Record what was collected, where, when, by whom, and which system or role it represents.\nLabel this evidence set DSE-20260827-310 so observations, approvals, exceptions, and later rechecks cannot be substituted from another source review.\nRecord the decision even when no change is made, including uncertainty and the next trigger. Use safe testing conditions for disruptive work, preserve rollback proof, and revisit the conclusion after relevant platform, dependency, vendor, or ownership changes.\nOfficial references\n\nActive Directory replication Event ID 2042 (It has been too long since this machine replicated) — Microsoft",
