 ## Current Goal
 
-Continue the trading-module mainline in autonomous mode. `P0-2` implementation is in place, deployed, and locally validated; the current stop point is the only allowed external blocker: invalid OKX read-only credentials on the remote runtime.
+Continue the trading-module mainline in autonomous mode until `Real-time Assisted Trading V1` is complete. The next active stage is `P0-4` Decision Packet And Proactive Alerting.

-## Completed In Last Session
+## Completed In This Run
 
-- Implemented and deployed `P0-2` groundwork:
-  - `BrokerReadModelService`
-  - `/trading/broker-state`
-  - `RiskContext.broker_state`
-  - execution risk-context integration with broker read model
-  - workbench broker account / position / order / alert summary
-  - `run_until_blocked.py` plus tests
+- Completed `P0-2` Real Account And Order Read Sync acceptance:
+  - corrected the remote OKX read-only credential mapping
+  - verified `/trading/broker-state` returns `broker_state_ok`
+  - verified `/trading/market-state` carries `broker_state_ok`
+- Completed `P0-3` Runtime Scheduling And Supervision implementation:
+  - `TradingRuntimeScheduler`
+  - `TradingRuntimeSupervisor`
+  - runtime task state with last success, next run, blockers, degraded mode, and incidents
+  - `/trading/runtime-status`
+  - `/trading/runtime/run-once`
+  - `scripts/run_trading_runtime.py`
+  - workbench Runtime Supervisor panel
 - Local quality gates passed:
   - `npm run lint`
   - `npm run build`
   - `npm run visual:snapshots`
-- Updated `scripts/deploy_server.exp` to preserve the remote `.env` file during deploys.
 
 ## Current Working State
 
-- Remote `/trading/broker-state` exists and returns `200`.
-- Current remote broker-state summary:
-  - `status = broker_state_unavailable`
-  - `error = okx_read_http_401:50111:Invalid OK-ACCESS-KEY`
-- This means:
-  - the code path is live
-  - the API path is live
-  - deploy and migration completed
-  - the blocker is not an implementation gap
-  - the blocker is invalid remote OKX read-only credentials
-- Remote market truth can still degrade if the local proxy host `192.168.3.73:10808` is unavailable.
+- Autonomous execution protocol is anchored at:
+  - `docs/AI_ICT_全自动开发执行流程_v1.md`
+- Product roadmap is anchored at:
+  - `docs/AI_ICT_实盘辅助决策系统开发方案_v2.md`
+- Runtime market truth depends on the local LAN proxy remaining available at:
+  - `192.168.3.73:10808`
+- Real broker read sync depends on the remote OKX read-only credentials in:
+  - `/root/deploy/ai-ict/.env`
 
 ## Exact Next Step
 
-Wait for valid remote OKX read-only credentials, then continue:
+Proceed directly to:
 
-### `P0-2` final acceptance close
+### `P0-4` Decision Packet And Proactive Alerting
 
-Targets:
+Goals:
 
-- make `/trading/broker-state` return real account / positions / orders / fills
-- make `RiskGovernor` consume real broker state
-- make the workbench show real `open position / pending order`
