EOS R6 Mark II C-RAW QP maps reach 172 and 175; crx.rs accepted 131-168,
so those files opened as their preview ("Canon CRX adaptive QP value 172").
Adaptive QP now goes to 175 (quantization value 51, step 228), the highest
seen in any file; uniform subband values still stop at 44.
Checked black-box against the camera JPEGs on private files: 144 R6 II /
R7 C-RAW files decode to identical hashes where they decoded before, the 3
failing ones now decode (green follows the JPEG at r 0.98), fine detail per
QP shows no jump at 172/175, 100 % crops are clean, and 1,492 files sampled
from a 35,796-file library decode with max QP 175. No third-party decoder
source consulted. Bumps RENDER_CACHE_VERSION to 63; cr3.md and What's New.
