+# Phase 15: Command Center V1
+
+## Goal
+
+Make the Web UI default route a useful local-first operations screen instead of
+requiring users to know a raw Race Hub session key.
+
+## Completed Scope
+
+- Added `/` as the Command Center route.
+- Added a top-level Command nav item while preserving Race Hub, Live, and Data
+  Library routes.
+- Shows local season coverage, weekend coverage, local session counts, and live
+  availability.
+- Selects a focus weekend from local data using current, upcoming, then recent
+  weekend priority.
+- Provides quick actions into Live Timing, Race Hub for the default local
+  session, and Data Library.
+- Lists recent local sessions with direct Race Hub links.
+- Added unit coverage for schedule selection helpers and the Command Center
+  page.
+- Added Playwright E2E and production smoke coverage for `/`.
+- Added visual regression coverage for Command Center at desktop, tablet, and
+  mobile viewports.
+
+## Constraints
+
+- React continues to call only local-first Go APIs; no direct OpenF1 reads were
+  added.
+- Live state remains read-only status from the existing Web live endpoint.
+- The page stays dense and operational rather than becoming a marketing landing
+  page.
+
+## Verification
+
+```bash
+npm --prefix frontend test -- --run
+npm --prefix frontend run build
+npm run test:e2e
+npm run test:e2e:prod
+npm run test:visual
+npm run test:visual:prod
+```
