SUBSYSTEM ARCHITECTURE & TELEMETRY BLUEPRINT
1. CLIENT TELEMETRY CAPTURE ENGINE
Real-time metrics are captured directly via browser
PerformanceObserver and PerformanceNavigationTiming APIs. Navigation timing isolates DNS lookups, TCP socket handshakes, TLS setup, and TTFB latency directly at wire level.
2. PROTOCOL & KERNEL TELEMETRY
System telemetry ingests eBPF kernel probes and Linux cgroup counters. Real-time CPU, RSS memory footprint, and network packet ingress rates are streamed over a local high-frequency
NATS JetStream pub/sub messaging channel.
3. EDGE PIPELINE BINDING
Inbound requests terminate at the ingress layer (
origin-web container), preserving ALPN protocol negotiation (HTTP/2 & HTTP/3 QUIC) and header telemetry prior to edge caching pipeline distribution.
