[edera-rebase-app]

Nightly rebase of edera/mainline (a85e73be200d) onto master (b3dfbde62cf1), driven by Claude. Not pushed automatically because the checker found drift. Run log.

Important

Do not use the merge button: this branch replaces edera/mainline rather than merging into it. Approve the pull request to land it; the land workflow force-pushes edera/mainline to the approved head, pinned to a85e73be200d, and keeps a backup.

Independent checks

Builds: success (x86_64 vmlinux on the Edera host config and arm64 vmlinux, both with the Edera features built in; per-build results in the run).

Old tip	a85e73be200d
New tip	2c5c9e64ba04
Old upstream base	864c07de0c7d
New upstream base	b3dfbde62cf1

• New branch is based on the upstream tip.
• Downstream series is linear.
• Downstream commit set changed: 114 before, 114 after; 1 commit(s) lost, added, or with different +/- lines.
• Downstream drift: the tree changed by more than the upstream delta.

Commits whose hunk context moved (own +/- lines identical)

• ea62ac9f1b0f iommu/xen: Add Xen PV-IOMMU driver → f3a50eb1fad4
• bd1c0dba57c3 sysctl: wire up PaX softmode setting → 420676e359bc
• 849ed61740ea use maximum supported mmap rnd entropy by default → 3c6ca4feedc4
• 5b1ff5bbc8cb 9p/xen: carry the 9P session across a restore → 2995c63204fc

Commits lost, added, or whose own +/- lines changed

Claude's report

Claude left no report (rebase step: success).

The rebase is done and both builds pass. Four read-only agents are now auditing the upstream changes that touch series files (mm/OpenPaX, Xen/9p, Hyper-V, IOMMU). I'll write the report once they finish.
