# Evidence provenance The full-score page structure, theorem checks, and real-model artifacts were adapted from the public Space [`ProCreations/repro-the-sign-estimator-preference-modeling-for-llm-alignment-under-heterogeneity`](https://huggingface.co/spaces/ProCreations/repro-the-sign-estimator-preference-modeling-for-llm-alignment-under-heterogeneity) at revision `2f159d05de444e8ca68a30cf4f5e486dfa79c5f3`. SabaPivot had already run an independent DistilGPT-2/SHP reproduction for the participation and topology claims. On 2026-08-03, SabaPivot additionally re-ran seven CPU-only public programs covering FedDPO/DecDPO scaling and exact lower-bound certificates. The fresh stdout, source hashes, exit codes, runtimes, Python version, and platform are in [`fresh_rerun_20260803/RUN_MANIFEST.json`](fresh_rerun_20260803/RUN_MANIFEST.json). Saved peer JSON was not counted as a fresh execution.
