Abstract
Stream processing is a programming paradigm that is growing in popularity due to the presence of an increasing number of academic and commercial platforms. However, there exist few tools and methodologies to properly test a program that manipulates streams; in particular, model-based testing techniques need to be adapted to the particularities of stream processing. The paper suggests that pre/post models on stream programs be specified in the form of runtime monitors, themselves implemented as stream programs. It also describes how test inputs satisfying a given precondition can be generated automatically, through a mechanism that inverts the operation of a stream processing pipeline. A proof-of-concept library implements these concepts for the specific case of the BeepBeep event stream processing library, and is evaluated experimentally. The approach can successfully find satisfying input cases for pre-conditions involving non-trivial constructs such as sliding windows, aggregations and filtering.

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
