 # Changelog
 
+## [0.31.0] — 2026-03-18
+
+### Summary
+
+Editor package: the code editor surface is now an installable `.pkg`
+file (type `full`, tier `browser`). Zero platform special-casing —
+validates the entire v0.28.7–v0.30.2 extension stack. The editor
+package lives in `packages/editor/` and is installed via admin UI
+upload. Core editor surface, template, CSS, JS, and data loader removed.
+
+### New
+
+- **Editor `.pkg`** — `packages/editor/` contains `manifest.json`,
+  `js/main.js`, and `css/main.css`. Type `full`, tier `browser`.
+  JS-only rendering replaces server-rendered Go template partials.
+  Dynamic script loading for CodeMirror bundle and ChatPane.
+  Route: `/s/editor?ws=<id>`.
+- **Editor settings** — manifest declares `font_size`, `tab_size`,
+  `word_wrap` settings configurable via admin packages UI.
+- **UI state persistence** — open tabs, active tab stored in
+  localStorage per user per workspace (debounced 2s save).
+- **E2E tests** — `crud/editor-package.js` — install, type/tier
+  verification, settings CRUD, export/import round-trip, core
+  removal verification.
+
+### Removed
+
+- `surface-editor` Go template (`server/pages/templates/surfaces/editor.html`)
+- `editor-surface.js` and `editor-surface.css` (replaced by package assets)
+- `EditorPageData` struct and `editorLoader` function
+- Hardcoded `/editor` sidebar link (now rendered by extension nav loop)
+- `/editor` nginx location rule (served via `/s/editor`)
+- Editor entry from `registerCoreSurfaces()` and `extensionNavItems()` skip
+
+### Changed
+
+- `SeedSurfaces()` now cleans up the old editor core surface row to
+  prevent broken nav links before the package is installed.
+
