Henry Help: (Dunham Computer Services) Proof Before Swap is new hackathon work for Henry Help, an existing private small-business tech-support product. We built an isolated Node.js evaluation lab to make a proposed AI model change inspectable before any production decision. It freezes seven synthetic support scenarios, a public surrogate prompt, rubric and settings; runs the same cases through separate Meta Muse Spark 1.3 and OpenAI GPT-6.1 Terra Responses API adapters; records the model that actually answered; preserves failed and missing cases in the denominator; and binds named human reviews to exact outputs. Live calls completed 7/7 cases for each model. One reviewer scored all 14 answers, with no safety, escalation or honesty gate failures. The one-sample case scores were 66/70 for Muse and 70/70 for Terra, which do not establish a general model ranking. The lab has no device actions, customer data, or production model-switch control. The actual production baseline remains uncaptured.

It's live with paying customers and a patent pending. I'm not just building projects, I'm building my independence one lane at a time.
