- ~T~ = the target CoC member/Cluster ID chosen by the CoC client at the time of ~append()~
- ~u~ = the Machi file server unique opaque file name suffix, e.g. a GUID string

3. CoC client choose some CoC locator value ~L~ such that
~rs_hash_with_float(L,Map) = T~ (see below).
4. CoC client sends its request to cluster
~T~: ~append_chunk(p,L,N,...) -> {ok,p.L.N.u,ByteOffset}~
5. CoC stores/uses the file name ~F = p.L.N.u~.

5. CoC stores/uses the file name ~F = p^L^N^u~.
** The details: CoC file read
1. CoC client knows the file name ~F = p.L.N.u~ and parses it to find
the values of ~L~ and ~N~.
1. CoC client knows the file name ~F~ and parses it to find
the values of ~L~ and ~N~ (recall, ~F = p^L^N^u~).
2. CoC client knows the CoC ~Map~ for type ~N~.
3. CoC calculates ~rs_hash_with_float(L,Map) = T~
4. CoC client sends request to cluster ~T~: ~read_chunk(F,...) ->~ ... success!
