- Chains and Multihop: What They Give You and What They Cost - A second hop solves specific problems and creates new ones. What a chain actually buys, why a fallback path is not failover, and the trace multihop leaves in traffic.
- Measuring Blocking Correctly - A probe must measure the quantity by which the network actually breaks. Four requirements: volume, seriality, failure classification and vantage point.
- Three Axes of Traffic Shape: Why Two Mechanisms Demand Opposite Settings - One restriction demands splitting connections, another demands merging them. The contradiction dissolves once count, concurrency and volume become independent axes.
- Your VPN Check Says Timeout but the Connection Works — and Vice Versa - The built-in connection check in VPN clients measures the wrong quantity. That produces two symptoms: red-but-working, and the more dangerous green-but-broken.

- Xray-core Guide: Proxy Access, VLESS, REALITY, and XTLS - A practical Xray-core guide covering VLESS, REALITY, XTLS, proxy access patterns, client setup, and common network troubleshooting.
