/**
 * `<gen type="running">` — a total that carries down a COLUMN.
 *
 * `accumulate=` on a `repeat` list keeps a total inside one record. This is the
 * other axis: row i's value is the accumulation of every row up to it. An
 * account balance, a meter reading, a cumulative count.
 *
 * The two share their arithmetic on purpose — see `accumulateColumn` — so the
 * scale rule, the handling of an empty cell and the exactness of a decimal sum
 * cannot drift apart between them.
 *
 * This is the one construct in TDC that is genuinely NOT computable from a row
 * index alone: row 900,000,000 is the sum of everything before it. That is not
 * an oversight in the streaming engines, it is what "running" means. So the
 * streaming builder refuses it by name and the router sends the config to the
 * in-memory engine, exactly as it does for every other whole-column construct.
