Boundaries matter
Sentence-aware chunks keep ideas intact while overlap gives claims near a boundary another chance to remain visible.
Build a smaller, cited context packet with a local semantic model. Retrieval narrows evidence; it does not prove truth.
Inference runs in this page after the pinned runtime loads. The sample needs no account. Do not paste secrets into a page you do not control.
Run the bundled question to create a real ranked evidence set.

MiniLM maps a paraphrased question and each chunk into the same 384-dimensional space. Cosine similarity orders likely relevance.
A threshold should stop unsupported answering. It needs calibration on your own positive and negative questions.
