engram_wm_count() exists and counts nodes with working_memory_weight > 0. emit_heartbeat() and proactive_curiosity() were both calling engram_node_count() (total graph size: ~17K) instead — every heartbeat and curiosity_scan ISE had been reporting wm_active=17769 since the graph grew past ~3K nodes, making the metric meaningless for observability. Fix: use engram_wm_count() for the wm_active field in both ISE payloads.
