PR Compliance Guide 🔍

(Compliance updated until commit 063f880)

Below is a summary of compliance checks for this PR:

Security Compliance
⚪	Weak CSP policy Description: The configured Content-Security-Policy allows 'unsafe-inline' for scripts and styles and whitelists external CDNs, which weakens XSS protections and may allow script injection; consider using nonces/hashes and removing 'unsafe-inline'. main.py [142-159] Referred Code response.headers["Content-Security-Policy"] = ( "default-src 'self'; " "script-src 'self' 'unsafe-inline' https://cdn.jsdelivr.net https://cdn.socket.io; " "style-src 'self' 'unsafe-inline'; " "img-src 'self' data: https:; " "connect-src 'self' ws: wss:; " "font-src 'self'; " "object-src 'none'; " "base-uri 'self'; " "form-action 'self';" ) # Autres headers de sécurité response.headers["X-Content-Type-Options"] = "nosniff" response.headers["X-Frame-Options"] = "DENY" response.headers["X-XSS-Protection"] = "1; mode=block" response.headers["Referrer-Policy"] = "strict-origin-when-cross-origin"
	API key auth risks Description: API key authentication is added to start/stop routes but using a static API key scheme can be susceptible to leakage or reuse without rate limiting or audit; ensure keys are securely stored, rotated, and requests are rate-limited. dashboard.py [171-259] Referred Code 'timestamp': time.time() }, status_code=200) # Retourner 200 avec success=False au lieu de 500 @router.post("/start") async def start_scanner(user: dict = Security(verify_api_key)): """ POST /api/start Démarrer le scanner et le scheduler Nécessite authentification (X-API-Key header) Procédure: 1.

	Preserve UI state on temporary disconnects Remove the immediate clearing of trade history and session stats on WebSocket disconnect to prevent data loss during temporary network issues and improve user experience. frontend/src/routes/+page.svelte [216-225] ws.on('disconnect', async () => { console.warn('⚠️ WebSocket déconnecté'); backendConnected = false; - // 🔥 FIX: Reset trades à la fermeture du backend - const { clearHistory } = await import('$lib/stores/trades'); - clearHistory(); - // 🔥 FIX: Reset stats session - const { resetSessionStats } = await import('$lib/stores/stats'); - resetSessionStats(); + // Données de session ne sont plus effacées ici. + // La logique de reconnexion tentera de restaurer l'état. + // Les données ne seront effacées que lors d'un rechargement de page + // ou si le backend signale une nouvelle session. }); Apply / Chat Suggestion importance[1-10]: 7 __ Why: The suggestion correctly identifies a poor user experience where temporary disconnects clear session data, and it proposes preserving the state to allow the built-in reconnection logic to work seamlessly.

General	Add assertion to verify behavior Add an assertion to test_scalability_refresh_with_active_position to verify that the scanner's scan_top_pairs method is not called when a position is active. tests/test_callbacks.py [288-309] @pytest.mark.asyncio async def test_scalability_refresh_with_active_position(self): """Test callback avec position active (devrait être ignoré)""" from core.callbacks import scalability_refresh mock_position = Mock() mock_pm = Mock() mock_pm.active_position = mock_position - mock_scanner = Mock() + mock_scanner = AsyncMock() mock_state = { "is_scanning": True, "active_position": {"symbol": "BTC/USDT:USDT"} } scalability_refresh._scanner = mock_scanner scalability_refresh._position_manager = mock_pm scalability_refresh._app_state = mock_state await scalability_refresh.scalability_refresh_loop_callback() # Scanner ne devrait PAS être appelé (position active) + mock_scanner.scan_top_pairs.assert_not_called() Apply / Chat Suggestion importance[1-10]: 7 __ Why: The suggestion correctly identifies a test that is ineffective due to a missing assertion and provides a fix, which significantly improves the quality and reliability of the test suite.

	Improve test cleanup logic robustness Replace os.rmdir with the more robust shutil.rmtree in teardown_method to ensure the temporary test directory is always cleaned up correctly. tests/test_database.py [20-26] def teardown_method(self): """Cleanup après chaque test""" - # Supprimer le fichier DB temporaire - if os.path.exists(self.db_path): - os.remove(self.db_path) + # Supprimer le répertoire temporaire et son contenu + import shutil if os.path.exists(self.temp_dir): - os.rmdir(self.temp_dir) + shutil.rmtree(self.temp_dir) Apply / Chat Suggestion importance[1-10]: 6 __ Why: The suggestion correctly identifies a potential point of failure in the test cleanup logic and proposes using shutil.rmtree for a more robust implementation, improving test suite stability.
