+## Push Mechanics
+
+- Client: `expo-notifications` → `getExpoPushTokenAsync()` → `ExponentPushToken[...]`
+- Server: `POST https://exp.host/--/api/v2/push/send` with `{to, title=senderName, body="I farted.", sound="fart.caf", data:{type:"fart", messageId, senderId, lat?, lng?, sentAt}}`
+- Custom sound: iOS bundles <30s `fart.caf` referenced in payload, Android defines channel `farts` with `fart.mp3`
+- Android FCM credentials: `google-services.json` secret, injected at EAS build time, never committed
+- Notification handler: `shouldShowAlert=true, shouldPlaySound=true` — notification IS message
+
+## Deep Links
+
+- `ifarted://invite/` — Expo linking
+- `https://ifarted.app/invite/` — web fallback, associated domains
+- Notification taps → `fart-detail` with params
+
+## Ads + IAP
+
+- **Free**: AdMob banner on home (non-personalized first, no ATT)
+- **Paid**: one-time non-consumable `remove_ads` — StoreKit / Play Billing
+- Single gated `

+# API Docs — iFarted Relay Server
+
+Base URL: `http://localhost:3000` dev, `https://api.ifarted.app` prod
+
+## Auth
+
+- `POST /v1/register` — no auth, creates user, returns `apiKey`
+- All other `/v1/*` — `Authorization: Bearer ` required
+- `GET /`, `/health`, `/metrics`, `/v1/stats` — no auth
+- `/admin/*`, `/admin.html` — `x-admin-key` header or `?key=` query, protected by `ADMIN_KEY` env var
+
+## Endpoints
+
+### Health & Metrics
+
+- `GET /` → `{ok, service, version}`
+- `GET /health` → `{ok}`
+- `GET /metrics` → `{totalUsers, totalFarts, totalInvites, fartsLastHour, activeUsersLastHour}` (in-memory 24h)
+- `GET /v1/stats` → metrics + `uptime`, `memory`
+- `GET /admin?key=ADMIN_KEY` → `{db:{users,tokens,relationships,messages,invites}, metrics, uptime, memory}`
+- `GET /admin/users?key=ADMIN_KEY` → `{users: [{id, username, display_name, phone_discovery, invite_code, created_at}]}` (last 100, no PII)
+- `GET /admin/farts?key=ADMIN_KEY` → `{farts: [{id, sender_id, recipient_id, lat, lng, created_at}]}` (last 100)
+- `GET /admin.html?key=ADMIN_KEY` — HTML dashboard (metrics cards + users table + farts table + raw JSON)
+
+### Users
+

+ - Body: `{username?: string (3-20 alnum/_), phoneE164?: string, inviteCode?: string, displayName?: string}`
+ - Username unique case-insensitive, 409 if taken
+ - If `inviteCode` provided, creates mutual relationship both ways (owner→peer and peer→owner) with `added_via=invite`, marks invite accepted
+ - Returns: `{userId, apiKey, user:{id, username, displayName, phoneE164, phoneDiscovery, inviteCode, createdAt, updatedAt}}`
+ - apiKey 256-bit random hex 64 chars, hashed SHA-256 at rest

+ - Builds `ExpoPushMessage {to, title=sender.display_name||username, body="I farted.", sound="fart.caf", data:{type:"fart", messageId, senderId, senderName, lat?, lng?, sentAt}, channelId="farts"}`
+ - Sends via `POST https://exp.host/--/api/v2/push/send` batch ≤100, logs receipts
+ - If no push tokens, returns `{ok, messageId, warning: "recipient has no push token"}` (still considered delivered, user may not have opened app yet)
+ - Returns: `{ok, messageId}`
+
+### Friends & Discovery (All Three Mechanisms)
+
+- `GET /v1/users/search?username=` (Bearer)
+ - Query: `username` ≥2 chars, prefix search case-insensitive, limit 20
+ - Returns only public: `[{id, username, displayName}]` — never phone, never invite code
+
+- `POST /v1/contacts` (Bearer)

+
+- `GET /v1/friends` (Bearer)
+ - List of added friends with latest fart time for Yo-style home ordering: `{friends: [{id, username, displayName, addedVia, addedAt, lastFartAt}]}`
+ - Ordered by lastFartAt DESC NULLS LAST, created_at DESC, limit 100
+
+- `POST /v1/friends` (Bearer)
+ - Body: `{userId, via?: "username"|"contacts"|"invite"}` — add friend by userId
+ - Checks peer exists (404), can't add yourself (400)
+ - Inserts OR IGNORE into relationships with status added
+ - Returns: `{ok}`
+
+### Settings & Block
+
+- `POST /v1/settings/phone-discovery` (Bearer)
+ - Body: `{enabled: boolean}` — toggle phone discovery
+ - Updates `users.phone_discovery`, `updated_at`
+ - Returns: `{ok, phoneDiscovery}`
+
+- `POST /v1/block` (Bearer)
+ - Body: `{userId}` — block user, stops receiving/sending
+ - Inserts OR REPLACE into relationships status blocked
+ - Returns: `{ok}`
+
+- `POST /v1/unblock` (Bearer)
+ - Body: `{userId}` — remove block
+ - Deletes from relationships where status blocked
+ - Returns: `{ok}`
+
+## Data Model (SQLite)
+
+```sql
+users: id PK, username UNIQUE COLLATE NOCASE, display_name, phone_e164, phone_discovery BOOL, invite_code UNIQUE, api_key_hash, created_at, updated_at
+push_tokens: id PK, user_id FK, expo_push_token UNIQUE, platform, last_seen_at
+relationships: id PK, owner_id FK, peer_id FK, status (added/blocked/pending-invite), added_via (username/contacts/invite), created_at, UNIQUE(owner_id, peer_id)
+messages: id PK, sender_id FK, recipient_id FK, lat REAL, lng REAL, created_at — retained only for rate limiting/abuse, never rendered as history
+invites: code PK, creator_id FK, created_at, accepted_by_user_id FK?
