# JCOM and Conquer: Design Hub
> Canonical architecture, standards, and skill documentation for JCOM and Conquer game systems.

This hosted node provides authoritative reference material for automated agents, language models (including ChatGPT), and human engineers building game features, 3D assets, simulation logic, maps, and shaders for JCOM and Conquer.

## Primary Documentation
- [README.md](/README.md): Hub overview, standard repositories, and contributor guidelines.
- [ARCHITECTURE.md](/ARCHITECTURE.md): Two-engine architecture, shell modules, simulation tick, rendering, assets, and deployment.
- [REPOS.md](/REPOS.md): Full inventory of simulation repositories, naming conventions, and visibility rules.
- [OPEN-DECISIONS.md](/OPEN-DECISIONS.md): Architectural open decisions and owner rulings (17:02 decisions marked DECIDED).
- [llms-full.txt](/llms-full.txt): Complete concatenated text of all repository README files for single-file ingestion.
- [manifest.json](/manifest.json): Machine-readable source revision manifest and file checksums.

## Design Standards
- [Units Standard](/standards/standards_units/README.md): Coordinate frames (facing -Z, +Y up), dimensions, node naming, joints, and clip rules.
- [Maps Standard](/standards/standards_maps/README.md): Grid cell scales (5m, 20m, 80m), heightmaps, theatres, terrain layers, and water rules.
- [Logic Standard](/standards/standards_logic/README.md): Simulation fixed tick (30 Hz), lockstep determinism, clean-room rules, and mechanics.
- [Geometry Standard](/standards/standards_geometry/README.md): Mesh topology, triangle budgets, LOD derivation, and geometry validation.
- [Lookdev Standard](/standards/standards_lookdev/README.md): PBR materials, textures, texel density (64 px/m game, 512 px/m master), lighting, and tone mapping.
- [Blueprints Standard](/standards/standards_blueprints/README.md): US Navy / US military, third-angle projection, Navy A1 facility sheet, JSLC STD-1 look (standard 0.3.0).

## Service Skills
- [Service Skills Index](/standards/svc_skills/README.md): Catalog of procedural skills for Blender, Substance, blueprints, wireframes, and validation.

## Designer proposals
- [Designer brief](/design-revisions/BRIEF.md): how Claude Design, Astra and other outside designers submit a complete proposal (HUD, menus, logic, units, maps) without asking first.
- [HUD and menus area brief](/design-revisions/AREA-HUD-MENUS.md): the scope, screens and rules for HUD and menu revisions.
- [HUD design system reference](/hud/index.html): the current HUD tokens, components, screens and screenshots (baseline for proposals).
