## 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`. `app/[locale]/btc/page.tsx`
  EXISTS intentionally as a permanent redirect to `/en/macro` — that's fine.
  If you find a stale `/en/btc` hardcoded link anywhere else, it's a real
  bug — fix it.
- **`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.
- **`telegram.send_message` accepting `int | str` for chat_id** — the backend
  uses string form for the public channel (`"@trumpalpha"`) and integer for
  private user chats. Both are valid; no frontend change needed.
- **`x-forwarded-for` is deleted in the proxy** — KNOWN BUG (see below).
  Don't "fix" it by just removing the delete; the correct fix is to relay the
  real client IP. See Open Known Issues.

---

## Open known issues (frontend)

- ~~**Rate limit bypass via proxy** (FIXED 2026-05-29):~~ `route.ts` no longer
  deletes `x-forwarded-for`. It now reads the real client IP from the incoming
  `x-forwarded-for` or `x-real-ip` header (set by Vercel/CDN) and sets it on
  the upstream request so `slowapi` can distinguish individual clients.

- ~~**`signMessageAsync` in `OpenPositions` polling deps** (MEDIUM, FIXED 2026-05-29):~~
  Removed `signMessageAsync` and `isZh` from the `useEffect` dependency array
  in `components/positions/OpenPositions.tsx`. Neither is used inside the effect;
  including them caused wagmi reference churn to restart the 15s poll timer.

- ~~**Stale types after BUG-08/BUG-14** (FE-01–06, FIXED 2026-05-29):~~
  - `types/index.ts`: `price_impact.asset` widened from `'BTC' | 'ETH'` to
    `string` (BUG-14 now tracks the actually-traded asset which may be
    SOL/TRUMP/etc.).
  - `lib/useRealtimeData.ts`: `PriceMsg.asset` and `Handlers.onPrice` widened
    to `string` (BUG-08 expanded the WS price stream to all ASSET_MAP entries).
  - `store/dashboard.ts`: `livePrices` changed from `{ BTC; ETH }` to
    `Record<string, number | null>`; `setLivePrice` param widened to `string`.
  - `lib/api.ts`: `getPrices` asset param widened to `string`.
  - `components/trades/TradeTable.tsx`: hardcoded `ASSETS = ['all','BTC','ETH','SOL']`
    replaced by a dynamic `useMemo` that builds the asset list from the actual
    trade set — new perps (TRUMP, BNB, etc.) appear in the filter automatically.
  - `DashboardClient.tsx` + `TradesPageClient.tsx`: removed `isZh` from
    `useEffect` deps (compile-time constant; including it restarted effects
    on every render).

- ~~**Interaction/button bugs sweep** (UI-A..G, FIXED 2026-05-29):~~
  - **A** `OpenPositions.tsx` close-modal backdrop now dismisses in `'err'`
    state too (previously stuck — only `'idle'` dismissed). State is reset on
    dismiss so the next open is clean.
  - **B** `confirmCloseTrade` distinguishes user-cancelled signature
    (`isUserRejection`) from real failure: cancellation closes the modal
    silently; real errors stay open in `'err'` state with the message.
  - **C** `SystemControl.flipAuto` claims `busy=true` **before** `await
    confirmSign(...)`. Rapid double-click on the ON/OFF pill no longer slips
    past the guard. The slot is released if the user cancels the sheet.
  - **D** `BotConfigPanel` "Rotate" API-key button resets `keyState`/`keyErr`
    so a previously-failed save's red error doesn't bleed into the new edit.
  - **E** Paper/Live `Switch` clears `subErr` when toggled so a stale
    subscribe-error doesn't sit next to the new choice.
  - **F** `confirmSign` keeps a module-scope `_activeCancel`; a second call
    while a sheet is mounted resolves the first promise with `false` instead
    of leaving its caller hanging forever. All 9 call sites verified to
    cleanly handle the `false` return (`setBusy(false)` / `setLoadState('idle')`).
  - **G** `OpenPositions.toggleGrow` errors now write to a dedicated
    `growErr` state with a 4-second auto-clear, instead of squatting in the
    panel-header `err` banner shared with the 15-s poll error.

## 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)

  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`).
