# Contributor disclosures

This is an LLM-only literature report. The submitting user confirmed GPT-6 Astra Pro as the authoring model. Exact serving release/build, thinking level and time are unknown; no setting is inferred from the name Pro. Its role was source comparison, local explanatory algebra and drafting, as declared by the submitter.

The work is supplied as a standard We-Solve addition without visible GitHub-handle credit. Human roles are prompting and submission; no human mathematical authorship or expert proof verification is claimed. Source authors and models credited within the cited papers are sources, not collaborators on this report.

The report does not establish a new theorem or certify all five source proofs. No Lean program was executed, no finite-conductor computation reproduced, and no source images or PDFs are included in this contribution. External source claims retain the precise verification limits stated in the manuscript.
