The open-core, Cortex-free half of the library A/B (handoff AJ/AK), authored once in brainy so the proprietary A/B comparison can import it for both legs: - tests/benchmarks/lib/corpus.js — deterministic clustered-mixture corpus generator (recompute-on-demand, O(clusters·dim) memory) for latency/ingest/memory at scale. - tests/benchmarks/lib/metrics.js — percentiles, brute-force recall@k, RSS snapshot. - tests/benchmarks/brainy-scale.js — brainy-alone scaling leg (ingest, find p50/p99 for vector/metadata/graph/triple, RSS). Recall is intentionally NOT measured on synthetic data — see below. - tests/unit/boundary-no-cortex.test.ts — CI guard: fails if @soulcraft/cortex ever appears in a src/ or tests/ import or in any package.json dependency field. - tests/integration/vector-recall.test.ts — semantic-search correctness on REAL embeddings (19-20/20 exact-text top-1). Methodology note: synthetic vectors (random/one-hot/clustered/latent) are near-orthogonal under cosine, so HNSW (any graph ANN, incl. DiskANN) cannot navigate them and recall collapses regardless of engine — a property of the data, not the index. Brainy vector search is verified correct on real embeddings. The A/B recall@10 column is therefore measured on SIFT/BIGANN, identically for both legs. |
