fix(notifications): make Materializer.Start race-free single-shot

The previous `if m.unsub != nil` check-and-set was unsynchronized, so concurrent
Start calls could double-subscribe and leak an unsubscribe handle. Use a
sync.Once (mirroring stopOnce) so only the first call subscribes.

+# Notifications & Push — Test Checklist
+
+A repeatable regression pass for the core notifications + push subsystems. Organized by layer: automated (fast, run anytime), server pipeline (API, no browser), real browser (human-in-the-loop), and not-yet-testable (future work). Run the automated layer on every change; run the browser layer before shipping a user-facing change.
+
+Specs/plans this exercises live under `docs/superpowers/specs|plans/2026-06-10-core-notifications-*` and `*-push-*`.
+
+---
+
+## 1. Automated tests (fast, no live instance)
+
+Run from the repo root. `export GOWORK=off` first (or run inside the worktree).
+
+```bash
+# Go — materializer, matchers, worker state machine, request events, presence, handlers, tasks
+GOWORK=off go test ./internal/notifications/ ./internal/push/ ./internal/presence/ \
+  ./internal/requests/ ./internal/api/handlers/ ./internal/taskmanager/tasks/
+
+# Web — bell, inbox, settings, admin page, usePushDevice, SW logic
+cd web && pnpm exec vitest run
+```
+
+Expected: all green. The Go suites cover the outcome state machine (sent/skipped/failed-with-backoff/dead + dead-token prune), child-suppression SQL, the `notifications.send` plugin contract, request lifecycle publishing, and presence refcounting. The web suites cover the UI and the `usePushDevice` lifecycle/race-guard.
+
+What this does NOT cover: real WebSocket delivery, real push banners, real migrations against production-shaped data. Use layers 2–3 for those.
+
+---
+
+## 2. Server pipeline (API — proves source → materializer → enqueuer → worker, no browser)
+
+Needs an admin API key and the instance reachable (on silo-new the API is `http://localhost:8090`; create a temp key, delete it after — see the snippet at the bottom). Observe results in the `notifications` and `push_deliveries` tables.
+
+For each notification **source**, trigger it and confirm a row lands (and, if push is configured + a device registered, a `push_deliveries` row):
+
+- [ ] **Announcement** — `POST /api/v1/admin/announcements {title, body, audience:{all:true}}` → confirm a `notifications` row (category `announcement`) for each targeted user. ⚠️ `audience:{all:true}` fans out to **every** user's inbox — use `{user_ids:[<your id>]}` when testing on a live instance.
+- [ ] **Request lifecycle** — submit a media request, then `POST /api/v1/requests/{id}/approve` (admin) → confirm a `request.approved` notification for the requester. Decline/complete/fail similarly produce `request.declined` / `request.completed` / `request.failed`.
+- [ ] **System** — admin user-update that changes a password → confirm a `system.password_changed` notification for that user.
+- [ ] **Content** — add an item to a profile's watchlist/favorites, then add/scan a matching library item → confirm a `content.added` notification for that profile (respects the 48h recency gate + per-day burst dedup).
+- [ ] **Admin alert** — force a failed job/scan → confirm an `admin`-category notification fans out to admin users only (throttled 1/hour per source).
+- [ ] **Digest** — opt a user into `content_digest`, then run the `notifications_digest` task (or wait for 08:00) → one digest notification if there were additions.
+- [ ] **Push test** — `POST /api/v1/admin/push/test` → 202; a `system.test_push` notification + a `push_deliveries` row per the caller's registered push devices; the worker transitions it within ~30–45s (grace + tick). With a real subscription it sends; with a bogus one it fails-with-backoff (still proves the worker path).
+
+Push config endpoints to verify:
+- [ ] `GET /api/v1/admin/push/status` → `{apns,fcm,webpush}` booleans (flip after saving creds).
+- [ ] `POST /api/v1/admin/push/generate-vapid-keys` → `{vapid_public, vapid_private}` (admin only).
+- [ ] `GET /api/v1/notifications/push/webpush-key` → the configured public key (empty when unconfigured).
+- [ ] `PUT /api/v1/notifications/push/device {transport:"webpush", token:<subscription JSON>}` with `X-Profile-Id` → 204 (400 without the profile header — the route is profile-gated).
+- [ ] `GET /api/v1/notifications/push/devices` → lists the user's push devices; `PUT .../devices/{id} {enabled}` toggles.
+
+---
+
+## 3. Real browser (the only way to validate the UI + actual push banner)
+
+Open the web app over a secure context (`localhost` or HTTPS — service workers require it). On silo-new that's `http://localhost:8090` (tunnel if remote).
+
+In-app notifications:
+- [ ] **Bell + badge** — top of the app; unread count badge.
+- [ ] **Dropdown** — latest notifications, "Mark all read", deep links.
+- [ ] **Inbox page** (`/notifications`) — category tabs, dismiss, mark-on-view, "Load more".
+- [ ] **Live toast** — with the app open, trigger a notification (announcement to yourself, or the push-test) → a toast appears in real time (via the WebSocket), unless that category is muted.
+- [ ] **Preferences** — Settings → Notifications → per-category mute toggles persist; "Daily digest" defaults off; the admin category shows only for admins.
+
+Push (the headline manual test):
+- [ ] **Admin config** — Admin → Settings → Push Notifications → "Generate keys", save the VAPID public/private + a `mailto:` subject → the Web Push badge flips to "Ready".
+- [ ] **Enable on this device** — Settings → Notifications → "Push on this device" → grant the browser permission prompt → a device row appears in the list.
+- [ ] **Background banner** — **close the app tab**, then `POST /admin/push/test` (or trigger any notification) → within ~30–45s an OS notification banner appears.
+- [ ] **Click-through** — click the banner → the app opens/focuses and navigates to the notification's deep link.
+- [ ] **Presence gating** — with the app tab open and focused, the same notification should NOT push a redundant banner (you saw it in-app); after closing the tab for >30s it does.
+- [ ] **Per-device toggle / revoke** — disable the device in the list → no more banners; re-enable restores.
+
+---
+
+## 4. Not yet testable (tracked future work)
+
+- **APNs (Apple) / FCM (Android)** — no mobile clients exist to register tokens, so these transports are only unit-tested (pure result-mappers). End-to-end needs silo-apple / silo-android (Phase 3 mobile).
+- **Plugin `notifications.send`** — the ebook/audiobook request plugins don't publish it yet. Until those one-line `PublishEvent("notifications.send", …)` calls are added, plugin-sourced notifications can't be exercised end to end (the contract itself is unit-tested).
+- **iOS Safari web push** — only works for an installed PWA, not a normal tab; the client degrades to an "unsupported" state otherwise.
+
+---
+
+## Appendix — temp admin key on silo-new (create, use, delete)
+
+```bash
+# create
+KEY="sa_$(openssl rand -hex 32)"
+docker exec silo-server-postgres-1 psql -U silo -d silo -tAc \
+  "INSERT INTO api_keys (user_id,label,api_key) VALUES (1,'manual-test','$KEY');"
+echo "$KEY"   # use as: Authorization: Bearer $KEY against http://localhost:8090/api/v1/...
+
+# observe
+docker exec silo-server-postgres-1 psql -U silo -d silo -tAc \
+  "SELECT id,category,type,title FROM notifications ORDER BY id DESC LIMIT 10;"
+docker exec silo-server-postgres-1 psql -U silo -d silo -tAc \
+  "SELECT status,transport,attempts,left(last_error,40) FROM push_deliveries ORDER BY id DESC LIMIT 10;"
+
+# clean up (delete the key + any test artifacts you created)
+docker exec silo-server-postgres-1 psql -U silo -d silo -tAc \
+  "DELETE FROM api_keys WHERE label='manual-test';"
+```
+
+Always remove test notifications/devices you create on a real user's account; `push_deliveries` cascades when its `notifications` row is deleted.

+# Core Notifications — Web UI Implementation Plan (Phase 2 of 3)
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Notifications UI in the silo-server web app: unread badge (sidebar + mobile header bell with dropdown), live toasts from the events WebSocket, an inbox page, per-category preference toggles in settings, and an admin announcements page.
+
+**Architecture:** A `notifications` query-hook module talks to the Phase-1 REST API; one live-wiring hook subscribes to the `notifications` WS channel via the existing `RealtimeEventsProvider` ref-counted `useEventChannel`, firing sonner toasts and patching React Query caches. UI components consume only the hooks. Desktop surface is an `AppSidebar` item with badge (no desktop top bar exists); mobile surface is a bell + popover in the `Layout` header.
+
+**Tech Stack:** React 19, React Router v7, TanStack Query, sonner, lucide-react, shadcn/ui primitives (Popover, Switch, Dialog), Vitest + RTL.
+
+**Spec:** `docs/superpowers/specs/2026-06-10-core-notifications-design.md` (Web UI section). Server API shipped in Phase 1.
+
+Commands assume the repository root is the cwd; web commands run in `web/`. `pnpm` is the package manager.
+
+---
+
+## Server API contract (frozen, Phase 1)
+
+The `api()` client prefixes `/api/v1` and adds auth + `X-Profile-Id` headers automatically.
+
+```

+GET    /notifications/unread-count                        → {"count": number}
+POST   /notifications/read         {"ids":[...]} | {"all":true}  → 204
+POST   /notifications/{id}/dismiss                        → 204 | 404
+GET    /notifications/preferences                         → {"preferences":[{"category","enabled"}]}

+DELETE /admin/announcements/{id}                          → 204 | 404
+```
+
+Notification JSON: `{id, user_id, profile_id?, category, type, title, body, link?, item_id?, created_at, read_at?, expires_at?}`. Categories: `request | content | announcement | system | admin`; preference categories additionally `content_digest` (never a notification category). WS: channel `"notifications"`, event `"notification.created"`, `data` = the Notification; subscribe snapshot `data` = `{"unread_count": number}`.

+### Task 2: Query keys and hooks
+
+**Files:**
+- Modify: `web/src/hooks/queries/keys.ts`
+- Create: `web/src/hooks/queries/notifications.ts`
+
+- [ ] **Step 1: Keys** — follow the existing factory style in keys.ts:
+
+```typescript
+export const notificationKeys = {
+  all: ["notifications"] as const,
+  list: (filters: { unread?: boolean; category?: string }) =>
+    [...notificationKeys.all, "list", filters] as const,
+  unreadCount: () => [...notificationKeys.all, "unread-count"] as const,
+  preferences: () => [...notificationKeys.all, "preferences"] as const,
+  announcements: () => ["admin", "announcements"] as const,
+};
+```
+
+- [ ] **Step 2: Hooks** — `web/src/hooks/queries/notifications.ts`. Mirror the conventions in `web/src/hooks/queries/admin/users.ts` (api client import path, toast usage, invalidation):
+
+```typescript

+
+export function useDismissNotification() {

+    onError: (err) => {
+      toast.error(err instanceof Error ? err.message : "Failed to delete");
+    },
+  });
+}
+```
+
+Check `api()`'s actual error behavior (does it throw on non-2xx with a message? read `web/src/api/client.ts:343-380`) and the import alias style (`@/` vs relative — match the queries directory's existing imports).

+
+**Files:**
+- Create: `web/src/hooks/useNotificationsLive.ts`
+- Test: `web/src/hooks/useNotificationsLive.test.ts`
+
+- [ ] **Step 1: Write the failing test**
+
+Mock `useEventChannel` (from `@/components/realtimeEventsContext`) to capture handlers, mock `sonner`'s toast, wrap in a QueryClientProvider. Follow the mocking style of `web/src/components/RealtimeEventsProvider.test.tsx` (vi.mock + vi.hoisted).

+- [ ] **Step 2: Run to verify failure**
+
+```bash

+
+Expected: FAIL — module `./useNotificationsLive` not found.

