Subject: [PATCH 02/17] ui: replace gradient accent with muted dark buttons
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Drop the blue-to-purple gradient on primary buttons and sidebar indicator —
too "AI starter template". Buttons now use bg-tertiary + border with subtle
accent border on hover, matching the GitHub Dark aesthetic. Sidebar active
indicator back to solid accent.

Subject: [PATCH 03/17] fix: cancelOrder return type + parseOperationResult
 status mapping
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

cancelOrder returned boolean, causing parseOperationResult to reject all
cancel operations (typeof boolean !== 'object'). Changed to PlaceOrderResult
across IBroker interface and all 3 broker implementations.

parseOperationResult now derives status from orderState.status instead of
hardcoding 'submitted' — Filled/Cancelled/Inactive map correctly. Async
exchanges unaffected (they return Submitted → 'submitted' as before).

Also fixed modifyOrder parameter type: Order → Partial<Order> to match
actual usage, removing the unsafe cast in UTA dispatcher.

Subject: [PATCH 04/17] ui: add OpenAI backend card + tone down button styling

Add a third backend option "OpenAI" to the AI Provider page as a
simplified facade over Vercel AI SDK (provider=openai). Shows a
streamlined form with just model selector, API key, and base URL.
Auto-detects OpenAI config on page load. Full Vercel AI SDK form
remains for advanced users.

Also replace gradient buttons with muted dark style (bg-tertiary +
border) and change sidebar active indicator to solid accent.

Subject: [PATCH 05/17] =?UTF-8?q?refactor:=20eliminate=20Platform=20layer?=
 =?UTF-8?q?=20=E2=80=94=20one=20config=20=3D=20one=20UTA?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

Platform (IPlatform, CcxtPlatform, AlpacaPlatform) was a stateless factory
with zero business logic — just merged config fields and called `new Broker()`.

Now: accounts.json carries all fields (type, exchange, sandbox, credentials)
directly. `createBroker(config)` replaces the entire Platform layer.

- Merge platform + account schemas into discriminated union on `type`
- Delete CcxtPlatform.ts, AlpacaPlatform.ts, IPlatform interface
- Simplify main.ts init: single loop, no platformRegistry
- Simplify reconnect: no platform rebuild
- Remove platform CRUD routes, flatten UI to account-only
- Remove UTA.platformId (no longer needed)

Result: -431 lines, one config file, cleaner mental model.

Subject: [PATCH 06/17] fix: backend switch drops stale model config + improve
 Agent SDK error logging
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Backend switch only updated the `backend` field, leaving `provider`/`model`
from the previous backend (e.g. gpt-5.2-pro) — causing Agent SDK to crash
with an opaque "exit code 1". Unified all switch branches into a single

BrokerError.from() classifies raw SDK errors by message patterns into
typed error codes (NETWORK, AUTH, EXCHANGE, MARKET_CLOSED, CONFIG).

All broker query methods now wrap errors as BrokerError instead of
letting raw Error objects escape. UTA._callBroker() adds a safety net
for any remaining untyped errors.

Tool layer catches errors on query tools (getAccount, getPortfolio,
getOrders, getQuote, getMarketClock) and returns structured responses
with { error, code, transient, hint } so the AI can decide whether
to retry or report to the user.

Subject: [PATCH 08/17] test: fix E2E for sync-fill behavior + market hours
 skip
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

uta-real-broker: sync assertions now handle both synchronous fills
(status='filled' at push time, sync has nothing to do) and async
fills (status='submitted', sync confirms fill).

alpaca-paper: split into connectivity (any time) and trading (market
hours only) groups. Non-trading tests no longer fail when market is
closed — they skip gracefully instead of hitting 403.

Subject: [PATCH 09/17] refactor: split uta-real-broker e2e into uta-alpaca +
 uta-bybit

Clearer naming: broker-level tests (alpaca-paper, ccxt-bybit) vs
UTA-level tests (uta-alpaca, uta-bybit, uta-lifecycle).

Subject: [PATCH 10/17] refactor: use beforeEach skip for E2E preconditions

Replace per-test `if (!broker) return` / `if (!marketOpen) return` with
beforeEach(({ skip }) => ...) at describe level. Tests now show as
'skipped' (yellow) instead of 'passed' (green) when preconditions aren't met.

Added E2E README documenting conventions: file naming, precondition
pattern (beforeEach skip), market hours handling, setup.ts usage.

