Runbook

Internal operations guide for BANA — for developers, ops/SRE, and support staff.

Internal use only

This runbook contains operational procedures, incident playbooks, and support workflows. Do not share outside the NEXPANDO team.

Sections

Section	Purpose	Primary audience
Deployment	How to deploy, roll back, and manage environments	Dev, Ops
Operations	Day-to-day checks: services, queues, DB, cache, logs	Ops, On-call
Incidents	Triage and playbooks for common alerts/outages	On-call, Ops
Support	Customer triage and common issue resolution	Support

Conventions

• Severity levels — S0 (outage), S1 (major degradation), S2 (minor), S3 (cosmetic).
• On-call — rotation and escalation are documented per section.
• Commands — every command block is copy-pasteable; placeholders use <angle-brackets>.

How to contribute

Runbook pages live under docs/wiki/content/en/runbook/. Keep entries short, recipe-style, and focused on the "what to do now" — link to the developer docs for deeper context.
