• Applied labels: release, 0.5.10, devnet5.
• PR checks are currently running; PR is mergeable but blocked on required checks.
• Scheduled watcher watch-zeam-release-pr-1048-devnet5 for 2026-07-17 17:16 UTC to merge when green and monitor the release workflow/image publication.

Expected after merge:
