Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.
We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Optional settings from the registry entry, left out of the block above:
CHAMBER_PYTHON (Path to a Python interpreter with onnxruntime, used by the local embedder. Optional: defaults to python3 on PATH; without onnxruntime, semantic search degrades and Chamber says so), CHAMBER_API_KEY (API key for the configured model endpoint. Only read when model.base is not a loopback address; a local endpoint needs no key).
