 I was rereading lately Paper Trail:

https://www.w3.org/DesignIssues/PaperTrail

Generalized form:

Generalizing for formal protocols
The concept of a paper trail is common in conventional administration, but
the model can also be applied to well-defined computer protocols.

Model
The model is that a protocol P defines a status sn as a function of a
message m and a previous state sn-1, and the time t.

sn= P(mn, sn-1, t)

or for that matter as a function of all the messages to date

sn= P'({mi}i=1..n)
