Keep the seams visible. MCP need not know the VM. Cancel need not know tool names. Wrong audit stands in for the real one. Compose without collapsing. Narration uses Eric's authorized AI voice clone. #EricFieldNotes
Full written post / accessibility read
A clean stack keeps the seams visible. A product starts, continues, and cancels through a UHP shaped or responses compatible job API. The harness calls tools through MCP or native tools it owns. The harness runs inside a chosen substrate with network, secrets, and file policy set before start.
MCP does not need to know which substrate holds the process. The product does not need to know MCP tool names to cancel a job and collect artifacts. The substrate does not need to speak UHP to enforce a kernel boundary.
When seams blur, reviews blur. A tools audit stands in for a job lifecycle review. A container flag checklist stands in for a kernel isolation decision. Name the seam you are actually testing.
Composition means the rows talk at defined interfaces. It does not mean one protocol box. My rule stays: name the layer before you merge the stack.

Four-beat scene transcript
1. Keep the seams visible.
A clean stack keeps the seams visible. A product starts, continues, and cancels through a UHP shaped or responses compatible job API. The harness calls tools through MCP or native tools it owns. The harness runs inside a chosen substrate with network, secrets, and file policy set before start.
Visual: Product job, tool calls, substrate policy.
2. Ignorance across seams is a feature.
MCP does not need to know which substrate holds the process. The product does not need to know MCP tool names to cancel a job and collect artifacts. The substrate does not need to speak UHP to enforce a kernel boundary.
Visual: MCP need not know the VM. Cancel need not know tool names.
3. Blurred seams blur reviews.
When seams blur, reviews blur. A tools audit stands in for a job lifecycle review. A container flag checklist stands in for a kernel isolation decision. Name the seam you are actually testing.
Visual: Wrong audit stands in for the real one.
4. Compose without collapsing.
Composition means the rows talk at defined interfaces. It does not mean one protocol box. My rule stays: name the layer before you merge the stack.
Visual: Three contracts, one working system.
