feat(docs): complete P2.6 type safety cleanup and P2.7 system invariants

P2.6: Type Safety Cleanup
- Replaced 'any' return types in vite-plugin.ts with concrete types (UserConfig, transform return type)
- Documented TypeScript mixin 'any[]' exception in PlatformServiceMixin.ts
- Audit confirmed: zero 'any' in codebase except documented TS mixin limitation
- All external boundaries use 'unknown', all data payloads use 'Record<string, unknown>'

P2.7: System Invariants Documentation
- Created SYSTEM_INVARIANTS.md documenting all 6 enforced invariants
- Added to docs/00-INDEX.md under Policy & Contracts section
- Each invariant includes: What, Why, How, Where

Progress Docs Updates:
- Updated 00-STATUS.md: marked P2.6/P2.7 complete, added type safety invariant note
- Updated 01-CHANGELOG-WORK.md: added 2025-12-22 entries for P2.6/P2.7
- Updated 03-TEST-RUNS.md: added P2.6 type safety audit test run
- Updated P2-DESIGN.md: marked P2.6 acceptance criteria complete
- Updated SYSTEM_INVARIANTS.md: added Type Safety Notes section

Baseline Tag:
- Created v1.0.11-p0-p1.4-p1.5-p2.6-p2.7-complete

TypeScript compilation:  PASSES
Build:  PASSES
CI:  All checks pass

# Background Data Fetching Implementation Plan
**Author**: Matthew Raymer
**Version**: 1.0.0
**Created**: 2025-10-02 07:47:04 UTC
**Last Updated**: 2025-10-02 12:45:00 UTC
## Overview
This document outlines the **enhancement plan** for background data fetching in the Daily Notification Plugin to support TimeSafari integration with Option A architecture. This plan builds upon our existing implementation and adds:
- **Option A Enhancement**: ActiveDid-aware authentication on existing infrastructure
- **TimeSafari Integration**: PlatformServiceMixin coordination with current plugin
- **Authentication Layer**: JWT/DID support over existing HTTP callback system
- **Database Enhancement**: Extend current storage with activeDid management
- **Event & Change Management**: Identity change detection on existing notification system
- **API Integration**: Endorser.ch endpoints through current ContentFetchConfig
This document serves as the enhancement roadmap for adding TimeSafari capabilities to our existing, working plugin.
## Current Implementation Baseline
### ✅ Already Implemented & Working
- **Android Storage**: SharedPreferences + SQLite with migration (`DailyNotificationStorage.java`, `DailyNotificationDatabase.java`)
- **Web Storage**: IndexedDB with comprehensive service worker (`sw.ts`, `IndexedDBManager`)
- **Callback System**: HTTP/local callbacks with circuit breaker (`callback-registry.ts`)
- **Configuration**: Database path, TTL, retention settings (`ConfigureOptions`)
- **ETag Support**: Conditional HTTP requests (`DailyNotificationETagManager.java`)
- **Dual Scheduling**: Content fetch + user notification separation
- **Cross-Platform API**: Unified TypeScript interface (`DailyNotificationPlugin`)
### ⚠️ Enhancement Required for TimeSafari
- **ActiveDid Integration**: Add activeDid-awareness to existing authentication
- **JWT Generation**: Enhance HTTP layer with DID-based tokens
- **Identity Change Detection**: Add event listeners to existing callback system
- **Endorser.ch APIs**: Extend `ContentFetchConfig` with TimeSafari endpoints
- **Platform Auth**: Add Android Keystore/iOS Keychain to existing storage
## Consolidated Architecture: Option A Platform Overview
```
TimeSafari Host App
↓ (provides activeDid)
Daily Notification Plugin → Native Background Executor
HTTP Client + Auth
API Server Response
Parse & Cache Data (plugin storage)
Trigger Notifications
```
### **Option A: Host Always Provides activeDid**
**Core Principle**: Host application queries its own database and provides activeDid to plugin.
### **Why Option A Is Superior:**
1. **Clear Separation**: Host owns identity management, plugin owns notifications
2. **No Database Conflicts**: Zero shared database access between host and plugin
3. **Security Isolation**: Plugin data physically separated from user data
4. **Platform Independence**: Works consistently regardless of host's database technology
5. **Simplified Implementation**: Fewer moving parts, clearer debugging
## Android Implementation Strategy
### A. Background Execution Framework
- **Use WorkManager** for reliable background HTTP requests
- **Enhance** existing Native HTTP clients (already implemented):
- Extend `DailyNotificationETagManager.java` with JWT headers
- Add JWT authentication to `DailyNotificationFetcher.java`
- **Handle Android-specific constraints**: Doze mode, app standby, battery optimization
### B. Authentication Enhancement - Extend Current Infrastructure
**Goal**: Enhance existing `DailyNotificationETagManager.java` and `DailyNotificationFetcher.java` with JWT authentication
```kotlin
// Enhance existing Android infrastructure with JWT authentication
class DailyNotificationJWTManager {
private val storage: DailyNotificationStorage
private val currentActiveDid: String? = null
// Add JWT generation to existing fetcher
fun generateJWTForActiveDid(activeDid: String, expiresInSeconds: Int): String {
val payload = mapOf(
"exp" to (System.currentTimeMillis() / 1000 + expiresInSeconds),
"iat" to (System.currentTimeMillis() / 1000),
"iss" to activeDid,
"aud" to "timesafari.notifications",
"sub" to activeDid
)
return signWithDID(payload, activeDid)
}
// Enhance existing HTTP client with JWT headers
fun enhanceHttpClientWithJWT(connection: HttpURLConnection, activeDid: String) {
val jwt = generateJWTForActiveDid(activeDid, 60)
connection.setRequestProperty("Authorization", "Bearer $jwt")
connection.setRequestProperty("Content-Type", "application/json")
}
}
### C. HTTP Request Enhancement - Extend Existing Fetcher
**Goal**: Enhance existing `DailyNotificationFetcher.java` with Endorser.ch API support
```kotlin
// Enhance existing DailyNotificationFetcher.java with TimeSafari APIs
class EnhancedDailyNotificationFetcher : DailyNotificationFetcher {
private val jwtManager: DailyNotificationJWTManager
suspend fun fetchEndorserOffers(activeDid: String, afterId: String?): Result {
val connection = HttpURLConnection("$apiServer/api/v2/report/offers")
// Add JWT authentication to existing connection
jwtManager.enhanceHttpClientWithJWT(connection, activeDid)
// Add Endorser.ch specific parameters
connection.setRequestProperty("recipientDid", activeDid)
if (afterId != null) {
connection.setRequestProperty("afterId", afterId)
}
// Use existing storeAndScheduleNotification method
return fetchAndStoreContent(connection)
}
}
```
## iOS Implementation Strategy
### A. Background Execution Framework
- **Use BGTaskScheduler** for background HTTP requests
- **Replace axios** with native iOS HTTP clients:
- URLSession for HTTP requests
- Combine framework for async/await patterns
### B. Authentication Implementation
```swift
// JWT Generation in iOS
class JWTHelper {
func generateJWT(userDid: String, expiresInSeconds: Int) -> String {
let payload: [String: Any] = [
"exp": Int(Date().timeIntervalSince1970) + expiresInSeconds,
"iat": Int(Date().timeIntervalSince1970),
"iss": userDid
]
return signWithDID(payload, userDid)
}
}
```
### C. HTTP Request Implementation
```swift
// Background HTTP Task
class DataFetchTask {
func fetchData() async {
let jwt = generateJWT(userDid: activeDid, expiresInSeconds: 60)
var request = URLRequest(url: apiURL)
request.setValue("Bearer \(jwt)", forHTTPHeaderField: "Authorization")
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
do {
let (data, _) = try await URLSession.shared.data(for: request)
let offersResponse = try JSONDecoder().decode(OffersResponse.self, from: data)
await scheduleNotification(with: offersResponse.data)
} catch {
// Handle errors
}
}
}
```
## Data Models & Type Safety
### Shared TypeScript Interfaces
```typescript
// Definitions for native bridge
interface OffersResponse {
data: OfferSummaryRecord[];
hitLimit: boolean;
}
interface OfferSummaryRecord {
jwtId: string;
handleId: string;
issuedAt: string;
offeredByDid: string;
recipientDid: string;
unit: string;
amount: number;
// ... other fields
}
```
### Native Implementations
- **Kotlin sealed classes** for type-safe responses
- **Swift Codable structs** for JSON parsing
- **Shared error handling** patterns
## Configuration Management
### Plugin Configuration
```typescript
interface PluginConfig {
apiServer: string;
jwtExpirationSeconds: number;
requestTimeoutMs: number;
retryAttempts: number;
activeDid: string; // Simplified to single active DID
lastKnownOfferId?: string;
lastKnownPlanId?: string;
}
```
### Platform-Specific Settings
- **Android**: Manage API keys in `AndroidManifest.xml`, use SharedPreferences for runtime config
- **iOS**: Use `Info.plist` for static config, UserDefaults for runtime settings
## Error Handling & Resilience
### Network Error Handling
- **Connectivity checks** before making requests
- **Exponential backoff** for retry scenarios
- **Circuit breaker pattern** for API failures
- **Graceful degradation** when offline
### Authentication Error Handling
- **Token refresh** mechanisms
- **Fallback to anonymous** requests when authentication fails
- **Secure credential storage** using platform keychains
## Cache & State Management
### Data Persistence
#### **Platform-Specific Storage Architecture**
**Android/Electron Platforms:**
- **@capacitor-community/sqlite** plugin integration for native SQLite access
- **Shared plugin database** - Plugin manages its own SQLite database instance
- **Direct SQL execution** via plugin's `dbExec()` methods for complex queries
- **Background worker integration** for database operations during content fetch
**Web Platform:**
- **absurd-sql** for SQLite support in browser (managed by host application)
- **Plugin delegation pattern** - Plugin provides SQL queries, host executes them
- **IndexedDB fallback** for basic caching when SQLite unavailable
**iOS Platform:**
- **Core Data integration** via native Swift implementation
- **Background task compatibility** with iOS background refresh constraints
### State Synchronization
- **JavaScript → Native** configuration updates
- **Native → JavaScript** status reporting
- **Cross-platform state consistency**
- **Background ↔ Foreground** state synchronization
- **Database logging** for audit trails and debugging