+# Trading E2E Tests
+
+End-to-end tests that run against real broker APIs (Alpaca paper, Bybit demo) and MockBroker.
+
+## Running
+
+```bash
+pnpm test:e2e
+```
+
+Tests run sequentially (`fileParallelism: false`) because broker APIs are shared resources.
+
+## File Naming
+
+| Pattern | Level | Example |
+|---------|-------|---------|
+| `{broker}.e2e.spec.ts` | Broker API | `alpaca-paper` — calls `broker.placeOrder()` directly |
+| `uta-{broker}.e2e.spec.ts` | UTA (Trading-as-Git) | `uta-alpaca` — uses `stagePlaceOrder → commit → push` |
+| `uta-lifecycle.e2e.spec.ts` | UTA + MockBroker | Pure in-memory, no external deps |
+
+## Precondition Pattern
+
+Use `beforeEach(({ skip }) => ...)` for preconditions — **never** `if (!x) return` inside test bodies.
+
+```typescript
+// ✅ Correct — shows as "skipped" in report
+beforeEach(({ skip }) => {
+  if (!broker) skip('no account configured')
+  if (!marketOpen) skip('market closed')
+})
+
+it('fetches account', async () => {
+  const account = await broker!.getAccount()  // broker guaranteed non-null
+})
+
+// ❌ Wrong — shows as "passed" even though nothing ran
+it('fetches account', async () => {
+  if (!broker) return  // silent pass, misleading
+})
+```
+
+For runtime data dependencies inside a test (e.g., contract search fails), use `skip()` from the test context:
+
+```typescript
+it('places order', async ({ skip }) => {
+  const matches = await broker!.searchContracts('ETH')
+  const perp = matches.find(...)
+  if (!perp) skip('ETH perp not found')
+})
+```
+
+## Market Hours
+
+- **Crypto (CCXT)**: 24/7, no market hours check needed
+- **Equities (Alpaca)**: Split into two `describe` groups:
+  - **Connectivity** — runs any time (getAccount, getPositions, searchContracts, getMarketClock)
+  - **Trading** — requires market open (getQuote, placeOrder, closePosition)
+
+Check `broker.getMarketClock().isOpen` in `beforeAll`, skip trading group via `beforeEach`.
+
+## Setup
+
+`setup.ts` provides a lazy singleton `getTestAccounts()` that:
+1. Reads `accounts.json`
+2. Filters for safe accounts only (Alpaca `paper: true`, CCXT `sandbox` or `demoTrading`)
+3. Skips accounts without API keys
+4. Calls `broker.init()` — if init fails, account is skipped with a warning
+
+Brokers are shared across test files via module-level caching.

Subject: [PATCH 12/17] refactor: align Position with IBKR, move crypto types
 to CCXT
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Position interface now matches IBKR's updatePortfolio() parameters —
removed leverage, margin, liquidationPrice (crypto-specific fields).

FundingRate, OrderBook, OrderBookLevel moved from shared types.ts
to ccxt-types.ts with a new CcxtPosition extension type.

CCXT tool descriptions now indicate "(CCXT/crypto accounts only)".
Added localSymbol semantics documentation to contract-ext.ts.

Subject: [PATCH 13/17] refactor: separate health recovery from data service
 pipeline
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Data queries (getAggregatedEquity, searchContracts, web routes) now
check UTA health before calling broker APIs:

- Offline UTA → skip + nudgeRecovery() (resets backoff timer for
  immediate retry) + return null/503
- Healthy UTA call fails → 503 (transient) or 500 (permanent)
- Write operations (push/reject) unchanged — failures must surface

Removed throttled console.warn from getAggregatedEquity — health
changes already pushed to frontend via SSE.

Added queryAccount() helper in trading routes for consistent
health-aware error handling with proper HTTP status codes.

Implements the full IBroker interface for IBKR via a RequestBridge layer
that bridges the callback-based @traderalice/ibkr SDK to Promise-based
IBroker methods. Three callback routing modes: reqId-based (contract
search, market data snapshots), orderId-based (order lifecycle), and
single-slot (account download for positions + account values).

New files: ibkr-types.ts, ibkr-contracts.ts, request-bridge.ts,
IbkrBroker.ts. Integrated into config schema, broker factory, and UI.

Subject: [PATCH 15/17] test: add IBKR E2E tests, refactor setup.ts safety
 mechanism

- Add `paper` field to IBKR config schema (default true)
- Refactor E2E setup.ts: replace hardcoded isSafe with unified isPaper()
  function that works across all broker types (ccxt sandbox/demo, alpaca
  paper, ibkr paper). Add TCP reachability check for local-process brokers.
- New ibkr-paper.e2e.spec.ts: broker-level tests (connectivity + trading)
- New uta-ibkr.e2e.spec.ts: UTA Trading-as-Git lifecycle test
- Update E2E README with IBKR documentation

+IBKR tests require TWS or IB Gateway running with paper trading enabled. Unlike REST-based brokers, IBKR connects via a local TCP socket — no API key is needed.

Subject: [PATCH 16/17] refactor: remove hardcoded credential assumptions, add
 IBKR to UI
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- main.ts: remove apiKey gate — let each broker's init() validate its
  own credentials (BrokerError CONFIG for missing keys)
- trading-config.ts: replace hardcoded apiKey/apiSecret masking with
  convention-based maskSecrets() (matches key|secret|password|token);
  remove credential check from test-connection endpoint
- TradingPage.tsx: create wizard supports IBKR (1-step, no credentials);
  edit panel credentials section keyed by broker type, not negation
- SDKSelector.tsx: add IBKR to platform type options

Subject: [PATCH 17/17] fix: clear handshake timeout on success to prevent
 uncaught TypeError

waitForHandshake() registered a setTimeout but never cleared it after
resolve. 10s later the timeout callback fired, hit this.conn (already
null after disconnect) and threw an uncaught TypeError that crashed
the process.
