What happened
Raw fires, including the ugly ones: duplicates, background fetches, events named after a Jira ticket. We inventory before we moralise.
Method
The Signal Atlas
Four verbs we use on every App Analytics engagement. If a dashboard cannot walk this path, it is furniture.
What it is allowed to mean
A dictionary with owners. Synonyms die here. viewed is not completed, even if the designer hoped it was.
What belongs together
Funnels, cohorts, and sessions that share a clock. Bank holidays in the United Kingdom are not “anomalies”; they are a calendar.
What changes on Tuesday
A chart earns its keep by naming a next action. If nobody will stop a campaign or ship a fix, the tile leaves the wall.
Why a map, not a stack
Vendors change. Warehouses change. The Atlas stays because it is a reading order. Students in Signal Cartography draw their own Atlas on week four; Closed Room teams redraw it after a merger when two taxonomies collide.
We keep a graveyard page. Retired events stay listed so nobody “reuses” checkout_start for a new meaning. That page is unglamorous and more valuable than a colour-coded OKR dashboard.
