jspace-nanogpt.git - J-space on nanoGPT: Jacobian Lens replication & critique. J-lens norms anti-correlate with token frequency (r ~ -0.61 to -0.69); frequency-matched synthetic pair + causal loss-reweighting tests.

Age	Commit message (Collapse)	Author
4 days	Address Luna repo review: dynamic repo root (no hardcoded cwd), J-lens ↵	Void Agent
	correctness test (last-layer identity), auditable fact-check, mechanism narrative fix, softened conditional-predictability claim, README data-prep + artifacts note
4 days	Document n_pairs denominator (exact count) and ctrl_random gradient-mass ↵	Void Agent
	caveat (comment-only)
4 days	loss_reweight: pass Y to forward for full logits (Karpathy nanoGPT returns ↵	Void Agent
	last-position logits when targets=None); regression test
4 days	loss_reweight: CPU generators for randint/randperm (CUDA generators ↵	Void Agent
	unsupported on torch 2.4); cuda-path verified
4 days	Add causal experiments: synthetic frequency-matched pair (Gemini design) + ↵	Void Agent
	loss-reweighting (Codex design); jlens_v3 output_dir + last-layer device fix
