The Anthropic key was the last hard gate for other users. extract's
VisionFn seam gains a second factory speaking the chat-completions
format — OpenAI, OpenRouter, or a local runtime (Ollama, LM Studio,
llama.cpp, vLLM) via config.toml: vision_provider, vision_base_url,
and vision_key_env ("" = keyless local endpoint, no Authorization
header sent). Anthropic stays the default. load_config rejects unknown
providers loudly, the pipeline page's credentials warning follows the
configured provider (a keyless local endpoint warns about nothing),
and config.toml + README document the local-model trade honestly:
weaker spine reading means a longer proofread pass, which the shaky-
read workflow absorbs.
