Supported Components Catalog

This page is the canonical user-facing inventory of YAML component types currently supported by PulsimCore v1.

• Catalog snapshot: 2026-03-07
• Canonical source in backend parser: component_node_arity() (core/src/v1/yaml_parser.cpp)
• Regression gate: python/tests/test_supported_components_catalog.py
