Definition
What are human approval gates?
The human gates are the three points in the S1 Method where a named person must sign: H1 at Model, H2 at Decide and H3 at Deploy. AI can research, model and draft between the gates, but it cannot pass one. Each signature is kept as an approval record, and work moves on only once it exists.
Also called: human gates, H1, H2 and H3, signed human gates.
Explained in full on The S1 Method: human gates.
Context
Why it matters
AI can produce analysis faster than people can check it. Fixed gates make sure a person with authority reviews the structure of the model, the decision itself and every change to a client's systems, so accountability never shifts to the software.
In practice
How strategy1 uses it
At H1 an ontology engineer confirms the Strategy Twin's structure before any option is built on it. At H2 the Strategy Council and, where liability exists, a Domain Fellow sign, and the client chooses. At H3 the client's named owner approves a dry-run of every change before anything is written to a client system.
FAQ
Human approval gates (H1, H2, H3): common questions
What does gate H1 check?
Gate H1 checks the model. At the Model stage an ontology engineer confirms the structure of the Strategy Twin before any option is built on it, so later analysis does not rest on a wrongly shaped model of the business.
Who signs at gate H2?
At gate H2, the Decide stage, the Strategy Council signs and, where professional liability exists, a Domain Fellow signs the parts they reviewed. The client then chooses. A decision memo is issued only after both approvals.
What happens at gate H3?
At gate H3, the Deploy stage, the client's named owner approves a dry-run of exactly what will change. Only then is the action written to a client system such as a CRM, a budget or a campaign tool, and the approval is recorded in a hash-linked audit trail.
