Reviewer empirically read rkvdec-hevc.c on boltzmann kernel-agent
tree. sps_max_num_reorder_pics is NOT read by rkvdec. α-13 would
match kdirect's wire bytes but produce no behavioural change.
CRIT-2: num_entry_point_offsets (libva hardcoded 0 at h265.c:356,
kdirect 22 from slice header parse) + PPS UNIFORM_SPACING flag are
the live candidates. BBB HEVC uses WPP (ENTROPY_CODING_SYNC flag
set in PPS) not tiles; 22 entry points = 23 CTB rows for 720p with
32-pixel CTBs.
Decision: land α-13 as wire-correctness hygiene (matches kdirect,
no regression risk), then α-14 for the actual fix.
