Method populate_file_index

atomic-repository/src/repository/materialize.rs:994–1031

Populate the file index for all tracked files after a materialize. Stats each tracked file from disk and stores its mtime + size + content hash in the pristine database. Errors are silently ignored (best-effort). Why we ignore `result.file_results` and walk the tracked set: the `MaterializeResult.file_results` map is only populated when `merge_file_result(_, store_result=true)` is called, and th

(&self, _result: &MaterializeResult)
