- RiskManager halts + flattens on max daily loss / drawdown, caps position size and trades per day; adds a manual kill switch (POST /api/bot/kill). - Telegram and webhook notifications on trades, errors and halts. - Optional API bearer token on /api, injected server-side by the frontend nginx so the browser never sees it. - Kraken and Coinbase market data (public); Coinbase live broker. Live on an unsupported exchange now errors instead of silently falling back to paper. - Strategy presets backed by the StrategyConfig table (CRUD API + UI). - Idempotent additive-column migration so existing SQLite databases upgrade in place (fixes the new strategy_configs.name column).
