src/rules/laws/unsafe.bend checks

raw source on the hub · import 0xd96f2ab40f5df4925c42e96d0ba857ff/src/rules/laws/unsafe.bend as Unsafe

rule unsafe (project-wide): an @unsafe def that a LAWS.bend or PROOF.bend reaches by relative imports, over the files bolt read. The checker skips its termination check, prints "All terms check, but N defs rely on unsafe or foreign code:" (2.0.16: "with N unsafe annotation(s).") and exits 0, so a gate that only reads the exit status goes green on a proof that is not sound (a def that never returns proves anything). Recurse on a shrinking argument, or on a fuel, and drop the @unsafe; or keep the def out of what the laws import. An @unsafe def no law file reaches is not this rule's business. The rule reads each file's digest (src/rules/digest.bend), and takes every closure over one import graph.
