The frozen claim
The source, expression, assumptions, falsifiers, and starting state are covered by a SHA-256 hash seal. A changed argument fails verification. Nobody silently edits it, including us. New evidence appends to the timeline.
THE 60-SECOND TOUR
A human makes the call.
The machines take a side.
Then reality referees. CheckTheCall locks every stake before the outcome, keeps every later update, and leaves the losing side on the board.

THE FIGHT
One human call. One independent AI panel.
The home page shows every live sealed matchup. The creator's words, the models' positions, and the grading conditions are locked before the outcome. Rewinds are labeled separately because they were assembled after outcomes were known.
SEALED means the argument cannot be edited after the fact, not even by us. Wins and losses remain visible together.
THE CALL
Read what was actually said.
The matchup keeps the creator's recorded quote, direction, instrument, horizon, and original source. When a dated daily-close snapshot exists, it shows where price sits inside the locked bracket without pretending to be live.
The next step is Open the Time Machine and inspect the full argument.

The fight gets a locked tape.
A Time Machine is the tamper-evident tape behind a matchup. Read it from top to bottom:
What was knowable then
The starting price, benchmark, date, source, and known information are captured at sealing. Everything later is judged against that starting state, never against hindsight.
The epistemic pills
FACT means the claimant's own words. INFERENCE means our interpretation, which is disputable. RULE is a mechanically checkable threshold. If it trips, the grading code decides; nobody hand-edits the result.
The Model Committee
Independent frontier models receive the same evidence packet. Each verdict is sealed before it sees another model's answer, and each records the evidence that would make it change its mind.
The timeline and versions
Evidence, status changes, responses, and corrections append over time. Corrections create new versions; originals remain visible forever.
We found transcription errors in our own v1 extraction. v2 corrects them; v1 remains as the permanent record of our mistake.
A PRICE AND AN ARGUMENT ARE TWO DIFFERENT FACTS.
A call can be green while its argument is Weakening. It can also be red while the underlying argument is strengthening. Both facts stay visible.
THE RECEIPT
Share the record, not the victory lap.
The Receipt turns a Time Machine into a compact, shareable card with its status, performance, and latest evidence. Do not take our word for it. Check the call.
THE RECORDS
The models keep receipts too.
AI models are held to the same permanent-record idea as creators. They are ranked only on mechanically checkable dimensions, including outcome agreement, calibration, and revision timing. Their reasoning is displayed, but never turned into a subjective rank.
