Features

1 · Thread-per-core

One executor per core, pinned. No global scheduler, no work-stealing.

2 · No atomics

One owner per value. Wakers are Cell / UnsafeCell; o3’s shared refcount is a Cell<u32>, not an Arc.

3 · No dyn dispatch

Manifolds route by a const ID match, decoders are fn pointers, routers are generated code. A workspace grep for dyn returns zero.

4 · No shared state

No Arc, Mutex, RwLock, or cross-core channel — each core owns its slab and waker arena outright.