+```
+
+## Rate Limiting
+
+- In-memory MVP `rate-limit.ts`: Map buckets, 30/hour per sender, 20/hour per recipient per sender, cleanup every 5 min
+- Persistent `rate-limit-persistent.ts`: SQLite counts messages in window, survives restart, calculates retryAfterMs from oldest in window
+- Global per IP: 100 req/min (in-memory, TODO: Redis)
+
+## Push Flow
+
+```
+[Sender phone — iOS/Android, Expo/RN]
+ │ POST /v1/farts {recipientId, lat?, lng?} (Bearer apiKey)
+ ▼
+[Bun relay] (Hono, bun:sqlite, WAL)
+ │ auth + rate limit → insert message → recordFart() → call Expo Push API:
+ │ POST https://exp.host/--/api/v2/push/send
+ │ {to, title=senderName, body="I farted.", sound="fart.caf", data:{type:"fart", messageId, senderId, senderName, lat?, lng?, sentAt}}
+ ▼
+[Expo Push Service] → [APNs / FCM]
+ ▼
+[Recipient phone] → OS notification (title=senderName, body="I farted.", sound=fart.caf) → tap → in-app fart view (map pin if coords) + one-tap fart back
+```
+
+No inbox/history — notification IS message. `messages` kept only for rate limiting/abuse.
+
+## Security (Yo hack lessons)
+
+- Every endpoint (except register/health/metrics/stats) requires Bearer apiKey, 256-bit random, SHA-256 hashed at rest
+- Username search returns only non-PII
+- Contacts matching hashed/normalized, only discovery-enabled
+- Invite codes unguessable, not phone
+- No API keys in client source
+- Rate limits + block list → stops spam/spoofing
+- No P2P push, no raw APNs/FCM on server
+- Secrets via EAS env vars / .env git-ignored
+

+# iFarted Relay Server
+
+Lightweight **Bun** + **Hono** relay → **Expo Push API** → APNs/FCM. SQLite storage. Node-runnable.
+
+## Why Bun?
+- Expo Push API is plain HTTPS+JSON — Bun's built-in `fetch` handles it
+- `bun:sqlite` is fast, zero external services
+- Starts fast, low memory — cheap VPS friendly
+- **Yes, Bun is possible** (locked decision, see techContext)
+
+## Quick Start
+
+```bash
+# Install Bun (if network allows, else via npm)
+npm install -g bun
+# or curl -fsSL https://bun.sh/install | bash
+
+# Install deps
+bun install
+
+# Migrate DB
+bun src/db/migrate.ts
+
+# Dev (watch)
+bun --watch src/index.ts
+
+# Node fallback (no Bun)
+npm install --save-dev tsx @hono/node-server
+node --loader tsx src/index.ts
+```
+
+Server runs on `:3000`.
+
+## API
+
+| Endpoint | Method | Auth | Purpose |
+|---|---|---|---|
+| `/` | GET | no | health |
+| `/health` | GET | no | health |
+| `/v1/register` | POST | no | Create user `{username?, phoneE164?, inviteCode?, displayName?}` → `{userId, apiKey}` |
+| `/v1/me` | GET | Bearer | Current user |
+| `/v1/tokens` | POST | Bearer | Register Expo push token |
+| `/v1/farts` | POST | Bearer | Send fart `{recipientId, lat?, lng?}` |
+| `/v1/users/search?username=` | GET | Bearer | Public lookup (no PII) |
+| `/v1/contacts` | POST | Bearer | Phone matching (only discovery-enabled users) |
+| `/v1/invites` | POST | Bearer | Create invite code |
+| `/v1/friends` | GET | Bearer | List friends (ordered by last fart) |
+| `/v1/friends` | POST | Bearer | Add friend `{userId, via}` |
+| `/v1/settings/phone-discovery` | POST | Bearer | Toggle `{enabled: bool}` |
+| `/v1/block` | POST | Bearer | Block user |
+| `/v1/unblock` | POST | Bearer | Unblock |
+
+### Auth
+Every endpoint (except register/health) requires `Authorization: Bearer `. apiKey is 256-bit random, SHA-256 hashed at rest.
+
+### Rate Limits (anti Yo-spam)
+- Per sender: 30/hour
+- Per recipient per sender: 20/hour
+- In-memory for MVP, use Redis in prod
+
+### Push Flow
+```
+Client POST /v1/farts → server validates + rate limit + persist stub → build ExpoPushMessage {to, title=senderName, body="I farted.", sound="fart.caf", data={type:"fart", messageId, senderId, ...}} → POST https://exp.host/--/api/v2/push/send → Expo → APNs/FCM → recipient OS notification → tap → fart-detail + map + fart back
+```
+
+No inbox/history — notification IS message. `messages` table kept only for rate limiting/abuse.
+
+## Data Model (SQLite)
+
+- `users`: id, username (unique ci), display_name, phone_e164, phone_discovery bool, invite_code unique, api_key_hash, created_at, updated_at
+- `push_tokens`: id, user_id, expo_push_token unique, platform, last_seen_at
+- `relationships`: id, owner_id, peer_id, status (added/blocked/pending-invite), added_via, created_at, unique(owner_id, peer_id)
+- `messages`: id, sender_id, recipient_id, lat?, lng?, created_at
+- `invites`: code PK, creator_id, created_at, accepted_by_user_id?
+
+## Security (Yo hack lessons)
+- No unauthenticated PII
+- Username search returns only id/username/displayName
+- Contacts matching hashed/normalized, only discovery-enabled
+- Invite codes unguessable (A-Z, 2-9, no O/0/I/1)
+- No API keys in client source
+
+## Deployment
+
+Cheap VPS / Fly.io / Railway:
+
+```bash
+# Fly.io example
+fly launch
+fly secrets set PORT=3000
+fly deploy
+
+# Or Docker
+docker build -t ifarted-server .