+export function useNotificationsLive() {
+  const queryClient = useQueryClient();
+  const { profile } = useAuth();

+      if (n.profile_id && n.profile_id !== profileId) return;
+      if (isChild && CHILD_HIDDEN_CATEGORIES.has(n.category)) return;
+
+      queryClient.setQueryData<{ count: number }>(notificationKeys.unreadCount(), (prev) => ({
+        count: (prev?.count ?? 0) + 1,
+      }));
+      void queryClient.invalidateQueries({
+        queryKey: [...notificationKeys.all, "list"],

+  );
+
+  useEventChannel("notifications", { onEvent, onSnapshot });
+}
+```
+
+NOTE on handler identity: `useEventChannel`'s effect re-subscribes when the handlers object changes — pass a stable object. Check how existing consumers handle this (grep `useEventChannel(` usages); if they memoize the handlers object, do the same: `useMemo(() => ({ onEvent, onSnapshot }), [onEvent, onSnapshot])`.
+
+The toast call shape (`toast(title, { description })`) must match the test's `expect.anything()` second arg. If `useAuth` returns a different profile field shape, adapt (read `useAuth.tsx`).

+### Task 4: NotificationBell component + Layout mount
+
+**Files:**
+- Create: `web/src/components/NotificationBell.tsx`
+- Test: `web/src/components/NotificationBell.test.tsx`
+- Modify: `web/src/components/Layout.tsx` (mobile header actions ~lines 151-168; also mount `useNotificationsLive()` once in the Layout component body)
+
+- [ ] **Step 1: Failing test**
+
+```typescript
+// Mocks: @/hooks/queries/notifications (useUnreadCount → 3, useNotificationsList → two items,
+// useMarkRead → mutate spy), react-router (MemoryRouter wrapper).
+// Asserts: badge renders "3"; opening the popover (click bell button, role="button" name /notifications/i)
+// shows both item titles; "Mark all read" calls markRead with {all:true};
+// item with link renders an anchor/Link to that link.
+```
+
+Write it concretely following an existing component test's structure (see `web/src/components/AppSidebar.test.tsx` for provider wrapping conventions). Badge cap: 4+ digits render "99+" when count > 99 — include one assertion with count 120.
+
+- [ ] **Step 2: Implement NotificationBell**
+
+```tsx
+import { Bell } from "lucide-react";
+import { Link } from "react-router";
+
+import { Badge } from "@/components/ui/badge";
+import { Button } from "@/components/ui/button";

+  const list = useNotificationsList({});
+  const markRead = useMarkRead();
+  const items = (list.data?.pages ?? []).flatMap((p) => p.items ?? []).slice(0, 10);
+
+  return (
+    <Popover>

+          )}
+        </Button>

+            Mark all read
+          </Button>
+        </div>
+        <ul className="max-h-96 list-none overflow-y-auto">
+          {items.length === 0 && (

+              You're all caught up
+            </li>
+          )}
+          {items.map((n) => (
+            <li key={n.id} className={n.read_at ? "opacity-60" : ""}>
+              <Link to={n.link ?? "/notifications"} className="hover:bg-accent block px-3 py-2">
+                <div className="text-sm font-medium">{n.title}</div>
+                {n.body && <div className="text-muted-foreground truncate text-xs">{n.body}</div>}

+          </Link>
+        </div>
+      </PopoverContent>
+    </Popover>
+  );
+}
+```
+
+Verify the ui primitives exist with these export names (`badge.tsx`, `button.tsx`, `popover.tsx` under `components/ui/`); adjust imports/props to the actual variants. Match `react-router` import name used elsewhere (the repo uses `react-router` v7 — check whether components import `Link` from `react-router` or `react-router-dom`).
+
+Dropdown-open toast suppression (spec requirement): export a tiny module-level flag from NotificationBell —
+
+```tsx
+let bellOpenFlag = false;
+export function isNotificationDropdownOpen() {
+  return bellOpenFlag;
+}
+// in the component: <Popover onOpenChange={(open) => { bellOpenFlag = open; }}>
+```
+
+and in `useNotificationsLive`'s onEvent, before toasting: `if (isNotificationDropdownOpen()) return;` (cache updates still run — only the toast is suppressed; the open dropdown shows the new item via the list invalidation). Add one live-hook test: set the flag via a popover-open simulation or export a test-only setter, assert no toast while open.
+
+- [ ] **Step 3: Mount in Layout**
+
+In `Layout.tsx`: call `useNotificationsLive()` at the top of the component (single mount point for the live hook), and render `<NotificationBell />` in the mobile header's right-side action cluster (next to the search icon button).
+
+- [ ] **Step 4: Tests green, typecheck, commit**
+
+```bash
+cd web && pnpm exec vitest run src/components/NotificationBell.test.tsx 2>&1 | tail -5 && pnpm exec tsc -b --noEmit 2>&1 | head -3
+git add src/components/NotificationBell.* src/components/Layout.tsx src/hooks/

+### Task 5: Sidebar nav item with badge (desktop)
+
+**Files:**
+- Modify: `web/src/components/AppSidebar.tsx` (nav list — insert after the History item, ~line 645)
+- Test: extend `web/src/components/AppSidebar.test.tsx`
+
+- [ ] **Step 1: Add the nav item**
+
+Follow the exact ViewTransitionLink pattern of the History item (active indicator span, icon sizing, `SidebarLabel`):
+
+```tsx
+<li>
+  <ViewTransitionLink
+    to="/notifications"
+    onClick={onNavigate}
+    className={navLinkClass("/notifications")}
+    aria-current={isActive("/notifications") ? "page" : undefined}
+  >
+    {isActive("/notifications") && (
+      <span
+        className="absolute top-1/2 left-0 h-[18px] w-[3px] -translate-y-1/2 rounded-r-sm"
+        style={{ background: "var(--primary)" }}
+      />
+    )}
+    <Bell className="h-[18px] w-[18px] shrink-0" />
+    {unreadCount > 0 && (
+      <span className="bg-primary text-primary-foreground absolute top-1 left-6 flex h-4 min-w-4 items-center justify-center rounded-full px-1 text-[10px]">
+        {unreadCount > 99 ? "99+" : unreadCount}
+      </span>
+    )}
+    <SidebarLabel show={showLabels}>Notifications</SidebarLabel>
+  </ViewTransitionLink>
+</li>
+```
+
+`const { data: unreadCount = 0 } = useUnreadCount();` at the top of AppSidebar (import from `@/hooks/queries/notifications`; `Bell` from lucide-react — add to the existing lucide import list at line ~56). Badge positioning: verify visually against the collapsed-sidebar state (`showLabels` false) — the absolute chip must remain visible on the icon in both states; tweak offsets if the icon container differs.
+
+- [ ] **Step 2: Test**
+
+Extend AppSidebar.test.tsx: mock `@/hooks/queries/notifications` `useUnreadCount` to return `{ data: 5 }`; assert the rendered sidebar contains a link to `/notifications` showing "5". Follow the file's existing mock arrangement for other hooks.
+
+- [ ] **Step 3: Run, typecheck, commit**
+
+```bash
+cd web && pnpm exec vitest run src/components/AppSidebar.test.tsx 2>&1 | tail -4
+git add src/components/AppSidebar.* && git commit -m "feat(web): notifications sidebar item with unread badge"

+
+### Task 6: Inbox page + route
+
+**Files:**
+- Create: `web/src/pages/Notifications.tsx`
+- Test: `web/src/pages/Notifications.test.tsx`
+- Modify: `web/src/App.tsx` (user routes block ~line 331+)
+
+- [ ] **Step 1: Failing test**
+
+Mock the notifications query hooks. Assertions:
+- renders rows for items across categories with title/body/relative time;
+- category filter tabs (All, Requests, Content, Announcements, System — admin tab only when `useAuth().user?.role === "admin"`) change the `category` filter passed to `useNotificationsList` (capture via mock);
+- unread rows visually distinct (e.g. a `data-unread="true"` attribute — assert on it);
+- per-row dismiss button calls `useDismissNotification().mutate(id)`;
+- "Load more" appears when `hasNextPage` and calls `fetchNextPage`;
+- on mount, visible unread ids are marked read: `useMarkRead().mutate({ ids: [...] })` (assert called once with the unread ids from page one).
+
+- [ ] **Step 2: Implement**
+
+Page structure (use the repo's page conventions — check an existing simple page like the History/Collections page for header/container classes):
+
+```tsx
+const CATEGORY_TABS: { key: string; label: string; adminOnly?: boolean }[] = [
+  { key: "", label: "All" },
+  { key: "request", label: "Requests" },
+  { key: "content", label: "Content" },
+  { key: "announcement", label: "Announcements" },
+  { key: "system", label: "System" },
+  { key: "admin", label: "Admin", adminOnly: true },
+];
+```
+
+- `useState` for active category; `useNotificationsList({ category })` (omit when "");
+- mark-on-view effect:
+
+```tsx
+const firstPage = list.data?.pages?.[0];
+const markRead = useMarkRead();
+const markedRef = useRef(false);
+useEffect(() => {
+  if (markedRef.current || !firstPage) return;
+  const unreadIds = (firstPage.items ?? []).filter((n) => !n.read_at).map((n) => n.id);
+  if (unreadIds.length > 0) markRead.mutate({ ids: unreadIds });
+  markedRef.current = true;
+}, [firstPage, markRead]);
+```
+
+- rows: title, body, `created_at` rendered with the repo's existing relative-time helper (grep `formatDistance\|relativeTime\|timeAgo` in web/src/lib — use what exists; if nothing, use `Intl.RelativeTimeFormat` inline helper in the page);
+- dismiss button (X icon) per row; "Mark all read" header button; "Load more" via `fetchNextPage` when `hasNextPage`;
+- empty state per tab.
+
+- [ ] **Step 3: Route**
+
+In `App.tsx`, register alongside the other authenticated user pages (match the guard used by e.g. the favorites/history page — likely inside the layout route with profile required):
+
+```tsx
+<Route path="/notifications" element={<Notifications />} />
+```
+
+(Lazy-load if neighboring pages are lazy — match the file's import pattern.)
+
+- [ ] **Step 4: Tests, typecheck, commit**
+
+```bash
+cd web && pnpm exec vitest run src/pages/Notifications.test.tsx 2>&1 | tail -5 && pnpm exec tsc -b --noEmit 2>&1 | head -3
+git add src/pages/Notifications.* src/App.tsx && git commit -m "feat(web): notifications inbox page"
+```
+
+---
+
+### Task 7: Settings preferences section
+
+**Files:**
+- Create: `web/src/pages/settings/NotificationsSettings.tsx`
+- Modify: `web/src/pages/SettingsLayout.tsx` (NAV_SECTIONS), `web/src/App.tsx` (settings child route)
+
+- [ ] **Step 1: Implement the settings page**
+
+Template: `web/src/pages/settings/PlaybackSettings.tsx` (SettingsGroup/SettingRow/Switch composition). Content:
+
+```tsx
+const PREF_LABELS: Record<string, { label: string; description: string; adminOnly?: boolean }> = {
+  request: { label: "Requests", description: "Updates when your requests are approved, declined, or ready" },
+  content: { label: "New content", description: "New arrivals matching your watchlist, favorites, and shows in progress" },
+  system: { label: "Account & security", description: "Password changes and account notices" },
+  admin: { label: "Admin alerts", description: "Failed jobs and scans (admins only)", adminOnly: true },
+  content_digest: { label: "Daily digest", description: "One daily summary of everything added to your libraries" },
+};
+```
+
+- `useNotificationPreferences()` for current values; render a `Switch` per category in PREF_LABELS order, skipping `adminOnly` entries when `useAuth().user?.role !== "admin"`;
+- on toggle: `useSetNotificationPreferences().mutate([{ category, enabled }])` (single-category PUT — server upserts per row);
+- note under the group: "Announcements from your server admin can't be turned off."
+
+- [ ] **Step 2: Register in SettingsLayout NAV_SECTIONS**
+
+Add a "Notifications" section (icon `Bell`) pointing at path `notifications`, following the structure at SettingsLayout.tsx lines 39-100. Register the child route in App.tsx where other settings pages are routed (find `PlaybackSettings` route registration and mirror it).
+
+- [ ] **Step 3: Test**
+
+Extend `web/src/pages/SettingsLayout.test.tsx` if it asserts nav items (check); add `NotificationsSettings` rendering test only if sibling settings pages have tests (check `ls web/src/pages/settings/*.test.tsx`) — match local convention; if none exist, rely on the layout test + typecheck (note this in the commit message).
+
+- [ ] **Step 4: Typecheck, test, commit**
+
+```bash
+cd web && pnpm exec tsc -b --noEmit 2>&1 | head -3 && pnpm exec vitest run src/pages/SettingsLayout.test.tsx 2>&1 | tail -4
+git add src/pages/settings/NotificationsSettings.tsx src/pages/SettingsLayout.tsx src/App.tsx
+git commit -m "feat(web): notification preference toggles in settings"
+```
+
+---
+
+### Task 8: Admin announcements page
+
+**Files:**
+- Create: `web/src/pages/AdminAnnouncements.tsx`
+- Modify: `web/src/components/AdminSidebar.tsx` (nav items ~lines 81-134), `web/src/App.tsx` (admin routes ~lines 363-398)
+
+- [ ] **Step 1: Implement the page**
+
+Template: `web/src/pages/AdminUsers.tsx` for the table + dialog patterns (read it first; reuse its Table/Dialog/Button composition). Features:
+
+- Table of announcements: title, audience summary ("Everyone" / "N users" / "Libraries: a, b"), created date, expires date, delete button with confirm dialog ("Deleting dismisses unread copies from user inboxes.").
+- "New announcement" button → Dialog with: title (Input, required), body (Textarea), audience radio group (Everyone / Specific users / Libraries) — for "Specific users" a multi-select of users (check how AdminUsers fetches the user list — reuse that hook; if a multi-select primitive is missing, comma-separated ids input is NOT acceptable — use checkboxes in a scrollable list), for Libraries the same against the libraries list hook (grep `useLibraries` in hooks/queries) — optional `expires_at` datetime-local input.
+- Submit via `useCreateAnnouncement()`; disable submit until title non-empty and a valid audience selection exists.
+
+- [ ] **Step 2: Nav + route**
+
+AdminSidebar: add item (icon `Megaphone` from lucide-react) labeled "Announcements" → `/admin/announcements`, following the existing items' structure. App.tsx admin routes: `<Route path="announcements" element={<AdminAnnouncements />} />`.
+
+- [ ] **Step 3: Test**
+
+`web/src/pages/AdminAnnouncements.test.tsx` — mock the three admin hooks; assert: table renders rows incl. audience summaries; create dialog validates (submit disabled with empty title); submitting with Everyone calls `useCreateAnnouncement().mutate` with `{audience: {all: true}, ...}`; delete confirm calls `useDeleteAnnouncement().mutate(id)`.
+
+- [ ] **Step 4: Tests, typecheck, commit**
+
+```bash
+cd web && pnpm exec vitest run src/pages/AdminAnnouncements.test.tsx 2>&1 | tail -5 && pnpm exec tsc -b --noEmit 2>&1 | head -3
+git add src/pages/AdminAnnouncements.* src/components/AdminSidebar.tsx src/App.tsx
+git commit -m "feat(web): admin announcements management page"
+```
+
+---
+
+### Task 9: Full verification
+
+- [ ] **Step 1: Web checks**
+
+```bash
+cd web && pnpm run lint && pnpm run format:check && pnpm exec vitest run 2>&1 | tail -6 && pnpm run build 2>&1 | tail -4
+```
+
+All green; build also refreshes `web/dist` so the Go embed keeps working.
+
+- [ ] **Step 2: Backend still green**
+
+```bash
+GOWORK=off go build ./... && GOWORK=off go test ./internal/api/handlers/ 2>&1 | tail -2
+make verify-local-paths
+```
+
+- [ ] **Step 3: E2E smoke against the dev stack**
+
+```bash
+docker compose up -d postgres redis
+GOWORK=off go build -o /tmp/silo-web-e2e ./cmd/silo && /tmp/silo-web-e2e &
+```
+
+In a browser (or report for manual check): log in, confirm the sidebar Notifications item + mobile bell render; create an announcement in /admin/announcements; verify toast fires live (WS) and badge increments without reload; open inbox, rows mark read, badge clears; toggle a preference off and verify it persists after reload.
+
+- [ ] **Step 4: Commit anything outstanding; report**
+
+---
+
+## Self-review notes
+
+- Desktop bell+dropdown from the spec adapted to a sidebar nav item + badge (no desktop top bar exists in this app); the dropdown ships on the mobile header bell. Spec intent (always-visible unread indicator + 1-click access) preserved.
+- Toast child/profile filtering is client-side by necessity (WS frames are user-scoped; see spec Future work on claims enrichment) — `useNotificationsLive` suppresses other-profile and child-restricted frames.
+- `content_digest` rows arrive as category `content` (server stores digest as content/content.digest) — the inbox Content tab includes them; the preferences page exposes the separate `content_digest` toggle. No UI filters by `content_digest` category (final server review noted this trap).
+- Mark-on-view marks only page one's unread ids once per mount — deliberate; deeper pages mark via "Mark all read".
+- Several steps include verify-greps (ui primitive names, Link import source, relative-time helper, settings test conventions, multi-select availability) — implementers must align with what exists rather than invent.

