Abstract
In current class-based Object-Oriented Programming Languages (OOPLs), object types include only static features. How to add object dynamic behaviors modeled by Harel's statecharts into object types is a challenging task. We propose adding states and state transitions, which are largely unstated in object type theory, into object type definitions and typing rules. We argue that dynamic behaviors of objects should be part of object type definitions. We propose our type theory, the τ -calculus, which refines Abadi and Cardelli's ζ -calculus, in modeling objects with their dynamic behaviors. In our proposed type theory, we also explain that a subtyping relation between object types should imply the inclusion of their dynamic behaviors. By adding states and state transitions into object types, we propose modifying programming language constructs for state tracking.

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
