"""FablePool govtool test suite.

This package contains the pytest suite for the amendment pipeline:

- unit tests for canonicalisation, keys, ledger, eligibility, ballots,
  tally, classifier, and fork tooling;
- end-to-end tests that drive one amendment through the vote gate to
  ratification and block two others (threshold failure, quorum failure);
- smoke tests for the CLI entry point and the shipped demo script;
- structural validation of the shipped constitution source tree.

All cross-module calls go through ``tests/helpers.py`` (the adapter
layer) so the suite asserts *behaviour* rather than exact parameter
spellings. If a govtool function is renamed, fix the alias tables in
``helpers.py`` once instead of editing every test.
