Explainers

The ideas the standards rest on, one page each: what the term means, a made-up case where it matters, what to look for in a real system, and which standards use it.

Three kinds of reversibility

Technical, operational, and institutional reversibility are separate claims, and only the third decides whether a correction will ever be used.

What is a burden index?

A burden index measures the minutes, retries, and documents a system demands from people who comply, challenge, or recover.

What is a permission surface?

The permission surface is the set of authority grants in force, each with an evidence basis, a scope, a state, and an expiry.

What is a safety valve?

A safety valve routes cases to a logged fallback path, often human review, when automation is overloaded, uncertain, or error-prone.

What is design authority?

Design authority names the accountable owner who can approve, change, or halt a system’s design.

What is stoppability?

Stoppability is the ability to halt an automated process: for the person inside it, without penalty; for the institution, by a named person, in a set time.

What is time to halt (TTH)?

Time to halt (TTH) is the time between a request to halt an automated system and the moment it stops acting.
