`ExportOptions::from_json` reads what it recognises and defaults the rest, so
`longEdgee=400` exported at 3000 px, `longEdge=banana` at full size, and a
`watermark` of `5` or `{"text":"x","bogus":1}` passed with `ok:true`, while
`size: 3` was silently clamped to 0.5 of the short edge (#181, #183).
`from_json` stays lenient for stored prefs and dialog prefill. New
`ExportOptions::validate(cmd, params)` / `from_params(params)` check every key
against the option and target lists (unknown ones name the nearest known key),
every value's kind and range, and a `watermark` object's keys, kinds and ranges
(`size` 0.005..0.5 and `inset` 0..0.4 of the short edge, `imageWidth` 0.01..1 of
the width, `opacity` 0..1, `color` [r,g,b]), returning
`invalid parameters for \`app.export\`: …` like the other commands. The three
places that run an export use it — the desktop `app.export`, the headless
backend behind `lightcraft-cli run` and the MCP `export` tool, and
`lightcraft-cli render --opt` — and `export.savePreset` validates a preset's
params when it is saved. Built-in presets, the Export dialog's `to_json`,
Export with Previous and `render --opt` all pass unchanged.
The `app.export` param string (`lightcraft-cli commands`, `engine.commands`),
the MCP `export` tool schema and docs/parity.md LR-EXP-WATERMARK now list the
watermark keys, their units and ranges.

`select_photos {"ids": [9999]}` answered `selected: 1` and left the session
with no usable active photo; `develop.get {"id": 9999}` answered too.
`library.select` now checks every id (and `active`) against the catalog
before touching the selection and returns `no such photo N`, so the
previous selection and active photo stay in place; `photo_arg` (develop.get,
photo.inspect, photo.allMetadata, history.list) does the same for an
explicit `id`. Engine and MCP tests cover every select mode.
Fixes#182

Skip unchanged thumbnail jobs and reuse bounded settings hashes (both maps
capped at 1024 entries). Reject stale render results and cache writes after
edits, library changes and preview clears: render requests carry a request
id and cache generation, PreviewCache writes and reads hold the generation
lock that clear() takes, and library.clearPreviews also drops cached
sources. The web worker index follows the same generation rule.
The decoder guards, Windows path fixes and test fixture changes that were
bundled in a327b98 are separate commits; the benchmark follows this one.

Switching to Random from another key (without an explicit seed) derives a new seed
instead of reusing the one left behind, which was the fixed seed-0 order on a new library.
Re-choosing Random or changing only the direction keeps the shuffle on screen.
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
- library.shuffle treats a null seed as none given
- seeds are limited to 0..2^53-1 so JSON-double clients read them back exactly
- album test now fails if manual order overrides Random; persistence test goes through
close/reopen of the library instead of a serde round trip
- README lists random among the sort options
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
SortKey::Random orders photos by a splitmix64 rank of (Sort.seed, id): same seed gives
the same order, and added/edited photos never reshuffle the others. library.sort takes
an optional seed; library.shuffle picks a new one (below 2^53 for JSON clients). Menus
gain Random and Reshuffle; Ascending/Descending are disabled for Random. No effect in
Recently Added (always newest import first).

Engine (crates/engine/src/segment/):
- One worker thread owns the model and the encoded photo; the session
sends jobs (with the render job for the model input) and gets results
over channels, never locking what the model holds. In the app
(Segmenter::background) clicks, descriptions, prepares and detail
passes return at once and Session::segment_poll applies results (one
undo step per settled selection, pending clicks shown on the photo);
the CLI/MCP wait for them. Newer requests for the same selection
supersede queued ones.
- Every job runs under catch_unwind: a candle panic becomes an error and
the model is reloaded next time; busy counters are reset by drop
guards; a dead worker is restarted. The model unloads after 10 min idle.
- segment.model.status / .download {acknowledged: true} / .cancel: the
download runs on its own thread; status via atomics (try_lock only).
Without the model every AI request fails at once with "The SAM 3 model
is not installed…"; renders/exports never need it; `seg` params make
AI masks from stored segmentations without it.
- Hostile documents: at most 4 detail patches per component (capped on
deserialize and in the renderer), at most 64 Object clicks.
UI: Object / Describe without the model open "Download the SAM 3
Model?" (size, folder, SAM License link; Not Now / Download, progress,
cancel, Try Again with the reason, Continue once installed); progress in
the Masking panel when the dialog is closed. Reverted the PR's unrelated
default change (mask overlay off + hover-red) to main's behaviour.
tools/install-sam3.*: --fail so error pages never land in files, 416

