Brandon ThomasandClaude Opus 5.5 345f0454f2 M3.7: Sony ARW decoding (ARW2 cRAW, uncompressed, LJ92 tiles)

ARW2 implemented from Dietz, EI 2016 (128-bit blocks, interleaved 16-pixel
sets, 7-bit scaled deltas, 5-segment tone curve from 0x7010); black/white/
WB/CFA/crop from the raw IFD's documented Sony tags. Verified visually on
A7 III / A7 IV samples; ~500-850 MP/s row-parallel decode.

LightCraft

A fast, beautiful, open-source photo library and non-destructive raw developer — a clean-room, pure-Rust alternative to Adobe Lightroom. Runs on macOS, Windows, Linux and the web (WASM).

Engine-first Cargo workspace; the egui UI is one swappable crate.
Everything is a command: every menu item, slider, brush stroke and crop drag is drivable over a JSON control channel and an MCP server, so agents can cull, develop and export.
Scene-referred, wide-gamut float pipeline; own RAW decoders; local-first catalog.

cargo run --release -p lightcraft            # desktop app
cargo run --release -p lightcraft -- --control 7980   # with the automation channel
cargo run -p lightcraft-cli -- mcp           # MCP server (stdio)
cargo xtask ci                               # fmt, clippy, tests, layering, wasm
