Axiom type
LLM classification basis: function-based → ≡
Both cross-source definitions are purpose-based ('intended to collect the heavier phase... by making use of gravity'), naming no specific construction -- any reservoir meeting this gravity-collection purpose qualifies, matching the pattern of other purpose-defined Vessel subtypes.

Identity-Giving Function
✓ done
GravityCollectionFunction → GravityCollectionProcess ⊑ MaterialContainment
▼
COPI-Core operation
MaterialContainment via process parent MaterialContainment
LLM rationale:
Vessel's own function (ContainmentFunction) is too generic to distinguish a sump from any other container; GravityCollectionFunction narrows it to the specific gravity-driven collection purpose stated verbatim in both cross-source definitions -- matching the colleague's 'Drainage Collector' framing closely.

Genus Proximus

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:
Parent candidate RESERVOIR is not itself enriched; Vessel (already enriched, function=ContainmentFunction, exported) is the closest enriched supertype and matches the physical form (a container that holds an accumulated phase).

Conditions that distinguish
Sump
from sibling classes under genus
Vessel.
Only what is not already entailed by the genus.
Differentia expression
Differentia (natural language)
LLM rationale:
Functional type: the identity-giving function alone is necessary and sufficient, following the same minimal pattern as other purpose-defined Vessel subtypes (e.g. pig launcher, accumulator).

Necessary Parts
✓ done
no necessary parts
▼
Consider part-whole relations beyond subsumption:
hasComponentPartAtAllTimes (universal, structurally essential)
· hasComponentPartAtSomeTime (contingent, optional component)
LLM rationale:
No specific structural component is named in either cross-source definition; the only related terms.db entries found (SUMP MOUNTED CASING, SUMP PUMP, sump packer) describe equipment that mounts in or works with a sump, not components of the sump vessel itself.

Process Participation Signature ⟨I, O, T⟩
✓ done
PortionOfFluid → PortionOfFluid
▼
Inputs (I)
Outputs (O)
Transformation (T)
LLM rationale:
Passive gravity-driven accumulation signature, matching the genus Vessel; no active mechanical separation mechanism is asserted (distinguishing it from Separator-genus devices, which bear a distinct SeparationFunction).
