AHD chose the horizontal or the vertical candidate outright by the larger 3×3 homogeneity sum. In a flat, noisy
area noise alone decides which is larger, so the picture became short horizontal and vertical strokes (a maze,
orange and blue under strong white balance) that noise reduction then made stand out. It now blends the two
linearly while their sums are within 12 of each other (of 36), and takes one alone beyond that.
On an ISO 4000 ILCE-7CM2 ARW under tungsten light the maze measure of a flat region drops ~30 %; PSNR on the
synthetic smooth and edge scenes is unchanged or better (73.0 → 73.7 dB, 37.7 → 37.9 dB). The colour part of the
pattern mostly comes from demosaicing before white balance (#1328, PR #1463), which this does not change.
New test flat_noise_does_not_turn_into_a_maze fails on the outright pick. RENDER_CACHE_VERSION 70.
docs/parity-checklist.md: header keeps the newer date; LR-IMP-FORMATS row keeps both sides' changes.
docs/raw-parity.md: header change note names both sides' changes.
docs/raw/coverage.tsv: merged cleanly; same rows as both sides, no duplicates (regenerated on the combined branch).
crates/raw/src/kelvin_presets.rs: covered_models keeps the Z5II asserts (#2006) and the Canon cases (#2009).
docs/parity-checklist.md: LR-EDIT-COLOR-TEMP row keeps both sides' preset clauses.
crates/ui-egui/src/tests_grid.rs: both sides' tests
docs/whats-new.md: both entries under one 2026-10-16 heading
docs/parity-checklist.md: header and revision rows from both sides
crates/engine/src/camera_preview.rs: LOOK_VERSION keeps both history lines and the higher value.
crates/engine/src/media.rs: RENDER_CACHE_VERSION keeps the higher value.
docs/whats-new.md: both 2026-10-14 entries under one heading.
crates/engine/src/media.rs, crates/engine/src/smart.rs: DecodedSource keeps both new fields, from_proxy (#1809) and reduced (#2263); a smart preview loads with from_proxy true, reduced false.
crates/engine/src/cmd/previews.rs: original_only refuses both proxy-loaded and reduced sources.
crates/ui-egui/src/panels/grid.rs: badge keeps main's double-click guard and calls #2300's toggle_stack
crates/ui-egui/src/tests_grid.rs: both sides' badge tests
docs/parity-checklist.md: header and revision rows from both sides; rows take both changes
docs/parity-checklist.md: LR-IMP-FORMATS row keeps main's DNG/Hasselblad text and adds #1165's SR2/SRF phrase; revision rows are the union
docs/raw-parity.md, docs/gaps.md: revision rows are the union
crates/ui-egui/src/panels/detail.rs: #2317's split (info_overlay / info_overlay_lines / info_overlay_extent) kept; info_overlay_lines builds its lines from #1965's View Options fields (info_line) and returns None when off or when no line is left
crates/ui-egui/src/panels/dialogs.rs: only_shows keeps Dialog::ViewOptions and the up-to-date Synchronize Folder case
crates/ui-egui/locales/it.json: union of keys
Conflicts:
- crates/ui-egui/src/i18n.rs, crates/ui-egui/src/menus.rs: language table and commands keep every language plus vi

crates/engine/src/camera_preview.rs: LOOK_VERSION keeps both history lines and the higher value.
crates/engine/src/media.rs: RENDER_CACHE_VERSION keeps the higher value.
Conflicts:

crates/engine/src/camera_preview.rs: LOOK_VERSION keeps the higher value; fit_tone_only_pairs (from #1616) takes the HighlightCheck of #699 from fit_tone_only_on, and fit_dark_tone passes its frame's (empty, as no JPEG pixel reaches 0.85) check.
crates/engine/src/media.rs: RENDER_CACHE_VERSION keeps the higher value.
docs/parity-checklist.md: LR-PROF-CAMERACOLOR row keeps both sides' changes.
crates/ui-egui/src/tests_zoom.rs: both new Before-label tests, with #1968's comment wording on the crop test
