Andrew FrahnandClaude Opus 5.5 6cbc0eb5a9 Phase 0: configurable brand, MIT licence, plan/ and Immich tracker
- brand.toml is the only place the product name lives; every crate and app
  reads it through dac-brand (env vars with legacy fallback, settings folder
  with copy-only migration, default library, preset extensions, i18n {app})
- cargo xtask brand check|test, run|install|package, docs, rename-crates,
  deny and immich; packaging files are templates rendered from brand.toml
- icons regenerated from brand/icon.svg; upstream branding removed
- MIT licence (segment and fetch stay Apache-2.0); cargo deny licence policy
- clean-room rules in AGENTS.md/CLAUDE.md; docs/upstream-merge.md
- plan/ rebuilt and committed; parity tracker reopens Classic rows, adds
  PLAN.md section 2 rows and the IMM Immich section; plan/immich.md and a
  pinned Immich test server

Andrew FrahnandClaude Opus 5.5 fb097d61be Rename crates to neutral dac-* codename and binaries to app/app-cli
Mechanical rename right after the fork so upstream merges map cleanly.

Exalted5373andClaude Opus 5.5 1ed80c65bf LR-IMP-FORMATS: decode JPEG XL compressed DNG tiles (DNG 1.7)
Compression 52546 tiles and strips decode through jxl-oxide (new
default-on `jxl` feature of lightcraft-raw): bare codestreams and
ISO-BMFF containers, 1 or 3 planes, 8-16-bit integers scaled back
exactly from the codestream's own bit depth, 16-bit floats. Edge tiles
may be coded at their nominal or in-image size. Headers are checked
against the IFD in header-only probing too. A single-chunk JPEG XL
preview IFD (RGB or grey) is offered as the embedded preview.

The decoder's memory is bounded by the tile: 16 bytes per sample (three
times that for a lossy grey tile, which the decoder expands to three
channels) plus 64 KiB; jxl-oxide 0.12 was measured at <= 10.3 bytes per
sample for lossless and <= 13.5 per colour sample for lossy tiles. A
codestream needing more (e.g. extra channels) is an error.

Lossless tiles are checked bit-exact on synthetic CFA and LinearRaw
files (zune-jpegxl as a test-only encoder); lossy tiles are unverified
on a real file.

Brandon ThomasandClaude Opus 5.5 8a3489da6b LR-IMP-FORMATS: decode lossy (DCT JPEG) DNG — Smart Previews and lossy DNG exports
DNG compression 34892: each tile / strip is a baseline JPEG of 8-bit samples (decoded with
zune-jpeg, pure Rust), then the usual linearization table, levels and crop apply. Per the DNG
specification. Lossy DNGs (Smart Previews, "lossy compression" DNG exports, many phone DNGs)
now open as raw files instead of falling back to their embedded preview. Unit test with
synthetic JPEG tiles (edge tile cut short); the corpus sample decodes (5760×3840 in 144 ms).
