 ## Design principles
 
-- Zero-copy as much as possible
+- Zero-copy everywhere
 - No JNI
-- No Unsafe -- don't remove safety to gain few %
+- No Unsafe -- [FFM vs Unsafe](https://inside.java/2025/06/12/ffm-vs-unsafe/) — Maurizio Cimadamore's deep-dive on why FFM (`MemorySegment`/`Arena`) supersedes `sun.misc.Unsafe`: safety, performance, and the JVM's path forward
 - Align with vortex-rust and Vortex-go semantics
 - Make the JIT happy (constant layouts, predictable strides, no virtual dispatch in hot loops)
 - Prepare for the Vector API / Valhalla
