Revision 08 · Changed
Exposure defined
Was
A one-line definition that measured operator time, and so duplicated Rework.
Now
Exposure: the AI-mediated adverse events that land on people, counted by class of harm and disclosed by position relative to the system.
What changed
Exposure now has a working definition, v0.1, and is the first condition with its own page: three positions, a matrix of harm classes, the errors funnel, liability without authority as the headline trend, and three open flags that ship unresolved.
The short form everywhere else on the site is: AI-mediated adverse events landing on people, by position and harm class.
Why
The previous one-line definition measured operator time and therefore duplicated Rework.
Exposure is the residual condition. Hours counts load, training counts investment, junior headcount counts the door closing and rework counts clean-up time. Exposure counts the thing none of the others can: harm that lands on a person.
