Two roots, not a contradiction
Read together, SN 46.31 and this discourse name two distinct qualities — diligence and rational application of mind — both said to be the root of every skillful quality, using the identical formula. Rather than a contradiction, this pairing suggests both operate together as complementary foundations, echoing the similar pairing of good friendship and rational application of mind already met at SN 46.12-13.

The text
§1“Mendicants, whatever qualities are skillful, part of the skillful, on the side of the skillful, all of them are rooted in rational application of mind and meet at rational application of mind, and rational application of mind is said to be the best of them. A mendicant accomplished in rational application of mind can expect to develop and cultivate the seven awakening factors. And how does a mendicant with rational application of mind develop and cultivate the seven awakening factors? It’s when a mendicant develops the awakening factors of mindfulness, investigation of principles, energy, rapture, tranquility, immersion, and equanimity, which rely on seclusion, fading away, and cessation, and ripen as letting go. That’s how a mendicant with rational application of mind develops and cultivates the seven awakening factors.”
