#### Events (events.go)

## Build Verification ✓

```bash
$ go fmt ./...
# No output - all formatted

$ go vet ./...
# No issues

$ go build ./...
# Successful

$ go test ./...
ok      github.com/Trusera/ai-bom/trusera-sdk-go       0.559s

$ go test -cover ./...
ok      github.com/Trusera/ai-bom/trusera-sdk-go       0.559s  coverage: 85.4% of statements
```

## Dependency Check ✓

```bash
$ go mod graph
# No dependencies (stdlib only)
```

## Thread Safety ✓
- [x] Mutex protection on event queue
- [x] Concurrent request handling tested
