Create/Get for submission (including the one legitimate status transition — submission is not append-only, unlike the other three), Create/GetLatest for extraction and evidence_package, Create for finding plus ListCurrentFindings which applies the anti-join documented in the migration (a finding referenced by another row's `supersedes` is not "current"). Tested against real Postgres, including that the append-only trigger still rejects UPDATE on evidence_package via this new code path, and that ListCurrentFindings actually hides a finding once a correction supersedes it.
