# P2.1 Batch A - Current State Directive

**Purpose:** State snapshot for reconstituting work on another machine  
**Owner:** Development Team  
**Created:** 2025-12-23  
**Status:** in_progress  
**Baseline:** See `docs/progress/00-STATUS.md` (v1.0.11-p3-complete)

---

## Current Work Status

**Phase:** P2.1 - Native Plugin Refactoring (Batch A)  
**Goal:** Refactor plugin methods to delegate to existing services (thin adapter pattern)  
**Status:** ✅ **BATCH A COMPLETE** — 7 methods refactored, 1 deferred

---

## Completed Refactorings

### ✅ Android: `checkStatus()`

- **File:** `android/src/main/java/com/timesafari/dailynotification/DailyNotificationPlugin.kt`
- **Change:** Delegated to `NotificationStatusChecker.getComprehensiveStatus()`
- **Lines removed:** ~50 lines
- **Service:** `NotificationStatusChecker` (initialized in `load()`)

### ✅ Android: `getNotificationStatus()`

- **File:** `android/src/main/java/com/timesafari/dailynotification/DailyNotificationPlugin.kt`
- **Change:** Delegated to `NotificationStatusChecker.getNotificationStatus()`
- **Implementation:** 
  - Plugin method delegates to `NotificationStatusChecker.getNotificationStatus(database)`
  - Java method calls `NotificationStatusHelper.getNotificationStatusBlocking()` (Kotlin helper)
  - Helper function handles suspend database operations using coroutines
- **Lines removed:** ~35 lines (logic moved to helper)
- **Service:** `NotificationStatusChecker` (initialized in `load()`)
- **Helper:** `NotificationStatusHelper` (Kotlin object with suspend function + Java-compatible blocking wrapper)

### ✅ Android: `checkPermissionStatus()`

- **File:** `android/src/main/java/com/timesafari/dailynotification/DailyNotificationPlugin.kt`
- **Change:** Delegated to `PermissionManager.checkPermissionStatus(call)`
- **Lines removed:** ~47 lines
- **Service:** `PermissionManager` (initialized in `load()` with `ChannelManager` dependency)

### ✅ Android: `isChannelEnabled()`

- **File:** `android/src/main/java/com/timesafari/dailynotification/DailyNotificationPlugin.kt`
- **Change:** Delegated to `ChannelManager` methods
- **Implementation:**
  - Uses `channelManager.ensureChannelExists()` to ensure channel exists
  - Uses `channelManager.isChannelEnabled()` for channel enabled check
  - Uses `channelManager.getChannelImportance()` for importance level
  - Uses `channelManager.getDefaultChannelId()` for channel ID
  - Keeps app-level notification check in plugin (appropriate for plugin layer)
- **Lines removed:** ~37 lines (channel creation/checking logic moved to service)
- **Service:** `ChannelManager` (initialized in `load()`)

### ✅ Android: `isAlarmScheduled()`

- **File:** `android/src/main/java/com/timesafari/dailynotification/DailyNotificationPlugin.kt`
- **Change:** Delegated to `DailyNotificationScheduler.isScheduled()`
- **Implementation:**
  - Added `isScheduled()` method to `DailyNotificationScheduler` (wraps `NotifyReceiver.isAlarmScheduled()`)
  - Plugin method initializes scheduler lazily (requires AlarmManager)
  - Delegates to `scheduler.isScheduled(triggerAtMillis)`
  - Service method checks actual AlarmManager state via PendingIntent
- **Lines removed:** ~5 lines (direct NotifyReceiver call replaced with service delegation)
- **Service:** `DailyNotificationScheduler` (lazy initialization, requires AlarmManager)

### ✅ Android: `getNextAlarmTime()`

- **File:** `android/src/main/java/com/timesafari/dailynotification/DailyNotificationPlugin.kt`
- **Change:** Delegated to `DailyNotificationScheduler.getNextAlarmTime()`
- **Implementation:**
  - Added `getNextAlarmTime()` method to `DailyNotificationScheduler` (wraps `NotifyReceiver.getNextAlarmTime()`)
  - Plugin method initializes scheduler lazily (requires AlarmManager)
  - Delegates to `scheduler.getNextAlarmTime()`
  - Service method gets actual AlarmManager next alarm clock
- **Lines removed:** ~5 lines (direct NotifyReceiver call replaced with service delegation)
- **Service:** `DailyNotificationScheduler` (lazy initialization, requires AlarmManager)

### ✅ Android: `getContentCache()`

- **File:** `android/src/main/java/com/timesafari/dailynotification/DailyNotificationPlugin.kt`
- **Change:** Delegated to `ContentCacheHelper.getLatest()`
- **Implementation:**
  - Created `ContentCacheHelper` Kotlin object with suspend function for database operations
  - Plugin method delegates to `ContentCacheHelper.getLatest(database)`
  - Helper function handles suspend database operations using coroutines
  - Maintains same API behavior (returns latest ContentCache entry)
- **Lines removed:** ~2 lines (direct database call replaced with helper delegation)
- **Helper:** `ContentCacheHelper` (Kotlin object with suspend function, similar to NotificationStatusHelper)

---

## Deferred / Known Issues

### ⚠️ Android: `getExactAlarmStatus()` - Deferred

- **Reason:** `DailyNotificationExactAlarmManager` requires complex initialization:
  - Needs `AlarmManager` (system service)
  - Needs `DailyNotificationScheduler` instance
  - Current initialization pattern doesn't support this easily
- **Status:** Left original implementation with TODO comment
- **Next Step:** Requires refactoring service initialization pattern or creating factory method
- **File:** `android/src/main/java/com/timesafari/dailynotification/DailyNotificationPlugin.kt` (line ~285)

