Walkthrough

The PR updates minimum Python support from 3.10 to 3.11, adds Python 3.14 support, removes Python 3.10-specific dependencies (tomli, numexpr), adjusts Gurobi constraints for Python 3.14 compatibility, and adds conditional test skipping based on Gurobi availability.

Changes

Cohort / File(s)	Summary
Python version support pyproject.toml, .github/workflows/tests.yaml	Updated test matrix and minimum Python requirement from 3.10 to 3.11; added Python 3.14 to classifiers; removed 3.10 classifier
Dependency updates pyproject.toml	Removed tomli and numexpr (Python 3.10-specific); updated gurobipy constraints to >= 10.0.0, < 14 with Python 3.14 gating; updated scipy to 1.16.3 for Python < 3.14 compatibility
Tooling configuration pyproject.toml	Updated Ruff target-version from py310 to py311
Test infrastructure tests/test_scenarios.py, tests/deprecated/test_scenarios.py	Added Gurobi availability detection via importlib.util.find_spec(); added @pytest.mark.skipif() decorators to skip tests when Gurobi not installed

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~10 minutes

• Verify gurobipy and scipy version constraints are correct for Python 3.14
• Confirm Gurobi availability detection pattern is consistent across both test files
• Ensure test skipping doesn't mask real failures on systems without Gurobi

Poem

🐰 From 3.10 to 3.11, we hop ahead with glee,
Python 3.14 joins the party—let's see what's to be!
Gurobi gates and versions align,
Dependencies pruned, the support so fine,
A leap to the future, both graceful and clean! 🌟

🔇 Additional comments (14)

tests/test_scenarios.py (4)

1-2: LGTM!

The import of importlib.util is appropriate for runtime package detection.

---

16-17: LGTM!

The GUROBI_AVAILABLE flag correctly detects gurobipy availability at runtime using importlib.util.find_spec. This pattern enables graceful test skipping when Gurobi is not installed, which is particularly relevant for Python 3.14 where gurobipy wheels are not yet available.

---

296-296: LGTM!

The skip decorator properly guards the Gurobi-dependent test, allowing the test suite to run on environments without Gurobi (including Python 3.14).

---

333-333: LGTM!

The skip decorator properly guards the Gurobi-dependent test, consistent with the pattern used elsewhere in the file.

tests/deprecated/test_scenarios.py (4)

1-2: LGTM!

Consistent with the changes in tests/test_scenarios.py.

---

16-17: LGTM!

The GUROBI_AVAILABLE flag implementation mirrors the pattern in tests/test_scenarios.py, providing consistent runtime detection across test modules.

---

296-296: LGTM!

Consistent with the skip decorator pattern in tests/test_scenarios.py.

---

333-333: LGTM!

Consistent with the skip decorator pattern applied throughout the test files.

pyproject.toml (5)

10-10: LGTM!

The minimum Python version requirement has been correctly updated to 3.11, aligning with the PR objectives.

---

28-28: LGTM!

The Python 3.14 classifier has been added appropriately.

---

134-134: LGTM!

The ruff target-version has been correctly updated to py311 to match the new minimum Python version.

---

86-87: Verification confirms scipy 1.16.3 and gurobipy 12.0.3 are pinned correctly for Python 3.14 support.

Scipy 1.16.3 does provide Python 3.14 wheels (cp314), confirming the requirement stated in the comment. Gurobipy 12.0.3 has wheels only through Python 3.13 (cp313), confirming that the python_version < '3.14' constraint is necessary and the "No Python 3.14 wheels yet" comment is accurate.

---

68-68: The version constraint and timeline comment are accurate. Gurobi officially plans Python 3.14 wheel support in version 13.0.1, scheduled for Q1 2026. The constraint correctly gates gurobipy for Python versions below 3.14, and the comment correctly notes that wheels are not yet available.

.github/workflows/tests.yaml (1)

48-48: Python 3.14 is supported and available — no action needed.

actions/setup-python@v6 fully supports Python 3.14 on ubuntu-24.04. Python 3.14 reached final release on October 7, 2025 (current maintenance release: 3.14.2), and the action can resolve and install it correctly.
