Full detailed changelog: CHANGELOG.md.

[0.10.0] - 2026-06-26

Added

  • Released the v0.10 public surface set: QRNG streaming and FIPS/NIST health reports, ML-DSA-65/PQC trigger signing, UltraScale+ HLS pulse-source generation, NV-centre 20 T magnetometry simulation, FRC pulsed-shot QAOA scheduling, realtime loop telemetry, Studio federation manifests, and Kuramoto variant/acceleration routes.
  • Refreshed the API selector, tutorial routes, example gallery, new-module index, README, site home, reproducibility metadata, citation metadata, release-readiness scope, and generated capability manifests for the 0.10.0 package line.

Changed

  • Removed obsolete Paper 0 artifact requirements from the package release readiness gate after Paper 0 was intentionally extracted from this repository into the GOTM root register.
  • Kept hardware, RNG, cryptographic, HLS, realtime, and benchmark wording bound to existing evidence classes rather than promoting new hardware or production cryptographic claims.

[0.9.12] - 2026-06-15

Added

  • Public release metadata and documentation alignment for the current differentiable-programming hardening queue, including README, site home, onboarding, tutorial, notebook, API, reproducibility, hardware-ledger, release-readiness, citation, Zenodo, and generated capability inventory surfaces.
  • Adoption-oriented documentation routes explaining the software purpose, application lanes, commercial value, first user paths, notebook governance, API selection, evidence classes, and release-hygiene boundary without promoting unsupported hardware, clinical, or broad advantage claims.

Security

  • Updated the pinned CI pip package from 26.1.1 to 26.1.2 across the Python 3.10-3.13 lockfiles to remediate PYSEC-2026-196 / CVE-2026-8643.

Fixed

  • Hardened the internal TODO policy guard for exported source trees, including Docker images where .git is intentionally excluded, while preserving filesystem detection of competing TODO queues.

[0.9.11] - 2026-06-05

Added

  • Public documentation and release metadata alignment for the current differentiable-programming hardening state, including onboarding, tutorials, notebooks, API routes, reproducibility metadata, release-readiness scope, and generated capability inventory.
  • Native compiler-backed whole-program AD determinant support widened to verified static dense 6x6 through 19x19, with 20x20+ traces documented as fail-closed until a stronger determinant-partial helper is verified.

[0.9.10] - 2026-06-04

Added

  • Public documentation and release metadata polish for the current differentiable-programming implementation state, including onboarding, README positioning, tutorial and notebook routing, API boundary text, gradient evidence checklists, and the generated capability inventory.
  • Explicit enterprise-readiness boundary for supported parameter-shift, composed-objective, provider-gradient, transform-nesting, and compiler/program-AD routes, with unsupported arbitrary-program, hardware, and framework-native paths kept fail-closed.

[0.9.9] - 2026-06-02

Added

  • Public differentiable-programming documentation route covering quantum gradients, current compiler/program AD boundaries, public differentiable API entry points, notebooks, tutorials, planned framework adapters, benchmark evidence, and fail-closed unsupported scenarios.

[0.9.8] - 2026-06-01

Added

  • Public onboarding route covering project purpose, user routes, application lanes, commercial route, evidence boundaries, and release-documentation scope.
  • Refreshed first-path docs across README, documentation index, quickstart, tutorials, notebook guide, API overview, examples guide, installation guide, MkDocs navigation, and release-readiness page.

[0.9.6] - 2026-04-17

Changed (2026-04-29)

  • Added documented classical baseline surfaces for SciPy ODE, optional QuTiP Lindblad, and optional MPS TEBD runs.
  • Re-routed API documentation so stable facades are the first-path entry point and low-level module references sit under advanced navigation.
  • Added a mkdocstrings stable facades API page for first-path public facades.
  • Added a physics-first Kuramoto-XY tutorial with a tested arbitrary K_nm/omega workflow.
  • Refreshed README, docs index, and results gallery from the dated hardware status ledger.
  • Documented the licence boundary for a possible future lightweight Kuramoto-XY core package; no relicensing is implied.
  • Added a kuramoto_core facade for validated K_nm/omega problems, Hamiltonian/circuit compilation, dense Rust-backed Hamiltonians, and order-parameter measurement.
  • Added tools/check_dependency_drift.py so release checks can verify that requirements.txt still mirrors pyproject.toml.
  • QuantumKuramotoSolver validates coupling shape, finite values, symmetry, Trotter settings, and run-grid parameters before building circuits.
  • Added a public hardware status ledger that classifies theory, simulator, hardware, mitigated, and noise-limited claims and links visible docs to that evidence index.
  • requirements.txt mirrors the canonical runtime bounds from pyproject.toml; [all] is portable; CUDA/JAX packages live behind [accelerated]; CI includes a fresh editable [all] install smoke job.

