open string

By default, fibor always starts out as an open string [randomly coiled loopstring➿ with two (2) endpoints]*. The objective is to twist and thus efficiently close🔒 this string (a process known generically as folding).** Egglepple-wise, no instance exists where a string sits in freespace; endpoints are always attached to a membrane.
