Metadata does not show them to be one release. They are different artefact kinds (weights repo vs code repo) with no cross-reference by commit or tag, and 5005e823 (2026-06-07, a README-redirect merge) postdates every HF weight file (latest 2025-07-11) and the HF head (2025-11-19, README only). They are compatible by file name: all eight checkpoint paths the code names exist in the HF snapshot. They differ on guardrails: the code at 5005e823 loads Cosmos-Guardrail1 and Llama-Guard-3-8B from separate repos, while the HF snapshot bundles a guardrail/ folder (Cosmos-Guardrail1 contents plus an Aegis/LlamaGuard-7b folder) that predates GitHub commit b7b20fec, which replaced Aegis with Llama Guard 3.

Curator qualifications: Commit dates and contents verify the chronology: GitHub replaced Aegis with Llama Guard 3 on 2025-04-28, and the 2026-06-07 head is a README-redirect merge. The producer treats the HF snapshot and GitHub head as the same model family, compatible by file name but not one release; that is correctly labelled a proposal. HF tree file dates and the 99/100 oid overlap were not re-derived.
