Status: COMPLETE ✅

Resolved by commit 3eac9c6.

Deliverables

File	Lines	Description
src/ogc-api/csapi/formats/sensorml/types.ts	852	Full SensorML 3.0 type hierarchy
src/ogc-api/csapi/formats/sensorml/types.spec.ts	462	23 type compilation & discriminator tests

Coverage

• 50 exported types covering the complete SensorML 3.0 process model
• Inheritance chain: DescribedObject → AbstractProcess → AbstractPhysicalProcess → concrete
• 4 concrete process types with string-literal type discriminators:
  • SimpleProcess, AggregateProcess, PhysicalComponent, PhysicalSystem
• SensorMLProcess discriminated union for type-safe narrowing via switch(proc.type)
• 20+ supporting types: Term, Document, Event, ResponsibleParty, CapabilityList, CharacteristicList, Settings, Position, ComponentList, ConnectionList, etc.
• SWE Common integration via import type { ... } from '../swecommon/types.js'

Verification

• tsc --noEmit: clean (zero errors)
• 23/23 SensorML tests pass
• 27/27 SWE Common tests pass (no regressions)
• All 400 CSAPI tests unaffected"
