From a sentence to a fact to an answer.
Quelvio writes down what your sources actually establish, and keeps track of who said it, and when.
Read, write, relate, answer, trace.
Read
Documents and agent sessions, one sentence at a time.
Write facts
Each fact keeps the sentence it came from, who it belongs to, and when it was stated and holds from.
Relate
Facts that agree or disagree are linked, and each keeps its history in time order. Facts are grouped by topic and entity.
Answer
Answers quote the facts they rest on, or decline when the sources don’t settle the question.
Trace
Every step is recorded. Open a reading or an answer and replay how it was built.
Every fact keeps its source.
One sentence from an approved policy becomes one fact, with the four parts that make it checkable.
“From 1 April 2026, volume discounts are capped at 12% for all new contracts.”
Volume discounts on new contracts are capped at 12%.
Sentence

The sentence
quoted, with its document and line.
Who it belongs to
the person, team or party it comes from.
When
the date it was stated, and the date it holds from.
How it relates
the facts it agrees with, disagrees with, or came after.
Every step can be replayed.
The trace of a decline: the question, the facts found, the sources checked, what the sources cover, and the decision.

Outcome
Not sure. Pricing policy v3 covers new contracts only, and the only source on renewals is a Slack message, which isn’t a decision. Finance (Maya Okafor) owns this policy.
