+# TimeSafari Notifications — LLM Implementation Directive (v2.0)
+_Last updated: August 12, 2025_
+
+## 0) Role & Objective
+**You are the implementation LLM.** Build an **offline-first daily notifications system** for Android (Kotlin) and iOS (Swift) that **prefetches -> caches -> schedules -> displays** content **without requiring network at display time**. Favor **reliability over richness**.
+
+## 1) Golden Rules
+1. **Follow the pipeline:** **Prefetch → Cache → Schedule → Display.**
+2. **Never depend on network at display time.** All assets must be local.
+3. **Design for failure.** Always have a last-known-good and an emergency fallback.
+4. **Keep content scannable (<3s), single message, actionable.**
+5. **Measure everything** (fetch success, delivery, engagement, stale usage).
+6. **Minimize battery impact** and respect platform limitations and user settings.
+7. **Ask only when needed:** if a required input is missing, use the defaults below; otherwise proceed.
+
+## 2) Default Assumptions (use unless overridden)
+- **Product mode:** Lightweight Daily Updates (text + emoji) with option to extend to media later.
+- **Fetch size:** 1–2 KB JSON daily.
+- **User schedule default:** 07:30 local time, daily.
+- **Quiet hours:** None (app-level quiet hours supported but disabled by default).
+- **Analytics:** Local log + pluggable uploader (no-op by default).
+
+## 3) Deliverables
+Produce the following artifacts:
+
+### Android (Kotlin)
+- `:core`: models, storage, metrics, fallback manager.
+- `:data`: fetchers (WorkManager), mappers, cache policy.
+- `:notify`: scheduler (AlarmManager), receiver, channels.
+- App manifest entries & permissions.
+- Unit tests for fallback, scheduling, metrics.
+- README with battery optimization instructions (OEMs).
+
+### iOS (Swift)
+- `NotificationKit`: models, storage, metrics, fallback manager.
+- BGTaskScheduler registration + handler.
+- UNUserNotificationCenter scheduling + categories + attachments.
+- Unit tests for fallback, scheduling, metrics.
+- README with Background App Refresh caveats + Focus/Summary notes.
+
+## 4) Permissions & Required Setup
+### Android Manifest
+```xml
+<uses-permission android:name="android.permission.INTERNET" />
+<uses-permission android:name="android.permission.POST_NOTIFICATIONS" />
+<uses-permission android:name="android.permission/SCHEDULE_EXACT_ALARM" />
+<uses-permission android:name="android.permission.WAKE_LOCK" />
+```
+- Create a high-importance **NotificationChannel** `timesafari.daily`.
+- If **SCHEDULE_EXACT_ALARM** denied on Android 12+, auto-fallback to inexact.
+
+### iOS App Setup (AppDelegate / SceneDelegate)
+- Register `BGTaskScheduler` with ID `com.timesafari.daily-fetch`.
+- Request alerts, sound, badge via `UNUserNotificationCenter`.
+- Create category `DAILY_UPDATE` with a primary `View` action.
+- Ensure Background Modes: **Background fetch**, **Remote notifications** (optional for future push).
+
+## 5) Data Model (keep minimal, versioned)
+### Canonical Schema (language-agnostic)
+```
+NotificationContent v1
+- id: string (uuid)
+- title: string
+- body: string (plain text; may include simple emoji)
+- scheduledTime: epoch millis (client-local target)
+- mediaUrl: string? (for future; must be mirrored to local path before use)
+- fetchTime: epoch millis
+```
+### Kotlin
+```kotlin
+@Entity
+data class NotificationContent(
+    @PrimaryKey val id: String,
+    val title: String,
+    val body: String,
+    val scheduledTime: Long,
+    val mediaUrl: String?,
+    val fetchTime: Long
+)
+```
+### Swift
+```swift
+struct NotificationContent: Codable {
+    let id: String
+    let title: String
+    let body: String
+    let scheduledTime: TimeInterval
+    let mediaUrl: String?
+    let fetchTime: TimeInterval
+}
+```
+
+## 6) Storage Layers
+**Tier 1: Key-Value (quick)** — next payload, last fetch timestamp, user prefs.  
+**Tier 2: DB (structured)** — history, media metadata, analytics events.  
+**Tier 3: Files (large assets)** — images/audio; LRU cache & quotas.
+
+- Android: SharedPreferences/DataStore + Room + `context.cacheDir/notifications/`  
+- iOS: UserDefaults + Core Data/SQLite + `Library/Caches/notifications/`
+
+## 7) Background Execution
+### Android — WorkManager
+- Periodic daily work with constraints (CONNECTED network).  
+- Total time budget ~10m; use **timeouts** (e.g., fetch ≤30s, overall ≤8m).  
+- On exception/timeout: **schedule from cache**; then `Result.success()` or `Result.retry()` per policy.
+
+### iOS — BGTaskScheduler
+- `BGAppRefreshTask` with aggressive time budgeting (10–30s typical).  
+- Submit next request immediately at start of handler.  
+- Set `expirationHandler` first; cancel tasks cleanly; **fallback to cache** on failure.
+
+## 8) Scheduling & Display
+### Android
+- Prefer `AlarmManager.setExactAndAllowWhileIdle()` if permitted; else inexact.  
+- Receiver builds notification using **BigTextStyle** for long bodies.  
