through the world; see a recognisable Hollywood block |
