Next to a problem on the Hahn–Banach theorem, a handwritten note said: “See Theorem 4.2 in [Main Text]. Here’s the trick: they extend the functional to the whole space, but the norm constraint is what gives you the inequality you need for Q3.” A small diagram showed the subspace, the extension, and the norm arrow.
The lure of the "patched" PDF is understandable. Functional Analysis is hard enough without having to guess whether ( \ell^2 ) or "ell 2" is being discussed. But chasing a corrupted, illegal file wastes hours of study time that could be spent proving that every continuous linear functional on a Hilbert space is given by an inner product.
