**PR #<PR>** (linked #<ISSUE>). <one-line PR title>
**Mergeable:** <CLEAN | DIRTY conflicts | BLOCKED>
**Scope:** <+X/-Y, N files>
**Packet/diff verdict:** <addresses the packet | does not address the packet | needs more evidence>
**Live verdict:** <optional, or skipped: no baseline>
**Audit flags:** <locale-dependent | DOM-class selectors | section-mapping violation | missing tests | none>
**Recommended next step:** <merge | request changes | take over via maintainer-edits | no live check needed>
