+# Phase 6 Plan 01: Sidebar layout — AdminSidebar + AppShell + move client list to /admin/clients Summary
+
+Replaced the top horizontal NavBar with a persistent left sidebar (AdminSidebar). Admin layout is now a flex-row AppShell. Client list moved from /admin to /admin/clients. /admin redirects to /admin/clients as temporary placeholder until dashboard is built in 06-02.

+| Task | Name | Commit | Files |
+|------|------|--------|-------|
+| 1 | Create AdminSidebar component | 2283740 | src/components/admin/AdminSidebar.tsx |
+| 2 | Update AdminLayout to AppShell | 29e0e88 | src/app/admin/layout.tsx |
+| 3 | Move client list to /admin/clients | 191b548 | src/app/admin/clients/page.tsx, src/app/admin/page.tsx |
+| 4 | Delete NavBar.tsx + verify build | 4d52d87 | src/components/admin/NavBar.tsx (deleted) |
+
+## What Was Built
+
+**AdminSidebar.tsx** — client component with:
+- 7 nav links: Dashboard (exact match), Clienti, Progetti, Offerte, Forecast, Catalogo, Impostazioni
+- Active route highlighting via `usePathname` with exact-match support for /admin
+- Logout button at bottom with `signOut({ callbackUrl: "/admin/login" })`
+- Brand green sidebar bg `#1A463C`, 224px fixed width
+
+**AppShell layout** — `layout.tsx` is now `flex min-h-screen`: sidebar (shrink-0, w-56) left + `<main className="flex-1">` right. Removed `max-w-5xl` container constraint.
+
+**Route migration** — `/admin/clients/page.tsx` is a direct copy of the old `/admin/page.tsx` with the archived toggle URL updated from `/admin?archived=1` to `/admin/clients?archived=1`. `/admin/page.tsx` now simply calls `redirect("/admin/clients")`.
+
+## Deviations from Plan
+
+None — plan executed exactly as written.
+
+## Verification
+
+- `npx tsc --noEmit`: PASSED — no errors
+- `npm run build`: PASSED — all 22 routes compile, /admin/clients appears as dynamic route
+- No NavBar references remain in codebase (`grep` found zero matches)
+- NavBar.tsx deleted from src/components/admin/
+
+## Self-Check: PASSED
+
+- [x] src/components/admin/AdminSidebar.tsx — created (2283740)
+- [x] src/app/admin/layout.tsx — updated (29e0e88)
+- [x] src/app/admin/clients/page.tsx — created (191b548)
+- [x] src/app/admin/page.tsx — redirect placeholder (191b548)
+- [x] src/components/admin/NavBar.tsx — deleted (4d52d87)
+- [x] npm run build passes
