Three submission drafts, written and parked, awaiting validation gates. All live in gitea/marfrit-packages under upstream-submissions/.

Index: fourier.

• File: upstream-submissions/qt6-base-fourier/qt-bug-report.md
• Targets: bugreports.qt.io issue + Qt Gerrit MR
• Why now-ish: pure spec-correctness GLES3 fix, validated on two Mali generations (G52 ohm, T860 fresnel), zero regressions visible. Cleanly upstream-targetable.

• File: upstream-submissions/kwin-fourier/kde-mr-body.md
• Targets: KDE GitLab (invent.kde.org) merge request against kwin
• Patch: 0002-transaction-poll-dmabuf-fd-directly-upstream-shape.patch
• Why staged: the diagnostic patch (0001) is a bypass not suitable for upstream; 0002 is the upstream-bound shape (poll dmabuf fd directly instead of going through EXPORT_SYNC_FILE + QSocketNotifier).

• File: upstream-submissions/vb2-dma-resv/lkml-submission-notes.md — full git send-email recipe with CC list
• Source: kernel/vb2-dma-resv-rfc/
• Target: linux-media mailing list (RFC)
• Patches: vb2 helper API + hantro opt-in + rockchip-rga opt-in
• APIs verified: all against include/linux/dma-{fence,resv}.h

See fourier:vb2_dma_resv_rfc for why this exists and how it relates to the kwin patch.
