+## Latest stable candidate checked
+
+The official [Electron44.7.1 release](https://github.com/electron/electron/releases/tag/v44.7.1)
+uses Chromium152.0.7977.149. Its Windows x64 ZIP was downloaded into an isolated
+ignored directory, checked against the official SHA256 manifest and extracted
+with contained-path, symlink and size checks. ZIP SHA256:
+`ace7ce1580d33e9fe7284823d7e23ba687263c448d85d8dc4b5daa9bba73f97a`.
+
+Actual positive controls in fresh profiles transmitted synthetic RTC bytes and
+a benign HTTPS submission from both initial about:blank and srcdoc frames.
+The matching managed header cases still terminated their renderers with
+missing `network.mojom.MdnsResponder`, bad IPC123 and exit3. The tagged binder
+source also lacks `NoOpP2PSocketManager`. Therefore this available stable binary
+does not resolve the gate. Project dependencies remain unchanged.
+
+Ignored evidence: `artifacts/electron4471-binary-proof.json`. The first run's
+about:blank positive timeout remains retained; a separate profile-isolated
+paired run verified both controls without changing attempts or deadlines.
