1. HTTP Request Arrives └─ Extract tracing context from headers └─ Create root span: "webhook_processing"
2. Circuit Breaker Check └─ State: CLOSED (allow request) └─ Record metrics: circuit_breaker_state=0
3. Execute Webhook Handler (with tracing) ├─ Child span: "signature_verification" │ └─ Duration: 0.5ms │ ├─ Child span: "payload_parsing" │ └─ Duration: 1.2ms │ └─ Record: request_size_bytes=1024 │ ├─ Child span: "edge_function_invoke" │ ├─ Circuit breaker wraps this call │ ├─ WASM metrics recorded │ └─ Duration: 8.3ms │ └─ Child span: "response_format" └─ Duration: 0.3ms └─ Record: response_size_bytes=512
4. On Success ├─ Circuit breaker: record_success() ├─ Metrics: webhook_requests_total{status="success"}++ ├─ Metrics: webhook_duration_seconds.observe(10.3ms) └─ Tracing: close all spans, export trace
5. On Failure ├─ Circuit breaker: record_failure() │ └─ Check if threshold exceeded → OPEN state ├─ Metrics: webhook_requests_total{status="failure"}++ └─ Tracing: mark span as error, export trace
