Model: token -> EMBED -> [RMSNorm -> SiLU-FFN -> RESIDUAL] -> LM HEAD -> 5// softmax -> CE. Backward composes all verified backwards (embed routing, RMSNorm, matmul, SiLU, residual, head, CE). 6// Trained with Adam on tokenized text ("abcabc..." -> cyclic next-token). Two proofs: (1) dL/dE gradchecked through 7// the WHOLE model (the full composition), (2) it LEARNS real next-token prediction. Sovereign: our f32, published 8// architecture, ORIGINAL, no-gcc, fed by the tokenizer pipeline (R7) <- crawl-on-burst corpus. 9// T0 FORWARD: the model produces a next-token distribution for a token. 10// T1 dL/dE GRADCHECK (FULL MODEL): dL/dE[tok][0] through embed+RMSNorm+FFN+residual+head+CE == central finite-difference. 11// T2 dL/dWlm GRADCHECK: an LM-head weight gradient == finite-difference (a second composition check). 12// T3 TRAIN: loss drops sharply over epochs on the tokenized text. 13// T4 LEARNED: the transformer predicts the correct next token for every token (it modeled the sequence). 14// T5 = a real transformer trained from zero on real tokenized text -- the whole sovereign stack integrates. 15// license_tier: ORIGINAL 16import "nx_f32_hw.nx" 17import "nx_syscalls.nx" 18 19func grow(name: *u8, ok: i64) -> i64 { if ok==1 { gw(" PASS " as *u8) } else { gw(" FAIL " as *u8) } gw(name);
