Template semantics for model-based notations
Bibliographic record
Abstract
We propose a template-based approach to structuring the semantics of model-based specification notations. The basic computation model is a nonconcurrent, hierarchical state-transition machine (HTS), whose execution semantics are parameterized. Semantics that are common among notations (e.g., the concept of an enabled transition) are captured in the template, and a notation's distinct semantics (e.g., which states can enable transitions) are specified as parameters. The template semantics of composition operators define how multiple HTSs execute concurrently and how they communicate and synchronize with each other by exchanging events and data. The definitions of these operators use the template parameters to preserve notation-specific behavior in composition. Our template is sufficient to capture the semantics of basic transition systems, CSP, CCS, basic LOTOS, a subset of SDL88, and a variety of statecharts notations. We believe that a description of a notation's semantics using our template can be used as input to a tool that automatically generates formal analysis tools.

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.
