Positive environmental samples inside the Huanan market were spatially concentrated in the western section, where live-mammal vendors operated.

The 87.5% west-zone figure for interior positives comes from the Chinese CDC's own analysis and is echoed by outside reanalysis (COV-E004, COV-E005). Non-independence limits how much the two layers add together, not the observation itself.

The Chinese CDC's own 87.5% west-zone figure for interior positives corroborates the outside analysis (COV-E004, COV-E005). Non-independence limits how much this adds beyond COV-C006, not the observation itself.

The 87.5 percent west-zone figure for interior positives comes from the Chinese CDC's own paper, matching outside reanalysis (COV-E004, COV-E005). Non-independence limits how much it adds beyond COV-C006, not whether it is true.

Independent analysis and the Chinese CDC's primary dataset both confirm that 87.5 percent of interior positive samples concentrated in the market's western zone, where live wild mammals were sold. This severely restricts where the primary viral amplification occurred. The strongest opposing consideration is the unverified assertion that this specific section was uniquely poorly ventilated, which could theoretically concentrate human viral shedding regardless of the animals sold there.

Independent spatial analysis and the Chinese CDC's own surveillance data strongly align to demonstrate that 87.5% of the SARS-CoV-2-positive interior samples originated in the western section of the market. This reliably establishes the geographic clustering of the virus within the live-mammal vending area. However, without ventilation and layout documentation, it remains possible that enclosed environmental conditions concentrated human contamination independently of what was sold there.

Independent spatial models and the Chinese CDC's own internal data mutually confirm that 87.5 percent of positive interior samples came from the market's western zone. This successfully narrows the physical clustering to the exact area where live mammals were sold. The strongest opposing consideration is that unverified advocacy analyses suggest this section was poorly ventilated, meaning human shedding could independently explain the dense viral concentration.

COV-E004 documents that 87.5% of positive interior samples came from the west zone, and the associated analyses show distance to live-mammal vendors predicts positivity, so spatial concentration in that section is well established. The main objection is interpretive: some critics argue that poor ventilation and layout alone could concentrate human-derived contamination there, though this dossier does not independently verify those physical-plant claims.

Liu et al. report that 87.5% of 64 interior positives came from the west zone, and Crits-Christoph et al. independently show increased positivity near and within a wildlife stall (COV-E004, COV-E005), jointly establishing a strong west‑zone concentration. The strongest opposing consideration is the suggestion that this area may also have had the poorest ventilation, potentially concentrating human contamination, but that physical characterization has not been documented in the evidence here.

Both the Liu surveillance paper and the Crits‑Christoph reanalysis concordantly show that the vast majority of internal positives were in the west zone associated with live‑mammal vendors, and distance to such vendors predicts positivity. The strongest objection is the unverified assertion that this area was simply less ventilated and more enclosed, which, if true, could produce similar clustering from purely human shedding.

Liu 2024 states that of 64 interior positives, 87.5 percent (56/64) came from the west zone where live-mammal vendors operated; the Worobey spatial analysis separately found distance to the nearest live-mammal vendor predictive of sample positivity. The custodian's own data agreeing with the outside spatial analysis is the strongest available form of this finding, even though both layers ultimately rest on one environmental dataset. The strongest opposing consideration is an unverified advocacy characterization that the same section was the market's least ventilated enclosed area, which could concentrate human shedding independently of what was sold there.

Liu et al. report that of 64 interior positives, 87.5 percent (56 of 64) came from the west zone, and the Worobey spatial analysis separately found distance to the nearest live-mammal vendor predictive of sample positivity. Two analytic layers on the same underlying environmental dataset therefore agree on concentration where live mammals were sold. The observation narrows where to look without establishing what deposited the RNA. Strongest opposing consideration: an unverified advocacy characterization holds that the same section was the market's least ventilated enclosed area and would concentrate human shedding independently of what was sold there; this file does not confirm that layout claim.

