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.
Named sets of local adjustment sliders, picked from a new Effect menu
above the mask sliders in the Masking panel (apply sets every slider and
keeps Amount; save current; import; right-click delete; the menu names
the matching effect, else Custom). Saved with the library preferences.
Commands: mask.effects, mask.applyEffect, mask.saveEffect,
mask.deleteEffect, mask.importEffects, mask.exportEffects (.lceffect).
Lightroom local adjustment presets (.lrtemplate with type
LocalizedAdjustmentPreset) are read by mask.importEffects and routed
there by preset.import / File > Import Profiles & Presets, which used to
reject them as having no develop settings. Their lower-camel Local* keys
map through the same table as XMP mask fields (crs_masks::local_values);
sliders without a counterpart (toningLuminance, grain) are reported.

Heal and clone spots stored as crs:RetouchAreas (Mask/Ellipse, Mask/CircularGradient
or a brushed Mask/Paint target; SourceX/OffsetY as the source's absolute position,
honoured only when the source was set explicitly; Opacity and Feather 0..1) and the
legacy crs:RetouchInfo list become our spots when a sidecar, embedded XMP, XMP preset
or .lrtemplate is read. Width fractions are converted to long-edge fractions with the
target's aspect, like radial masks. Unsupported spot masks are reported as
`Spot: <kind>`. Format established by observing what a sidecar written for a healed
photo contains; clean-room.
Tests: heal with explicit source, clone with automatic source, brushed removal,
circular-gradient spot, unsupported mask reported, portrait-target scaling, legacy list
on its own, and a render test. docs/xmp-interop.md gains a Spot removal section;
LR-META-XMP row updated.

A Custom white balance from a Lightroom catalog or XMP sidecar was taken as absolute Kelvin for every
raw. Raws LightCraft develops relative to their as-shot look (ARW, NEF, RW2, RAF, CR3, CR2, PEF; 6500 K
means as shot) then read a small tweak as a large blue shift: ΔE 22 against Lightroom's export on the
photos of issue #510.
The crs mapper now takes a `Target` (preset, rendered, raw with a measured illuminant, relative-WB raw)
instead of a bool. For relative-WB raws, and rendered files with only `Temperature`, a Kelvin value is
converted to the same mired shift from the packet's `AsShotTemperature` / `AsShotTint`. Without that
reference (Lightroom catalogs keep none for Custom photos) the photo stays As Shot and the import
report lists `Temperature, Tint` as not carried over. Import, sidecar read and catalog import decide
the target the same way through `lightcraft_catalog::relative_wb_format`.
Tests: shift from the issue's numbers (3650 → 3578 K lands at ~6275 K), the As Shot fallback with its
report entry, target selection per file, and the catalog mapper's Custom-WB case.
Local corrections stored as crs: structures (MaskGroupBasedCorrections and the older
gradient / circular gradient / paint containers) become our masks: linear and radial
gradients, brushes (dab runs → strokes), Subject / Sky, luminance and depth ranges, with
add / subtract / intersect and invert, and all local sliders. lightcraft-meta's XmpData gains
`values`, a structured view of every property (arrays of structs survive); .lrtemplate Lua
tables convert into the same shape.
Applying a preset adds its masks to the photo's own (once; Amount scales them); sidecar masks
replace them and radial masks are fitted to the photo's aspect. Unsupported components
(colour range, other AI selections) are reported as "Mask: <kind>".
