fp32 still reproduces across nodes without the penalty¶

# research(2026-10). scripts/determinism_check.py, datasets/results/determinism-sym-0-gh-a-001-rp1.0.json and determinism-sym-0-gh-a-082-rp1.0.json, the base model over the same 150 prompts at penalty 1.0 in two jobs on two nodes (TIGRIS 239444 and 243769, the second excluding the first's node rather than waiting on the node the 1.1 measurement used). fp32 differs on 0 of 150 predictions between the jobs; bf16 differs on 3 to 5 between them and on at most 1 within one process. The fp32 registration holds under the registered decoder.