### Enhanced Caching Strategy
Based on TimeSafari's optimization patterns:
- **Batch-oriented processing** for API requests to reduce overhead
- **Intelligent batching** with configurable timing (max 100ms wait, max 10 items)
- **Memory-optimized caching** with automatic cleanup (keep last 1000 log entries)
- **Request deduplication** to prevent redundant API calls
- **Performance monitoring** with operation timing and metrics collection
## Performance Optimizations
### Request Optimization
- **Deduplication** of identical requests
- **Batch requests** when possible
- **Intelligent polling** based on user activity
### Memory Management
- **Background memory limits** enforcement
- **Cache cleanup** on memory pressure
- **Resource lifecycle** management
## Critical Requirement: Plugin Must Know When activeDid Changes
### **Security Implications of Missing ActiveDid Change Detection**
**Without immediate activeDid change detection, the plugin faces severe risks:**
- **Cross-User Data Exposure**: Plugin fetches notifications for wrong user after identity switch
- **Unauthorized API Access**: JWT tokens valid for incorrect user context
- **Background Task Errors**: Content fetching operates with wrong identity
### **Event-Based Solution**
**Host Application Responsibility**: Dispatch `activeDidChanged` event
```typescript
// TimeSafari PlatformServiceMixin modification
async $updateActiveDid(newDid: string | null): Promise<void> {
// Update TimeSafari's active_identity table (existing logic)
await this.$dbExec(
"UPDATE active_identity SET activeDid = ?, lastUpdated = datetime('now') WHERE id = 1",
[newDid || ""]
);
// CRITICAL: Notify plugin of change IMMEDIATELY
document.dispatchEvent(new CustomEvent('activeDidChanged', {
detail: { activeDid: newDid }
}));
}
```
**Plugin Responsibility**: Listen and respond to changes
```typescript
// Plugin service layer implementation
plugin.onActiveDidChange(async (newActiveDid) => {
// 1. Clear all cached content for previous identity
await plugin.clearCacheForNewIdentity();
// 2. Refresh authentication tokens with new activeDid
await plugin.refreshAuthenticationForNewIdentity(newActiveDid);
// 3. Restart background tasks with correct identity
await plugin.updateBackgroundTaskIdentity(newActiveDid);
logger.info(`[DailyNotificationService] ActiveDid updated to: ${newActiveDid}`);
});
```
## TimeSafari Integration Patterns
### **ActiveDid Management Analysis**
**TimeSafari's Database Architecture:**
- **Table**: `active_identity` (single row with `id = 1`)
- **Content**: `activeDid TEXT`, `lastUpdated DATETIME`
- **Purpose**: Single source of truth for active user identity
**Access via PlatformServiceMixin:**
```typescript
// Retrieving activeDid in TimeSafari components
const activeIdentity = await this.$getActiveIdentity();
const activeDid = activeIdentity.activeDid;
// Updating activeDid via PlatformServiceMixin
async $updateActiveDid(newDid: string | null): Promise<void> {
await this.$dbExec(
"UPDATE active_identity SET activeDid = ?, lastUpdated = datetime('now') WHERE id = 1",
[newDid || ""]
);
}
```
### **Plugin Hosting Strategy**
**Existing Plugin Usage**: TimeSafari already uses Capacitor plugins extensively via `CapacitorPlatformService.ts`
**Recommended Integration Architecture:**
- Plugin integrates as standard Capacitor plugin
- Host provides activeDid via event-driven pattern
- Plugin manages own isolated storage
- Clear separation of responsibilities maintained
## Integration Points
### Enhanced Plugin Interface for Host Application Integration
#### **Database Integration Patterns**
**Android/Electron: Host-Provided activeDid Approach (Option A)**
```typescript
// Host queries its own database and provides activeDid
const activeIdentity = await this.$getActiveIdentity(); // Uses host's CapacitorSQLite
await plugin.setActiveDidFromHost(activeIdentity.activeDid);
// Plugin configures its own isolated database
await plugin.configureDatabase({
platform: 'android',
storageType: 'plugin-managed' // Plugin owns its storage
});
// Set up activeDid change listener for future changes
plugin.onActiveDidChange(async (newActiveDid) => {
await plugin.clearCacheForNewIdentity();
await plugin.refreshAuthenticationForNewIdentity(newActiveDid);
logger.info(`[TimeSafari] ActiveDid changed to: ${newActiveDid}`);
});
```
**Web: Host-Provided activeDid Approach (Option A)**
```typescript
// Host queries its absurd-sql database and provides activeDid
const activeIdentity = await this.$getActiveIdentity(); // Uses host's absurd-sql
await plugin.setActiveDidFromHost(activeIdentity.activeDid);
// Plugin uses host-delegated storage for its own data
await plugin.configureDatabase({
platform: 'web',
storageType: 'host-managed' // Plugin delegates to host for storage
});
// Plugin operates independently with provided activeDid
const results = await plugin.executeContentFetch(contentConfig);
```
**iOS: Host-Provided activeDid Approach (Option A)**
```typescript
// Host queries its CapacitorSQLite database and provides activeDid
const activeIdentity = await this.$getActiveIdentity(); // Uses host's CapacitorSQLite
await plugin.setActiveDidFromHost(activeIdentity.activeDid);
// Plugin configures its own Core Data storage
await plugin.configureDatabase({
platform: 'ios',
storageType: 'plugin-managed' // Plugin owns Core Data storage
});
// Plugin operates with provided activeDid, no database sharing needed
const results = await plugin.executeBackgroundContentFetch();
```
#### **Enhancement Required: Extend Current Plugin Interface**
**Current Interface** (already implemented):
```typescript
interface DailyNotificationPlugin {
configure(options: ConfigureOptions): Promise<void>;
scheduleContentFetch(config: ContentFetchConfig): Promise<void>;
scheduleUserNotification(config: UserNotificationConfig): Promise<void>;
// ... existing methods (see definitions.ts)
}
```
**Enhancement Required** (add to existing interface):
```typescript
interface EnhancedDailyNotificationPlugin extends DailyNotificationPlugin {
// Enhanced configuration with activeDid support
configure(options: ConfigureOptions & {
activeDidIntegration?: {
platform: 'android' | 'ios' | 'web' | 'electron';
storageType: 'plugin-managed' | 'host-managed';
};
}): Promise<void>;
// Host-provided activeDid Management (Option A Implementation)
setActiveDidFromHost(activeDid: string): Promise<void>;
// Critical: ActiveDid Change Handling
onActiveDidChange(callback: (newActiveDid: string) => Promise<void>): void;
refreshAuthenticationForNewIdentity(activeDid: string): Promise<void>;
}
```
### Background Scheduling with Hybrid activeDid Management
- **Integrate** with existing WorkManager/BGTaskScheduler
- **Coordinate** API fetch timing with notification schedules
- **Handle** app lifecycle events (background/foreground)
- **Implement** host-provided activeDid access (Option A):
- **Always**: Host provides activeDid via `setActiveDidFromHost()`
- **No Database Sharing**: Plugin never accesses TimeSafari's active_identity table
- **Critical**: Plugin **MUST** know when activeDid changes for:
- **Event-Based Notification**: Host dispatches `activeDidChanged` events
- **Cache Invalidation**: Clear cached content when user switches identity
- **Token Refresh**: Generate new JWT tokens with updated active Did
- **Background Task Coordination**: Restart tasks with new identity context
- **Maintain** clear separation: Host owns identity management, plugin owns notifications
## Migration & Testing Strategy
### Gradual Migration
1. **Phase 1**: Implement basic HTTP + JWT authentication
2. **Phase 2**: Add caching and state management
3. **Phase 3**: Integrate with notification scheduling
4. **Phase 4**: Add passkey authentication support
### Testing Approach with Host-Provided activeDid Management
- **Unit tests** for JWT generation and HTTP clients with activeDid
- **Integration tests** for API endpoint interactions using TimeSafari active_identity patterns
- **Host-provided activeDid testing**:
- Test `setActiveDidFromHost()` with TimeSafari PlatformServiceMixin
- Test host event dispatch and plugin event listening
- **Critical**: Test `onActiveDidChange()` listener with identity switches
- Test cache invalidation and token refresh during activeDid changes
- Verify database isolation between host and plugin
- **Background testing** on real devices (doze mode, app backgrounding)
- **Authentication testing** with actual DID credentials from TimeSafari active_identity table
- **Cross-platform testing** for Android/Electron (SQLite access) vs Web (host delegation) patterns
## API Endpoints to Support
### Offers to User Endpoint
```
GET {apiServer}/api/v2/report/offers?recipientDid={userDid}&afterId={jwtId}&beforeId={jwtId}
```
**Response Structure:**
```json
{
"data": Array<OfferSummaryRecord>,
"hitLimit": boolean
}
```
### Offers to User Projects Endpoint
```
GET {apiServer}/api/v2/report/offersToPlansOwnedByMe?afterId={jwtId}&beforeId={jwtId}
```
**Response Structure:**
```json
{
"data": Array<OfferToPlanSummaryRecord>,
"hitLimit": boolean
}
```
## Authentication Implementation Strategy
### Option 1: Simple DID Authentication (Basic)
- Generate traditional JWT using DID signing
- Short-lived tokens (60 seconds)
- Suitable for basic notification data fetching
- Use `did-jwt` library for token generation and verification
- Based on TimeSafari's existing JWT implementation patterns
### Option 2: Enhanced Passkey Authentication (Advanced)
- Leverage device biometrics/security keys
- Longer-lived tokens with automatic refresh
- Support for cached authentication state
- Better user experience for frequent polling
- Integrate with SimpleWebAuthn for cross-platform biometric support
- Support JWANT tokens (JWT + WebAuthn) for enhanced security
## Platform-Specific Considerations
### Android Considerations
- Use OkHttp or native Android HTTP clients
- Handle certificate pinning if required
- Support Android Keystore for secure key storage
- Handle biometric prompt integration for passkeys
### iOS Considerations
- Use URLSession for HTTP requests
- Support iOS Keychain for authentication tokens
- Handle Face ID/Touch ID integration for passkeys
- Support certificate pinning if required
- Use BGTaskScheduler for reliable background execution
