Abstract
In run-time safety analysis the executions of a concurrent program are monitored and analyzed with respect to safety properties. Similar to testing, run-time analysis is quite efficient, but it also tends to be incomplete. The results pertain only to the observed executions which may constitute just a small subset of all possible executions. In this paper, we describe a tool called ViP which uses the software model checker VeriSoft to perform comprehensive run-time safety analyses of concurrent C/C++ programs. A ViP analysis proceeds in three fully automated steps: First, the input program is prepared for a VeriSoft analysis through instrumentation. Next, VeriSoft is invoked to generate the traces corresponding to all possible executions of the program. Then, the traces are checked efficiently for specification violations. The instrumentation is based on the source code transformation language TXL. TXL allows for the instrumentation to be described in terms of rewrite rules and gives ViP a remarkable amount of flexibility. The paper describes ViP together with its use of VeriSoft and TXL. Several sample analyses are discussed to illustrate the use of ViP.

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
