 # CLAUDE.md
 
-This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+Tia - Baby Tracking App. Next.js 16, PostgreSQL, offline-first.
 
-## Project Overview
+## Build Rule
 
-**Tia** is a baby tracking app built with Next.js 15/16, designed for a Mama to track her baby's feeds, sleep, diapers, vaccinations, growth, and memories. The app features offline-first logging, AI-powered Q&A, and a Telegram alert system.
+**ALWAYS run `npm run build` before pushing.** Fix errors locally first.
 
-## Build Verification Rule
+## Project Status
 
-**ALWAYS verify the build passes locally BEFORE asking user to deploy.** Run `pnpm build` (or `npm run build`) and confirm it succeeds with no errors. Do not ask the user to trigger a deployment until you've confirmed the build works.
+- ✅ Fast-log (feed/sleep/diaper + offline queue)
-
+- ✅ PWA manifest + service worker
-## Common Commands
+- ✅ Vaccinations (IAP schedule)
-
+- ✅ Growth tracking
-```bash
+- ✅ Memories gallery (placeholder)
-# Development
+- ✅ AI chat (LiteLLM)
-pnpm dev              # Start local dev server
+- ✅ Dark mode toggle
-pnpm build             # Production build
+- ✅ Menu navigation
-npm ci                # Clean install for Docker
+- ⏳ Cloudflare R2 upload (needs credentials)
-
+- ⏳ Telegram alerts
-# Database (Drizzle)
-npx drizzle-kit generate  # Generate migration from schema
-npx drizzle-kit push    # Push schema to DB
-```

-## Environment Variables
-
-Required in `.env.local`:
-
-```env
-DATABASE_URL=postgresql://tia:tia_local_dev@localhost:5433/tia_dev
-AUTH_SECRET=
-AUTH_URL=http://localhost:3000
-RESEND_API_KEY=

-## Hits & Learned Lessons
-
-### Build Issues Fixed
-1. **pnpm 11 + Node 20 incompatibility**: pnpm 11 requires Node 22+. Fixed by using Node 22 in Dockerfile.
-2. **pnpm ignored builds in Docker**: Had to switch from pnpm to npm in Dockerfile (`npm ci` instead of `pnpm install`).
-3. **Drizzle adapter type errors**: Using simplified DrizzleAdapter without passing table configs directly fixes type errors.
-4. **nodemailer missing**: NextAuth email provider requires nodemailer as a dependency.
-5. **Middleware warning**: Next.js 16 shows deprecation warning for middleware file convention.
-
-### Database Setup
-- Local: Docker Compose with pgvector on port 5433, Redis on 6380
-- Schema: 8 tables (users, accounts, sessions, verification_tokens, families, family_members, children, family_invites)
-- Migrations: Run via `npx drizzle-kit push` or docker exec with SQL files
-
-### Docker Build
-- Use `npm ci` instead of pnpm in Docker for reliability
-- Node 22 alpine image
-- Multi-stage build (deps → builder → runner)
-- Need to install nodemailer separately for email auth
-
-## Architecture
-
-- **Framework**: Next.js 16 (App Router) with TypeScript
-- **Database**: PostgreSQL 16 with pgvector (Drizzle ORM)
-- **Auth**: NextAuth v5 beta
-- **Deployment**: Dokploy (Docker)
-
-## Sprint Plan
-
-Current: Sprint 1 (Database + Auth)
-
-- Sprint 0: Dev environment, Docker, Dokploy deploy ✅
-- Sprint 1: Auth + Database with RLS (in progress)
-- Sprint 2: Fast-log engine
-- Sprint 3: Medical vault
-- Sprint 4: Media pipeline
-- Sprint 5: AI Brain
-- Sprint 6: UI/UX polish
-- Sprint 7: Telegram alerts + launch

+## Conventions
+
+### API Pattern
+```typescript
+// GET with query params, POST with JSON body
+export async function GET(request: Request) {
+  const { searchParams } = new URL(request.url);
+  const id = searchParams.get("id");
+  // use sql.unsafe() for raw queries
+}
+export async function POST(request: Request) {
+  const body = await request.json();
+  // use sql.unsafe() with parameterized values
+}
+```
+
+### UI Pattern
+```typescript
+"use client";
+import { useState, useEffect } from "react";
+// dark mode: document.documentElement.classList.toggle("dark")
+// links: use <Link href="..."> not router.push()
+```
+
+### Database
+- Use `sql.unsafe()` not `db.execute()` - postgres-js method
+- Dates: `new Date().toISOString()` string format
+- Enums: create manually, no IF NOT EXISTS support
+
+## Local Dev
+
+```bash
+cd tia
+npm run dev
+```
+
+## Deployment
+
+Auto-deploys via webhook on Git push. Database tables created via `/api/setup`.
+
+## Environment
+
+```
+DATABASE_URL=postgresql://user:pass@host:5432/db
+OPENAI_API_BASE_URL=http://litellm-gateway:4000/v1