- Handle iOS-specific background refresh restrictions
- Support Core Data for notification metadata persistence
## Data Flow Integration Points
### Token Generation
- Accept activeDid as input
- Generate JWT authentication token using DID signing
- Include activeDid as both issuer (`iss`) and subject (`sub`)
- Return token for immediate use or caching
### Request Execution
- Construct full API URLs with query parameters
- Apply authentication headers
- Execute HTTP requests with proper error handling
- Return structured response data
### Caching Strategy
- Support token caching with expiration management
- Implement request deduplication for same endpoints
- Support cache invalidation for authentication failures
## Implementation Phases
### Phase 1: Extend Core Infrastructure (Building on Existing)
- **Extend existing** Android `DailyNotificationFetcher.java` with JWT authentication
- **Enhance existing** iOS implementation (when added) with authentication layer
- **Add JWT generation** to existing `DailyNotificationETagManager.java`
- **Enhance current** `ConfigureOptions` with activeDid integration
- **Build on existing** error handling (circuit breaker already implemented)
### Phase 2: ActiveDid Integration & TimeSafari API Enhancement
- **Add** host-provided activeDid management to existing plugin interface
- **Extend** existing `configure()` method with activeDid options
- **Enhance** existing `ContentFetchConfig` with Endorser.ch API endpoints
- **Add** `setActiveDidFromHost()` and `onActiveDidChange()` to existing interface
- **Integrate** existing `callback-registry.ts` with activeDid-aware callbacks
- **Enhance** existing platform storage:
- **Android**: Extend existing SQLite with activeDid-aware JWT storage
- **Web**: Enhance existing IndexedDB with activeDid support (no host delegation needed initially)
### Phase 3: Background Enhancement & TimeSafari Coordination
- **Enhance** existing WorkManager integration with activeDid-aware workers
- **Coordinate** existing notification scheduling with TimeSafari PlatformServiceMixin
- **Extend** existing app lifecycle handling with activeDid change detection
- **Enhance** existing state synchronization with identity management
- **Critical: Enhance retry policies** for activeDid changes:
- **Android**: Modify `DailyNotificationFetchWorker.java` retry logic to detect activeDid changes during retry sequence
- **Web**: Enhance `callback-registry.ts` to refresh authentication before retry attempts
- **Unify**: Standardize retry delays across platforms (Android 1min→1hour vs Web 1sec→1min)
- **Integrate activeDid change detection** into existing circuit breaker and error handling systems
### Phase 4: TimeSafari Integration & Advanced Features
- **Integrate** with TimeSafari's existing PlatformServiceMixin patterns
- **Add** Endorser.ch API endpoint support to existing `ContentFetchConfig`
- **Implement** DID-based authentication alongside existing callback system
- **Enhance** existing testing with TimeSafari-specific scenarios
## Current Scheduled Event Update Policies
### ✅ **Existing Consistent Policies**
- **Retry Logic**: Exponential backoff with platform-specific limits (Android: 5 retries, Web: 5 retries)
- **Circuit Breaker**: Opens after 5 consecutive failures
- **Fallback Content**: Uses cached/emergency content when all retries fail
- **ETag Updates**: Conditional requests with 304 Not Modified handling
- **Error Classification**: Network/Storage errors retryable, Permission/Config errors not retryable
### ⚠️ **Enhancement Required for TimeSafari Integration**
- **ActiveDid Change Detection**: Handle identity switches during scheduled events
- **Authentication Refresh**: Update JWT tokens for ongoing retry attempts
- **Cache Invalidation**: Clear cached content when activeDid changes
- **Platform Policy Unification**: Standardize retry delays and fallback mechanisms
### **TimeSafari-Aware Update Policy**
```typescript
interface TimeSafariUpdatePolicy extends ContentFetchConfig {
activeDidAwareRetry?: {
maxRetriesDuringActiveDidChange: number; // More retries during identity change
authenticationRefreshDelay: number; // Time to refresh auth before retry
cacheInvalidationOnChange: boolean; // Clear cache when activeDid changes
};
}
```
## Success Criteria
- [ ] **Functional Requirements**: API data fetching works reliably in background with activeDid awareness
- [ ] **Performance Requirements**: Requests complete within 30 seconds, including authentication refresh
- [ ] **Security Requirements**: ActiveDid-based authentication with token refresh during retries
- [ ] **Reliability Requirements**: Enhanced retry policies that handle activeDid changes gracefully
- [ ] **Integration Requirements**: Seamless integration with existing plugin APIs + TimeSafari patterns
- [ ] **Testing Requirements**: Comprehensive test coverage including activeDid change scenarios
- [ ] **Authentication Requirements**: DID-based JWT with automatic refresh during scheduled events
- [ ] **Optimization Requirements**: Intelligent retry policies based on error type and activeDid state
- [ ] **Logging Requirements**: Structured logging with activeDid context and retry state tracking
- [ ] **Cross-Platform Requirements**: Unified activeDid-aware retry and fallback mechanisms
## Risks & Mitigation
### Technical Risks
- **Background execution limits**: Mitigated by using platform-specific background task systems
- **Authentication complexity**: Mitigated by implementing gradual migration path
- **Cross-platform consistency**: Mitigated by shared interfaces and careful API design
### Timeline Risks
- **Platform-specific complexity**: Mitigated by prioritizing Android first, then iOS
- **Testing complexity**: Mitigated by automated testing and CI/CD integration
- **Integration challenges**: Mitigated by maintaining backward compatibility
---
**Status**: Enhancement plan for existing implementation (Option A) - Ready for implementation
**Next Steps**: Begin Phase 1 - enhance existing Android HTTP infrastructure with JWT authentication
**Dependencies**: Existing plugin infrastructure, Android Studio, Capacitor CLI, TimeSafari PlatformServiceMixin
**Enhancement Approach**:
- **Build on Existing**: Leverage current SQLite, IndexedDB, callback system, and dual scheduling

# Build Script Improvements
**Date:** 2025-11-13
**Status:****FIXED**
---
## Issues Fixed
### 1. Missing Build Folder ✅
**Problem:**
- Script was looking for `build` directory: `find build -name "*.app"`
- Xcode actually builds to `DerivedData`: `~/Library/Developer/Xcode/DerivedData/App-*/Build/Products/`
**Solution:**
- Updated script to search in `DerivedData`:
```bash
DERIVED_DATA_PATH="$HOME/Library/Developer/Xcode/DerivedData"
APP_PATH=$(find "$DERIVED_DATA_PATH" -name "App.app" -path "*/Build/Products/Debug-iphonesimulator/*" -type d 2>/dev/null | head -1)
```
**Result:** ✅ App path now correctly detected
---
### 2. Simulator Not Launching ✅
**Problem:**
- Script only built the app, didn't boot or launch simulator
- No automatic deployment after build
**Solution:**
- Added automatic simulator boot detection and booting
- Added Simulator.app opening if not already running
- Added boot status polling (waits up to 60 seconds)
- Added automatic app installation
- Added automatic app launch (with fallback methods)
**Implementation:**
```bash
# Boot simulator if not already booted
if [ "$SIMULATOR_STATE" != "Booted" ]; then
xcrun simctl boot "$SIMULATOR_ID"
open -a Simulator # Open Simulator app
# Wait for boot with polling
fi
# Install app
xcrun simctl install "$SIMULATOR_ID" "$APP_PATH"
# Launch app
xcrun simctl launch "$SIMULATOR_ID" com.timesafari.dailynotification.test
```
**Result:** ✅ Simulator now boots and app launches automatically
---
## Improvements Made
### Boot Detection
- ✅ Polls simulator state every second
- ✅ Waits up to 60 seconds for full boot
- ✅ Provides progress feedback every 5 seconds
- ✅ Adds 3-second grace period after boot detection
### App Launch
- ✅ Tries direct launch first
- ✅ Falls back to console launch if needed
- ✅ Provides manual instructions if automatic launch fails
- ✅ Handles errors gracefully
### Error Handling
- ✅ All commands have error handling
- ✅ Warnings instead of failures for non-critical steps
- ✅ Clear instructions for manual fallback
---
## Current Behavior
1. ✅ **Builds** the iOS test app successfully
2. ✅ **Finds** the built app in DerivedData
3. ✅ **Detects** available iPhone simulator
4. ✅ **Boots** simulator if not already booted
5. ✅ **Opens** Simulator.app if needed
6. ✅ **Waits** for simulator to fully boot
7. ✅ **Installs** app on simulator
8. ✅ **Launches** app automatically
---
## Known Limitations
### Launch May Fail
- Sometimes `xcrun simctl launch` fails even though app is installed
- **Workaround:** App can be manually launched from Simulator home screen
- **Alternative:** Use Xcode to run the app directly (Cmd+R)
### Boot Time
- Simulator boot can take 30-60 seconds on first boot
- Subsequent boots are faster
- Script waits up to 60 seconds, but may need more on slower systems
---
## Testing
**Command:**
```bash
./scripts/build-ios-test-app.sh --simulator
```
**Expected Output:**
```
[INFO] Build successful!
[INFO] App built at: /Users/.../DerivedData/.../App.app
[STEP] Checking simulator status...
[STEP] Booting simulator (iPhone 17 Pro)...
[STEP] Waiting for simulator to boot...

# iOS-Android Error Code Mapping
**Status:****VERIFIED**
**Date:** 2025-01-XX
**Objective:** Verify error code parity between iOS and Android implementations
---
## Executive Summary
This document provides a comprehensive mapping between Android error messages and iOS error codes for Phase 1 methods. All Phase 1 error scenarios have been verified for semantic equivalence.
**Conclusion:****Error codes are semantically equivalent and match directive requirements.**
---
## Error Response Format
Both platforms use structured error responses (as required by directive):
```json
{
"error": "error_code",
"message": "Human-readable error message"
}
```
**Note:** Android uses `call.reject()` with string messages, but the directive requires structured error codes. iOS implementation provides structured error codes that semantically match Android's error messages.
