A local-first CLI over your own notes: the model never sees a document id, so it can't fabricate a citation (MIT)

Mine, MIT, free, nothing to sign up for. Any OpenAI-compatible endpoint including loopback; transcript below is a local 30B. The bit I couldn't get elsewhere: **the model is never in a position to invent a citation.** It's shown `[1]`…`[k]` and never a document id, path or hash — the numbers are resolved back to files *after* the answer is written, and each sentence is judged on its own citations. A sentence citing nothing is marked `UNSUPPORTED`, not treated as load-bearing. When the corpus can't answer, it says so instead of composing something out of the nearest pieces: ``` $ chamber ask "what should a customer do if they want to return a perishable item after the office has closed?" I don't know [APORIA] I don't know ``` Second half: cited passages get hashed, and a scheduled `chamber verify` re-reads them and exits non-zero when one changes — so you find out a conclusion is standing on moved ground without going looking. That half needs no model. Whole loop in one command, throwaway folder, no config/db/model/network: ``` git clone https://github.com/abm9111/chamber && cd chamber npm ci && node --experimental-strip-types src/cli.ts try ``` Caveats, plainly: it proves a cited passage *is* what it claims to be — not that the claim follows from it. Needs Node 23.6+ (runs TS directly, no build step). `docs/KNOWN_LIMITATIONS.md` has 17 entries. Written with AI help and the commit trailers say so; I'd rather be judged on `npm run probes` and the CI'd demos in `demos/`. https://github.com/abm9111/chamber Feedback over stars — is per-sentence citation gating the right granularity, and is there a better answer than hashing for "this source moved under me"?
