Foundations of the trace assertion method of module interface specification
Bibliographic record
Abstract
The trace assertion method is a formal state machine based method for specifying module interfaces. A module interface specification treats the module as a black-box, identifying all the module's access programs (i.e., programs that can be invoked from outside of the module) and describing their externally visible effects. In the method, both the module states and the behaviors observed are fully described by traces built from access program invocations and their visible effects. A formal model for the trace assertion method is proposed. The concept of step-traces is introduced and applied. The stepwise refinement of trace assertion specifications is considered. The role of nondeterminism, normal and exceptional behavior, value functions, and multiobject modules are discussed. The relationship with algebraic specifications is analyzed. A tabular notation for writing trace specifications to ensure readability is adapted.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
