verification note
Scanned proposal downloaded from the Internet Archive 2026-08-26 and read; the requested amount, partner list, and the S2 proteolytic-cleavage passage confirmed at PDF p. 13 (printed p. 11) by two independent OCR passes that agree on every substantive word. The document has no born-digital text layer, so all quotations from it are OCR-derived and footnote superscripts were dropped rather than guessed.
reliability notes
  • Chain of custody is weak: this is a third-party user upload to a public archive in December 2023, not an official government release or an authenticated FOIA production. Its authenticity is corroborated independently — draft versions appear in a federal FOIA release and a congressional committee treats it as genuine — but this specific file has no official provenance.
  • The document establishes only what a funding application proposed. It does not establish that any proposed work was performed, funded, or attempted, and DARPA did not fund it — confirmed by the congressional record, contemporaneous reporting, and a negative check of federal award data.
  • Names living individuals. Any claim built on it takes the form 'the proposal states the team would do X', never 'the team did X'.

The proposal's cleavage-site passage, at a confirmed locator

what the source states
Under the run-in heading "S2 Proteolytic Cleavage and Glycosylation Sites": "We will analyze all SARSr-CoV S gene sequences for appropriately conserved proteolytic cleavage sites in S2 and for the presence of potential furin cleavage sites. SARSr-CoV S with mismatches in proteolytic cleavage sites can be activated by exogenous trypsin or cathepsin L. Where clear mismatches occur, we will introduce appropriate human-specific cleavage sites and evaluate growth potential in Vero cells and HAE cultures." The proposal requested $14,209,245 across 3.5 project years, with performance sites including Kunming and Wuhan, China; Chapel Hill; New York; Singapore; Palo Alto; and Madison.
what we infer
A documented pre-pandemic intention, in a program with a Wuhan partner, to insert precisely the class of feature the pandemic virus carries. That is a real and uncomfortable coincidence of technique and timing, and it is evidence about what was proposed — not about what was done, which is graded separately. The non-award belongs beside the quotation wherever the quotation appears.
limitations
  • The text is OCR-derived from an image-only scan; two independent passes agree on every substantive word, and footnote superscripts were dropped rather than guessed.
  • The available copy is a third-party archive upload, not an official release or authenticated FOIA production.
  • The proposal was not funded, confirmed by the congressional record, contemporaneous reporting, and a negative check of federal award data.
  • A phrase widely attributed to this document — about a cleavage site 'able to interact with furin' — is not proposal text but a journalist's wording, and is not quoted here.
