 This document provides a structured implementation plan for improving the DailyNotification Android test app based on the improvement directive. The plan focuses on architecture, code organization, testing, and maintainability improvements.

+## Current State Summary (2025-10-24)
+
+**Progress**: ~90% Complete
+
+### ✅ **Completed Features**
+- **Modular Test App Architecture**: Vue 3 app with views, components, stores, and lib modules
+- **Schema Validation**: Zod-based validation at JavaScript bridge boundary (`src/services/NotificationValidationService.ts`, `test-apps/daily-notification-test/src/lib/schema-validation.ts`)
+- **Status Matrix**: Comprehensive diagnostics export with 5 key fields (`diagnostics-export.ts`)
+- **Native Plugin Architecture**: Modular Java classes (34 classes) with specialized managers
+- **Security**: HTTPS enforcement, input validation, proper manifest configuration
+- **Performance**: Performance optimizer, rolling window, TTL enforcement
+- **Logging**: Structured event IDs throughout codebase
+
+### 🚧 **In Progress**
+- **Instrumentation Tests**: Basic tests exist; need expansion for specific scenarios
+- **Documentation**: Runbooks and expanded API reference
+
+### 🎯 **Remaining Work**
+- Add instrumentation tests for critical paths (channel disabled, exact alarm denied, boot recovery)
+- Write operational runbooks for common troubleshooting scenarios
+- Expand API reference documentation with complete method signatures
+
