/**
 * U7 Windows FTS arm. OQ1 (does path-LOAD search the extension directory for
 * transitive DLLs?) is unanswered on this Linux workspace, so the shipping-DLL
 * arm is closed — KTD13 forbids merging shipped OpenSSL without a CVE owner.
 * The recorded arm is the vendor-neutral prerequisite.
 *
 * Registered in scripts/cross-platform-tests.ts so windows-latest must run it.
 * Assertions are unconditional: a skip-only suite would stay green if Windows
 * never ran.
