+# PDIAP-12228 - iOS: Implement interactive components and lifecycle behaviors
+
+## Status
+
+- Backlog item; blocked or unresolved.
+
+---
+
+## Current Understanding
+
+- Covers interactive components such as buttons.
+- Main unresolved question was how to execute JavaScript on mobile.
+
+---
+
+## Historical Slack Context
+
+- November 2025 planning split the SpartaSDK proof-of-concept follow-up into initialization/decoding, rendering, interactive components/lifecycle, and navigation/flow logic tracks.
+- Earlier Slack updates show buttons and dropdown rendering were already partially explored under foundational SpartaSDK work, but full interactive behavior and lifecycle/navigation behavior were not complete.
+- Treat JavaScript execution on mobile as the major unresolved blocker for richer interactive behavior unless current project evidence supersedes it.
