Every claim. Verified.

ENGINE OVERVIEW

Verification architecture. Not a wrapper.

LIMMA is a deterministic verification engine that sits between the LLM and the end user. The LLM generates language. LIMMA verifies facts.

01DETERMINISTIC MATH

The LLM reads. LIMMA computes.

LLMs never do math. 50+ deterministic tools handle every computation — margin analysis, growth rates, full DCF models — with exact-precision arithmetic. The LLM identifies inputs; LIMMA's engine does the math.

02CLAIM VERIFICATION

Every claim independently verified.

A Unified Classifier extracts every factual claim and classifies it — numeric, percentage, entity, comparison. Each one verified against source documents using type-specific strategies.

03SELF-HEALING

Wrong answers corrected, not delivered.

The Reinjection Engine applies direct substitution first, then rebuilds with source data, then flags as unverifiable. Errors are never silently passed through.

04TRACEABILITY

Full traceability. Every number proven.

Every number traces to a source document or deterministic calculation with a proof string. Complete audit logs for compliance.

Failed claims don't get rejected. They get fixed.

Limma corrects hallucinations claim-by-claim, re-verifies each fix against source documents, and returns a clean response.
