realized_vol_21d
Annualised stdev of the trailing 21 session returns. COMPUTED BACKWARD, unlike UW's /volatility/realized which computes it FORWARD over ~20 sessions and is therefore not knowable on the date it is stamped with (DESIGN.md:139, the highest-priority provenance hazard in the document).
