crs:Flipped="true" is how Lightroom Classic writes an ordinary radial mask
(effect inside); it was read as our invert, so every imported radial applied
outside the circle. Established from Lightroom Classic 15.6's exports of
synthetic DNGs:
- MaskGroupBasedCorrections, Version 2: Flipped is the effect-inside flag;
inverting is the component's MaskInverted.
- MaskGroupBasedCorrections without Version: inside whatever Flipped says
(Lightroom rewrites both values as Flipped=true, Version=2), and its Feather
is halved, as Lightroom rescales it on that upgrade.
- Legacy CircularGradientBasedCorrections Radial Filter: outside by default,
Flipped=true (Invert Mask) is inside.
One mapping serves XMP sidecars, DNG-embedded XMP, presets and .lrcat catalog
import. LightCraft writes no crs: masks, so there is no writer to match.
