## AI interpretation — verify before relying

immutabledict provides an immutable, hashable wrapper around dictionaries that implements the complete mapping interface, allowing it to serve as a drop-in replacement for dicts where immutability is required.

Verdict: immutabledict is a lightweight, well-maintained MIT-licensed library with zero dependencies and no known vulnerabilities. It offers a pure-Python alternative to frozendict for applications needing immutable dictionary semantics across modern Python versions.
