F430 reuses an ephemeral, warmed Z3 memory image on one Linux host by forking a single-thread parent. It is not a portable serialized solver state, a cross-node heap transfer protocol, or a guarantee that Z3 reuses every learned clause. The oracle compares mechanism cost against same-version cold Z3 processes for a fixed one-byte prefix. The 2.252x and 2.249x ratios do not establish end-to-end symbolic-execution throughput, fuzzing coverage, time-to-target, or bug-finding uplift. Those claims require repeated paired public-target campaigns. SAT remains subject to backend and QueryStore Query IR validation. UNSAT remains unknown unless the separately configured authorization policy accepts it. A target timeout preserves the parent snapshot, but portfolio cancellation kills the process group and discards it.