+# Core Push — Web Client & Admin Config — Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Make push operable end-to-end from the browser: a Web Push client (service worker, subscribe, receive, per-device control, device list) plus an admin provider-config page (APNs/FCM/WebPush credentials, VAPID keygen, readiness), on top of the frozen push API.
+
+**Architecture:** Five web units + two small Go endpoints. A static service worker receives pushes; a `usePushDevice` hook owns the browser subscription lifecycle; the existing notifications-settings page gains a push control + device list; a new admin page reuses the existing encrypted-settings write path for credentials. Two net-new server endpoints: VAPID keygen and a self-targeted test push.
+
+**Tech Stack:** React 19, TanStack Query, sonner, the existing api client (auto device/profile headers), browser Push API / Service Worker / Notifications API, Go (chi), webpush-go (already a dep). Vitest + RTL.
+
+**Spec:** `docs/superpowers/specs/2026-06-10-core-push-web-client-design.md`. The push registration API + delivery worker are frozen (Phase-3-server).
+
+Commands assume the repository root is the cwd; web commands run in `web/` with `pnpm`. Go: `export GOWORK=off`.
+
+## Frozen API the client calls
+
+```
+GET    /api/v1/notifications/push/webpush-key          → {vapid_public_key}
+PUT    /api/v1/notifications/push/device  {transport, token}   → 204  (needs X-Profile-Id; api client sends it)
+DELETE /api/v1/notifications/push/device                → 204
+GET    /api/v1/notifications/push/devices               → {devices:[{device_id,name,platform,transport,push_enabled,registered_at}]}
+PUT    /api/v1/notifications/push/devices/{device_id} {enabled}  → 204
+GET    /api/v1/admin/push/status                        → {apns,fcm,webpush: bool}
+PUT    /api/v1/admin/settings/{key}  {value}            → writes an encrypted push.* key (existing)
+GET    /api/v1/admin/settings/sensitive-status          → {configured:[keys]}  (existing)
+```
+
+Net-new this plan: `POST /api/v1/admin/push/generate-vapid-keys` and `POST /api/v1/admin/push/test`.

