Audit Trail
An immutable, time-stamped record of who decided what, when, and on the basis of which evidence.
Audit trails matter for three reasons: regulator inquiries, internal succession, and board oversight. The standard is reconstructibility - any decision should be re-creatable from the underlying record without relying on anyone's memory.
This is achievable only when the workflow captures evidence at the moment of action, not after the fact.
