A year is a 90-point range
Deep dive D7 (2026-09-21): 403 anchors from 2023 to 2025, each with a full year of outcomes, scored against the bands the memory served.
Coverage of the p10–p90 band: 76% at one month, 77% at three, 76% at six, 75% at one year, against a nominal 80% and 80 to 82% at one to ten sessions.
Median width: 23 points at one month, 39 at three, 57 at six, 90 at one year. A chart state says very little about where a stock is in a year, and the wall shows exactly how little.
The pool under-represents names that later left the tape: 0.07% of the liquid analog rows are censored against 4% of all memory rows. Every long-horizon band on this site carries that sentence.
Try it: reveal at 5 sessions, then at 1 year, on the same wall.
