> OBJECTIVE: Neutralize the 220lb Opponent.
On January 8, 2024, I initiated a new project: Brazilian Jiu-Jitsu. I had delayed this integration for years, calculating the risk of injury to be too high for a 57-year-old frame. My risk assessment was correct.
Status Report: On Day 01, a 220lb Blue Belt applied dynamic pressure (Knee-on-Belly) to my chassis. The result was a fractured right rib. I did not quit. I continued to attend everyday with compromised hardware.
I realized the standard BJJ operating system fails when the weight variance exceeds 50lbs. To patch this vulnerability, I re-activated 25 years of Hapkido Joint Mechanics. I stopped fighting their strength (Resistance) and started dismantling their hinges (Architecture).
The Wrist Lock Lab is the documentation of that system. It is not about being tough. It is about being structurally sound.
In engineering, a system is only as reliable as its source data. I do not display these documents for status or vanity; I display them to establish Technical Integrity. My operating system is built on a foundation verified in 2006 (Advanced Locking Mechanics) and hardened in 2008 (Hapkido Black Belt). These are not trophies; they are the technical specifications of the operator.
