Feature flags are never cleaned up, so nobody knows which paths are live
Meaning the repeat outages, not the one-off hardware failure in March.

Scope: the services this team runs, not the whole platform.
Error budgets exist on a slide and nowhere else
The staging environment does not resemble production
The incident channel fills with people asking for status instead of giving it
Nobody owns the shared database schema
To be precise: this is about the process, not the person on call that night.

Alerts fire so often that on-call mutes them
I mean the pattern over the last two quarters, not a single incident.
