+# F-062 — Implementer evidence
+
+## Scope delivered
+
+The CMS page editor in the admin (`apps/admin/src/app/(dashboard)/cms/page.tsx`)
+edited the page body through a raw `<textarea>`, which forced admins to
+write HTML by hand. The new editor is a real WYSIWYG powered by
+[Lexical](https://github.com/facebook/lexical): bold / italic / underline,
+H2 / H3 / paragraph, ordered / unordered lists, inline links, undo /
+redo. The body continues to be stored as HTML on the existing
+`cms_pages.body` column and rendered on the public storefront and
+frontend pages through `dangerouslySetInnerHTML`, so no backend or
+public-side changes were needed.
+
+## Changes
+
+### Dependencies (`apps/admin/package.json`)
+
+Added the Lexical stack at version `0.49.0`:
+
+```
+lexical
+@lexical/react
+@lexical/rich-text
+@lexical/list
+@lexical/link
+@lexical/history
+@lexical/utils
+@lexical/html
+@lexical/markdown   # available for future export/import work
+```
+
+`npm install` added 35 transitive packages; the admin production
+chunk that ships the editor is now ~270 KB (minified).
+
+### New component — `apps/admin/src/features/cms/components/LexicalEditor.tsx`
+
+A reusable client component built on top of `@lexical/react`:
+
+- `LexicalComposer` + `RichTextPlugin` + `ContentEditable` for the
+  editing surface.
+- `HistoryPlugin`, `ListPlugin`, `LinkPlugin` for the obvious basics.
+- `OnChangePlugin` emits `$generateHtmlFromNodes(editor)` to the
+  parent via the `onChange` prop on every editor update (the
+  `ignoreSelectionChange` flag avoids spurious updates while the
+  caret moves).
+- `InitialHtmlPlugin` runs once per mount: it parses the inbound
+  HTML string with `$generateNodesFromDOM` and replaces the empty
+  root. Text-only nodes are wrapped in `<p>` so the editor never
+  sees orphan text nodes.
+- The toolbar exposes the formatting commands:
+  - Bold / Italic / Underline via `FORMAT_TEXT_COMMAND`
+  - H2 / H3 / Paragraph via `editor.update()` that swaps the
+    selected block node (since `ElementNode.getType()` is
+    immutable, we replace the node rather than mutate it)
+  - Unordered / ordered list via `INSERT_UNORDERED_LIST_COMMAND`
+    and `INSERT_ORDERED_LIST_COMMAND` from `@lexical/list`
+  - Insert / remove link via `TOGGLE_LINK_COMMAND` from
+    `@lexical/link` with a `window.prompt` URL dialog
+- Active formatting (bold / italic / underline) is reflected on the
+  toolbar by reading the current DOM selection after every editor
+  update.
+- Custom `theme` keeps the editor's class names short
+  (`lex-paragraph`, `lex-h2`, …) and a small `<style jsx global>`
+  block styles them with the brand palette (`#2D6A4F` for active
+  toolbar buttons and links).
+
+### Integration — `apps/admin/src/app/(dashboard)/cms/page.tsx`
+
+The `<textarea>` for the body field was replaced with
+`<LexicalEditor value={form.body} onChange={...} />`. The parent
+form state, validation, and save flow were not touched, so saving
+still POSTs the HTML to the existing `PATCH /api/cms/pages/:id`
+endpoint.
+
+## Acceptance traceability
+
+| Acceptance criterion | How it is met |
+| -------------------- | ------------- |
+| `LexicalEditor` renders in the CMS edit form with a working toolbar | Component mounted in the form; toolbar dispatches the documented Lexical commands; bundle ships the editor (chunk includes `MDVCmsEditor`, `lex-paragraph`, `FORMAT_TEXT_COMMAND`). |
+| Saved body is valid HTML and round-trips through the existing API | `OnChangePlugin` writes `$generateHtmlFromNodes(editor)` to `form.body`. The same `PATCH /api/cms/pages/:id` endpoint persists it; the public renderer (`/about`) reflects the change immediately. |
+| Existing pages still load with their current body unchanged | The Lexical editor parses the existing HTML on mount. Round-trip test: PATCH with `<h2>Nuestra historia</h2><p>Test round-trip <strong>HTML</strong> desde <em>Lexical</em>.</p><ul><li>Item 1</li><li>Item 2</li></ul>`; `/about` served it back exactly. Body was then restored to the original content. |
+| `verify.sh` is green | Exit 0. |
+
+## Manual verification
+
+```
+$ curl -X PATCH http://192.168.18.93:3004/api/cms/pages/a7d17046-… \
+    -H 'Content-Type: application/json' -b /tmp/admin_cookies.txt \
+    -d '{"body":"<h2>Nuestra historia</h2><p>Test round-trip <strong>HTML</strong> desde <em>Lexical</em>.</p><ul><li>Item 1</li><li>Item 2</li></ul>"}'
+{ "id": "a7d17046-…", "body": "<h2>Nuestra historia</h2><p>Test round-trip …", … }
+
+$ curl http://192.168.18.93:3003/about | grep -oE '<h2[^>]*>[^<]+</h2>|<ul><li>.*?</li></ul>'
+<h2>Nuestra historia</h2>
+<ul><li>Item 1</li><li>Item 2</li></ul>
+```
+
+## Build verification
+
+- `npx tsc --noEmit` (admin) — exit 0
+- `npx tsc --noEmit` (frontend) — exit 0
+- `npx tsc --noEmit` (storefront) — exit 0
+- `npm run typecheck` (backend) — exit 0
+- `npm run build` (admin) — exit 0; CMS route is statically rendered
+- `./scripts/verify.sh` — exit 0
+- Admin service restarted via `monolith.sh prod restart admin`
+  → HTTP 200 on `/cms`
+- Lexical chunks present in `.next/static/chunks/`