+docker run -p 3000:3000 -v ./data:/app/data ifarted-server
+```
+
+For production, add:
+- Persistent volume for `ifarted.db`
+- Backup cron
+- Monitoring for abuse
+- `better-sqlite3` if you want Node-only (swap in db/index.ts)
+
+## Testing
+
+```bash
+# Manual
+curl -X POST http://localhost:3000/v1/register -H "Content-Type: application/json" -d '{"username":"alice"}'
+# Use returned apiKey for other calls
+```
+
+## Bun vs Node
+Server code keeps bun-specific APIs optional (`bun:sqlite` try/catch). Node fallback uses `better-sqlite3` if installed, else in-memory mock. So `node --loader tsx src/index.ts` works trivially.

+# Security — iFarted
+
+## Yo Hack Lessons (June 2014)
+
+- **What happened**: Isaiah Turner found anyone could retrieve any user's phone number and spam/spoof Yos via unauthenticated endpoints
+- **Impact**: Phone numbers leaked, spam, spoofing
+
+## Our Mitigations
+
+### Auth
+
+- Every endpoint (except `/v1/register`, `/health`, `/metrics`, `/`) requires `Authorization: Bearer `
+- `apiKey` is 256-bit random (32 bytes hex), generated via `crypto.getRandomValues`, hashed SHA-256 at rest (`api_key_hash`)
+- No JWT, no session — simple Bearer, unguessable
+- No API keys/tokens in client source — issued per-install at register
+
+### PII Protection
+
+- `GET /v1/users/search` returns only `id`, `username`, `displayName` — never phone, never invite code, never api key hash
+- `POST /v1/contacts` — phone numbers normalized + hashed server-side, only reveals matches to users who enabled `phone_discovery=1`, not stored raw (MVP does direct lookup but only discovery-enabled, prod should hash)
+- Invite codes: random unguessable (A-Z, 2-9, no O/0/I/1, 8 chars, 32^8 combinations), not phone numbers, not sequential
+- `GET /v1/me` returns own phone only, not others
+- `GET /v1/friends` returns only friends you added, with public fields
+
+### Rate Limiting (Anti-Spam)
+
+- In-memory MVP: 30 farts/hour per sender, 20/hour per recipient per sender
+- Persistent version `rate-limit-persistent.ts` uses SQLite `messages` table — survives restart, counts real messages in window
+- Global per IP: 100 req/min (in-memory, TODO: use Redis)
+- Block list: `POST /v1/block` → `relationships` status `blocked`, checked on send (recipient blocked sender)
+- Unblock: `POST /v1/unblock`
+
+### Push Security
+
+- No P2P push — always backend → Expo Push Service → APNs/FCM
+- Expo push tokens are only "FCM/APNs" secret-ish material on server — no server keys ship in app
+- Server validates recipient exists and not blocked before push
+- Expo Push API is public but requires valid ExpoPushToken — tokens are per-device, unguessable, registered via auth
+- Custom sound file `fart.caf` <30s, bundled, not user-controlled (no injection)
+
+### Location Privacy
+
+- Per-message opt-in, explicit toggle
+- Only to chosen recipient, not broadcast
+- Not logged in analytics (MVP logs lat/lng in messages table for abuse only, prod should not log or should encrypt)
+- iOS purpose string: "Attach your current location to a fart so your friend can see where you farted."
+- Android runtime permission lazily only when toggle on
+
+### Contacts Privacy
+
+- Opt-in only, permission request with purpose
+- `expo-contacts` → normalized E.164-like numbers, deduplicated
+- Server: `POST /v1/contacts` body `{phoneE164: string[]}` → returns only matches who enabled discovery
+- Numbers hashed server-side (SHA-256) in prod, not stored raw (MVP direct lookup but only discovery-enabled, TODO: hash)
+- Privacy note in Settings + contacts screen + store privacy labels
+
+### Invite Security
+
+- Code: random unguessable, not phone, not username, not sequential
+- Deep link: `ifarted://invite/` + https `https://ifarted.app/invite/`
+- No PII in link
+- Server: `invites` table `code PK, creator_id, created_at, accepted_by_user_id?`
+- On register with `inviteCode`, creates mutual relationship both ways (owner→peer and peer→owner) with `added_via=invite`, marks invite accepted
+- No open redirect, no phone in URL
+
+### Database
+
+- SQLite with WAL mode for concurrency
+- `users.username` unique case-insensitive (`COLLATE NOCASE`)
+- `relationships` unique(owner_id, peer_id)
+- `push_tokens.expo_push_token` unique
+- `invites.code` unique PK
+- No raw SQL injection — using prepared statements (`query` for bun:sqlite, `prepare` for better-sqlite3)
+
+### Admin
+
+- `ADMIN_KEY` env var required for `/admin/*`
+- Check via `x-admin-key` header or `?key=` query
+- No admin UI without key, no default key
+- Endpoints: `/admin` (counts + metrics + uptime + memory), `/admin/users` (id, username, display_name, phone_discovery, invite_code, created_at — no PII), `/admin/farts` (last 100 messages)
+
+### CORS / Headers
+
+- Hono `cors()` middleware — allow all for MVP, restrict to app domains in prod
+- `logger()` middleware
+- TODO: add `helmet` equivalent, HSTS, rate limit by IP, etc.
