Arnaud 362f65656b fix: audit fixes — tier-quota bypass, webhook SSRF, auth hardening, pagination, a11y
Full audit (bugs/UI-UX/backend/feature-gap) turned up a money-leak AI quota
bypass, webhook SSRF, and a long tail of missing pagination/auth/a11y work.
Fixes land together since HANDOFF.md tracked them as one backlog.

- AI routes charge tier quota before generating; nutrition POST is author-only
- Webhook dispatch re-validates URL per delivery (SSRF/DNS-rebinding), treats
  redirects as failures; recipe.published now actually dispatches
- New indexes/unique constraints on recipes, meal-planning, comments FK cascade
- Recipe PUT/restore snapshot only inside the transaction, after validation
- Recipe DELETE cleans up S3 objects (recipe + review photos)
- Optimistic UI (favorite/star/follow/shopping-list) rolls back on failure
- Upload presign enforces file size cap + per-tier storage quota
- Route-level loading/error/not-found states across (app), admin, and root
- middleware.ts guards (app)/admin; requireAdmin checks DB role, not cached
  session; rate limiting applied to both session and API-key branches,
  bucketed per key; Stripe webhook dedupes by event id
- Pagination added to recipes, feed, profile, comments, pantry, admin tables
- Nav shows real avatar + profile link + dark-mode toggle; destructive actions
  standardized on AlertDialog
- Unsaved-changes guard + real ingredient/step validation on recipe form;
  canonical /recipes/[id] used in-app; next/image migration; aria-labels and
  alt text across icon buttons, avatars, recipe photos
- packages/api-types removed (zero callers, too drifted to safely rewire);
  openapi.ts and ai-keys error shape drift fixed; BYOK decrypt failures now
  surface instead of silently falling back to the platform key

# CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
## Dev Setup
```bash
cp .env.example .env.local # fill in secrets (lives at repo root)
ln -s ../../.env.local apps/web/.env.local # Next.js reads from apps/web/, not root
docker compose -f docker/compose.yml up -d # start postgres, redis, minio
pnpm install
pnpm db:generate # generate migrations from schema (first time)
pnpm db:migrate # apply migrations
pnpm db:seed # seed tier definitions
pnpm dev # start Next.js on :3000
```
MinIO console: http://localhost:9001 (minioadmin / minioadmin)
## Key Commands
```bash
pnpm dev # run web app
pnpm build # production build
pnpm lint # lint all packages
pnpm typecheck # type-check all packages
pnpm db:generate # generate Drizzle migration from schema changes
pnpm db:migrate # apply migrations
pnpm db:seed # seed tier definitions
pnpm db:studio # open Drizzle Studio
```
## Architecture
**Monorepo** (pnpm workspaces):
- `apps/web` — Next.js 15 App Router app (`@epicure/web`)
- `packages/db` — Drizzle ORM schema + client (`@epicure/db`)
**Route groups in `apps/web/app/`**:
- `(auth)/` — login, signup, verify-email (no auth required)
- `(app)/` — main app shell with nav (auth required)
- `admin/` — admin-only, role checked in layout server component
- `api/v1/` — REST API endpoints
- `api/auth/[...all]/` — Better Auth handler
**Auth**: Better Auth with Drizzle adapter. Server: `lib/auth/server.ts`. Client: `lib/auth/client.ts`. Middleware at `middleware.ts` guards all routes.
**DB**: Drizzle ORM on Postgres. Schema in `packages/db/src/schema/` split by domain: `users`, `recipes`, `social`, `meal-planning`, `tiers`. Import from `@epicure/db`.
**AI** (Phase 3): Vercel AI SDK provider factory in `apps/web/lib/ai/`. All AI outputs use `generateObject` + Zod schemas — no free-text parsing.
**Storage**: S3-compatible via `STORAGE_*` env vars. MinIO locally, any S3-compatible provider in prod.
**Tier limits**: `lib/tiers.ts` exports `checkTierLimit(userId, tier, key)` — call before recipe create and AI calls. Throws `TierLimitError` on breach.
## Adding a shadcn/ui Component
```bash
cd apps/web && pnpm dlx shadcn@latest add <component-name>
```
## Schema Changes
1. Edit `packages/db/src/schema/*.ts`
2. `pnpm db:generate` — creates migration file
3. `pnpm db:migrate` — applies it
4. Update the corresponding inline Zod schemas in the affected `apps/web/app/api/v1/**/route.ts` files (and `apps/web/lib/openapi.ts` if documented there)
## Environment Variables
See `.env.example`. Required for dev: `DATABASE_URL`, `BETTER_AUTH_SECRET`, `BETTER_AUTH_URL`. AI keys optional until Phase 3.
