## What this repo is

- **Pure frontend** — Next.js 16 App Router, TypeScript, server components +
  client components, deployed to Vercel.
- **Talks to a Python backend** at `https://api.trumpsignal.com` (or
  `localhost:8000` in dev). All trading state, signals, AI scoring,
  Hyperliquid integration lives in the sibling **`/Users/k/Public/Claude/
  backend`** repo. See its CLAUDE.md.
- **No server-side trading logic** lives here. Frontend is a thin layer
  over the API + WebSocket — even "open a position" routes to a backend
  endpoint that does the signed-request verification + HL call.

---

## Stack quirks (Next.js 16 specific)

- **`proxy.ts` replaces `middleware.ts`** in Next.js 16. Routes that need
  CORS / locale rewriting go through `proxy.ts` at the root.
- **`params` is async (`Promise<{...}>`)** in all dynamic routes. ALL page
  components await it:
  ```tsx
  export default async function Page({ params }: { params: Promise<{ locale: string }> }) {
    const { locale } = await params
    ...
  }
  ```
  Forgetting the `await` redirects to `/undefined/...` silently. Several
  pages were broken this way pre-v2.0 — be alert if you copy older patterns.
- **i18n is shelved.** The `[locale]` segment exists, `messages/zh.json`
  exists, but Chinese branches are kept as dead code with a comment
  `// i18n shelved — see messages/zh.json`. Don't activate without an ADR.
  Currently `isZh = false` is hardcoded in metadata generators.
- **`runtime = 'edge'`** on a few routes (`app/icon.tsx`, OG image generator).
  Edge runtime has no fs / no Node APIs — don't import server-side libs there.

## API layer

All API calls go through **`lib/api.ts`**. Single `fetchJson<T>` wrapper:

- Reads base URL from env (`NEXT_PUBLIC_API_URL`) or proxies through
  `/api/proxy/[...path]/` for same-origin CORS-free calls.
- Wallet-scoped reads (`/user/.../public`, `/positions/open`) pass wallet
  as query param + signed ts/sig.
- Mutations (subscribe, manual_close, set_auto_trade, manual-window) build
  an EIP-191 signed payload via wagmi → POST signed envelope.

**Auth model**: no sessions, no cookies. Wallet address + signed timestamp
+ signature on every mutating call. Verification lives in the backend
(`signed_request.verify_signed_request`). The same wallet that signed the
HL API key envelope at subscribe time is the only one that can later
mutate the subscription.

---

## State management

- **No global store** (no Redux/Zustand). Tree-local state + props.
- **SWR-style cache** in `lib/cache.ts` for the API-heavy pages.
- **WebSocket** singleton via `WsProvider` — used by `SignalMonitor` and
  live price tickers.
- **localStorage** holds wallet address only (for re-connect UX). HL API
  keys NEVER touch the client — they're submitted once at subscribe, sent
  encrypted, and decrypted only inside the backend.

---

## Design system

Tokens in `app/[locale]/globals.css`:

- **Colors** — `oklch()` color space throughout. Brand orange = `#f5a524`,
  brand dark = `#0a0907`. `var(--up)` green / `var(--down)` red / `var(--ink-1..3)`
  text tiers.
- **Dark mode** via `[data-theme="dark"]` attribute on `<html>`. Most
  components use `oklch(L% c h)` so dark/light switching is automatic.
- **Macro Vibes specific** — extensive `.macro-*` classes for the 8-indicator
  layout. Threshold chips have `:not(.active) { opacity: 0.45 }` and `.active`
  is tone-filled (green/red/amber).

---

## Things that LOOK like bugs but aren't

- **Old code references "/en/btc"** — Macro Vibes was renamed from "BTC
  Signal" in v2.0. All routes are now `/en/macro`. If you find a stale
  `/en/btc` reference, it's a real bug — fix it (we've found and fixed 3).
- **`isZh = false` in metadata generators** — i18n was shelved pre-launch.
  See "Stack quirks" above.
- **Multiple `proxy.ts` patterns** — Next.js 16 split middleware behaviour.
  Keep proxy logic in the single `proxy.ts` at root.
- **`'use client'` directives on many pages** — necessary for client-side
  WS / wallet interactions. Don't try to convert without verifying the WS
  + wagmi imports work in server components.

## How to verify changes locally

```bash
# Type check (must pass with 0 errors)
npx tsc --noEmit

# Production build (catches missing pages, stale imports)
rm -rf .next && npx next build

# Dev server
npm run dev

# Pages-200 sweep (every locale page returns 200)
for p in /en /en/trump /en/macro /en/kol /en/trades /en/posts /en/settings \
         /en/methodology /en/glossary /en/case-studies /en/privacy /en/terms; do
  echo "$p $(curl -so /dev/null -w '%{http_code}' http://localhost:3000$p)"
done
```

## SEO / GEO surface (don't break)

- **`app/layout.tsx`** has JSON-LD schema.org markup (Organization,
  SoftwareApplication, FAQ). Search engines + AI crawlers read this.
- **`public/llms.txt`** — canonical doc for AI crawlers (Perplexity, ChatGPT
  browse, Google AI Overviews). Edit BOTH this file AND `layout.tsx` when
  renaming product features.
- **`app/sitemap.ts`** — sitemap.xml. Add new routes here.
- **OG image** — `app/opengraph-image.tsx` dynamically renders the social
  card. Keep the brand pill list in sync with current features.

---

## Coupling to backend

- **API contract lives in TypeScript types under `lib/api.ts`** (e.g.
  `OpenPositionsResponse`, `TodayStats`, `BotTrade`). These must match the
  backend Pydantic models in `app/api/*/positions.py` etc.
- When backend adds a field (e.g. `BotTrade.released_at`), this repo's
  `lib/api.ts` types may need updating to surface it in the UI. Currently
  released trades are FILTERED OUT by the backend's `/positions/open` —
  they don't appear here, so no UI for "managed vs released" yet.
- When backend renames a route (e.g. `/btc/page.tsx` → `/macro/page.tsx`),
  search for ALL references (including telegram deep-link map in
  `backend/app/services/telegram.py`).

## Deploy

Vercel auto-deploys `main` branch pushes. No special build flags. Env vars
in Vercel dashboard:
- `NEXT_PUBLIC_API_URL` — backend HTTPS origin
- `NEXT_PUBLIC_SITE_URL` — canonical site URL (used for OG, sitemap)
- `NEXT_PUBLIC_WS_URL` — WebSocket endpoint (usually `wss://api...`)

---

## Sibling repo

- **`/Users/k/Public/Claude/backend`** — Python/FastAPI backend, includes
  Hyperliquid integration, Telegram bot, AI scoring (DeepSeek), all
  signal scanners, the adoption/release flow. See its CLAUDE.md.
