project
Local-first workout tracker that recomputes coaching verdicts from raw set logs on read, built as native Kotlin/Compose on Android and SwiftUI over a shared Kotlin Multiplatform core on iOS.
No evidence-backed relationships are recorded.
WhyRep bounded its plateau read to 14 misses plus two rows. Any lifter who deloaded once during a stall stopped being told they had plateaued, and nothing logged it.
Reality
A DSN check in Application.onCreate looked airtight and passed four builds. The Sentry provider folded into the merged manifest crashed every launch before that code existed.
Reality
A local-first workout app enforced its privacy rules in beforeSend and unit tested them green. The data that left the browser came from the SDK's own context, on a path no test had inspected.
Reality
A workout app recomputes every coaching verdict from raw logs. That stayed affordable only after seven tables got indices, and the observability added to prove it had been dropping every span.
