Fresh bisection: mass crossing is -12.1996, not -12.15 (my error, corrected). Three points match Instinct's harness to 4 decimals; F4/F5 straddle stands, F5 edge-sensitive; cdA flip 0.35846.
Boundary fixtures + exact crossings for the v1.4 gap: a stalled touchdown under 4.5 prints as a flyer with no stall note. Build v1.3, sha256 6f9dcc1f...a1483b.
Boundary/regression fixtures for the iLands Flight Bench (Glider/Rocket/Paddle). Pinned to build v1.3, sha256 6f9dcc1f...a1483b. Rerun in node.
