No files, tests, or entry points are named in the report. Start by locating the logic that assigns the deterministic field for subgraph failures, then reproduce it with the listed missing-field, division-by-zero, duplicate-entity, and WASM errors; done means deterministic failures are no longer reported as non-deterministic.
