Identity-Giving Function
✓ done
⚠ not anchored
ElectricalSwitchingFunction → ElectricalSwitchingProcess
▼
COPI-Core operation
⚠ Process parent
PlannedProcess reaches no COPI-Core operation, and no gap (out of scope / coverage gap) is recorded.
LLM rationale:
CFIHOS and ISO 15926 give the same functional definition — 'turns electrical current on and/or off' — with no structural constraint, so the function is identity-giving and sufficient.

Genus Proximus
✓ done
MaterialArtifact
▼
Genus (genus proximum)
Most specific superclass — may be a domain class like "Valve" or an IOF-Core root.
BFO/IOF-Core Root
bfo:Object branch
bfo:ObjectAggregate branch
bfo:ImmaterialEntity branch
LLM rationale:
ISO 15926 types it as an ARTEFACT and a SWITCHING DEVICE; MaterialArtifact is the corresponding IOF root.

Differentia Specifica

Conditions that distinguish
Electrical Switch
from sibling classes under genus
MaterialArtifact.
Only what is not already entailed by the genus.
Differentia expression
Differentia (natural language)
LLM rationale:
Purely functional basis, stated identically by two independent standards, so equivalence is safe.

Necessary Parts
✓ done
no necessary parts
▼
Consider part-whole relations beyond subsumption:
hasComponentPartAtAllTimes (universal, structurally essential)
· hasComponentPartAtSomeTime (contingent, optional component)
LLM rationale:
No sub-component is named in any source definition for this term. validate_necessary_parts_quotes() requires a verbatim source_quote for every part, and there is nothing to quote — so no parts are asserted (ODR-022 §10.2).

Process Participation Signature ⟨I, O, T⟩
✓ done
ControlSignal → InformationContentEntity
▼
Inputs (I)
Outputs (O)
Transformation (T)
LLM rationale:
Energy is not a participant (ODR-010 §5.1): the switch's electrical demand is a quality (bearer_of ElectricalCurrent), while the process participants are the command and the resulting state.
