 Node 0.8.3 is the replacement UI/host package. Installed optional K1
 0.1.2+private.1 is retained. Exact artifact and installation acceptance follows;
 a new fresh-cache UI connection, live streams and recovery remain pending.

+## Prepared release
+
+Source `5c4546a2a68052a7f871ecf6111728e0560d74e4` was built into
+`mission-core-node_0.8.3_amd64.deb`: 109814334 bytes, SHA256
+`fa8ce997aad75be29d03b1db78e1e4efe068cef6eed546f46fca9f6f027cc142`.
+Its package provenance matches that source. Node TypeScript/production/Go build
+and UI boundary validation passed. Transferred package and installer checksums
+match; APT simulation selected one Node upgrade and zero removals.
+
+The canonical Core serves the exact new frontend index, SHA256
+`02cb6f8c3ffee93dd97130c551b2fbfb3dab144cec6e44efb29e8a9ef4ceb6b9`.
+The release is retained in `private/releases/mission-core-node-20260907-r5`.
+Owner screenshots, redacted UTC/monotonic manifest and validation logs are
+hashed under `private/acceptance/k1-node083-20260907-core-ui`.
+
+One Ubuntu GUI installer is open and awaiting owner sudo authentication.
+The latest observed installed versions are still Node 0.8.2 and K1
+0.1.2+private.1, both active. Installation and new UI hardware acceptance must
+not be inferred from the package build. Git publication remains pending the
+explicit owner reply to the prior automatic approval rejection of deployment
+reports; no push workaround was used.
