• #36375 accept integer distanceThreshold in nearestNeighbor YQL — coerces numeric annotation to double for ANN queries
• #36377 handle empty query stems safely in query-side stemming — drops empty-stem terms in AND/WeakAND contexts without collapsing the whole query
• #36380 expose custom annotations on compound query items (and, or, not, rank, weakAnd) — previously only leaf items supported annotations
