# Embeddenator Interop - Development Context

## Active Technologies
- **Rust**: Stable toolchain (edition 2021)
- **Kernel Integration**: System-level interop for holographic filesystem operations
- **Dependencies**: embeddenator-vsa (VSA primitives), embeddenator-fs (FUSE filesystem)
- **Testing**: proptest for property-based testing

## Project Structure
```
embeddenator-interop/
├── src/
│   └── lib.rs           # Kernel interop and system integration logic
├── tests/               # Integration tests
├── Cargo.toml           # v0.20.0-alpha.1
└── README.md            # Phase 2A component extraction status
```

## Commands
- **Build**: `cargo build --release`
- **Test**: `cargo test`
- **Check**: `cargo clippy --all-targets`
- **Format**: `cargo fmt --all`

## Code Conventions
- **System Integration**: Provide abstractions for kernel-level operations (mmap, page cache, etc.)
- **FUSE Bridge**: Integrate with embeddenator-fs for filesystem mounting
- **Platform Compatibility**: Use conditional compilation (`#[cfg(target_os = "...")]`) for OS-specific code
- **Error Handling**: Wrap system errors in descriptive Rust error types
- **Safety**: Minimize unsafe blocks; document invariants when required

## Current Focus
- **Phase 2A Component Extraction**: Interop logic extracted from embeddenator monorepo
- **Kernel Integration**: System-level abstractions for holographic filesystem operations
- **FUSE Filesystem Bridge**: Connect embeddenator-fs to OS kernel via FUSE protocol
- **Platform Support**: Validate functionality on Linux/macOS/BSD
- **Performance**: Optimize system call overhead and memory mapping strategies

## Recent Changes
- Extracted from embeddenator monorepo as standalone interop component crate
- Defined clean API boundaries between user-space and kernel-space operations
- Version bumped to 0.20.0-alpha.1
- Integrated with embeddenator-vsa and embeddenator-fs
- Added platform-specific conditional compilation

## Agents
- Embeddenator Agent (`embeddenator/.github/agents/embeddenator.agent.md`): VSA/engram/Rust integration expert
- Interop Agent (TBD): Kernel integration and system programming
