-**Document Version:** 1.0  
+### [Planner] Research Notes - RECIPE-0002 (2026-02-16)
-**Generated by:** Initializer Agent  
+
-**Next Update:** Planner Agent
+**Task:** Complete PWA implementation (installability, push notifications, share target)
+
+#### PWA Documentation Research
+**Research Date:** 2026-02-16  
+**Sources:** MDN Web Docs, web.dev, W3C specifications
+
+**Progressive Web Apps (PWA) - Key Requirements:**
+1. **Web App Manifest** (`manifest.json`)
+   - Required members: `name` or `short_name`, `icons` (192x192 PNG minimum), `start_url`, `display`
+   - Share target support via `share_target` member (method, action, params)
+   - Icons should include 192x192 and 512x512 sizes for optimal display
+   - Browser compatibility: Chrome/Edge (full), Firefox/Safari (limited for share_target)
+
+2. **Service Worker**
+   - Must be registered to enable offline functionality
+   - Lifecycle: install → activate → fetch events
+   - Required for push notifications
+   - Must be served over HTTPS (or localhost)
+
+3. **HTTPS Requirement**
+   - Mandatory for service worker registration
+   - Required for push notifications and other secure contexts
+   - Local development: `http://localhost` is treated as secure
+
+4. **Installability Criteria** (from MDN/web.dev):
+   - Valid manifest with required members
+   - Service worker registered with fetch event handler
+   - Served over HTTPS
+   - At least one 192x192 PNG or SVG icon
+   - Display mode set (fullscreen, standalone, minimal-ui)
+
+**Push Notifications (Web Push API):**
+- Requires service worker to receive push events
+- VAPID authentication (application server keys) required for Chrome
+- Subscription process: permission → subscribe → store subscription → send push
+- Push service (browser vendor controlled) routes messages
+- Notification permissions: default, granted, denied
+- Best practice: request permission after user interaction
+
+**Web Share Target API:**
+- Registers PWA as share destination
+- Configuration via manifest `share_target` member
+- Supports GET or POST methods
+- `params` define query string mapping (title, text, url)
+- Files can be shared via POST with `multipart/form-data`
+- Currently Chrome/Edge only (experimental)
+- App must be installed to appear in share sheet
+
+#### Current Implementation Analysis
+**Research Date:** 2026-02-16  
+**Files Analyzed:** manifest.json, service-worker.ts, app.html, svelte.config.js, PWAInstallManager.ts, PushNotificationManager.ts
+
+**Manifest Analysis (`static/manifest.json`):**
+- ✅ Has all required PWA members (name, short_name, start_url, display, scope, theme_color, background_color)
+- ✅ Share target configured correctly (GET /share with title/text/url params)
+- ⚠️ Icons reference `/favicon.png` but file does NOT exist in static folder
+- ⚠️ Uses same icon path for both 192x192 and 512x512 sizes
+- ℹ️ Missing optional but recommended members: `description`, `screenshots`, `categories`
+
+**Service Worker Analysis (`src/service-worker.ts`):**
+- ✅ Native SvelteKit service worker (migrated from vite-pwa plugin)
+- ✅ Install event: caches all build assets and static files
+- ✅ Activate event: cleans up old caches
+- ✅ Fetch event: cache-first for assets, network-first with cache fallback for others
+- ✅ Push event handler: processes push messages, shows notifications with actions
+- ✅ Notification click handler: opens/focuses app, handles action buttons
+- ✅ Notification close handler: tracks dismissals
+- ✅ Background sync handler: supports retry operations
+- ✅ Message handler: supports service worker communication
+- ✅ Global error handlers present
+
+**Service Worker Registration (`svelte.config.js`):**
+- ✅ `serviceWorker.register: true` enabled
+- ✅ SvelteKit handles registration automatically
+
+**Manifest Link (`src/app.html`):**
+- ✅ `<link rel="manifest" href="/manifest.json">` present in head
+
+**Client-Side Managers:**
+- ✅ `PushNotificationManager.ts`: Full implementation with permission, subscribe, unsubscribe
+- ✅ `PWAInstallManager.ts`: beforeinstallprompt handling, install prompt triggering
+- ✅ Both are SSR-safe with browser guards
+
+**Share Target (`/share` route):**
+- ✅ Route exists at `src/routes/share/+page.svelte`
+- ✅ Parses query params (text, url) from share target
+- ✅ Extracts Instagram URLs from shared text
+- ✅ Auto-processes URLs on mount
+- ✅ Enqueues items and redirects to dashboard
+
+**Icons/Assets Issue:**
+- ⚠️ **CRITICAL**: `manifest.json` references `/favicon.png` but file doesn't exist
+- ✅ `src/lib/assets/favicon.svg` exists (used in layout)
+- ⚠️ No PNG icons in `static/` folder
+- ⚠️ Service worker references `/favicon.png` for notifications
+
+**Push Notifications Infrastructure:**
+- ✅ VAPID keys configured in `queueConfig.push` (uses env vars or defaults)
+- ✅ Server endpoint: `/api/notifications/vapid-key` (GET)
+- ✅ Server endpoint: `/api/notifications/subscribe` (POST/DELETE)
+- ✅ PushNotificationService stores subscriptions in-memory
+- ℹ️ Note: Subscriptions are not persisted (lost on restart)
+
+#### What Works Already:
+1. **PWA Structure**: Complete Native SvelteKit PWA implementation
+2. **Service Worker**: Fully functional with caching, push, notifications
+3. **Push Notifications**: Client and server infrastructure in place
+4. **Share Target**: Configured in manifest and `/share` route working
+5. **Install Prompts**: PWAInstallManager ready to trigger install
+6. **HTTPS**: App served at https://localhost:5173/
+
+#### What Needs Attention:
+1. **Icons**: Create PNG icons (192x192, 512x512) from existing SVG
+2. **Icon Verification**: Ensure icons are properly sized and optimized
+3. **Installability Testing**: Verify all criteria met via chrome://pwa-internals
+4. **Push Notification Testing**: Verify VAPID key generation and push flow
+5. **Share Target Testing**: Test share from external apps (Instagram)
+6. **Manifest Enhancement**: Add description, categories for better discoverability
+
+#### Dependencies & Constraints (from ARCHITECTURE.md, CODE_STYLE.md):
+- Using native SvelteKit PWA (no plugins needed)
+- Service worker: `$service-worker` module provides build, files, version
+- Environment: uses `$env/dynamic/private` for server configs
+- HTTPS required (already configured at https://localhost:5173/)
+- TypeScript strict mode enabled
+- All file paths must use SvelteKit path aliases (`$lib`, `$service-worker`)
+
+#### Code Style Requirements (from CODE_STYLE.md):
+- FilesNaming: manifest.json, service-worker.ts, lowercase for utilities
+- Type annotations required for public APIs
+- SSR-safe code: all browser API usage must be guarded with `browser` check
+- Error handling: try-catch with descriptive messages
+- Comments: JSDoc for public APIs, inline for complex logic
