Field notes
Short writing from engagements—event design, path walks, cohort midnights, and honest scope.
-
Write the events before the tickets
Instrumentation survives when the blueprint exists before the pull request.
-
Permission prompts that quietly break funnels
A cliff in the chart is sometimes an event that never fired after a dialog.
-
KST cohorts and the wrong midnight
Day boundaries move retention cells when warehouses stay on UTC and product thinks in Korea time.
-
What measurement office hours are actually for
Expect judgment on upcoming instrumentation—not a managed dashboard service.
