THE ORACLE

Key Innovations

The Persona Engine: A custom RAG (Retrieval-Augmented Generation) system that remembers user history and "tags" their psychological state (e.g., [Anxious], [Skeptical]) to adapt the AI's tone and lethality.

Temporal Economy: Money is irrelevant. Time is the only currency. Users spend their "Lifespan" to consult the Oracle. A mechanical "Doom Clock" creates genuine tension, cutting the connection instantly when time runs out.

Sensory Immersion: A "Heavy Industrial" design language. Haptic feedback is triggered on every character typed by the AI, simulating a physical etching process.

Technical Stack

Core: React Native (Expo Managed Workflow)

Performance: React Native Reanimated 3 (Worklet-based 60FPS animations)

Storage: React Native MMKV (Synchronous, Encrypted local storage)

Styling: NativeWind v4 (TailwindCSS for Mobile)

State: Zustand + TanStack Query

Architectural Philosophy

"Zero-Spinner" Policy: Replaced standard loading states with diegetic "Meditation" animations to maintain immersion.

The "Know Thyself" Algorithm: Prioritizing long-term vector memory to create the illusion of omniscience.
