Promotion gates that make Friday deploys boring

Environment parity checks and rollback drills that turn late-week releases from drama into routine.

Friday deploys feel risky when staging diverges from production in quiet ways: different feature flags, older migration state, or a missing sidecar. The pipeline reports green while the environments disagree.

We add promotion gates that compare config fingerprints, migration version, and critical sidecar images before a production approval button appears. Failures stop the promote step with a readable diff, not a generic error.

Rollback drills happen on a schedule, not only during incidents. A ten-minute reverse path rehearsal once a month surfaces missing permissions and outdated runbooks before they matter.

Boring Friday deploys are the point. Drama belongs in product discovery, not in the last mile of the release lane.