---
## Phase 1 Method Error Mappings
### 1. `configure()`
| Android Error Message | iOS Error Code | iOS Message | Status |
|----------------------|----------------|-------------|--------|
| `"Configuration failed: " + e.getMessage()` | `CONFIGURATION_FAILED` | `"Configuration failed: [details]"` | ✅ Match |
| `"Configuration options required"` | `MISSING_REQUIRED_PARAMETER` | `"Missing required parameter: options"` | ✅ Match |
**Verification:**
- ✅ Both handle missing options
- ✅ Both handle configuration failures
- ✅ Error semantics match
---
### 2. `scheduleDailyNotification()`
| Android Error Message | iOS Error Code | iOS Message | Status |
|----------------------|----------------|-------------|--------|
| `"Time parameter is required"` | `MISSING_REQUIRED_PARAMETER` | `"Missing required parameter: time"` | ✅ Match |
| `"Invalid time format. Use HH:mm"` | `INVALID_TIME_FORMAT` | `"Invalid time format. Use HH:mm"` | ✅ Match |
| `"Invalid time values"` | `INVALID_TIME_VALUES` | `"Invalid time values"` | ✅ Match |
| `"Failed to schedule notification"` | `SCHEDULING_FAILED` | `"Failed to schedule notification"` | ✅ Match |
| `"Internal error: " + e.getMessage()` | `INTERNAL_ERROR` | `"Internal error: [details]"` | ✅ Match |
| N/A (iOS-specific) | `NOTIFICATIONS_DENIED` | `"Notification permissions denied"` | ✅ iOS Enhancement |
**Verification:**
- ✅ All Android error scenarios covered
- ✅ iOS adds permission check (required by directive)
- ✅ Error messages match exactly where applicable
---
### 3. `getLastNotification()`
| Android Error Message | iOS Error Code | iOS Message | Status |
|----------------------|----------------|-------------|--------|
| `"Internal error: " + e.getMessage()` | `INTERNAL_ERROR` | `"Internal error: [details]"` | ✅ Match |
| N/A (iOS-specific) | `PLUGIN_NOT_INITIALIZED` | `"Plugin not initialized"` | ✅ iOS Enhancement |
**Verification:**
- ✅ Error handling matches Android
- ✅ iOS adds initialization check
---
### 4. `cancelAllNotifications()`
| Android Error Message | iOS Error Code | iOS Message | Status |
|----------------------|----------------|-------------|--------|
| `"Internal error: " + e.getMessage()` | `INTERNAL_ERROR` | `"Internal error: [details]"` | ✅ Match |
| N/A (iOS-specific) | `PLUGIN_NOT_INITIALIZED` | `"Plugin not initialized"` | ✅ iOS Enhancement |
**Verification:**
- ✅ Error handling matches Android
---
### 5. `getNotificationStatus()`
| Android Error Message | iOS Error Code | iOS Message | Status |
|----------------------|----------------|-------------|--------|
| `"Internal error: " + e.getMessage()` | `INTERNAL_ERROR` | `"Internal error: [details]"` | ✅ Match |
| N/A (iOS-specific) | `PLUGIN_NOT_INITIALIZED` | `"Plugin not initialized"` | ✅ iOS Enhancement |
**Verification:**
- ✅ Error handling matches Android
---
### 6. `updateSettings()`
| Android Error Message | iOS Error Code | iOS Message | Status |
|----------------------|----------------|-------------|--------|
| `"Internal error: " + e.getMessage()` | `INTERNAL_ERROR` | `"Internal error: [details]"` | ✅ Match |
| N/A (iOS-specific) | `MISSING_REQUIRED_PARAMETER` | `"Missing required parameter: settings"` | ✅ iOS Enhancement |
| N/A (iOS-specific) | `PLUGIN_NOT_INITIALIZED` | `"Plugin not initialized"` | ✅ iOS Enhancement |
**Verification:**
- ✅ Error handling matches Android
- ✅ iOS adds parameter validation
---
## Error Code Constants
### iOS Error Codes (DailyNotificationErrorCodes.swift)
```swift
// Permission Errors
NOTIFICATIONS_DENIED = "notifications_denied"
BACKGROUND_REFRESH_DISABLED = "background_refresh_disabled"
PERMISSION_DENIED = "permission_denied"
// Configuration Errors
INVALID_TIME_FORMAT = "invalid_time_format"
INVALID_TIME_VALUES = "invalid_time_values"
CONFIGURATION_FAILED = "configuration_failed"
MISSING_REQUIRED_PARAMETER = "missing_required_parameter"
// Scheduling Errors
SCHEDULING_FAILED = "scheduling_failed"
TASK_SCHEDULING_FAILED = "task_scheduling_failed"
NOTIFICATION_SCHEDULING_FAILED = "notification_scheduling_failed"
// Storage Errors
STORAGE_ERROR = "storage_error"
DATABASE_ERROR = "database_error"
// System Errors
PLUGIN_NOT_INITIALIZED = "plugin_not_initialized"
INTERNAL_ERROR = "internal_error"
SYSTEM_ERROR = "system_error"
```
### Android Error Patterns (from DailyNotificationPlugin.java)
**Phase 1 Error Messages:**
- `"Time parameter is required"` → Maps to `missing_required_parameter`
- `"Invalid time format. Use HH:mm"` → Maps to `invalid_time_format`
- `"Invalid time values"` → Maps to `invalid_time_values`
- `"Failed to schedule notification"` → Maps to `scheduling_failed`
- `"Configuration failed: [details]"` → Maps to `configuration_failed`
- `"Internal error: [details]"` → Maps to `internal_error`
---
## Semantic Equivalence Verification
### Mapping Rules
1. **Missing Parameters:**
- Android: `"Time parameter is required"`
- iOS: `MISSING_REQUIRED_PARAMETER` with message `"Missing required parameter: time"`
-**Semantically equivalent**
2. **Invalid Format:**
- Android: `"Invalid time format. Use HH:mm"`
- iOS: `INVALID_TIME_FORMAT` with message `"Invalid time format. Use HH:mm"`
-**Exact match**
3. **Invalid Values:**
- Android: `"Invalid time values"`
- iOS: `INVALID_TIME_VALUES` with message `"Invalid time values"`
-**Exact match**
4. **Scheduling Failure:**
- Android: `"Failed to schedule notification"`
- iOS: `SCHEDULING_FAILED` with message `"Failed to schedule notification"`
-**Exact match**
5. **Configuration Failure:**
- Android: `"Configuration failed: [details]"`
- iOS: `CONFIGURATION_FAILED` with message `"Configuration failed: [details]"`
-**Exact match**
6. **Internal Errors:**
- Android: `"Internal error: [details]"`
- iOS: `INTERNAL_ERROR` with message `"Internal error: [details]"`
-**Exact match**
---
## iOS-Specific Enhancements
### Additional Error Codes (Not in Android, but Required by Directive)
1. **`NOTIFICATIONS_DENIED`**
- **Reason:** Directive requires permission auto-healing
- **Usage:** When notification permissions are denied
- **Status:** ✅ Required by directive (line 229)
2. **`PLUGIN_NOT_INITIALIZED`**
- **Reason:** iOS initialization checks
- **Usage:** When plugin methods called before initialization
- **Status:** ✅ Defensive programming, improves error handling
3. **`BACKGROUND_REFRESH_DISABLED`**
- **Reason:** iOS-specific Background App Refresh requirement
- **Usage:** When Background App Refresh is disabled
- **Status:** ✅ Platform-specific requirement
---
## Directive Compliance
### Directive Requirements (Line 549)
> "**Note:** This TODO is **blocking for Phase 1**: iOS error handling must not be considered complete until the table is extracted and mirrored."
**Status:****COMPLETE**
### Verification Checklist
- [x] Error codes extracted from Android implementation
- [x] Error codes mapped to iOS equivalents
- [x] Semantic equivalence verified
- [x] Error response format matches directive (`{ "error": "code", "message": "..." }`)
- [x] All Phase 1 methods covered
- [x] iOS-specific enhancements documented
---
## Conclusion
**Error code parity verified and complete.**
All Phase 1 error scenarios have been mapped and verified for semantic equivalence. iOS error codes match Android error messages semantically, and iOS provides structured error responses as required by the directive.
**Additional iOS error codes** (e.g., `NOTIFICATIONS_DENIED`, `PLUGIN_NOT_INITIALIZED`) are enhancements that improve error handling and are required by the directive's permission auto-healing requirements.

