Variable EDGE_KINDSConst

Edge kind in the typed-network graph. Each kind carries a different spreading-activation multiplier μ(ℓ) per Hindsight Eq. 12 (§2.4.1).

• temporal: connects facts that share an occurrence-interval overlap. Weight derived from exp(−Δt / σt).
• semantic: connects facts whose embeddings exceed a cosine threshold θs.
• entity: bidirectional link between facts mentioning the same named entity. Weight 1.0.
• causal: explicit reasoning marker linking premise → conclusion facts. LLM-extracted at observation time; weight 1.0.
