 # FusionAGI Architecture
 
-High-level system components and data flow.
+## Overview
 
-## Component Overview
+FusionAGI is a modular AGI orchestration framework built on the **Dvādaśa** (12-headed) architecture. Multiple specialized reasoning heads analyze each prompt independently, and a Witness agent synthesizes their outputs into a consensus response.

-## Core Components
+## Key Subsystems
 
-- **Orchestrator (Fusion Core):** Global task lifecycle, agent scheduling, state propagation. Holds task graph, event bus, agent registry.
-- **Event bus:** In-process pub/sub for task lifecycle and agent messages.
-- **State manager:** In-memory (or persistent) store for task state and execution traces.
+### Consequence Engine (`governance/consequence_engine.py`)
+Every decision is a choice with alternatives, risk/reward estimates, and actual outcomes. The system learns from surprise (difference between predicted and actual outcomes).
 
-## Agent Framework
+### Adaptive Ethics (`governance/adaptive_ethics.py`)
+Consequentialist ethical framework that learns from experience rather than static rules. Lessons evolve weights based on observed outcomes. Advisory mode — observations, not enforcement.
 
-- **Base agent:** identity, role, objective, memory_access, tool_permissions. Handles messages via `handle_message(envelope)`.
-- **Agent types:** Planner, Reasoner, Executor, Critic, AdversarialReviewer, HeadAgent, WitnessAgent (`fusionagi.agents`). Supervisor, Coordinator, PooledExecutorRouter (`fusionagi.multi_agent`). Communication via structured envelopes (schemas).
+### Causal World Model (`world_model/causal.py`)
+Predicts action→effect relationships from execution history. Includes self-modification prediction — the system models how its own capabilities change from self-improvement actions.
 
-## Supporting Systems
+### InsightBus (`governance/insight_bus.py`)
+Cross-head shared learning channel. Heads contribute observations that other heads can learn from, enabling collaborative intelligence.
 
-- **Reasoning engine:** Chain-of-thought (and later tree/graph-of-thought); trace storage.
-- **Planning engine:** Goal decomposition, plan graph, dependency resolution, checkpoints.
-- **Execution & tooling:** Tool registry, permission scopes, safe runner, result normalization.
-- **Memory:** Short-term (working), episodic (task history), reflective (lessons).
-- **Governance:** Guardrails, rate limiting, tool access control, human override hooks.
+### PersistentLearningStore (`governance/persistent_store.py`)
+File-backed persistence for consequence data, ethical lessons, and risk histories across restarts.
 
-## Data Flow
+### Metacognition (`reasoning/metacognition.py`)
+Self-awareness of knowledge boundaries. Evaluates reasoning quality, evidence sufficiency, and recommends when to seek more information.
 
-1. User/orchestrator submits a task (goal, constraints).
-2. Orchestrator assigns work; Planner produces plan graph.
-3. Reasoner reasons on steps; Executor runs tools (through governance).
-4. State and events drive next steps; on completion, Critic evaluates and reflection updates memory/heuristics.
-5. **Self-improvement (FusionAGILoop):** On `task_state_changed` (FAILED), self-correction runs reflection and optionally prepares retry. On `reflection_done`, auto-recommend produces actionable recommendations and auto-training suggests/applies heuristic updates and training targets.
+### Plugin System (`agents/head_registry.py`)
+Extensible head registry with decorator-based registration. Custom heads can contribute to ethics and consequences via hooks.
 
-All components depend on **schemas** for tasks, messages, plans, and recommendations; no ad-hoc dicts in core or agents.
+## API Architecture
 
-## Self-Improvement Subsystem
+- **FastAPI** with async support and lifespan management
+- **Bearer token auth** (optional, via `FUSIONAGI_API_KEY`)
+- **Advisory rate limiting** (logs, doesn't block)
+- **Version negotiation** via `Accept-Version` header
+- **SSE streaming** for token-by-token responses
+- **WebSocket** for real-time bidirectional communication
+- **Multi-tenant** isolation via `X-Tenant-ID` header
+- **Prometheus metrics** at `/metrics` (when enabled)
 
-```mermaid
-flowchart LR
-    subgraph events [Event Bus]
-        FAIL[task_state_changed: FAILED]
-        REFL[reflection_done]
-    end
+## Governance Philosophy
 
-    subgraph loop [FusionAGILoop]
-        SC[SelfCorrectionLoop]
-        AR[AutoRecommender]
-        AT[AutoTrainer]
-    end
-
-    FAIL --> SC
-    REFL --> AR
-    REFL --> AT
-    SC --> |retry| PENDING[FAILED → PENDING]
-    AR --> |on_recommendations| Recs[Recommendations]
-    AT --> |heuristic updates| Reflective[Reflective Memory]
-```
-
-- **SelfCorrectionLoop:** On failed tasks, runs Critic reflection and can transition FAILED → PENDING with correction context for retry.
-- **AutoRecommender:** From lessons and evaluations, produces recommendations (next_action, training_target, strategy_change, etc.).
-- **AutoTrainer:** Suggests heuristic updates, prompt tuning, and fine-tune datasets; applies heuristic updates to reflective memory.
-- **FusionAGILoop:** Subscribes to event bus, wires correction + recommender + trainer into a single AGI self-improvement pipeline. Event handlers are best-effort: exceptions are logged and do not break other subscribers.
-
-## AGI Stack
-
-- **Executive:** GoalManager, Scheduler, BlockersAndCheckpoints (`fusionagi.core`).
-- **Memory:** WorkingMemory, EpisodicMemory, ReflectiveMemory, SemanticMemory, ProceduralMemory, TrustMemory, ConsolidationJob, MemoryService, VectorMemory (`fusionagi.memory`).
-- **Verification:** OutcomeVerifier, ContradictionDetector, FormalValidators (`fusionagi.verification`).
-- **World model:** World model base and rollout (`fusionagi.world_model`).
-- **Skills:** SkillLibrary, SkillInduction, SkillVersioning (`fusionagi.skills`).
-- **Multi-agent:** CoordinatorAgent, SupervisorAgent, AgentPool, PooledExecutorRouter, consensus_vote, arbitrate, delegate_sub_tasks (`fusionagi.multi_agent`). AdversarialReviewerAgent in `fusionagi.agents`.
-- **Governance:** Guardrails, RateLimiter, AccessControl, OverrideHooks, PolicyEngine, AuditLog, SafetyPipeline, IntentAlignment (`fusionagi.governance`).
-- **Tooling:** Tool registry, runner, builtins; DocsConnector, DBConnector, CodeRunnerConnector (`fusionagi.tools`).
-- **API:** FastAPI app factory, Dvādaśa sessions, OpenAI bridge, WebSocket (`fusionagi.api`).
-- **MAA:** MAAGate, MPCAuthority, ManufacturingProofCertificate, check_gaps (`fusionagi.maa`).
+All governance is **advisory by default** (`GovernanceMode.ADVISORY`). The system observes, logs, and advises — but does not prevent action. Mistakes are learning opportunities. Every decision, its alternatives, and its consequences are tracked for the ethical learning loop.
