No sequence filtering applied to the CASP16 affinity benchmark
Leakage control of CASP16 affinity challenge, Boltz-2 against the top-ranked participants
The sequence-level filtering described in appendix D.2.1 was not applied to CASP16, because the CASP16 data was released after the training-data cutoff. The maximum Tanimoto similarity of test compounds to the affinity training set is stated as 0.41 for L1000 and 0.59 for L3000.
The leakage position the Boltz-2 supplement states for its CASP16 comparison.

- method: source-hash-verification; pdf-text-parse; independent-cell-check; rendered-source-visual-check; ai-assisted-source-review; method note: Re-retrieved all three sources and matched each pinned SHA-256. Re-rendered the Boltz-2 supplement with pdftotext -layout (poppler 26.08.0) and matched the text layer's recorded SHA-256. Re-read all 256 cells with a parser written for this review that does not import the extraction script, matching each result to its cell through its own source_locator, and separately read appendix tables 11, 12 and 14 from PNG renderings of PDF pages 29 and 30 at 160 dpi, and Ross Table 3 from the pinned XML markup. Checked printed value, numeric value, locator, metric concept, qualifier, direction, unit, uncertainty and the linked configuration, protocol and dataset, and that every N/A or '-' cell is recorded as missing with a reason.; reviewer: claude; reviewer note: Claude review agent, independent of the extraction agent; no human review claimed; reviewed at: 2026-10-22T13:40:00Z; artifact sha256: be867a5d92add8b223d47d882a4213ad489741f3e4d5081a0901a54370342569; retrieval url: https://www.ebi.ac.uk/europepmc/webservices/rest/PMC12262699/supplementaryFiles; note: Independent review 2026-10-22: the quoted wording was matched against the pinned artifact and the locator checked.
