Two targeted fixes:
- Tag Cloud atlas SVG radial gradient now switches its inner stop from white
to a warm dark tone (rgba 60 50 30) when the Subtle Light theme is active,
matching the explore-tag hover glow style used elsewhere in light mode.
- Switching the AI Workspace tagging queue scope to "Selected Folders" no
longer auto-selects the first folder in the list; the selection now starts
empty so the user can choose exactly which folders to target.
Replaces the flat TagManageRow list with a virtualized grid of
TagManageTile cards using @tanstack/react-virtual and dynamic measured
heights (46px idle, 82px when editing/confirming). Adds a filter input
and a sort dropdown (most-used / least-used / A-Z / Z-A). renameTag and
deleteTag no longer clear exploreTagEntries on invalidation so the
manager keeps its filter/sort state during the background refresh.
Light-theme overrides cover all new tag-manager class names.
Hovering a tag in Explore now loads and displays co-occurring tags as a
weighted cloud. New `get_related_tags` SQL self-join (db.rs/commands.rs),
`loadRelatedTags` store action with per-folder keyed cache, and TagCloud
atlas UI with ResizeObserver-driven layout and RAF animation. Explore tag
limit raised to 180; tag cloud auto-refreshes 700ms after new AI tagging
completes.
Add a dev-only Vite UI mode with Tauri API mocks, in-memory fixture scenarios, reusable media source handling, and documentation for browser-based visual testing.
Security / robustness / a11y polish on top of the color-search + tooltips work:
- URL opening: route through validated backend commands (open_map_location
with lat/lon bounds-checking, open_changelog_url with a fixed URL) instead
of the frontend opener:allow-open-url capability, which is now removed.
- EXIF GPS parsing: validate coordinate ranges and require the correct
N/S/E/W hemisphere ref byte, then clamp.
- Guard double-submit on album create / add-to-album (Lightbox, BulkActionBar,
Sidebar) and discard stale autocomplete responses in the bulk tag editor.
- Gallery tile: stop nesting <button>s — non-interactive tile div with an
overlay button for open/toggle; checkbox and Similar promoted with z-index
+ focus rings.
- Accessibility: keyboard handlers, focus-visible rings, and aria on album
rows, tag-manage actions, and tile controls; Tooltip uses a block <div>
wrapper in block mode and aria-hidden when hidden.
- Show the destination URL in a tooltip on the "Full changelog" link so the
user can see where it goes before clicking.
- Toolbar "All" filter also clears the color filter; color-filtered views no
longer get unfiltered newly-indexed images injected.
- Sidebar reorder: bail if the album set changed mid-drag.
- Tooling: add cargo fmt scripts; alphabetize package.json scripts.
EXIF info panel:
- New on-demand get_image_exif command (kamadak-exif) returning camera/lens/
aperture/shutter/ISO/focal-length and decimal GPS; read from the file when the
lightbox opens (no DB schema change, works on already-indexed images).
- Lightbox shows a Camera panel; GPS opens the location in the browser via
OpenStreetMap (adds opener:allow-open-url capability).
Tag management:
- Backend rename_tag (rename, or merge when the target exists) and delete_tag
(library-wide), both clearing the tag-cloud cache; store actions invalidate
tag caches, refresh Explore, and re-point/refresh an active tag-search.
- Explore -> Tag Cloud gains a Manage mode: a flat list with per-tag rename/
merge/delete.
Albums:
- Drag-to-reorder in the sidebar via framer-motion Reorder with a hover handle;
order persists through the existing reorder_albums command.
Reads live store order on drag end and robustly derives GPS hemisphere from raw
EXIF ref bytes (review follow-ups). CHANGELOG updated.
Timeline, Explore, and Duplicates get a folder-scope dropdown in their
headers (Timeline via the shared Toolbar), so changing scope no longer
means leaving the feature and bouncing through the sidebar. The new
setViewFolderScope store action updates selectedFolderId while
preserving activeView: Timeline/Gallery reload images, Explore reloads
via its existing selectedFolderId effect, and Duplicates loads the
cached results for the new scope (fresh scans remain an explicit
Rescan). Sidebar behavior is unchanged — clicking a library still
opens its gallery.
Adds a full discovery and organisation layer to the gallery.
