The localization layer was hardcoded to English and Japanese: an enum with two
variants, an `is_japanese()` gate compiled into the format macro, and one
catalog pair. Adding a language meant editing the menus, the settings row, the
checkmark logic, the format macro and the font stack — each in a different place.
A language is now one entry in `i18n::language_table!`: BCP-47 code, endonym,
ISO 15924 script and catalog. The Language menu, the settings row, the shortcut
sheet and the control channel are all built from that table, and `build.rs`
picks up `locales/<code>-formats.json` by name, so a further language is a table
entry plus two catalogs (docs/localization.md).
Simplified Chinese (`zh-hans`) ships as the second translation: `zh-hans.json`
(1019 entries, key-set and placeholder-identical to `ja.json`) and
`zh-hans-formats.json` (102 entries). Its glyphs come from craft-fonts' Noto
Sans CJK SC, whose `Hans` faces the UI now installs *before* the Japanese ones
for a Chinese reader, so shared Han characters keep the language's forms
(`fonts::cjk_fallback`); the export watermark accepts every CJK face.
`tr_format!` keeps its compile-time check. It formats the English source at the
call site — a runtime template cannot be handed to `format!` — and names those
values so a translation can place them by name (`{n}`) or position (`{_1}`).
Every translation is still checked by `format!`, so a translation with an
unknown placeholder fails the build. The Japanese catalog was rewritten from the
old `{:.0}` plural-discard trick to that by-name form; behaviour is unchanged.
Also: settings persist the BCP-47 code (never the Rust variant name),
`LIGHTCRAFT_LANGUAGE` accepts system-style tags (`zh_CN`, `ja_JP.UTF-8`),
`xtask parity` reads the second command table, and the glyph tests cover every
catalog character plus the interface symbols (`▸`/`▾` turned out to have no
glyph in any installed font and are gone from the Chinese text).
Chinese and Japanese both need `CRAFT_FONTS_DIR` as before; the web build still
embeds only the Japanese face (Noto Sans CJK SC alone would push the wasm past
Cloudflare's 25 MiB per-file cap), documented in docs/localization-zh-hans.md.

CR3 files imported as preview-only with the 1620x1080 PRVW JPEG and no metadata
(no camera, capture time, exposure, lens or GPS): nothing read the container.
- crates/meta/src/cr3.rs: bounded ISO base media box parser for CR3 (Canon uuid
box with CMT1-4 and THMB, tracks with their sample entries, CMP1 coding header
and sample location, XMP uuid box). Every size/offset checked; depth and box
count bounded.
- Metadata: CMT1 (IFD0), CMT2 (Exif) and CMT4 (GPS) merged into one TIFF Exif
block, so CR3 reads like any TIFF-based raw; XMP from its uuid box.
- Preview: the full-size JPEG track (6960x4640 on an EOS R6 Mark III) before
PRVW/THMB; imports report the full image size.
- Tests: synthetic CR3 (boxes, tracks, merged Exif), truncation/corruption sweep,
JPEG track preferred over PRVW with fallback.
Raw (CRX) data is still not decoded; CR3 stays preview-only.
LightCraft has no colour matrix for Nikon cameras. Because of this, NEF
files showed colours that were too gray and too green.
- Colour: LightCraft now calculates a colour matrix and a tone curve from
the JPEG preview in each NEF file. Sony ARW files use the same
procedure and the same quality checks. White balance is relative to
the as-shot look, as for ARW files.
- One function, camera_preview::file_local_look, selects the formats for
the fit and for the relative white balance. Photo::relative_wb in the
catalog uses the same formats.
- Black level: Nikon stores the black level (maker note 0x003d) in
14-bit units, also in 12-bit files. The decoder read it as a 12-bit
value. Because of this, 12-bit files from the D750, D780, D850, D7500
and Z 50 were too dark. Now the decoder divides the value by 4 for
12-bit files.
- The corpus gets the D7500 12-bit and 14-bit lossless samples. A test
compares their levels. The render cache version increases to 9.
Results on 13 NEF files that LightCraft can decode: LightCraft accepted
the fit for all 13 files. The mean colour difference from the camera
JPEG (CIE76 dE) decreased from 13-46 to 2.9-7.8. One file with mixed
light improved by a small quantity only (12.7 to 12.0).

Sony bodies from before ~2017 (RX100–RX100M5, RX10, NEX, SLT, ILCE-6000,
A7/A7II/A7RII, ...) write no plain 0x7313/0x7310/0x74c7 tags in the raw IFD,
so the decoder used unit WB multipliers (strong green cast, e.g. the CC0
DSC-RX100M3 sample), black 512 (800 on 1-inch sensors), and kept padding
columns at the right edge.
- White balance: WB_RGBLevels from the maker note's enciphered Tag2010
block (layouts per ExifTool's Tag2010a..i tables; byte substitution
p^3 mod 249 checked black-box on 15 CC0 files: SonyISO matches Exif ISO,
ILCE-7M3 levels match its plain 0x7313).
- Black level: recovered from the encrypted SR2SubIFD by known-plaintext
analysis (constant key in every file; RX100M6/ILCE-7M3 plain 0x7310 as
plaintext; 8 keystream bytes at offset 2510, plausibility-checked).
- Crop: DNG DefaultCrop or the maker note's FullImageSize.
- "12-bit uncompressed" ARWs hold 14-bit-scale data: black/white follow it.
- Render cache version bumped; corpus manifest + corpus test, unit tests.

