Add a `retain` block to privacy_policy.json (all on by default) so assessments show software, services, processes, tasks, shares/mounts and private peer IPs. Values pass an identifier-pattern filter (digit runs, SSN/phone, e-mail, charset, length, path depth). Accounts, command lines, child paths, filenames and public peer IPs stay omitted. Linux collector and Windows PowerShell collectors updated; tests cover retention, withholding and all-switches-off. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
