Release Windows and Usage Drift

Without a release-aware window, every traffic shift looks mysterious. Tag usage reports by app version and rollout percentage whenever the store or feature flags allow it.

Compare the first seventy-two hours of a staged rollout against the prior stable week, not against an all-time average. Early adopters and forced updates skew the picture.

Document campaign calendars beside release calendars. Marketing pushes and partner events create legitimate usage spikes that should not trigger panic instrumentation rewrites.

When drift remains unexplained, that is a finding: you lacked the dimensions to tell a story. The fix is measurement, not another emergency dashboard.
