Which interface carries the promise?
Book companion
Carrier
Carrier names where, through whom, or through what the promise is encountered.
Which person or system carries it?
Where can the carrier overclaim?
Exercise
Apply it before abstracting it.
List every carrier that presents the promise: app, email, AI answer, person, dashboard, notification, status label, or policy.
A companion page should produce a usable artifact: one signal, one promise, one carrier, one proof standard, one betrayal risk, and one repair owner.
- Best input
- A recent case, customer-facing status, support label, AI answer, approval, or handoff.
- Best output
- A one-page review that another person can understand without hearing the whole theory first.
- Stop condition
- If the team cannot name proof or repair ownership, that is the finding.
