Evidence
A checkable artefact of something actually done, attached to the record that claims it.
Evidence is the unit that replaces the proxy. A degree says a person attended; evidence says what they made. A job title says an employer agreed; evidence says what shipped.
Every piece carries its source, its date, its basis and its method of verification. Evidence with no source still renders — as unverified — because hiding weak claims is how systems become unreadable.
The economy runs on this: learning produces evidence, evidence unlocks work, work produces more of it. Reputation becomes a function of checkable history rather than of accumulated attention.
