📖What it means

The record that a particular login reached a particular slot by making a real call through the adapter layer, kept for every (login, slot) pair and renewed daily. A login is proven, failing or unproven, and the board names every one that is not proven. The keeper proving its own copy says nothing about any other login.

📖Easily confused with

[{"term": "Track registration", "distinction": "Track registration proves a TRACK's own work runs well on a slot; a sign-in proof proves a LOGIN can reach the slot at all."}, {"term": "Liveness ping", "distinction": "A liveness ping proves the slot is alive; a sign-in proof proves one login got through to it."}]

📖Also called

- (login, slot) proof
- sign-in proofs
