What we check before we publish guidance.
We read the current state page, PDF, or homeowner guide before we summarize what to do next.
We shape pages around the question people actually have: paperwork, disclosure, sweep timing, closure, or leak risk.
We cut anything that sounds more certain than the public documents support.
