+Enums in Clean Architecture (Strict & Final)
+
+This document defines how enums are modeled, placed, and used in a strict Clean Architecture setup.
+
+Enums are one of the most common sources of architectural leakage. This guide removes all ambiguity.
+
+⸻
+
+1. Core Principle
+
+Enums represent knowledge.
+Knowledge must live where it is true.
+
+Therefore:
+	•	Not every enum is a domain enum
+	•	Enums must never cross architectural boundaries blindly
+	•	Ports must remain neutral
+
+⸻
+
+2. Enum Categories (Authoritative)
+
+There are four and only four valid enum categories:
+	1.	Domain Enums
+	2.	Application (Workflow) Enums
+	3.	Transport Enums (API)
+	4.	UI Enums (Frontend)
+
+Each category has strict placement and usage rules.
+
+⸻
+
+3. Domain Enums
+
+Definition
+
+A Domain Enum represents a business concept that:
+	•	has meaning in the domain
+	•	affects rules or invariants
+	•	is part of the ubiquitous language
+
+Examples:
+	•	LeagueVisibility
+	•	MembershipRole
+	•	RaceStatus
+	•	SponsorshipTier
+	•	PenaltyType
+
+⸻
+
+Placement
+
+core/<context>/domain/
+├── value-objects/
+│   └── LeagueVisibility.ts
+└── entities/
+
+Preferred: model domain enums as Value Objects instead of enum keywords.
+
+⸻
+
+Example (Value Object)
+
+export class LeagueVisibility {
+  private constructor(private readonly value: 'public' | 'private') {}
+
+  static from(value: string): LeagueVisibility {
+    if (value !== 'public' && value !== 'private') {
+      throw new DomainError('Invalid LeagueVisibility');
+    }
+    return new LeagueVisibility(value);
+  }
+
+  isPublic(): boolean {
+    return this.value === 'public';
+  }
+}
+
+
+⸻
+
+Usage Rules
+
+Allowed:
+	•	Domain
+	•	Use Cases
+
+Forbidden:
+	•	Ports
+	•	Adapters
+	•	API DTOs
+	•	Frontend
+
+Domain enums must never cross a Port boundary.
+
+⸻
+
+4. Application Enums (Workflow Enums)
+
+Definition
+
+Application Enums represent internal workflow or state coordination.
+
+They are not business truth and must not leak.
+
+Examples:
+	•	LeagueSetupStep
+	•	ImportPhase
+	•	ProcessingState
+
+⸻
+
+Placement
+
+core/<context>/application/internal/
+└── LeagueSetupStep.ts
+
+
+⸻
+
+Example
+
+export enum LeagueSetupStep {
+  CreateLeague,
+  CreateSeason,
+  AssignOwner,
+  Notify
+}
+
+
+⸻
+
+Usage Rules
+
+Allowed:
+	•	Application Services
+	•	Use Cases
+
+Forbidden:
+	•	Domain
+	•	Ports
+	•	Adapters
+	•	Frontend
+
+These enums must remain strictly internal.
+
+⸻
+
+5. Transport Enums (API DTOs)
+
+Definition
+
+Transport Enums describe allowed values in HTTP contracts.
+They exist purely to constrain transport data, not to encode business rules.
+
+Naming rule:
+
+Transport enums MUST end with Enum.
+
+This makes enums immediately recognizable in code reviews and prevents silent leakage.
+
+Examples:
+	•	LeagueVisibilityEnum
+	•	SponsorshipStatusEnum
+	•	PenaltyTypeEnum
+
+⸻
+
+Placement
+
+apps/api/<feature>/dto/
+└── LeagueVisibilityEnum.ts
+
+Website mirrors the same naming:
+
+apps/website/lib/dtos/
+└── LeagueVisibilityEnum.ts
+
+
+⸻
+
+Example
+
+export enum LeagueVisibilityEnum {
+  Public = 'public',
+  Private = 'private'
+}
+
+
+⸻
+
+Usage Rules
+
+Allowed:
+	•	API Controllers
+	•	API Presenters
+	•	Website API DTOs
+
+Forbidden:
+	•	Core Domain
+	•	Use Cases
+
+Transport enums are copies, never reexports of domain enums.
+
+⸻
+
+Placement
+
+apps/api/<feature>/dto/
+└── LeagueVisibilityDto.ts
+
+or inline as union types in DTOs.
+
+⸻
+
+Example
+
+export type LeagueVisibilityDto = 'public' | 'private';
+
+
+⸻
+
+Usage Rules
+
+Allowed:
+	•	API Controllers
+	•	API Presenters
+	•	Website API DTOs
+
+Forbidden:
+	•	Core Domain
+	•	Use Cases
+
+Transport enums are copies, never reexports of domain enums.
+
+⸻
+
+6. UI Enums (Frontend)
+
+Definition
+
+UI Enums describe presentation or interaction state.
+
+They have no business meaning.
+
+Examples:
+	•	WizardStep
+	•	SortOrder
+	•	ViewMode
+	•	TabKey
+
+⸻
+
+Placement
+
+apps/website/lib/ui/
+└── LeagueWizardStep.ts
+
+
+⸻
+
+Example
+
+export enum LeagueWizardStep {
+  Basics,
+  Structure,
+  Scoring,
+  Review
+}
+
+
+⸻
+
+Usage Rules
+
+Allowed:
+	•	Frontend only
+
+Forbidden:
+	•	Core
+	•	API
+
+⸻
+
+7. Absolute Prohibitions
+
+❌ Enums in Ports
+
+// ❌ forbidden
+export interface CreateLeagueInputPort {
+  visibility: LeagueVisibility;
+}
+
+✅ Correct
+
+export interface CreateLeagueInputPort {
+  visibility: 'public' | 'private';
+}
+
+Mapping happens inside the Use Case:
+
+const visibility = LeagueVisibility.from(input.visibility);
+
+
+⸻
+
+8. Decision Checklist
+
+Ask these questions:
+	1.	Does changing this enum change business rules?
+	•	Yes → Domain Enum
+	•	No → continue
+	2.	Is it only needed for internal workflow coordination?
+	•	Yes → Application Enum
+	•	No → continue
+	3.	Is it part of an HTTP contract?
+	•	Yes → Transport Enum
+	•	No → continue
+	4.	Is it purely for UI state?
+	•	Yes → UI Enum
+
+⸻
+
+9. Summary Table
+
+Enum Type	Location	May Cross Ports	Scope
+Domain Enum	core/domain	❌ No	Business rules
+Application Enum	core/application	❌ No	Workflow only
+Transport Enum	apps/api + website	❌ No	HTTP contracts
+UI Enum	apps/website	❌ No	Presentation only
+
+
+⸻
+
+10. Final Rule (Non-Negotiable)
+
+If an enum crosses a boundary, it is in the wrong place.
+
+This rule alone prevents most long-term architectural decay.
