underclass: an OpenAI-compatible pooling proxy that pins sessions to one account (prompt cache stays warm), cools quota-exhausted subscriptions until their window resets, and fails fast with the earliest Retry-After when the whole pool is dry.
Local LLM router. One endpoint for Claude Max/Pro, OpenAI, OpenRouter, Groq, Ollama, LiteLLM, any OpenAI-compat URL — your tools don't need to change. OAuth for Claude subscriptions, multi-account pool, MCP server. Zero runtime deps.