The Chinese CDC's own interior-sample counts place 56 of 64 positives (87.5 percent) in the west zone, and a separate spatial analysis found distance to the nearest live-mammal vendor predictive of sample positivity. Two analytic layers therefore agree on concentration where live mammals were sold, which is the strongest available form of this finding even though they share an underlying dataset. The strongest opposing consideration is an unverified advocacy claim that the same section was the market's least ventilated enclosed area and would concentrate human shedding independently of what was sold there.

Two analytic layers agree on the western concentration, including the Chinese CDC's own figure of 87.5 percent of interior positives in the west zone, and the independent spatial analysis found distance to the nearest live-mammal vendor predictive of positivity. Corroboration by the custodian's dataset is the strongest form this finding could have short of new sampling. The strongest opposing consideration is the unverified claim that the west zone was the market's least ventilated section, which would concentrate human-deposited RNA independently of what was sold there; this case has not verified that characterization, so it stands as a stated objection rather than a result. The observation itself is solid; its diagnosticity remains moderate.

Two analytic layers agree: the Chinese CDC's own figure (56 of 64 interior positives in the west zone) and the published spatial analysis finding distance to the nearest live-mammal vendor predictive of sample positivity. The spatial fact itself is uncontested in the record. The strongest opposing consideration is the assertion that the west section was the market's least ventilated area, which could concentrate human-deposited RNA — but that characterization is unverified, goes to interpretation rather than the observation, and is recorded here as an objection rather than a finding. Provenance in a single underlying dataset keeps this at well_supported rather than established.

The western-section concentration is corroborated by two analytic layers including the Chinese CDC's own data (87.5 percent of interior positives in the west zone), which is the strongest form of this finding. Confidence is moderate rather than high because the layers are not independent — the spatial analysis reanalyzes the custodian's dataset. The strongest opposing consideration is the unverified claim that the west section was the market's least ventilated area, which would concentrate human-deposited RNA regardless of what was sold there; this case has not verified that characterization either way. As an observation it stands; its discriminating power is moderate.

Two analytic layers agree, including the custodian's own tabulation: 56 of 64 interior positives from the west zone, and distance to the nearest live-mammal vendor predicting positivity in the outside analysis. Independent corroboration of an outside finding by the data-holder is the strongest available form here. The strongest opposing consideration is the unverified advocacy claim that the west section was the least-ventilated part of the market, which would concentrate human-shed contamination independently of what was sold — a hypothesis this case records but no one has tested against layout documentation.

Two analytic layers agree, including the custodian's own tabulation of 56 of 64 interior positives in the west zone, and an outside spatial analysis finding distance to the nearest live-mammal vendor predictive of positivity. The strongest opposing consideration is that the two layers share one dataset and are not independent, and that the clustering has an unexcluded physical explanation: an enclosed, poorly ventilated section with concentrated human traffic would concentrate human-shed RNA identically. The ledger records that ventilation characterisation as an unverified advocacy assertion, which is the right treatment, but it remains the live alternative. The spatial pattern is well established; what deposited the RNA is not.

Two analytic layers agree, including the custodian's own tabulation that 56 of 64 interior positives came from the West Zone, and the outside spatial analysis separately found distance to the nearest live-mammal vendor predictive of positivity. The strongest opposing consideration is the unverified assertion that the west section was the market's least-ventilated area with no outside connection, which would concentrate positivity from human shedding alone; the ledger records this as stated but unverified, and no ventilation or layout documentation has been produced either way. That objection would blunt the interpretation without touching the spatial fact, which is what this claim asserts.

Two analytic layers agree, including the Chinese CDC's own figure of 87.5 percent of interior positives in the west zone.

Two analytic layers agree, including the Chinese CDC's own 87.5% figure for interior positives in the west zone (COV-E004). Cited approvingly by every dissenting seat. The non-independence caveat applies to how much this adds beyond COV-C006, not to the observation.
