Adjudication validates exact candidate identities, result completeness, evidence, publication text, and duplicate primaries. Later and cross-file evidence can refute stale claims, while - unresolved claims remain suppressed. Semantic duplicates collapse across files and kinds + unresolved claims remain open. Semantic duplicates collapse across files and kinds only when one established defect remains; distinct defects sharing a line remain separate. - `forge/`: trait + GitHub, GitLab, Bitbucket Cloud, and Azure DevOps implementations, with self-managed base URLs where the same API contract applies.
