The modern bookend to the Xanadu/ZigZag dives: where those are unbuilt ideals, Roam shipped fine-grained addressing (:block/uid), live transclusion (block embeds), bidirectional links, and a queryable structured space (DataScript datoms + Datalog). Studied as a candidate DB-backed/API-attached shard (XWiki family) and as a concrete engine-hosts-adapter surface (Roam Depot onload/onunload over window.roamAlphaAPI). Added UC-50 (attach block-graph DB shard, block<->page mapping), UC-51 (adopt native span IDs as portable span addresses), UC-52 (delegate derived views to a shard's native query engine); enriched UC-32/34/35/38. Boundary: Roam is one candidate shard mapped into the Markdown-first page model, not a substrate and not the federation layer. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
