agentic-eval 0.14.2

//! Agentic-SWE benchmark for a **collaborative multi-agent system**.
//!
//! Scores a real collaborative multi-agent SWE round run over SPINE primitives
//! (`spine-mechgen --example collab_swe` in nervosys/SPINE): a builder + 3
//! reviewer agents executing a build → review → merge work-DAG, with
//! content-addressed signed artifacts, capability gating, and weighted
//! supermajority consensus. The inputs below are the **measured** metrics from
//! that run, scored on agentic-eval's four axes plus a multi-agent collaboration
//! coverage map.
//!
//! Measured (collab_swe): agents=4 tasks_done=3/3 consensus_decided=true
//! accepted=true artifact_signed=true deterministic=true gating_enforced=true
//! no_exec=true. spine-agentic 285 tests, spine-mechgen 5 tests green.
//!
//! Run: cargo run -p agentic-eval --example swe_multiagent
