Bilingual embedding bench

tnsai-evaluation ships an opt-in multilingual retrieval bench (EmbeddingBenchRunner, @since 0.14.0 on TnsAI@c28d8783). It is in Maven Central 0.14.1. Default mvn test stays offline and does not call a model host.

This harness does not change the production hash embedding default.

Run

Requires a local Ollama daemon and:

ollama pull qllama/multilingual-e5-small
ollama pull bge-m3
mvn -pl tnsai-evaluation -am -Pembedding-bench test

The live IT is gated by @EnabledIfSystemProperty(embedding.bench=true), which the embedding-bench Maven profile sets. Override the host with OLLAMA_BASE_URL (default http://localhost:11434).

EmbeddingBenchRecommendation always reports production default hash (unchanged). An installable default is recommended only from measured scores; this ticket does not ship a process-wide model.

Measured table

One dated local-Ollama run lives in the framework tree:

Re-run the profile to refresh target/embedding-bench-results.md. Do not treat a single laptop run as a universal ranking.
