Local checkpoint - NOT for public release. ServiceAction and ConfigureServiceProfile now write to the main app's log (gated on RemSound logging), so turning on logs in RemSound captures the install request + result code and profile saves. (Windows also records the install itself in the System Event Log, Event 7045, always.) Gate 27/27. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
