Что бы ты просто понимал. Там где read_contact : DEBUG это выводится как раз из структуры

if (strcmp(argv[1], "read") == 0)
    {
        Contact *contacts = NULL;
        uint8_t count = read_contacts(contacts);

        printf("[DEBUG READ FUNC] count = %d\n", count);

        for (uint8_t i = 0; i < count; i++)
        {
            printf("\n\nloop init\n\n");
            printf("%s | %s\n", contacts[i].name, contacts[i].phone);
        }

        free(contacts);
    }