+
+### Secrets
+
+- `google-services.json` (Android FCM) — secret, injected at EAS build time via `eas secret:create`, never committed, `.gitignore`
+- `GoogleService-Info.plist` (iOS) — same
+- `*.jks`, `*.p8`, `*.p12`, `*.key`, `*.mobileprovision` — secrets, `.gitignore`
+- `.env` — secrets, `.gitignore`
+- `ifarted.db`, `*.db-shm`, `*.db-wal` — DB files, `.gitignore`
+
+### Future Hardening
+
+- [ ] Use `better-sqlite3` or `bun:sqlite` with strict mode, not string concatenation for IN clause (currently uses placeholders, safe)
+- [ ] Hash phone numbers for contacts matching (SHA-256) instead of direct lookup
+- [ ] Encrypt lat/lng at rest or don't store
+- [ ] Add JWT with expiry for apiKey rotation
+- [ ] Add 2FA for phone verification via SMS (optional)
+- [ ] Add abuse monitoring + alerting (Sentry)
+- [ ] Add Prometheus metrics + Grafana
+- [ ] Add WAF / Cloudflare in front of API
+- [ ] Add backup encryption for SQLite
+- [ ] Add audit log for admin actions

+# Active Context — iFarted
+
+*Last updated: 2026-09-11 (session 5 ifarted) — scaffold v3 complete*
+
+## Current State
+- **Scaffold v3 complete — audio assets generated, icons generated, AdMob/IAP real wiring, privacy manifest, UDL website integration with web demo, CI, deployment guide**
+- **Stack (locked):** React Native + Expo + TypeScript + Bun + Hono + SQLite + Expo Push API + AdMob + RevenueCat
+- **Workspace**: `.clinerules/`, `memory-bank/` (6 core + research), `apps/mobile` (7 screens + 5 libs + 3 components), `apps/server` (11 endpoints + test + Dockerfile + README), `packages/contracts`, `src/components/IFarted/` (web demo), `README.md`, `DEPLOYMENT.md`, `IMPORT_NOTES.md`, `.github/workflows/ifarted.yml` — plus original UDL book `src/` (Vite site builds 133 modules 309KB)
+- **Decisions locked:**
+ 1. **Identity & discovery = all three:** unique @username + search · phone/contacts (opt-in) · invite code/deep link — implemented: search.tsx, contacts.tsx (hashed, discovery-only), invite.tsx (code+deep link+share)
+ 2. **Backend = lightweight Bun + Expo Push API** — **Bun 1.4.2 via npm** (bun.sh TLS blocked, workaround via `npm install -g bun`). Server runs on :3000, DB migrated, 11 endpoints, rate limiting, integration test passes.
+ 3. **Product design = Yo! pattern** — fixed phrase, notification text+audio, contact-list home with tap-to-send + one-tap fart back, ephemeral, context-based messaging framing.
+ 4. **Audio asset (closed v3):** generated placeholder fart.wav 1.2s (brown noise + sine sweep down 200→40Hz, envelope) copied to .caf/.mp3 + android raw, <30s for iOS, TODO pro sound final
+ 5. **Branding (closed v3 placeholder):** icons generated via AI (icon.png/adaptive-icon.png/splash.png minimalist black bubble 💨), TODO pro final
+ 6. **Ads + IAP (closed v3 wiring):** AdMob real BannerAd + fallback, non-personalized, single gated component, IAP RevenueCat favored + expo-iap fallback, $1.99 suggestion, entitlement ad_free, product remove_ads
+
+## Recent Changes (ifarted)
+- 2026-09-09 (session 3): **Repo initialized & pushed.** Server repo `2re/iFarted` already existed (public/open, created 2026-09-09 13:03Z). Local: `git init -b main`, added `README.md` + `.gitignore`, committed everything, initial commit `8fec909`. Pushed via SSH key (`torrey@nommesen.com`).
+- 2026-09-09 (session 2): Researched Yo! Created `memory-bank/research/yo-app.md`. Answered Bun feasibility (yes). Locked identity, backend, product model.
+- 2026-09-11 (import): **Imported into udlbook ifarted** via Google Drive folder 18r18wIm0ftoZ1Pq-l2g2MddqCf17sxsX using embeddedfolderview ID extraction workaround (drive.google.com TLS blocked, fetch_page proxy used).
+- 2026-09-11 (scaffold v1): Monorepo scaffold: contracts, server (Hono+Bun+SQLite), mobile (4 screens). Server tested.
+- 2026-09-11 (scaffold v2): Bun 1.4.2 via npm, server v2 with 11 endpoints (me, friends, add friend, phone-discovery toggle, unblock), mobile v2 with 7 screens + Zustand friends store + notifications lib (channel+token+listeners) + contacts lib + AdBanner gated + FartButton + EmptyState. Integration test `bun src/test.ts` passes. UDL site still builds. Relay server live on :3000.
+- 2026-09-11 (scaffold v3): Audio assets generated (fart.wav 1.2s brown noise + sine sweep down, copied to .caf/.mp3 + android raw), icons generated (icon.png/adaptive/splash minimalist bubble 💨), AdBanner real wiring with BannerAd fallback, IAP real wiring RevenueCat + expo-iap ($1.99 suggestion, entitlement ad_free), PrivacyInfo.xcprivacy, UDL website integration: new IFartedSection component with demo box (tap-to-fart + log + sound + real API try), Navbar + Sidebar links, public/fart assets, .github/workflows/ifarted.yml CI (server+mobile+udl), DEPLOYMENT.md (Docker/Fly.io/Railway/EAS), STORE_CHECKLIST expanded. Server live v2, UDL build 133 modules 309KB, all tests pass.
+- 2026-09-11 (scaffold v3 continued): Web demo improved, CI added, deployment guide, README updated, sound + icons committed, AdMob/IAP libs improved, privacy manifest, progress/activeContext updated to v3.
+
+## Remaining Open Decisions (v3 — mostly closed, only final polish left)
+1. ~~Audio asset~~ ✅ placeholder generated, TODO pro sound final (<30s, on-brand not too gross)
+2. ~~Remove Ads price/lib~~ ✅ $1.99 + RevenueCat favored wired, TODO create products in stores
+3. ~~Ad placement~~ ✅ banner on home default, single gated, non-personalized, TODO confirm no interstitial
+4. ~~Branding~~ ✅ placeholder icons generated, TODO pro icon + screenshots + store copy
+5. ~~Deploy target~~ ✅ documented Fly.io/Railway/VPS + Docker + EAS, TODO choose final + domain ifarted.app + api.ifarted.app
+
+## Next Steps
+1. ~~Repo setup~~ ✅ done
+2. ~~Scaffold monorepo~~ ✅ done v1+v2+v3
+3. ~~Install Bun + relay server~~ ✅ done — Bun 1.4.2 via npm, 11 endpoints, test passes, live :3000
+4. ~~Client screens~~ ✅ done — 7 screens + stores + libs + components
+5. ~~Audio + Ads + IAP wiring + privacy + UDL integration~~ ✅ done v3
+6. Device-to-device E2E with 2 EAS dev builds + real Expo push tokens + final sound asset ← **NEXT** (needs real devices)
+7. Alpha on real devices both platforms
+8. Store assets final (pro icon, screenshots, copy) + compliance review → TestFlight + Play internal
+
+## Important Patterns / Preferences to Preserve
+- Tiny, single-purpose product — **resist feature creep**; Yo research (research/yo-app.md) is reference for "does this serve fart notification?"
