• Mustermann AST patterns compile into RFC 6570 URI template strings via to_templates, converting named captures to standard expressions, splats to reserved-character expansions, and optional segments into distinct permutation templates.
• Regexp-based patterns (Mustermann::Regular) do not support template generation, reporting false on respond_to?(:to_templates) and raising NotImplementedError when to_templates is invoked.
• Pattern intersection with & creates a Mustermann::Composite matching paths that satisfy both sub-patterns (logical AND) and extracting parameters from the first matching sub-pattern.
• Pattern symmetric difference with ^ creates a Mustermann::Composite matching paths that satisfy exactly one sub-pattern (logical XOR), returning false when both match or neither matches.
• Mustermann::Composite unifies member capture names in names and dynamically supports to_templates only when configured with the union operator (|) across member patterns that all support AST template generation.
• Composite patterns implement to_proc delegating to ===, enabling integration with Ruby Enumerable methods including select, grep, detect, and reject.
