Expanded, formally-written preprint version of S-24 - Crits-Christoph et al. — Genetic evidence of susceptible wildlife in SARS-CoV-2-positive Huanan market samples (Zenodo report), analysing >800 environmental samples (Jan 1 – late Mar 2020) plus the Jan 2020 animal samples. Adds: phylogenetic placement of the 4 recovered environmental genomes (A20/B5/F13/F54) showing their tMRCA matches the pandemic-wide tMRCA; a stall-level map of SARS-CoV-2 positivity vs. susceptible-wildlife mtDNA; and detection of other animal viruses (raccoon dog-, civet-, bamboo rat-infecting) co-located with SARS-CoV-2. Later published, with additional revision, as S-35 - Crits-Christoph et al. — Genetic tracing of market wildlife and viruses at the epicenter of the COVID-19 pandemic (Cell). relevance_note: the fullest pre-peer-review write-up of the stall-level co-location evidence; near-identical content basis to the published Cell version. superseded_by: “S-35 - Crits-Christoph et al. — Genetic tracing of market wildlife and viruses at the epicenter of the COVID-19 pandemic (Cell)
