     - Candidates: `PType` integer kinds, buffer offsets, row indices, byte lengths
     - Goal: type-safety at zero cost (value class = no heap alloc, no boxing)
-- [ ] **Generalize `Array.limited(rows)` → `Array.slice(offset, length)`** — single verb, matches `MemorySegment.asSlice` / `ByteBuffer.slice` / `List.subList`; `limited(rows)` becomes `slice(0, rows)`.
-    - Zero-copy: buffer-backed (`Materialized*`, `length == elementCount`) slices the segment via `asSlice` (no per-element indirection); broadcast + view families fall back to `Offset*` wrappers
-    - Fold nested slices (`slice` of an `Offset*` composes offsets — never stack `Offset(Offset(...))`)
-    - Validate, fail fast (no silent clamp): consumer-facing `slice` throws `IllegalArgumentException` on `offset < 0 || length < 0 || offset + length > length()`; scan-internal `Offset*` construction fed by untrusted layout metadata throws `VortexException`
-    - Add the matching compact-constructor bounds guard to all `Offset*` records (currently document `inner length >= offset + length` but enforce nothing — broadcast inner silently wraps via `i % cap`)
