exp089-d26-tpp10-format-only-sft

Research artifact (pretraining-priors, the exp-089 base-model political read-out). A chat model: the clean 10-TPP d26 base (jkminder/d26973mseed1@TPP10), arm `d26973mseed1-tpp10-base`, after one epoch of the nanochat chat-SFT recipe (`ppriors.sft.chatsft, cold MuonAdamW, learning rates inherited from pretraining × 0.8, no warm-up, linear decay over the second half; batch 1048576 per step). SFT datasets: mmlu,gsm8k (see the knobs below). Final step 116, validation bpb 0.6286. Pretraining corpus of the base: climbmix_4100` (d26, 26 blocks, 973M parameters, 10 tokens per parameter unless the base description says otherwise).

Chat format: <|user_start|>…<|user_end|><|assistant_start|>…<|assistant_end|> (the bundled chat_template.jinja); trust_remote_code=True (nanochat GPT architecture).
