 # Develop Changelog
 
+## 2026-06-12 — Chapter editor: optional visual (WYSIWYG) mode alongside Monaco
+
+### Added
+- The chapter editor now has an optional **Visual (WYSIWYG) mode** next to the existing Monaco HTML-source editor, ported from the Tiptap editor built in novela-ng and adapted to Novela's own markup conventions. A **Visual / HTML** toggle button in the toolbar switches between the two; Monaco remains the default and the backing source of truth.
+  - **Tiptap is bundled, not CDN-loaded.** A new `containers/novela/editor-src/` npm project bundles Tiptap + the custom extensions into a single committed file, `static/editor-bundle.js` (`window.NovelaVisual`), loaded by the editor page with a plain `<script>` tag — the runtime frontend stays build-less. Rebuild with `cd containers/novela/editor-src && npm install && npm run build`. `node_modules` is git-ignored; the bundle is committed.
+  - **Novela conventions modelled as a real ProseMirror schema** so they apply and round-trip as formatting instead of raw tags: subheading (`span.subheading`), chat (`span.chat`), author comment (`div.novela-comment`), indented paragraph (`<p style="padding-left: 40px;">`), and scene break (`<center><img src="…break.png" style="height:15px;"/></center>` — the original img `src` is preserved, so both DB `/static/break.png` and on-disk EPUB `../Images/break.png` breaks round-trip exactly). Standard bold/italic/underline/superscript/subscript, H2/H3 headings, and bullet/numbered lists are also available as visual-only toolbar buttons.
+  - **Detect & block (no silent data loss).** ProseMirror drops any markup its schema doesn't model, which would silently strip formatting from arbitrary EPUB/DB HTML. Switching into Visual mode is therefore gated by a round-trip safety check (`NovelaVisual.roundtripSafe`): the chapter is fed through the editor and the result is compared, canonicalised, against the original (ignoring insignificant formatting differences such as attribute order, whitespace, self-closing style, and `b`/`strong` & `i`/`em` equivalence). If anything — a tag, attribute, or text — would be altered or dropped, Visual mode is refused for that chapter and editing stays in HTML mode. In practice this means Visual mode is offered for clean, convention-conforming content (typically DB books) and declined for heterogeneous EPUB markup or whole-xhtml documents, so a book's existing formatting can never be quietly destroyed.
+  - The semantic toolbar buttons (Break, S, C, →|, [ ]) route to the corresponding Tiptap commands in Visual mode and to the existing Monaco text-wrapping in HTML mode. Visual edits participate in the existing per-chapter dirty-tracking, Save / Save-all, chapter switching, add/delete, and Find & Replace flows; the visual content is synced back into Monaco (the backing store) at every save/switch/replace boundary, and the safety gate is re-evaluated whenever a chapter is loaded. Ctrl/Cmd+S also saves while editing visually.
+  - Files: new `containers/novela/editor-src/{package.json,build.mjs,index.js,extensions.js,test.mjs,test-commands.mjs,test.html,.gitignore}`; new committed `static/editor-bundle.js`; `templates/editor.html` (bundle script, toggle button, visual-only toolbar group, `#visual-pane`); `static/editor.css` (visual pane, toolbar and convention styling); `static/editor.js` (pane abstraction, `toggleVisual`/`mountVisual`/`syncVisualToMonaco`/`refreshVisualAfterLoad`, boundary syncing, toolbar routing). No backend changes — chapter save is unchanged and does not sanitise, so the editor's clean output is stored as-is.
