What is ray?
- Ray is an AI compute engine. Ray consists of a core distributed runtime and a set of AI Libraries for accelerating ML workloads.
- Best fit: Users who want source-backed project understanding before installing it.
- Not for: Not for users who want to skip sandbox verification or cannot accept configuration, permission, or maintenance overhead.
- Capability added to an AI workflow: skill, recipe, host_instruction, eval, preflight
- First safe verification step: Verify the smallest path in an isolated environment and keep a rollback path.
- Verification state: source, Quick Start, and sandbox install checks are recorded as passed.
- Top risk: May increase setup, validation, or first-run risk for the user.
- Evidence base: https://github.com/ray-project/ray, https://github.com/ray-project/ray#readme, Human Manual, Pitfall Log

AI Context Pack and portable assets
After deciding to continue, take the project context into your own AI host.Complete pack plus user-owned assets
These files are planning and verification assets for Claude Code, Codex, Gemini, Cursor, ChatGPT, and other AI hosts.

Preflight checks
Treat this page as a planning asset, not proof that your local environment is ready.- The manual is generated from source-linked project files and Doramagic validation signals.
- Community evidence warnings stay visible instead of being converted into marketing claims.
- This English page is indexable because the locale quality gate passed and explicit English index approval is enabled.
- Use the upstream repository as the final authority for installation commands, license, and version-specific behavior.
