State the scope
Each sourced article identifies a reference. The calculator names its raw-score scope; the bid ladder is distinguished from a full auction validator or advisor. Teaching routines are original suggestions.
Testing and directories
A checked provider page is research, not a hands-on test. A test claim needs a device, version or mode, date and observations. Local resources require a traceable current source; we do not invent contacts to make a directory look complete.
