The Error Budget Contract
Symptom Log
budget_status.txt
TARGET: 99.9% Uptime (43m / month budget)
CONSUMED: 44m (102%).
STATUS: BUDGET EXHAUSTED.
# ACTION: Feature Freeze Active. Focus on stability tickets.In SRE, an 'Error Budget' is the amount of downtime your business is willing to tolerate. Once the budget is 100% consumed, all non-emergency feature rollouts are stopped until the reliability score is restored.
This policy eliminates the conflict between Devs (who want to ship fast) and Ops (who want stability). The data speaks for itself.
Automated Governance
Integrate Watch.dog SLO Reporting with your CI/CD. If our monitors show that your error budget for the month is below 10%, we can automatically block deployments via our API.

[INFO] Please resolve existing incident #712 first.The Incentives Alignment
A formal budget policy encourages teams to build self-healing automation. If the automation prevents an outage, the budget isn't spent, allowing the team to ship more features.
Error Budget Triage
| Budget Remaining | Development Mode | Watch.dog Level |
|---|---|---|
| 80% - 100% | Full Innovation Speed | Balanced Monitoring |
| 20% - 79% | Caution / Observability Focus | High-Signal Alerts |
| < 20% | Stability Only / Bug Fixing | Elite Alert Escalation |
| 0% (Exhausted) | FEATURE FREEZE | Incident War-Room Active |
An Error Budget is not a failure; it's a tool for decision making.