+
+### Task 1: Server endpoints — VAPID keygen + test push
+
+**Files:**
+- Modify: `internal/api/handlers/push.go`, `internal/api/router.go`, `cmd/silo/main.go`
+- Test: `internal/api/handlers/push_test.go`
+
+- [ ] **Step 1: Add a notifier dep + the two handlers**
+
+In `push.go`, add a narrow interface and a field on `PushHandler`:
+
+```go
+// pushNotifier creates a notification for the calling user (test push).
+type pushNotifier interface {
+	CreateSystem(ctx context.Context, userID int, typ, title, body string)
+}
+```
+
+Add `notifier pushNotifier` to `PushHandler` and a parameter to `NewPushHandler` (nil-tolerant — test-push 503s if absent). `*notifications.Service` satisfies `pushNotifier` (it has `CreateSystem(ctx, userID int, typ, title, body string)` from Phase-1).
+
+Handlers:
+
+```go
+func (h *PushHandler) HandleGenerateVAPIDKeys(w http.ResponseWriter, r *http.Request) {
+	priv, pub, err := webpush.GenerateVAPIDKeys()
+	if err != nil {
+		writeError(w, http.StatusInternalServerError, "internal_error", "failed to generate keys")
+		return
+	}
+	writeJSON(w, http.StatusOK, map[string]string{"vapid_public": pub, "vapid_private": priv})
+}
+
+func (h *PushHandler) HandleSendTestPush(w http.ResponseWriter, r *http.Request) {
+	if h.notifier == nil {
+		writeError(w, http.StatusServiceUnavailable, "unavailable", "notifications unavailable")
+		return
+	}
+	userID := apimw.GetUserID(r.Context())
+	if userID == 0 {
+		writeError(w, http.StatusUnauthorized, "unauthorized", "auth required")
+		return
+	}
+	h.notifier.CreateSystem(r.Context(), userID,
+		"system.test_push", "Test push",
+		"If you can see this on a device, push delivery is working.")
+	w.WriteHeader(http.StatusAccepted)
+}
+```
+
+Import `webpush "github.com/SherClockHolmes/webpush-go"`. **Verify the `GenerateVAPIDKeys()` return order** against the installed version — webpush-go returns `(privateKey, publicKey string, err error)`. Confirm by reading the vendored signature or `go doc`; if it's `(public, private, err)` swap accordingly. Get this right — swapping the keys silently breaks push.
+
+- [ ] **Step 2: Routes**
+
+In `router.go`, in the admin push block (next to `r.Get("/push/status", ...)`, ~line 2295, behind `deps.PushStore != nil`):
+
+```go
+r.Post("/push/generate-vapid-keys", pushHandler.HandleGenerateVAPIDKeys)
+r.Post("/push/test", pushHandler.HandleSendTestPush)
+```
+
+- [ ] **Step 3: Wire the notifier**
+
+Update every `NewPushHandler(...)` call site (find with grep) to pass the notifications service. In `cmd/silo/main.go` and/or `router.go` where the push handler is constructed, add `deps.NotificationsService` (or the in-scope `notificationsSvc`) as the third arg. Build will tell you the sites.
+
+- [ ] **Step 4: Tests**
+
+Add to `push_test.go` (reuse the package's fakes / chi-request helper from Task-13 push tests):
+
+```go
+func TestPushHandleGenerateVAPIDKeys_ReturnsPair(t *testing.T) {
+	h := NewPushHandler(&fakePushRegistry{}, &fakePushConfig{}, nil)
+	rr := httptest.NewRecorder()
+	h.HandleGenerateVAPIDKeys(rr, httptest.NewRequest(http.MethodPost, "/", nil))
+	if rr.Code != http.StatusOK {
+		t.Fatalf("code = %d", rr.Code)
+	}
+	var body map[string]string
+	_ = json.Unmarshal(rr.Body.Bytes(), &body)
+	if body["vapid_public"] == "" || body["vapid_private"] == "" || body["vapid_public"] == body["vapid_private"] {
+		t.Fatalf("bad key pair: %+v", body)
+	}
+}
+
+type fakeNotifier struct{ called bool; userID int; typ string }
+
+func (f *fakeNotifier) CreateSystem(_ context.Context, userID int, typ, _, _ string) {
+	f.called = true
+	f.userID = userID
+	f.typ = typ
+}
+
+func TestPushHandleSendTestPush_CreatesForCaller(t *testing.T) {
+	n := &fakeNotifier{}
+	h := NewPushHandler(&fakePushRegistry{}, &fakePushConfig{}, n)
+	r := httptest.NewRequest(http.MethodPost, "/", nil)
+	r = r.WithContext(apimw.SetUserID(r.Context(), 7)) // use the package's claims-injection helper if SetUserID differs
+	rr := httptest.NewRecorder()
+	h.HandleSendTestPush(rr, r)
+	if rr.Code != http.StatusAccepted || !n.called || n.userID != 7 || n.typ != "system.test_push" {
+		t.Fatalf("unexpected: code=%d notifier=%+v", rr.Code, n)
+	}
+}
+
+func TestPushHandleSendTestPush_NilNotifier503(t *testing.T) {
+	h := NewPushHandler(&fakePushRegistry{}, &fakePushConfig{}, nil)
+	rr := httptest.NewRecorder()
+	h.HandleSendTestPush(rr, httptest.NewRequest(http.MethodPost, "/", nil))
+	if rr.Code != http.StatusServiceUnavailable {
+		t.Fatalf("code = %d", rr.Code)
+	}
+}
+```
+
+Check how the existing push tests inject the user id into context (Task-13 used a claims/`apimw` helper — mirror it; `apimw.SetUserID` may not exist, use whatever the package's tests already use to set `GetUserID`).
+
+- [ ] **Step 5: Build, test, commit**
+
+```bash
+GOWORK=off go build ./... && GOWORK=off go test ./internal/api/handlers/ -run TestPush -v 2>&1 | tail -8 && GOWORK=off go vet ./internal/api/handlers/
+git add internal/api/handlers/push.go internal/api/handlers/push_test.go internal/api/router.go cmd/silo/main.go
+git commit -m "feat(push): admin VAPID keygen and self-test endpoints"
+```
+
+---
+
+### Task 2: Service worker + registration + helpers
+
+**Files:**
+- Create: `web/public/sw.js`, `web/src/lib/pushSw.ts`, `web/src/lib/push.ts`
+- Test: `web/src/lib/pushSw.test.ts`, `web/src/lib/push.test.ts`
+- Modify: `web/src/main.tsx`
+
+- [ ] **Step 1: Pure SW logic (tested) — `web/src/lib/pushSw.ts`**
+
+```ts
+export interface PushPayload {
+  id?: number;
+  title?: string;
+  body?: string;
+  link?: string;
+  category?: string;
+}
+
+export interface SwNotification {
+  title: string;
+  options: { body: string; data: { link: string }; tag: string };
+}
+
+/** Maps a raw push payload to showNotification args; tolerant of partial/missing fields. */
+export function buildNotification(payload: PushPayload | null): SwNotification {
+  const p = payload ?? {};
+  const link = p.link && p.link.length > 0 ? p.link : "/notifications";
+  const tag = p.id != null ? `n${p.id}` : "n";
+  return {
+    title: p.title && p.title.length > 0 ? p.title : "Silo",
+    options: { body: p.body ?? "", data: { link }, tag },
+  };
+}
+
+/** The URL a notification click should open/focus. */
+export function clickUrl(data: unknown): string {
+  const d = (data ?? {}) as { link?: string };
+  return d.link && d.link.length > 0 ? d.link : "/notifications";
+}
+```
+
+- [ ] **Step 2: Test it — `web/src/lib/pushSw.test.ts`**
+
+```ts
+import { describe, expect, it } from "vitest";
+import { buildNotification, clickUrl } from "./pushSw";
+
+describe("buildNotification", () => {
+  it("maps a full payload", () => {
+    const n = buildNotification({ id: 5, title: "Approved", body: "Dune", link: "/requests" });
+    expect(n.title).toBe("Approved");
+    expect(n.options).toEqual({ body: "Dune", data: { link: "/requests" }, tag: "n5" });
+  });
+  it("falls back on missing fields", () => {
+    const n = buildNotification(null);
+    expect(n.title).toBe("Silo");
+    expect(n.options.body).toBe("");
+    expect(n.options.data.link).toBe("/notifications");
+    expect(n.options.tag).toBe("n");
+  });
+});
+
+describe("clickUrl", () => {
+  it("uses link when present", () => expect(clickUrl({ link: "/items/9" })).toBe("/items/9"));
+  it("falls back to inbox", () => expect(clickUrl({})).toBe("/notifications"));
+});
+```
+
+Run: `pnpm exec vitest run src/lib/pushSw.test.ts` → green.
+
+- [ ] **Step 3: The static service worker — `web/public/sw.js`**
+
+Self-contained (served statically, not bundled). Mirror the pure logic exactly (the canonical, tested source is `pushSw.ts`):
+
+```js
+// web/public/sw.js — static service worker for Web Push.
+// NOTE: the buildNotification/clickUrl logic mirrors src/lib/pushSw.ts (the
+// tested source of truth). Keep them in sync.
+
+function buildNotification(payload) {
+  const p = payload || {};
+  const link = p.link && p.link.length > 0 ? p.link : "/notifications";
+  const tag = p.id != null ? "n" + p.id : "n";
+  return {
+    title: p.title && p.title.length > 0 ? p.title : "Silo",
+    options: { body: p.body || "", data: { link: link }, tag: tag },
+  };
+}
+function clickUrl(data) {
+  const d = data || {};
+  return d.link && d.link.length > 0 ? d.link : "/notifications";
+}
+
+self.addEventListener("push", (event) => {
+  let payload = null;
+  try {
+    payload = event.data ? event.data.json() : null;
+  } catch (e) {
+    payload = null;
+  }
+  const n = buildNotification(payload);
+  event.waitUntil(self.registration.showNotification(n.title, n.options));
+});
+
+self.addEventListener("notificationclick", (event) => {
+  event.notification.close();
+  const url = clickUrl(event.notification.data);
+  event.waitUntil(
+    self.clients.matchAll({ type: "window", includeUncontrolled: true }).then((wins) => {
+      for (const c of wins) {
+        if ("focus" in c) {
+          c.postMessage({ type: "notification-click", link: url });
+          return c.focus();
+        }
+      }
+      return self.clients.openWindow(url);
+    }),
+  );
+});
+
+self.addEventListener("pushsubscriptionchange", (event) => {
+  // Best-effort re-subscribe using the cached VAPID key; the app re-registers
+  // the new subscription on next load if this fails.
+  event.waitUntil(
+    (async () => {
+      try {
+        const cache = await caches.open("silo-push");
+        const res = await cache.match("vapid-public-key");
+        if (!res) return;
+        const vapid = await res.text();
+        const sub = await self.registration.pushManager.subscribe({
+          userVisibleOnly: true,
+          applicationServerKey: vapid,
+        });
+        await fetch("/api/v1/notifications/push/device", {
+          method: "PUT",
+          headers: { "Content-Type": "application/json" },
+          credentials: "include",
+          body: JSON.stringify({ transport: "webpush", token: JSON.stringify(sub.toJSON()) }),
+        });
+      } catch (e) {
+        // swallow; app re-registers on next load
+      }
+    })(),
+  );
+});
+```
+
+Note: the `pushsubscriptionchange` re-register relies on cookie auth (`credentials: include`) and the device/profile headers it can't set from the SW — it is genuinely best-effort and the app heals it on next load (documented in the spec). `applicationServerKey` accepts a base64url string in modern browsers; if the target browsers need a Uint8Array here, the app-side path (Task 4) converts it — the SW path is the fallback and may no-op on stricter browsers, which is acceptable.
+
+- [ ] **Step 4: App-side helpers — `web/src/lib/push.ts`**
+
+```ts
+/** Convert a base64url VAPID public key to the Uint8Array applicationServerKey wants. */
+export function urlBase64ToUint8Array(base64: string): Uint8Array {
+  const padding = "=".repeat((4 - (base64.length % 4)) % 4);
+  const b64 = (base64 + padding).replace(/-/g, "+").replace(/_/g, "/");
+  const raw = atob(b64);
+  const out = new Uint8Array(raw.length);
+  for (let i = 0; i < raw.length; i++) out[i] = raw.charCodeAt(i);
+  return out;
+}
+
+/** Cache the raw VAPID public key so the SW can re-subscribe without the app. */
+export async function cacheVapidKey(base64: string): Promise<void> {
+  if (!("caches" in self)) return;
+  const cache = await caches.open("silo-push");
+  await cache.put("vapid-public-key", new Response(base64));
+}
+

+    "Notification" in window
+  );
+}

+
+- [ ] **Step 5: Test the converter — `web/src/lib/push.test.ts`**
+
+```ts
+import { describe, expect, it } from "vitest";
+import { urlBase64ToUint8Array } from "./push";
+
+describe("urlBase64ToUint8Array", () => {
+  it("decodes a url-safe base64 key to bytes", () => {
+    // "AQID" → [1,2,3]
+    expect(Array.from(urlBase64ToUint8Array("AQID"))).toEqual([1, 2, 3]);
+  });
+  it("handles url-safe chars and missing padding", () => {
+    const out = urlBase64ToUint8Array("a-_9"); // '-'→'+', '_'→'/'
+    expect(out.length).toBe(3);
+  });
+});
+```
+
+- [ ] **Step 6: Register the SW — `web/src/main.tsx`**
+
+After `createRoot(...).render(...)`, add:
+
+```tsx
+if ("serviceWorker" in navigator && "PushManager" in window) {
+  window.addEventListener("load", () => {
+    navigator.serviceWorker.register("/sw.js").catch(() => {
+      // registration failure is non-fatal; push just won't be available
+    });
+  });
+}
+```
+
+- [ ] **Step 7: Run, build, commit**
+
+```bash
+cd web && pnpm exec vitest run src/lib/pushSw.test.ts src/lib/push.test.ts 2>&1 | tail -5 && pnpm exec tsc -b --noEmit 2>&1 | head -3
+git add web/public/sw.js web/src/lib/pushSw.ts web/src/lib/pushSw.test.ts web/src/lib/push.ts web/src/lib/push.test.ts web/src/main.tsx

+
+### Task 3: Push query hooks + types
+
+**Files:**
+- Modify: `web/src/api/types.ts`
+- Create: `web/src/hooks/queries/push.ts`
+- Modify: `web/src/hooks/queries/keys.ts` (add `pushKeys`)
+
+- [ ] **Step 1: Types** — append to `types.ts`:
+
+```ts
+export interface PushDeviceInfo {
+  device_id: string;
+  name: string;
+  platform: string;
+  transport: string;
+  push_enabled: boolean;
+  registered_at?: string;
+}
+
+export interface VapidKeyPair {
+  vapid_public: string;
+  vapid_private: string;
+}
+```
+
+- [ ] **Step 2: Keys** — in `keys.ts`:
+
+```ts
+export const pushKeys = {
+  all: ["push"] as const,
+  webpushKey: () => [...pushKeys.all, "webpush-key"] as const,
+  devices: () => [...pushKeys.all, "devices"] as const,
+  status: () => [...pushKeys.all, "status"] as const,
+};
+```
+
+- [ ] **Step 3: Hooks — `web/src/hooks/queries/push.ts`**
+
+Mirror `admin/users.ts` conventions (api import, toast, invalidation).
+
+```ts
+import { useMutation, useQuery, useQueryClient } from "@tanstack/react-query";
+import { toast } from "sonner";
+
+import { api } from "@/api/client";
+import type { PushDeviceInfo, VapidKeyPair } from "@/api/types";
+import { pushKeys } from "@/hooks/queries/keys";
+
+export function useWebPushPublicKey() {
+  return useQuery({
+    queryKey: pushKeys.webpushKey(),
+    queryFn: () => api<{ vapid_public_key: string }>("/notifications/push/webpush-key"),
+    select: (d) => d.vapid_public_key,
+    staleTime: 5 * 60 * 1000,
+  });
+}
+
+export function usePushDevices() {
+  return useQuery({
+    queryKey: pushKeys.devices(),
+    queryFn: () => api<{ devices: PushDeviceInfo[] | null }>("/notifications/push/devices"),
+    select: (d) => d.devices ?? [],
+  });
+}
+
+export function useTogglePushDevice() {
+  const qc = useQueryClient();
+  return useMutation({
+    mutationFn: ({ deviceId, enabled }: { deviceId: string; enabled: boolean }) =>
+      api(`/notifications/push/devices/${deviceId}`, {
+        method: "PUT",
+        body: JSON.stringify({ enabled }),
+      }),
+    onSuccess: () => void qc.invalidateQueries({ queryKey: pushKeys.devices() }),
+    onError: (err) => toast.error(err instanceof Error ? err.message : "Failed to update device"),
+  });
+}
+
+export function usePushStatus() {
+  return useQuery({
+    queryKey: pushKeys.status(),
+    queryFn: () => api<{ apns: boolean; fcm: boolean; webpush: boolean }>("/admin/push/status"),
+  });
+}
+
+export function useGenerateVapidKeys() {
+  return useMutation({
+    mutationFn: () => api<VapidKeyPair>("/admin/push/generate-vapid-keys", { method: "POST" }),
+    onError: (err) => toast.error(err instanceof Error ? err.message : "Failed to generate keys"),
+  });
+}
+
+export function useSendTestPush() {
+  return useMutation({
+    mutationFn: () => api("/admin/push/test", { method: "POST" }),
+    onSuccess: () => toast.success("Test push queued — watch for a banner"),
+    onError: (err) => toast.error(err instanceof Error ? err.message : "Failed to send test"),
+  });
+}
+```
+
+(Register/revoke device calls live inside `usePushDevice` (Task 4) since they're tied to the subscription, not standalone query hooks.)

