Abstract
The development of simulation models for complex systems can be difficult and time consuming. This makes the ability to re-use modelling components of high value. To be able to re-use modeling components it is important to know the context within which a given component was developed. Experimental Frames are useful for capturing this context. We present the CD++ Repository -- an internet based searchable database of re-usable CD++ DEVS models and their Experimental Frames. CD++ Repository facilitates the re-use of models and allows users in different geographical locations to collaborate in building complex models. The database is built as a hierarchy of the stored atomic and coupled models, thus eliminating repetition. One of the key features is that along with the storage of the atomic and coupled models, it stores Experimental Frames for each model, which allows users to easily determine the context for which a given model applies.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.
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
