## When your documents don't say, Quelvio says so
Four plain kinds of answer, from a full answer to "I didn't find this in the sources you can read." Disagreements are shown, not hidden.
The worst answer is a confident one with nothing behind it. Every Quelvio answer is one of four kinds, and each one reads the same way every time.
- -It answers. The lines that answer, highlighted, each with its source.
- -It partly answers. The lines that answer part of the question. When only a draft says it, the draft is shown under its own heading, "Only a draft says this:", never as the answer.
- -It may answer. "I found nothing that clearly answers this. These may help:", then what came closest.
- -Not found. "I didn't find this in the sources you can read.", then the nearest lines.
Sample · Not found
```textI didn't find this in the sources you can read.
The nearest passages I found:
Trips to London, Paris and Zurich have a daily meal allowance of 60 euros.
Travel and expenses policy · Meals › Expensive cities · 1 March 2026 (stated) · in force · official```## When sources disagree
Quelvio works out which source holds from its versions, its dates, the standing a person gave each source (official, working or informal), and people's rulings. When nothing settles it, you see both under "The sources disagree:", and the people who look after those documents get it to rule on.
Sample · The sources disagree
```textThe sources disagree:
During probation, either side may end the contract with one week's notice. Probation lasts six months.
Employment terms · Probation · 12 November 2026 (read) · status unknown
The notice period during probation is two weeks. Managers confirm the end of probation in writing.
Manager guide · Probation · 12 November 2026 (read) · status unknown```## Why a plain stop
A fixed sentence gives an agent something plain to pass on instead of a guess, and gives a person the nearest lines to go on.
