marfrit f15ba8b147 Phase 0 in-session re-verification: 2026-04-26 picture holds
Re-executed deliverables #1 (verify failure-mode finding) and #4 (capture
contract trace) on ohm against the substrate that's actually deployed —
not the libva-v4l2-request-fourier git fork master, but the
libva-v4l2-request-ohm-gl-fix package built on boltzmann from the Step 1
18-patch series.

Result: vainfo enumerates 7 H.264 + 2 MPEG-2 profiles cleanly; mpv
--hwdec=vaapi-copy decodes 68 H.264 frames end-to-end through the full
V4L2-stateless contract on hantro /dev/video1 + /dev/media0. Zero
EINVAL/EAGAIN/EBUSY on the request-API path. No rig drift requiring
Phase 2 loopback.

Inventory finding documented: the git fork at e8c3937 is a pre-Step-1
substrate; rebuilding from it as-is would be a regression. Step 1
reconciliation (deliverable #2) is upstream of any future build-from-fork
action.

Rig caveat captured: --hwdec=vaapi requires a real VO; --hwdec=vaapi-copy
is the headless-safe alternative for SSH-driven test rigs.
