Function build_check_context 

pub async fn build_check_context(
    engine: &Arc<Engine>,
    repo_id: Uuid,
    changeset_files: &[String],
    work_dir: &Path,
) -> Result<CheckContext>

Build a CheckContext by querying the Engine’s graph stores for the “before” snapshot and parsing the materialized changeset files for the “after” snapshot.

Arguments

• engine — the dk-engine orchestrator (symbol store, call graph, etc.)
• repo_id — the repository UUID
• changeset_files — relative paths of changed files
• work_dir — the directory where changeset files have been materialized
