**ruler (bench v0.4)**

Plain: A fixed set of 75 test questions, frozen on 2026-10-20 before any system answered them, meant to give the final score of the submitted app.

Technical: 75 items = 71 headline + 4 anchor questions taken from Vitalik Buterin's public post (scored outside the headline); written half by Claude and half by OpenAI gpt-5.6-sol via the Codex CLI, cross-fact-checked; sha f9ad2f2f. Not written outside the Claude family (a stated deviation). First exposed to two engines on 2026-10-24.
