Every source needs an owner, date, language, URL, status, and an explicit use boundary.
Transparent workflow
How Janus.Guru builds a verifiable answer
Janus does not look for a ready-made answer on the open internet. It works inside a selected collection: retrieve evidence, assemble a response, and show the basis. When the basis is insufficient, a bounded answer is better than a confident guess.
The path
Five controls between a question and a response
Split into evidence units
Fragments preserve enough context to be useful without turning every page into one opaque block.
Retrieve and rerank
Exact and lexical matching retrieve candidates first. Semantic search is enabled only after full embedding coverage and a separate benchmark. Reranking selects from retrieved candidates; it does not replace search.
Generate with guardrails
The assistant is told which language, format, source policy, and refusal boundary apply.
Review the result
Sources, date, edition, and responsibility stay visible for the person who will use the answer.
