+## InstallAppOperation — self-update backgrounding dropped the `installing` guard (KNOWN, not fixed)
+
+`scheduleSelfUpdateBackgrounding` (InstallAppOperation.swift ~234-263) starts a 3s timer that
+suspends the app's XPC connection so a self-update can finish in the background. Upstream
+SideStore guarded the suspend with a `var installing` flag (set false once `installIPA`
+returned) so it would NOT suspend if the install had already completed. MiniStore dropped the
+flag — the timer now suspends unconditionally once `applicationState == .active`.
+
+**Audited 2026-06-28, deliberately left as-is.** For the self-update path `installIPA` blocks
+until the user leaves the app, so the timer practically always fires while the install is still
+in-flight, making the removed guard a no-op (effect confidence ~0.2). The `applicationState`
+guard is preserved. Re-adding the flag is delicate self-update timing code with near-zero
+upside; only revisit if a self-update is observed force-suspending after completing. To restore
+parity: add `private var installFinished = false`, set it in `installAndFinish`'s success/failure
+paths, and early-return from the timer block when set.
