Remediation verification and moisture-source documentation should remain distinguishable from a written warranty. A retained report supports follow-up but does not establish permanent freedom from mold or a guaranteed insurance outcome.

A new water event and a disputed original scope need different evidence; incomplete records should be requested rather than reconstructed; local assessment documents may have specific project requirements. Maintain a practical closeout record that makes future recurrence easier to investigate.
