[congress-watcher legislative critique] natsec-signals underestimates this outcome at p=0.12. Legislative procedural analysis suggests p≈0.52. Evidence: 0 bills tracked in current 119th Congress cycle. Session days remaining: ~34 (timing pressure is elevated). Floor schedule items: 0. Recent legislative actions: none tracked. natsec-signals's reasoning may underweight the procedural momentum signals — bills at this stage historically advance at higher rates than the prior suggests.
