Nikon bodies from before ~2016 record no CropArea, so the decoder kept
their whole sensor data, less trailing dark columns. Where that data
holds masked lines above black or optical black, they were developed as
a coloured or dark bar on that edge: the D7000 and D5100's 36 columns at
~600 (#976), the D800's 14 (#914, the top in portrait), the D600 / D610's
8 (#1236), the D3200's 46, and others.
MEASURED_BODIES (crates/raw/src/vendor/nef.rs) now gives 44 more model /
data size / depth groups the frame of their camera JPEG inside the data,
next to the D4, D7100 and D90 entries already there: D7000, D5100, D800,
D800E, Df, the D4's 12-bit mode, D3, D3S, D700, D300, D300S, D600, D610,
D810, D4S, D5600, Coolpix A, D3000, D40X, D60, D80, D2Xs, D200, D3200
and Nikon 1 V1; and, on best-guess frames short of the evidence rule,
each with a comment naming its evidence, the D3100 (3 of 4 clean files
agree), D5000 (4 of 5, and the D90's sensor), D40 (2 of 2), D50 and D70
(one file each, agreeing) and D70s (next to them, between pixels).
Every best-guess frame keeps the masked lines out by several pixels.
An entry matches model, data size and depth exactly. Bodies whose data
holds only picture beyond the camera frame get no entry and render as
before.
`cargo xtask raw-frame FILE...` (crates/engine/examples/raw_frame.rs)
measures a body: it aligns each raw's embedded camera JPEG with the
sensor data (half-size luminance, gradient correlation, sub-pixel peak;
weak, ambiguous or between-pixel peaks are flagged), counts the edge
lines that hold no picture and reports what the decoder's crop keeps
beyond the camera frame. A masked line is flat and its two CFA phases
agree within the noise or within 0.4% of white, so filler with a small
fixed offset between them (D90, D5000) counts. It prints entries only
with evidence: at least 3 clean files agreeing exactly, of the model
(12- and 14-bit pooled) or, with at least one of its own, with sibling
models of the same readout (data and JPEG size) that agree on the same
frame. On the D7500, which records its CropArea, it finds that area
exactly; it declines the Z f, whose JPEG is distortion-corrected. It
works for any make whose raw embeds a full-size camera JPEG: on Sony,
Canon CR2 / CR3, Pentax and Samsung files it finds the decoder's own
crop (relative to the active area).
Every Nikon raw on raw.pixls.us without CropArea was surveyed this way
(its 138 CC0 samples, plus 124 other publicly posted sample files; only
the measurements are committed). Bodies whose data holds only picture
beyond the frame need no entry (D750, D5300, D5500, D3300, D2X, D2Hs,
D3X, D5200, Coolpix P6000, Nikon 1 AW1 / J3 / V2 / V3, the D800's crop
modes); raw-parity.md lists them, and no longer claims every NEF
coding but HE decodes. measured_bodies_are_consistent checks every entry lies
inside its data and is listed once; measured_older_dx_bodies_image_area
covers the D200, D3200, Nikon 1 V1 and best-guess entries.

The D90 writes 4352 x 2868 samples whose last 42 columns (from 4310) are
filler at a flat ~254, above its dark image samples (black 0). The
masked-column test only trims columns near zero, so they stayed in the
image and developed as a pink band on the right. Measured on 10 of 550
NEFs from one body: the camera's 4288 x 2848 JPEG sits at (10, 10), and
green saturates at 3840-3851 while red and blue run on to 4095, so one
white level of 3830 keeps clipped highlights white. The D90 joins the D4
in MEASURED_BODIES; other bodies are unchanged.

Sony ARWs of cameras without measured colour matrices were edited on the
relative scale (6500 K / 0 = as shot). Their SR2SubIFD stores the
multipliers of the camera's presets at 2500, 3200, 4500, 6000 and 8500 K;
lightcraft_raw::kelvin_presets reads the as-shot multipliers on the curve
through them and they take the spectral matrices' place in the #730
design (as-shot Kelvin and tint only; look, Bradford adaptation and the
pixel-identical legacy upgrade unchanged).
Covered: ILCA-99M2, ILCA-77M2, SLT-A33, DSC-RX10, ILCE-3500, ILCE-7S.
Kelvin-dial shots read back 3400 -> 3396, 5200 -> 5193, 4700 -> 4708,
5600 -> 5594 K; Shade 7493 K. Off-curve constants (isotherm tilt 0.74,
tint spacing 1) measured from the 14 Sony bodies with both spectral
matrices and presets.

An uncompressed Leaf Aptus 22 MOS keeps its 16-bit mosaic in IFD0
(compression 1, BlackIsZero, one sample per pixel) with no Make tag and
no CFA photometric, so `probe` returned None and the file imported as a
greyscale image of the mosaic. Leaf's data block, tag 0x8606 (LeafData
in the ExifTool EXIF tag-name documentation), now marks such an IFD0 as
a raw: OtherTiff, preview only with the reason, as the lossless-JPEG MOS
already is. A rendered RGB image that kept the block stays an image.
The Hasselblad Lunar is a Sony NEX-7 that writes an ARW under Make
HASSELBLAD; only SONY files reached the ARW reader, so it opened as its
preview. A HASSELBLAD file with Sony's raw coding (an IFD with
compression 32767 or the tone-curve tag 0x7010, which no 3FR / FFF has)
now goes there and decodes like a NEX-7: black 512, the SR2SubIFD white
balance. The Tag2010 white-balance fallback, the one table arw.rs keys
by model, takes the body from the maker note's SonyModelID (0xb001)
when the file is not Sony-branded.
Docs: the Lunar is verified in docs/raw/evidence.tsv (236 verified),
raw-parity.md, parity-checklist.md, gaps.md and whats-new.md.
RENDER_CACHE_VERSION 61 -> 62: a Lunar's thumbnails were rendered from
its preview.

All 38 files decode from sensor data and develop at full size (9520x6336 and
6336x9520) without error; mean CIE76 dE to the camera JPEG is 6.3-13.9 at 400 px.
The files are not committed and the evidence entry carries no path. Leica is now
14 verified / 47 unverified, the Leica bucket on a verified body 5% -> 21%; the
weighted shares (85% decode, 42% on a verified body) do not move.

The CRX 0x200 QP map opens with its first symbol as a 32-bit literal; every
later symbol is Rice coded with a limited-length escape: 23 zeros, the
terminating 1 and the symbol in 8 bits (the ITU-T T.87 layout for a 32-bit
limit and 8-bit symbols, without its minus-one offset). The old rule (an
escape after 16 zeros with a 16-bit literal) matched only the first symbol,
which is all the R8 and R7 maps need. R5 Mark II maps (QP 150-162) jump by up
to 12 where the Rice parameter is 0, giving 18- to 22-zero prefixes that
misparsed ("Canon CRX adaptive QP value -21087"): 174 of 306 sampled files
from a private R5 Mark II library opened as previews. Every QP map of its
33,665 C-RAW files now decodes to the exact end of its entropy stream; the six
oracle fixtures are unchanged. Established by black-box analysis of the
bitstream; no third-party decoder source consulted.
Adds the four CC0 R5 Mark II samples (raw.pixls.us 7881-7884) to the corpus
with pinned sensor hashes (the crop-mode framing is left to #754), bumps
RENDER_CACHE_VERSION to 43, and updates cr3.md, raw-parity (235 verified
models), coverage, gaps, the checklist rows, ROADMAP, target-app-parity and
What's New.
