Get mechanical return statistics over standard windows for an Indian stock. Accepts NSE symbol, ISIN, or BSE code. Returns period returns (1W/1M/3M/6M/1Y/YTD/max), CAGR, annualized volatility, max drawdown, and 52-week high/low — all computed from the split/bonus-adjusted close series. A null return is always explained by exactly one of two fields: `incomplete_windows` (not enough price history for that window yet) or `corporate_action_flagged_windows` (a rights issue/demerger/spin-off/merger/bare consolidation fell inside the window, so the window mixes a mechanical value transfer with ordinary price movement and is nulled rather than reported — see `corporate_action_caveat` when present). If the query only resolved via a rename/merger/demerger-successor alias, the envelope carries `resolved_via` naming which kind fired. Descriptive statistics only; no verdicts.
