 `contracts-rb` adds small, explicit behavioral contracts to Ruby without imposing a type system. It supports parameter and return constraints, preconditions, postconditions, object invariants, state snapshots, mutation policies, exception declarations, introspection, and a dependency-free CLI.

 ## Why contracts-rb?
 
 Ruby tests describe expected examples; contracts keep critical method promises executable at runtime. Use them for domain boundaries, money movement, state transitions, service objects, and public library APIs. They are not a replacement for ordinary tests, schema validation, or authorization.

+0.4.0 wraps declared instance methods at definition time. The explicit singleton API (`contract_singleton` / `extend Contracts`) remains experimental. Static implication proofs for inheritance and deeper Rails instrumentation are intentionally deferred. Deep snapshots (`observe …, deep: true`) are supported for arrays, hashes, and sets.

+Maintainers validate with `bundle exec rubocop .`, `bundle exec rspec`, and `bundle exec rake build`. Pushing a `v*` tag runs [`.github/workflows/release.yml`](.github/workflows/release.yml), which publishes via [RubyGems Trusted Publishing](https://guides.rubygems.org/trusted-publishing/) (OIDC) and attaches `contracts-rb-<version>.gem` to the GitHub release.
