CI/CD Governance Hardening

Problem

Releases bypassed test gates, incident handoffs lacked structure, and postmortems were not actionable.

Solution

• Made lint, type-check, integration, smoke, and Lighthouse gates blocking
• Defined rollback drill cadence and release ownership model
• Standardized release report and incident evidence templates

Result

No accepted quantitative outcome is published for this case until independent evidence review remains pending.

Proof

Public workflow records exist, but independent evidence review remains pending; they are not presented as accepted proof.

Lessons & Tradeoffs

Stricter gates require more pre-release discipline; the effect and cost tradeoff in this case have not been independently accepted.
