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.

InformationSpace.git_backed(space_id, repo_path) wires the git coordination log;
the default constructor stays in-memory for tests (new keyword-only store=). A
one-time importer (migrate_space / import_log / JSONL export+import) replays an
existing in-memory or JSON log into git verbatim — preserving seq, timestamp and
actor (union-without-erasure) and refusing out-of-order import. Same fold after
migration; no behavioural change to overlay/union. SCOPE updated; WP-0009 done.

edit()/overlay()/apply_overlay() on InformationSpace. edit() unifies the write
path through one principled route — draft overlay then apply: write-through-capable
target fast-forwards (APPLIED), read-only target keeps the draft as local truth
(KEPT_DRAFT), external drift refuses (no clobber). Integration tests cover all
four. 64 tests green, pyflakes clean. Flips WP-0008 done.

InformationSpace ties the slice together: conformance-gated attach → resolve →
read, with alias() recording coordination decisions in the log. Exposed from the
package root. End-to-end integration test (two folder shards → union read with
layered provenance + chorus + alias redirect + red-link + nonconformant-rejected).
pyflakes clean, 39 tests green. Flips WP-0007 done.
