Boundary

"Lab leak" is not one hypothesis.

semantic trap / refusal

Boundary

"Not genetically engineered" does not mean "not laboratory-associated."

semantic trap / refusal

Boundary

"Laboratory-associated" does not mean "engineered."

semantic trap / refusal

Boundary

"Engineered" does not mean "deliberately released."

semantic trap / refusal

Boundary

"Zoonotic origin" does not automatically mean "the first human infection occurred at the Huanan market."

semantic trap / refusal

Boundary

"The Huanan market was the early epicenter" does not automatically mean "the market was definitively the first spillover site."

semantic trap / refusal

Boundary

Animal DNA in a SARS-CoV-2-positive environmental sample does not prove the animal itself was infected.

semantic trap / refusal

Boundary

No positive animal sample after market closure does not prove no infected animal had been present before closure.

semantic trap / refusal

Boundary

An environmental swab can contain material from animals, humans, products and surfaces. Co-location is evidence, not a direct host diagnosis.

semantic trap / refusal

Boundary

Two early viral lineages do not by themselves constitute directly observed two animal-to-human jumps.

semantic trap / refusal

Boundary

A peer-reviewed model favoring multiple introductions is not a directly witnessed spillover event.

semantic trap / refusal

Boundary

An erratum that reduces a Bayes factor does not necessarily reverse the paper's conclusion.

semantic trap / refusal

Boundary

"Closest known relative" is not "direct progenitor."

semantic trap / refusal

Boundary

"No direct progenitor has been found" is not proof of laboratory origin.

semantic trap / refusal

Boundary

"No lab-origin precursor has been found" is not proof of zoonotic origin.

semantic trap / refusal

Boundary

Absence of evidence and evidence of absence are not interchangeable.

semantic trap / refusal

Boundary

A low-confidence intelligence assessment is not a 51% probability statement.

semantic trap / refusal

Boundary

Counting agencies is not the same as weighting probabilities.

semantic trap / refusal

Boundary

Scientific evidence and intelligence evidence are different source classes.

semantic trap / refusal

Boundary

"The U.S. Intelligence Community concluded..." is dangerous without date.

semantic trap / refusal

Boundary

An ODNI press release authored under a DNI is not automatically a new coordinated Intelligence Community Assessment.

semantic trap / refusal

Boundary

FBI position ≠ entire IC position.

semantic trap / refusal

Boundary

House majority report ≠ Congress-wide scientific finding.

semantic trap / refusal

Boundary

House minority report ≠ entire Democratic Party or scientific community.

semantic trap / refusal

Boundary

A congressional "sense of Congress" is not an intelligence finding.

semantic trap / refusal

Boundary

WHO-China 2021 team's "extremely unlikely" lab-incident ranking did not close the WHO organizational question.

semantic trap / refusal

Boundary

WHO SAGO 2025's "weight of available evidence" favoring zoonosis is not equivalent to "origin established."

semantic trap / refusal

Boundary

SAGO's inability to assess an accidental laboratory event because key information was unavailable is not positive evidence that such an event occurred.

semantic trap / refusal

Boundary

Missing data can block exclusion without increasing a hypothesis to parity.

semantic trap / refusal

Boundary

SAGO reports that it lacked original raw data from any source for much of its work.

semantic trap / refusal

Boundary

China's non-provision of requested data is important, but SAGO also describes information requests to multiple countries.

semantic trap / refusal

Boundary

The March 2020 "Proximal Origin" paper addressed genomic evidence and purposeful manipulation; its wording should not be used as an all-time adjudication of every possible lab-associated scenario.

semantic trap / refusal

Boundary

Scientific papers can be corrected.

semantic trap / refusal

Boundary

WHO reports themselves can be updated/corrected.

semantic trap / refusal

Boundary

"Consensus" is a social/institutional claim requiring a defined population and date.

semantic trap / refusal

Boundary

A source may be authoritative about what an institution believes while weak about the underlying origin.

semantic trap / refusal

Boundary

Political criticism of a scientific or intelligence process is not itself origin evidence.

semantic trap / refusal

Boundary

Evidence that coronavirus research occurred at WIV is not evidence that SARS-CoV-2 was present there before the outbreak.

semantic trap / refusal

Boundary

Evidence of biosafety concerns is not evidence of a specific infection event.

semantic trap / refusal

Boundary

Evidence that researchers were ill is only origin-relevant if illness, date, pathogen and exposure are established. Nonspecific illness is not a COVID diagnosis.

semantic trap / refusal

Boundary

"Gain-of-function" has multiple policy/scientific definitions.

semantic trap / refusal

Boundary

A research proposal is not proof that the proposed experiment occurred.

semantic trap / refusal

Boundary

Early-case ascertainment can bias spatial analysis.

semantic trap / refusal

Boundary

A market can be both an early amplifier and a spillover site; evidence for one role does not mathematically exclude the other.

semantic trap / refusal

Boundary

This dossier must be comfortable ending with BEST SUPPORTED BUT NOT ESTABLISHED and UNRESOLVED.
