Saty 09d1091775 Peer review decides by margin: "same" ahead by three accepts
Four (five after an objection) "same" could not be reached with the few
accounts online: an author never reviews their own work, and with four
active accounts that were also the authors, each function could get at most
three verdicts. 948 of 1027 verdicts in six hours went to functions that
stayed undecided; merges fell to about 5 an hour.

- Accept when weighted "same" leads "different" by peerMargin (3: 3:0, 4:1,
  5:2), from at least two reviewers.
- Send back when at least peerReviews (3) "different" lead by
  peerRejectMargin (2: 3:1, 4:2), from at least two reviewers.
- Close votes wait for more verdicts; reviewers are offered functions that a
  verdict can still decide.
- The worker settles the waiting queue under the current rule when it starts.
- Trust and quality count accepted and sent-back functions the same way.