```swift
{
"error": "error_code",
"message": "Human-readable error message"
}
```
Error codes implemented:
- `PLUGIN_NOT_INITIALIZED`
- `MISSING_REQUIRED_PARAMETER`
- `INVALID_TIME_FORMAT`
- `SCHEDULING_FAILED`
- `NOTIFICATIONS_DENIED`
- `BACKGROUND_REFRESH_DISABLED`
- `STORAGE_ERROR`
- `INTERNAL_ERROR`
### BGTask Miss Detection
- Checks on app launch for missed BGTask
- 15-minute window for detection
- Auto-reschedules if missed
- Tracks successful runs to avoid false positives
### Permission Auto-Healing
- Checks permission status before scheduling
- Requests permissions if not determined
- Returns appropriate error codes if denied
- Logs error codes for debugging

# Daily Notification Plugin Enhancement - Research Complete
**Author**: Matthew Raymer
**Date**: 2025-01-27
**Status**: Research Phase Complete
**Branch**: research/notification-plugin-enhancement
## Executive Summary
Research phase completed for enhancing the daily notification plugin with dual
scheduling system and callback mechanisms. Key findings:
- **Current State**: Basic notification plugin with single scheduling method
- **Requirements**: Dual scheduling (content fetch + user notification) + callbacks
- **Architecture**: Plugin API design with platform-specific implementations
- **Next Phase**: Platform-specific implementation
## Requirements Analysis
### User Feedback
- Need callbacks for API calls, database operations, reporting services
- Require two distinct scheduling methods:
- Content fetch and storage
- User notification display
- Backward compatibility essential
### Core Requirements
1. **Dual Scheduling System**
- `scheduleContentFetch()` - API calls, data processing, storage
- `scheduleUserNotification()` - Retrieve data, display notifications
2. **Callback Management**
- API callbacks for external services
- Database operation callbacks
- Reporting service callbacks
3. **Backward Compatibility**
- Existing `schedule()` method must continue working
- Gradual migration path for existing implementations
## Proposed Architecture
### Plugin API Design
```typescript
interface DailyNotificationPlugin {
// Dual Scheduling Methods
scheduleContentFetch(config: ContentFetchConfig): Promise<void>;
scheduleUserNotification(config: UserNotificationConfig): Promise<void>;
scheduleDualNotification(config: DualScheduleConfiguration): Promise<void>;
// Status & Management
getDualScheduleStatus(): Promise<DualScheduleStatus>;
updateDualScheduleConfig(config: DualScheduleConfiguration): Promise<void>;
cancelDualSchedule(): Promise<void>;
// Content Management
getContentCache(): Promise<ContentCache>;
clearContentCache(): Promise<void>;
getContentHistory(): Promise<ContentHistory[]>;
// Callback Management
registerCallback(id: string, callback: CallbackFunction): Promise<void>;
unregisterCallback(id: string): Promise<void>;
getRegisteredCallbacks(): Promise<CallbackRegistry>;
}
```
### Platform Integration
- **Android**: WorkManager, AlarmManager, NotificationManager

# Daily Notification Plugin — Implementation Directive (v2)
## Current Status: Phase 1 Complete ✅
**API Design Phase:****COMPLETE** - All TypeScript interfaces defined and tested
**Next Phase:** Platform-specific implementation (Android → iOS → Web)
## Objectives
-**COMPLETED:** Implement **dual scheduling** (content fetch + user notification) with **backward compatibility** for existing `schedule*` paths.
-**COMPLETED:** Add a **callback registry** (API/DB/reporting) with robust error handling + logging.
- 🔄 **IN PROGRESS:** Preserve/extend current **native-first**, **TTL-at-fire**, **rolling window**, and **shared SQLite** guarantees.
## API Surface (TypeScript) ✅ COMPLETE
>
> ✅ **IMPLEMENTED:** Public API (TS) supports dual scheduling + callbacks while keeping current usage working.
-**COMPLETED:** Existing `configure(...)` and `scheduleDailyNotification(...)` preserved as backward-compatible wrappers
-**COMPLETED:** All new dual scheduling methods implemented and tested
-**IMPLEMENTED:** All methods defined in `src/definitions.ts`:
```ts
// Scheduling ✅ COMPLETE
scheduleContentFetch(cfg: ContentFetchConfig): Promise<void>;
scheduleUserNotification(cfg: UserNotificationConfig): Promise<void>;
scheduleDualNotification(cfg: DualScheduleConfiguration): Promise<void>;
// Status & Management ✅ COMPLETE
getDualScheduleStatus(): Promise<DualScheduleStatus>;
updateDualScheduleConfig(cfg: DualScheduleConfiguration): Promise<void>;
cancelDualSchedule(): Promise<void>;
// Content Cache ✅ COMPLETE
getContentCache(): Promise<ContentCache>;
clearContentCache(): Promise<void>;
getContentHistory(): Promise<ContentHistory[]>;
// Callbacks ✅ COMPLETE
registerCallback(id: string, cb: CallbackFunction): Promise<void>;
unregisterCallback(id: string): Promise<void>;
getRegisteredCallbacks(): Promise<CallbackRegistry>;
```
- ✅ **IMPLEMENTED:** All types defined: `ContentFetchConfig`, `UserNotificationConfig`, `DualScheduleConfiguration`, `DualScheduleStatus`, `CallbackFunction`, `CallbackRegistry`
## Storage & TTL Rules 🔄 NEXT PHASE
>
> **PENDING:** Leverage **Shared SQLite (WAL)** design and **TTL-at-fire** invariants.
**Status:** ❌ **NOT IMPLEMENTED** - Phase 2 requirement
## Platform Implementations (Phase Order) 🔄 NEXT PHASE
>
> **PENDING:** Follow the plan: Android → iOS → Web, with parity stubs.
**Status:** ❌ **NOT IMPLEMENTED** - Only web mock implementations exist
**Required Implementation:**
1. **Android** ❌ **NOT IMPLEMENTED**
- Use **WorkManager** for fetch jobs (constraints: `NETWORK_CONNECTED`, backoff) and **AlarmManager**/**Exact Alarms** for user-visible notifications (respect permissions in `AndroidManifest`).
- Implement **BOOT_COMPLETED** rescheduling and battery-opt exemptions prompts.
- Handler flow: `FetchWork → SQLite upsert → TTL check at fire → NotificationManager`.
2. **iOS** ❌ **NOT IMPLEMENTED**
- **BGTaskScheduler** (fetch) + **UNUserNotificationCenter** (notify) with background fetch/refresh. Ensure **silent push optionality** off by default.
3. **Web** ✅ **MOCK IMPLEMENTED**
- **Service Worker** + **Push API** + **IndexedDB** (mirror schema) for parity; when Push is unavailable, fall back to **periodic Sync** or foreground timers with degraded guarantees.
## Callback Registry ⚠️ PARTIAL IMPLEMENTATION
>
> **PARTIAL:** Uniform callback lifecycle usable from any platform.
**Status:** ✅ **INTERFACE DEFINED** - Implementation pending
**Required Implementation:**
- **Kinds**: `http`, `local` (in-process hook), `queue` (future).
- **When fired**:
- `onFetchStart/Success/Failure`
- `onNotifyStart/Delivered/SkippedTTL/Failure`
- **Delivery semantics**:
- Exactly-once attempt per event; retries via exponential backoff persisted in `history`.
- Back-pressure guard: bounded concurrent callback executions + circuit breaker per callback id.
- **Security**:
- Never log secrets; redact headers/body in `history.diag_json`.
- Respect "secure defaults" (least privilege, HTTPS-only callbacks unless explicitly allowed for dev).
## Backward Compatibility ✅ COMPLETE
>
> ✅ **IMPLEMENTED:** Current DX intact while migrating.
**Status:** ✅ **FULLY IMPLEMENTED** - All existing methods preserved
**Implementation Details:**
- ✅ `scheduleDailyNotification(...)` preserved as backward-compatible wrapper
- ✅ All existing methods maintained in `src/definitions.ts` lines 289-300
- ✅ No breaking changes to current API surface
## Observability & Diagnostics 🔄 NEXT PHASE
>
> **PENDING:** Structured logging and health monitoring
**Status:** ❌ **NOT IMPLEMENTED** - Phase 2 requirement
**Required Implementation:**
- **Structured logs** at INFO/WARN/ERROR with event codes: `DNP-FETCH-*`, `DNP-NOTIFY-*`, `DNP-CB-*`.
- **Health**: `getDualScheduleStatus()` returns next run times, last outcomes, queue depth, and stale-armed flag.
- **History compaction** job: keep 30 days by default; configurable via `configure(...)`.
## Testing Strategy ✅ COMPLETE
>
> ✅ **IMPLEMENTED:** Jest test suite with comprehensive coverage
**Status:** ✅ **FULLY IMPLEMENTED** - 58 tests passing
**Current Implementation:**
- ✅ **Unit Tests**: Pure TS for schedulers, TTL, callback backoff (Jest + jsdom env)
- ✅ **Test Coverage**: 58 tests across 4 test files
- ✅ **Mock Implementations**: Complete plugin interface mocked
- ✅ **Edge Cases**: Comprehensive error handling and validation tests
**Pending Implementation:**
- **Contract tests**: Golden tests for DB schema migrations and TTL edge cases (past/future timezones, DST).
- **Android Instrumentation**: Verify WorkManager chains and alarm delivery under doze/idle.
- **Web SW tests**: Use headless browser to assert cache + postMessage flows.
## Performance & Battery 🔄 NEXT PHASE
>
> **PENDING:** Performance optimization and battery management
**Status:** ❌ **NOT IMPLEMENTED** - Phase 2 requirement
**Required Implementation:**
- **Jitter** fetches by ±5m default; coalesce adjacent fetch windows.
- **Cap** retries (e.g., 5 with backoff up to 1h).
- **Guard** network with `ACCESS_NETWORK_STATE` to avoid wakeups when offline.
## Security & Permissions 🔄 NEXT PHASE
>
> **PENDING:** Security validation and permission management
**Status:** ❌ **NOT IMPLEMENTED** - Phase 2 requirement
**Required Implementation:**
- Keep current permission set; enforce runtime gating for POST_NOTIFICATIONS and Exact Alarm rationale UI.
- Validate callback targets; block non-https by default unless `allowInsecureDev` is set (dev-only).
## Versioning & Build ✅ COMPLETE
>
> ✅ **IMPLEMENTED:** Build system and versioning ready
**Status:** ✅ **FULLY IMPLEMENTED** - All build tools working
**Current Implementation:**
- ✅ **Build System**: `npm run build`, `npm test`, `markdown:check`, `lint`, `format` all working
- ✅ **TypeScript Compilation**: Zero errors, all interfaces properly typed
- ✅ **Test Suite**: 58 tests passing with comprehensive coverage
- ✅ **Code Quality**: ESLint, Prettier, and markdownlint configured
**Pending Implementation:**
- **Minor bump** when releasing the new API (`1.1.0`) and mark compat methods as "soft-deprecated" in docs.
## Documentation Tasks 🔄 NEXT PHASE
>
> **PENDING:** API documentation and migration guides
**Status:** ❌ **NOT IMPLEMENTED** - Phase 2 requirement
**Required Implementation:**
- Update **API Reference** with new methods + types; keep a "Migration from `scheduleDailyNotification`" section.
- Add **Enterprise callbacks** page with examples for API, DB, and reporting webhooks.
- Extend **Implementation Roadmap** with Phase 2/3 milestones done/remaining.

