Portable air conditioners

Our first catalogue captures a real post-heatwave stock-out. One observation is a starting point—not a trend.

Evidence, not theatre

Every dot needs a source.

01

Identify exactly

Retailer pages and marketplace listings connect to canonical products through validated GTINs and reviewed model evidence.

02

Observe, never rewrite

Every successful price and availability check becomes a dated, immutable observation. Earlier facts stay intact.

03

Show the gaps

A collector failure is not a stock-out. Missing days remain missing, and the latest successful timestamp stays visible.
