+# 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 ✅
