A clean wheel currently includes only the top-level moha modules, so importing the installed package outside the checkout raises ModuleNotFoundError: No module named 'moha.rauk'.

Discover the moha subpackages and include their JSON/TOML runtime resources. Add a CI smoke check that installs the built wheel into an isolated target, imports it outside the checkout, and verifies the six runtime data files.

Validation:

• A clean source archive of e27c5b9 produced a wheel without moha.rauk and failed the isolated import; the fixed wheel imports successfully and contains all six runtime resources.
• python -m pytest -q moha/test: 9 passed, with SparseEfficiencyWarnings.
• git diff --check and pycodestyle moha/: passed.
• pydocstyle moha/: existing D205/D207/D400 errors in the HamHeisenberg docstring. The pre-commit bot removed its trailing whitespace; this PR changes no Python runtime logic.

Hi @RichRick1 and @giovanni-br, I opened this after reproducing the missing package files from a clean wheel install. The isolated wheel smoke test and package tests are passing. Could you let me know whether this fix is in the right direction or needs any changes? I am keen to keep contributing to ModelHamiltonian and would appreciate a pointer to the next useful issue after this one.

🟢 Approval recommended

The packaging changes address the reported failure, the smoke check covers imports and required resources, and no blocking issues remain.

No open issues 🎉

What changed in this PR

Fixes wheel packaging so installed moha includes its subpackages and runtime resources, resolving imports that fail outside the checkout.

Changes:

• Enables subpackage discovery and includes JSON/TOML runtime data.
• Adds a CI smoke check that installs the built wheel into an isolated target, imports it outside the checkout, and checks all six resource files.
• Removes trailing whitespace from a docstring without changing runtime logic.

File	Description
pyproject.toml	Configures subpackage discovery and runtime resource inclusion.
moha/​hamiltonians.py	Removes trailing whitespace from the HamHeisenberg docstring.
.github/​workflows/​main.yml	Adds the installed-wheel import and resource smoke check.

It looks fine to me.

Not approved since test fails.

I traced the failed check to actions/setup-python being unable to find Python 3.10.12 on the Ubuntu 26.04 runner. I pinned the workflow to Ubuntu 24.04 in commit b6ce270. The new PR run is marked action_required and has no jobs, so it appears to need maintainer approval before it can run. Could someone approve the run? The package tests pass locally (9 passed).
