+/* ── Associative leg (claim 10 typed relations + claim 1 activation) ────────
+ *
+ * WHY THIS EXISTS. engram_search_json has two legs, and neither can reach a
+ * node that shares no token with the query and no embedding neighbourhood
+ * with it. The route the design reserves for that case is the graph: a node
+ * is reachable because it is STRUCTURALLY associated with something the query
+ * did hit. Nothing on the recall path consults an edge today.
+ *
+ * WHY NOT engram_activate. Wiring recall wholesale to activation was measured
+ * (PR #135) and lost 57 points of phrase accuracy. The failure was one of
+ * RANK, not reach: activation seeds on every token-matching node, so a 2-hop
+ * associate at strength ~0.06 never outranks thousands of 1-hop neighbours of
+ * strong lexical seeds. So this is a separate, small, ranked list that is
+ * merged BESIDE the other two, exactly as the semantic leg is.
+ *
+ * TYPED RELATIONS (06-claims.md claim 10). Expansion follows only relations
+ * that assert a structural claim about meaning. The corpus is 4,915 `tagged`
+ * and 3,767 `triggers-safety` edges against 475 `identity` and 11 `contains`;
+ * walking the bulk relations turns any seed into a flood (measured: 1,387
+ * candidates from one seed) while the structural ones stay in the low tens.
+ * This is the first code on the read path to branch on a relation type at all.
+ *
+ * DIRECTION. Edges are walked in BOTH directions. Claim 23 requires the store
+ * to keep reverse edge records keyed by target id, and the adjacency index
+ * already materialises them (adj_to). It has to be both: every value node in
+ * this corpus has exactly ONE inbound edge (hub -> value) and no outbound
+ * structural edge at all, so a forward-only walk from a value node reaches
+ * nothing. Note this is an extension of the traversal as literally specified
+ * (05-detailed-description l.66 says "all outgoing edges"); the reverse index
+ * is designed and stored, but the description does not say the walk reads it.
