bd3d532239 feat: real SSE streaming for agent chat + data cleanup on startup 
SSE Streaming:
- Add POST /api/agent/chat/stream endpoint with real SSE streaming
- Agent.HandleMessageStream() streams final LLM response via onEvent callback
- Tool-calling rounds use non-streaming; tool status sent as 'tool' events
- Frontend uses ReadableStream API instead of fake word-by-word setTimeout
- SSE events: tool (tool execution), delta (text chunk), done (complete), error

Data Maintenance:
- Add cleanupOldData() on server startup (decisions >90d, equity >180d)
- Add CleanOldRecords to DecisionStore and EquityStore
- Add store-level logger for cleanup operations

Exchange Traders:
- Add GetAccountInfo() to Bitget, Bybit, Indodax, KuCoin, Lighter, OKX traders
- Remove unused imports in Aster/Lighter traders

54dce726cb feat: dynamic crypto detection, trade history tool, fix 9 ticker leaks 
- Agent gatherContext: expand from 10 hardcoded symbols to 38+ known symbols
  plus dynamic XXXUSDT pattern extraction (caps at 5 to avoid slow context)
- Add get_trade_history tool: LLM can now query closed trades with PnL summary
  (win rate, total PnL, recent N trades across all traders)
- Fix ticker.Stop() leak in ALL 9 exchange order_sync goroutines:
  OKX, Hyperliquid, Aster, Bybit, KuCoin, Gate, Bitget, Lighter, Binance
  — tickers were never stopped when traders were stopped, leaking goroutines

acc52f2cf7 fix: prevent panics from unsafe type assertions in trading code + add request body limit 
Security & Reliability:
- Add requestBodyLimitMiddleware (1MB) to prevent OOM from oversized API payloads
- Fix defer resp.Body.Close() inside loop in getPublicIPFromAPI (connection leak)
- Add posFloat64/posString safe helpers for position map access

Panic Prevention (critical for trading):
- Convert 30+ unsafe type assertions (pos["key"].(type)) to safe comma-ok
  pattern across all exchange traders: OKX, Hyperliquid, Aster, Bybit,
  KuCoin, Gate, Bitget, Binance
- Fix auto_trader_risk.go: drawdown monitor could panic and silently stop
  monitoring, leaving positions unprotected
- Fix auto_trader_decision.go & auto_trader_loop.go: core trading loop
  position parsing now crash-proof
- All trader/ code now has zero unsafe type assertions

Frontend:
- Fix config.ts: rejected promise cached forever on network error (never retries)

bb459d6f9f fix: Bybit shared HTTP client, auth token bugs, consistent safe.ReadAllLimited 
- Bybit: replace http.Get/http.DefaultClient with shared bybitHTTPClient (30s timeout, connection pooling)
- Frontend: fix resetPassword missing auth token (endpoint now requires auth)
- Frontend: fix SettingsPage using wrong localStorage key ('token' → 'auth_token')
- Agent: migrate remaining io.ReadAll(io.LimitReader()) to safe.ReadAllLimited for consistency
- Remove unused 'io' imports from brain.go and sentinel.go

982ee668c9 security: add safe.ReadAllLimited — bound all HTTP response body reads to 10MB 
- Created safe/io.go with ReadAllLimited helper (default 10MB limit)
- Replaced 62 unbounded io.ReadAll(resp.Body) calls across 32 files
- Covers all exchange traders (Hyperliquid, Bybit, Binance, OKX, Aster,
  KuCoin, Gate, Bitget, Lighter, Indodax), providers (CoinAnk, Alpaca,
  TwelveData), MCP client/x402, market data, wallet, telegram, kernel
- Prevents OOM from malicious/buggy exchange API responses
- Previously fixed: brain.go, sentinel.go already had manual LimitReader

5e06037fa2 reliability: wrap all 27 bare goroutines with safe.Go/GoNamed panic recovery 
Applied safe.GoNamed to:
- 9 exchange order_sync goroutines (OKX, Hyperliquid, Aster, Bybit, KuCoin, Gate, Bitget, Lighter, Binance×2)
- Drawdown monitor (auto_trader_risk.go)
- Brain news scanner + market briefs (agent/brain.go)
- Sentinel scanner (agent/sentinel.go)
- Agent scheduler (agent/scheduler.go)
- x402 idle watchdog (mcp/payment/x402.go)
- MCP stream idle watchdog (mcp/client.go)
- Rate limiter cleanup (api/rate_limiter.go)
- 3 telemetry fire-and-forget sends (telemetry/experience.go)
- CoinAnk WS handler (provider/coinank/coinank_api/kline_ws.go)
- API server goroutine (main.go)

Added manual defer/recover with error reporting to:
- Telegram AI agent handler (sends error msg to user on panic)
- Trader data fetch (returns error result on panic to prevent deadlock)

Before: a panic in ANY of these 27 goroutines would crash the entire
trading process with zero diagnostics. Now all panics are caught, logged
with stack traces, and the process continues running.

cb31782be4 refactor: split large files and clean up project structure 
- Rename experience/ to telemetry/ for clarity
- Split 15+ large Go files (800-2200 lines) into focused modules:
  kernel/engine.go, backtest/runner.go, market/data.go, store/position.go,
  api/handler_trader.go, trader/auto_trader_grid.go, and 9 exchange traders
- Split frontend monoliths: types.ts, api.ts, AITradersPage.tsx, BacktestPage.tsx
  into domain-specific modules with barrel re-exports
- Remove stale files: screenshots, .yml.old, pyproject.toml
- Remove unused scripts/ and cmd/ directories
- Remove broken/outdated test files (network-dependent, stale expectations)

093d2a329d feat(gate): complete Gate.io exchange integration with trader refactoring 
Gate.io Integration:
- Add Gate trader with full Trader interface implementation
- Add order_sync.go for background trade synchronization
- Fix quantity display (convert contracts to actual tokens via quanto_multiplier)
- Fix fill price return in OpenLong/OpenShort/CloseLong/CloseShort
- Add Gate-specific CoinAnk K-line data source support
- Add Gate to supported exchanges in frontend and backend
- Add Gate/KuCoin logo SVG icons

Trader Package Refactoring:
- Move exchange-specific code into subdirectories (binance/, bybit/, okx/, bitget/, hyperliquid/, aster/, lighter/, gate/)
- Create types/ package for shared types to avoid circular dependencies
- Move TraderTestSuite to trader/testutil package to avoid import cycles
- Update market.GetWithExchange to support exchange-specific data
