What happens inside a single Voidly probe run: the measurement execution loop, DNS and TCP and TLS and HTTP data capture, result serialization and signing, and the upload path that delivers a signed ProbeResult to the ingest pipeline.

How Voidly probes maintain connectivity and upload measurements from networks that actively block VPN protocols — QUIC/443 transport, domain fronting via CDN SNI fronting, TLS certificate pinning against MITM, local SQLite buffering (500 MB cap, 48h window), and metered-connection backoff.

How Voidly probes preserve measurement data during upload failures — a 72-hour SQLite ring buffer with anomaly-safe eviction, LZ4 batch compression reducing median batch size from 47KB to 9KB, exponential backoff retry up to 4 hours, priority queue for anomalous measurements, chunked upload with per-chunk acknowledgment, and 0.003% measurement loss rate across 37 probes over 6 months.

How the Voidly desktop probe works: Tauri 2 cross-platform app, Cloudflare boringtun WireGuard, tun-rs TUN device, X25519-Dalek on-device key generation, and operator anonymity as a design constraint.

How the Voidly probe test runner orchestrates concurrent measurements inside the Tauri app: tokio Semaphore with 3 permits, MeasurementState machine (Pending → Running → Success/Error/Timeout), per-layer timeout budgets (DNS 3s, TCP 5s, TLS 8s, HTTP 15s, total 30s), Ed25519 measurement signing, mpsc upload queue with capacity 200, and why per-layer timeouts are themselves evidence of DNS-layer interference.

A step-by-step breakdown of how each Voidly probe test works: DNS resolution, TCP handshake, TLS negotiation with certificate chain validation, HTTP request execution, response body fingerprinting, control comparison, and how every layer maps to interference types in the anomaly classifier.