+
+### Task 5: NotificationsSettings — push control + device list
+
+**Files:**
+- Modify: `web/src/pages/settings/NotificationsSettings.tsx`
+- Test: extend the page's test if one exists (check `ls web/src/pages/settings/*.test.tsx`)
+
+- [ ] **Step 1: Add a push section**
+
+Read the current `NotificationsSettings.tsx` (it uses `SettingsGroup`/`SettingRow`/`Switch`). Add, below the category-preference group, a new "Push notifications" group:
+
+- A row driven by `usePushDevice()`:
+  - `status === "unsupported"` → static text "This browser doesn't support push notifications."
+  - `status === "blocked"` → text "Notifications are blocked for this site. Re-enable them in your browser's site settings."
+  - else → a `Switch` checked when `status === "on"`, disabled when `status === "pending"`, `onCheckedChange` calls `enable()` / `disable()`.
+- Below it, a device list from `usePushDevices()`: one row per device (`name || device_id`, `platform`/`transport`, `registered_at`), each with a `Switch` bound to `useTogglePushDevice().mutate({ deviceId, enabled })` reflecting `push_enabled`. Empty state: "No devices registered for push yet."
+
+Match the page's existing component composition and classes. Keep `content_digest` and the existing toggles untouched.
+
+- [ ] **Step 2: Test (if the page is tested)**
+
+If `NotificationsSettings.test.tsx` exists, mock `usePushDevice` (return `{status:"off", enable, disable}`) and `usePushDevices` (two devices); assert: toggling the device-level switch calls `useTogglePushDevice().mutate` with the device id; the main push switch calls `enable` when off. If no sibling test exists, rely on typecheck + the hook tests and note it in the commit.
+
+- [ ] **Step 3: Typecheck, test, commit**
+
+```bash
+cd web && pnpm exec tsc -b --noEmit 2>&1 | head -3 && pnpm exec vitest run src/pages/settings 2>&1 | tail -4
+git add web/src/pages/settings/NotificationsSettings.tsx web/src/pages/settings/*.test.tsx
+git commit -m "feat(web): push on-this-device control and device list in settings"
+```
+
+---
+
+### Task 6: Admin PushSettings page + nav
+
+**Files:**
+- Create: `web/src/pages/admin-settings/PushSettings.tsx`
+- Modify: `web/src/pages/admin-settings/AdminSettingsLayout.tsx`
+- Test: `web/src/pages/admin-settings/PushSettings.test.tsx`
+
+- [ ] **Step 1: Build the page**
+
+Template: `IntegrationsSettings.tsx` (credential card = `CredentialStatus` badge + `SettingField` + `useUpdateServerSetting` + `useAdminSensitiveStatus`). Three cards. Header badge per card from `usePushStatus()`.
+
+- **Web Push card** (leads): fields `push.webpush.vapid_public`, `push.webpush.vapid_private`, `push.webpush.subject`. A "Generate keys" button → `useGenerateVapidKeys().mutateAsync()` fills the public + private field state (local `useState`, not auto-saved). Subject field hint: `mailto:you@example.com`. Each field saves via `updateSetting.mutateAsync({ key, value })`. A "Send test push" button → `useSendTestPush().mutate()`.
+- **APNs card**: `push.apns.p8_key` (textarea via `SettingField` multiline if supported, else a `<textarea>`), `push.apns.key_id`, `push.apns.team_id`, `push.apns.bundle_id`.
+- **FCM card**: `push.fcm.service_account_json` (textarea).
+
+`configured` per field from `new Set(sensitive?.configured ?? []).has(key)`. Page header + intro like IntegrationsSettings.
+
+- [ ] **Step 2: Register nav**
+
+In `AdminSettingsLayout.tsx`, add to the "Connections" group's `items` (import the component + a lucide icon, e.g. `BellRing`):
+
+```tsx
+{ id: "push", label: "Push Notifications", icon: BellRing, component: PushSettings },
+```
+
+(`id: "push"` is stable URL state.)
+
+- [ ] **Step 3: Test — `PushSettings.test.tsx`**
+
+Mock `useUpdateServerSetting` (capture mutate args), `useAdminSensitiveStatus` (some keys configured), `usePushStatus` (webpush true), `useGenerateVapidKeys` (returns a pair), `useSendTestPush`. Assert: three cards render; webpush badge shows ready; saving the VAPID public field calls `updateSetting.mutateAsync({ key: "push.webpush.vapid_public", value })`; "Generate keys" populates the public/private fields; "Send test push" calls the mutation. Follow the admin-settings test conventions (check a sibling `*.test.tsx` in that dir; if none, write a minimal RTL test with the mocks).
+
+- [ ] **Step 4: Typecheck, test, build, commit**
+
+```bash
+cd web && pnpm exec tsc -b --noEmit 2>&1 | head -3 && pnpm exec vitest run src/pages/admin-settings 2>&1 | tail -5
+git add web/src/pages/admin-settings/PushSettings.tsx web/src/pages/admin-settings/PushSettings.test.tsx web/src/pages/admin-settings/AdminSettingsLayout.tsx
+git commit -m "feat(web): admin push provider config page"
+```
+
+---
+
+### Task 7: Full verification + manual smoke
+
+- [ ] **Step 1: Web gates**
+
+```bash
+cd web && pnpm run lint 2>&1 | tail -3 && pnpm run format:check 2>&1 | tail -2 && pnpm exec vitest run 2>&1 | tail -5 && pnpm run build 2>&1 | tail -3
+```
+
+All green (lint warnings allowed, errors not). Fix any new-code lint/format issues (prettier --write the new files if format:check flags them). `build` also confirms `public/sw.js` is copied to `dist/` (Vite copies `public/` verbatim).
+
+- [ ] **Step 2: Backend gates**
+
+```bash
+GOWORK=off go build ./... && GOWORK=off go test ./internal/api/handlers/ -run TestPush 2>&1 | tail -3 && make verify-local-paths
+```
+
+- [ ] **Step 3: Manual browser smoke (documented; requires a real browser over HTTPS or localhost)**
+
+Service workers + Push require a secure context — `localhost` qualifies. Build the server with the web assets and run on a localhost port.
+Commands assume the repository root is the cwd.
+
+```bash
+cd web && pnpm run build && cd ..
+GOWORK=off go build -o ./bin/silo-pushweb ./cmd/silo && (PORT=18080 JF_PORT=18096 ./bin/silo-pushweb > ./silo-pushweb.log 2>&1 &)
+```
+
+Then in a Chromium browser at `http://localhost:18080`:
+1. Log in as admin. Go to Admin → Settings → Push Notifications. Click "Generate keys", Save the VAPID public/private + a `mailto:` subject. Confirm the Web Push badge flips to "Ready" (and `GET /admin/push/status` → webpush:true).
+2. Go to Settings → Notifications. Toggle "Push on this device" on → grant the browser permission prompt. Confirm a row appears in the device list and the toggle stays on.
+3. Click "Send test push" on the admin page (or create an announcement). Within ~30–45s (grace + worker tick) a desktop notification banner appears. Close the app tab first to prove background delivery.
+4. Click the banner → the app opens/focuses at the deep link.
+5. Toggle push off → confirm `DELETE` and the device drops from the list.
+
+Record the outcome. (If a real browser isn't available in the harness, run steps 1–2 via curl to confirm the API wiring — register a webpush device, confirm `push_deliveries` row + status — and note the visual steps as operator-verified.)
+
+- [ ] **Step 4: Commit any verification fixes; report.** Work stays on `feat/core-notifications-server` (or a dedicated branch off it).
+
+---
+
+## Self-review notes (resolved during writing)
+
+- `webpush.GenerateVAPIDKeys()` returns `(privateKey, publicKey, err)` in webpush-go — Task 1 Step 1 flags verifying the order so the keys aren't swapped.
+- The SW's pure logic is duplicated between `public/sw.js` (untestable static file) and the tested `src/lib/pushSw.ts`; the duplication is small and intentional, with sw.js annotated as mirroring the tested source. The reviewer should diff the two functions for drift.
+- `usePushDevice` owns register/revoke (tied to the live subscription); standalone query hooks (`push.ts`) cover read/list/toggle/admin. No overlap.
+- Test push reuses `notifications.Service.CreateSystem` (Phase-1) → a real system notification → exercises the full enqueue→worker→transport pipeline to the caller's own devices. No bespoke push path.
+- Admin credential writes use the existing `PUT /admin/settings/{key}` (encrypted, redacted) — no new write endpoint; only keygen + test are net-new server surface.
+- iOS Safari web push (installed-PWA only) is handled by `pushSupported()` returning false in a normal tab → `unsupported` state; documented, not specially coded.
+- Several steps embed verify-greps (NewPushHandler call sites, GenerateVAPIDKeys order, SettingField multiline support, sibling test conventions, the user-id context injection helper in push_test.go) — align with reality.

