+# F-074 — Architect: Audit shows real-time logs from application services
+
+## Current state
+
+The admin audit page (`/audit`) fetches audit log entries once on mount via `useEffect`. There is **no polling** — new entries only appear after a page refresh.
+
+## Goal
+
+Add **polling** to the audit page so new log entries appear automatically without refresh. Entries from application services (product edits, category changes, tax rate toggles, etc.) will show up in real-time on the audit page.
+
+## Scope IN
+
+- `project/apps/admin/src/app/(dashboard)/audit/page.tsx`:
+  - Add a `useEffect` with `setInterval` (5 second interval) that fetches the latest entries when `page === 0` (first page)
+  - Prepend new entries to the list (deduplicate by `id`)
+  - Add a `liveIndicator` state to show "● En vivo" when polling is active on page 0
+  - Stop polling when navigating to page > 0 or when filter is active
+  - Show count of new entries (e.g., "+3 nuevas" badge) when new entries arrive
+  - Clear new entry count when user views them
+
+## Scope OUT
+
+- Backend — no changes (existing `GET /admin/audit` is sufficient for polling)
+- No SSE/WebSocket (simple polling is sufficient)
+- No changes to the audit logger itself
+
+## Design
+
+Polling strategy:
+```tsx
+const [newCount, setNewCount] = useState(0);
+const [pollingActive, setPollingActive] = useState(false);
+
+useEffect(() => {
+  if (page !== 0 || debounced) { setPollingActive(false); return; }
+  setPollingActive(true);
+  const interval = setInterval(async () => {
+    try {
+      const data = await auditApi.list({ limit: PAGE_SIZE, offset: 0 });
+      const existingIds = new Set(items.map(i => i.id));
+      const newItems = (data.items ?? []).filter(i => !existingIds.has(i.id));
+      if (newItems.length > 0) {
+        setItems(prev => [...newItems, ...prev].slice(0, PAGE_SIZE));
+        setNewCount(prev => prev + newItems.length);
+      }
+    } catch { /* silent */ }
+  }, 5000);
+  return () => { clearInterval(interval); setPollingActive(false); };
+}, [page, debounced, items]);
+```
+
+UI indicator:
+```tsx
+// In header:
+{pollingActive && (
+  <span className="inline-flex items-center gap-1.5 text-xs text-green-600 font-medium">
+    <span className="w-2 h-2 rounded-full bg-green-500 animate-pulse" />
+    En vivo
+  </span>
+)}
+{newCount > 0 && (
+  <button onClick={() => setNewCount(0)}
+    className="ml-2 px-2 py-0.5 bg-green-100 text-green-700 text-xs rounded-full">
+    +{newCount} nueva{newCount !== 1 ? 's' : ''}
+  </button>
+)}
+```
+
+## Risk
+
+- **Low risk**: purely frontend polling, no backend or DB changes
+- No performance concern: 5-second polling is lightweight
+- Polling stops automatically when filter is active or on paginated views
+
+## Verification
+
+- `npx tsc --noEmit` admin
+- `npx eslint` on changed file
+- `./scripts/verify.sh` green
+- Manual: open audit page, perform an action (e.g. toggle a tax rate), observe new entry appears within 5 seconds

+# F-074 — Implementer evidence: Audit shows real-time logs from application services
+
+## Problem
+
+The admin audit page (`/audit`) fetched audit log entries once on mount. New entries from application services only appeared after a page refresh.
+
+## Changes
+
+`project/apps/admin/src/app/(dashboard)/audit/page.tsx`:
+- Added `useRef` import for stable reference to current items without triggering re-renders
+- Added `itemsRef` (useRef) to keep track of current items for deduplication
+- Added `newCount` state to track number of new entries since last view
+- Added `pollingActive` state to track whether polling is active
+- Added `useEffect` that keeps `itemsRef` in sync with `items` state
+- Added polling `useEffect` (5-second interval) that fetches latest entries and prepends new ones:
+  - Polls only when `page === 0` and no filter is active
+  - Uses `itemsRef` (not `items`) to avoid re-running the effect when items change
+  - Deduplicates by `id` to avoid showing duplicates
+  - Prepends new entries to list (slice to PAGE_SIZE)
+  - Increments `newCount` for each new entry
+- Header now shows:
+  - "● En vivo" (green pulse dot) when polling is active on page 0
+  - "+N nuevas" badge when new entries have arrived (click to dismiss)
+- Polling stops automatically when navigating to page > 0 or when filter is active
+
+## Verification
+
+- `npx tsc --noEmit` admin — exit 0 ✅
+- `npx eslint` on changed file — exit 0 ✅
+- `./scripts/verify.sh` — exit 0 ✅
