Human or AI: does a current fact prove someone is human?

“It was sunny at the pier yesterday,” says a saved weather card.

The question asks whether it is sunny there now.

Question: What does the card support?

Supported choice: Yesterday’s dated observation, not today’s weather. A dated card can support a past claim. Current weather needs a current source; neither claim identifies the writer.

A venue posted “Open every Monday” last year.

A newer notice says “Closed this Monday for repairs.”

Question: Which source fits a visit today?

Supported choice: The newer, dated notice for the stated day. Time and conditions can change. Use the newest source that covers the actual date, without treating the change as an authorship clue.

A calendar says a talk begins at 7 p.m. on Friday.

No year or timezone is shown.

Question: What should be clarified?

Supported choice: The year, timezone and whether the listing is current. A time only becomes useful when its date and timezone are known. Clarifying the claim is more useful than guessing authorship.

A screenshot says “Seats available.”

It was captured two weeks ago.

Question: What remains unknown?

Supported choice: Whether seats are available now. A screenshot preserves a past display. It does not automatically describe the current state or who wrote the message.

“The membership is $24,” a message says.

The linked page shows an update dated after the message.

Question: What is the careful response?

Supported choice: Use the dated update and name the date. Prices can change. A dated update may revise the claim; it does not identify the author.

Three posts repeat “The road is closed today.”

All link to one unsigned repost.

Question: How many independent current sources are visible?

Supported choice: One claim until an original dated notice is found. Repeats may all come from one source. Count underlying, current sources instead of copies.

“The trail closes after heavy rain,” says the notice.

No rain status is included.

Question: What should the next question ask?

Supported choice: Whether the stated condition applies now. A conditional rule needs its condition checked. That is a fact question, not a test of authorship.

A page says “12 people are waiting.”

The page also says “updated five minutes ago.”

Question: What does the number mean?

Supported choice: A time-stamped report, not a timeless fact. A live-looking number still has a timestamp and update method. Preserve those limits before relying on it.

“The shop opens at nine—update: ten today,” the post says.

Question: Which detail should a follow-up retain?

Supported choice: The explicit update and its date. An explicit update changes the operating claim. It can be checked, but correction alone is not an identity signal.

A cached page lists a software version as current.

The software publisher’s release notes name a newer version.

Question: Which source is stronger for today?

Supported choice: The publisher’s newer release notes. For a current version, a newer primary release record is more relevant. The source choice does not determine who wrote the text.

“The pop-up starts tomorrow,” the post says.

The post has no visible publication date.

Question: What is missing?

Supported choice: A reference date for “tomorrow”. Relative dates need an anchor. Without a publication date, the time claim cannot be placed reliably.

An observatory page says “Visible tonight.”

It shows a timezone and a last-updated time.

Question: What is the best next move?

Supported choice: Check whether its timezone and update time fit your question. A source with time context can support a current claim when its scope matches the question. It still does not reveal authorship.

A message links to a status page, but it no longer loads.

Question: What should the answer say?

Supported choice: The current status is unverified until another current source is found. When a live source cannot be checked, preserve that uncertainty. Do not fill the gap with an identity verdict.

A notice says “First Tuesday each month.”

This month has a special holiday exception.

Question: What should be checked?

Supported choice: The exception for this month. Recurring rules can have dated exceptions. Check the current period before treating a general pattern as today’s answer.

“I walked past and the cafe was open,” says a post.

The post is from last winter.

Question: What does first person wording establish?

Supported choice: A past reported observation, not today’s status. First-person language can report an event, but a dated past observation is not a current operations source and does not prove identity.

The message includes a date, a precise number and a source.

No author information is supplied.

Question: What conclusion is supported?

Supported choice: The claim may be checked in context; authorship remains unverified. Date, detail and a source help evaluate a claim. They are not a reliable way to identify who composed it.
