Diagnostics and logging

Development reference · View source

Four surfaces answer four different questions:

SurfaceAnswers
Interaction lineWhat did the last command do?
:notificationsWhat happened in this workspace? (bounded, in memory)
:service-healthWhat state are optional services in right now?
Diagnostic logWhat went wrong, even after Runyte is gone?

The diagnostic log is a small local file that outlives the process. It is not a second notification system and not an audit trail: an actionable failure still reaches you through the ordinary surfaces whether or not a record was written.
