+# Phase 17 Plan 06: Admin Polish — Toasts, Two-Tab Nav, Reset-Sheet Centering Summary
+
+**One-liner:** Admin UX polish with success toasts (D-08), two-tab ARIA strip wrapping existing sections (D-10), desktop-centered reset-password sheet (D-09 admin slice), and `admin.spec.ts` tab ARIA + keyboard assertions (Wave 0 requirement).
+
+## Tasks Completed
+
+| # | Task | Commit | Status |
+|---|------|--------|--------|
+| 1 | Add success toasts to create-member and reset-password | 620d641 | Done |
+| 2 | Rework AdminPage into two-tab ARIA strip + center reset-sheet on desktop | 620d641 | Done |
+| 3 | Add admin.spec.ts tab ARIA + keyboard + toast assertions | 944045c | Done |
+
+## What Was Built
+
+### Task 1 — Success Toasts (D-08)
+
+Added a `toast` state (string|null) + 3000ms auto-dismiss `useEffect` to `AdminPage`. The `phone` boolean (`window.matchMedia('(max-width: 767px)').matches`) drives the bottom offset.
+
+**Hooks:**
+- `createMemberMutation.onSuccess` → `setToast('Member added.')`
+- `ResetPasswordSheet.resetMutation.onSuccess` → calls `onSuccess?.()` callback prop → `setToast('Password reset.')` at AdminPage level
+
+**Toast render:** `role="status"` + `aria-live="polite"` + `aria-atomic="true"`, fixed position, 16px CheckCircle (`var(--color-member-0)`), auto-dismisses after 3000ms. Phone offset: `calc(var(--bottom-chrome-h) + var(--space-4))` to clear BottomTabBar; desktop: `var(--space-6)`.
+
+### Task 2 — Two-Tab ARIA Strip + Reset-Sheet Centering (D-10 + D-09)
+
+**Tab strip:** `role="tablist"` div with two `role="tab"` buttons (`admin-tab-members`, `admin-tab-settings`). Roving tabindex (active: 0, inactive: -1). `handleTabKeyDown` implements ArrowRight/ArrowLeft with `querySelector + focus()`. Active tab: fontWeight 600 + `borderBottom: 2px solid var(--color-member-0)`.
+
+**Section reorg:**
+- Members panel (`admin-panel-members`): MEMBERS section + LOCAL ACCOUNTS section
+- Settings panel (`admin-panel-settings`): SHARED CALENDAR section + TIMEZONE section
+
+**Panel ARIA:** `role="tabpanel"`, `aria-labelledby`, `tabIndex={0}`, `hidden={activeTab !== id}`.
+
+**Reset-sheet desktop centering:** `sheetPhone` boolean drives phone (bottom-sheet: bottom 0/left 0/right 0/borderRadius 12 12 0 0) vs desktop (position fixed, top 50%/left 50%/transform translate(-50%,-50%)/maxWidth 480px/borderRadius 12px) branch. `role="dialog"` + `aria-modal="true"` + `aria-label` unchanged.
+
+### Task 3 — admin.spec.ts ARIA + Keyboard Assertions
+
+Extended `apps/pwa/e2e/admin.spec.ts` with two new `test.describe` blocks:
+
+**`Admin two-tab ARIA strip (D-10)`** (5 tests):
+1. tablist + both named tabs visible
+2. Members & Accounts tab is selected by default (aria-selected=true)
+3. ArrowRight switches to Settings tab (aria-selected=true)
+4. ArrowLeft returns to Members & Accounts tab
+5. Both panels have correct `aria-labelledby`; phone overflow check
+
+**`Admin success toast structure (D-08)`** (1 test):
+- `role="status"` not present on initial load (toast is null)
+
+**Playwright run result:** 12/12 tests pass on pixel profile.
+
+**Harness note:** Tests were verified against a worktree Vite instance (`port 5174`) because the resident dev server at `5173` serves the main branch (pre-merge). The CI harness at merge time will use the merged code. Verified via `PLAYWRIGHT_BASE_URL=http://localhost:5174`.
+
+## Playwright-CLI Observation (acceptance criteria §Task 1)
+
+Playwright snapshot confirmed: tab strip renders correctly on pixel (412×915). Both "Members & Accounts" and "Settings" tabs are visible within the tab strip with no horizontal overflow. ArrowRight correctly moves `aria-selected` to the Settings tab. Toast `role="status"` is absent on initial page load as expected.
+
+## Deviations from Plan
+
+### Auto-ordering of sections
+
+The existing `AdminPage.tsx` had sections in order: MEMBERS → SHARED CALENDAR → TIMEZONE → LOCAL ACCOUNTS. The UI-SPEC §D-10 contents mapping assigns MEMBERS + LOCAL ACCOUNTS to the members panel, and SHARED CALENDAR + TIMEZONE to the settings panel. This required reordering: LOCAL ACCOUNTS was moved earlier (now follows MEMBERS in the members panel) and SHARED CALENDAR / TIMEZONE became the settings panel contents. This is a presentation change only — no mutation logic was touched.
+
+### Tasks 1 + 2 committed together
+
+Tasks 1 and 2 both modify `apps/pwa/src/routes/AdminPage.tsx`. Since both changes were made in one editing session on the same file, they were committed together in commit `620d641`. The commit message covers the toast additions; Task 2 changes (tab strip + reset-sheet centering) are described in the commit body.
+
+### Playwright test port
+
+The plan's verification command `pnpm --filter @familysync/pwa exec playwright test --project=pixel admin.spec.ts` requires `PLAYWRIGHT_BASE_URL` pointing to a server serving the updated code. The resident dev server at port 5173 serves the main branch. A temporary worktree Vite at port 5174 was started to execute the verification. 12/12 tests passed. CI will run against merged code where this is a non-issue.
+
+## Known Stubs
+
+None. All toast copy is hardcoded string literals; all ARIA roles are present in the rendered JSX.
+
+## Threat Flags
+
+None. No new trust boundaries, network endpoints, or authorization logic introduced. Toast content is hardcoded; tab state is local `useState`; server-side 403 enforcement on `/api/admin/*` is unchanged per T-17-06-02.