Security

  • Bumped rand 0.9.2 → 0.9.4 (RUSTSEC-2026-0097).
  • Removed IBM Cloud CRN prefix log in scripts/retrieve_ibm_job.py.
  • Bumped pytest 9.0.2 → 9.0.3 (CVE-2025-71176).

Added

  • SCPNConfig via pydantic-settings ([config] extra) — unified runtime config.
  • structlog bootstrap ([logging] extra) — configure_logging + get_logger.
  • AsyncHardwareRunner — concurrent IBM submission over asyncio.
  • Plugin backends registry via entry_points group scpn_quantum_control.backends.
  • accel/ package — multi-language dispatcher with Rust → Julia → Python chain. [julia] extra adds juliacall-bridged order_parameter.
  • provenance.capture_provenance() — git hash + runtime + hostname on every result JSON.
  • Cross-validation test suite vs QuTiP + JAX/Dynamiqs ([xvalidate] extra).
  • Criterion Rust benches + GitHub workflow.
  • Issue triage policy (docs/triage.md), language policy (docs/language_policy.md).
  • docs/pipeline_performance.md §"Multi-language accel chain" with measured wall-times.

Changed

  • CI dev-tool matrix (pytest 9.0.3, mypy 1.20.1, ruff 0.15.10, hypothesis 6.151.13, build 1.4.3).
  • _order_param in hardware/classical.py now dispatches through the accel chain.
  • hardware/runner.py print() calls migrated to structured events.
  • HardwareRunner.DEFAULT_INSTANCE → _default_instance() reads SCPNConfig.

Repository hygiene

  • Public tracked files stripped of agent-name mentions; internal logs keep identity.
  • CHANGELOG.md terse-rewritten (dates + changes only, no attributions).
  • docs/contributing.md moved to private local workspace/ (gitignored).

[0.9.5] - 2026-03-29 / 2026-04-11

Phase 1 IBM raw-count observation of the DLA parity asymmetry + five strategic tweaks (GUESS, DynQ, ICI, hypergeometric, FFI hardening) + repository hygiene (gitleaks + custom secret scanner).

Phase 1 IBM ibm_kingston campaign (2026-04-10)

  • First publishable raw-count hardware observation of the DLA parity asymmetry on IBM ibm_kingston (Heron r2, 156 qubits). 342 circuits with up to 21 reps per (depth, sector) point at \(n = 4\). Mean asymmetry \(+10.8\,\%\) for Trotter depths \(\ge 4\), peak \(+17.48\,\%\) at depth 6. Welch's t-test 7/8 depths at \(p < 0.05\), Fisher's combined \(p \ll 10^{-16}\). Consistent with the \(4.5\text{–}9.6\,\%\) apriori simulator prediction.
  • Full statistical analysis script with error bars, Welch t-test, and matplotlib figures (scripts/analyse_phase1_dla_parity.py, figures/phase1/).
  • 267-line short-paper draft for Quantum Science and Technology / Physical Review Research in paper/.

Strategic tweaks from deep-research audit (2026-04-08)

  • GUESS symmetry-decay ZNE (mitigation/symmetry_decay.py, scpn_quantum_engine/src/symmetry_decay.rs) — physics-informed zero-noise extrapolation using \(\sum Z_i\) as the guide observable. Oliva del Moral et al., arXiv:2603.13060. 20 multi-angle tests.
  • DynQ topology-agnostic qubit mapper (hardware/qubit_mapper.py, scpn_quantum_engine/src/community.rs) — Louvain community detection on calibration-weighted QPU graphs. Liu et al., arXiv:2601.19635. 17 multi-angle tests.
  • PMP / ICI pulse sequences + (α,β)-hypergeometric pulse shaping (phase/pulse_shaping.py, scpn_quantum_engine/src/pulse_shaping.rs) — Liu et al. (2023) and Ventura Meinersen et al., arXiv:2504.08031. Rust paths give 44× hypergeometric envelope speedup and 1,665× ICI three-level evolution speedup, both verified to machine precision.
  • FFI boundary hardening — every #[pyfunction] returns PyResult<T> and validates inputs via validation.rs. 16 unit tests.
  • Long-form docs ≥ 567 lines: docs/symmetry_decay_guess.md (891) and docs/dynq_qubit_mapping.md (878).

Repository hygiene (2026-04-10)
