Coordinated update review evidence — a42ae4a

Evidence for PR #32495, reviewed source a42ae4a0afab372ba8533280639d68a86fa551ff.

This prerelease contains verification evidence only: report, sanitized receipt, source manifest/patch, recording, screenshots and checksums. It contains no installable build or runtime userdata.

172 tests in 19 files and all changed-file checks passed. Claude Opus 5.5 high passed final source/evidence review. The Linux x64 fixture updated provider and managed server before installing the desktop, then automatically relaunched and reconnected using its saved credential. See the report for source-to-artifact mapping, earlier inconclusive checker result and test limits. Maintainer scope approval and merge remain pending.