+# Core Notifications System — Design
+
+Date: 2026-06-10
+Status: approved (design); implementation plan to follow
+
+## Summary
+
+A first-party, whole-system notification layer for Silo: persisted per-user notifications with an inbox, read state, per-category preferences, real-time toasts over the existing event WebSocket, and admin announcements. Ships across the server, web UI, and both mobile apps (in-app only — no APNs/FCM push in this project). External delivery (Discord, email, webhooks) remains the job of the existing `silo.notifications` plugin, which consumes the same events.
+
+## Goals
+
+- Persisted per-user notifications: inbox, unread badge, read/dismiss state.
+- Real-time in-app delivery to connected clients via the existing `events.Hub` / `/api/v1/events/ws` pipeline.
+- Five categories: `request`, `content`, `announcement`, `system`, `admin` (operational alerts for admin users), plus opt-in `content_digest`.
+- Per-category user preferences (announcements not mutable).
+- Admin announcements with audience targeting and expiry.
+- A documented `notifications.send` event contract so any plugin can create in-app notifications (and, via the existing external plugin's subscription to the same event, external ones).
+- Core request lifecycle events (`request.*`) — net-new publishing from `internal/requests`, consumed by notifications and available to the requests UI.
+
+## Non-goals
+
+- Mobile push (APNs/FCM) — future project; nothing here blocks it.
+- Request-system unification (`request_router.v1`, migrating ebook/audiobook request plugins onto `media_requests`) — separate future project. When it lands, the book plugins' `notifications.send` publishes are replaced by core `request.*` events with no notifications schema/API change.
+- Absorbing external delivery channels into core.
+- Fine-grained per-show/per-author subscription rules (watchlist/favorites are the v1 signal).
+
+## Architecture
+
+New package `internal/notifications` in silo-server:
+
+1. **Materializer** — in-process consumer registered on `events.Hub` at startup (same pattern as `internal/plugins/event_dispatcher.go`). Runs events through per-category matchers; writes `notifications` rows for each recipient.
+2. **Store** — Postgres repository: insert (idempotent), list (cursor), unread count, mark read, dismiss, preferences CRUD.
+3. **Notifier** — after insert, publishes `notification.created` on a new `ChannelNotifications` event channel, user-scoped like `ChannelUserState`. The WS handler (`internal/api/handlers/events_ws.go`) adds this channel to the per-user subscribe set; frames carry the full notification object. Subscribe-time snapshot carries unread count only.
+4. **API handlers** — REST endpoints below.
+5. **Service API** — `notifications.Create(...)` for direct in-process callers (system/security events).
+
+Creation is DB-first and synchronous: a notification exists when the row commits. WS fan-out is best-effort; clients that miss frames reconcile on next fetch. No delivery queue or retry in core — "delivery" is reading your own table.
+
+## Data model
+
+One migration, three tables:
+
+```sql
+notifications (
+  id            bigserial PRIMARY KEY,
+  user_id       int NOT NULL REFERENCES users(id) ON DELETE CASCADE,
+  profile_id    text NULL REFERENCES user_profiles(id) ON DELETE CASCADE,  -- NULL = user-wide
+  category      text NOT NULL,  -- 'request' | 'content' | 'announcement' | 'system' | 'admin'
+  type          text NOT NULL,  -- e.g. 'request.approved', 'content.watchlist_episode'
+  title         text NOT NULL,
+  body          text NOT NULL,
+  link          text NULL,      -- in-app deep link
+  item_id       bigint NULL,    -- optional content reference (artwork, dedup)
+  source_event  text NULL,      -- originating event name (audit)
+  dedup_ref     text NULL,      -- idempotency: UNIQUE (user_id, type, dedup_ref) WHERE dedup_ref IS NOT NULL
+  created_at    timestamptz NOT NULL DEFAULT now(),
+  read_at       timestamptz NULL,
+  dismissed_at  timestamptz NULL,
+  expires_at    timestamptz NULL
+);
+-- index: (user_id, created_at DESC) partial WHERE dismissed_at IS NULL
+-- partial unique index for dedup as above; inserts use ON CONFLICT DO NOTHING
+
+notification_preferences (
+  user_id   int NOT NULL REFERENCES users(id) ON DELETE CASCADE,
+  category  text NOT NULL,  -- 'request' | 'content' | 'system' | 'admin' | 'content_digest'
+  enabled   bool NOT NULL,
+  PRIMARY KEY (user_id, category)
+);
+-- absent row = enabled, except content_digest which defaults OFF
+-- 'announcement' is not a valid category here (not mutable)
+
+announcements (
+  id          bigserial PRIMARY KEY,
+  title       text NOT NULL,
+  body        text NOT NULL,
+  audience    jsonb NOT NULL,  -- {"all":true} | {"user_ids":[...]} | {"library_ids":[...]}
+  created_by  int REFERENCES users(id),
+  created_at  timestamptz NOT NULL DEFAULT now(),
+  expires_at  timestamptz NULL
+);
+```
+
+Announcements fan out to `notifications` rows at publish time (audience resolved then), so the inbox is always a single-table query and read state is per-user.
+
+Child profiles: rows with `category IN ('request','system','admin')` are filtered out of child-profile sessions server-side; content matching never targets a child profile unless the matched watchlist/favorite belongs to that profile.
+
+Retention (nightly job, existing scheduler pattern): dismissed rows purged after 30 days; all rows after 90 days; unread rows from expired announcements at expiry.
+
+## API
+
+User endpoints (authenticated, profile from claims):
+
+```
+GET    /api/v1/notifications              ?unread=1&category=&cursor=&limit=
+GET    /api/v1/notifications/unread-count → {count}
+POST   /api/v1/notifications/read         {ids:[...]} | {all:true}
+POST   /api/v1/notifications/{id}/dismiss
+GET    /api/v1/notifications/preferences
+PUT    /api/v1/notifications/preferences  {category: enabled, ...}
+```
+
+List returns user-wide rows plus active-profile rows, newest first, cursor-paginated in the standard envelope. Child-profile filtering server-side.
+
+Admin endpoints (RequireAdmin group):
+
+```
+GET    /api/v1/admin/announcements
+POST   /api/v1/admin/announcements        {title, body, audience, expires_at?}
+DELETE /api/v1/admin/announcements/{id}   -- also dismisses unread fanned-out rows
+```
+
+## Events
+
+### New: core request lifecycle events
+
+`internal/requests/service.go` and the reconciliation task publish on a new `ChannelRequests`:
+
+- `request.submitted`, `request.approved`, `request.declined`, `request.completed`, `request.failed`
+- Payload: `request_id, user_id, profile_id, title, media_type, quality, status`
+
+`ChannelRequests` is added to WS subscribe sets (requesting user + admins), giving the requests UI live updates as a side benefit. This is the only change to the requests subsystem in this project.
+
+### New: `notifications.send` plugin contract
+
+The materializer consumes `notifications.send` events:
+
+```json
+{ "user_id": 1, "profile_id": null, "category": "request",
+  "type": "request.fulfilled", "title": "...", "body": "...",
+  "link": null, "dedup_ref": "ebook-req-123:fulfilled" }
+```
+
+Payloads are validated; malformed events are dropped with a logged warning. The external `silo.notifications` plugin already subscribes to this event name, so one publish reaches both in-app and external channels. The ebook/audiobook request plugins each add one `PublishEvent("notifications.send", ...)` at their acknowledged/fulfilled/failed transitions (their existing status events do not carry `user_id`; the plugins own that context).
+
+### Matchers
+
+- **request** — consumes core `request.*` events only. Dedup ref `(request_id, status)`.
+- **content** — consumes `library.item_added` / `catalog.library.changed`. For each added item: resolve series/author; match per profile against watchlist, favorites (author/series link), and in-progress series (last play within 21 days); union, dedup, filter by library access. Burst guard: one notification per series per profile per hour (season imports collapse).
+- **content_digest** — nightly job (not event-driven), opt-in: one row per user summarizing the previous day's additions to accessible libraries.
+- **system** — not matched from the hub; emitted via `notifications.Create()` directly at the source (password change, new-device login, guest-pass redemption). Sites also publish their events as today; the explicit call means security notices never depend on matcher wiring.
+- **announcement** — fan-out at publish time.
+- **admin** — consumes existing `ChannelJobs` / `ChannelScans` / `ChannelTasks` failure events plus plugin-host crash/install failures; targets admin users; repeat-failure throttle (same source, max one per hour).
+
+Preference checks run in the materializer before insert (cached per-user prefs lookup).
+
+## Web UI
+
+1. **Bell + dropdown** in the top bar: unread badge from `unread-count`, kept live by `ChannelNotifications` frames via the existing `RealtimeEventsProvider` socket. Dropdown: latest ~10, mark-all-read, deep links.
+2. **Toasts** — WS notification frames fire sonner toasts; suppressed while the dropdown is open or when the frame targets another profile.
+3. **Inbox page** (`/notifications`) — paginated list, category filter tabs, dismiss, mark-read on view.
+4. **Settings** — per-category toggles (`content_digest` default off; `admin` visible to admins only). Admin: Announcements page (list/compose/expire) under admin settings.
+
+## Mobile (in-app, both platforms)
+
+Same three features in silo-apple and silo-android against the frozen REST API: inbox screen (list, mark-read, dismiss), unread badge on existing navigation, preferences screen. Transport: REST refresh of unread-count + first page on app foreground and pull-to-refresh. No WS subscription in v1 (current app sockets are playback-scoped; no background delivery exists without push anyway). TV variants: badge + read-only inbox, no preferences editing.
+
+## Error handling
+
+- Matcher isolation: a panic/error in one matcher logs and skips that event for that matcher only; never blocks the hub or other matchers (same containment as the plugin event dispatcher).
+- Idempotent inserts via the dedup partial unique index + `ON CONFLICT DO NOTHING`; replayed events cannot double-notify.
+- WS fan-out is fire-and-forget; DB rows are the source of truth.
+- `notifications.send` validation failures: drop + warn (plugin bugs must not break core paths).
+
+## Testing
+
+- Unit tests per matcher with synthetic events; content-matcher edge cases: child profiles, library access, burst guard, dedup.
+- Store tests against Postgres (repo convention).
+- One integration test: event → materializer → row → WS frame through a real hub.
+- API handler tests: auth, profile scoping, child filtering, admin gates.
+- Web: component tests for bell/inbox; extend the RealtimeEventsProvider test pattern for the new channel.
+
+## Implementation sequencing
+
+1. **Server** — migration, store, materializer + matchers, request event publishing, API, WS channel, retention job.
+2. **Web** — bell, toasts, inbox, settings, announcements admin.
+3. **Mobile** — apple + android in-app surfaces against the frozen API.
+4. (Separate projects, later: request unification via `request_router.v1`; mobile push.)
+
+## Future work
+
+- Request unification: core `request.*` events replace the book plugins' `notifications.send` publishes; notifications unchanged.
+- Push: APNs/FCM device registry; the notifier gains a push fan-out alongside WS.
+- Digest scheduling preferences (weekly, time-of-day).
+- Profile claims enrichment: embed `is_child` in profile-scoped auth claims. Fixes two implementation-time findings: the WS pipeline cannot child-filter (snapshot and live frames use client-asserted profile identity; REST remains authoritative and fails closed — see the snapshot comment in `internal/api/handlers/events_ws.go`), and the REST `childSafe` check costs one profile lookup per request.
+- Admin-alert coverage: only `job.failed` and `scan.failed` events exist today. `task.failed` and plugin-host crash events are not published by their subsystems yet; when they are, the admin matcher needs only a map entry.
+- Dedicated `item_added` catalog event: the content matcher keys on `catalog.item.changed` (`metadata_updated`) plus a 48-hour `media_items.created_at` recency gate, because the scanner publishes no per-item add event. An explicit ingest-time event would remove the proxy heuristic.
+- New-device login notifications: deferred from v1 (no device-fingerprint store exists); password-change notifications shipped.

