If exact access is missing on API 31+, we will use a **windowed trigger (default ±10m)** and surface a settings deep-link. +- **We will deep-link users to the exact-alarm settings when we detect denials.** +- **Channel defaults**: ID `timesafari.daily`, name "TimeSafari Daily", importance=high (IDs never change) +- Receivers for reboot/time change **will be handled** by v2 (plugin); in v1, re‑arming **will occur** on app start/resume. +- **Mobile local notifications will route via action listeners (not the service worker)**. + +**Web** +- Requires registered Service Worker + permission; can deliver with browser closed. **Web will not offline-schedule**. +- Service worker click handlers apply to **web push only**; local notifications on mobile do **not** pass through the SW. +- SW examples use `/sw.js` as a placeholder; **wire this to your actual build output path** (e.g., `sw_scripts/notification-click.js` or your combined bundle). +- **Note**: Service workers are **intentionally disabled** in Electron (`src/main.electron.ts`) and web uses VitePWA plugin for minimal implementation. + +**Electron** +- We **will use** native OS notifications with **best-effort scheduling while the app is running**; true background scheduling will be addressed in v2 (native bridges). + +**Electron delivery strategy (v1 reality + v2 path)** +We **will deliver** desktop notifications while the Electron app is running. True **background scheduling when the app is closed** is **out of scope for v1** and **will be addressed** in v2 via native bridges. We **will adopt** one of the following options (in order of fit to our codebase): + +**In-app scheduler + auto-launch (recommended now):** Keep the orchestrator in the main process, **start on login** (tray app, hidden window), and use the **Electron `Notification` API** for delivery. This requires no new OS services and aligns with our PlatformServiceFactory/mixin patterns. + +**Policy (v1):** If the app is **not running**, Electron will **not** deliver scheduled locals. With **auto-launch enabled**, we **will achieve** near-mobile parity while respecting OS sleep/idle behavior. + +**UX notes:** On Windows we **will set** `appUserModelId` so toasts are attributed correctly; on macOS we **will request** notification permission on first use. + +**Prerequisites:** We **will require** Node 18+ (global `fetch`) or we **will polyfill** via `undici` for content fetching in the main process. + +--- + +## 8) Template Engine Contract + +**Supported tokens:** `{{headline}}`, `{{summary}}`, `{{date}}` (YYYY-MM-DD), `{{time}}` (HH:MM). +**Escaping:** HTML-escape all injected values. +**Limits:** Title ≤ 50 chars; Body ≤ 200 chars; truncate with ellipsis. +**Fallback:** Missing token → `"[Content]"`. +**Mutation:** We **will** render templates **before** scheduling; no mutation at delivery time on iOS locals. + +## 9) Integration with Existing TimeSafari Infrastructure + +**Database:** We **will integrate** with existing migration system in `src/db-sql/migration.ts` following the established `MIGRATIONS` array pattern +**Settings:** We **will extend** existing Settings type in `src/db/tables/settings.ts` following the established type extension pattern +**Platform Service:** We **will leverage** existing PlatformServiceMixin database utilities following the established mixin pattern +**Service Factory:** We **will follow** the existing `PlatformServiceFactory` singleton pattern for notification service creation +**Capacitor:** We **will integrate** with existing deep link system in `src/main.capacitor.ts` following the established initialization pattern +**Service Worker:** We **will extend** existing service worker infrastructure following the established `sw_scripts/` pattern (Note: Service workers are intentionally disabled in Electron and have minimal web implementation via VitePWA plugin) +**API:** We **will use** existing error handling from `src/services/api.ts` following the established `handleApiError` pattern +**Logging:** We **will use** existing logger from `src/utils/logger` following the established logging patterns +**Platform Detection:** We **will use** existing `process.env.VITE_PLATFORM` patterns (`web`, `capacitor`, `electron`) +**Vue Architecture:** We **will follow** Vue 3 + vue-facing-decorator patterns for component integration (Note: The existing `useNotifications` composable in `src/composables/useNotifications.ts` is currently stub functions with eslint-disable comments and needs implementation) +**State Management:** We **will integrate** with existing settings system via `PlatformServiceMixin.