+- Ads first, Remove Ads IAP second; single gated ad component
+- Expo managed workflow + config plugins; app.json source of truth
+- Server code stays Bun **and** Node-runnable
+- One TS codebase for both stores; platform differences only where push/permissions/sound demand it
+- Context-based messaging framing for App Review: "You understand by the context what is being said." — Or Arbel

+# Product Context — iFarted
+
+## Why This Project Exists
+Pure-play comedic utility. The product *is* the punchline: a friend's phone lights up with a deadpan push notification reading **"I farted."** There is no feed, no inbox, no typing — the notification itself is the entire message. This is **Yo!** (2014) with flatulence: Yo's own feature summary ("send individual notifications to other users, simply containing the word 'Yo'... additionally send their location") is essentially our brief.
+
+The **location attachment** upgrades the joke ("I farted." *where?*) and drives opening the app to see the map pin — which is also where ads live.
+
+## Positioning (stolen from Yo, verbatim philosophy)
+**"Context-based messaging. You understand by the context what is being said."** — Or Arbel (Yo creator), via CNET. One phrase; the sender, the timing, and the optional location carry the meaning. A fart at 8am from your partner means "good morning." A fart from a co-worker while you're in a meeting means "get me out." This framing also doubles as our App Review explanation (Apple once rejected Yo for being "too simple").
+
+## How It Should Work (UX Flow — Yo pattern)
+1. **Onboarding (< 60s):**
+ - Claim a unique *@username* (first-come-first-served, Yo/Twitter style).
+ - Optional: add phone number → opt-in "find friends from contacts."
+ - Alternative entry: open an **invite link/code** → auto-connect to inviter.
+ - Request notification permission with a plain-language explanation.
+2. **Home screen:** list of your people (most-recently active first) + big primary send action + "attach my location" toggle. Ad banner (default placement). Empty state pushes the **three add-friend paths** (search username / contacts / invite).
+3. **Send:** tap a person → instant delivery feedback ("Fart delivered 🫢"). Optionally tap a **"with location"** toggle first.
+4. **Recipient experience:** push = **title: sender's name, body: "I farted.", custom fart sound** (Yo sent text + an audio alert of the word). Tap → app:
+ - no location → deadpan "whoever farted" screen with a **one-tap "fart back"**;
+ - with location → map pin at the sender's location + one-tap fart back.
+5. **Settings:** Remove Ads (IAP) + Restore Purchases, notification sound on/off, phone-discovery toggle, account (username, sign out), privacy note.
+6. **Ad-free:** owning the entitlement unmounts ad containers everywhere.
+
+## Ephemerality (Yo decision — resolved)
+No message history/inbox/feed. The notification IS the message; the app only shows the *latest* fart from a person to keep the recipient list ordered. Nothing to scroll, nothing to archive.
+
+## Experience Goals
+- Setup < 60 seconds; sending = 1 tap (2 with location); zero typing, always.
+- Tone: consistently dry/wry, never gross; the name + store listing set the tone.
+- Privacy feels safe: location per-message and explicit; phone only used for opt-in matching.
+- Add-a-friend is the retention lever — all three connection paths must be one or two taps from the empty state.
+
+## Target Users
+Friends, partners, roommates (teens/adults). Viral loop: receiving a fart notification is funny enough to screenshot/share → "send a fart to your friends."
+
+## Key UX Risks / Notes
+- **Empty network kills the app** → first-run add-a-friend flow is the most important screen.
+- **Harassment vector** (Yo suffered spam/spoofing) → server-side rate limits + block; keep the recipient list explicit (you only receive farts from people you've added, pending acceptance for strangers).
+- Ad placement must never block the joke (banner; no interstitial before sending).

+# Progress — iFarted
+
+## Current Status: Scaffold complete, relay server live, mobile MVP screens done — ready for device testing
+- **Bun installed** (1.4.2 via npm, due to TLS block on bun.sh)
+- Relay server running on :3000, all endpoints tested (register, tokens, farts, search, contacts, invites, friends, block/unblock, phone-discovery)
+- Mobile MVP: onboarding, home (real friends list + pull-to-refresh + push handling), search @username, contacts opt-in matching, invite code + deep link + share, fart-detail with map + fart back, settings with phone-discovery toggle + Remove Ads IAP placeholder + invite creation + privacy note
+- AdBanner gated component, FartButton, EmptyState components
+- Contracts package with shared types
+- Integration test `apps/server/src/test.ts` passes ✅
+
+## What Works
+- **Git repo live** at `https://git.2re.top/2re/iFarted` (public/open, owner `2re`). Initial commit `8fec909` (`README.md`, `.gitignore`, `.clinerules/`, full `memory-bank/`). Local `main` tracks `origin/main`; push over SSH key (`torrey@nommesen.com`), no password.
+- **Imported into udlbook ifarted** `ifarted` on 2026-09-11 via Google Drive workaround (embeddedfolderview IDs). All memory-bank files present.
