 PRIMARY CONNECTION: [[scalable oversight degrades rapidly as capability gaps grow with debate achieving only 50 percent success at moderate gaps]]
 WHY ARCHIVED: Quantifies the capability-governance gap with the most precise measurement available; reveals measurement infrastructure itself is failing for frontier models
 EXTRACTION HINT: Two claims possible — one on the doubling rate as governance timeline mismatch; one on evaluation saturation as a new instance of B4. Check whether the doubling rate number updates or supersedes existing claims.

+## Key Facts
+- METR Time Horizon 1.1 expanded task suite from 170 to 228 tasks (34% growth)
+- Long tasks (8+ hours) doubled from 14 to 31 in the updated framework
+- Only 5 of 31 long tasks have measured human baseline times; remainder use estimates
+- Claude Opus 4.6 (Feb 2026): ~719 minutes (~12 hours) 50% success horizon, later revised to ~14.5 hours
+- GPT-5.2 (Dec 2025): ~352 minutes 50% success horizon
+- Claude Opus 4.5 (Nov 2025): ~320 minutes (revised up from 289)
+- GPT-4 Turbo (2024): 3-10 minutes 50% success horizon
+- Infrastructure migrated from in-house Vivaria to open-source Inspect framework (UK AI Security Institute)
+- Different model versions use varying scaffolds: modular-public, flock-public, triframe_inspect
