Silent misses only show up on a device walk
Live streams reveal gaps that warehouse queries never mention.
Warehouse aggregates hide the moment an event never fired. A permission prompt on Android, a web-to-app handoff, or a client-only confirmation can erase a step without leaving an error row.
Before rewriting onboarding, walk the path on devices your users hold and watch the stream. Note every silent miss. Ask whether the step is client-only, server-confirmed, or both.
Identity resets between surfaces create ghost abandoners: people who continued elsewhere look like new entrants who quit mid-path.
Conversion Path Instrumentation engagements stay deliberately narrow—one path, deep QA, a script you can rerun after every release.
