Runbooks and memory

Runbooks and memory holds, for each service, what the investigator should know.

• Runbook: lines your team writes, such as “Errors after a deploy usually mean a missing migration” or “Page the payments team for anything on ledger”. Add and remove lines on the page. Each line keeps who added it and when.
• Memory: what the agents wrote down in earlier investigations, shown below the runbook, newest first.

The investigator reads a service’s runbook on its next check, and its memory on every investigation, so each incident starts from what the last one learned.