The Japanese fonts (BIZ UDPGothic Regular/Bold for the UI, BIZ UDMincho for text
watermarks; #110, #114) now come from storytold/craft-fonts instead of assets/fonts/.
- crates/engine/build.rs: the craft-fonts recipe. With CRAFT_FONTS_DIR set it embeds
the manifest's fonts as lightcraft_engine::CRAFT_FONTS (wasm32: BIZ UDPGothic Regular
only, for the web size budget); unset, CRAFT_FONTS is empty. Local files only, no
network; craft-fonts is not in any Cargo.toml.
- UI: theme::font_definitions adds the Japanese faces after Inter and egui's defaults
in every family (BIZ UDPGothic first, Bold first for semibold). About box lists the
embedded families.
- Watermarks: Inter, then the craft-fonts Japanese faces (Mincho first).
- Removed BIZUDPGothic-Regular/Bold.ttf, BIZUDMincho-Regular.ttf and their OFL files,
and their ATTRIBUTION rows; added an attribution row for craft-fonts as an optional
build input; NOTICE updated.
- Tests: Japanese glyph tests use CRAFT_FONTS and skip without it; new tests for
Japanese in the UI with craft-fonts and for the UI and watermarks without it.
- CI: the FreeBSD job builds/tests with craft-fonts. Releases check out craft-fonts at
a pinned commit, build with CRAFT_FONTS_DIR + CRAFT_FONTS_REQUIRED=1, and ship the
fonts' OFL licences (plus NOTICE) in every package.
- Docs: AGENTS.md, CLAUDE.md, README, docs/web.md, docs/localization-ja.md, ROADMAP,
parity.

Remove scripts/package-japanese-macos.py, the japanese-local feature and its
config/library/startup overrides, the settings.language migration, and the
local-build notes in the docs. Upstream library and config defaults (incl.
library::default_dir, which already honours LIGHTCRAFT_LIBRARY) are unchanged.

Shippori Mincho's name table credits 'FONTDASU / Google Inc. / but / Adobe' — its kanji
come from Adobe's Source Han Serif, which our asset rules exclude even under the OFL
(CLAUDE.md: no Source Han fonts). BIZ UDMincho (Morisawa Inc., design TypeBank Co., Ltd.;
OFL-1.1, from google/fonts at 63833b7) is a Mincho of its own with no Adobe glyphs, and
smaller (6.2 MB vs 8.7 MB). Attribution, licence text and NOTICE updated.

ROADMAP.md: new 'Where we stand' (by dimension and by kind of user; checklist 79% vs
~60-70% as a day-to-day Lightroom replacement) and 'Where we're going' (ordered priorities:
camera colour calibration, CR3 and compressed raws, verified camera coverage, render fidelity
suite, lens profiles, AI model strategy, then HDR / Classic modules / video). Current
parity numbers, M11 status, risks (raw-source decision of 2026-10-05), log.
docs/parity.md: new rows LR-PROF-CAMERACOLOR, LR-IMP-CAMERA-COVERAGE (P0) and
LR-BEHAV-RENDER-FIDELITY (P1) so quality gaps are tracked; Top gaps reordered by user impact.
README.md: honest status summary above the feature table; stale rows fixed (compressed NEF,
DNG/original export, image watermark, Move import), camera colour and AI/HDR/video rows.
AGENTS.md / CLAUDE.md: agents read the assessment before picking work, and downgrade
✅ rows they find wrong or incomplete.

Decode Nikon Huffman-compressed NEF (compression 34713): lossless and lossy
(type 1 and 2) at 12 and 14 bits, with the maker-note 0x96 linearization
curve, predictor seeds and either byte order. Clean-room: 0x96 layout and
encoding-table sizes from prose write-ups (Clevy, Claff); the fixed Huffman
tables were recovered by black-box analysis of CC0 raw.pixls.us samples
(compressed vs uncompressed shots of the same scene) and verified on ~45
files from ~35 bodies. Lossy-after-split files stay preview only.

- `cargo xtask parity` adds a weighted-completion line (✅ 1, 🟡 ½, out of scope left out) per
tier to the generated summary: 65.7% of 500 in-scope rows (P0 98.5%, P1 79.9%, P2 11.7%).
- ROADMAP: remaining work by package in agent-hours (≈ 295–540; ≈ 75–130 h wall clock with
4–6 agents), effort-weighted completion ≈ 20–30% for full parity, milestone statuses
refreshed, Totals replaced.

- embedded_preview: CR3 PRVW/THMB boxes (plus RAF, RW2, ORF, PEF from the
format commits); stops at the first valid box of each kind
- engine: raw variants that report Unsupported are probed and shown from
their embedded JPEG (orientation from the JPEG or the raw), not an error
- crates/raw/tests/corpus.rs: every corpus/raw file is recognised, has a
JPEG preview (DNG optional) and decodes or is a known-unsupported
variant; prints decode timings
- xtask corpus --download: 37 CC0 raw.pixls.us samples (matched by SHA-256)
- ROADMAP/crate docs: format coverage, NEF Huffman / RW2 format 4 /
compressed ORF+RAF gaps, neutral colour-matrix fallback
