edge_registry.py¶

Overview¶

This file contains 4 documented elements.

Functions¶

_load_visual_rules()¶

Load em_visual_rules.json once. Returns None on failure.

_load_connections_datamodel()¶

Load s3Dgraphy_connections_datamodel.json once.

resolve_edge_style(edge_type)¶

Return the style dict for edge_type, or None if not known.

Lookup order: 1. _PYARCHINIT_EDGE_OVERRIDES (override-wins) 2. em_visual_rules.json edge_style.{edge_type}.style 3. None (caller uses default)

Returned dict shape: {"color": "#RRGGBB", "line_style": "solid"|"dashed"|"dotted", "width": int}

Parameters: - edge_type

is_paradata_edge(edge_type)¶

True iff edge_type is a paradata-flow edge (rendered dashed in the AI03 post-processor; excluded from rapporti round-trip in AI04).

Uses the connections datamodel when available — paradata edges have allowed_connections.source or .target containing PropertyNode / DocumentNode / ExtractorNode / CombinerNode. Falls back to the hardcoded _HARDCODED_PARADATA_EDGES set when the datamodel is unavailable.

Structural edges listed in _STRUCTURAL_NON_PARADATA_EDGES are always reported as non-paradata, even if their connections-datamodel allowed_connections includes paradata-class endpoints (e.g. is_in_location allows PropertyNode sources for "this property measurement was taken at this place").

Parameters: - edge_type
