Published v0.9.0 release evidence

The first stable release-candidate publication completed on 2026-07-31.

• Release: https://github.com/rsasaki0109/lidar_slam_ros2/releases/tag/v0.9.0
• Workflow: https://github.com/rsasaki0109/lidar_slam_ros2/actions/runs/30629881856
• Immutable tag: v0.9.0
• Tag commit: 0df0c4a86df9f68a894c83f8342e4107c3d23b0f
• Workflow conclusion: success
• Release state: final, stable (draft=false, prerelease=false)

The tagged workflow built, attested, and smoke-tested the Humble and Jazzy amd64 images by digest before promoting their immutable version tags. It then published and independently audited these six recovery assets:

• lidarslam_ros2_v0.9.0_release_bundle.tar.gz
• release-image-humble.json
• release-image-jazzy.json
• release-promotion.json
• rollback-plan-humble.json
• rollback-plan-jazzy.json

After publication, the following read-only command completed with Published release audit: PUBLISHED:

python3 scripts/check_published_release.py --require-published

Every contract check passed: immutable tag identity, stable release state, required assets, cross-asset source and image identity, embedded release bundle hashes, rollback records, promotion record, and live Humble/Jazzy GHCR version-tag digests. This evidence closes the reliability and stable v0.9 release-publication readiness gates; it does not close ROS apt distribution or independent-user adoption.
