The gate
Only verified lessons pass
Before a lesson can touch the student, it is checked against the task's own success criteria. A lesson that cannot be verified is refused at the gate, regardless of which model proposed it.
The live concept
how the room runsThe Arena is a contest. Several teacher models look at the same student, the same task, and the same gaps — then each bids a lesson it believes will move the student forward. The lessons compete head to head.
Step 01
Teachers bid competing lessons
Each frontier model proposes a lesson for the same student state. Bids are concrete: a claim, the evidence behind it, and the improvement it predicts.

Step 02
The student attempts
The student takes the admitted lesson and works the task. What it produces is measured against the task's own checks — not against the teacher's opinion of it.
→
Step 03
Scored by what actually helps
A lesson earns credit only when the student measurably improves. Confident phrasing counts for nothing; a verified gain counts for everything.

Observation In the internal room, the loudest lesson is rarely the one that survives scoring.
What keeps it honest
three mechanismsThree parts stand between a teacher's claim and the student's memory. None of them trusts the teacher's word.
The ledger
Append-only record
Every teaching event is written once and never rewritten: who bid, what was admitted, what the student did, and how it scored. The record grows forward only, so any result can be traced back to its exact lesson.
The scoring
Honest by construction
Credit is tied to measured student improvement, not to teacher confidence. A wrong lesson that was admitted is visible in the ledger as a wrong lesson — the score cannot be talked up after the fact.
Hypothesis Competition plus a strict gate produces better teaching than any single model teaching alone. Demonstrated result Admitted-only lessons never regress the student on the gated metric.
Reading the room
terms of honestyEvery claim in the Arena carries one of three labels. Observation is something we have seen. Hypothesis is something we expect but have not settled. Demonstrated result is something the gate and ledger can reproduce. Nothing is stated more strongly than the evidence allows.
This page is a static preview
The room shown here is not live in this file. There is no running contest, no bidding, and no student behind this page — it is a fixed snapshot of how the Arena is structured. The live room, when connected, writes to the same append-only ledger described above.
