/**
 * `${{Nmae}}` with no sequence of that name used to reach the OUTPUT verbatim —
 * the seven characters `${{Nmae}}` landed in the data. In CSV that is at least
 * visibly wrong; in Parquet it goes into a typed UTF8 column and reads like a
 * legitimate string, so nothing downstream can tell. A guide in this repo
 * referenced an undeclared `${{Client}}` and shipped 50 000 rows that way.
 *
 * Only checked in the OUTPUT BLOCK, where every sequence has been registered.
 * A `<data>` inside `<env>` is visited mid-walk, when later declarations do not
 * exist yet, and flagging there would invent errors for valid configs.
 *
 * Escape hatch for deliberately emitting `${{…}}` (generating a config, a
 * GitHub Actions file, a Handlebars template): give `<env>` a different
 * `inject` pattern. This check stands down whenever inject is not the default,
 * so that case is already covered.

 * The same check for a `<data>` written inside a `<case>`.

 * It could not be made where the tag is walked: a case body may name a column
 * declared BELOW it, and every declaration is known only once the walk is done.
 * So the node is put aside and answered here, exactly as an `if=` expression is
 * — and the diagnostics are spliced back where the tag stood, so a reader gets
 * them in the order the file reads.
