+ * Entity Associations — pure similarity-scoring engine.
+ *
+ * Two entities in the knowledge graph are "associated" when they share many of
+ * the same connections — e.g. two people who know all the same people, or two
+ * projects that touch the same systems. This is captured by the Jaccard
+ * similarity of their (undirected) neighbour sets:
+ *
+ *   jaccard(a, b) = |N(a) ∩ N(b)| / |N(a) ∪ N(b)|
+ *
+ * The valuable case is a HIGH-similarity pair that is NOT directly linked: the
+ * graph already "knows" they belong together (shared context) even though no
+ * single triple connects them — a relationship a direct-edge view never shows.
+ *
+ * Everything here is PURE and DETERMINISTIC: no React, no RPC, no clock, no
+ * randomness. Output depends only on the (subject, object) structure, never on
+ * insertion order, so the same graph always yields identical rankings.
+ *
+ * Direction is ignored for neighbourhoods (an association is symmetric) and
+ * self-loops are dropped (a node is not its own neighbour). Entity identity is
+ * the raw string AS-IS (no trimming / case-folding), consistent with the other
+ * graph lenses. Pair keys are canonical JSON (smaller id first), so entities
+ * containing any character can never collide.