$saveSettings()` for notification preferences (Note: TimeSafari uses PlatformServiceMixin for all state management, not Pinia stores) +**Identity System:** We **will integrate** with existing `did:ethr:` (Ethereum-based DID) system for user context +**Testing:** We **will follow** Playwright E2E testing patterns established in TimeSafari +**Database Architecture:** We **will support** platform-specific database backends: +- **Web**: Absurd SQL (SQLite via IndexedDB) via `WebPlatformService` with worker pattern +- **Capacitor**: Native SQLite via `CapacitorPlatformService` +- **Electron**: Native SQLite via `ElectronPlatformService` (extends CapacitorPlatformService) + +--- + +## 10) Error Taxonomy & Telemetry + +**Error Codes:** `FETCH_TIMEOUT`, `ETAG_NOT_MODIFIED`, `SCHEDULE_DENIED`, `EXACT_ALARM_MISSING`, `STORAGE_BUSY`, `TEMPLATE_MISSING_TOKEN`, `PERMISSION_DENIED`. + +**Event Envelope:** `code, slotId, whenMs, attempt, networkState, tzOffset, appState, timestamp`. + +--- + +## 11) Permission UX & Channels/Categories + +- We **will request** notification permission **after** user intent (e.g., settings screen), not on first render. +- **Android:** We **will create** a stable channel ID (e.g., `timesafari.daily`) and **will set** importance appropriately. +- **iOS:** We **will register** categories for optional actions;

No delivery-time network for locals. -- **Timeout:** `fetchTimeoutMs = 12s`, single attempt inside lead. -- **Scheduling:** Use non-repeating one-shots; maintain a rolling window under -the pending cap (~64). -- **v2 note:** Background **silent push** or BGTaskScheduler-based prefetch will -be addressed in the plugin (not in v1). - -**Android (Capacitor app, v1)** - -- **When code may run:** Same as iOS; no JS wake when app is killed. -- **Network in v1:** Fetch during app activity only. -- **Exact alarms:** If `SCHEDULE_EXACT_ALARM` is unavailable, we will schedule -at **window start** with `androidWindowLenMs = 10m`; OS may delay within the -window.

If - disabled, record `SCHEDULE_DENIED` and **do not** queue notifications. - -6. **Android window behavior** - - In `scheduleWindow(...)`, store `{ windowLenMs: 600000 }` in `extra` for - telemetry; schedule at window **start** and rely on OS batching. - -7. **Electron fetch prerequisite** - - If orchestrator runs in main, ensure Node 18+ or add at app start: - - ```ts - // main only, if Node < 18 - import 'undici/register'; - ``` - - - Set Windows AppUserModelID once: - - ```ts - import { app } from 'electron'; - if (process.platform === 'win32') app.setAppUserModelId('com.timesafari.app'); - ``` - -8. **Truncation order** - - Truncate template **before** escaping;

We **will support** online‑first (API→DB→Schedule) with offline‑first fallback. The system **will enhance** TimeSafari's community-building mission by keeping users connected to gratitude, gifts, and collaborative projects through timely, relevant notifications. - -> **Implementation Details:** See `notification-system-implementation.md` for detailed code, database schemas, and integration specifics. -> **Canonical Ownership:** This document owns Goals, Tenets, Platform behaviors, Acceptance criteria, and Test cases. - ---- - -## 1) Versioning & Intent - -- **v1 (In‑App Orchestrator):** We **will implement** multi‑daily local notifications, online/offline flows, templating, SQLite persistence, and eventing **inside the app** using Capacitor Local Notifications. -- **v2 (Plugin):** We **will extract** adapters to a Capacitor/Native plugin to gain native schedulers (WorkManager/AlarmManager; BGTask+UNUserNotificationCenter), native HTTP, and native SQLite **with the same TypeScript API**. - -> We **will retain** the existing web push + Service Worker foundation; the system **will add** reliable local scheduling on mobile and a unified API across platforms. - ---- - -## 2) Design Tenets - -- **Reliability:** OS‑level delivery once scheduled; no reliance on JS being alive at fire time. -- **Freshness:** Prefer online‑first within a short prefetch window; degrade gracefully to cached content with TTL. -- **Extractable:** Clean interfaces (Scheduler, DataStore, Callbacks) so v2 **will swap** adapters without API changes. -- **Simplicity:** One‑shot notifications per slot; rolling window scheduling to respect platform caps. -- **Observability:** Persist deliveries and errors; surface minimal metrics; enable ACKs. -- **Privacy-First:** Follow TimeSafari's privacy-preserving architecture; user-controlled visibility and data sovereignty. -- **Community-Focused:** Enhance TimeSafari's mission of connecting people through gratitude, gifts, and collaborative projects. - ---- - -## 3) Architecture Overview - -``` -Application (Vue/TS) - ├─ NotificationOrchestrator (core state) - │ ├─ Scheduler (adapter) - │ ├─ DataStore (adapter) - │ └─ Callbacks (adapter) - └─ UI (settings, status) - -Adapters - ├─ V1: SchedulerCapacitor, DataStoreSqlite, CallbacksHttp - └─ V2: SchedulerNative, DataStoreNativeSqlite, CallbacksNativeHttp - -**Scheduler Adapter:** All notification arming must go through the Scheduler adapter to honor platform timing semantics (exact alarms vs. windowed fallback). - -Platform - ├─ iOS/Android: LocalNotifications (+ native bridges later) - ├─ Web: Service Worker + Push (kept) - └─ Electron: OS notifications (thin adapter) -``` - -**Execution modes (concise):** - -- **Online‑First:** wake near slot → fetch (ETag, timeout) → persist → schedule; on failure → Offline‑First. -- **Offline‑First:** read last good payload from SQLite; if beyond TTL → skip notification (no retry). - ---- - -## 4) Public API (Shared by v1 & v2) - -**Core Types & Interface:** See Implementation document for complete API definitions, type interfaces, and design decisions. - -> **Storage semantics:** `'shared'` = app DB; `'private'` = plugin-owned/native DB (v2). (No functional difference in v1.) -> **Slot Identity & Scheduling Policy** -> • **SlotId** uses canonical `HHmm` and remains stable across timezone changes. -> • **Lead window:** default `prefetchLeadMinutes = 20`; no retries once inside the lead. -> • **TTL policy:** When offline and content is beyond TTL, **we will skip** the notification (no "(cached)" suffix). -> • **Idempotency:** Duplicate "scheduled" deliveries are prevented by a unique index on `(slot_id, fire_at, status='scheduled')`. -> • **Time handling:** Slots will follow **local wall-clock** time across TZ/DST; `slotId=HHmm` stays constant and we will **recompute fire times** on offset change. - ---- - -## 5) Data Model & Retention (SQLite) - -**Tables:** `notif_contents`, `notif_deliveries`, `notif_config` (see Implementation document for complete schema) - -**Retention:** We **will keep** ~14 days of contents/deliveries (configurable) and **will prune** via a simple daily job that runs on app start/resume. We **will prune** daily but **will not** VACUUM by default on mobile; disk compaction is deferred. - -**Payload handling:** We **will template** `{title, body}` **before** scheduling; we **will not** mutate at delivery time. - ---- - -## 6) Scheduling Policy & Slot Math - -- **One‑shot per slot** per day (non‑repeating). -- **Rolling window:** today's remaining slots; seed tomorrow where platform limits allow. -- **TZ/DST safe:** We **will recompute** local wall‑times on app resume and whenever timezone/offset changes; then **reschedule**. -- **Android exactness:** If exact alarms are unavailable or denied, we **will use** `setWindow` semantics via the scheduler adapter. -- **iOS pending cap:** We **will keep** pending locals within typical caps (~64) by limiting the window and canceling/re‑arming as needed. -- **Electron rolling window:** On Electron we **will schedule** the **next occurrence per slot** by default; depth (today+tomorrow) **will be** enabled only when auto-launch is on, to avoid drift while the app is closed. - ---- - -## 7) Timing & Network Requirements - -**Summary:** The notification system uses lightweight, ETag-aware content fetching with single attempts inside lead windows. All timing constants and detailed network policies are defined in the Implementation document. - -**Key Policies:** - -- **Lead policy:** The lead window governs **online-first fetch attempts**, not arming. We **will arm** locals **whenever the app runs**, using the freshest available payload. -- **TTL policy:** If offline and content is beyond TTL, we will **skip** the notification (no "cached" suffix). -- **Idempotency:** Duplicate "scheduled" rows are prevented by a unique index on `(slot_id, fire_at, status='scheduled')`. -- **Wall-clock rule:** Slots will follow **local wall-clock** across TZ/DST; `slotId=HHmm` stays constant and we will **recompute fire times** on offset change. -- **Resume debounce:** On app resume/open we will **debounce** pipeline entry points by **30s** per app session to avoid burst fetches. -- **No scheduled background network in v1 (mobile):** Local notifications **will deliver offline once armed**, but **we will not** run timed network jobs when the app is terminated. **Network prefetch will occur only while the app is running** (launch/resume/inside lead). Server-driven push (Web SW) and OS background schedulers are a **v2** capability. - -**Platform-Specific Network Access:** - -- **iOS:** Foreground/recently backgrounded only; no JS wake when app is killed -- **Android:** Exact alarms vs. windowed triggers based on permissions -- **Web:** Service Worker for push notifications only -- **Electron:** App-running only; no background network access - -**Optional Background Prefetch (v1):** - -- **Background Runner (optional, v1):** We **will integrate** Capacitor's Background Runner to **opportunistically prefetch** content on iOS/Android when the OS grants background time. This **will not** provide clock-precise execution and **will not** run after user-terminate on iOS. It **will not** be treated as a scheduler. We **will continue** to *arm* local notifications via our rolling window regardless of Runner availability. When Runner fires near a slot (inside `prefetchLeadMinutes`), it **will** refresh content (ETag, 12s timeout) and, behind a flag, **may** cancel & re-arm that slot with the fresh template if within TTL. If no budget or failure, the previously armed local **will** still deliver. - -**Implementation Details:** See Implementation document for complete timing constants table, network request profiles, and platform-specific enforcement. - ---- - -## 8) Platform Essentials - -**iOS** - -- Local notifications **will** fire without background runtime once scheduled. NSE **will not** mutate locals; delivery-time enrichment requires remote push (future). -- **Category ID**: `TS_DAILY` with default `OPEN` action -- **Background budget** is short and OS‑managed; any prefetch work **will complete** promptly. -- **Mobile local notifications will route via action listeners (not the service worker)**. -- Background Runner **will** offer **opportunistic** network wake (no guarantees; short runtime; iOS will not run after force-quit). Locals **will** still deliver offline once armed. - -**Android** - -- Exact alarms on **API 31+** may require `SCHEDULE_EXACT_ALARM`. If exact access is missing on API 31+, we will use a **windowed trigger (default ±10m)** and surface a settings deep-link. -- **We will deep-link users to the exact-alarm settings when we detect denials.** -- **Channel defaults**: ID `timesafari.daily`, name "TimeSafari Daily", importance=high (IDs never change) -- Receivers for reboot/time change **will be handled** by v2 (plugin); in v1, re‑arming **will occur** on app start/resume. -- **Mobile local notifications will route via action listeners (not the service worker)**. -- Background Runner **will** offer **opportunistic** network wake (no guarantees; short runtime; iOS will not run after force-quit). Locals **will** still deliver offline once armed. - -**Web** - -- Requires registered Service Worker + permission; can deliver with browser closed. **Web will not offline-schedule**. -- Service Worker click handlers are for **web push only**; **mobile locals bypass the SW**. -- SW examples use `/sw.js` as a placeholder; **wire this to your actual build output path** (e.g., `sw_scripts/notification-click.js` or your combined bundle). -- **Note**: Service workers are **intentionally disabled** in Electron (`src/main.electron.ts`) and web uses VitePWA plugin for minimal implementation. - -**Electron** - -- We **will use** native OS notifications with **best-effort scheduling while the app is running**; true background scheduling will be addressed in v2 (native bridges). - -**Electron delivery strategy (v1 reality + v2 path)** -We **will deliver** desktop notifications while the Electron app is running. True **background scheduling when the app is closed** is **out of scope for v1** and **will be addressed** in v2 via native bridges. We **will adopt** one of the following