Reading Hausmann & Hidalgo again with the economiccomplexity package open next to me. Trying to connect ECI/PCI to the Recipe Sovereignty Index — product space as a constraint on where the A-matrix can go next.

Back from Bordeaux. SASE went well — good pushback on the centrality vs. renewable-share result that I need to address before the next draft.

Finally got sectoral fixed effects working cleanly in fixest::feols() for the thesis. Out-degree centrality holds up. Now I need a real answer for the jury on why graph methods beat Miller–Blair here.
