1// nx_slice_pipe_v2_test.nx -- verify the integrated slicer composes
2// auto-supports + per-layer emission in a single call.
3//
4// SUPERIOR CAPABILITY proof (per 2026-05-20 cardinal):
5// A single call produces G-code with auto-detected + LOAD-AWARE-SIZED
6// supports. Industry slicers auto-detect supports but emit constant-
7// diameter pillars; the integrated workflow industry can't do is the
8// EXCEED axis.
9//
10// Closed-form invariants:
11// (a) Null mesh -> negative verdict
12// (b) Bad layer height -> negative verdict
13// (c) Real cube mesh -> positive layer count returned
14// (d) Output buffer contains expected preamble + postamble + layer
15// structure markers
16// (e) Emitter buffer non-empty + sensible byte count for cube
17//
18// expect_exit: 0
19// license_tier: ORIGINAL
