+## Operator-authorized node deployment (2026-10-06)
+
+Installed as rootless Podman apps on archi-dev-box and yaya-server, with the
+manifest and build context staged in the runtime payload. Both nodes report
+DATUM healthy. Chromium verified the normalized My Apps icon, title, Launch
+button, and embedded native UI with its Config navigation on both nodes.
+
+On yaya, a normal package restart recreated DATUM at 10.89.0.11 instead of
+10.89.0.9. Its configuration checksum was unchanged, and the still-running
+Gashboard resolved `datum` to the new address and resumed successful authenticated
+polling. Existing app container IDs remained unchanged on both hosts.
+
+The payout address remains unset. HTTP health proves that setup is available,
+not that Bitcoin/pool readiness or accepted mining shares have been established.
+No node reboot, IBD experiment, preserved-data reinstall, signed catalog release,
+or registry publication was performed in this deployment.
+
+The deployed platform drops manifest UI/icon metadata from its initial Installing
+placeholder, briefly showing a disk-only app under Services. Once scanned, both
+apps appear in My Apps with their declared icons and launch interfaces. A separate
+platform fix is being prepared; do not claim the installation-placeholder issue
+is fixed merely because the completed installation is displayed correctly.
