🎨 Palette: Enhance architecture diagram semantics and visual hierarchy

💡 What

Enhanced the architecture diagram in README.md using Mermaid's semantic features and more granular components:

  • Added a diagram title: "Arbiter Resource Orchestration Architecture".
  • Updated K8s to use a stadium shape ([ ... ]).
  • Updated QS (Quantum Scheduler) to use a hexagon shape {{ ... }}.
  • Added aSHARD VRAM Pinning as a hexagon node in the Infrastructure layer.
  • Applied stroke-dasharray: 5 5 to subgraph borders for better layering distinction.

🎯 Why

In infrastructure-heavy projects like Arbiter, the README.md serves as the primary user interface. A clear, well-structured architecture diagram provides immediate cognitive relief for developers trying to understand how low-level hardware management interacts with cloud-native scheduling. Adding the aSHARD component ensures the diagram accurately represents the project's dual nature as described in the documentation.

♿ Accessibility

  • Added an explicit title to the Mermaid diagram, which can be interpreted by screen readers and provides immediate context.
  • Improved visual hierarchy with distinct node shapes and dashed subgraph borders to help users differentiate between system layers.

- Add title to Mermaid diagram for clarity and accessibility.
- Use semantic node shapes: stadium for Kubernetes cluster, hexagons for specialized components (Quantum Scheduler, aSHARD).
- Add missing aSHARD VRAM Pinning component to the infrastructure layer.
- Update connection flow to accurately reflect resource orchestration.
- Apply dashed borders to subgraphs for better visual distinction between layers.

Code Review

This pull request updates the architecture diagram in the README.md file by adding a title, modifying node shapes, introducing the ASHARD component, and styling the subgraphs with dashed borders. The reviewer suggested changing the space-separated values in the stroke-dasharray styles to comma-separated values to prevent potential parsing errors in some Mermaid renderers.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.
For more details on the timeline and next steps, please review the Help Documentation.

Using spaces in style property values (such as stroke-dasharray: 5 5) can cause parsing errors in some Mermaid renderers, as spaces are often interpreted as delimiters between different style properties. Using a comma-separated value like stroke-dasharray: 5,5 or a single value like stroke-dasharray: 5 is more robust and widely compatible.