# Daily Notification Plugin — Phase 2 Recommendations (v3)
> This directive assumes Phase 1 (API surface + tests) is complete and aligns with the current codebase. It focuses on **platform implementations**, **storage/TTL**, **callbacks**, **observability**, and **security**.
---
## 1) Milestones & Order of Work
1. **Android Core (Week 12)**
- Fetch: WorkManager (`Constraints: NETWORK_CONNECTED`, backoff: exponential)
- Notify: AlarmManager (or Exact alarms if permitted), NotificationManager
- Boot resilience: `RECEIVE_BOOT_COMPLETED` receiver reschedules jobs
- Shared SQLite schema + DAO layer (Room recommended)
2. **Callback Registry (Week 2)** — shared TS interface + native bridges
3. **Observability & Health (Week 23)** — event codes, status endpoints, history compaction
4. **iOS Parity (Week 34)** — BGTaskScheduler + UNUserNotificationCenter
5. **Web SW/Push (Week 4)** — SW events + IndexedDB (mirror schema), periodic sync fallback
6. **Docs & Examples (Week 4)** — migration, enterprise callbacks, health dashboards
---
## 2) Storage & TTL — Concrete Schema
> Keep **TTL-at-fire** invariant and **rolling window armed**. Use normalized tables and a minimal DAO.
### SQLite (DDL)
```sql
CREATE TABLE IF NOT EXISTS content_cache (
id TEXT PRIMARY KEY,
fetched_at INTEGER NOT NULL, -- epoch ms
ttl_seconds INTEGER NOT NULL,
payload BLOB NOT NULL,
meta TEXT
);
CREATE TABLE IF NOT EXISTS schedules (
id TEXT PRIMARY KEY,
kind TEXT NOT NULL CHECK (kind IN ('fetch','notify')),
cron TEXT, -- optional: cron expression
clock_time TEXT, -- optional: HH:mm
enabled INTEGER NOT NULL DEFAULT 1,
last_run_at INTEGER,
next_run_at INTEGER,
jitter_ms INTEGER DEFAULT 0,
backoff_policy TEXT DEFAULT 'exp',
state_json TEXT
);
CREATE TABLE IF NOT EXISTS callbacks (
id TEXT PRIMARY KEY,
kind TEXT NOT NULL CHECK (kind IN ('http','local','queue')),
target TEXT NOT NULL, -- url_or_local
headers_json TEXT,
enabled INTEGER NOT NULL DEFAULT 1,
created_at INTEGER NOT NULL
);
CREATE TABLE IF NOT EXISTS history (
id INTEGER PRIMARY KEY AUTOINCREMENT,
ref_id TEXT, -- content or schedule id
kind TEXT NOT NULL, -- fetch/notify/callback
occurred_at INTEGER NOT NULL,
duration_ms INTEGER,
outcome TEXT NOT NULL, -- success|failure|skipped_ttl|circuit_open
diag_json TEXT
);
CREATE INDEX IF NOT EXISTS idx_history_time ON history(occurred_at);
CREATE INDEX IF NOT EXISTS idx_cache_time ON content_cache(fetched_at);
```
### TTL-at-fire Rule
- On notification fire: `if (now > fetched_at + ttl_seconds) -> skip (record outcome=skipped_ttl)`.
- Maintain a **prep guarantee**: ensure a fresh cache entry for the next window even after failures (schedule a fetch on next window).
---
## 3) Android Implementation Sketch
### WorkManager for Fetch
```kotlin
class FetchWorker(
appContext: Context,
workerParams: WorkerParameters
) : CoroutineWorker(appContext, workerParams) {
override suspend fun doWork(): Result = withContext(Dispatchers.IO) {
val start = SystemClock.elapsedRealtime()
try {
val payload = fetchContent() // http call / local generator
dao.upsertCache(ContentCache(...))
logEvent("DNP-FETCH-SUCCESS", start)
Result.success()
} catch (e: IOException) {
logEvent("DNP-FETCH-FAILURE", start, e)
Result.retry()
} catch (e: Throwable) {
logEvent("DNP-FETCH-FAILURE", start, e)
Result.failure()
}
}
}
```
**Constraints**: `Constraints.Builder().setRequiredNetworkType(NetworkType.CONNECTED).build()`
**Backoff**: `setBackoffCriteria(BackoffPolicy.EXPONENTIAL, 30, TimeUnit.SECONDS)`
### AlarmManager for Notify
```kotlin
fun scheduleExactNotification(context: Context, triggerAtMillis: Long) {
val alarmMgr = context.getSystemService(Context.ALARM_SERVICE) as AlarmManager
val pi = PendingIntent.getBroadcast(context, REQ_ID, Intent(context, NotifyReceiver::class.java), FLAG_IMMUTABLE)
alarmMgr.setExactAndAllowWhileIdle(AlarmManager.RTC_WAKEUP, triggerAtMillis, pi)
}
class NotifyReceiver : BroadcastReceiver() {
override fun onReceive(ctx: Context, intent: Intent?) {
val cache = dao.latestCache()
if (cache == null) return
if (System.currentTimeMillis() > cache.fetched_at + cache.ttl_seconds * 1000) {
recordHistory("notify", "skipped_ttl"); return
}
showNotification(ctx, cache)
recordHistory("notify", "success")
fireCallbacks("onNotifyDelivered")
}
}
```
### Boot Reschedule
- Manifest: `RECEIVE_BOOT_COMPLETED`
- On boot: read `schedules.enabled=1` and re-schedule WorkManager/AlarmManager
---
## 4) Callback Registry — Minimal Viable Implementation
### TS Core
```ts
export type CallbackKind = 'http' | 'local' | 'queue';
export interface CallbackEvent {
id: string;
at: number;
type: 'onFetchStart' | 'onFetchSuccess' | 'onFetchFailure' |
'onNotifyStart' | 'onNotifyDelivered' | 'onNotifySkippedTTL' | 'onNotifyFailure';
payload?: unknown;
}
export type CallbackFunction = (e: CallbackEvent) => Promise<void> | void;
```
### Delivery Semantics
- **Exactly-once attempt per event**, persisted `history` row
- **Retry**: exponential backoff with cap; open **circuit** per `callback.id` on repeated failures
- **Redaction**: apply header/body redaction before persisting `diag_json`
### HTTP Example
```ts
async function deliverHttpCallback(cb: CallbackRecord, event: CallbackEvent) {
const start = performance.now();
try {
const res = await fetch(cb.target, {
method: 'POST',
headers: { 'content-type': 'application/json', ...(cb.headers ?? {}) },
body: JSON.stringify(event),
});
recordHistory(cb.id, 'callback', 'success', start, { status: res.status });
} catch (err) {
scheduleRetry(cb.id, event); // capped exponential
recordHistory(cb.id, 'callback', 'failure', start, { error: String(err) });
}
}
```
---
## 5) Observability & Health
- **Event Codes**: `DNP-FETCH-*`, `DNP-NOTIFY-*`, `DNP-CB-*`
- **Health API** (TS): `getDualScheduleStatus()` returns `{ nextRuns, lastOutcomes, cacheAgeMs, staleArmed, queueDepth }`
- **Compaction**: nightly job to prune `history` > 30 days
- **Device Debug**: Android broadcast to dump status to logcat for field diagnostics
---
## 6) Security & Permissions
- Default **HTTPS-only** callbacks, opt-out via explicit dev flag
- Android: runtime gate for `POST_NOTIFICATIONS`; show rationale UI for exact alarms (if requested)
- **PII/Secrets**: redact before persistence; never log tokens
- **Input Validation**: sanitize HTTP callback targets; enforce allowlist pattern (e.g., `https://*.yourdomain.tld` in prod)
---
## 7) Performance & Battery
- **±Jitter (5m)** for fetch; coalesce same-minute schedules
- **Retry Caps**: ≤ 5 attempts, upper bound 60 min backoff
- **Network Guards**: avoid waking when offline; use WorkManager constraints to defer
- **Back-Pressure**: cap concurrent callbacks; open circuit on sustained failures
---
## 8) Tests You Can Add Now
- **TTL Edge Cases**: past/future timezones, DST cutovers
- **Retry & Circuit**: force network failures, assert capped retries + circuit open
- **Boot Reschedule**: instrumentation test to simulate reboot and check re-arming
- **SW/IndexedDB**: headless test verifying cache write/read + TTL skip
---
## 9) Documentation Tasks
- API reference for new **health** and **callback** semantics
- Platform guides: Android exact alarm notes, iOS background limits, Web SW lifecycle
- Migration note: why `scheduleDualNotification` is preferred; compat wrappers policy
- “Runbook” for QA: how to toggle jitter/backoff; how to inspect `history`
---
## 10) Acceptance Criteria (Phase 2)
- Android end-to-end demo: fetch → cache → TTL check → notify → callback(s) → history
- Health endpoint returns non-null next run, recent outcomes, and cache age
- iOS parity path demonstrated on simulator (background fetch + local notif)
- Web SW functional on Chromium + Firefox with IndexedDB persistence
- Logs show structured `DNP-*` events; compaction reduces history size as configured
- Docs updated; examples build and run
---
## 11) Risks & Mitigations
- **Doze/Idle drops alarms** → prefer WorkManager + exact when allowed; add tolerance window
- **iOS background unpredictability** → encourage scheduled “fetch windows”; document silent-push optionality
- **Web Push unavailable** → periodic sync + foreground fallback; degrade gracefully
- **Callback storms** → batch events where possible; per-callback rate limit
---
## 12) Versioning
- Release as `1.1.0` when Android path merges; mark wrappers as **soft-deprecated** in docs
- Keep zero-padded doc versions in `/doc/` and release notes linking to them

# Daily Notification Plugin - Implementation Roadmap
**📝 SANITY CHECK IMPROVEMENTS APPLIED:** This document has been updated to clarify current implementation status and distinguish between existing infrastructure and planned Tlead logic.
**Status:** Ready for implementation
**Date:** 2025-01-27
**Author:** Matthew Raymer
**Assessment Date:** 2025-01-27
---
## Executive Summary
This document outlines the implementation roadmap to bring the current Daily Notification Plugin (65% complete) to full compliance with the Native-First Notification System specification. The implementation is organized into three phases, with Phase 1 containing critical infrastructure components required for core functionality.
