I suggest adding the pointer check to prevent UB. The behavior will not change, but the static analyzer will stop triggering.

if (data) { \
memcpy(store->Data(), data, size); \
} \
auto ab = ArrayBuffer::New((isolate), std::move(store)); \
(result) = Uint8Array::New(ab, 0, size); \
break; \

This looks legit.

r = sqlite3_exec(db, init_sql_v0.data(), nullptr, nullptr, nullptr);
CHECK_ERROR_OR_THROW(env(), r, SQLITE_OK, Nothing<void>());
auto stmt = stmt_unique_ptr(s);
