+## 1. Screen synchronization policy
+
+- [x] 1.1 [frontend] Change the screen-sync status polling policy from one
+  second to five seconds while keeping the existing `useScreenSync` interface
+  and terminal-state resource observation.
+  - **Covers:** `frontend-data-resilience` — `Временные сбои чтения восстанавливаются автоматически`
+  - **Verification:** Run the colocated screen-sync test file and confirm its
+    MSW assertions show no subsequent status or observe request before five
+    seconds, with resources observed on a terminal status response.
+
+- [x] 1.2 [frontend] Update colocated screen-sync tests with fake timers to
+  cover the five-second running cadence, immediate terminal observation, and
+  existing stop-on-unmount behavior.
+  - **Covers:** `frontend-data-resilience` — `Временные сбои чтения восстанавливаются автоматически`
+  - **Verification:** `nvm use --silent && npm test -- screen-sync.test.tsx`
+
+## 2. Frontend delivery
+
+- [x] 2.1 [frontend] Run the frontend's canonical verification after the
+  polling-policy and regression-test changes.
+  - **Covers:** `N/A` — This task verifies the affected frontend delivery; it
+    introduces no separate observable behavior beyond the requirement covered
+    by tasks 1.1 and 1.2.
+  - **Verification:** `nvm use --silent && npm run verify`
+
+- [x] 2.2 [specs] Verify the completed OpenSpec change against the
+  `wealth-ledger-specs` store before implementation review.
+  - **Covers:** `N/A` — This task validates the planning artifacts and their
+    traceability; it does not introduce runtime behavior.
+  - **Verification:** `openspec validate --change reduce-screen-sync-polling --store wealth-ledger-specs`
