From 2eda75f4e1e89a12402b02452e3c48bd7546499d Mon Sep 17 00:00:00 2001 From: Ame Date: Tue, 24 Mar 2026 09:13:17 +0800 Subject: [PATCH 1/9] =?UTF-8?q?feat:=20add=20UTA=20snapshot=20system=20?= =?UTF-8?q?=E2=80=94=20periodic=20+=20event-driven=20account=20state=20cap?= =?UTF-8?q?ture?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Snapshots capture full account state (equity, positions, orders, health) independently of trading operations. Triggered by cron schedule (every 15m), post-push/post-reject hooks, or manual call. Stored as chunked JSONL (50 per chunk) with an index file for efficient time-range queries. Includes write serialization to prevent concurrent append corruption, store caching per account, and 35 test cases covering builder, store, service, scheduler, and UTA hook integration.

1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Backend: two new endpoints — per-account snapshots and aggregated equity curve (minute-aligned, cross-account summation). SnapshotService exposed via EngineContext. Frontend: Recharts AreaChart with time range filters (1H–30D), per-account tooltip breakdown, and click-to-inspect snapshot detail panel showing positions and open orders at that point in time. Integrated into PortfolioPage between hero metrics and account strip.

This was a Python→Node adaptation bug: Python's recvMsg() catches socket.error inline and calls self.disconnect(), never propagating the error. Now socket errors call this.disconnect() directly, triggering wrapper.connectionClosed() which feeds into UTA health degradation and auto-recovery. Also fixed disconnect() to prevent double-calling connectionClosed() (once from disconnect, once from the close event).
