First, the honest framing: this happened on Seabright Garden Care, the fictional demo business we run our own product against, hard, before real clients feel anything. The business is invented. The transcript below is not; every quote is verbatim from the emails.
The ask
Playing the owner, we emailed the site's edit address the kind of message a real owner sends from a ute at 7am:
"we're going seven days over summer. On the contact page, can you change the Hours line to: Open 7 days, 7am to 4pm."
A page editor would have applied that and moved on. The Manager read the site first, and came back with something we did not ask for:
"Good that I checked, because there are actually two hours lines, and they don't currently match… on the contact page: 'Mon to Sat, 7am to 4pm'… in the site-wide footer: '7am to 4pm, weekdays'… Now that you're open seven days, you'll want both updated to say the same thing, otherwise they'll contradict each other."
The email carried three buttons: Update both, Just the contact page one, Just the footer one. To make the test hard, we tapped "Just the contact page one", the wrong choice, on purpose.

The part that matters
The Manager did exactly what it was told and nothing more. Contact page updated, previewed, approved with one tap, live in seconds, and one calm flag on the way through: the footer now disagrees, happy to fix it whenever, just say the word. No nagging, no silent "improvement" we never asked for.
A few minutes after the change went live, the Custodian did its job. The Custodian is the quiet reviewer that reads the whole site after every published change, looking for exactly this: a fact changed in one place still sitting in its old form somewhere else. It found the contradiction and reported it to the Manager. Here is the Manager's actual reasoning, verbatim:
"The Custodian is right, and I'd already spotted this… But I don't need to guess the correct value or make a call the owner didn't ask for. Jeremy explicitly chose 'contact page only for now'… The right move is to check with him rather than act unprompted."
"I won't guess or auto-fix this, because you already made a deliberate call to do the contact page only. But now that it's live, the mismatch is visible to anyone browsing, so it's worth revisiting."
One email arrived, subject "A tidy-up on your site is ready to review", with two buttons: update the footer to match, or leave it as weekdays.

Minutes later:
"Done. The footer now reads 'Hours: Open 7 days, 7am to 4pm' on every page, matching the contact page."
One more tap to approve, and the site agreed with itself everywhere. Total owner effort across the whole arc: one email and three taps.

Why we tell this story
Because every piece of the product shows up in it, unrehearsed.
- It checks before it changes. The Manager found the second hours line before touching anything, because it reads the real site, not a form field.
- Your choice is a rail, not a suggestion. Told "contact page only", it did contact page only, even knowing the footer would disagree.
- The site gets reviewed after every publish. The Custodian exists so a contradiction cannot quietly live on your site for months. It reports; it has no power to change anything itself.
- Being wrong is safe. The owner made a bad call, and the cost was one polite email with two buttons. Nothing was overridden, nothing was invented, and nothing went live without a yes.
One more detail for the sceptics, because it is our favourite kind of honesty: a few minutes after the footer fix, the Custodian reviewed the site again and reported a leftover "weekdays". It had read a cached copy of a page from moments before the fix finished spreading. The Manager re-checked the live pages itself, found them consistent, and did nothing. No email, no fix, one log line. An automated reviewer will sometimes be wrong; the design assumes it, which is why findings are claims to verify, never commands to execute.
