Axiomatization Decision LogRegistro de Decisões
1 Identity-Giving FunctionFunção Identitária
Function class
GravityCollectionFunction ⊑ ContainmentFunction
Realized in
GravityCollectionProcess ⊑ MaterialContainment
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.
2 Genus DeterminationDeterminação do Gênero
Vesselbfo:Object (BFO_0000030)
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).
3 Differentia SpecificaDiferença Específica
∃bearerOf.GravityCollectionFunction

Bears a gravity collection function: collects and holds the heavier of two or more fluid phases, accumulated by gravity, rather than serving general process storage or pressure containment.

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).
4 Necessary PartsPartes Necessárias

No necessary parts recorded.

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.

OutputsSaídas

TransformationTransformação
the heavier fluid phase settles and accumulates in the reservoir under gravity, held until removed
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).

How much independent secondary research backs this term — not how correct it is. "Full" means a non-primary source was quoted directly and covered several distinct aspects of the concept, not just its function. "Partial" means secondary research happened but covered less. "None" means only the primary definition was used. A "full" term can still contain an error, and a "none" term can still be entirely correct — this tracks whether the research step ran, not the result.Quanto de pesquisa secundária independente sustenta este termo — não o quão correto ele é. "Full" significa que uma fonte não-primária foi citada literalmente e cobriu vários aspectos distintos do conceito, não apenas sua função. "Partial" significa que houve pesquisa secundária, mas com cobertura menor. "None" significa que só a definição primária foi usada. Um termo "full" ainda pode conter um erro, e um termo "none" ainda pode estar totalmente correto — isso rastreia se a etapa de pesquisa ocorreu, não o resultado.
