Functions

execute_create

Create nodes and edges from a pattern. Walks each pattern chain, creating nodes and edges as specified.

is_system_property

Check if a property name is a system-managed (read-only) property. Note: _valid_from and _valid_to are temporal but user-settable, so they are NOT system properties.

is_temporal_edge_property

Check if a property name is a temporal edge property (user-settable).

resolve_properties_mut

Resolve properties from a MapLiteral using mutable engine access. This is the preferred version that can register new property keys.

validate_no_system_properties

Validate that no system properties are being set by the user in a map literal.
