 ## Unreleased
 
+- **Breaking**: `html::edit` becomes `Document::edit`, in every binding —
+  java's `Html.edit(document, diff)` becomes `document.edit(diff)`, and so on.
+  `Text::set_content` is unchanged.
+
 - **Breaking**: `DecodePreference` becomes `DecodeOptions`, gains a `csv` field
   and is all `open` takes besides the file and logger. `CsvFile::from_file` and
   `::with_options` go — use `DecodeOptions::as(type)` / `::as_csv(options)`.

+`html::edit` goes. The op-log *semantics* stay exactly what they are today —
+this is the entry point moving to where v7.x can fill it in without breaking
+again. Named `edit` rather than `apply` to sit beside `is_editable`, and
+because JNI had already put it there: `jni_document.cpp` carried the comment
+*"odr::html::edit, but it belongs to Document"*.
+
+**`Text::set_content` stays.** An earlier draft of this plan removed it as the
+second road. That was wrong. The two are not one operation spelled twice: one
+edits a named element in process, the other replays a log a browser produced.
+`set_content` is mirrored in the java, python and objc bindings and exercised
+by the Swift suite, so removing it would take capability away and force a
+caller who wants to change one text run to assemble JSON. What was actually
+wrong here was the *filing* — an editing entry point in `namespace html`, whose
+only connection to html is that our JavaScript writes its input.