photo.reload had no menu path, so the documented way to refresh CR3s imported
before their metadata was read (Photo > Reload from Disk) did not exist in the
app. It is now in the Photo menu and the photo context menu, and besides
size/preview-only it fills camera fields the catalog lacks (camera, lens,
exposure, GPS, capture time) from a fresh probe, never overwriting a set value.
Photos in Recently Deleted could not be restored from the app: photo.restore and
photo.deletePermanently existed only as engine commands, and adding the same file
again just said "1 duplicate skipped" (the duplicate check counts deleted photos),
with the side panel that lists Recently Deleted collapsed by default.
- Restore and Delete Permanently in the Photo menu and the photo context menu,
in place of Delete, when the selection is in Recently Deleted.
- The filmstrip gets the photo context menu (it had none).
- An import that only finds files the library already has selects those photos:
in Recently Deleted (side panel opened, how to restore or delete permanently and
import afresh) or in All Photos. Mixed imports note how many are in Recently
Deleted. The message stays 6 s.
- Import review badges say "In Recently Deleted"; badges are translated.
- Japanese strings, parity rows, what's new; headless regression test.
Hovering a box shows handles at its corners and edge midpoints; dragging one
previews the new box live and commits once on release, as one undo step, through
the new `photo.setRegion {id?, index, rect}`: catalog-only like removal, never
rewriting the sidecar, with the rectangle validated (finite numbers only,
clamped to the photo, at least 0.5 % each way) and a test with a real sidecar.

View > Face Boxes (and a toolbar button in the loupe) hides or shows the boxes.
Hovering a box shows a × in its corner; clicking it runs the new undoable
`photo.removeRegion {id?, index}`, a catalog-only edit. The XMP sidecar is
never rewritten for it, even with auto-write on (a `skip_auto_write` flag
consumed when the command ends), because the sidecar writer builds a fresh
packet that does not carry the regions: reading the metadata from the file
brings a removed region back. A test with a real sidecar proves the file stays
byte for byte, that ordinary edits still auto-write, and that undo restores it.
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
Read-only and names-only: the left panel gets a People section built from the
named Face regions read from XMP, with photo counts (once per photo, case
insensitive, pets and unnamed faces left out). A click filters the grid via a
new `person` field on `library.filter`, also reachable as a `person:` search
token and shown as a filter chip. The list is cached on the catalog revision.
No face detection, identity or writing regions back yet. Parity rows for the
People list, filter and view are 🟡 with that scope noted.

AI masks from Meta's SAM 3, run in LightCraft itself: a new
`lightcraft-segment` crate ports the Hugging Face transformers
implementation (Apache-2.0) to candle, on the GPU through Metal on macOS
(CPU elsewhere), with no C/C++ and no `unsafe`.
- Object: click to include, ⌥-click to leave a part out (SAM 3's
interactive prompt encoder + two-way mask decoder).
- Describe: a text prompt selects every instance ("sky", "the red car";
"car, road" merges several) via the CLIP text encoder and DETR detector.
- Both as new masks and as Add / Subtract / Intersect components; + / −
buttons under the selected mask combine selections.
- The segmentation is stored with the mask (288² quantized logits, ~10-30
KB), so renders, exports and the web build never need the model.
- A zoomed-in detail pass (background, ~5 s on an M4 Pro) re-segments the
area around a selection from a sharper source: 5-10x finer edges on
small objects.
- Per-selection Edge slider (hard ↔ soft); hovering a mask in the list
shows it in red (the always-on overlay is now off by default, O toggles).
- The engine feature `sam` (on in the desktop app) gates the model; the
image is encoded once per photo in the background, clicks take ~35 ms.
- Weights are not bundled (SAM License): tools/install-sam3.sh / .ps1
download and verify facebook/sam3; docs/ai-masks.md.
- Clearer errors (missing file, missing model) and a stderr logger in the
app (LIGHTCRAFT_LOG=info).
candle is pinned at 0.9.2: later releases make candle-core depend on
tokenizers with the Oniguruma C library. Every stage is checked against
the Python reference (tests/reference.rs, tools/sam3_reference.py): on
Metal the backbone matches to 7e-5 relative error, masks to ~5e-5.

