Cumulative series compared

Every panel of the cumulative index on one chart: the same step lines the committed PNGs draw, from the same numbers. Pick series on the left; the defaults index each line to its value on the reference date and use a log axis, so equal slopes are equal growth rates whatever the units.

Y axis: Normalise: Reference From Colour by: Direction: include tentative entries († series)

Lines are read from each folder's cumulative-<slug>.json, written by the folder's figure.py beside its PNG and compared in CI; counts and events rise from zero, remaining falls toward zero, and a staircase is a standing record's own value (the tooltip says which direction is better). With up = progress, a series whose progress runs downward — problems still open, seconds to a target, an upper bound — is drawn as its reciprocal, the exact mirror on a log axis, and marked ⇅ in the list; as recorded shows the native value. A series with no value on the reference date is indexed to its first value instead and listed under the chart. A series marked † has entries its panel leaves out as unconfirmed (a pending prize submission); include tentative entries redraws it with them, dashed. Which entries count as confirmed is each folder's decision, stated on its page, and a contested or partial problem-list row carries no date, so no toggle can place it on the axis.