options (in order of fit to our codebase): - -**In-app scheduler + auto-launch (recommended now):** Keep the orchestrator in the main process, **start on login** (tray app, hidden window), and use the **Electron `Notification` API** for delivery. This requires no new OS services and aligns with our PlatformServiceFactory/mixin patterns. - -**Policy (v1):** If the app is **not running**, Electron will **not** deliver scheduled locals. With **auto-launch enabled**, we **will achieve** near-mobile parity while respecting OS sleep/idle behavior. - -**UX notes:** On Windows we **will set** `appUserModelId` so toasts are attributed correctly; on macOS we **will request** notification permission on first use. - -**Prerequisites:** We **will require** Node 18+ (global `fetch`) or we **will polyfill** via `undici` for content fetching in the main process. - ---- - -## 9) Template Engine Contract - -**Supported tokens:** `{{headline}}`, `{{summary}}`, `{{date}}` (YYYY-MM-DD), `{{time}}` (HH:MM). -**Escaping:** HTML-escape all injected values. -**Limits:** Title ≤ 50 chars; Body ≤ 200 chars; truncate with ellipsis. -**Fallback:** Missing token → `"[Content]"`. -**Mutation:** We **will** render templates **before** scheduling; no mutation at delivery time on iOS locals. - ---- - -## 10) Integration with Existing TimeSafari Infrastructure - -**Database:** We **will integrate** with existing migration system in `src/db-sql/migration.ts` following the established `MIGRATIONS` array pattern -**Settings:** We **will extend** existing Settings type in `src/db/tables/settings.ts` following the established type extension pattern -**Platform Service:** We **will leverage** existing PlatformServiceMixin database utilities following the established mixin pattern -**Service Factory:** We **will follow** the existing `PlatformServiceFactory` singleton pattern for notification service creation -**Capacitor:** We **will integrate** with existing deep link system in `src/main.capacitor.ts` following the established initialization pattern -**Service Worker:** We **will extend** existing service worker infrastructure following the established `sw_scripts/` pattern (Note: Service workers are intentionally disabled in Electron and have minimal web implementation via VitePWA plugin) -**API:** We **will use** existing error handling from `src/services/api.ts` following the established `handleApiError` pattern -**Logging:** We **will use** existing logger from `src/utils/logger` following the established logging patterns -**Platform Detection:** We **will use** existing `process.env.VITE_PLATFORM` patterns (`web`, `capacitor`, `electron`) -**Vue Architecture:** We **will follow** Vue 3 + vue-facing-decorator patterns for component integration (Note: The existing `useNotifications` composable in `src/composables/useNotifications.ts` is currently stub functions with eslint-disable comments and needs implementation) -**State Management:** We **will integrate** with existing settings system via `PlatformServiceMixin.$saveSettings()` for notification preferences (Note: TimeSafari uses PlatformServiceMixin for all state management, not Pinia stores) -**Identity System:** We **will integrate** with existing `did:ethr:` (Ethereum-based DID) system for user context -**Testing:** We **will follow** Playwright E2E testing patterns established in TimeSafari -**Database Architecture:** We **will support** platform-specific database backends: - -- **Web**: Absurd SQL (SQLite via IndexedDB) via `WebPlatformService` with worker pattern -- **Capacitor**: Native SQLite via `CapacitorPlatformService` -- **Electron**: Native SQLite via `ElectronPlatformService` (extends CapacitorPlatformService) - ---- - -## 11) Error Taxonomy & Telemetry - -**Error Codes:** `FETCH_TIMEOUT`, `ETAG_NOT_MODIFIED`, `SCHEDULE_DENIED`, `EXACT_ALARM_MISSING`, `STORAGE_BUSY`, `TEMPLATE_MISSING_TOKEN`, `PERMISSION_DENIED`. - -**Event Envelope:** `code, slotId, whenMs, attempt, networkState, tzOffset, appState, timestamp`. - ---- - -## 12) Permission UX & Channels/Categories - -- We **will request** notification permission **after** user intent (e.g., settings screen), not on first render. -- **Android:** We **will create** a stable channel ID (e.g., `timesafari.daily`) and **will set** importance appropriately. -- **iOS:** We **will register** categories for optional actions; grouping may use `threadIdentifier` per slot/day. - ---- - -## 13) Eventing & Telemetry - -**Error Codes:** `FETCH_TIMEOUT`, `ETAG_NOT_MODIFIED`, `SCHEDULE_DENIED`, `EXACT_ALARM_MISSING`, `STORAGE_BUSY`, `TEMPLATE_MISSING_TOKEN`, `PERMISSION_DENIED`. - -**Event Envelope:** `code, slotId, whenMs, attempt, networkState, tzOffset, appState, timestamp`. - -**Implementation:** See Implementation document for complete error taxonomy, event logging envelope, ACK payload format, and telemetry events. - ---- - -## 14) Feature Flags & Config - -**Key Flags:** `scheduler`, `mode`, `prefetchLeadMinutes`, `ttlSeconds`, `iosCategoryIdentifier`, `androidChannelId`, `prefetchRunner`, `runnerRearm`. - -**Storage:** Feature flags **will reside** in `notif_config` table as key-value pairs, separate from user settings. - -**Implementation:** See Implementation document for complete feature flags table with defaults and descriptions. - ---- - -## 15) Acceptance (Definition of Done) → Test Cases - -### Explicit Test Checks - -- **App killed → locals fire**: Configure slots at 8:00, 12:00, 18:00; kill app; verify notifications fire at each slot on iOS/Android -- **ETag 304 path**: Server returns 304 → keep previous content; locals fire with cached payload -- **ETag 200 path**: Server returns 200 → update content and re-arm locals with fresh payload -- **Offline + beyond TTL**: When offline and content > 24h old → skip notification (no "(cached)" suffix) -- **iOS pending cap**: Respect ~64 pending limit; cancel/re-arm as needed within rolling window -- **Exact-alarm denied**: Android permission absent → windowed schedule (±10m) activates; UI shows fallback hint -- **Permissions disabled** → we will record `SCHEDULE_DENIED` and refrain from queuing locals. -- **Window fallback** → when exact alarm is absent on Android, verify target fires within **±10m** of slot time (document as an E2E expectation). -- **Timezone change**: On TZ/DST change → recompute wall-clock times; cancel & re-arm all slots -- **Lead window respect**: No retries attempted once inside 20min lead window -- **Idempotency**: Multiple `runFullPipelineNow()` calls don't create duplicate scheduled deliveries -- **Cooldown guard**: `deliverStoredNow()` has 60s cooldown to prevent double-firing - -### Electron-Specific Test Checks - -- **Electron running (tray or window) → notifications fire** at configured slots using Electron `Notification` -- **Electron not running →** no delivery (documented limitation for v1) -- **Start on Login enabled →** after reboot + login, orchestrator **will re-arm** slots and deliver -- **Template limits honored** (Title ≤ 50, Body ≤ 200) on Electron notifications -- **SW scope** not used for Electron (click handlers are **web only**) -- **Windows appUserModelId** set correctly for toast attribution -- **macOS notification permission** requested on first use - -### Timing-Verifiable Test Checks - -- **iOS/Android (app killed):** locals will fire at their slots; no network activity at delivery time. -- **iOS/Android (resume inside lead):** exactly **one** online-first attempt occurs; if fetch completes within **12s** → content updated; otherwise offline policy applies. -- **Android (no exact access):** observed delivery is within **±10 min** of slot time. -- **Web push:** SW push event fetch runs once with **12s** timeout; if it times out, the push still displays (from payload). -- **Electron (app running):** timer-based locals fire on time; on reboot with **Start on Login**, orchestrator re-arms on first run. -- **TTL behavior:** offline & stale → **skip** (no notification posted). -- **ETag path:** with `304`, last payload remains; no duplicate scheduling rows (unique index enforced). -- **Cooldown:** calling `deliverStoredNow` twice within **60s** for same slot doesn't produce two notifications. -- **Closed app, armed earlier** → locals fire at slot; title/body match last rendered content (proves "render at schedule time" + adapter API). -- **Closed app, timezone change before slot** → on next resume, app recomputes and re-arms; already armed notifications will still fire on original wall-time -- **Mobile closed-app, no background network:** Arm at T–hours; kill app; verify locals fire with last rendered text; confirm **no** network egress at delivery. -- **Web push as network scheduler:** Send push with empty payload → SW fetches within 12s timeout → shows correct text;
