s1-code v1

First version of s1-code. For use, prefer v3. A System One decision model (322M, CPU) that returns the probability that a Python function answers a search. Fine-tuned from convaiinnovations/laya (Apache 2.0).

Same input format as v3: the state is the file path, the function name, an empty line and the first 1,500 characters of the source; the question is the noul This code answers the search: <your search>.