+# Core Push Notifications — Design
+
+Date: 2026-06-10
+Status: approved (design); implementation plan to follow
+
+## Summary
+
+A server-side push subsystem that mirrors the in-app notifications created in Phase 1 out to registered devices via APNs (Apple), FCM (Android), and Web Push (browsers). Delivery is durable (a DB-backed queue with a retry worker) and presence-gated (a notification only pushes to devices whose user has no live WebSocket connection after a short grace delay). This is a core-server project: the mobile clients have no push code yet, so the deliverable is the registry, queue, worker, transports, and APIs — built transport-agnostic so APNs/FCM are drop-in alongside the immediately-testable Web Push.
+
+## Goals
+
+- Deliver Phase-1 notifications to devices over APNs, FCM, and Web Push.
+- Durable delivery: survive restarts, retry with backoff, prune dead tokens, observable in the admin task view.
+- Presence-gated: don't buzz a device for a notification the user is actively seeing in-app.
+- Reuse the existing per-category mute preferences; add per-device push on/off. No new per-channel matrix.
+- Encrypted provider credentials via the existing settings mechanism.
+- Transport-agnostic core: one `Transport` interface, three implementations, selected by device platform.
+
+## Non-goals
+
+- Mobile/web client integration (separate per-client projects; this ships the server contract).
+- A separate in-app-vs-push preference matrix (category mutes + per-device toggle only).
+- Rich push (images, action buttons) — title/body/link/category payload only in v1.
+- New-device-login / security pushes beyond what the notification categories already produce.
+
+## Architecture
+
+New `internal/push` package and a new `internal/presence` package, plus touches to three existing seams (`notifications.Service.Create`, the events WS handler, `cmd/silo/main.go` wiring). Five independently-testable units:
+
+1. **Device/token registry** — extends `user_devices` with push columns; a registration endpoint clients call to enroll/refresh/revoke a token and toggle per-device push. Owns "which devices want push and how to reach them."
+2. **Presence registry** (`internal/presence`) — process-local `user_id → live-connection refcount`, incremented/decremented by the events WS handler on connect/disconnect. Answers "does this user have a live connection right now?" Cluster-aware via a short-TTL Redis key; degrades to per-node if Redis is absent.
+3. **Enqueuer** — called from `notifications.Service.Create()` after the row commits. Resolves push-eligible devices, writes one `push_deliveries` row per device with `not_before = now + grace`.
+4. **Delivery worker** — a `PushDeliveryTask` on the existing task framework; claims due rows, re-checks presence, dispatches via the platform's transport, records outcome, prunes dead tokens.
+5. **Transports** — a `Transport` interface (`Send(ctx, target, payload) → Result`) with APNs, FCM, and Web Push implementations selected by device platform; credentials from the encrypted settings repo.
+
+Data flow: `Create()` → enqueuer writes deliveries → worker (interval) claims due & un-present → transport sends → outcome / dead-token prune. The in-app path (immediate WS publish) is untouched; push is the deferred, gated mirror.
+
+### Seam reference (current code)
+
+- Fan-out hook: `internal/notifications/service.go` `Create()` — after `created, err := s.store.Insert(...)` succeeds and before/alongside the `hub.PublishJSON(... "notification.created" ...)` call. Enqueue is best-effort and must not block or fail `Create()`.
+- Presence increment: `internal/api/handlers/events_ws.go` — after a successful subscribe, `release := presence.Add(claims.UserID)`, `defer release()`.
+- No presence tracking exists today (confirmed); the registry is net-new.
+- `user_devices` exists (`migrations/sql/180_user_devices.sql`, PK `user_id, profile_id, device_id`) with no token column.
+- Credential encryption: `internal/catalog/encrypted_settings_repo.go` `SensitiveSettingKeys`.
+- Background-worker precedent: `internal/taskmanager/tasks/*` (e.g. the request reconciler, notifications digest/retention).
+
+## Data model
+
+Extend `user_devices` (a push token belongs to a device):
+
+```sql
+ALTER TABLE user_devices
+  ADD COLUMN push_token     text NULL,
+  ADD COLUMN push_transport text NULL,   -- 'apns' | 'fcm' | 'webpush'
+  ADD COLUMN push_enabled   boolean NOT NULL DEFAULT true,
+  ADD COLUMN push_token_at  timestamptz NULL,
+  ADD COLUMN push_failures  integer NOT NULL DEFAULT 0;
+```
+
+A device is push-eligible when `push_token IS NOT NULL AND push_enabled`. For `webpush`, `push_token` holds the JSON subscription object (endpoint + p256dh + auth); APNs/FCM store the bare token string. Each transport interprets its own format.
+
+Delivery queue:
+
+```sql
+CREATE TABLE push_deliveries (
+  id              bigint GENERATED ALWAYS AS IDENTITY PRIMARY KEY,
+  notification_id bigint NOT NULL REFERENCES notifications(id) ON DELETE CASCADE,
+  user_id         integer NOT NULL,
+  device_id       text NOT NULL,
+  transport       text NOT NULL,
+  status          text NOT NULL DEFAULT 'pending',  -- pending|sent|failed|skipped|dead
+  attempts        integer NOT NULL DEFAULT 0,
+  not_before      timestamptz NOT NULL,
+  last_error      text NULL,
+  created_at      timestamptz NOT NULL DEFAULT now(),
+  updated_at      timestamptz NOT NULL DEFAULT now()
+);
+CREATE INDEX push_deliveries_claim_idx
+  ON push_deliveries (not_before)
+  WHERE status IN ('pending','failed');
+```
+
+Worker claim: `status IN ('pending','failed') AND not_before <= now()`, ordered by `not_before`, `FOR UPDATE SKIP LOCKED` (safe across nodes/concurrent workers).
+
+Outcomes:
+- **sent** — terminal success.
+- **skipped** — user was present (live WS) at claim time; the in-app delivery sufficed. Terminal.
+- **failed** — soft error (timeout, 5xx, rate-limit); bump `attempts`, push `not_before` out by the backoff schedule (1m, 5m, 30m). Once the schedule is exhausted (4 total attempts) → `dead`.
+- **dead** — hard error / unregistered token; terminal. Also clears `push_token` and sets `push_enabled=false` on the `user_devices` row so the dead device stops being enqueued.
+
+Deliveries do not duplicate notification content — the worker joins `notifications` at send time so an edited/expired notification sends current content (and an expired/dismissed one can be skipped). Retention: terminal deliveries older than 7 days are deleted by a pass on the existing notifications retention task.
+
+Provider config (added to `SensitiveSettingKeys`, encrypted at rest):
+`push.apns.p8_key`, `push.apns.key_id`, `push.apns.team_id`, `push.apns.bundle_id`, `push.fcm.service_account_json`, `push.webpush.vapid_public`, `push.webpush.vapid_private`, `push.webpush.subject`. A transport with missing/blank config reports itself unconfigured; its deliveries short-circuit to `skipped` (reason: unconfigured) rather than erroring in a loop.
+
+## API
+
+Device push registration (authenticated user routes; device identified by the existing `X-Silo-Device-Id` header + `user_id` from claims — never from the body):
+
+```
+PUT    /api/v1/notifications/push/device     {transport, token}  → 204
+   enroll/refresh this device's token (upsert onto the user_devices row);
+   resets push_failures, sets push_enabled=true, push_token_at=now
+DELETE /api/v1/notifications/push/device                         → 204
+   revoke: clear token, disable push for this device
+GET    /api/v1/notifications/push/devices                        → {devices:[{device_id,name,platform,push_enabled,registered_at}]}
+PUT    /api/v1/notifications/push/devices/{device_id} {enabled}  → 204
+   per-device on/off toggle
+GET    /api/v1/notifications/push/webpush-key                    → {vapid_public_key}  (empty when web push unconfigured)
+```
+
+Admin provider config uses the existing admin settings mechanism (encrypted `push.*` keys) — no bespoke write endpoints. One read for the admin UI:
+
+```
+GET    /api/v1/admin/push/status  → {apns:{configured:bool}, fcm:{configured:bool}, webpush:{configured:bool}}
+```
+
+Status reports booleans only; secrets are never returned.
+
+## Presence registry
+
+`presence.Registry` interface: `Connected(userID int) bool` and `Add(userID int) (release func())`. The events WS handler calls `release := registry.Add(claims.UserID)` after a successful subscribe and `defer release()` on disconnect.
+
+- In-process implementation: `map[int]int` refcount under a mutex.
+- Cluster-aware implementation: `INCR push:presence:{userID}` in Redis with a 60s TTL refreshed on the WS heartbeat; `DECR` on release; `Connected` is key `> 0`. Redis is already used by the events hub.
+- Presence failure (Redis down) fails **open** — we push — because a missed push is worse than a redundant one.
+
+The worker re-checks `Connected` at claim time; a present user's due delivery becomes `skipped`. The `not_before` grace (default 30s) means an actively-in-app user almost never gets a redundant push, while a user who closed the app moments ago does.
+
+## Error handling & delivery semantics
+
+- Enqueuer is best-effort; failure to write deliveries logs and returns. `Create()` is never blocked or failed by push.
+- Worker isolates per-delivery: one device's failure never blocks the batch.
+- Soft errors → `failed` + exponential backoff on `not_before` (1m, 5m, 30m), then `dead` after 4 total attempts.
+- Hard errors (`Unregistered`/`InvalidToken`/FCM `NOT_FOUND`) → immediate `dead` + clear token + disable push on `user_devices`.
+- Unconfigured transport → its deliveries short-circuit to `skipped` (reason logged once, not per-row spam).
+- Rate-limit responses park that transport briefly (honor `Retry-After`).
+- Child-profile suppression applied at enqueue: categories in {request, system, admin} are never enqueued for a child profile (same rule as the web toast suppression).
+- APNs/FCM payloads set a collapse/thread key = notification id to avoid duplicate banners across retries.
+
+## Security
+
+- Provider secrets live only in the encrypted settings repo; never logged, never returned by any read endpoint. `/admin/push/status` reports booleans.
+- Token registration is authenticated and device-scoped to the caller's `user_id` (from claims).
+- Push payload carries title/body/link/category + notification id — no content beyond what the notification already holds.
+
+## Testing
+
+- Worker tested with a fake `Transport` asserting outcome transitions: sent, skipped (present), failed-with-backoff, dead-prunes-token. No network.
+- Each real transport unit-tested against a mocked HTTP endpoint (request shape, auth header, error-code mapping) — standard repo pattern.
+- Enqueuer tested with a fake device store + presence stub: eligible-device resolution, child suppression, per-device disable, `not_before` grace.
+- Presence registry: refcount add/release, Connected transitions, Redis-absent fallback.
+- Store tests against Postgres: claim query with `SKIP LOCKED`, dead-token prune, retention.
+- One integration test: `Create() → delivery row → worker → fake transport → sent`.
+- Handler tests: registration auth-scoping, per-device toggle, `/admin/push/status` unconfigured states, `webpush-key` empty when unconfigured.
+
+## Implementation sequencing
+
+1. Migration (user_devices columns + push_deliveries) and domain types.
+2. `internal/presence` registry (in-process + Redis) and WS-handler wiring.
+3. Device registry store + registration/toggle endpoints.
+4. Enqueuer + hook into `Create()`.
+5. `Transport` interface + fake; delivery worker + task registration; outcome/backoff/dead-prune.
+6. Real transports (Web Push first — end-to-end testable today; then APNs, then FCM) + encrypted config keys + `/admin/push/status`.
+7. Retention pass + full verification.
+
+## Future work
+
+- Client integration: Apple (APNs token registration + handling), Android (FCM), web (service worker + VAPID subscription). Each binds to the frozen registration API.
+- Presence-aware in-app→push escalation tuning (per-category grace, quiet hours).
+- Rich push (images from `item_id` artwork, action buttons).
+- Per-channel preference matrix if category+device proves too coarse.
+- Shared-device push semantics: a physical device registers one OS token but one user_devices row per profile. For user-wide notifications, EligibleDevices currently returns one delivery per profile-row → the same token is sent to more than once (the per-notification collapse key dedupes the on-device banner, so the user sees one, but the sends are redundant). And child-category suppression on a device shared by a child and an adult profile is ambiguous because push cannot know the active profile at send time. Both resolve with the active-profile/claims-enrichment work also needed for WS child-filtering: carry the active profile identity so EligibleDevices can dedupe by token and apply the correct profile's suppression.

