Baseline refresh — 2026-06-10.

First eval after the embed pool grew from 2 ripper Ollamas to 4 endpoints
(+ .0.125 RTX 4090, + .0.126) and rag/embeddings.py gained endpoint
rotation/split resilience (PR #8, port of zerto-docs PR #45). Run against
the chroma/bm25 indexes extracted from the prod image built by today's
image-only run (post-merge rebuild on the 4-endpoint pool); query embeds
via host Ollama :11434, reranker = the prod jina-rerank instance.

vs the 2026-05-22 baseline.md: bm25+rerank MRR 0.920→0.959,
hybrid_rrf+rerank 0.875→0.960 — no regression from the mixed-provenance
embeddings (zerto-docs ran a same-corpus ripper-only control to verify
this property of the shared pool; see zerto eval/results/control-20260610.md).
