How Good is Static Analysis at Finding Concurrency Bugs?
Why this work is in the frame
A frame that forgets how it found something cannot be audited. These are the routes that admitted this work.

Abstract
Detecting bugs in concurrent software is challenging due to the many different thread interleavings. Dynamic analysis and testing solutions to bug detection are often costly as they need to provide coverage of the interleaving space in addition to traditional black box or white box coverage. An alternative to dynamic analysis detection of concurrency bugs is the use of static analysis. This paper examines the use of three static analysis tools (Find Bugs, J Lint and Chord) in order to assess each tool's ability to find concurrency bugs and to identify the percentage of spurious results produced. The empirical data presented is based on an experiment involving 12 concurrent Java programs.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
