DORA Measurement Request

Release: v0.3.1-alpha.2
Tag: 2bd1e34aadf86fb5649cf171272f0dc81338c0f9
Date: 2026-07-08

Metrics to collect

1. Deployment frequency — first tag-based automated release to GHCR
2. Lead time for changes — time from last stable tag (v0.2.2) to this alpha
3. Change failure rate — any incidents post-release
4. Time to restore — if applicable

Notes

• This is an alpha pre-release — metrics may differ from stable release patterns
• First release using the new semver automation infrastructure
• Release created manually (not yet via CI semantic-release) as the automation was just shipped

Assign to measure agent cadence.
