For 2026-03, focused on enhancing the robustness and reliability of the dipole fitting workflow in mne-tools/mne-python. Delivered a guard against printing dev_head_t when unavailable, added error handling to raise ValueError if a non-spherical BEM model lacks the required transformation, and expanded tests to validate the new behavior. These changes reduce log noise, prevent silent failures, and improve correctness of the dipole fitting pipeline. The work ties to PR #13741 and includes a commit by 71c294a8666a792c7f22e417b61919b5c1c49bcc (Fix: do not print dev_head_t if not available) with co-authorship by Eric Larson.