---

## Service Initialization State

### Current Service Instances (in `DailyNotificationPlugin.kt`)

```kotlin
private var statusChecker: NotificationStatusChecker? = null
private var permissionManager: PermissionManager? = null
private var exactAlarmManager: DailyNotificationExactAlarmManager? = null  // ⚠️ null (deferred)
private var channelManager: ChannelManager? = null
private var scheduler: DailyNotificationScheduler? = null  // Lazy initialization (requires AlarmManager)
```

### Initialization in `load()` Method

```kotlin
db = DailyNotificationDatabase.getDatabase(context)
statusChecker = NotificationStatusChecker(context)
channelManager = ChannelManager(context)
permissionManager = PermissionManager(context, channelManager)
exactAlarmManager = null // TODO: Requires AlarmManager + DailyNotificationScheduler
```

**Note:** `exactAlarmManager` is set to `null` because it requires:

- `AlarmManager` from `context.getSystemService(Context.ALARM_SERVICE)`
- `DailyNotificationScheduler` instance (which itself needs initialization)

---

## Modified Files

### `android/src/main/java/com/timesafari/dailynotification/DailyNotificationPlugin.kt`

- **Status:** Modified (unstaged)
- **Changes:**
  - Added service instance variables (lines ~92-95)
  - Updated `load()` method to initialize services (lines ~104-108)
  - Refactored `checkStatus()` method (delegation)
  - Refactored `getNotificationStatus()` method (delegation)
  - Refactored `checkPermissionStatus()` method (delegation)
  - Left `getExactAlarmStatus()` with original implementation + TODO

---

## Batch A Completion Summary

**✅ All Batch A methods successfully refactored!**

**Completed:** 7 methods refactored to use service delegation pattern
- `checkStatus()` → `NotificationStatusChecker`
- `getNotificationStatus()` → `NotificationStatusChecker` + `NotificationStatusHelper`
- `checkPermissionStatus()` → `PermissionManager`
- `isChannelEnabled()` → `ChannelManager`
- `isAlarmScheduled()` → `DailyNotificationScheduler`
- `getNextAlarmTime()` → `DailyNotificationScheduler`
- `getContentCache()` → `ContentCacheHelper`

**Deferred:** 1 method (`getExactAlarmStatus()` - requires complex initialization)

**Code Reduction:** ~181 lines removed from plugin class
**New Helpers Created:** 
- `NotificationStatusHelper` (Kotlin object)
- `ContentCacheHelper` (Kotlin object)

**Service Methods Added:**
- `NotificationStatusChecker.getNotificationStatus()`
- `DailyNotificationScheduler.isScheduled()`
- `DailyNotificationScheduler.getNextAlarmTime()`

---

## Next Steps (Batch B)

**Remaining methods** (may require more complex initialization or service setup):

- Additional methods from Batch B plan (`docs/progress/P2.1-BATCH-2.md`)
- Methods requiring complex service dependencies
- Methods with validation/transformation logic

### Service Initialization Needs

Before continuing, may need to:

- Initialize `DailyNotificationScheduler` (requires `AlarmManager`)
- Initialize `DailyNotificationStorage` (may already exist via database)
- Create factory method for `DailyNotificationExactAlarmManager` initialization

---

## Reference Documentation

- **Batch A Plan:** `docs/progress/P2.1-BATCH-1.md`
- **Method-Service Map:** `docs/progress/P2.1-METHOD-SERVICE-MAP.md`
- **Batch B Plan:** `docs/progress/P2.1-BATCH-2.md`
- **Overall Status:** `docs/progress/00-STATUS.md`

---

## Verification Checklist

Before committing or continuing:

- [ ] Run `./ci/run.sh` (must pass)
- [ ] Verify Android plugin compiles
- [ ] Check that refactored methods still work (manual test or unit test)
- [ ] Verify no breaking API changes
- [ ] Update progress docs if needed

## Commit Message Template

```
refactor(android): P2.1 Batch A - delegate status/permission methods to services

- Refactor checkStatus() to delegate to NotificationStatusChecker
- Refactor getNotificationStatus() to delegate to NotificationStatusChecker  
- Refactor checkPermissionStatus() to delegate to PermissionManager
- Add service instance variables and initialization in load()
- Defer getExactAlarmStatus() (requires complex service initialization)

Reduces plugin class complexity by ~130 lines.
Services already exist - this is delegation, not extraction.

Refs: docs/progress/P2.1-BATCH-1.md
```

---

## Key Decisions Made

1. **Delegation over Extraction:** Services already exist, so we're delegating, not extracting
2. **Incremental Approach:** Batch A focuses on pure delegation (lowest risk)
3. **Service Initialization:** Using lazy initialization pattern with null checks
4. **Complex Services:** Deferring methods that require complex initialization (like `exactAlarmManager`)

---

## Testing Notes

- **Unit Tests:** Should verify service methods are called correctly
- **Integration Tests:** Should verify plugin API behavior unchanged
- **Manual Testing:** Test each refactored method to ensure behavior preserved

---

## Rollback Plan

If issues arise:

1. Revert commits for this batch
2. Service methods remain unchanged (no risk)
3. Plugin methods can be restored from git history
4. No breaking changes to public API
