Beacon
A platform sold to retailers. It gathers a product's price across sellers, notifies on movement and keeps a compressed price history. The platform takes no side: which channel belongs to whom is tenant data, never code.
The measurement
Price sync does not run in the cloud. It runs inside GitHub Actions with a real Chromium, because plain HTTP requests from cloud IPs hit the bot wall. That was not a guess — it was measured, and the probe is a repeatable workflow file.
Neutral by construction
Every customer registers its own sellers and marks which channel is theirs. If none is marked the app runs in market mode: it watches prices and takes no side.
Built for the floor
Everyone on the sales floor has a phone; only the manager has a laptop. It installs like an app and is designed to be used with one hand.
