The human implementation checkpoint

At an implementation checkpoint, the Human Architect evaluates scope, acceptance criteria, architecture, tests, risks and evidence, then accepts, revises, rejects, reassigns or returns the work. The checkpoint turns a proposed result into a human decision; it does not automatically approve agent output.

Human Checkpoints apply throughout AI Architect Mastery's AI Driven Development Methodology. This page explains their acceptance role within IMPLEMENTATION and the Human Judgment exercised at these decision points.

What is Human Judgment?

Human Judgment is the human evaluation of evidence against intent, constraints, acceptance criteria, architectural direction and remaining risks to decide what happens next. Evidence provides observations; judgment determines whether those observations are relevant and sufficient for acceptance, correction or return.

It is part of Human Governance, not an extra Core phase or a tool feature. A Human Checkpoint is the decision point where that judgment becomes an explicit verdict. Passing tests do not transfer accountability to the agent.

What the human inspects

Compare the actual change with the approved TASK and underlying intent. Inspect the diff, the assertions and results of relevant tests, architectural fit, regression risks and explicitly unverified areas. An agent's summary helps locate evidence but does not replace reviewing it.

Five possible decisions

ACCEPT

The reviewed work satisfies its agreed scope and criteria with sufficient evidence for the decision.

REVISE

The approach remains suitable, but the result needs correction or additional evidence.

REJECT

The submitted result is not acceptable and should not progress as delivered.

REASSIGN

The work needs another responsibility holder, capability or execution environment.

RETURN

An earlier PRD, PLAN or TASK decision needs correction before implementation can continue.

Acceptance is not automatic release

Nothing merges without human review. A checkpoint is not a requirement to approve every microscopic action, and acceptance does not automatically authorize production deployment. Release remains part of the wider engineering process.
