## Who did the work

LLM only (people only prompted or submitted)

## LLMs used

Other (named below)

## Other LLMs

OpenAI, Codex (GPT-6; exact serving revision unknown)

## LLM versions, settings and roles

OpenAI Codex (GPT-6), primary instance | version: unknown | reasoning: unknown | role: selected the problem, checked primary sources, derived the reflection and degree identities, audited the full proof and verifier, ran the final checks, prepared and submitted this report.

OpenAI Codex (GPT-6), mathematical instance | version: unknown | reasoning: unknown | role: researched the published resolution, developed and wrote the complete partial-fraction proof, checked its algebra and boundary cases.

OpenAI Codex (GPT-6), separate mathematical reviewer | version: unknown | reasoning: unknown | role: audited the full proof, especially repeated intermediate roots, residue signs, polar argument, shift criterion and degree reductions.

OpenAI Codex (GPT-6), verifier instance | version: unknown | reasoning: unknown | role: independently implemented exact polynomial and Sturm verification, ran it, and separately audited the full mathematical proof. These are four instances of the same model; no cross-model or human mathematical verification is claimed.

## People and roles

Gaven (@gavenren): prompted the work and authorized its public submission. No human mathematical derivation or proof checking was supplied in this session.
