self-review 2026-05-20: relation-type boost in BFS propagation
Add relation-specific multipliers to spreading activation:
- causes/caused_by edges: 2.0× (causal reasoning propagates stronger)
- enables/prevents edges: 1.5× (conditional logic gets boost)
- supersedes edges: 1.3× (promoted knowledge gets slight priority)
- inferred A→C edges: 0.7× (traversal-inferred paths weaker than explicit)
Field-validated against Hindsight (time-aware spreading activation, 2026)
and ACT-R cognitive architecture literature. Inferred edge discount prevents
the traversal inference pass from flooding activation with spurious high-
strength paths equal to explicit links.
