NPU-Native Synaptogenesis - Zero-Copy Morphology Application

This module re-exports core morphology implementations from the core_morphologies module for backward compatibility. All core morphologies have been refactored into separate modules in the core_morphologies directory.

§Architecture

Python: Call rust_apply_projector(npu, src_area_id, dst_area_id, params)
           ↓
Rust:   1. Query neurons from NPU (zero copy)
        2. Apply morphology rules (SIMD optimized)
        3. Create synapses directly in NPU
        4. Return synapse count
           ↓
Python: Receives u32 (synapse count only)

§Performance Impact

  • Eliminates: 6+ seconds of FFI overhead per area pair
  • Eliminates: Python list building and marshaling
  • Enables: SIMD-optimized morphology application
  • Result: ~50+ second improvement for typical genomes