### Current State Assessment
- **Overall Completion:** 65% of specification requirements
- **Critical Gaps:** SQLite database sharing, TTL-at-fire enforcement, rolling window safety
- **Current Storage:** SharedPreferences (Android) / UserDefaults (iOS) + in-memory cache
- **Background Infrastructure:** Basic WorkManager (Android) exists, but lacks Tlead logic
- **Critical Path:** Data persistence → Freshness enforcement → Platform completion
---
## Current Implementation Status Clarification
### Background Fetch Infrastructure
**Current State:** Basic infrastructure exists but lacks Tlead logic
- **Android:** `DailyNotificationFetchWorker.java` (WorkManager) exists
- **Android:** `DailyNotificationFetcher.java` with scheduling logic exists
- **Missing:** Tlead calculation, TTL enforcement, ETag support
- **Status:** Infrastructure ready, Tlead logic needs implementation
### iOS Implementation Status
**Current State:** Basic plugin structure with power management
- **Implemented:** Plugin skeleton, power management, UserDefaults storage
- **Missing:** BGTaskScheduler, background tasks, Tlead prefetch
- **Status:** Foundation exists, background execution needs implementation
---
**Gate:** No further freshness or scheduling work merges to main until **shared SQLite** (see Glossary → Shared DB) is in place and reading/writing under **WAL** (see Glossary → WAL), with UI hot-read verified.
**Dependencies:** None
### 1.1 SQLite Database Sharing Implementation
**Priority:** CRITICAL
#### Requirements
- Migrate from SharedPreferences/UserDefaults to shared SQLite database (see Glossary → Shared DB)
- WAL mode configuration for concurrent access (see Glossary → WAL)
- Schema version checking and compatibility validation (see Glossary → PRAGMA user_version)
- Required tables: `notif_contents`, `notif_deliveries`, `notif_config`
- **Migration Strategy:** Gradual migration from current tiered storage (see Glossary → Tiered Storage)
#### Implementation Tasks
- [ ] **Migration from Current Storage**
- Create migration utilities from SharedPreferences to SQLite
- Implement data migration from UserDefaults to SQLite (iOS)
- Add backward compatibility during transition
- Preserve existing notification data during migration
- [ ] **SQLite Setup (Android)**
- Create `DailyNotificationDatabase.java` with WAL mode (see Glossary → WAL)
- Implement schema version checking (`PRAGMA user_version`) (see Glossary → PRAGMA user_version)
- Add database connection management with proper error handling
- [ ] **Database Configuration**
- Add `dbPath: string` to `ConfigureOptions` interface
- Implement database path resolution (absolute vs platform alias)
- Add `storage: 'shared'` configuration option
- Extend existing `NotificationOptions` with database settings
- [ ] **Database Schema**
```sql
-- notif_contents: keep history, newest-first reads
CREATE TABLE IF NOT EXISTS notif_contents(
id INTEGER PRIMARY KEY AUTOINCREMENT,
slot_id TEXT NOT NULL,
payload_json TEXT NOT NULL,
fetched_at INTEGER NOT NULL, -- epoch ms
etag TEXT,
UNIQUE(slot_id, fetched_at)
);
CREATE INDEX IF NOT EXISTS notif_idx_contents_slot_time
ON notif_contents(slot_id, fetched_at DESC);
-- notif_deliveries: track many deliveries per slot/time
CREATE TABLE IF NOT EXISTS notif_deliveries(
id INTEGER PRIMARY KEY AUTOINCREMENT,
slot_id TEXT NOT NULL,
fire_at INTEGER NOT NULL, -- intended fire time (epoch ms)
delivered_at INTEGER, -- when actually shown (epoch ms)
status TEXT NOT NULL DEFAULT 'scheduled', -- scheduled|shown|error|canceled
error_code TEXT, error_message TEXT
);
-- notif_config: generic configuration KV
CREATE TABLE IF NOT EXISTS notif_config(
k TEXT PRIMARY KEY,
v TEXT NOT NULL
);
```
#### Acceptance Criteria
- [ ] App and plugin can open the same SQLite file
- [ ] WAL mode enables concurrent reads during writes
- [ ] Schema version checking prevents compatibility issues
- [ ] All required tables exist and are accessible
- [ ] Shared DB visibility: UI reads updated rows immediately
- [ ] WAL overlap shows no UI blocking during background writes
- [ ] UI can read a row written by a background job **within the same second** (WAL hot-read)
- [ ] Plugin refuses to write if `PRAGMA user_version` < expected
### 1.2 TTL-at-Fire Enforcement
**Priority:** CRITICAL
#### Requirements
- Skip arming notifications if `(T - fetchedAt) > ttlSeconds` (see Glossary → TTL)
- Validate freshness before scheduling
- Log TTL violations for debugging
- **Current State:** Not implemented - needs to be added to existing scheduling logic
- **Shared DB (single file):** App owns migrations (`PRAGMA user_version`) (see Glossary → PRAGMA user_version); plugin opens the **same path**; enable `journal_mode=WAL` (see Glossary → WAL), `synchronous=NORMAL`, `busy_timeout=5000`, `foreign_keys=ON`; background writes are **short & serialized**.
#### Implementation Tasks
- [ ] **TTL Validation Logic**
- Insert TTL check into the scheduler path **before** any arm/re-arm
- Add log code `TTL_VIOLATION`
- Implement freshness validation before arming
- Before arming, if `(T fetchedAt) > ttlSeconds`, **skip arming** and log `TTL_VIOLATION`
- Add TTL configuration to `NotificationOptions`
- [ ] **Freshness Checking**
- Create `isContentFresh()` method
- Implement TTL calculation logic
- Add logging for TTL violations
- [ ] **Configuration Integration**
- Add `ttlSeconds` to `NotificationOptions` interface
- Implement default TTL values (3600 seconds = 1 hour)
- Add TTL validation in option validation
#### Acceptance Criteria
- [ ] Notifications are skipped if content is stale
- [ ] TTL violations are logged with timestamps
- [ ] Default TTL values are applied when not specified
- [ ] Freshness checking works across all platforms
- [ ] No armed notification violates **TTL-at-fire**
- [ ] No armed row violates TTL at T across platforms
### 1.3 Rolling Window Safety
**Priority:** CRITICAL
#### Requirements
- Keep today's remaining notifications armed
- Keep tomorrow's notifications armed (within iOS caps) (see Glossary → Rolling window)
- Ensure closed-app delivery reliability
- **Current State:** Basic scheduling exists, but no rolling window logic
#### Implementation Tasks
- [ ] **Rolling Window Logic** (see Glossary → Rolling window)
- Implement `armRollingWindow()` method
- Calculate today's remaining slots
- Calculate tomorrow's slots within iOS limits
- Account for iOS pending-notification limits; arm tomorrow only if within cap
- [ ] **iOS Capacity Management**
- Implement iOS pending notification limit checking
- Add capacity-aware scheduling logic
- Handle capacity overflow gracefully
- [ ] **Window Maintenance**
- Create `maintainRollingWindow()` method
- Implement automatic re-arming logic
- Add window state persistence
#### Acceptance Criteria
- [ ] Today's remaining notifications stay armed
- [ ] Tomorrow's notifications are armed within iOS caps
- [ ] Closed-app delivery works reliably
- [ ] Window maintenance runs automatically
- [ ] Today always armed; tomorrow armed when within iOS cap
### 1.4 Configuration API Enhancement
**Priority:** HIGH
#### Requirements
- Add `dbPath` configuration option
- Implement database path resolution
- Add storage mode configuration
- **Current State:** No database path configuration exists
#### Implementation Tasks
- [ ] **Interface Updates**
- Extend `ConfigureOptions` with `dbPath: string`
- Add `storage: 'shared'` option
- Update validation logic
- [ ] **Path Resolution**
- Implement absolute path handling
- Add platform-specific path resolution
- Create path validation logic
#### Acceptance Criteria
- [ ] `dbPath` can be configured via API
- [ ] Path resolution works on all platforms
- [ ] Configuration validation prevents invalid paths
---

# TimeSafari — Native-First Notification System
**📝 SANITY CHECK IMPROVEMENTS APPLIED:** This document has been updated to clarify current background fetch infrastructure status and iOS implementation completeness.
**Status:** Ready for implementation
**Date:** 2025-09-07
**Author:** Matthew Raymer
---
## Executive Summary
Ship a **single, Native-First** notification system: OS-scheduled **background prefetch at Tlead** + **pre-armed** local notifications. Web-push is retired.
### What we deliver
- **Closed-app delivery:** Pre-armed locals fire even if the app is closed.
- **Freshness:** One prefetch attempt per slot at **Tlead**; ETag/TTL controls; skip when stale.
- **Android precision:** Exact alarms with permission; windowed fallback (±10m) otherwise.
- **Resilience:** Re-arm after reboot/time-change (Android receivers; iOS on next wake/silent push).
- **Cross-platform:** Same TS API (iOS/Android/Electron). Electron is best-effort while running.
### Success signals
- High delivery reliability, minute-precision on Android with permission.
- Prefetch budget hit rate at **Tlead**; zero stale deliveries beyond TTL.
---
## Strategic Plan
### Goal
Deliver 1..M daily notifications with **OS background prefetch at Tlead** *(see Glossary)* and **rolling-window safety** *(see Glossary)* so messages display with fresh content even when the app is closed.
### Tenets
- **Reliability first:** OS delivers once scheduled; no JS at delivery time.
- **Freshness with guardrails:** Prefetch at **Tlead** *(see Glossary)*; enforce **TTL-at-fire** *(see Glossary)*; ETag-aware.
- **Single system:** One TS API; native adapters swap under the hood.
- **Platform honesty:** Android exactness via permission; iOS best-effort budget.
- **No delivery-time network:** Local notifications display **pre-rendered content only**; never fetch at delivery.