## AI Tagger
- WD tagger (ONNX via ort) with DirectML/CPU acceleration
- Per-image and per-folder tag queuing; configurable batch size and
confidence threshold; model downloaded on first use via ureq/zip
- Tags stored with source ('ai' | 'user'); user tags are never
overwritten by AI; AI tags protected from accidental promotion
- Tagger pause/resume per folder; in-flight batches discarded cleanly
on pause or cancellation without leaving jobs stuck in processing
## Semantic & Tag Search
- CLIP text-query embedding via candle (HuggingFace hub model)
- Progressive candidate doubling with filter post-processing so
folder/rating/media-kind filters do not silently under-return results
- Tag search with DB-backed pagination (offset + COUNT total)
- Filename search unchanged; prefix syntax: s:, t:, f: in search bar
## Similarity Search
- HNSW in-memory index (hnsw_rs) with monotonic embedding_revision
counter for cache invalidation; build_index retries if a concurrent
write advances the revision during construction
- Folder-scoped similar search uses brute-force cosine scan (no k limit)
- Region-based similarity: crop an arbitrary rectangle in the lightbox,
embed it with CLIP, find the nearest images globally or within folder
- Pagination for both similar and region results; scope toggle
(all media / current folder) re-runs the query without reopening image
## Duplicate Finder
- Three-phase detection: stat (size) → sample hash (4×16 KB windows)
→ full-file hash (xxh3, large files only) to eliminate false positives
- Filesystem-first deletion: only removes DB rows for files successfully
deleted from disk; failed files remain visible for retry
- Persisted scan cache (SQLite) with invalidation on reindex and deletion;
both global and per-folder scopes invalidated after any deletion
## Tag Cloud & Explore
- Visual cluster explore: k-means over CLIP embeddings, configurable k,
representative thumbnail per cluster; cache keyed on xxh3 of embedding set
- Tag explore: ranked tag list with image counts and representative
thumbnail per tag; invalidated when AI tagging completes or folder removed
- Tag autocomplete for search bar
## Folder Management
- Inline rename (display name only, not OS rename)
- Relocate: file-picker to update folder path; all image paths rewritten
using SUBSTR prefix replacement to avoid corrupting paths that contain
the folder name as a substring
- Missing-folder recovery banner: Locate or Remove, never silent deletion
- Right-click context menu on sidebar items: Reindex, Rename, Locate,
Remove; hover buttons preserved alongside context menu
## Background Tasks
- Per-folder progress panel with embedding, tagging, caption, and
thumbnail stage breakdown
- Retry button per task for failed embeddings and tagging jobs
- Completed-task notifications (system tray via tauri-plugin-notification)
- Scan errors shown inline; WalkDir permission errors protect existing
records from deletion rather than cascading data loss
## Backend correctness
- sqlite-vec DML performed outside transactions throughout (virtual-table
limitation); embedding revision incremented on delete as well as insert
- Tagging job discard checks status = 'processing' so paused jobs reset
to 'pending' are also skipped, not just cancelled ones
- Stale async responses in Lightbox guarded with cancellation flags and
currentImageIdRef for both tag-load and tag-add callbacks
- Duplicate cache cleared on reindex; folder-removal clears vector rows
outside transaction before deleting the folder row
- Fix root cause: embedding_source_path() returns Result<PathBuf>, returning
Err for videos without a thumbnail instead of silently falling back to the
raw .mp4 path that CLIP cannot decode
- indexer: split embedding batch into pre-failed (no source) and embeddable
jobs; pre-failed are marked immediately without hitting the CLIP model
- db: retry_failed_embedding_jobs skips videos still without a thumbnail so
they no longer re-fail immediately on retry
- Add get_failed_embedding_images command listing failed files + error per folder
- Gallery: amber warning badge on tiles with embedding_status = 'failed'
- BackgroundTasks: fetch and show failed filenames/errors in expanded panel
- Toolbar: conditional 'Failed Embeddings' amber filter pill shown when any
folder has embedding_failed > 0; filters at DB level via new
embedding_failed_only param on get_images / count_images
- TagCloud: replaced vocabulary/dictionary label system with representative
image thumbnails per cluster; results cached in SQLite by image-id hash
Introduces an Explore view with a tag cloud that clusters image embeddings
using cosine k-means and labels clusters via vocabulary-nearest-neighbour
CLIP matching. Vocabulary embeddings are disk-cached (FNV hash-keyed) to
avoid redundant inference. Enables CUDA for candle dependencies and adds a
build.rs check that surfaces a clear error when the toolkit is missing.
