june-bench 0.0.4

Reproducible benchmark suite for memory/QA systems — June + pluggable competitors.

june-bench

A pip-installable, reproducible benchmark suite for memory / QA systems — June + pluggable competitors — over LoCoMo, LongMemEval, HotpotQA/2Wiki/MuSiQue, and FinanceBench, with the same data and the same scorer.

A benchmark is run(system, dataset) → records → score. Two typed ports are the only extension points:

• System — the thing benchmarked. JuneApiSystem (default; a thin HTTP client to June's /v1/answer, so no June source is shipped), JuneLocalSystem ([june-local] extra; a source-protected compiled wheel), CogneeSystem ([cognee] extra), or any future system as one adapter.
• Dataset — what it runs on. The four benchmarks behind a registry.

The scorer is the canonical SQuAD/HotpotQA EM/F1 + selective-accuracy/coverage/cost — Cognee-comparable. Tiny smoke fixtures ship in the wheel (offline wiring proof); full splits are fetched, sha-verified, from a pinned release. No score is ever baked into the package — every result row records dataset + scorer + system + model + cost, so a published number is reproducible by a stranger.

Status: SB0 (contracts + no-deps smoke + skeleton). Datasets, June/Cognee systems, and the full CLI land in SB1–SB6.
