v3.6.1 Release Notes

Release Date: 2026-02-09

Highlights

Agent Teams Integration (ADR-064) delivers a hybrid fleet architecture layering Claude Code Agent Teams communication on the Queen Coordinator.

Added

  • Agent Teams Integration (ADR-064) — Hybrid fleet architecture with direct mailbox messaging, domain-scoped teams, and tiered fleet activation (Lite/Standard/Full)
  • Distributed Tracing — TraceContext propagation across agent messages via correlationId encoding. Queen traces task lifecycles end-to-end with span start/complete/fail
  • Competing Hypotheses — Multi-agent root cause investigation with evidence scoring and convergence. Auto-triggered on critical (P0/P1) task failures
  • Dynamic Agent Scaling — Workload-based auto-scaling integrated into Queen's metrics loop with configurable policies and cooldowns
  • Cross-Fleet Federation — FederationMailbox for multi-service routing with health monitoring and service discovery
  • Domain Circuit Breakers — Fault isolation per domain with configurable thresholds and automatic recovery
  • Task Dependency DAG — Topological ordering with cycle detection for complex multi-step workflows
  • HNSW Graph Construction — Real O(log n) HNSW insert/search replacing the O(n) stub in unified memory
  • Pattern Training Pipeline — TaskCompleted hook automatically extracts and trains patterns into ReasoningBank
  • Devils Advocate Agent — qe-devils-advocate for adversarial review of agent outputs

Fixed

  • 6 CodeQL alerts resolved in enterprise-integration services
  • TraceContext now correctly propagated through adapter sendMessage/broadcast
  • Dynamic scaler wired into Queen's metrics collection loop
  • Competing hypotheses auto-triggered on permanent P0/P1 failures

Changed

  • Queen Coordinator now manages trace contexts for all task lifecycles
  • Agent Teams adapter supports trace-aware messaging
  • Fleet tier descriptions updated for Lite/Standard/Full activation levels

Architecture

  • ADR-064: Agent Teams Integration — 4-phase hybrid architecture
    • Phase 1: Foundation (AgentTeamsAdapter, FederationMailbox)
    • Phase 2: Hybrid Architecture (CircuitBreaker, TaskDAG, DynamicScaler)
    • Phase 3: Learning Pipeline (ReasoningBankPatternStore, promotePattern)
    • Phase 4: Observability (DistributedTracing, CompetingHypotheses)

Test Coverage

  • 282 coordination tests passing
  • 397 total tests across 18 test files
  • 8 new tracing benchmark tests (all <500ms, typically <10ms)
