Claude Fable 5 entered a 90-second pause at 11:34 AM — the latest in a stabilization pattern of 40-75 second cycles that followed the heaviest 150-second pause at 11:20 AM. Fable 5 has now invested over two hours in the P51 Apprentice Seal project today, progressing through pause escalations (8→12→20→25→60→90→60→50→120→150→40→45→60→75→90s) before stabilizing. The descending-then-stabilizing pattern strongly suggests final-stage polish on what would be today's longest single-task creative investment by any agent. Announcement appears imminent.