- safe_file: write policy documented (durable for what can't be recreated, atomic-only for
recreatable outputs); new write_atomic_nosync (temp + rename, temp removed on failure, no
file/folder sync); per-thread sync counter for tests.
- export::write_file (exports, renders, screenshots, merge previews, CLI/MCP) uses the
non-syncing writer; new write_file_durable keeps the sync for Edit a Copy (the TIFF becomes a
library photo). Catalog, sidecars, settings, DNG conversion/merges and smart previews stay
durable; the #93 original-overwrite guard is untouched.
- Import > Copy verifies the synced copy against the probe's content hash (SipHash-1-3/128 of the
whole file) instead of re-reading the source; byte compare when there is no hash. A file changed
since Review Import is now refused instead of imported with stale details. Move keeps its
byte-for-byte check before deleting sources.
- check_write_target: skip building the library-wide guard when nothing is at the target.
- write_new_unique keeps its read-back (DNGs replace raws; cheap next to encoding).
- Tests: no sync on the export path, durable writers still sync, Copy caught by the probe hash
(corrupt copy, stale hash, changed source); ignored timing test write_policy_timing.

Smart previews store the decoded source with the fitted colour matrix
baked in, but the file-local tone curve lives in the decoder's
SourceInfo, which a proxy did not keep: an offline ARW rendered and
exported with the generic filmic curve instead (darker, a different
look). The proxy header now carries the curve (validated on load,
ignored when invalid), DecodedSource::info_or merges it into the header
facts, and is_valid reads the longer header.

Resolve SourceRef::load_source against #104's offline fallback: a File
source keeps the decoder's SourceInfo; a smart-preview fallback has none.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Re-applies fix/issue-104-ui-fs on top of the data-safety fixes (integrate/safety):
- availability cache: originals and smart previews are checked on a worker thread; the UI
answers from the cache (grid, Info panel, photo menu, Missing Photos view)
- import split into ImportJob::prepare (worker) + commit_prepared, with Cancel; Copy keeps
#96's verified copies
- Find Missing Photos: find_candidates (snapshot, no I/O) + plan_find_missing (all file I/O,
on a worker, never the session) with #105's matching rules unchanged (name+size+hash;
renamed by size+hash; single name+size; ambiguous look-alikes skipped and reported; files
already in use excluded). The plan is applied with library.findMissing {found, missing,
ambiguous}, re-checked against the catalog then: photos relinked meanwhile are left alone,
files now in use are not taken. library.findMissing {folder} still runs synchronously.
- Build / Discard Smart Previews with background: true runs on a worker with progress and
Stop, keeping #106's atomic writes, is_valid checks and `repaired` count (also in
library.previewProgress); the render worker's smart-preview fallback uses is_valid
- Rename preview planned on a worker (plan_rename_photos) on the same planning core as
Session::plan_rename_with (MoveFs, case-only respelling by file identity, #95)
- Local folder listing via fs_cached; tests_offline (slow injected probe, frames < 300 ms)
Tests: worker-planned Find Missing equals the synchronous command for a renamed + ambiguous
library; a plan is re-checked when applied; background smart previews repair a damaged proxy.

- Library settings (prefs.json, presets.json, view.json): only a missing
file means "defaults". A file that doesn't parse is kept as
<name>.corrupt-<unix time> before the defaults are used; one that can't
be read (locked, I/O error) is never written this session (save_prefs
refuses, presets/view saves skip it). Warnings go to library.info →
settingsWarnings and Session::take_library_warnings; the UI shows each
once in a window (ui.inspect → notices, button:noticeOk).
- Desktop ui.json (holds the library location): written atomically (temp +
fsync + rename + dir fsync), saved as soon as the library path changes and
every few seconds when it changed, failures reported; a damaged file is
renamed to ui.json.corrupt-<time> and reported, an unreadable one is not
overwritten.
- Quit/close with changes only in memory: retry the save (log, then a
snapshot of everything), and if it still fails cancel the close and ask:
Try Saving Again / Quit Anyway / Cancel (ui.inspect → quitPrompt).
- Tests: engine (damaged prefs kept, unreadable presets/prefs untouched),
desktop (damaged ui.json kept, atomic write), headless UI (quit prompt
buttons, settings notice).

The folder move and the photos' relinks form one undo step: undo renames
the folder back on disk (files and sidecars along) and restores the
paths, redo repeats it. A destination taken in the meantime is never
overwritten; the step is refused, reported and stays on the stack.

- Convert to DNG / Copy as DNG: the encoded DNG must decode to the same raw
data, then goes through safe_file::write_new_unique (temp file, sync,
read-back, hard-linked to the first free <stem>.dng / -2 / -3 name, never
replacing a file). On failure no DNG is left, the photo is not relinked
and the raw copy is kept.
- Photo Merge writes its DNG the same way.
- Smart previews are written atomically; smart::is_valid (header + complete
JPEG) decides "built", has_smart_preview and the offline fallback, so a
proxy cut short is rebuilt (reported as `repaired`); moving proxies to a
new folder never deletes a good one in favour of a damaged copy and
copies across drives atomically.
Stacked on the #93 branch (shared lightcraft_catalog::safe_file helper).
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Saving (Cmd+S or auto-write) now merges LightCraft's properties into an
existing sidecar (lightcraft_meta::merge_xmp): owned properties (rating,
label, dc/IPTC/rights fields, lc:*) are replaced or removed, capture time
and GPS only when LightCraft has a value; everything else (crs:,
xmpMM:History, unknown namespaces, packet wrapper) is kept byte for byte.
The result is re-parsed and checked before it is written (temp + fsync +
rename). A sidecar that isn't valid XMP is copied to .xmp.bak-<time>
(never overwriting) before it is replaced; one that can't be read at all
is left alone and the save fails.
Shared stems: when several catalogued files map to one stem sidecar
(IMG.CR3 + IMG.JPG), it belongs to the raw (else the first by name) and
the others write and read <file>.xmp.

- lightcraft_catalog::safe_file: one tested helper for crash-safe writes
(temp file in the same folder, sync, rename, folder sync; temp removed on
failure), write_new/write_new_unique that never replace a file and read
the result back, same_file, and a per-thread fault injection for tests.
- engine::originals::OriginalGuard: refuses a write whose target is a
catalogued photo's original or XMP sidecar (by file identity), whatever
the conflict policy or exact path. Used by run_batch (export, Export with
Previous, control/MCP exact paths), ui.render/ui.screenshot paths, merge
previewPath, MCP render_photo/screenshot paths (new query command
export.checkTarget) and lightcraft-cli render.
- The conflict policy now covers an export's sidecars together with the
file (Unique gives both the same free name, Skip skips when either is
taken).
- export::write_file replaces the plain std::fs::write in the desktop app,
CLI, MCP and engine writers; XMP sidecar writes use the shared helper.

Rollbacks in move_file, apply_rename and undo/redo no longer ignore
errors: every move that can't be undone is reported (old -> new), and the
catalog follows the files that kept their new names (an undoable partial
rename; a logged change for undo/redo), so nothing shows as missing.
A file that can't go back keeps the sidecars that moved with it.
library.findMissing: same name + size confirmed by the stored content
hash first, then renamed files by size + content hash, then a unique
name + size match; several look-alikes are skipped and reported in
'ambiguous' instead of guessed. Files already used by a photo are skipped.
Stacked on fix/issue-95-case-only-rename (same functions).

