-// auto_link_content_node — link a newly-created Knowledge or Memory node to
-// semantically related non-ISE nodes via BM25 search.
-//
-// Problem it solves: route_neuron_memory and route_neuron_knowledge_capture
-// both call engram_node_full directly, creating nodes with zero edges. With
-// 14K+ ISEs dominating the corpus, BFS traversal contributes nothing — every
-// query relies solely on lexical/semantic seed matching. Auto-linking builds
-// explicit "related" edges so activated knowledge nodes fan out to connected
-// neighbors during BFS.
-//
-// Design choices:
-//   - BM25 (not substring search): ranks by relevance, not just occurrence
-//   - Skip InternalStateEvent nodes: ISEs dominate the corpus and are not
-//     useful link targets for knowledge/memory nodes
-//   - Up to 3 edges per node: enough to build graph structure without over-linking
-//   - weight=0.6: moderately strong; causal edges (field-validated at 2.0) are
-//     much stronger, so these "related" edges don't flood activation paths
-//   - state_set for linked counter: EL `let` in nested if-blocks creates inner
-//     scope only; state_set persists across block boundaries (2026-05-25 lesson)

+ *   - dlsym    : el_runtime.c uses dlsym(RTLD_DEFAULT, name) to resolve callback/tool symbols
+ *                exported by the main module. Windows equivalent: GetProcAddress on the process
