4Swapp Platform: System Overview (production) Diagram

User.API → User.Application (MediatR, user consumers) → Application → Domain
Admin.API (folder Swap.API) → Application (admin services, events, consumers) → Domain
Persistence owns ApplicationDBContext (one SQL context for both app layers) and 200+ migrations
Infra libs: Swapp.ElasticSearch, Swapp.ClickHouse, Swapp.Payment, Services (Blob, mail), 4Swapp.Common (NuGet)
Hangfire and Reporting.API reuse the same libraries; Reporting has its own ReportingDbContext

Kebab-case queues prefixed by RabbitMq:Envirnment; EF outbox on every host since Sept 2026
LisitngUpdated → ListingUpdatedEventHandler runs in both APIs and rebuilds the Elasticsearch document
ListingApproved / ListingRejected consumers run only in Admin.API; payment consumers only in User.API
Notifications are sent to {env}-notificationQueue via ReliablePublishService with a PendingMessages spool
Hangfire replays spooled messages every minute (Pending-Message-Reprocessing-Job)

SQL Server is the source of truth; public search/feed/details read Elasticsearch; owner and admin reads use SQL
View, call and WhatsApp counters land in ClickHouse via the Azure Function, then Hangfire copies them to SQL and ES
Redis caches home feed, lookups, add-on slot config and distributed locks for points
Admin.API also uses Redis and Blob (not drawn); OpenAI embeddings are produced by both APIs

Branch = environment: master → *.4sw.app, beta → *beta.4sw.app, development → *dev.4sw.app
Jenkins commits image.tag bumps; Argo CD applies every chart with prune + self-heal; kubelets pull from ACR
ConfigMaps hold appsettings with {{Name}} placeholders replaced from Key Vault secrets at startup
nginx ConfigMap (owned by user-api chart): Cloudflare real-IP, per-IP limits on /api/Listing/getall, OTP redaction
Logs: Vector → ClickHouse access logs, Promtail → Loki, fluent-bit → Elastic Cloud; Elastic APM disabled

Web portal (Angular SSR), Flutter app, both admin portals, CRM API/portal, store page, VFCloud SMS
Identity service (OpenIddict) and Notification service consume the same RabbitMQ and Redis
4Swapp.Common NuGet supplies AggregateRoot, ICacheService, IUserAuthService and shared event contracts
