why
The lineage behind the proposition with the given id, assembled from its durable fields.
Return
the lineage, or null if no such proposition exists; null by default
open fun whyExplain(propositionId: String, contextId: <Error class: unknown class>?): PropositionLineage?
The lineage behind propositionId, confined to contextId: a proposition in another context is treated as absent (null). A null context is unscoped — exactly the plain whyExplain overload. Routed here only when honorsContextFilter is true; the default body delegates to the unscoped overload.
Parameters
context
the context the proposition must belong to; null keeps it unscoped
