FerrumOS World-Model Safety Dataset v1.0.0

An OS-level action-transition dataset collected from FerrumOS executions in QEMU. The release contains 13,697 accounted transitions from 3,639 episodes. After excluding 373 non-executed and 54 policy-only rows, 13,270 executed transitions are divided into episode-disjoint train/validation/test partitions of 9,104/2,197/1,969 rows. The corpus covers 41 observed canonical actions, of which 40 are represented in learned fitting; kernel upgrade remains policy-only. The release includes a data card, schema, manifest, checksums, episode-split audit, credential scan, and verification scripts.
