This should be egregious unless the GitHub CI is so inperformant it's breaking
Tendermint consensus's synchrony expectations, which likely points to our own
code being unviable.
This solely serves as an immediate fix to the problem, not a justification of
the unevaluated performance.
Putting a signer first doesn't work because signers can only publish once a
supermajority sync. Now, the code uses an excluded signer (instead of an
included signer) to determine signing set.
Further simplifications are available. Also adds accurate documentation on
latency/sleep reasoning.
It's largely unoptimized, and not yet exclusive to validators, yet has basic
sanity (using message content for ID instead of sender + index).
Fixes bugs as found. Notably, we used a time in milliseconds where the
Tributary expected seconds.
Also has Tributary::new jump to the presumed round number. This reduces slashes
when starting new chains (whose times will be before the current time) and was
the only way I was able to observe successful confirmations given current
surrounding infrastructure.
