- 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

16-bit LE words (12-bit-in-top-bits detected and shifted), 12-bit rows
of LE 32-bit words read MSB-first (black-box), maker-note
ImageProcessing crop, BlackLevel2, WB_RBLevels for old- and new-style
notes, CFA phase from the data (GRBG/RGGB), CameraSettings preview.
Compressed ORF reports Unsupported (documented gap).

Huffman table from maker note 0x0220 (codes/lengths, black-box layout),
T.81 difference categories, same-colour horizontal prediction with
per-row-parity vertical seeds; BlackPoint, WB levels, maker-note image
area or dark-column trimming. Unit round-trip test with our own table.

Black-box derived layout: 0x4000-byte chunks stored rotated by 0x1ff8,
16-byte LE blocks read LSB-first (10x12-bit or 9x14-bit samples).
Sensor borders, CFA code, per-channel black, linearity limit, WB levels,
ISO; JpgFromRaw preview via a generic undefined-tag JPEG candidate.
The quantised raw format 4 reports Unsupported (documented gap).
Adds a rawdump debug example.

- engine::import: expand files/folders recursively (sorted; hidden entries
and the library folder skipped), skip known paths, probe + hash in
parallel (std:🧵:scope), skip duplicates by content hash (against
the library and within the batch), add in place or copy into
<library>/Originals/YYYY/YYYY-MM-DD/ with unique names; one undoable op.
- library.import {paths, mode: add|copy, album?} returns
{imported, duplicates[{path, existing, reason}], failed, scanned}.
- probe_bytes records the content hash (SipHash-1-3 128) on every photo.
- system clock for import/edit times on native (Session::with_system_clock).
- app: command-line folders are expanded by the engine (re-importing the
same folder is a no-op); example gen_photos writes procedural test JPEGs
(never committed).
- Measured (200 procedural 2000 px JPEGs, M-series): import 2.25 s; reopen:
library load 1.7 ms, control ready 0.12 s, first thumbnail 0.17 s,
visible grid drawn 0.48 s (thumbnails from the disk cache).

apps/lightcraft-web runs the egui UI in the browser (eframe web, glow/WebGL2):
procedural demo library on load; in-memory imports via file picker
(Cmd+Shift+I) and drag-and-drop (MemStore + bytes-based engine hooks);
export goes through app.export and downloads in the browser; `?bench` logs
first-frame and slider latency. `cargo xtask web [--serve [port]] [--dev]`
builds with the matching wasm-bindgen CLI into <target>/web/; the web app is
part of the CI wasm check. Wasm fixes: lazy profiling Instant in pipeline,
web-time clocks in ui-egui (render timings were 0 on wasm). Docs: docs/web.md.
No persistence on web yet.

3–10x faster blurs on a 3000x2400 plane (min-of-9; machine under load, see blur_bench example).
LIGHTCRAFT_PROFILE=1 now also times log-lum, base, clarity, texture, dehaze, masks and NR.

- new crate lightcraft-preview (L3): 128-bit content hashing (SipHash-1-3),
cost-bounded Lru, DiskCache (JPEG q90 files keyed by content hash +
settings hash + size + RENDER_CACHE_VERSION; temp+rename writes; LRU prune
by mtime to 80% of budget; corrupt files dropped), PreviewCache (memory
LRU over disk), JobPool (per-slot dedupe, priorities, reprioritize/drop,
inline mode for wasm).
- engine: Session::thumb_job buckets thumbnails to 128/256/384/512 and serves
them from the cache without decoding the source; decoded thumbnail
sources now in a 384 MB LRU (was unbounded); library attaches
<library>/thumbs; library.info cache stats; library.clearPreviews.
- ui-egui: Renderer runs on JobPool; thumbnails scrolled out of the
prefetch area are dropped from the queue; on-screen thumbnails get
re-prioritized; ui.inspect reports in-flight renders + thumb textures.
- Demo library (24 photos): grid fully drawn 4.4 s cold -> 0.21 s warm
(24/24 disk hits, no source decoded).

RAF header/record parsing, raw IFD (0xf000) with 16-bit, 12-bit LSB and
32-bit-word MSB packings found by black-box analysis of CC0 samples,
X-Trans layout (reversed record, anchored at 0,0), crop, black levels,
WB_GRB levels, metadata and preview from the embedded JPEG. Compressed
RAF reports Unsupported. Colour uses the documented neutral fallback.

- catalog: Store trait (FsStore: temp+fsync+rename+dir fsync; MemStore),
Journal: CRC-checked JSON-lines op log with sequence numbers + atomic
snapshots; torn final record dropped and truncated, stale records after a
snapshot skipped, mid-log damage preserved as catalog.log.damaged-N.
- PushHistory op so each edit logs one history step (not the full history).
- engine: Session::open_library/persist/close_library; every top-level
command is fsynced before returning; presets.json + view.json;
library.info / library.compact commands.
- app: default library ~/Pictures/LightCraft Library (LIGHTCRAFT_LIBRARY or
--library DIR override), --memory for throwaway sessions, snapshot on quit.
- tests: proptest replay(log)==state with random snapshots/reopens, every
truncation of the last record, stale log, mid-log damage, FsStore, engine
restart without close.

Export encoding lives in lightcraft-engine::export (pure bytes, shared by app/CLI/MCP/web).
Embeds our own sRGB ICC; writer creates the output folder.

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.
