- 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).

menubar.rs builds File/Edit/View/Photo/Window/Help from engine + UI
commands (layout table for order and separators, parameterized submenus
for rating, flag, label, sort, add to album), with live labels ("Undo
Exposure"), enabled and checked state; ui.menu.tree exposes it. The
desktop app installs it natively on macOS with muda (pure Rust over
AppKit; no GTK — muda is a macOS-only dependency): app menu (About,
Services, Hide, Quit), Window menu (Minimize/Zoom/Bring All to Front),
Help menu; per-frame state sync; accelerators without Cmd and the text
editing ones step aside while a text field has focus; natively handled
shortcuts are skipped by the egui handler. Other hosts (web, Windows,
Linux) get the same menus in the top bar. Panels/sections/tools move to
the Window menu. Verified with System Events: menus listed with live
enabled state, View > Survey dispatches.

- 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).
