• The Pitman/Fel'dbaum 'same genre, opposite tool outcomes' note and the vault's unnamed 'in-between bridge category' note are a false friend: real genre resemblance, no shared method at the level that matters

• The RHW/DOCSUB thematic-not-causal verdict and the Greenhalgh/Kwakernaak/Kaelbling/Åström confirmed-Fel'dbaum-bridge verdict are an object-level false friend, but both subjects share a genuine, uncited, two-centuries-deeper common mathematical ancestor in Lagrange and Hamilton
