# ARUON Research — how we work

Screen, don't decide: every report is ranked evidence, sourced figures and named gaps for a person to judge — not a verdict.

## One steep reading is not “no pad”.

On a site search, slope colours a site's topography flag. A site leaves the list on slope only when a measured slope is over that search's own grade ceiling; a slope we could not measure is printed as a gap, never as a reason to drop the site.

## A tax roll cannot see the ground.

We never call a parcel vacant from the tax roll alone. The roll's code prints as the roll's own record; whether the ground is clear comes from mapped building outlines, and where the roll and the outlines disagree, the outlines win or the site reads “unread”.

## Unread zoning is named, not guessed.

Where we have not read the jurisdiction's own zoning map, the report says so and names the office to ask. We never derive a zoning district from a parcel's use code or its neighbours.

## Assessed value is the tax anchor.

An assessed value prints as the assessor's tax assessment — a labelled reference anchor, not a market value, an appraisal or a price. In a non-disclosure state the report says why it sits further from market.

## Every report

- Every figure carries its source. Dataset, exact vintage, pull date, how-to-verify — per figure, in the report you receive.
- An absent value is a named gap. We print what we could not get and who we asked for it. An absent source is a named gap, not a guess.
- A person signs every release. Nothing auto-sends. An analyst reviews each report, approves it personally, and the release is recorded in a ledger.
