# Module Boundaries

> Architecture only. Module inventory → [module-registry.md](../module-registry.md)

## Core Platform

**Owns:** tenants, domains, plans, features, subscriptions, entitlement checks, service/module registry, internal service tokens, outbox/inbox (core), audit log, core users, tenant memberships (operational), onboarding, public tenant-site resolution.

**Must not own:** business journals, CRM entities, restaurant menus, file blobs, SMS campaigns.

**Must not own:** business rules, direct DB access, SQLAlchemy/Alembic, entitlement computation.

## Future Business Modules

Each module (Accounting, CRM, Restaurant, Ecommerce, …) owns its database and domain APIs. Cross-module coupling is API/event only. Financial postings go only through Accounting Posting Engine ([ADR-010](adr/ADR-010.md)).

### CRM (Sales CRM)

**Owns:** Lead, Contact, Organization (business account), Opportunity, Pipeline, PipelineStage, SalesActivity, Task, Meeting, CallLog, Sales Timeline, Comment/Mention, Bookmark, Sales Team, Playbook, Forecast, Goal, Target, Win/Loss, Quote (sales), CRM publish events.

### Loyalty (Enterprise Loyalty Platform)

**Owns:** LoyaltyProgram, MembershipTier, Member, PointAccount (shell; ledger in later phases), Reward catalog shell, Campaign shell, Loyalty audit, Loyalty publish events.

**Must not own:** CRM sales entities, Accounting postings, Notification delivery, Identity, Wallet UI (frontend), Restaurant/Marketplace/Ecommerce/Sports Center/Delivery/Experience domain data — those modules consume Loyalty via API/Events only.

### Communication (Enterprise Communication Platform)

**Owns:** Provider configs, sender numbers, message templates, manual contacts, dynamic contact-source configs, messages, queue/DLQ, delivery timeline, provider logs, OTP challenges, webhook receipts, communication audit; outbound provider adapters.

**Must not own:** CRM/Loyalty/Restaurant/Marketplace/Sports Center/Delivery/Experience business entities; must not be embedded inside those modules. Auth OTP path in Core remains separate until explicitly migrated.

### Sports Center Platform

**Owns:** Sports members, memberships/membership types, coaches, attendance/access devices, bookings, facilities/courts/equipment, programs/workouts, competitions/sports events, locker/medical/nutrition shells as scoped, sports reports/analytics shells, sports_center publish events, integrations adapters (client-side only).

**Must not own:** Accounting journals/Posting Engine, Sales CRM aggregates, Loyalty ledger/campaigns, Communication providers, Core tenant membership, Restaurant/Ecommerce domains, Delivery logistics domain, Experience page/site/theme ownership, product AI platform, Automation engine.

### Hospitality Platform

**Owns:** Venues (cafe/restaurant/bakery/… formats), branches, dining areas/tables, menus/categories/items shells, hospitality roles/permissions, bundle definitions, tenant bundle activation, feature toggles, hospitality configurations/settings/events/audit, hospitality publish events, connector contracts (client-side only).

**Must not own:** Accounting journals/Posting Engine, Sales CRM aggregates, Loyalty ledger/campaigns, Communication providers, Core tenant membership, Delivery logistics domain, Experience page/site/theme ownership (menus-as-pages are Experience; menu/item catalog source of truth is Hospitality), product AI platform, Automation engine, POS/kitchen/ordering engines until their phases.

## Shared Library (`backend/shared-lib`)

**Owns:** JWT validation helpers, phone normalization, event envelope types, shared exceptions/responses.

**Must not own:** tenant business workflows or service-specific repositories.

## Boundary Rules

1. No cross-database foreign keys.
2. No importing another service's models.
3. Feature gates use Core entitlement API.
4. Frontend talks to public/versioned APIs only.
5. Providers are integrated behind module/provider adapters — see [integration-architecture.md](integration-architecture.md).

