End-to-end docs journey: a group declares a kv AND a docs collection via the
string-or-table manifest; an authenticated app A docs::shared_collection(
"articles").create(#{...}), app B finds it back across the subtree (exercising
the shared find DSL); a sibling-subtree app gets CollectionNotShared;
collections ls shows both kinds; re-apply NoOp. Full journey suite 116/116.
Docs: groups-and-project-tool §11.6 (KV+docs slices shipped; files/topics/queue
deferred), sdk-shape.md (docs::shared_collection + string-or-table), CLAUDE.md.
