# LLM Runtime Architecture

## Procedure

1. Keep `AGENTS.md` as the canonical behavior contract.
2. For each runtime, name entry point, adapter files, available tools, memory
   access, limitations, and verification command.
3. Keep adapters thin and point them back to the canonical core.
4. State unsupported capabilities explicitly.

## Output

Return a runtime matrix with `runtime`, `entry_point`, `adapter_files`,
`memory_access`, `limitations`, and `verification`.
