Subject: [PATCH 2/5] Refactor logging to use consistent logrus style across
 the repository

- Replace log alias (log "github.com/sirupsen/logrus") in mlflow package
  with direct "github.com/sirupsen/logrus" import
- Convert all log.Printf/log.Println calls to proper logrus level methods
  (logrus.Infof, logrus.Debugf, logrus.Errorf, logrus.Warnf)
- Add consistent "mlflow:" prefix to all mlflow log messages matching the
  existing "component: action" pattern used across the backend package
- Replace stdlib log.Fatal with logrus.Fatal in cmd/root.go
- Remove unused stdlib "log" import from cmd/root.go

From: "copilot-swe-agent[bot]" <198982749+Copilot@users.noreply.github.com>
Date: Tue, 3 Mar 2026 02:30:21 +0000
Subject: [PATCH 3/5] refactor: optimize log messages for consistency and best
 practices

- Use concise, action-oriented messages (remove verbose "starting...operation" phrasing)
- Remove redundant "successfully" from completion messages (success is implied)
- Move config/struct dumps (%+v) from Info to Debug level
- Move internal operation details (digest calculation, cache hits, metadata) to Debug
- Add consistent component prefix to all logs (builder:, codec:, remote:, progress:)
- Use natural English phrasing (e.g., "pulling artifact" not "starting pull operation")
- Standardize wording patterns across all backend operations

From: "copilot-swe-agent[bot]" <198982749+Copilot@users.noreply.github.com>
Date: Tue, 3 Mar 2026 02:32:45 +0000
Subject: [PATCH 4/5] refactor: use verb-noun order in completion log messages

Address code review feedback: completion messages now use natural
"verb noun" order (e.g., "pushed artifact" not "artifact pushed")
for better readability and consistency with start messages.

Subject: [PATCH 5/5] revert: restore original log levels while keeping
 improved wording
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Revert all log level changes (Infof→Debugf) back to their original
levels. The wording and structure improvements are kept, but the log
levels now match the original code.

Files updated:
- pkg/backend/attach.go (3 Debugf→Infof)
- pkg/backend/build.go (2 Debugf→Infof)
- pkg/backend/build/builder.go (4 Debugf→Infof)
- pkg/backend/processor/base.go (1 Debugf→Infof)
- pkg/backend/pull.go (1 Debugf→Infof)
- pkg/modelprovider/mlflow/downloader.go (2 Debugf→Infof)
