WalkthroughThe change adds shipment MR reuse, replacement, validation, and full file reconciliation to both release pipelines. Non-dry-run layered-product shipment preparation now uses a group-and-assembly lock. Reused MRs reset to draft and retain their configured assembly pointer.

Suggested reviewers: Merge Risk: 🔵 Low · up to Shipment reruns now reuse existing merge requests. The remaining low risk is duplicated validation logic across both release pipelines, which could make future safety checks inconsistent; merge is reasonable with follow-up. Important Pre-merge checks failedPlease resolve all errors before merging. Addressing warnings is optional. ❌ Failed checks (1 error)
✅ Passed checks (10 passed)
Full details: No-Sensitive-Data-In-LogsExplanation The PR adds logging of full shipment MR URLs. For example, Resolution Do not log complete MR URLs. Log only a non-sensitive identifier such as the assembly and MR IID, or omit the URL entirely. Ensure dry-run, reuse, creation, and completion messages use the same redaction. Also sanitize any exception or validation message before sending it to a logger so URL userinfo, query data, or fragments cannot expose credentials or tokens. ✨ Finishing Touches🧪 Generate unit tests (beta)

location, or otherwise use the repository-aware path for mkdir, while preserving
the existing relative path passed to write_file.

ValueError from get_file_from_branch when releases.yml is missing or unreadable,
matching _get_main_ocp_shipment_url by returning None and leaving the configured
shipment URL unset so layered-product --create-mr runs can continue.

Summary
Layered-product releases now reuse the shipment merge request recorded in
releases.ymlinstead of creating a new MR on every run. This works for bothprepare-release-lpand the directrelease-from-fbcpath.On reuse, ART rebuilds the shipment files from the current job inputs. Reuse is allowed only when staging is no longer running and production has never been attempted
