History
Gahow Wang 9287a92461 research: low_svr21 combination study (STOP); daily option-chain snapshots 
svr_combo (preregistered): blending low_svr21 into overnight_recovery_top10
lifts Sharpe 0.81 -> 0.87 at w=1/3 but deepens MaxDD by 6pp (G1, G3
fail); as a fourth sleeve it dilutes the overnight book (1.49 -> 1.42).

fetch_options collects S&P 500 option chains after each close from
Alpaca's free indicative feed (quotes, day volume, OCC open interest),
solves IVs, and writes per-name iv_atm30 / skew / call-put spread /
option-stock volume summaries to data/options/us/. Forward-only history
for options-implied factors. Run by the quant-trading-options timer at
16:25 New York, Mon-Fri; it skips once the next session has opened.
