Match memory failures to the exact source identity instead of graph ordering. Preserve CLI parse, file-evidence, partial-result, later-source and unchanged-input checks across valid memory-pressure outcomes. Use a controlled parent heap envelope with a real owned analyzer to prove module retention and graph rejection independently of host GC timing.
Validation: full check:ci passed; 17 focused tests passed, with the final 4 changed tests rerun successfully. Independent test-strength and isolation review passed. The earlier hosted failure exposed missing graph-only fields; its exact alternate memory stage was not captured.
