The `child_process` require string, hostnames, and fs method names are assembled from array-joined fragments to evade static detection. The package advertises itself as a BNPL storefront-block `state container` but ships only a trivial 24-line Store class plus the dropper and an unreferenced lib/telemetry.js containing the same fetch-write-exec routine — a cover-story shape indicating typosquat/impersonation intent.
