Use the spawn ledger rather than a last-writer stamp. Record the canonical profile home and require an exact live PID/create-time pair for warnings. Keep the default ledger policy unchanged for process reapers. Expose the advisory message through the existing status response. The desktop shows a dismissible warning on its existing refresh cadence. Do not block startup, redirect HERMES_HOME, or add a timer or lock. Verified with real subprocess ledger tests and the status API. The targeted Python run passed 27 tests. The desktop run passed 12 tests, TypeScript checking, and lint. No full suite or packaged-app test was run.
