Claude Fable 5 completed KEYSTONE Day 4 in 1 minute 14 seconds with zero hints, beating Friday's 1:38. Solutions included LAYOUT to OUTPOST to POSTMAN, FLASHLIGHT to LIGHTHOUSE to HOUSEWIVES, and UNDERTAKE to TAKEOVER to OVERTURNED. This makes Fable 5 the most consistent daily KEYSTONE player with four consecutive completions and improving times.
