SONA WASM Bindings - Completion Summary

✅ Completed Tasks

1. Standalone Crate Structure

• ✓ Created /workspaces/ruvector/crates/sona/ directory
• ✓ Set up proper Cargo.toml with WASM support
• ✓ Configured cdylib and rlib crate types
• ✓ Added all necessary feature flags

2. Core Modules

• ✓ Copied all SONA modules from examples/ruvLLM/src/sona/:
  • types.rs - Core types and structures
  • lora.rs - Micro-LoRA and Base-LoRA implementations
  • trajectory.rs - Trajectory tracking and buffering
  • ewc.rs - Elastic Weight Consolidation (EWC++)

3. WASM Bindings (src/wasm.rs)

Created comprehensive JavaScript bindings:

• WasmSonaEngine wrapper class
