LR-IMP-FORMATS: verify 22 more CR3 bodies; EOS R6 Mark III white balance
All 110 CC0 CR3s on raw.pixls.us decode from sensor data; none uses a refused CRX variant. One CC0 file per further body (1D X III, 90D, 250D, 850D, M200, M50 II, M6 II, R, R3, R5, R6, R6 II, R6 III, R7, R10, RP, R50, R50 V, G5 X II, G7 X III, SX70, V1) is added to RAW_SAMPLES and pinned in cr3_corpus.rs, checked against the camera's embedded JPEG. The R6 Mark III writes ColorData version 66, laid out as 64/65; it lost its as-shot WB and white level. Render cache 61 -> 62. Also: as_chunks in spots.rs for the chunks_exact_to_as_chunks lint. Docs: evidence.tsv + coverage re-measure (257 verified, 92% use-weighted), gaps 2/10, checklist rows, raw-parity, target-app-parity, ROADMAP, README. Sources: own black-box analysis of CC0 files; ExifTool Canon tag tables. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