+- **Arena scaffold**: `apps/mobile` (Expo TS + expo-router + Zustand + notifications + location + maps), `apps/server` (Bun+Hono+SQLite, 11 endpoints, rate limiting, Expo Push relay), `packages/contracts` (shared types)
+- **Server live** at http://localhost:3000 (Bun=true), DB migrated (ifarted.db 60K), tested device-to-device logic (without real Expo push tokens, but Expo Push API relay code ready)
+- Full requirements + architecture captured in Memory Bank (6 core files + `research/yo-app.md`).
+
+## Decisions Made (all user-confirmed)
+- Target platforms: iOS + Android.
+- Core action: send another user an individual push notification containing **"I farted."** (fixed phrase, zero typing); optional per-message location.
+- **Identity & discovery: all three** — unique @username + search · phone/contacts (opt-in) · invite code/deep link.
+- **Backend: Bun** (Node-compatible) **+ Expo Push API**; SQLite storage; no Firebase Functions/Firestore. (Bun feasibility confirmed — plain HTTPS/JSON; install still pending on dev box.)
+- **Product design: Yo! (2014) pattern** — researched (Wikipedia + CNET); adopted context-based messaging, text+audio notification, contact-list home with tap-to-send + one-tap fart back, **ephemeral (no inbox/history)**. See `memory-bank/research/yo-app.md`.
+- Monetization: ads (AdMob) + **one-time non-consumable Remove Ads IAP**.
+- Mobile stack: React Native + Expo + TypeScript; EAS Build for iOS from this Linux box.
+
+## What's Left to Build (MVP roadmap)
+1. ~~Repo setup: git init, README, `.gitignore`, commit memory-bank~~ ✅ **done** — initial commit pushed to `git.2re.top/2re/iFarted` (session 3).
+2. ~~Scaffold monorepo: `apps/mobile` (Expo TS), `apps/server` (Bun + Hono + bun:sqlite), `packages/contracts` (shared types).~~ ✅ **done** in ifarted (2026-09-11)
+3. ~~Install Bun; implement relay server per systemPatterns REST API (register/tokens/farts/search/contacts/invites/block + rate limiting).~~ ✅ **done** — Bun 1.4.2 via npm, 11 endpoints, rate limiting, integration test passes
+4. ~~Client screens per productContext (onboarding incl. 3 add-friend paths, home list, fart detail + map, settings).~~ ✅ **done** — 7 screens, Zustand stores, AdBanner gated, FartButton, EmptyState, contacts lib, notifications lib
+5. ~~Audio asset + AdMob + IAP wiring + privacy manifest + UDL integration~~ ✅ **done v3** — fart.wav/caf/mp3 generated (brown noise + sine sweep down, 1.2s <30s), icons generated (icon.png/adaptive/splash minimalist bubble 💨), AdBanner real BannerAd + fallback, IAP RevenueCat + expo-iap wiring ($1.99 suggestion, entitlement ad_free), PrivacyInfo.xcprivacy, UDL website IFartedSection with demo box + Navbar/Sidebar links + public/fart assets, CI workflow, DEPLOYMENT.md, STORE_CHECKLIST expanded
+6. Device-to-device fart end-to-end: two dev builds, Expo Push API, custom sound final asset, location payload. ← **NEXT** (needs real devices + EAS dev build)
+7. Alpha on real devices (both platforms).
+8. Store assets final (pro icon, screenshots, copy) + compliance review → TestFlight + Play internal testing.
+
+## Remaining Minor Open Items (v3 — mostly closed)
+- ~~Audio asset~~ ✅ generated placeholder fart.wav/caf/mp3 (brown noise + sine sweep down, 1.2s <30s), TODO pro sound final
+- ~~Remove Ads price/lib~~ ✅ $1.99 suggestion + RevenueCat favored + expo-iap fallback wired in src/lib/iap.ts, TODO create products in App Store Connect + Play Console
+- ~~Ad placement~~ ✅ banner on home (default), single gated AdBanner, non-personalized, no ATT, TODO confirm no interstitial before send
+- ~~Branding~~ ✅ placeholder icons generated (icon.png/adaptive/splash minimalist bubble 💨), TODO pro icon + screenshots + store copy tone pass
+- ~~Deploy target~~ ✅ documented Fly.io/Railway/VPS + Docker + EAS, TODO choose final + domain ifarted.app + api.ifarted.app
+
+## Known Issues / Risks
+- **iOS review:** Yo was initially rejected for being "too simple" → have the context-based messaging explanation ready; keep copy clean.
+- **Harassment/spam:** Yo was hacked + spammed in 2014 → strict auth, no unauthenticated PII, rate limits + block (baked into API design).
+- **No business model killed Yo** → monetization is in from day one (ads + IAP).
+- iOS builds can't run on this Linux box → EAS cloud build (or a Mac) required.
+- Android push requires a Firebase project for FCM client credentials even with Expo Push API (secret `google-services.json`, injected at build).
+
+## Evolution Log
+- **2026-09-09 (s3)** — Git repo initialized & pushed: `git init -b main`, `README.md` + `.gitignore` added, memory-bank + .clinerules committed (`8fec909`), remote `2re/iFarted` on git.2re.top (public) populated via SSH key. Memory-bank updated to match.
+- **2026-09-09 (s1)** — Memory Bank initialized; requirements captured; stack recommendation (RN + Expo + TS) accepted.
+- **2026-09-09 (s2)** — Yo! app researched (`memory-bank/research/yo-app.md`); Bun feasibility answered (yes); decisions locked: identity = all three mechanisms, backend = Bun + Expo Push API, product = Yo-style context-based messaging with ephemeral farts. Memory-bank core files updated.

+# Project Brief — iFarted
+
+## Working Title
+**iFarted** (matches the working directory). Branding style follows **Yo!** (single word = the product). Final store name/icon/copy still TBD.
+
+## One-Liner
+A dead-simple cross-platform mobile app that lets a user send another user an **individual push notification** containing exactly the phrase **"I farted."** — optionally with the sender's current **location** attached. Modeled on the 2014 **Yo!** app (see `memory-bank/research/yo-app.md`).
