Abstract
Real-time process algebra (RTPA) is a mathematics-based notation system for the specification and refinement of realtime and safety-critical systems. This paper presents the work on designing and developing a set of tools that facilitate automatic generation of C++ code from RTPA specifications of system architectures and behaviors. A two-phrase strategy has been employed in the design of the toolkit. In the first phrase, an RTPA specification is lexically and syntactically analyzed and type-checked, which results in a set of abstract syntax trees. In the second phrase, C++ code is generated using the RTPA-to-C++ mapping strategies and patterns when walking down the abstract syntax trees. The RTPA-to-C++ mapping strategies specify both the traditional sequential part of RTPA mapping onto the standard C++ library and the real-time features of RTPA, such as interrupt, concurrency, duration, and event/time-driven dispatch, mapping onto the RTPA run-time library, which provides real-time support and is implemented using real-time kernel techniques. The toolkit implemented includes an RTPA lexer, an RTPA parser, an RTPA type-checker, and an RTPA code-generator. The experimental results show that RTPA specifications can be rigorously checked and corresponding C++ code can be automatically generated from RTPA specifications using the toolkit. The automatically generated code is executable and effective under the support of the standard C++ library and the specially developed RTPA run-time library

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
