BigBodyCobain b041b5e97c Fix #298: move Sentinel credentials from browser storage to backend .env
Reported by @tg12. Pre-fix, the Settings panel stored real third-party
Copernicus CDSE client_id + client_secret in browser localStorage /
sessionStorage via the privacy storage helper, and the proxy routes
required those values to come back in every tile/token request body.
Any same-origin script (XSS, malicious browser extension, dev-tools
HAR export) had read access to the credentials.

This change moves them server-side, behind the same .env-backed admin
flow every other third-party API key (OpenSky, AIS Stream, Finnhub,
Shodan, …) already uses.

Backend
-------
backend/services/api_settings.py
  * Added SENTINEL_CLIENT_ID and SENTINEL_CLIENT_SECRET entries to
    API_REGISTRY. The existing GET/PUT /api/settings/api-keys flow
    (already require_local_operator-gated, .env-backed) now manages
    them — no new route surface.

backend/routers/tools.py
  * /api/sentinel/token and /api/sentinel/tile resolve credentials via
    a new _resolve_sentinel_credentials() helper: body fields win for
    back-compat with any legacy callers, otherwise the helper reads
    SENTINEL_CLIENT_ID / SENTINEL_CLIENT_SECRET from os.environ.
  * When neither source has a value, the route returns 400 with a
    friendly pointer ("Set SENTINEL_CLIENT_ID and SENTINEL_CLIENT_SECRET
    in the API Keys panel") instead of the curt "required" message.
    The user's standing rule against hostile errors applies.
  * Function bodies only — decorator lines untouched, so this PR does
    not conflict with #303 (which adds Depends(require_local_operator)
    to the same routes).

Frontend
--------
frontend/src/lib/sentinelHub.ts — rewritten
  * Removed: getSentinelCredentials / setSentinelCredentials /
    clearSentinelCredentials / getSentinelCredentialStorageMode.
    These were the browser-storage read/write helpers; their existence
    was the bug.
  * Added: checkBackendSentinelStatus(), refreshSentinelStatus(),
    getCachedSentinelStatus(), and a kept-for-back-compat
    hasSentinelCredentials() shim. Status is sourced from
    /api/settings/api-keys (the same endpoint the API Keys panel
    already uses), so we don't add a new route just for this read.
  * Added: migrateLegacySentinelBrowserKeys() — one-shot, idempotent
    helper that clears sb_sentinel_client_id / _secret / _instance_id
    from BOTH localStorage and sessionStorage. We deliberately do NOT
    auto-POST those legacy browser values to the backend; doing so
    would silently migrate a secret across a trust boundary without
    operator consent. Operators re-enter once in the API Keys panel
    and the legacy keys get wiped here.
  * fetchSentinelTile and getSentinelToken no longer send client_id /
    client_secret in the request body. The backend uses .env.

frontend/src/components/SettingsPanel.tsx
  * Dropped sb_sentinel_client_id / _secret / _instance_id from
    PRIVACY_SENSITIVE_BROWSER_KEYS — they're no longer written.
  * SentinelTab rewritten: removed the inline Client ID / Client Secret
    inputs + Save / Clear / Test buttons. Replaced with a status panel
    that calls checkBackendSentinelStatus() on mount, a one-click
    "Open API Keys Panel" button, and a migration banner that appears
    only when migrateLegacySentinelBrowserKeys() actually cleared
    something.
  * Setup guide STEP 3 now points to the API Keys panel instead of
    the local form.

frontend/src/app/page.tsx
  * Added a one-time useEffect that fires checkBackendSentinelStatus()
    on mount so the cached value (which the synchronous
    hasSentinelCredentials() shim reads) is populated before
    MaplibreViewer's tile-URL memo runs.

Tests
-----
backend/tests/test_sentinel_credentials_server_side.py (new)
  * API_REGISTRY surface — sentinel_client_id / sentinel_client_secret
    are registered with the right env_keys, ALLOWED_ENV_KEYS lets
    /api/settings/api-keys PUT them.
  * Resolution order — body wins, env is fallback, neither → 400 with
    the friendly pointer message, and NO upstream HTTP call when
    neither source has credentials (asserted via
    MagicMock(side_effect=AssertionError)).
  * /api/sentinel/tile same shape.

frontend/src/__tests__/utils/sentinelHub.test.ts (new)
  * migrateLegacySentinelBrowserKeys clears localStorage AND
    sessionStorage, reports what it cleared, idempotent.
  * fetchSentinelTile + getSentinelToken POST WITHOUT client_id /
    client_secret in the body (plants leaked credentials in browser
    storage first to prove they are NOT picked up).
  * checkBackendSentinelStatus parses /api/settings/api-keys correctly:
    true only when both keys is_set, false on partial config or
    network errors.

All 7 backend tests + 8 frontend tests pass locally. The
test_no_new_duplicate_routes guard and the api-settings test suite
still pass.

ShadowBroker Frontend

Next.js 16 dashboard with MapLibre GL, Cesium, and Framer Motion.

Development

npm install
npm run dev        # http://localhost:3000

API URL Configuration

The frontend needs to reach the backend (default port 8000). Resolution order:

  1. NEXT_PUBLIC_API_URL env var — if set, used as-is (build-time, baked by Next.js)
  2. Server-side (SSR) — falls back to http://localhost:8000
  3. Client-side (browser) — auto-detects using window.location.hostname:8000

Common scenarios

Scenario Action needed
Local dev (localhost:3000 + localhost:8000) None — auto-detected
LAN access (192.168.x.x:3000) None — auto-detected from browser hostname
Public deploy (same host, port 8000) None — auto-detected
Backend on different port (e.g. 9096) Set NEXT_PUBLIC_API_URL=http://host:9096 before build
Backend on different host Set NEXT_PUBLIC_API_URL=http://backend-host:8000 before build
Behind reverse proxy (e.g. /api path) Set NEXT_PUBLIC_API_URL=https://yourdomain.com before build

Setting the variable

# Shell (Linux/macOS)
NEXT_PUBLIC_API_URL=http://myserver:8000 npm run build

# PowerShell (Windows)
$env:NEXT_PUBLIC_API_URL="http://myserver:8000"; npm run build

# Docker Compose (set in .env file next to docker-compose.yml)
NEXT_PUBLIC_API_URL=http://myserver:8000

Note: This is a build-time variable. Changing it requires rebuilding the frontend.

Theming

Dark mode is the default. A light/dark toggle is available in the left panel toolbar. Theme preference is persisted in localStorage as sb-theme and applied via data-theme attribute on <html>. CSS variables in globals.css define all structural colors for both themes.
