description	Stabilize the Qianchuan live board trend route. Use when diagnosing or changing the opening trend chart, every-minute/5-minute/30-minute granularity, net deal amount trend, board-trend-collector.js, boardTrend, or boardTrendCollectStatus in the project workspace.

Qianchuan Five Minute Trend

Core Rule

Treat the Qianchuan live board trend chart as its own route. Do not infer this chart from visual snapshots, plan metrics, hourly details, or local cumulative totals when a board trend response is available.

Required Workflow

For any change involving the opening trend chart or boardTrendCollectStatus, read references/trend-workflow.md before editing code.

This route owns:

• state.boardTrend.points
• state.boardTrend.granularity
• state.boardTrendCollectStatus
• the dashboard opening trend chart when state.boardTrend.points exists

Project Files

• Collector logic: local-backend/executor/board-trend-collector.js
• CDP event support: local-backend/executor/cdp-client.js
• Routes and scheduler: local-backend/server.js
• Chart rendering: local-backend/public/preview.js
• Runtime state: local-backend/data/state.json

Validation

After edits, run:

node --check local-backend/executor/cdp-client.js
node --check local-backend/executor/board-trend-collector.js
node --check local-backend/server.js
node --check local-backend/public/preview.js

Then verify:

curl -s http://127.0.0.1:8788/api/board-trend/status
curl -s -X POST http://127.0.0.1:8788/api/board-trend/run -H 'content-type: application/json' -d '{"granularity":5}'

Expected behavior:

• state.boardTrend.points matches the Qianchuan live board trend API.
• The chart legend says 千川大屏趋势.
• Net deal amount comes from the board trend response, not a guessed local calculation.
• A timeout reloads the board page once, then marks the route skipped without blocking other skills.
