Epic column) with a real Jira epic ID and its corresponding URL; if there is no
epic yet, explicitly set the Epic cell to "None" and remove or replace the link

locate the mismatched strings ("Supporting backport changes for releases" and
the metadata table) and ensure the title and metadata align with the document's
actual subject and navigation placement.

⚠️ Potential issue | 🟠 Major

Topic metadata is inconsistent with the document location.

Line 1 and the metadata describe supporting backport changes for releases, but this file is under low-overhead-deployment-for-server-mode. This makes the doc’s purpose ambiguous and likely misclassified in docs navigation.

Internal doc link appears to target the wrong directory.

Line 10 points to docs/design/supporting-backport-changes-for-releases/, which does not match this document’s path. Please update it to the canonical location to avoid a broken/stale reference.

⚠️ Potential issue | 🟠 Major

Core design sections are empty, so the spike is not reviewable yet.

What, Why, Requirements, Use Cases, and Solution are currently placeholders. This is too incomplete for a design artifact intended to guide implementation and scope.

Placeholder epic ID should be resolved before merge.

LCORE-???? and its link are placeholders and not actionable. Replace with a real epic ID (or explicitly mark “None” if not created yet).
