verification note: Fetched 2026-08-26; the stated positions verified. Recorded as a government position statement, not as evidence.
reliability notes: A state position paper from the government holding the records this case most needs; it declares China's origins investigation complete, which is itself the central obstacle the research agenda addresses.
Admitted so that the custodian's stated position is on the record alongside the requests it has declined, never as evidence about the origin.

what the source states: The April 2025 white paper states that a laboratory leak is extremely unlikely, directs attention toward the United States, and declares China's origins investigation complete.
what we infer: Recorded as a position statement, never as evidence. Its significance for this case is structural rather than evidential: the government holding the early sequences, the market-animal records, and the laboratory documentation has declared the matter closed, which is the binding constraint on nearly every decisive test in the research agenda.
limitations: A government position paper from an interested party; it presents no new primary data.
