//! §9 `update` authoring tests — the [`Update`] base-change ([`crate::change::field`]):
//! every [`FieldEdit`] applied and `updated` bumped, the whole-buffer `--edit`
//! replace (created preserved, updated restamped), the on=update blocker refusal,
//! the None-clears, the retitled finalize subject, and `narrated()`. Shares the
//! parent module's `write`/`TASK`/`RICH` fixtures via [`super`].