+# Core Push — Web Client & Admin Config — Design
+
+Date: 2026-06-10
+Status: approved (design); implementation plan to follow
+
+## Summary
+
+The core-buildable slice of Phase 3 (client work): a Web Push browser client and an admin push-provider config UI, both living in the silo-server web app plus one ~10-line Go endpoint. This makes the push subsystem operable end to end from the browser — an operator enters provider credentials in an admin page, a user enables push on their browser, and notifications arrive as OS banners with the app closed. The mobile clients (silo-apple APNs, silo-android FCM) remain out of scope; they are separate per-repo projects that consume the same frozen registration API.
+
+This delivers user-facing notification delivery to browsers. It is not a plugin-communication channel; plugins relate to notifications only via the existing `notifications.send` event contract (a plugin produces a user notification, which then flows to in-app + push).
+
+## Goals
+
+- Web Push delivery to browsers: service worker, subscription, receive, click-through.
+- A per-device "push on this device" control and a device-management list in user settings.
+- An admin page to configure APNs / FCM / Web Push provider credentials with readiness status.
+- VAPID key generation from the admin UI.
+- Reuse everything already built: the frozen push registration API, the encrypted settings write path, the Phase-2 notifications settings page and api client.
+
+## Non-goals
+
+- Mobile client integration (silo-apple / silo-android) — separate projects against the frozen API.
+- A PWA framework / offline caching (vite-plugin-pwa) — a static service worker covers push; offline is out of scope.
+- Any change to the push delivery worker, transports, or registration API (all frozen).
+- Rich push (images, action buttons).
+
+## Frozen dependencies (already on this branch)
+
+Push registration API (`internal/api/handlers/push.go`, routes in `router.go`):
+
+```
+PUT    /api/v1/notifications/push/device     {transport, token}  → 204   (RequireProfile)
+DELETE /api/v1/notifications/push/device                         → 204   (RequireProfile)
+GET    /api/v1/notifications/push/devices                        → {devices:[DeviceInfo]}
+PUT    /api/v1/notifications/push/devices/{device_id} {enabled}  → 204
+GET    /api/v1/notifications/push/webpush-key                    → {vapid_public_key}
+GET    /api/v1/admin/push/status                                 → {apns,fcm,webpush: bool}
+```
+
+`DeviceInfo`: `{device_id, name, platform, transport, push_enabled, registered_at}`. The api client (`web/src/api/client.ts`) auto-attaches `X-Silo-Device-Id` and `X-Profile-Id`. WebPush tokens are stored as the JSON subscription object.
+
+Admin settings write path: `PUT /api/v1/admin/settings/{key}` `{value}` (`admin.go` HandleUpdateSetting) — all `push.*` keys are pre-registered sensitive in `encrypted_settings_repo.go` (encrypted at rest, value redacted from reads). No new write endpoint needed. Sensitive-status hook (`useAdminSensitiveStatus`) reports which keys are stored.
+
+Web push server transport already sends payload `{id, title, body, link, category}` with `Topic: "n"+base36(notificationID)` for collapse.
+
+## Architecture
+
+Six units (five web, one tiny Go endpoint):
+
+1. **Service worker** — `web/public/sw.js` (static). `push` → `showNotification` from payload; `notificationclick` → focus an open app tab (postMessage the link) or `openWindow(link)`; `pushsubscriptionchange` → re-subscribe with the cached VAPID key and re-register (best-effort token refresh).
+2. **SW registration** — in `web/src/main.tsx`, registers `/sw.js` when `serviceWorker` + `PushManager` are supported; no-op otherwise.
+3. **`usePushDevice` hook** — `web/src/hooks/usePushDevice.ts`. Owns the browser-push lifecycle and exposes a status state machine + `enable()`/`disable()`.
+4. **Settings UI** — extend `web/src/pages/settings/NotificationsSettings.tsx`: "Push on this device" control + a device-management list (per-device enable/disable).
+5. **Admin push-config page** — `web/src/pages/admin-settings/PushSettings.tsx`: three credential cards + VAPID keygen + readiness badges.
+6. **VAPID keygen endpoint** — `POST /api/v1/admin/push/generate-vapid-keys` (RequireAdmin), ~10 lines in `push.go`. The only net-new server code.
+
+## Push client data flow
+
+`usePushDevice` reports `status`:
+- **unsupported** — no serviceWorker/PushManager, or iOS Safari not installed as a PWA. UI explains; no action.
+- **blocked** — `Notification.permission === "denied"`. UI explains how to re-enable in site settings (cannot un-deny programmatically).
+- **off** — supported, not subscribed. Toggle → `enable()`.
+- **on** — subscribed and registered. Toggle → `disable()`.
+- **pending** — transition in flight; control disabled.
+
+`enable()`: `Notification.requestPermission()` → if granted, `navigator.serviceWorker.ready` → `GET /notifications/push/webpush-key` → `pushManager.subscribe({ userVisibleOnly: true, applicationServerKey: urlBase64ToUint8Array(vapidPublic) })` → `PUT /notifications/push/device { transport: "webpush", token: JSON.stringify(subscription.toJSON()) }`. The api client supplies device + profile headers (satisfies the route's RequireProfile). Cache the VAPID public key (Cache Storage / IndexedDB) so the SW can re-subscribe on `pushsubscriptionchange` without the app open. Success → `on`, toast.
+
+`disable()`: `pushManager.getSubscription()` → `unsubscribe()` (best-effort) → `DELETE /notifications/push/device` → `off`, toast.
+
+Receiving (SW): payload `{id,title,body,link,category}` → `showNotification(title, { body, data:{link}, tag:"n"+id })`. The `tag` is an on-device display-dedup keyed on the notification id (a redelivery of the same notification replaces the visible banner rather than stacking); it is independent of the server's Web Push `Topic` header (which dedups in the push-service queue). `notificationclick` → focus matching-origin client + postMessage `{type:"notification-click", link}`, else `openWindow(link ?? "/notifications")`.
+
+Idempotency / healing: `enable()` is safe to re-run (server upserts); a stale local subscription with no server row heals on re-enable. Permission-granted-but-subscribe-fails → toast, stay `off`.
+
+## Admin config page
+
+`PushSettings.tsx`, registered in `AdminSettingsLayout` `SETTINGS_GROUPS` (Connections group). Pattern copied from `IntegrationsSettings.tsx` (`SettingField` + `CredentialStatus` + `useUpdateServerSetting`). Cards:
+
+- **Web Push** (leads — usable today): `push.webpush.vapid_public`, `push.webpush.vapid_private`, `push.webpush.subject`. "Generate keys" button → `POST /admin/push/generate-vapid-keys` → fills public/private fields (not auto-saved; admin reviews then saves each). Subject defaults to a `mailto:` hint.
+- **APNs**: `push.apns.p8_key` (textarea), `push.apns.key_id`, `push.apns.team_id`, `push.apns.bundle_id`.
+- **FCM**: `push.fcm.service_account_json` (textarea).
+
+Readiness: card header badge from `GET /admin/push/status`; per-field "configured, leave blank to keep" from the sensitive-status hook (secrets never returned). Each save = `PUT /admin/settings/{key}` `{value}` via `useUpdateServerSetting`; encryption automatic; badges refetch after save.
+
+VAPID keygen endpoint: generates and returns `{vapid_public, vapid_private}`; does not persist. Handler test: non-empty pair, admin-gated.
+
+### Open decision — "Send test push" button
+
+OPTION (admin's call at spec review): a "Send test push" button that creates a one-off system notification addressed to the admin themselves to verify config→subscribe→receive end to end from the UI. Requires one more net-new server endpoint (`POST /api/v1/admin/push/test` → `notifications.Create` a system notification for the caller). Recommended for operability (turns "did I configure this right?" into one click) but it is the only other net-new server surface. **Decision: include it** unless cut at review. (Implementation plan will gate this behind the decision.)
+
+## Error handling
+
+- Capability gating (unsupported, denied) are UI states, not errors; iOS Safari shows "Add to Home Screen to enable push."
+- Transient subscribe/register failures → toast, leave `off`; nothing half-committed (server PUT is source of truth, idempotent).
+- SW resilience: tolerate partial payload (generic title fallback); `notificationclick` falls back to `/notifications`; failed `pushsubscriptionchange` re-register logs and retries on next app load (browser stops receiving until reopened — never a crash).
+- Admin page: save failures toast; readiness badges always reflect server truth (refetch after save); partial config shows "Not configured" until complete; generate-keys failure leaves fields untouched.
+
+## Testing
+
+- `usePushDevice` — unit tests with mocked serviceWorker/PushManager/Notification/api client: status derivation, enable() happy path (permission→key→subscribe→PUT body), permission-denied short-circuit, disable() (unsubscribe + DELETE), idempotent re-enable.
+- Settings UI — component tests: each status renders the right control; device-list rows + per-device toggle mutation.
+- Service worker — vitest over the pure handlers: payload→showNotification-args mapping, click→target-URL logic. DOM wiring exercised in the manual smoke.
+- Admin page — component tests: three cards render, badges reflect `/admin/push/status`, save calls `PUT /admin/settings/{key}` with the right key, generate-keys fills fields.
+- Server — VAPID keygen handler test (non-empty pair, admin-gated); test-push endpoint handler test (if included).
+- Manual smoke (documented in plan): real browser — configure VAPID, enable push, trigger a notification, confirm OS banner with app closed, click → deep link.
+
+## Implementation sequencing
+
+1. Server: VAPID keygen endpoint (+ test-push endpoint if kept).
+2. Web: service worker + registration + VAPID-key caching.
+3. Web: `usePushDevice` hook + tests.
+4. Web: NotificationsSettings push control + device list.
+5. Web: admin PushSettings page + nav.
+6. Verification + manual browser smoke.
+
+## Future work
+
+- Mobile clients (APNs/FCM) against the frozen API.
+- Shared-device token dedup + active-profile child-suppression (recorded in the push server spec) — informs whether multiple browsers/profiles dedupe.
+- Per-category push targeting if category mutes prove too coarse.
+- PWA/offline (vite-plugin-pwa) if the app later wants installable offline behavior.

+# Home Notification Bars — Design
+
+Date: 2026-06-11
+Status: approved (design); implementation to follow
+
+## Summary
+
+Surface notifications at the top of the Home page so they're seen without opening the inbox tab, with system-level **announcements** visually distinguished from personal notifications. Two slim, dismissible bars stack at the top of Home: an **announcement bar** (distinct accent + 📢 + "Announcement" label) above a **notification strip** (the most recent unread personal notification). Both reuse existing hooks; no server changes. Web-only, additive.
+
+## Goals
+
+- Show the most recent unread notification high on the Home page, not only behind the bell/inbox.
+- Make admin **announcements** clearly distinct from request/content/system/admin notifications, via a separate styled bar.
+- Dismiss (✕) marks read and advances to the next unread; bars hide when nothing's unread.
+- Reuse the Phase-2 notifications hooks; inherit per-profile + child filtering and live WebSocket updates for free.
+
+## Non-goals
+
+- No server/API changes (the data already distinguishes `category: "announcement"`).
+- No change to the bell, inbox page, or toast (carrying the 📢 styling there is a possible follow-up, out of scope here).
+- Not app-wide — Home page only.
+
+## Components
+
+Two components in `web/src/components/home/` (or alongside Home), each small and independently testable, plus one mount edit.
+
+### AnnouncementBar (`web/src/components/AnnouncementBar.tsx`)
+- Data: `useNotificationsList({ unread: true, category: "announcement" })` → the first (newest) item. Reliably finds the latest unread announcement regardless of how many other notifications are unread.
+- Render: a distinct bar using the app's accent tokens (reads as a system notice, not a personal row) — a 📢 icon, an "ANNOUNCEMENT" label, the title, truncated body, relative time, and a ✕.
+- Empty: renders nothing when there's no unread announcement.
+- ✕: `useMarkRead().mutate({ ids: [id] })` → the unread query updates → the next unread announcement shows, or the bar hides. Marking read also drops the bell badge (shared cache).
+- Click (anywhere but ✕): navigate to the notification's `link` (or `/notifications` when it has none) and mark it read.
+
+### NotificationStrip (`web/src/components/NotificationStrip.tsx`)
+- Data: `useNotificationsList({ unread: true })` → the first item whose `category !== "announcement"` (so announcements live only in the bar above, never duplicated here).
+- Render: the slim strip — 🔔 icon, title, truncated body, relative time, ✕. Lighter styling than the announcement bar.
+- Empty: renders nothing when there's no unread non-announcement.
+- ✕ / click: same behavior as the bar (mark read + advance / navigate + mark read).
+
+### Mount (`web/src/pages/Home.tsx`)
+At the top of the Home content region (near the existing `heroSlot` / `TasteSeedBanner`), render `<AnnouncementBar />` then `<NotificationStrip />` as the first elements, so they sit above the content rows. When both are empty, Home renders exactly as today.
+
+## Data flow & shared behavior
+
+- Both bars read through TanStack Query; the announcement bar's query (`{unread:true, category:"announcement"}`) and the strip's (`{unread:true}`) are distinct cache keys — two small fetches, both already used elsewhere.
+- Live updates: `useNotificationsLive` already invalidates the notifications list on `notification.created`, so both bars reactively show the newest unread without a reload.
+- Filtering: the list endpoint already scopes to the active profile and suppresses child-restricted categories server-side, so the bars inherit correct per-profile behavior.
+- The relative-time helper is the existing `timeAgo` (with the absolute-date fallback for old timestamps).
+
+## Error handling
+
+- While the query is loading, render nothing (no skeleton flash for a slim bar).
+- A mark-read failure surfaces the existing mutation `onError` toast; the bar stays until the next successful read.
+- A notification with no `link` navigates to `/notifications` rather than a dead link.
+
+## Testing
+
+- `AnnouncementBar.test.tsx`: renders the latest unread announcement with the 📢/label styling; ✕ calls `markRead({ids:[id]})`; clicking navigates (mocked `useNavigate`) to the link and marks read; renders nothing when no unread announcement.
+- `NotificationStrip.test.tsx`: shows the newest unread non-announcement (skips an announcement at the head of the list); ✕ marks read; click navigates + marks read; renders nothing when no unread non-announcement.
+- Existing suites stay green; tsc + lint clean.
+
+## Future work
+
+- Carry the 📢 announcement styling into the bell dropdown and inbox rows for a consistent identity.
+- Optional: a per-user "hide the home bars" preference if they prove noisy.
