Defined in: packages/memory/src/tiers/semantic-memory.ts:88

Score-fusion strategy for SemanticMemory.search (X-2).

• 'rrf' (the default when fusion is omitted) fuses the candidate lists through the configured reranker — the zero-tuning RRFReranker unless one was overridden.
• 'weighted' fuses through WeightedRRFReranker, scaling each list's reciprocal-rank contribution by its FusionWeights, for callers who have calibrated retriever reliability against labels (the P0-1 eval harness). At equal weights it reproduces RRF.
