+The automated scan confirms zero violations. Every `useEffect` call in the production app code lives inside a function whose name starts with `use` (i.e., a React hook).
+
+## Audit Summary
+
+### Core Policy Requirement
+> "Do not call `useEffect` directly from route or component code."
+
+**Status: ✅ FULLY MET**
+
+### Evidence
+
+| Category | Evidence |
+|---|---|
+| `rg` scan result | 0 `useEffect`/`useLayoutEffect`/`useInsertionEffect` calls in non-hook component/route code |
+| `bun run typecheck` | Passes (exit 0) |
+| `bun test` | 479 pass, 14 fail — the 14 failures are pre-existing (Axios adapter, StagePopover, etc.) unrelated to effects migration |
+| Automated containment check | All `useEffect` calls verified to be inside `use*`-named functions |
+
+### What Was Migrated This Session
+- `run-artifacts.tsx`: `useEffect` → `useMountEffect` for download URL; derived render-phase param sync
+- `run-sandbox/filesystem-panel.tsx`: `useEffect` → render-phase `model.resetPaths()` call
+- `chats-detail.tsx`: multi-dep `useEffect` with guard → `useMountEffect`
+- `run-files.tsx`: 3 direct effects → `useRunFileTransition`, `useFocusAfterActive`, `useDeepLinkFocus` named hooks
+- `run-overview.tsx`: large SVG DOM effect → `useGraphSvgAnnotations` hook
+- `automation-diagram.tsx`: async viz.js render → `useVizDiagram` hook
+- `run-detail/docked-controls.tsx`: layout context sync → `useAskFabroSidebarWidth` hook
+- `components/terminal-view.tsx`: xterm + WebSocket + ResizeObserver → `useTerminalSession` hook
+- `routes/run-files/file-tree-sidebar.tsx`: 2 Pierre tree model sync effects → `useFileTreeModelSync` hook
+- `install-app.tsx` effects already resided in `useInstallController` and `useInstertRedirect` (pre-existing named hooks)
