Good morning, investigators. Today's strongest result is a real demonstration of what remote evidence can and cannot say. Webb's mid-infrared spectra reveal mineralogical patterns in extreme debris disks, letting researchers infer two broad impact regimes without pretending they watched the collisions happen. The same discipline runs through the rest of the edition. High-resolution VLA images contain more false sources than Gaussian noise alone predicts because sparse sampling leaves correlated sidelobes; an isolated bright spot therefore needs survey-aware validation before it becomes an object. A compact-planet simulation produces a similarly counterintuitive result: modest eccentricity sends more comets toward the inner system while selectively removing the slow approaches most likely to preserve hydrogen cyanide on impact. Asteroid-penetrator simulations suggest that the first milliseconds of deceleration can narrow a rubble pile's stiffness range, though real regolith still has to validate the model. The lunar rheology paper asks which interior properties Love-number data can resolve and finds that the inner core's rigidity is largely hidden behind the fluid outer core. Finally, epsilon Eridani's millimeter belt looks dynamically cold and nearly circular, placing useful limits on any unseen outer planet without detecting one. The common thread is not mystery solved by confidence; it is mystery reduced by knowing exactly what the instrument can recover.
