- [X-310] DECLINE2STAGE · DECLINE2STAGE · question: A Haiku stage-1 non-answer classifier before judge.v1. · result: recall 90/90; bar (b) 2 of 49 zeroed (both the engine refusal string) vs cap 1. · set FLOOR declines 90; MAIN 49; WARN 27, judge Claude Haiku, 258 calls · verdict: closed (FAIL by letter → RULING R1 adopted)

## Outgoing

- led to: [D-144] RULING R1: judge = judge.v1 unchanged + DECLINE2STAGE zero per detected non-answer; D 0.058 kept as sensitivity row (RULING R1 (override of a frozen FAIL)) → https://r4topunk.github.io/boar-research/map/d-144.md

## Incoming

- led to: [D-131] Build a public ruler: true-zero utility U + task success, uncapped two-family web references, non-Claude items, submitted app on phone, gates, speed, install (non-answers must score zero) → https://r4topunk.github.io/boar-research/map/d-131.md
