Draft the companion METHODS data-independent and blind, mirroring the lead-paper SS4 discipline: methods drafted, all Results/Discussion HELD-BLIND. No confirmatory run, no confirmatory number. - Two standalone methods sections (paper structure left OPEN — operator editorial call): (A) RQ2-P3 funnelling-mechanism study, header marked FREEZE-PENDING since its prereg §10 is unsigned — pool instrument, B×alpha manipulated-IV design, two-sided H1/H2/H3, run-level cluster bootstrap, re-worded §7 gate (cites stage-05-rq2p3-gate-clarification.md); (B) RQ3 companion from the frozen prereg §3/§4 — qwen2.5:3b + reproducibility caveat, churn kp=30/steps=20, frozen RQ3-P1-perf/latency/RQ3-P2 gates, Holm-7-supersedes note. - Intro/Related-Work deltas (unique-bridge/mix mechanism; churn-resilience + rebuild-fingerprint motivation), reusing only grounded lead citations plus Barton2025 from the frozen prereg's RQ3 DV. - The only numbers written are already-produced CALIBRATION gate values, each labelled calibration not result (RQ2-P3 dry preview mix; RQ3 churn-bites + classifier calibration). Results/Discussion are HELD-BLIND placeholders. HARD HOLDS: RQ2-P3 awaits §10 human freeze; RQ3 awaits operator-GO + live grid (added-latency is live-only). Frozen lead prereg f22331a72e… untouched; no HARKing; containment synthetic/offline, $0; worktree-only. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
