Crate nexcore_drug 

nexcore-drug

Drug entity domain models — identity, classification, indications, safety signals, label status, and cross-drug analysis.

T1 Primitive Grounding

Concept	Primitive	Symbol	Role
Drug struct	State	ς	Central mutable domain aggregate
DrugClass / SignalVerdict / LineOfTherapy / ComparisonResult	Sum	Σ	Variant classification
DrugAnalysis trait methods	Mapping	μ	Transform aggregate → view
Option fields (rxcui, owner, approval_year, …)	Void	∅	Strategic absence
ContingencyTable cells (a, b, c, d)	Quantity	N	Disproportionality magnitudes
on_label / off_label filter	Comparison	κ	Predicate selection
Serialize / Deserialize	Persistence	π	Cross-boundary transport
::new() constructors	Existence	∃	Aggregate instantiation
Trait method chains	Causality	→	Query → result pipelines

Peer Architecture

Drug and Company are peer aggregates. nexcore-drug does NOT depend on nexcore-pharma. The owning manufacturer is stored as Option<String>. A strategy crate composes the two peers when cross-aggregate analysis is required.

Modules

• id: DrugId newtype (type-safe string identity)
• class: DrugClass enum (16 variants + Other)
• indication: Indication, LineOfTherapy
• signal: SignalEntry, ContingencyTable, SignalVerdict
• drug: Drug aggregate
• analysis: DrugAnalysis trait + DefaultDrugAnalysis implementation
