 # Changelog
 
+## [0.37.13] — 2026-03-22
+
+### Summary
+
+Scorched Earth III — third dead-code purge. 5 files deleted (−2,269 net lines).
+The massive `ui-primitives.js` (1,133 LOC) is gone; its few remaining consumers
+(`debug.js`, `switchboard-sdk.js`) received inlined replacements. Theme management
+migrated from the global `Theme` object to the Preact SDK's `createTheme` module.
+SDK slimmed by removing 6 dead factory wrappers.
+
+### Removed
+
+- `src/js/ui-primitives.js` (1,133 LOC) — `esc()`, `createComponentRegistry()`,
+  `componentMixin()`, `Providers`, `Roles`, `showConfirm()`, `showPrompt()`,
+  `openModal()`, `closeModal()`, `Theme`, render helpers. All consumers deleted
+  or inlined.
+- `src/js/code-editor.js` (362 LOC) — tabbed CodeMirror 6 editor, zero consumers
+- `src/js/file-tree.js` (290 LOC) — workspace file browser widget, zero consumers
+- `src/js/user-menu.js` (206 LOC) — vanilla flyout menu; all surfaces use
+  Preact `sw/shell/user-menu.js`
+- `src/js/app-state.js` (139 LOC) — global `window.App` state; Preact surfaces
+  use local state hooks; `debug.js` state snapshot already guards with `typeof`
+
+### Changed
+
+- `src/js/debug.js` — inlined `openModal()`, `closeModal()`, `showConfirm()`,
+  `_escHtml()` (~44 LOC) to replace dependency on deleted `ui-primitives.js`
+- `src/js/switchboard-sdk.js` — removed 6 dead factory wrappers (`sw.notes()`,
+  `sw.panels()`, `sw.fileTree()`, `sw.codeEditor()`, `sw.layout()`,
+  `sw.userMenu()` + `_hydrateUserMenu()`); replaced global `Theme` with
+  `import { createTheme } from './sw/sdk/theme.js'`; inlined `esc()` and
+  `openModal`/`closeModal` helpers; net −213 LOC
+- `server/pages/templates/base.html` — removed 5 script tags (`app-state.js`,
+  `ui-primitives.js`, `user-menu.js`, `file-tree.js`, `code-editor.js`);
+  consolidated removal comments
+- `src/sw.js` — removed 5 entries from `SHELL_FILES` cache manifest
+
+### Design Notes
+
+- **6 old JS files survive:** `sb.js` (debug modal onclick handlers),
+  `events.js` (extension bridge), `switchboard-sdk.js` (extension compatibility),
+  `debug.js` + `repl.js` (active tooling), `workflow-surfaces.js` (deferred to
+  Preact rewrite). Targeted for removal as extensions migrate.
+- **`user-menu.css` kept:** extension surface template still renders server-side
+  user-menu HTML; CSS provides styling for the placeholder.
+- **Cumulative scorched earth:** 49 files deleted, ~−17,710 lines across three
+  passes (v0.37.10, v0.37.12, v0.37.13).
