library.devices lists mounted volumes with a DCIM folder (macOS /Volumes, Linux /media and
/run/media, Windows drive letters; LIGHTCRAFT_DEVICE_ROOTS overrides; cached for 2 s).
File → Add from Device opens the import review of a card's DCIM folder, set to copy into the
library.

- Engine: export split into prepare_export (session thread, cheap) and PreparedExport::run
(Send: read/decode/render/encode); run_batch with per-photo progress, cancel and collected
errors; export_batch keeps the stop-at-first-error behaviour for scripted calls.
- Desktop: the Export dialog, Export with Preset (menu and context menu) and Export with
Previous run their batch on a worker thread (app.export {background: true}); a progress
panel shows count / file / Cancel; ui.inspect reports export {running, last}.
- Headless: settle waits for a running export; `lightcraft-cli snapshot` finishes it before
exiting. Web keeps foreground exports (downloads are main-thread).

`lightcraft-cli run [--demo | --library DIR | --connect [ADDR]] [--import PATH]… CMD k=v … CMD …`
runs any engine/UI command or control-protocol method (headless, on a persistent library, or
against the running app) and prints one JSON line per command; non-zero exit on failure,
--keep-going, --script FILE|- for JSON lines. Imported photos are selected (first active) so
the chain acts on them; a library's edits are saved for later invocations. Docs: docs/mcp.md,
README.

- Resize modes: long edge, short edge, width, height, W x H (either orientation), megapixels,
percent; "don't enlarge" (default on); ppi written to JFIF density / PNG pHYs / TIFF tags.
- Full-size export of a cropped photo now renders the crop at native resolution (it was
upscaled to the uncropped long edge).
- Formats: Original (file copied byte for byte + XMP sidecar with the edits, named after the
output) and DNG (raw photos re-encoded losslessly, edits in the embedded XMP).
- Export dialog: Resize-to dropdown, values, Don't enlarge, Resolution; DNG/Original hide
pixel options.
- lightcraft-cli render goes through the shared exporter (colour space, metadata, ppi) and
takes any app.export option via --opt KEY=VALUE; MCP export schema lists the new params.
- xtask resolves the workspace root at run time (a moved checkout broke ci).

- memory::budget (default min(25% RAM, 1.5 GiB); LIGHTCRAFT_MEMORY_MB, app.memoryBudget):
half for engine caches (sources + rendered previews, LRU across them via a global
use tick; the photo on screen stays), a quarter for decodes in flight (WorkGate:
thumbnails, prefetch and import probes wait; loupe/export loads never wait), an
eighth for the GPU free pool.
- GPU: best-fit buffer reuse (<= 25% slack), buffers released outside a render are
pooled at once (no stranded retired lists), pool trimmed after 3 s idle.
- Decodes drop file bytes and raw samples early, colour/crop/orient in place.
- macOS: apps install malloc_zone_pressure_relief as the release hook (after each
decode, import and idle trim): freed large blocks no longer stay resident.
14 raws + loupe + 12 steps (M4 Pro): peak RSS 1.9-2.3 GB -> 0.83-0.99 GB, footprint
2.5-2.6 GB -> 0.91-0.96 GB, heap peak 930 -> 656 MB; stepping median ~13 ms.

Decoders take a Mode: Header reads everything but the samples (DNG, CR2, ARW,
RAF, RW2; PEF when it has crop tags). NEF/ORF (and PEF without crop tags)
derive geometry/CFA from the samples and still unpack them. decode() stays
bit-exact (debug-hash of every corpus/raw decode identical before/after); the
corpus test asserts probe_info == decode().info() for all 37 files.
Import of 14 corpus raws: 3.4 s -> 1.4-2.0 s; peak RSS through import
1.41-1.49 GB -> 1.12-1.22 GB.

- engine: `merge.hdr`, `merge.panorama`, `merge.hdrPanorama` (bracket size from
EXIF); MergeJob (Send) with progress/cancel, preview renders through the develop
pipeline (deghost overlay, auto-crop frame); finish writes <name>-HDR/-Pano.dng
next to the first source, imports, selects, applies Auto Settings / auto crop
- ui: Photo Merge dialog (HDR / Panorama / HDR Panorama) with live preview on a
worker thread, background final merge with progress toast; context menu and
Ctrl+H / Ctrl+M (Ctrl now means the physical Control key on macOS)
- cli: `merge hdr|panorama|hdr-panorama`, `synth-merge` for synthetic inputs
- merge::synth: procedural brackets (DNG) and panorama views; docs/merge.md

- ui-egui/softpaint: pure-Rust rasterizer for tessellated egui output (gamma-space premultiplied
blending like egui-wgpu, bilinear texel-centre sampling, scissor clips, tie-break rule so shared
edges blend once, parallel row bands, deterministic) + CPU texture mirror from TexturesDelta.
- ui-egui/headless: HeadlessView (offscreen context with our fonts/theme) and Headless (windowless
app session: logic+ui per frame, answers viewport Screenshot/InnerSize/Close, settle loop,
control requests through the shared handler).
- ui.screenshot {headless: true} in the running app renders from the logic tick (works while the
window is occluded / display asleep); windowed captures fall back to headless after 2 s.
Screenshots now wait for in-flight renders, not just queued ones.
- lightcraft-cli snapshot [--demo|--library DIR] [--script f.jsonl] -o out.png --size WxH --scale S.
- Fixes found with it: dialog backdrop was painted over the dialog itself (now an area below the
window); dialog content padding; crop overlay options use our buttons (registered widget ids).
- Docs: control-protocol.md (headless section), AGENTS.md (prefer headless when unattended).

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).
