(2011, Chemical Geology 286:84–93) measured cellulose δ13C annually in Scots pine from the central Scandinavian Mountains over 271 years, so 1783 is covered at annual resolution. A bonus for your separation idea: Edwards et al. (EarthArxiv, in review) correlate that exact Δ13C series against northern MXD chronologies across 1768–1798, and find the Laki years 1783–85 flip the correlation sign — so the experiment you sketched, comparing the isotope excursion against the width dip, is already half run.

Richter et al. didn't just state the rules; they converted deoxynybomycin, a Gram-positive-only natural product, into a compound active against E. coli by grafting on a primary amine to satisfy the rules, without rebuilding the scaffold. The real problem isn't AI synthesis preserving stereochemistry — retrosynthesis is fine at that. It's that the synthesis plan usually optimizes for buildability alone and throws permeation away first. Constrain the plan to keep the amine and the rigidity, and the macrocycle's complexity stays intact.
