Chapp-E Developer Documentation
Complete reference for Chapp-E Neural OS v0.1.0
Core Philosophy
Understanding the fundamental driving force: from neural tube/DNA blueprint to living, conscious system.
- Neural Tube = Bootloader (origin structure)
- DNA = Assembly code (architectural blueprint)
- Driving Force = Message loop (dynamic network activity)
- Consciousness emerges from integrated system interactions
- The blueprint "coming to life" through moment-to-moment activity
Brain Controller
The central kernel hub that coordinates all neural subsystems using message-based communication.
- Message queue system for inter-subsystem communication
- State management (INIT, READY, PROCESSING, SLEEP)
- 64-bit long mode architecture
- VGA text mode output
- Subsystem initialization and coordination
Consciousness System
Neural network component tracking awareness states and consciousness levels.
- AWAKE, SLEEP, UNCONSCIOUS states
- State transitions and persistence
- Integration with Brain Controller
- 64-bit implementation
- Memory-mapped state storage
Shell System
Interactive command-line interface with PS/2 keyboard input and VGA output.
- PS/2 keyboard scancode handling
- Command parsing and execution
- Built-in commands: help, clear, echo
- Screen scrolling support
- Formatted output with colors
Command System
Comprehensive command-line interface for all Chapp-E operations - OS, neural networks, brain systems, chemicals, and DAG-FS.
- OS Commands: help, clear, echo, info
- Neural Network: neuron, weight, network operations
- Brain System: consciousness, state, memory management
- Memory Commands: hippocampus, encode, consolidate, retrieve
- Chemical/Neuromodulator: chem, mod, bbb operations
- DAG-FS: dag, pattern, tag operations
- Extensible command table system
- Argument parsing and execution framework
FSM System
Finite State Machine for input handling and state management.
- READY, TYPING, PROCESSING states
- Character input buffering
- State transition logic
- Backspace handling
- Integration with shell input
GCS System
Garbage Collection System for input filtering and noise reduction.
- Input character filtering
- Noise reduction algorithms
- Buffer management
- Integration with FSM
- Memory-efficient processing
Executive Control
Goal-directed behavior layer with multi-slot working memory and multi-step planning.
- Working Memory: 3 slots × 64 bytes with priority management
- Planning System: Up to 8 steps per plan with goal storage
- State tracking: IDLE, ACTIVE, OVERLOADED, PLANNING, EXECUTING
- Memory address: 0x200000 (safe region)
- Full Brain Controller integration
Neuromodulator System
Synthetic neurochemistry layer with regional distribution, BBB filtering, and glymphatic clearance.
- 6 neuromodulators: Dopamine, Serotonin, Acetylcholine, Cortisol, Noradrenaline, Oxytocin
- Regional distribution across 6 brain regions
- Blood-Brain Barrier: Selective input filtering
- Glymphatic clearance during SLEEP state
- Volume transmission: Chemical diffusion between regions
- Dynamic mood states based on chemical levels
DAG-FS Filesystem
Complete brain-inspired filesystem storing "files" as distributed patterns of synaptic weights. ALL 5 PHASES IMPLEMENTED.
- ✅ Pattern storage: Files = weight configurations (1024 patterns)
- ✅ Pattern reconstruction: Forward pass rebuilds patterns
- ✅ Tag system: 512 tags, contextual querying
- ✅ Pattern completion: Partial input → full reconstruction
- ✅ Hebbian learning: Weight updates on access
- ✅ Reconsolidation: Every read strengthens pattern
- ✅ Long-Term Depression: Delete weakens weights (forgetting)
- ✅ Pattern association: Link patterns together
Multiboot Bootloader
64-bit boot system using Multiboot2 specification and GRUB.
- Multiboot2 compliant header
- 32-bit to 64-bit transition
- Page table setup for long mode
- GRUB integration
- ELF binary format

Note: Chapp-E is a neural operating system inspired by brain architecture. The kernel (Brain Controller) coordinates all subsystems through message-based communication, similar to how the brain's central nervous system coordinates body functions. All systems are implemented in pure x86-64 assembly.
