Expose backlinks(name), recent_changes(), all_pages(), site_map() on
InformationSpace. Integration test exercises all four over two shards (BackLinks
aggregate across shards, AllPages/SiteMap span the union, RecentChanges merges an
alias decision with shard edits). SCOPE updated; WP-0010 done. 152 tests green.

WP-0009 git-backed DecisionLog + per-space append authority (keystone backing);
WP-0010 derived views (wikilinks, BackLinks, RecentChanges, AllPages/SiteMap);
WP-0011 incremental union + equivalence index + I-2 verification;
WP-0012 second adapter (git-IS-store) validating the contract on a new substrate.
