FGB direct evidence guide

The review YAML is the decision authority. The source records retain every direct source key, zero-based index, method and locator without duplicating decision prose. Product boundaries distinguish parent-source identities from curated processing metadata; literature notes explain the biological synthesis.

Evidence is assessed at the claim's actual scope. Human beta-chain assembly supports structural complex participation. Intact-fibrinogen receptor or cellular responses are not isolated beta-chain activities. Positive matrix classification can be supported independently at gene level while a particular unavailable high-throughput target/sample record remains uncertain. The external platelet-surface location is more precise than its cell-surface parent (GO:0009897 part_of GO:0009986); the broader structural molecular function still covers soluble-complex assembly beyond matrix incorporation.

For generic binding, the positive cellular association is retained as non-core unless a more informative function is demonstrated. GO:0046790 requires a virion, so an expressed core-protein construct does not establish it. GO:0051087 describes binding to a chaperone and is compatible with the beta chain being a client. These decisions follow the project's curation instructions; no new publication quotations are introduced.
