Analyze

Analyze is the research diagnostics boundary. Use it to understand factors, returns, attribution, robustness, and time-series behavior after data and signals have been produced. Strategy execution and portfolio construction live in skills.backtest.

Phase 03 adds a deterministic AnalyzeFacade for factor-mining preflight, evaluation, and explicit pool comparison. The facade is read-only (no implicit I/O), fails fast on hard preflight/alignment/causality failures before return evaluation, and returns analyze-native structured results. Formal portfolio returns and costs always call skills.backtest.VectorBacktester.

skills.analyze must not import skills.factor_mining, strategies, store global paths, report rendering, controller/role/workflow code, or LLM SDKs.