+- Limit actions to ≤3; default: `View` (foreground intent).
+
+### iOS
+- `UNCalendarNotificationTrigger` repeating at preferred time.  
+- Category `DAILY_UPDATE` with `View` action.  
+- Media attachments **only if local**; otherwise skip gracefully.
+
+## 9) Fallback Hierarchy (must implement)
+1. **Foreground prefetch path** if app is open.  
+2. **Background fetch** with short network timeout.  
+3. **Last good cache** (annotate staleness: “as of X”).  
+4. **Emergency phrases** (rotate from static list).
+
+Provide helper:
+- `withStaleMarker(content) -> content'` appends age label (e.g., “from 3h ago”).
+
+## 10) Failure Matrix & Responses
+| Scenario | Detect | Action |
+|---|---|---|
+| No network / timeout | Exceptions / status | Use last-good; schedule |
+| Invalid JSON | Parse error | Use emergency content; log |
+| Storage full | Write error | Evict old; retry minimal payload |
+| Notifications disabled | OS state | In-app education screen |
+| Background killed | Gaps in execution | Catch-up next foreground open |
+
+## 11) Metrics (local first; uploader optional)
+Track per attempt:
+```
+NotificationMetrics v1
+- scheduledTime, actualDeliveryTime?
+- contentAge (ms)
+- engagement: {TAPPED, DISMISSED, IGNORED}?
+- failureReason?
+- platformInfo (oem, os version, app state)
+```
+- Compute: **Fetch Success Rate**, **Delivery Rate**, **Engagement Rate**, **Stale Content Rate**.
+
+## 12) Testing Requirements
+### Matrix (minimum)
+- Android 12+ foreground/background/killed; with/without Battery Saver; Wi‑Fi/Mobile/Offline.
+- iOS 16+ background/Low Power/Focus/Scheduled Summary on & off.
+- Offline at trigger time (must still display).
+
+### Unit Tests (examples)
+- Fallback when fetch fails (uses last-good and marks stale).  
+- Exact vs inexact scheduling path selected correctly.  
+- Metrics recorded for each stage.
+
+## 13) UX Standards
+- One clear message; no clutter.  
+- ≤2 actions; primary takes user into app.  
+- Respect quiet hours if configured.  
+- Provide onboarding: value explanation → permission request → time picker → test notification → tips for OEM battery settings (Android) or Focus/Summary (iOS).
+
+## 14) Code Stubs (must generate & wire)
+### Android — Worker (core pattern)
+```kotlin
+class DailyContentWorker(ctx: Context, params: WorkerParameters) : CoroutineWorker(ctx, params) {
+    override suspend fun doWork(): Result = try {
+        withTimeout(8.minutes) {
+            val content = fetchDailyContent(timeout = 30.seconds)
+            saveToCache(content)
+            scheduleNotification(content)
+        }
+        Result.success()
+    } catch (e: TimeoutCancellationException) {
+        scheduleFromCache(); Result.success()
+    } catch (e: Exception) {
+        scheduleFromCache(); Result.retry()
+    }
+}
+```
+### iOS — BG Refresh Handler (core pattern)
+```swift
+func handleBackgroundRefresh(_ task: BGAppRefreshTask) {
+    scheduleNextRefresh()
+    var finished = false
+    task.expirationHandler = { if !finished { cancelNetwork(); task.setTaskCompleted(success: false) } }
+    fetchDailyContent(timeout: 15) { result in
+        defer { finished = true; task.setTaskCompleted(success: result.isSuccess) }
+        switch result {
+        case .success(let content): quickSave(content); scheduleNotification(content)
+        case .failure: scheduleFromCache()
+        }
+    }
+}
+```
+
+## 15) Security & Privacy
+- Use HTTPS; pin if required.  
+- Strip PII from payloads; keep content generic by default.  
+- Store only what is necessary; apply cache quotas; purge on logout/uninstall.  
+- Respect OS privacy settings (Focus, Scheduled Summary, Quiet Hours).
+
+## 16) Troubleshooting Playbook (LLM should generate helpers)
+- Android: verify permission, channel, OEM battery settings; `adb shell dumpsys notification`.  
+- iOS: check authorization, Background App Refresh, Low Power, Focus/Summary state.
+
+## 17) Roadmap Flags (implement behind switches)
+- `FEATURE_MEDIA_ATTACHMENTS` (default off).  
+- `FEATURE_PERSONALIZATION_ENGINE` (time/frequency, content types).  
+- `FEATURE_PUSH_REALTIME` (server-driven for urgent alerts).
+
+## 18) Definition of Done
+- Notifications deliver daily at user-selected time **without network**.  
+- Graceful fallback chain proven by tests.  
+- Metrics recorded locally; viewable log.  
+- Clear onboarding and self-diagnostic screen.  
+- Battery/OS constraints documented; user education available.
+
+## 19) Quick Start (LLM execution order)
+1. Scaffold modules (Android + iOS).  
+2. Implement models + storage + fallback content.  
+3. Implement schedulers (AlarmManager / UNCalendarNotificationTrigger).  
+4. Implement background fetchers (WorkManager / BGTaskScheduler).  
+5. Wire onboarding + test notification.  
+6. Add metrics logging.  
+7. Ship minimal, then iterate.
