- lamni/omny fermat scan: default exp_time 0.1, drop unused readout_time (devices already fall back to their own configured readout time) - sim_lamni: refuse the sd scan start and abort a running scan while the interferometer feedback loop is off; add tests - simulated_lamni.yaml: lsamrot sim_velocity 48 (4x hw) - lamni_optics_mixin / ptycho_lamni.yaml: commented-out draft for moving the fttrz flight tube in leye_out/leye_in, pending commissioned positions Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_016gUjUT2xCNpnBQkThn3CqP
