crates/mcp (lightcraft-mcp, L5): hand-written MCP over stdio (JSON-RPC 2.0,
protocol 2025-06-18 with 2025-03-26/2024-11-05 negotiation): initialize,
ping, tools/list, tools/call, resources/list/read. Two backends behind one
trait: Headless (in-process engine Session; answers engine.execute,
engine.commands, ui.render, app.export) and Remote (the desktop app's
loopback JSON-lines control channel; lazy connect + reconnect).
Tools: helpers (list_commands, run_command, import, query_photos,
select_photos, list_controls, get/set_develop, apply_preset, crop,
render_photo -> image content, export), UI tools when connected
(screenshot -> image content, inspect_ui, set_ui, list_widgets, click,
press_key, type_text, pointer_gesture), plus one cmd_<id> tool generated
per command in the registry (--compact omits them).
apps/lightcraft-cli: `mcp [--connect [ADDR]] [--demo] [--compact] [FILES]`,
`render <in> -o <out> [--set control=value]... [--settings] [--preset]
[--size] [--quality]`, `commands`, `controls`.
Acceptance e2e: crates/mcp/tests/e2e.rs sets exposure over MCP and renders
(headless and through the TCP transport); apps/lightcraft-cli/tests/cli.rs
does the same through the real binary's stdio. Docs: docs/mcp.md,
docs/control-protocol.md. Also rustfmt of one line in pipeline/finish.rs
(main was not fmt-clean).

16-bit word and 12-bit MSB-packed uncompressed NEF, maker-note black
levels and WB_RBLevels, masked trailing column trim, robust white
estimate ignoring 0xFFFF padding. Huffman-compressed NEF is reported as
unsupported (no clean-room description available).

Property tests (random bytes behind every magic, mutated/truncated files),
corpus tests (corpus/images, pngsuite, raw routing, system ICC profiles),
ignored 24 MP JPEG benchmark, decode_thumbnail_with(min_embedded_edge),
fast deflate levels for PNG/TIFF, README with formats, licences, gaps.

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.

IFD#3 lossless JPEG with 0xc640 slice reassembly, SensorInfo borders,
masked-column black levels per CFA position, saturation-plateau white,
as-shot WB from ColorBalance. Verified bit-identical to Adobe's DNG of
the same 5D Mark III frame. sRAW/mRAW reported as unsupported.

Decoders (JPEG via zune-jpeg + jpeg-decoder for DCT scaling/CMYK, PNG,
TIFF, WebP, GIF, BMP, PSD composite, JPEG XL via jxl-oxide) produce linear
Rgb32f in source primaries with SourceSpace; ICC matrix/TRC applied exactly,
LUT/CMYK profiles through moxcms; to_working() to linear Rec.2020 D65.
Encoders: JPEG, PNG 8/16, TIFF 8/16/32f, lossless WebP, AVIF (native).

Classic + BigTIFF, both byte orders, all field types, SubIFDs and Exif/GPS/
Interop pointer IFDs, strips/tiles layout, maker-note offset-base helpers,
IFD writer; hardened against malformed input (proptests). Placeholder
manifests for lightcraft-meta and lightcraft-raw.
