 # Changelog
 
+## [0.37.12] — 2026-03-22
+
+### Summary
+
+Scorched Earth II — second dead-code purge. 23 files deleted (~2,600 lines).
+All six core surfaces are confirmed Preact-only; old vanilla JS, CSS, and
+admin templates removed. Service worker cache manifest overhauled.
+
+### Removed
+
+- `src/js/ui-format.js` — old markdown renderer (replaced by `sw/components/chat-pane/markdown.js`)
+- `src/js/virtual-scroll.js` — only consumer was deleted `chat.js`
+- `src/js/model-selector.js` — Preact ChatPane has its own `ModelSelector`
+- `src/js/drag-resize.js` — only consumer was deleted `PaneContainer`
+- `src/js/pages-splash.js` — login is Preact since v0.37.5
+- `src/js/task-sidebar.js` — no template loads this
+- `src/js/workflow-api.js` — new SDK has `sw.api.workflows.*`
+- `src/js/workflow-queue.js` — references deleted `App.chats`
+- `src/js/workflow-monitor.js` — ES module export, never imported
+- `src/css/splash.css` — replaced by `sw-login.css`
+- `src/css/styles.css` — 13-line decomposition comment from v0.22.9
+- `src/css/persona-kb.css` — old admin/settings UI
+- `src/css/notification-prefs.css` — old settings UI
+- `src/css/memory.css` — old admin/settings UI
+- `src/css/channel-models.css` — old chat autocomplete
+- `server/pages/templates/admin/` — 8 dead templates (overview, users,
+  models, providers, settings, teams, roles, routing); admin is Preact
+  since v0.37.6
+
+### Changed
+
+- `server/pages/templates/base.html` — removed 7 script/link tags:
+  `splash.css`, `marked.min.js`, `purify.min.js`, `ui-format.js`,
+  `virtual-scroll.js`, `model-selector.js`, `drag-resize.js`.
+  `marked`/`purify` now loaded only by surfaces that need them (chat, notes).
+- `src/sw.js` — replaced entire `SHELL_FILES` array; removed 17 stale
+  entries referencing files deleted in v0.37.10, added all `sw-*.css` files
+- `server/pages/pages.go` — removed `templates/admin/*.html` from
+  `//go:embed` directive and `ParseFS` call
+
+### Design Notes
+
+- **11 old JS files survive:** `sb.js`, `app-state.js`, `events.js`,
+  `ui-primitives.js`, `user-menu.js`, `file-tree.js`, `code-editor.js`,
+  `switchboard-sdk.js`, `debug.js`, `repl.js`, `workflow-surfaces.js`.
+  These provide globals consumed by extension surfaces (`Events.on()`,
+  `Theme.resolved()`, `sw.fileTree()`) and the debug modal (`sb.call()`).
+  Targeted for removal when extensions migrate to Preact SDK.
+- **`workflow-surfaces.js` deferred:** still loaded by `workflow.html`
+  standalone page; removed when workflow surfaces rebuilt (v0.37.13).
