Three documents are retrieved at immutable repository commits and SHA-256 checked. Diff compares line multiplicity, so moves/reordering may not appear as semantic changes. No automatic YMYL publication, no vote collection, and no independently running node. Later September outcome retrieval remains blocked on the direct forum path; primary Foundation evidence is available for distinct historical rounds. All document content remains available without JavaScript; interactive filtering needs JavaScript.