# Service Architecture

## Internal Layering (every backend service)

```
API (routers)  →  Services (business logic)  →  Repositories  →  Models (DB)
                         ↑
                     Schemas (Pydantic DTOs)
```

| Layer | Allowed | Forbidden |
| --- | --- | --- |
| API / Views | Auth deps, validation, HTTP mapping | Business rules, raw SQL |
| Services | Domain logic, orchestration, events | HTTP concerns, UI |
| Repositories | Queries/persistence | Business decisions |
| Models | Schema mapping | Business workflows |

## Core Package Layout

- `core/` — config, database, cache, security, logging
- `middlewares/` — tenant resolution
- `workers/` — Celery tasks (outbox, SSL provision, …)
- `api/v1/` — versioned routers
- `tests/` — automated tests

## Adding a Service

1. New folder under `backend/services/<name>/`
2. Independent database + Alembic
3. Register in Core service/module registry
4. Document in [module-registry.md](../module-registry.md)
5. UI only in `frontend/`, API-only access
6. Follow [coding-standards.md](../development/coding-standards.md)

# Database Architecture

> Architecture only. Column-level reference → [database-schema.md](../reference/database-schema.md)

## Pattern

**Database-per-service** ([ADR-001](adr/ADR-001.md)).

| Service | Database |
| --- | --- |
| Core Platform | `core_platform_db` |
| Identity & Access | `identity_access_db` |
| Accounting (future) | `accounting_db` |
| CRM | `crm_db` |
| Loyalty | `loyalty_db` |
| Communication | `communication_db` |
| Sports Center | `sports_center_db` |
| Delivery (planned) | `delivery_db` |
| Experience Platform (registered) | `experience_db` |
| Hospitality | `hospitality_db` |
| Ecommerce (future) | `ecommerce_db` |
| Website Builder (historical scaffold; prefer `experience_db`) | `website_builder_db` |
| Live Chat (future) | `live_chat_db` |
| AI Assistant (future) | `ai_assistant_db` |
| Smart Messenger (future) | `smart_messenger_db` |
| SMS Panel (future) | `sms_panel_db` |
| Link Shortener (future) | `link_shortener_db` |
| Notification (future) | `notification_db` |
| File Storage (future) | `file_storage_db` |

## Hard Rules

1. No direct queries across service databases.
2. No cross-DB foreign keys.
3. Every business table includes `tenant_id` ([ADR-003](adr/ADR-003.md)).
4. IDs are UUID; timestamps are timezone-aware.
5. Migrations via Alembic per service; never edit applied migrations in production.
6. Conceptual schemas for future services are documented in reference docs until migrations exist.

## Core Platform Ownership

Tenants, domains, plans/features/subscriptions, registries, internal tokens, outbox/inbox, audit logs, core users, operational `tenant_memberships`.

## Identity Ownership

`user_profiles`, identity-layer `tenant_memberships` (not the Core table — [ADR-007](adr/ADR-007.md)).

## Dual Membership Clarification

| Database | Table | Role |
| --- | --- | --- |
| `core_platform_db` | `tenant_memberships` | Workspace authorization source of truth |
| `identity_access_db` | `tenant_memberships` | SSO membership listing |

====================
# Event-Driven Architecture

## Envelope

All events use `shared.events.EventEnvelope`:

```json
{
  "event_id": "uuid",
  "event_type": "tenant.created",
  "aggregate_type": "tenant",
  "aggregate_id": "uuid",
  "tenant_id": "uuid|null",
  "source_service": "core-service",
  "payload": {},
  "occurred_at": "ISO-8601"
}
```

## Outbox → Inbox ([ADR-006](adr/ADR-006.md))

1. Producer writes business row + `outbox_events` in one transaction.
2. Worker (`process_outbox_events`) publishes pending rows.
3. Consumer inserts `inbox_events` keyed by `event_id` (idempotency) then handles payload.

## Naming

`{aggregate}.{past_tense_verb}` — e.g. `tenant.created`, `subscription.updated`, `user.registered`.

## Catalog

Canonical list → [event-catalog.md](../reference/event-catalog.md)

## Future

Replace in-process/Celery-only publish with a real message bus without changing envelope or outbox ownership.
