Five Phase 1 criteria: Bug 2 closed (cap_pool readback returns real
pixels through libva); Bug 3 closed (hantro MPEG-2 + VP8 controls
accepted on new kernel); patches ship from kernel-agent (local-carry
acceptable, mainline bonus); zero codec-contract regression vs iter4;
5/5 direct-verification block restored.
