Every relation carries the sentence it came from word for word, plus the character offset and line where that sentence stands, and each of those quotes is looked up in the source text before the answer goes out: an exact match, or a match after whitespace is normalised. A relation whose quote cannot be located is returned flagged as unverified and counted separately rather than passed off as a finding, and a relation pointing at an entity the extraction never named is discarded outright, because a model that invents an edge is worse than one that finds nothing — the buyer cannot tell. Dates are handled the same way: the wording is returned verbatim from the text and verified like any other quote, while the ISO form beside it is labelled as a conversion, not as a finding. Entities carry a deterministic identifier derived from their name, so two answers about the same text can be laid against each other. What this endpoint does not do is know anything: it adds no world knowledge, resolves no company against a register, merges no two same-named parties into one, and draws no conclusion the text does not state — what is not in the text is not in the graph. It also does not judge whether a relation is usual, favourable or lawful. The text is processed by a third-party model — the provider, what leaves this machine and what is retained there are named in every answer. Nothing is cached, nothing is written to a database, and no part of the text appears in any log or error message.",
