## Context

Gyms, clubs, and sports facilities need members, memberships, coaches, attendance/access, booking, training programs, competitions, and related operations. Embedding this inside CRM, Loyalty, Accounting, or Restaurant would couple unrelated domains and block reuse.

TorbatYar already has independent platform services for Loyalty ([ADR-011](ADR-011.md)) and Communication ([ADR-012](ADR-012.md)). Sports operations need the same independence with a dedicated database and permission tree.

## Decision

1. Introduce `sports_center` as an **independent business platform service** with sole ownership of `sports_center_db` ([ADR-001](ADR-001.md)).
2. Permission prefix: `sports_center.*`. Publish-only domain events: `sports_center.*`.
3. Row-level multi-tenancy via `tenant_id` ([ADR-003](ADR-003.md)).
4. Consume Accounting, CRM, Loyalty, and Communication **only** via REST API and Events — never shared tables or foreign model imports.
5. Financial journals only through Accounting Posting Engine ([ADR-010](ADR-010.md)).
6. Messaging only through Communication ([ADR-012](ADR-012.md)).
7. Loyalty points/rewards only through Loyalty ([ADR-011](ADR-011.md)).
8. Implementation phases are registered as **Phase 9.0–9.10** in [phase-manifest.yaml](../../ai-framework/phase-manifest.yaml); roadmap in [sports-center-roadmap.md](../../sports-center-roadmap.md).
9. Product AI and Automation remain optional and external ([ai-architecture.md](../ai-architecture.md)).

## Consequences

### Positive

- Clear ownership for sports operations
- Reusable integrations with platform services
- Enforceable tenancy, audit, and boundary tests

### Negative

- Additional deployable service and database
- Eventual consistency for cross-service customer views

### Neutral

- Scaffold may exist under `backend/services/sports_center` before Phase 9.0 implementation; registration precedes business code

## Alternatives Considered

1. Sports subsystem inside CRM — rejected (CRM is Sales-only).
2. Sports tables inside Core — rejected (violates business-module boundaries and ADR-001).
3. Per-tenant bespoke apps without a service — rejected (not SuperApp-native).
