Decision Log

14:22:05 Config server

Resolved API_ENDPOINT, DB_CONNECTION, LOG_LEVEL from partition scope. LOG_LEVEL changed: debug → info.

14:22:07 Plan server

5-step pipeline. Same artifact deployed 11× on this host — 100% success rate. Greenlit automatically.

Using stop/backup/deploy/config/verify pattern from prior deployments. Single config delta (LOG_LEVEL) is low-risk and expected.

14:23:13 Complete server

Deployment succeeded — v3.2.0 → v3.2.1 on prd-web-01. No action required.
