The Meridian Model · Four Publications

AI-assisted work keeps failing in recognizable patterns.

The Meridian Model is a body of work comprising Human-Assisted AI, The Confluent Method, The Halocline, and The Discipline of Dependable Software. Together they name the failure patterns of AI-assisted work, define the method that responds to them, mark the boundary where that method stops, and anchor the whole system in the engineering philosophy underneath.

The publications

Four works. One system.

Human-Assisted AI is the gateway. The Confluent Method is the practical path. The Halocline is the boundary branch. The Discipline of Dependable Software is the foundation underneath the whole model.

The Halocline is a branch from the method boundary — important, but not the gateway.

The Failure Mode Catalog.

The Failure Mode Catalog: eight named patterns of AI-assisted work failure — Silent Divergence, Compressed Context Corruption, The Spiral, The Tool Trap, Collateral Mutation, Confidence Poisoning, The Phantom Agreement, and Test Laundering. Each card gives a short description and a first-response recommendation.

Eight patterns most readers have already lived through.

Silent Divergence. Compressed Context Corruption. The Spiral. The Tool Trap. Collateral Mutation. Confidence Poisoning. The Phantom Agreement. Test Laundering.

Once the patterns have names, teams stop treating them as isolated surprises. That is why Human-Assisted AI works as the gateway into the rest of the model — recognition is what pulls a practitioner into the method.

How the works relate

One system. Two ways to read it.

Most readers enter through recognition. Readers who want the philosophy first can work from the foundation upward. Both paths lead to the same place.

Foundation

The Discipline of Dependable Software. The engineering philosophy beneath every other work — understandable, traceable, controllable systems.

Recognition layer

Human-Assisted AI. The failure surfaces, the human role, and the reason discipline matters before any method is applied.

Practice layer

The Confluent Method. The actionable method for Creative AI Domain work. Small steps, verified output, human-confirmed completion.

Boundary branch

The Halocline. The consequence of discovering that the method stops at the agentic / OAID boundary — and what to do with that.

Published & citable
