strided-basic

Shared typed CPU primitives and concrete copy, concatenation and reduction execution. Generic map/zip, SIMD, indexing plans and their validation stay with the traversal implementation. Concrete ordinary arithmetic/indexing dispatch lives in strided-kernel; runtime-DAG fusion lives in strided-fused. Neither of those packages is a dependency of this crate.

use strided_basic::{copy_into, StridedArray};
let src = StridedArray::<f64>::from_fn_col_major(&[2, 3], |i| (i[0] + 2*i[1]) as f64);
let mut dst = StridedArray::<f64>::col_major(&[2, 3]);
copy_into(&mut dst.view_mut(), &src.view()).unwrap();
assert_eq!(dst.get(&[1, 2]), 5.0);

copy_into_uninit copies into StridedViewMut<MaybeUninit<T>> without first initializing the destination. Success initializes every logical element, not unreachable holes. It preserves the shared bounded-thread policy.

simd is enabled by default. parallel opts into the shared execution policy; ExecContext::serial() requests the serial path. Features select implementation capabilities, not operation families.

The execution module is a documented low-level kernel-extension contract. Prevalidated entry points are unsafe, and a layout marker alone does not satisfy their requirements. Application code should use the checked root APIs.
