charset=UTF-8 Content-Transfer-Encoding: 8bit - auto_cycle.py: detect weekend/market session, build cycle_meta with day_of_week/is_weekend/market_note; IVGate skips iv_rank>=99 on weekends to avoid artificial weekend option premium cascade; inject portfolio context (open trades + price moves + concentration) before AI scoring; pass portfolio_context_block + run_id to both AI scorer and suggester - ai_analyzer.py: _build_temporal_news_block injects market session banner (WEEKEND warning, pre/after-market note, or open session label) so AI knows markets are closed and defers execution to Monday - iv_engine.py: add WHEAT/EUR/USD ticker aliases; skip saving IV snapshots on weekends to protect history; resolve aliases before slash-format conversion in _resolve_ticker - technical_indicators.py: fix pandas MultiIndex from yfinance>=0.2 (droplevel+squeeze); use period proportional to lookback instead of fixed period=1d - database.py: asset_class ticker-based fallback (_asset_class_from_ticker); one-time backfill migration for all NULL asset_class rows; ai_call_logs table + save/get helpers;