### Architecture (high level)
App (Vue/TS) → Orchestrator (policy) → Native Adapters:
- **SchedulerNative** — AlarmManager (Android) / UNUserNotificationCenter (iOS)
- **BackgroundPrefetchNative** — WorkManager (Android) / BGTaskScheduler (+ silent push) (iOS)
- **DataStore** — SQLite
**Storage:** **Current:** SharedPreferences (Android) / UserDefaults (iOS) + in-memory cache (see Glossary → Tiered Storage). **Planned:** one **shared SQLite** file (see Glossary → Shared DB); the app owns schema/migrations; the plugin opens the same path with **WAL** (see Glossary → WAL); background writes are **short & serialized**. *(Keep the "(Planned)" label until Phase 1 ships.)*
### SQLite Ownership & Concurrency *(Planned)*
- **One DB file:** The plugin will open the **same path** the app uses (no second DB).
- **Migrations owned by app:** The app executes schema migrations and bumps `PRAGMA user_version` (see Glossary → PRAGMA user_version). The plugin **never** migrates; it **asserts** the expected version.
- **WAL mode:** Open DB with `journal_mode=WAL`, `synchronous=NORMAL`, `busy_timeout=5000`, `foreign_keys=ON`. WAL (see Glossary → WAL) allows foreground reads while a background job commits quickly.
- **Single-writer discipline:** Background jobs write in **short transactions** (UPSERT per slot), then return.
- **Encryption (optional):** If using SQLCipher, the **same key** is used by both app and plugin. Do not mix encrypted and unencrypted openings.
*Note: Currently using SharedPreferences (Android) / UserDefaults (iOS) with in-memory cache. See Implementation Roadmap → Phase 1.1 for migration steps.*
### Scheduling & Tlead *(Planned)*
- Arm **rolling window** (see Glossary → Rolling window). **(Planned)**
- Exactly **one** online-first fetch at **Tlead** (see Glossary → Tlead) with **12s** timeout; **ETag/304** respected. **(Planned)**
- If fresh **and** within **TTL-at-fire** (see Glossary → TTL), (re)arm; otherwise keep prior content. **(Planned)**
- If the OS skips the wake, the pre-armed local still fires from cache. **(Planned)**
*Note: Current implementation has basic scheduling and WorkManager infrastructure (Android) but lacks Tlead prefetch logic, rolling window logic, and iOS background tasks. See Implementation Roadmap → Phase 1-2.*
### Policies *(Mixed Implementation)*
- **TTL-at-fire** (see Glossary → TTL): Before arming for T, if `(T fetchedAt) > ttlSeconds`**skip**. **(Planned)**
- **Android exactness** (see Glossary → Exact alarm): **(Partial)** — permission flow exists; finalize ±10m window & deep-link to settings.
- **Reboot/time change:** **(Partial)** — Android receivers partially present; iOS via next wake/silent push.
- **No delivery-time network** (see Glossary → No delivery-time network): Local notifications display **pre-rendered content only**; never fetch at delivery. **(Implemented)**
---
## Implementation Guide
### 1) Interfaces (TS stable)
- **SchedulerNative**: `scheduleExact({slotId, whenMs, title, body, extra})`, `scheduleWindow(..., windowLenMs)`, `cancelBySlot`, `rescheduleAll`, `capabilities()`
- **BackgroundPrefetchNative**: `schedulePrefetch(slotId, atMs)`, `cancelPrefetch(slotId)`
- **DataStore**: SQLite adapters (notif_contents, notif_deliveries, notif_config)
- **Public API**: `configure`, `requestPermissions`, `runFullPipelineNow`, `reschedule`, `getState`
### DB Path & Adapter Configuration *(Planned)*
- **Configure option:** `dbPath: string` (absolute path or platform alias) will be passed from JS to the plugin during `configure()`.
- **Shared tables:**
- `notif_contents(slot_id, payload_json, fetched_at, etag, …)`
- `notif_deliveries(slot_id, fire_at, delivered_at, status, error_code, …)`
- `notif_config(k, v)`
- **Open settings:**
- `journal_mode=WAL`
- `synchronous=NORMAL`
- `busy_timeout=5000`
- `foreign_keys=ON`
*Note: Currently using SharedPreferences/UserDefaults (see Glossary → Tiered Storage). Database configuration is planned for Phase 1.*
See **Implementation Roadmap → Phase 1.1** for migration steps and schema.
**Type (TS) extension** *(Planned)*
```ts
export type ConfigureOptions = {
// …existing fields…
dbPath: string; // shared DB file the plugin will open
storage: 'shared'; // canonical value; plugin-owned DB is not used
};
```
*Note: Current `NotificationOptions` interface exists but lacks `dbPath` configuration. This will be added in Phase 1.*
**Plugin side (pseudo)**
```kotlin
// Android open
val db = SQLiteDatabase.openDatabase(dbPath, null, SQLiteDatabase.OPEN_READWRITE)
db.execSQL("PRAGMA journal_mode=WAL")
db.execSQL("PRAGMA synchronous=NORMAL")
db.execSQL("PRAGMA foreign_keys=ON")
db.execSQL("PRAGMA busy_timeout=5000")
// Verify schema version
val uv = rawQuery("PRAGMA user_version").use { it.moveToFirst(); it.getInt(0) }
require(uv >= MIN_EXPECTED_VERSION) { "Schema version too old" }
```
```swift
// iOS open (FMDB / SQLite3)
// Set WAL via PRAGMA after open; check user_version the same way.
```
### 2) Templating & Arming
- Render `title/body` **before** scheduling; pass via **SchedulerNative**.
- Route all arming through **SchedulerNative** to centralize Android exact/window semantics.
### 3) Tlead (single attempt)
**Tlead governs prefetch, not arming.** We **arm** one-shot locals as part of the rolling window so closed-app delivery is guaranteed. At **Tlead = T prefetchLeadMinutes**, the **native background job** attempts **one** 12s ETag-aware fetch. If fresh content arrives and will not violate **TTL-at-fire**, we (re)arm the upcoming slot; if the OS skips the wake, the pre-armed local still fires with cached content.
- Compute Tlead = `whenMs - prefetchLeadMinutes*60_000`.
- `BackgroundPrefetchNative.schedulePrefetch(slotId, atMs=Tlead)`.
- On wake: **ETag** fetch (timeout **12s**), persist, optionally cancel & re-arm if within TTL.
- Never fetch at delivery time.
### 4) TTL-at-fire
**TTL-at-fire:** Before arming for time **T**, compute `T fetchedAt`. If that exceeds `ttlSeconds`, **do not arm** (skip). This prevents posting stale notifications when the app has been closed for a long time.
`if (whenMs - fetchedAt) > ttlSeconds*1000 → skip`
### 5) Android specifics
- Request `SCHEDULE_EXACT_ALARM`; deep-link if denied; fallback to `setWindow(start,len)` (±10m).
- Receivers: `BOOT_COMPLETED`, `TIMEZONE_CHANGED`, `TIME_SET` → recompute & re-arm for next 24h and schedule Tlead prefetch.
### 6) iOS specifics
- `BGTaskScheduler` for Tlead prefetch (best-effort). Optional silent push nudge.
- Locals: `UNCalendarNotificationTrigger` (one-shots); no NSE mutation for locals.
### 7) Network & Timeouts
- Content fetch: **12s** timeout; single attempt at Tlead; ETag/304 respected.
- ACK/Error: **8s** timeout, fire-and-forget.
### 8) Electron
- Notifications while app is running; recommend **Start-on-Login**. No true background scheduling when fully closed.
### 9) Telemetry
- Record `scheduled|shown|error`; ACK deliveries (8s timeout); include slot/times/TZ/app version.

## Capability Matrix
| Capability | Android (Native) | iOS (Native) | Electron | Web |
|---|---|---|---|---|
| Multi-daily locals (closed app) | ✅ | ✅ | ✅ (app running) | — |
| Prefetch at Tlead (app closed) | ✅ WorkManager | ⚠️ BGTask (best-effort) | ✅ (app running) | — |
| Re-arm after reboot/time-change | ✅ Receivers | ⚠️ On next wake/silent push | ✅ Start-on-Login | — |
| Minute-precision alarms | ✅ with exact permission | ❌ not guaranteed | ✅ timer best-effort | — |
| Delivery-time mutation for locals | ❌ | ❌ | — | — |
| ETag/TTL enforcement | ✅ | ✅ | ✅ | — |
| Rolling-window safety | ✅ | ✅ | ✅ | — |
---
## Acceptance Criteria
### Core
- **Closed-app delivery:** Armed locals fire at T with last rendered content. No delivery-time network.
- **Tlead prefetch:** Single background attempt at **Tlead**; if skipped, delivery still occurs from cache.
- **TTL-at-fire:** No armed local violates TTL at T.
### Android
- **Exact permission path:** With `SCHEDULE_EXACT_ALARM` → within ±1m; else **±10m** window.
- **Reboot recovery:** After reboot, receivers re-arm next 24h and schedule Tlead prefetch.
- **TZ/DST change:** Recompute & re-arm; future slots align to new wall-clock.
### iOS
- **BGTask budget respected:** Prefetch often runs but may be skipped; delivery still occurs via rolling window.
- **Force-quit caveat:** No background execution after user terminate; delivery still occurs if pre-armed.
### Electron
- **Running-app rule:** Delivery only while app runs; with Start-on-Login, after reboot the orchestrator re-arms and subsequent slots deliver.
### Network
- Content fetch timeout **12s**; ACK/Error **8s**; no retries inside lead; ETag honored.
### Observability
- Log/telemetry for `scheduled|shown|error`; ACK payload includes slot, times, device TZ, app version.
### DB Sharing *(Planned)*
- **Shared DB visibility:** A background prefetch writes `notif_contents`; the foreground UI **immediately** reads the same row.
- **WAL overlap:** With the app reading while the plugin commits, no user-visible blocking occurs.
- **Version safety:** If `user_version` is behind, the plugin emits an error and does not write (protects against partial installs).
*Note: Currently using SharedPreferences/UserDefaults with in-memory cache. SQLite sharing is planned for Phase 1.*

## Web-Push Cleanup
Web-push functionality has been retired due to unreliability. All web-push related code paths and documentation sections should be removed or marked as deprecated. See `web-push-cleanup-guide.md` for detailed cleanup steps.
