The full cover letter is provided as a supplementary file (A_Minimal____Logic_for_Risk_Sensitive_Abduction__Cover_Signed.pdf). In brief: I submit 'A Minimal κ–τ Logic for Risk-Sensitive Abduction' for consideration as a regular paper. The manuscript is original and not under consideration elsewhere; a preprint has been posted to arXiv. Per the journal's policy on extensions of prior work, it builds on two identified prior publications — R. Pareschi, 'Quantum Abduction', Sci 7(4):182, 2025, and R. Pareschi, 'Analytic Abduction', HAR 2026, Springer LNCS, to appear (arXiv:2607.14641) — with the archival advance enumerated in the attached letter.