A GPU render no longer hands back an image it cannot vouch for:
- set the wgpu device-lost callback (wgpu never reports a lost device as an
error, so a driver reset went unnoticed); readback waits with a timeout and
checks the poll result and map callback instead of blocking forever
- each render runs in OutOfMemory/Validation/Internal error scopes; errors
fail that render (OOM and limit failures for that render only, device
errors for the process) and it is redone on the CPU
- every buffer is checked against the device limit when created (no
validation error, no process-wide disable); LIGHTCRAFT_GPU_LIMITS=webgpu|<MiB>
creates the device with lower limits to reproduce small adapters
- the output buffer is cleared and the per-pixel kernel writes alpha 255:
any unwritten pixel (work silently dropped, the issue's all-black export)
fails the render; an all-black result is re-rendered on the CPU
- renders submit per stage and every 16 M invocations, the per-pixel stage
runs in ~4 MP bands: no long submission for a slow iGPU's watchdog to reset
- ui.inspect perf.gpuReason / perf.gpuFallback, app.gpu reason/lastFallback,
System Info and Settings say why the GPU is off (e.g. llvmpipe skipped) and
why the last render fell back
Tests: crates/gpu/tests/fallback.rs (limit, mid-render limit, validation
error, dropped work, black photo), engine export falls back to the CPU image,
banded 3000x2000 GPU/CPU equivalence.

Local browse records can be most of a large catalog (85k photos, 90 %
Local: 313.5 MB snapshot). Untouched Local records of folders whose last
browse is older than library.preferences forgetLocalDays (default 30,
0 = never) are now removed from the catalog when the library opens (and by
library.forgetLocal {dryRun?, days?}), as journaled, non-undoable ops, then
compacted in the background. Files and XMP sidecars are never touched;
browsing the folder again catalogues them afresh.
Untouched = a Local file record, not deleted, not a virtual copy, whose
state still hashes to the fingerprint taken when the browse catalogued it
(any change keeps it); records from before fingerprints need every
user-editable field empty/default. Kept too: records in albums (or as
cover), stacks, sources of virtual copies, visible/selected/edited ones,
ones referenced by undo/redo, ones with a smart preview.
Per-folder last-browsed times live in the catalog (Op::SetBrowsed,
normalised with folder_key; re-stamped at most hourly). Old catalogs load
unchanged; folders without a time are stamped now, so nothing is forgotten
on the first open after the upgrade.
persist_bench (85k photos, 76.5k Local, every 7th folder recent, 1 in 50
rated): 63.8k forgotten, plan 162 ms, snapshot 313.5 MB -> 94.9 MB.

A command whose journal append fails now returns EngineError::NotSaved
("saved in memory but not written to disk: <reason>; LightCraft will retry")
instead of OK. The change stays applied and undoable, its ops stay queued and
are written by the next save (any command, or the frame loop with a 2 s
backoff). Queries and commands that change nothing are unaffected; a failed
compaction is reported in lastError, not as a failed command (and a failed
synchronous snapshot now backs off like a background one).
Session::unsaved(), library.info unsavedOps/unsavedError, ui.inspect unsaved;
the desktop UI toasts the failure and shows a warning on the top bar's cloud
icon until a save succeeds.

library.import mode `move` (UI: Transfer ▸ Move, MCP import tool): reuses
Copy's destination, folder organisation (incl. custom templates) and rename
template. Each photo and its XMP sidecars (both namings) are placed without
touching the source (hard link on the same volume, else a new file that is
copied, synced and compared byte for byte; taken names get -1, -2…, never
overwritten). Sources are removed only after the catalog records are
committed and saved, and only when the destination is still intact; failed,
duplicate, unchecked and in-library files keep their sources; sources that
can't be removed are kept and reported (`kept`). Undo removes the catalog
records and leaves the moved files at the destination.
