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).
Rank and percentile disagree by 30 points. rank 50% sits far below percentile 79%, both over the trailing year: one violent spike stretched the range, so this reading looks low against the high while being high against almost every other reading in it
39 of 39 with a reading on or before 2026-09-23. Each row is that name against its own history — core.metric_context(), one query for all of them — not a rank among them.
