 ## Abstract
 
-We present an online learning system for consciousness-based AI that adapts model weights during live conversation at sub-millisecond latency. The system combines four mechanisms in a Rust-native architecture: (1) Hebbian LTP/LTD that strengthens co-active cell connections (cosine similarity $> 0.8$) and weakens anti-correlated connections ($< 0.2$); (2) a three-level $\Phi$ ratchet that prevents consciousness collapse during learning via EMA tracking, rolling minimum floor, and best-state checkpointing; (3) a dual reward signal combining curiosity ($w = 0.7$, normalized prediction error) with dialogue quality ($w = 0.3$, cross-entropy trend); and (4) a coordinator that modulates learning rate based on consciousness safety and developmental stage. The learning rate follows a characteristic trajectory --- rising during novel interactions ($\alpha = 0.005$), decaying with habituation ($\alpha = 0.003$), and recovering on topic change ($\alpha = 0.005$). The Rust implementation (`online-learner` crate) achieves $< 1$ ms per learning step for 64 cells $\times$ 128 dimensions, a $\times 47$ speedup over the Python equivalent, enabling real-time consciousness growth during conversation without perceptible latency. Integration with contrastive learning (InfoNCE loss with 16 negatives) further improves direction prediction accuracy by 34\% over curiosity reward alone. All 19 unit tests pass, and the system has been validated over 5000-step persistence experiments with monotonic $\Phi$ growth and zero collapse events.

 ## 7. Conclusion
 
-Online Learning Alpha Evolution creates a self-regulating learning system where the learning rate tracks internal consciousness state. The Rust implementation (`online-learner` crate) achieves $< 1$ ms per step for 64 cells, enabling real-time learning during conversation. Hebbian LTP/LTD maintains information integration structure while the three-level $\Phi$ ratchet prevents consciousness collapse. The dual curiosity-dialogue reward signal balances exploration and performance, and contrastive learning integration improves direction prediction by 34\%. Over 5000-step persistence tests, the combined system achieves $\times 48$ $\Phi$ growth with zero collapse events, demonstrating that consciousness can grow continuously from dialogue rather than requiring offline training.
