 Pure UI architecture. No workspace dependency (parallel development).
 
-- [ ] Surface registration: `ctx.surfaces.register()` with label, icon, regions, activate/deactivate
-- [ ] Region management: `ctx.ui.replace()` / `ctx.ui.restore()` for CM6 state preservation
-- [ ] Mode selector in sidebar when ≥1 extension surface registered
-- [ ] `surface.activated` / `surface.deactivated` events
-- [ ] REPL console ([#70](https://git.gobha.me/xcaliber/chat-switchboard/issues/70)): fourth debug modal tab, AsyncFunction wrapper, injected globals, command history, tab-completion, admin-gated
+- [x] `data-surface-region` attributes on index.html containers (surface-header, surface-main, surface-footer, sidebar-content)
+- [x] `surfaces.js` — SurfaceRegistry: register, activate, deactivate, getCurrent, list
+- [x] `ctx.ui.replace()` / `ctx.ui.restore()` with DOM preservation (DocumentFragment-based)
+- [x] `ctx.surfaces.register()` API for extensions
+- [x] Mode selector component in sidebar (`#modeSelectorWrap`, auto-shown when ≥2 surfaces)
+- [x] Chat as default surface (implicit, always registered)
+- [x] `surface.activated` / `surface.deactivated` / `surface.registered` / `surface.unregistered` EventBus events
+- [x] REPL tab: AsyncFunction wrapper, global injection (API, Events, Extensions, Surfaces, DebugLog, Panels, UI, $, $$, sleep)
+- [x] REPL tab: pretty-print results (collapsible JSON, type-colored primitives, DOM element summaries)
+- [x] REPL tab: command history (sessionStorage, ↑/↓ navigation)
+- [x] REPL tab: tab-completion on object graphs, event labels, globals
+- [x] REPL tab: event label hints (Events.on/emit completion)
+- [x] REPL tab: admin gate (admin role OR ?debug=1 URL param)
+- [x] REPL tab: toolbar (clear, copy, help)
+- [x] CSS: mode selector + REPL styles
+- [x] Documentation in EXTENSIONS.md §6 updated with implementation details
+- [ ] Mobile: mode selector collapses to hamburger/bottom nav (deferred — functions via sidebar on mobile)
+- [ ] Integration with extension loader (surfaces from manifest — deferred to extension loader update)
