v0.3.3

Added

• StaticHierarchical topology (Topology::StaticHierarchical): eliminates the coordinator LLM call when routing is static. Swarms carry #[Topology(TopologyEnum::StaticHierarchical)], implement the new HasRoutePlan contract, and return a fixed route-plan array from plan(). Supports prompt(), run(), queue() (in_process), and stream(). dispatchDurable() is unsupported in v1 and throws before any infrastructure check fires.
  • Sequential worker nodes always stream live text deltas.
  • Parallel groups in stream() use concurrent mode by default (branches run via ConcurrencyManager; the sequential tail streams live) or sequential mode (each branch streams in declaration order). Controlled by #[StreamParallelBranches('concurrent'|'sequential')] on the swarm class, or the swarm.static_hierarchical.stream_parallel_branches config key (SWARM_STATIC_HIERARCHICAL_STREAM_PARALLEL_BRANCHES).
  • Same parallel groups, with_outputs named-output synthesis, DAG validation, and MaxAgentSteps enforcement as hierarchical. MaxAgentSteps counts worker nodes only — there is no coordinator step.
  • Swarm response and SwarmCompleted metadata include topology, route_plan_start, executed_node_ids, executed_agent_classes, parallel_groups, executed_steps, and execution_mode. coordinator_agent_class is intentionally absent.
  • Documentation: Static Hierarchical Topology.
