1//! Agent group types for oxios orchestration.
2//!
3//! oxios has its own `OxiosAgentGroup` struct for managing groups of agents
4//! spawned by the orchestrator (Seed splitting, state persistence, events).
5//!
6//! For multi-agent execution within a pipeline/parallel/orchestrated workflow,
7//! use the re-exports from oxi_sdk: `SdkAgentGroup`, `SdkGroupResult`.
8//! See `lib.rs` for oxi-sdk re-exports.
