a71e9543fe WIP: refactoring inner handling, but ... (more)
There are a couple of weird things in the snippet below (AP mode):

    22:32:58.209 b uses inner: [{epoch,136},{author,c},{mode,ap_mode},{witnesses,[]},{upi,[b,c]},{repair,[]},{down,[a]},{flap,undefined},{d,[d_foo1,{ps,[{a,b}]},{nodes_up,[b,c]}]},{d2,[]}] (outer flap epoch 136: {flap_i,{{{epk,115},{1439,904777,11627}},28},[a,{a,problem_with,b},{b,problem_with,a}],[{a,{{{epk,126},{1439,904777,149865}},16}},{b,{{{epk,115},{1439,904777,11627}},28}},{c,{{{epk,121},{1439,904777,134392}},15}}]}) (my flap {{epk,115},{1439,904777,11627}} 29 [{a,{{{epk,126},{1439,904777,149865}},28}},{b,{{{epk,115},{1439,904777,11627}},29}},{c,{{{epk,121},{1439,904777,134392}},26}}])

    22:32:58.224 c uses inner: [{epoch,136},{author,c},{mode,ap_mode},{witnesses,[]},{upi,[b,c]},{repair,[]},{down,[a]},{flap,undefined},{d,[d_foo1,{ps,[{a,b}]},{nodes_up,[b,c]}]},{d2,[]}] (outer flap epoch 136: {flap_i,{{{epk,115},{1439,904777,11627}},28},[a,{a,problem_with,b},{b,problem_with,a}],[{a,{{{epk,126},{1439,904777,149865}},16}},{b,{{{epk,115},{1439,904777,11627}},28}},{c,{{{epk,121},{1439,904777,134392}},15}}]}) (my flap {{epk,121},{1439,904777,134392}} 28 [{a,{{{epk,126},{1439,904777,149865}},28}},{b,{{{epk,115},{1439,904777,11627}},28}},{c,{{{epk,121},{1439,904777,134392}},28}}])

    CONFIRM by epoch inner 136 <<103,64,252,...>> at [b,c] []

    Priv1 [{a,{{132,<<"Cï|ÿzKX:Á"...>>},[a],[c],[b],[],false}},
           {b,{{127,<<185,139,3,2,96,189,...>>},[b,c],[],[a],[],false}},
           {c,{{133,<<145,71,223,6,177,...>>},[b,c],[a],[],[],false}}] agree false
    Pubs: [{a,136},{b,136},{c,136}]
    DoIt,

1. Both the "uses inner" messages and also the "CONFIRM by epoch inner 136"
   show that B & C are using the same inner projection.

   However, the 'Priv1' output shows b & c on different epochs, 127 & 133.
   Weird.

2. I've added an infinite loop, probably in this commit.  :-(

Scott Lystig Fritchie
14fad2d704 End-to-end chain state checking is still broken (more)
If we use verbose output from:

    machi_chain_manager1_converge_demo:t(3, [{private_write_verbose,true}, {consistency_mode, cp_mode}, {witnesses, [a]}]).

And use:

    tail -f typescript_file | egrep --line-buffered 'SET|attempted|CONFIRM'

... then we can clearly see a chain safety violation when moving from
epoch 81 -> 83.  I need to add more smarts to the safety checking,
both at the individual transition sanity check and at the converge_demo
overall rolling sanity check.

Key to output: CONFIRM by epoch {num} {csum} at {UPI} {Repairing}

    SET # of FLUs = 3 members [a,b,c]).
    CONFIRM by epoch 1 <<96,161,96,...>> at [a,b] [c]
    CONFIRM by epoch 5 <<134,243,175,...>> at [b,c] []
    CONFIRM by epoch 7 <<207,93,225,...>> at [b,c] []
    CONFIRM by epoch 47 <<60,142,248,...>> at [b,c] []
    SET partitions = [{c,b},{c,a}] (1 of 2) at {22,3,34}
    CONFIRM by epoch 81 <<223,58,184,...>> at [a,b] []
    SET partitions = [{b,c},{b,a}] (2 of 2) at {22,3,38}
    CONFIRM by epoch 83 <<33,208,224,...>> at [a,c] []
    SET partitions = []
    CONFIRM by epoch 85 <<173,179,149,...>> at [a,c] [b]
