Exact-Root Certification of Finite-Error Ordering in Quantum Control

This release closes the open-system ordering-survival stress-audit layer for the frozen exact-root ordering result.

Validated results:

• 29 open-system Lindblad stress conditions were evaluated.
• 2088/2088 density-matrix propagations completed with finite values.
• The no-dissipation/unitary limit reconstructed the frozen ordering with Spearman rho = 1.0, complete ordering preserved, and 66/66 certified pair directions preserved.
• At integrated severity 0.01, the predeclared empirical gates passed for decay, dephasing, and joint decay+dephasing conditions.
• Across the declared stress grid, 55/66 path pairs never flipped.
• Across the declared stress grid, 11/66 path pairs flipped at least once.
• The complete machine report attached to this release has SHA-256 25ec3da765afa91b90d3d37d5d89298001821253b5f5be6f8482834e92703bf8.

Scope: This is a local QuTiP Lindblad open-system model stress test. It is not an Arb interval proof, not a calibrated PASQAL hardware-noise model, and not PASQAL Cloud, FRESNEL, or physical QPU evidence.

The field prospective_freeze_verified_by_expected_hash=true means that this CI recomputation was constrained by the already committed protocol hash. It does not make the original differential dissipative-susceptibility interpretation a preregistered prediction; that mechanism remains a post-hoc v1.1 follow-up hypothesis.
