| Type | Review required | Staging | Canary | Rollout window |
|---|---|---|---|---|
| Security patch | Light (1 reviewer) | Yes | 1 site | Within 7 days |
| Bug fix | Normal (2 reviewers) | Yes | 1 site | Next business day |

== RFC template ==

Every change should document:

* '''What''' is changing and why
* '''Risk assessment''' — what could break
* '''Rollback plan''' — how to undo
* '''Impact scope''' — which sites/nodes are affected
* '''Testing performed''' — what was validated in staging
* '''Monitoring''' — what to watch during rollout

== Approval gates ==

# Peer review (code/infra team)
# Hub admin sign-off (if clinical impact is possible)
# Ops lead approval for fleet-wide rollout
