Step 1 — Consolidated source pool (1c consolidator)
17 sources, S-1–S-17, from two blind searchers on disjoint data axes (epi-field: S-1–S-8; genomic-institutional: S-9–S-17). No duplicates found (checked; see note below). Grouped by line-of-evidence, each split by side — best-first within each side, ordering only, no scores (step 2’s job).
A. Case geography/timing & market-epicenter claim
- Zoonosis: S-1 - Worobey 2022 Science - Huanan market case geolocation identifies it as the COVID-19 pandemic’s early epicenter
- Research-related (statistical critique of A’s zoonosis case, not itself an affirmative lab-leak finding): S-7 - Stoyan & Chiu 2024 JRSS-A - Statistical critique of Worobey 2022’s market-epicenter proof
B. Market wildlife trade & environmental/animal samples
- Zoonosis: S-2 - Liu 2023 Nature - China CDC environmental and animal surveillance at the Huanan market, S-3 - Crits-Christoph, Débarre, Worobey et al. 2024 Cell - Susceptible wildlife DNA co-located with SARS-CoV-2 in Huanan market samples, S-4 - Xiao et al. 2021 Scientific Reports - Wildlife species sold live at Wuhan markets 2017-2019
- Research-related: none — flagged gap (see audit)
C. Market-vs-lab ascertainment bias & data-suppression record
- Research-related-leaning (critiques/non-transparency, not affirmative lab-leak data): S-5 - Bloom 2021 MBE - Recovered deleted early-Wuhan sequences suggest ascertainment bias toward market-linked viruses, S-8 - Reuters 2021 (Dwyer) - China gave WHO team only summary data, not raw line lists, on the 174 earliest COVID-19 cases
D. Official field investigation
- Neutral/contested (primary field data, contested “extremely unlikely [lab leak]” framing): S-6 - WHO-China Joint Report 2021 - Field mission epi-curve and market investigation into the origins of SARS-CoV-2
E. Furin cleavage site
- Zoonosis: S-9 - Andersen 2020 Nature Medicine - Proximal Origin argues the furin cleavage site is explicable by natural evolution
- Research-related: S-10 - Segreto & Deigin 2021 BioEssays - argues SARS-CoV-2’s chimeric structure and furin site do not rule out a laboratory origin
F. Closest known viral relatives (RaTG13/BANAL)
- Neutral/foundational (cited by both sides): S-11 - Zhou 2020 Nature - first report of RaTG13, SARS-CoV-2’s closest known bat-coronavirus relative at the time
- Zoonosis: S-12 - Temmam 2022 Nature - BANAL bat coronaviruses from Laos are SARS-CoV-2’s closest known relatives and infect human cells
G. Lineage A/B & restriction-site molecular evolution
- Zoonosis: S-13 - Pekar, Worobey, Wertheim et al. 2022 Science - lineage A and B imply at least two independent zoonotic spillovers
- Research-related: S-14 - Bruttel, Washburne & VanDongen 2022 bioRxiv preprint - restriction-site pattern argued to be a synthetic-assembly fingerprint (contested, non-peer-reviewed)
H. WIV documents & government/congressional investigations
- Research-related: S-15 - DEFUSE proposal 2018 - leaked EcoHealth Alliance-WIV DARPA grant application proposing furin cleavage site insertion into bat coronaviruses, S-16 - US House Select Subcommittee on the Coronavirus Pandemic final report, Dec. 2024 - concludes COVID-19 most likely emerged from a WIV lab, S-17 - Bostickson & Demaneuf (DRASTIC) 2021 - investigation into WIV virus databases taken offline in 2019
- Zoonosis: none — structural gap, no neutral/zoonosis-side primary exists here (see audit)
Recurring datasets (expect shared data-basis D-nodes at step 2)
- Huanan market environmental-swab dataset — same raw China-CDC-collected swabs underlie S-2 (original) and S-3 (independent reanalysis); two independent interpretations of one dataset, not two datasets.
- Worobey 2022 case-geolocation compile (S-1) — a single assembled record (leaked/court-obtained/WHO-report fragments); later citations of its numbers (e.g. within S-7’s critique) aren’t independent new evidence.
- SARS-CoV-2 reference genome / GISAID sequence collection — underlies S-9, S-10, S-13, S-14 (each targets a different genomic feature/method, not a restatement).
- RaTG13 (S-11, WIV) vs BANAL (S-12, separate Laos expedition) — two distinct “closest known relative” datasets; do not conflate.
Exclusions (union of both searchers)
- Pekar, Worobey, Wertheim et al. 2022 Science (lineage A/B) — surfaced in epi-field slice, correctly deferred to genomic slice as S-13 (boundary call, not a duplicate: distinct DOI/method from S-1).
- Andersen et al. 2020 “Proximal Origin” — surfaced in epi-field slice, deferred to genomic slice as S-9.
- Furin-site/RaTG13/BANAL/DEFUSE/WIV-database material surfaced while mining the ACX post from the epi-field side — deferred to genomic slice, not individually itemized.
- WHO-China Joint Report — surfaced in genomic slice, correctly deferred to epi-field slice as S-6.
- Bloom 2021 (NCBI SRA deletion) — surfaced in genomic slice while distinguishing it from the WIV Sept-2019 takedown (S-17); correctly deferred to epi-field slice as S-5 (two different data-suppression events, two different institutions/times).
- Bloom, Virus Evolution 2023 — third independent reanalysis of the same Huanan swabs already covered by S-2/S-3; recurring-dataset cap, not noded; summarized in prose in S-3’s body.
- “A Critical Reexamination of Recovered SARS-CoV-2 Sequencing Data” (bioRxiv 2024/MBE 2025) — reanalysis of S-5’s same recovered sequences; not noded, summarized in S-5’s relevance_note.
- “Was Wuhan the early epicenter…? — A critique,” National Science Review — second, redundant critique of Worobey 2022; skipped to avoid triple-counting rebuttals (S-7 already covers this ground). Candidate for a second independent critique if step 2/3 wants one.
- US government intelligence assessments (ODNI Aug. 2021 summary + DOE “low confidence”/FBI “moderate confidence” ~2023) — named neutral/mixed anchor, content confirmed via search but not opened/minted; budget constraint. Flagged by its own searcher as the single highest-value addition if budget is revisited — the only candidate source giving a genuinely split verdict from one primary document rather than a one-sided argument.
- Alina Chan & Matt Ridley’s “Viral” (2021 book) — no genuinely original primary reporting found; treated as discovery hub only, not noded.
- DARPA’s DEFUSE rejection letter — genuine second primary document, folded into S-15’s
motivatednessfield rather than given its own node (confirms DEFUSE’s content/rejection, no new claim). - The 3 debate videos + Weissman’s/Rootclaim’s full write-ups — not separately mined beyond named anchors already in the brief, time budget; a real coverage gap on both slices, not a considered rejection.
Note on near-collision (not a duplicate): S-1 and S-13 are both Worobey-coauthored Science 2022 papers with overlapping author lists and similar titles, but distinct DOIs, methods, and claims (case geolocation vs. lineage-divergence molecular clock) — correctly kept as two separate nodes per the search plan’s explicit boundary call, not merged.
