2. Core Patterns Identified

A. Autonomy Loop Pattern (MRAP - Monitor, Reason, Act, Reflect, Adapt)

Location: /tmp/daa/daa-orchestrator/src/autonomy.rs

pub enum AutonomyState {
    Initializing,
    Idle,
    Processing,
    Learning,
    Error(String),
    Stopped,
}

pub struct AutonomyLoop {
    config: AutonomyConfig,
    state: Arc<RwLock<AutonomyState>>,
    start_time: Option<Instant>,
    loop_handle: Option<tokio::task::JoinHandle<()>>,
    shutdown_signal: Arc<tokio::sync::Notify>,
}

Key Features:

• Continuous autonomous operation loop
• State management with RwLock for concurrent access
• Graceful shutdown via Notify signal

4. Reflect: Performance analysis
5. Adapt: Strategy refinement and learning

B. Emergent Consensus Protocol

Location: /tmp/daa/daa-swarm/memory/swarm-designer/protocols/03-emergent-consensus-protocol.rs

This is one of the most sophisticated patterns in the codebase - implementing consensus through emergent behaviors inspired by biological systems and chaos theory.

Key Concepts:

1. Opinion Landscape: Multi-dimensional space where agent opinions evolve

pub struct OpinionLandscape {
    pub dimensions: usize,
    pub expert_opinions: HashMap<String, OpinionVector>,
    pub potential_field: PotentialField,
    pub clusters: Vec<OpinionCluster>,
    pub topology: LandscapeTopology,
}

2. Attractor Basins: Stable regions that capture converging opinions

pub enum AttractorType {
    FixedPoint,
    LimitCycle,
    StrangeAttractor,
    Chaotic,
}

3. Phase Space Trajectories: Track opinion evolution over time

pub struct PhaseTrajectory {
    pub expert_id: String,
    pub positions: VecDeque<Vec<f64>>,
    pub velocities: VecDeque<Vec<f64>>,
    pub recurrence_map: RecurrenceMap,

    SecureAggregation,
    ByzantineFaultTolerant,
}