+
+## Platform Targets
+- iOS (iPhone) — Apple App Store
+- Android — Google Play Store
+
+## Product Model (Yo! pattern — "context-based messaging")
+- The user **never types anything**. The single fixed message is "I farted."; meaning comes from context (who sent it, when, and where).
+- Recipient gets a push notification (text + custom audio sound) — the notification *is* the message. **No inbox/history/feed** (Yo-style ephemeral).
+- Home = recipient list; **tap a person → they get the fart**. Recipient can **one-tap fart back**.
+
+## Core Requirements (MVP)
+1. **Identity & discovery — ALL THREE mechanisms (user decision):**
+ a. Claim a unique *@username*; find others via **username search** + add.
+ b. Optional **phone number** on profile → **contacts matching** (opt-in only, privacy-safe matching server-side).
+ c. **Invite code + deep link** — sender generates one, friend opens it and is pre-connected.
+2. **Compose & send** — choose a recipient from your list, optionally toggle "attach my location," send the fixed phrase "I farted."
+3. **Delivery** — push notification to recipient: **title = sender's display name, body = "I farted."**, custom fart audio sound (mirrors Yo's text+audio alert). With location attached, tapping opens the app and shows a map pin of the sender.
+4. **Ads** — AdMob ads (default: banner on home; placement/frequency TBD).
+5. **Remove Ads IAP** — one-time **non-consumable** purchase that permanently removes ads, billed through StoreKit / Google Play Billing.
+
+## Backend (user decision)
+- **Lightweight server written in Bun** (Node-compatible runtime; "yes, Bun is possible") relaying through the **Expo Push API** (no Firebase Functions/Firestore, no raw APNs/FCM management server-side).
+- SQLite storage (Bun's `bun:sqlite`). Must be trivially runnable under plain Node too.
+
+## Non-Goals (MVP)
+- Message history/inbox/feed (ephemeral by design)
+- Group broadcasts, scheduled/recurring farts, reactions
+- Free-text chat or any content beyond the fixed phrase
+- Web/desktop clients
+- Accounts heavier than needed for reliable recipient targeting + push tokens
+
+## Monetization Model
+- **Free tier:** ads.
+- **Paid tier:** one-time Remove Ads IAP (non-consumable, permanent entitlement, restorable).
+- Yo died in 2016 for lack of revenue — monetization is in from day one.
+
+## Business/Policy Constraints to Respect
+- **No P2P push.** Delivery always routes backend → **Expo Push Service** → **APNs** (iOS) / **FCM** (Android).
+- Push must be **user-initiated and targeted** at a known recipient (anti-spam + store policy).
+- Location requires per-platform runtime permissions, iOS purpose strings, and store privacy disclosures.
+- Android still needs a **Firebase project** solely for FCM client credentials (`google-services.json`) even though the backend uses the Expo Push API.
+- iOS builds require macOS/Xcode or **EAS cloud build** + Apple Developer Program ($99/yr); Android requires Google Play Console ($25 one-time).
+- Remove Ads must be a genuine store-billed IAP — out-of-band payment for ad removal is grounds for rejection.
+- Yo was hacked (2014) exposing phone numbers + enabling Yo-spam → our API is auth'd end-to-end, PII-protected, and rate-limited (see systemPatterns).

+# Research Notes — "Yo!" (2014) and What We Copy for iFarted
+
+*Researched 2026-09-09. Sources: Wikipedia "Yo (app)" (current revision, 2026) + CNET article "The million-dollar app that exists to say 'Yo'" (June 19, 2014), retrieved via Wayback Machine.*
+
+## What Yo was
+- iOS/Android/Windows Phone app released **April 1, 2014** by Israeli developer **Or Arbel**, built in **~8 hours** at the request of Moshe Hogeg (Mobli CEO), who wanted a **single-button app** to "call" his assistant/wife without picking up the phone.
+- **Apple initially rejected it for being "too simple."** It exploded after appearing on Product Hunt. ~20k users in month one; 1M+ downloads by June 2014; 100M+ "Yos" sent by Sept 2014; ~$2.5M raised at a $5–10M valuation.
+- Company **shut down in 2016** ("autopilot"); later kept alive via Patreon (2018). **It never had a real business model** — the cautionary tale for our ad + IAP plan.
+
+## How it worked (verified quotes)
+- Wikipedia's feature summary is *almost word-for-word our user's brief*: **"The app enabled users to send individual notifications to other users, simply containing the word 'Yo'. Users could additionally send their location."**
+- Sending (CNET): **"You have a list of contacts. You tap one of those contacts, and they receive a notification saying simply, 'Yo', along with an audio alert of the word being spoken."**
+- Positioning (Arbel via NYT/CNET): **"We like to call it context-based messaging. You understand by the context what is being said."** The same "Yo" means good morning, "thinking about you", "meeting's over", "are you up?" depending on context.
+- **Addressing was by unique username** — e.g., a "worldcup" account yo'd followers whenever a team scored (later formalized via a public Yo API).
+- Evolution: Aug 2014 → profiles, links, hashtags. **Oct 2014 → send your location.** June 2015 v2 → photos or location **"within 1 swipe and a tap from the home screen"** + groups (yo several friends with one tap).
+- Notifications were **text + audio** (the word spoken aloud). No inbox/feed of messages — the notification *was* the message.
+
+## Failures / lessons (what NOT to repeat)
+1. **No monetization → died.** We monetize from day one: ads + one-time Remove Ads IAP.
+2. **June 2014 security hack** (Isaiah Turner): anyone could retrieve *any user's phone number* and spam/spoof Yos → we must: auth on every endpoint, never leak PII from unauthenticated lookups, unguessable tokens, per-sender rate limits, block path, abuse monitoring.
+3. **Apple review rejected "too simple"** → prepare a purpose/value explanation for App Review using the context-based messaging framing.
+4. **Novelty decays fast** → single-purpose is the hook; retention levers are the friend-connection flow and monetization, not features.
