Connection classifier type matching

[avrabe]

Context

Connection validation currently checks direction (in/out) but not data type compatibility. A connection from out data port SensorData to in data port ControllerInput should verify that SensorData and ControllerInput are type-compatible.

Requirements

• Resolve classifier references on connection endpoints
• Check type compatibility: exact match, subtype (extends), or compatible base type
• Validate access connection types (provides/requires classifiers must match)
• Feature group connection type compatibility

References

• AS5506 §9.3 (port connection legality), §9.5 (access connections)
• OSATE2: PortConnectionConsistency.java

Acceptance criteria

• Connection validation checks data classifier compatibility
• Incompatible classifiers produce diagnostics
• Subtype relationships (extends) are considered compatible
• Tests for matching, mismatched, and subtype connections
