Cairn Semantics
Cite or refuse. Receipts for everything.
CAIRN answers questions from your documents with source citations and a hash-sealed receipt — or refuses, on the record. It distills knowledge cards no model can fake, and finds where your own documents disagree before someone else does.
Law matter integrity
The witness said March 12. His own email says the crates were still sealed. And the case that doesn't exist? Refused, on the record.
Data metric integrity
ARR is defined three ways in your own documents — and only one is governed. CAIRN audits everything that cites the law.
Civic public record integrity
The adopted ordinance says ninety days. The published code still says one hundred twenty. Found before a resident's lawyer does.
Refuses structurally
When the corpus can't substantiate an answer, CAIRN declines — by arithmetic, not model goodwill. The refusal itself is sealed.
Everything receipted
Answers, refusals, cards, and audits are entries in a hash-chained ledger. Any after-the-fact edit shows.
Facts survive verification
Knowledge cards keep only facts whose verbatim quotes check character-for-character against their source.
Nothing leaves your box
Zero-dependency core, local models, your hardware. Privilege and PHI stay home.
