AWS S3 Configuration for Public Blockchain Data Access (UC-101)

Setting up AWS credentials to enable secure access to public blockchain data stored in S3, allowing integration with ArcticDB for time-series storage Triggers: aws, s3, credentials

Billion Row Challenge - Large Scale Data Performance (UC-102)

Demonstrates ArcticDB's ability to handle massive datasets (1 billion rows of temperature data) with efficient aggregation, serving as a performance b Triggers: billion rows, large scale, performance

Batch DataFrame Concatenation with Lazy Loading (UC-103)

Demonstrates efficient concatenation of multiple DataFrames stored in ArcticDB using lazy loading to minimize memory consumption during batch operatio Triggers: concat, batch, lazy

For all 17 use cases, see references/USE_CASES.md.

Execute trigger: When user intent matches intent_router.uc_entries[].positive_terms AND user uses action verb (run/execute/跑/执行/backtest/fetch/collect)

What I'll Ask You

• Target market: A-share (default), HK, or crypto? (US stocks in ZVT are half-baked — stockus_nasdaq_AAPL exists but coverage is thin)
• Data source / provider: eastmoney (free, no account), joinquant (account+paid), baostock (free, good history), akshare, or qmt (broker)?
• Strategy type: MACD golden-cross, MA crossover, volume breakout, fundamental screen, or custom factor?
• Time range: start_timestamp and end_timestamp for backtest period
• Target entity IDs: specific stocks (stock_sh_600000) or index components (SZ1000)?

Semantic Locks (Fatal)

| ID | Rule | On Violation | |---|---|---| | SL-01 | Execute sell orders before buy orders in every trading cycle | halt | | SL-02 | Trading signals MUST use next-bar execution (no look-ahead) | halt | | SL-03 | Entity IDs MUST follow format entity_type_exchange_code | halt | | SL-04 | DataFrame index MUST be MultiIndex (entity_id, timestamp) | halt | | SL-05 | TradingSignal MUST have EXACTLY ONE of: position_pct, order_money, order_amount | halt | | SL-06 | filter_result column semantics: True=BUY, False=SELL, None/NaN=NO ACTION | halt | | SL-07 | Transformer MUST run BEFORE Accumulator in factor pipeline | halt | | SL-08 | MACD parameters locked: fast=12, slow=26, signal=9 | halt |
