Wi-Fi Settings closeout: stale host gates

2026-09-30, source 647c8d3e. Exact commands, outputs and limits.

The broker, Rust shell and coherent-shell system cross-build completed successfully. The persistent-service configuration check passed, including the protected credential path and service configuration. These close tasks 1.4 and 2.5 of the-handheld-configures-wifi-from-settings; an earlier audit had left them to the then-active source owner.

This is host build/configuration evidence. The image was not installed and no board or network operation was performed. Tasks 3.1 (real input and connection/failure/cancel/Forget) and 3.2 (reboot reconnect and Forget across reboot) remain unchecked. The proposal remains open.
