/**
 * A share that asks for less than one whole row.
 *
 * `percent` is an exact quota over the rows that reach it, not a chance rolled
 * per row. Ten percent of a five-row subset asks for HALF a record, and half a
 * record cannot be emitted — so the branch produces one or none, and the seed
 * alone decides which. The engine rounds and says nothing, which is how a column
 * that came out empty reads as a config that was never written rather than one
 * that rounded away.
 *
 * It is a warning, not an error. The config runs, the totals still sum to
 * `count`, and nothing is lost; what does not happen is what the author wrote.
 *
 * ── Why the denominator is knowable ──────────────────────────────────────────
 * The obstacle sounds like "the validator cannot know how many rows reach the
 * branch", and for the shapes people actually write it can:
 *
 *   - a `<mix>` or a `<gen percent=>` at the top of `<env>` — the denominator is
 *     `count`;
 *   - either of those with `parent="Seq.Value"` — `count` x that value's share;
 *   - a `<mix>` inside `<case is="X">` of `<switch on="S">` — `count` x the share
 *     `X` takes of `S`.
 *
 * A share is only known when the subject is a plain `text` generator writing its
 * own `percent`. Anywhere else — a file, a pack, an expression — this stays
 * SILENT. A check that guessed the denominator would fire on working configs and
 * be turned off, which is worse than the silence it replaces.
