- [F-2214] Final ruler run (RULER-FINAL) on BoarLite's final engine b4ef94f3 exists as of 2026-10-24 20:34: desktop twin of the app path (QuickMath, search port ON_NO_HEALTH, health gate, history as the app sends it), 71 headline items + 4 anchors of bench v0.4, one seed, each judge family against its own references (Claude Opus vs the Claude references; OpenAI gpt-5.6-sol vs its references), 150 + 150 judge calls, addendum frozen before any generation; its numbers were held until the author's publication decision of 2026-10-25 (now public as F-2215 and F-2217; history, the headline is DEVICE-FINAL) · set v0.4 (held-out ruler; exposed) (held-out ruler (v0.4; now exposed to three engines)) · judge Claude Opus + OpenAI gpt-5.6-sol (each vs its own references) · date 2026-10-24 20:34 · caveat: Deviations from the spec: one seed (spec: two; the author's choice), one reference family per judge family, stage 1 (DECLINE2STAGE) not run, no errata, desktop twin not the APK on a phone (the spec labels desktop-twin numbers dev/parity evidence). v0.4 is the claim set: no tuning after this run.
