# Artefact — Where-Woof · deployed and pre-market

**Status: running, pre-market.** This is the exact wording the site uses, deliberately: deployed is true, commercial is not.

## What the artefact is

A tag system for lost property. A tag carries a QR code and an RFID identity; whoever finds the item resolves the tag and the owner is contacted. The system is running and being deployed now.

## What it proves

That a product can be taken into the field before it is monetised, and that the honest label for that state exists. The distinction matters on a CV because the alternative — calling a pre-launch product commercial — is the kind of claim a technical interviewer unpicks in one question.

## Limits stated on the page

No customers, no revenue and no launch date are claimed. The metric recorded here is a zero on purpose.

## When it is delivered

The tag and resolve-flow photographs land in Phase 7 if Sam chooses to publish them. Product name and description are approved; commercial framing is not.