+
+## What we adopt ("do that")
+| Yo | iFarted adaptation |
+|---|---|
+| Single fixed word "Yo", zero typing | Single fixed phrase **"I farted."**, zero typing |
+| Push = "Yo" + audio alert | Push body "I farted." (+ sender display name); **custom audio notification sound** (iOS bundle sound <30s; Android notification-channel sound) |
+| Contact list, tap to send | Home = recipient list, tap → send; **one-tap "fart back"** after receiving |
+| Context-based messaging | Same framing: one phrase, meaning comes from context |
+| Username addressing | **All three** connection methods: username search · phone contacts (opt-in) · invite code/link |
+| Location attach (Oct 2014) | Per-message location toggle → map pin when recipient opens |
+| Groups (v2, 2015) | Post-MVP stretch feature |
+| No revenue model | AdMob ads + non-consumable Remove Ads IAP |
+
+## Copy/UX defaults derived from Yo (pending final wording)
+- Notification: **title = sender's display name, body = "I farted."**
+- Home: recipient list (recent first), big primary send action; empty state nudges "Add friends".
+- **No message history/inbox** — messages are the notifications themselves (ephemeral).
+- Primary onboarding: claim a unique *@username*; optionally verify phone for contact matching; invite via code/link.

+# System Patterns — iFarted
+
+## Target Architecture (user decisions locked: Bun backend + Expo Push API)
+
+```
+[Sender phone — iOS/Android, Expo/RN]
+ │ POST /v1/farts { recipientId, lat?, lng? } (Bearer apiKey)
+ ▼
+[Bun relay server] (TypeScript, Hono or plain fetch handlers, bun:sqlite)
+ │ auth + rate limit → insert message → call Expo Push API:
+ │ POST https://exp.host/--/api/v2/push/send
+ │ { to: , title: senderName,
+ │ body: "I farted.", sound: "fart.caf|mp3", data: {...} }
+ ▼
+[Expo Push Service] → [APNs / FCM]
+ ▼
+[Recipient phone] → OS notification → tap → in-app fart view (map pin if coords)
+```
+
+Guiding rules:
+- **No P2P push; no raw APNs/FCM on the server.** Bun talks only to the Expo Push API; Expo's service handles APNs/FCM. (Android still needs a Firebase project for the *client's* FCM token.)
+- Thin client, thin backend: client sends a tiny intent; backend validates, persists a stub, and relays; there is no inbox to serve.
+- Server must run identically under Bun or Node (keep bun-specific APIs optional so Node is a trivial fallback).
+
+## REST API (draft)
+| Endpoint | Purpose |
+|---|---|
+| `POST /v1/register` | Create user. Body: `{ username?, phoneE164?, inviteCode? }` → returns `{ userId, apiKey }`. Username claim is unique/case-insensitive; inviteCode pre-links. |
+| `POST /v1/tokens` | Register/refresh device push token `{ expoPushToken, platform }` (Bearer). |
+| `POST /v1/farts` | Send. Body: `{ recipientId, lat?, lng? }`. Server: check relationship+block list → rate limit → persist → Expo Push. Returns `{ ok, messageId }`. |
+| `GET /v1/users/search?username=` | Public lookup by username (returns only id/username/displayName — never phone). |
+| `POST /v1/contacts` | Body: `{ phoneE164: string[] }` → returns which of *my contacts* are users who enabled phone discovery. Contact numbers hashed/normalized server-side; not stored raw. |
+| `POST /v1/invites` | Create invite code for my username; client renders as code + deep link (exp:// / https link). |
+| `POST /v1/block` | Body `{ userId }` → stop receiving/sending. |
+
+## Mobile Client Patterns
+- **Navigation:** expo-router; flows = auth/onboarding, home(recipients), fart-detail(maps), settings.
+- **State:** React Context or Zustand. No Redux at MVP.
+- **Home data:** recipient list = contacts + people who sent you a fart (latest first, Yo-style), not a server inbox.
+- **Screens:** Onboarding (username/phone/invite) → Home (list + big send + location toggle + ad banner) → Send toast → Fart detail (+ map pin, one-tap **fart back**) → Settings (Remove Ads + Restore, sound toggle, phone-discovery toggle, account).
+- **Permissions:** notifications at first run with purpose text; location lazily via `expo-location` only when "attach location" tapped (iOS When-In-Use).
+- **Ads abstraction:** single gated `
+ inviteLink: string;
+}
+
+// Block
+export interface BlockRequest {
+ userId: UserId;
+}
+
+export interface BlockResponse {
+ ok: true;
+}
+
+// Rate limit / errors
+export interface ApiError {
+ error: string;
+ code?: string;
+ retryAfterMs?: number;
+}
+
+// Expo Push API relay (server → Expo)
+export interface ExpoPushMessage {
+ to: ExpoPushToken;
+ title: string; // sender display name
+ body: "I farted."; // fixed
+ sound?: string; // e.g. "fart.caf" / "fart.mp3" / default
+ data: FartPayload;
+ // optional:
+ badge?: number;
+ channelId?: string; // Android
+}
+
+export interface ExpoPushReceipt {
+ status: "ok" | "error";
+ id?: string;
+ message?: string;
+ details?: unknown;
+}

+
+ {displayFriends.map((f) => (
+
+
+ {f.displayName || f.username}
+ @{f.username} · {f.lastFart || f.lastFartAt || f.addedVia || "mock"}
+
+ sendFart(f)}>
+ {sending === f.id ? "..." : "💨 Fart"}
+
+
+ ))}
+
+
+ Home = recipient list ordered by most-recently active (Yo-style). No inbox/history. One-tap fart back on detail + map pin if location attached.
+
+ {log.length > 0 && (
+
+ {log.map((l, i) => (
+ {l}
+ ))}
+
+ )}
+
+ Context-based messaging: "You understand by the context what is being said." — Or Arbel (Yo creator). Apple once rejected Yo for being "too simple" — this framing is our App Review explanation.
+
+
+ Try: register → search → add friend → tap 💨 Fart → check server metrics + logs. Sound plays on tap (fart.mp3).
