+# ADR-003: Consequence Engine for Ethical Learning
+
+## Status
+Accepted
+
+## Context
+Traditional AI ethics systems use static rules (constitutional AI, RLHF reward models). FusionAGI needed a system that could learn ethical behavior from experience — understanding that every choice carries consequences and that risk/reward assessment improves with data.
+
+## Decision
+Implemented a **ConsequenceEngine** that:
+1. Records every choice the system makes (action + alternatives considered)
+2. Estimates risk and reward before acting
+3. Records actual outcomes after execution
+4. Computes "surprise factor" (prediction error)
+5. Feeds into AdaptiveEthics for lesson generation
+6. Uses adaptive risk memory window that grows with experience
+
+The weight system for ethical lessons is **unclamped** — extreme outcomes can push lesson weights below 0 (strong negative signal) or above 1.
+
+## Consequences
+- The system develops genuine experiential ethics rather than rule-following
+- Early-stage behavior may be more exploratory (higher risk)
+- All consequence records are persisted via PersistentLearningStore
+- Cross-head learning via InsightBus amplifies ethical insights
+- The SelfModel's values evolve based on consequence feedback
+
+## Alternatives Considered
+1. **RLHF-style reward model** — Rejected: requires human feedback loop, doesn't scale
+2. **Constitutional AI** — Rejected: static rules, doesn't learn
+3. **No ethics system** — Rejected: need accountability and learning signal
