Mechanical change class

The class of the difference between the two retained texts. It describes what moved. It does not appraise the change, and there is no ordering between the four classes; a candidate may hold several. It is a different field from the detection class above, which is read from the observation records rather than from the two texts.

CONTENT
after that same fold, at least one word of two or more letters is present on one side and not on the other, and it is not a web address, a month name, a version keyword or a status word.

Derived over 26 differing spans: 0 excluded as markup attribute residue, 26 eligible, of which 0 matched none of the four rules. The classification reports classes and counts and never the changed text itself: reproducing a publisher’s words is quotation, and this page is not a quoting surface.

What the confirm gate read

The gate was not run. A rule resolved this candidate, and a confirm and a decline are contradictory verdicts about one candidate, so no confirm is computed where a rule has already answered.

What was decided

OSCILLATION — the before-hash returns; the publisher serves two variants

Decided by analysis, not by a person on 2026-09-07. A machine verdict is a distinct state: it is never displayed or counted as human-verified, and it can be upgraded by a person.

machine verdict, batch 31a4ac4c1bff, 2026-09-07. OSCILLATION: the before-hash returns; the publisher serves two variants

Quoted from the receipt that recorded the act. Any timestamp in it is reduced to the day it names, because this record publishes days and not times; the full value is in the confirmation ledger.

A candidate is a pair of digests that differ, and nothing more. This page reports what differed, where the bytes came from, and which rule was applied. It does not say what any change means.
