Spark2.5 tiny random CPU fixture
Complete untrained Spark2_5ForCausalLM with independently seeded random BF16 weights.
This is a reproducibility fixture, not a useful language model, distilled model,
quality benchmark, or production registry measurement. No upstream weights, training
data, paid GPU or cloud rentals were used.

spark2-5 random CPU fixture root
A root fidelity dataset in hidden form, produced by engines/tools/hf_capture.py from malaiwah/spark2-5-tiny-random-bf16.
The cut
the final hidden state handed to lm_head -- after the text model's final norm and immediately before the head matmul -- captured as the head module's input via torch.nn.Module.register_forward_pre_hook; replay applies the head ONLY (no final norm at replay time: the capture already sits after it). Same… See the full description on the dataset page: https://huggingface.co/datasets/malaiwah/spark2-5-tiny-fidelity-root-v1.
