+> - **Graph performance + the `brain.graph` namespace.** New `brain.graph.subgraph(seeds, opts)`
+>   (bounded multi-hop neighborhood → `{ nodes, edges, truncated }`) and `brain.graph.export(opts)`
+>   (stream the whole graph in one O(N+E) pass — the right primitive for visualizing all data
+>   instead of paging per node). `related({ node })` returns every edge incident to an entity in
+>   **both directions** in one O(degree) call. Under the hood: `related({ from/to })` now stays
+>   O(degree) under the default visibility filter (was a full scan), and the verb **and** noun
+>   pagination walks are cursor-based, so a full edge/node walk is **O(N), not O(N²)** (a consumer
+>   measured a 19k-edge whole-graph read drop from ~27s toward a single scan). These transparently
+>   use a native graph engine when present (the `@soulcraft/cor` 3.0 acceleration layer) and fall
+>   back to pure-TS adjacency otherwise.
+> - **Additive ergonomics:** `add({ upsert: true })` (create-or-update in one call — merges into an
+>   existing id instead of overwriting), `find({ includeVectors: true })`, and `removeMany`'s batch
+>   size is now storage-adaptive (was a hardcoded 10).
+> - **Correctness fixes (apply to all consumers, not just graph users):** `related()` results now
+>   carry `visibility`; whole-graph/`getNouns` streaming no longer leaks `system`/`internal` entities;
+>   and small-page cursor walks over nouns no longer loop. No API change — just correct behavior.
