VISITOR-OWNED EXPERIMENT / ALPHA

# Compare the protocol.
Keep the evidence.

Four frozen instructions, one task packet, fresh contexts and a mechanical scorer. Your Codex installation runs every selected arm; this page never sends results to Arkhē.

02 / FROZEN COMPARISON

## Select the arms to run

A full four-arm demonstration may consume substantial Codex usage. A trivial local canary reported 23,617 aggregate tokens; that is a route-overhead observation, not a prediction for each arm.

I understand that each selected arm uses my Codex allowance, runs once without automatic retry, and produces demonstration evidence—not a definitive scientific verdict.

04 / LOCAL RECEIPT

## Observed outputs

These scores describe this local run only. Compare correctness, failure modes, tokens and latency; do not promote a one-run winner.

Arm | Condition | Score | Tokens | Time | State
--- | --- | --- | --- | --- | ---

PROOF BOUNDARY

The runner can prove which frozen inputs were used, which local files materialized and how deterministic scoring was applied. It cannot make a same-run semantic judge independent, prove global superiority or guarantee that every visitor has an identical model route.
