OpenCode Dependabot Risk Review

Schema: local-stack.dependabot-risk.v1

Decision: NEUTRAL
Risk: LOW
Automerge allowed: false
Update type: semver-patch
Ecosystem: docker

Summary

Renovate PR updates grafana/loki from 3.7.5 to 3.7.6 (patch). The source compose file and three generated stack files are modified. Loki is a stateful service requiring extra scrutiny. Generated stacks are changed with matching source changes, so the REQUEST_CHANGES condition for orphaned stack edits is not triggered. However, deployment files (stacks/*.yml) are modified, which blocks unconditional APPROVE per policy. No release notes context is available to confirm absence of migration risk for this stateful service.

Changed runtime artifacts

Image / dependency	From	To	Risk note
grafana/loki	3.7.5	3.7.6	patch update for stateful service loki; no release notes available to confirm absence of migration changes

Runtime impact

Expected rolling service update for loki. Generated stacks will be redeployed. Stateful service (loki) may require volume/data compatibility verification.

Breaking change assessment

No release notes context available; patch bump from 3.7.5 to 3.7.6 is unlikely to contain breaking changes, but cannot be confirmed without release notes.

Required checks

• ./stackctl.sh sync
• ./stackctl.sh up --dry-run --no-logs

Manual follow-up

• Verify loki 3.7.6 release notes for any migration or config changes
• Confirm generated stack diffs are consistent with the source compose change only
