AllPages enumerates the union's distinct pages, collapsing chorus (same key across shards) and equivalence-bound identities into one entry via union-find, noting divergence when members' bodies differ (collapse acknowledged, not silent). SiteMap builds the namespace tree from page placements, spanning shards. Both derived/recomputable and presentation-free. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
