+<objective>
+Remove copy-from-locale from admin `mltext` and `mlmarkdown` fields. Keep one locale selector per field, synchronized across ML controls, and nested `Record<string,string>` save bodies. Copy currently overwrites the active locale with the other locale's (often empty) string, so the editor appears to go blank.
+
+Purpose: Journal UAT — the operator does not want Copy, and the control is lossy.
+Output: SPA components and tests, forms.md sentence, rebuilt `modules/boardwalk/dist`, one code commit.

+
+Facts:
+
+- Both ML components have a visible locale `<select data-ml-locale>`, a second unlabeled `<select data-ml-copy-from>` (other locales), and a Copy button that runs `copyLocale()`: `values[active] = values[copyFrom] ?? ''`. On create, the other locale is `""`, so Copy blanks the field the operator is editing.
+- `otherLocales` and `copyFrom` exist only for that chrome. Locale broadcast (`broadcastMLLocale` / `ML_LOCALE_CHANGE`) stays.
+- `docs/backend/forms.md` "Markdown and multilingual fields" currently says "Copy-from-locale fills the active locale from another code already in the value." Delete that sentence. Historical Phase 14.2.1 PLAN/VERIFICATION files stay as-written.
+- Embedded SPA: after Vue edits, `npm --prefix admin run build` then commit `modules/boardwalk/dist`. `scripts/check-admin-dist.sh` is the drift gate.
+- Commit rules: one logical change, planning docs not in the code commit, no co-author trailers.

+
+In MLFields.test.ts, rewrite `edits the active locale and copies from another` to switch locale and type into the active field without `[data-ml-copy-from]` / `[data-ml-copy]`. In the existing "one locale selector" case, also assert those copy selectors and buttons are absent on both components.

+In docs/backend/forms.md, remove the Copy-from-locale sentence; leave the rest of the paragraph.

+# Quick 261006-s0v: Remove ML copy-from locale UI
+
+`mltext` and `mlmarkdown` now show one locale picker. The second unlabeled dropdown and Copy button are gone, so switching language cannot blank the field you are editing.
+
+## What was built
+
+**Task 1 (commit 2f03128)**
+- `MLTextField.vue` and `MLMarkdownField.vue`: dropped `copyFrom`, `otherLocales`, `copyLocale`, the copy-from select, and the Copy button. Locale broadcast and nested `Record<string,string>` values are unchanged.
+- `MLFields.test.ts`: asserts copy selectors/buttons are absent; editing Polish keeps English.
+- `docs/backend/forms.md`: removed the Copy-from-locale sentence.
+- `modules/boardwalk/dist` rebuilt (`index-CRrQr2H1.js`).
