1// nx_install_pipeline_test.nx -- smoke for the SA arc end-to-end
2// orchestrator nx_install_pipeline_run_with_inputs.
3//
4// Exercises:
5// 1. BAD_INPUT gates (null probe / calib / policy / nodes / out)
6// 2. Successful 3-node chain produces VALID plan + 32-byte hash
7// that matches direct (capture + hash) recomputation
8// 3. End-to-end REPRODUCIBILITY: same inputs -> bit-equal install_hash
9// 4. End-to-end SENSITIVITY: change probe.page_size -> different hash
10// 5. SELECT_FAILED path: no-feasible-chain produces
11// NX_PIPELINE_SELECT_FAILED with zero'd install_hash + plan
12// carrying NX_PLAN_VERDICT_NO_FEASIBLE
13// 6. Sealed-enum validity gate
14//
15// This is the LOAD-BEARING end-to-end gate for the SA arc: it proves
16// the chain (probe + calibration + policy + workload-DAG) -> single
17// install_hash works as a pure composition, and that the hash is
18// both reproducible and sensitive to content.
