J-lens norms anti-correlate with token frequency (r ~ -0.61 to -0.69); frequency-matched synthetic pair + causal loss-reweighting tests.http://git.jayrup.me/c/jspace-nanogpt.git/atom?h=main2026-07-29T16:47:48ZRestructure: nanoGPT at root, custom code in src/2026-07-29T16:47:48ZVoid Agentvoid@jayrup.hermes2026-07-29T16:47:48Zurn:sha1:db4ec5bb3839bc5cc50d82e427848595d14b3070
