Fitted with `lightcraft-cli calibrate` to 144 usable ILCA-99M2 ARWs (of
150, seven shooting days, Standard creative style, DRO Auto) and their
in-camera JPEGs; aggregate colour statistics only.
On 30 withheld photos (profile fitted to the other 120) mean dE76 against
the camera JPEG goes 5.11 -> 4.87; 25 of 30 improve, the worst
regression is 0.24. All 150 photos stay accepted. The public raw.pixls.us
ILCA-99M2 file, not used for fitting, stays accepted (5.57 -> 5.73).
A corpus test checks that this public sample's fit keeps exactly the
built-in profile's matrix and table; the ILCE-7CR test now shares its
body. LOOK_VERSION 5 -> 6, as the profile changes the fit of this model.
Fitted with `lightcraft-cli calibrate` to 125 usable ILCE-7CR ARWs (of 131,
September 2025 to September 2026, Standard creative style) and their
in-camera JPEGs; aggregate colour statistics only.
Without it, 8 of the 131 photos fail the fit gates and open with the
neutral matrix (dE76 6-26 against the camera JPEG). On 26 withheld photos
(profile fitted to the other 105) mean dE76 goes 4.07 -> 3.29 and both
withheld rejections are accepted (26.0 -> 6.1, 6.2 -> 5.5); the 24
withheld photos whose own fit was accepted are about unchanged (12
improve, mean 3.06 -> 3.08, worst regression 1.8). With the final profile
all 131 are accepted. The nine public raw.pixls.us ILCE-7CR codings stay
accepted (mean 1.59 -> 1.99).
A corpus test checks the public lossless-L sample's fit keeps exactly the
built-in profile's matrix and table.

A built-in Sony ILCE-7M4 colour profile (assets/camera-profiles/ILCE-7M4.json, compact JSON, 39 KB), fitted by lightcraft-cli calibrate to the contributor's own 597 raw photos against their in-camera JPEGs; aggregate colour statistics only, MIT OR Apache-2.0. Compiled in via camera_profiles::BUNDLED; a local profile replaces it.
