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 whose every quote is machine-verified against its source — unverifiable extractions are dropped, and counted — 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.

drift · § 5-210 · adopted 90 vs codified 120

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.

Zero-dependency core, local models, your hardware. Privilege and PHI stay home.
