Programmatic purity / side-effect analysis API.

Determines whether code is pure (no side effects) or impure (I/O, mutations, random operations, etc.) by operating on the unified MetaAST representation.

Delegates to Metastatic.Analysis.Purity for the actual analysis, giving MetaCredo a stable API surface for downstream consumers.

Usage

alias Metastatic.Document
alias MetaCredo.Analysis.Purity

doc = Document.new(ast, :elixir)
{:ok, result} = Purity.analyze(doc)

result.pure?        # => true
result.effects      # => []
result.confidence   # => :high
