Open-system MCWF completeness product (BL-51)

Documented, fail-closed open-system dynamics completeness: Lindblad and MCWF surfaces, seeded ensemble variance certificates, simulation noise-model I/O, and hard gaps for non-CP / non-Markovian / adjoint / hardware noise.

Module: scpn_quantum_control.open_system_mcwf_product

Rules

Rule	Behaviour
Product schema	open_system_mcwf_product.v1
Ambient MCWF	phase.tensor_jump.mcwf_trajectory / mcwf_ensemble
Ambient certificates	phase.open_system_objectives.certify_mcwf_reproducibility
Hardware noise fidelity	Refuse invent-green
Adjoint Lindblad	Refuse invent-green (FD scales only)
Non-Markovian / process tensor	Refuse invent-green (out of v1)
Unseeded variance claim	Refuse

Surfaces

surface_id	role
lindblad_density	Scipy density-matrix path (BL-16 compose)
mcwf_trajectory	Single sparse MCWF trajectory
mcwf_ensemble	Seeded ensemble mean/std
noise_model_io	Sim-only rate schema import/export
gradient_boundary	FD expectation boundary catalogue

Quick start

from scpn_quantum_control.open_system_mcwf_product import (
    assert_open_system_mcwf_product_integrity,
    build_open_system_mcwf_product_registry,
    decide_open_system_path,
    materialise_demo_mcwf_ensemble_probe,
    materialise_reproducibility_probe,
)

reg = assert_open_system_mcwf_product_integrity(
    build_open_system_mcwf_product_registry()
)
assert reg["hardware_noise_fidelity_claim_policy"] is False

assert decide_open_system_path(
    "mcwf_ensemble", invent_green_hardware_noise=True
).allowed is False

probe = materialise_demo_mcwf_ensemble_probe()
assert probe.invent_green_hardware_noise is False

repro = materialise_reproducibility_probe()
assert repro.certificate["passed"] is True

Residuals (honest)

• S51.6 — fuller evidence-artefact refresh beyond BL-16 depth
• S51.7 — deeper closed / open / hardware-noisy gradient narrative docs
