# Scanner Platform Events (Redis Streams)

## Module
Platform

## Status
IMPLEMENTED

## Description
Scanner WebService emits `scanner.report.ready` and `scanner.scan.completed` platform events via Redis Streams with DSSE envelopes embedded verbatim, configurable via `scanner:events:*` settings.

## Implementation Details
- **AnalyticsIngestionService**: `src/Platform/StellaOps.Platform.Analytics/Services/AnalyticsIngestionService.cs` -- subscribes to event stream (configurable via `scanner:events:*` settings); filters for `scanner.report.ready` and `scanner.scan.completed` event kinds from OrchestratorEventEnvelope; tenant-scoped event filtering
- **ScannerOrchestratorEvents**: `src/Platform/StellaOps.Platform.Analytics/Models/ScannerOrchestratorEvents.cs` -- event models for scanner platform events
- **RekorEvents**: `src/Platform/StellaOps.Platform.Analytics/Models/RekorEvents.cs` -- Rekor transparency log event models
- **AdvisoryEvents**: `src/Platform/StellaOps.Platform.Analytics/Models/AdvisoryEvents.cs` -- advisory event models
- **IEventStream/IEventStreamFactory**: from `StellaOps.Messaging` -- event stream abstraction for subscribing to platform events with position tracking (Beginning/End)

## E2E Test Plan
- [ ] Verify scanner.report.ready events are consumed and processed by analytics ingestion
- [ ] Test scanner.scan.completed events trigger appropriate analytics updates
- [ ] Verify DSSE envelopes are embedded verbatim in event payloads
- [ ] Test event stream position tracking resumes from correct position after restart
- [ ] Verify tenant filtering skips events from non-allowed tenants
