Filename/tag search treated literal % and _ in query text as SQL
wildcards; escape them (with ESCAPE '\') before building LIKE patterns.
Also pass -- before the URL in curl invocations so a URL starting with
a dash can't be misread as an option.
A shared test_support module in db.rs provides the fixture: sqlite-vec
registered via auto-extension, an in-memory connection with foreign keys
on, and both migrations applied - no refactoring of production code
needed since every query function already takes &Connection.
db.rs coverage: folder idempotency, upsert_image update semantics
(favorite/rating preserved, AI tag state invalidated), the get_images
filter matrix with pagination and count_images agreement, tag
merge/rename/delete, user-tag precedence over AI tags in update_ai_tags,
album CRUD with FK cascade, the embedding job queue (backfill, retry,
consistency repair), tag search, and delete_folder cascades.
vector.rs coverage: pack/unpack round-trip, embedding upsert/delete with
dimension validation, and find_similar_image_ids ranking on both the
global KNN and folder-scoped brute-force paths.
Debounce Explore tag refreshes while AI tagging is active so the tag cloud catches up after worker activity settles instead of continuously re-querying.
Optimize the tag cloud aggregate query by fetching representative thumbnails in one pass and adding a supporting tag/image index.
Add a reset_ai_tags backend command that removes AI-generated tag rows, clears AI tagging metadata, cancels active tagging jobs, and drops queued or failed tagging jobs in the selected scope.
Expose reset actions in AI Workspace and the Explore tag manager, refresh gallery/progress/tag state after reset, and add subtle AI source indicators to tag manager rows.
Pass the active colour filter through tag searches and apply the existing palette match inside the tag query and count paths.
Update the UI Lab mock backend so colour filtering behaves the same way when testing tag search results.
The visual k-means cluster feature was confusingly named tag_cloud / tagCloud /
TagCloud across the whole stack, while the actual tag list is explore_tags — the
two were trivially easy to mix up (and did cause confusion). Rename the cluster
side to visual_cluster / visualCluster / VisualCluster everywhere: command
get_tag_cloud -> get_visual_clusters (+ lib.rs registration and the invoke
string), VisualClusterEntry, the store fields/actions/tokens, and the mock
backend. Old names are retired rather than reused, so any missed reference fails
loudly instead of silently resolving to the wrong concept.
The tags side keeps its accurate explore_tags naming, and the user-facing
"Tag Cloud" UI label is unchanged.
Also rename the SQLite tag_cloud_cache table -> visual_cluster_cache (the old
table is dropped during schema setup — it is a disposable cache already
invalidated by the clustering version bump) and the TagCloud.tsx component file
-> ExploreView.tsx, since it is the Explore container hosting both the cluster
and tag views.
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 an editable AI tag removal list and apply it to WD/JoyTag output before tags are stored. Clean existing generated AI tags during database migration while leaving manual user tags untouched.
Add dominant-color palette extraction, storage, filtering, and startup backfill so the gallery and Timeline can be filtered from the toolbar color picker.
Introduce a reusable tooltip component and migrate the color filter, update indicator, and gallery filename hover affordances to it.
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.
Albums (manual collections):
- New albums/album_images tables with FK cascades; DB functions and Tauri
commands for create/rename/delete/delete-many/reorder/list, add/remove
images, and paginated get_album_images.
- Distinct sidebar "ALBUMS" section with cover thumbnails, create/rename/
delete, and a Manage multi-select mode for bulk album deletion.
- Album view reuses the gallery grid (activeView "album" + selectedAlbumId);
spans folders; add from the bulk bar or the lightbox, remove from within.
Gallery multi-select + bulk actions:
- gallerySelectedIds selection model with a top-left corner checkbox that
reveals on corner hover; click-to-toggle in selection mode, double-click
to open.
- Floating BulkActionBar: tag (inline autocomplete popover), rating,
favorite, add-to-album, and a delete with an explicit "from disk"
confirmation. Batch commands bulk_update_details/bulk_add_tags/
bulk_remove_tag.
Also:
- Duplicate Finder delete now requires confirmation with clear "from disk"
wording (was single-click fire-and-forget).
- CPU/CUDA build-variant badge in Settings (get_build_variant).
- Rating/favorite no longer re-sorts derived collections (similar/region/
semantic/tag/album results); single and bulk paths replace in place there.
- Album-aware indexed-images/media-updated handlers so thumbnails paint and
newly-indexed files don't leak into an album view.
- CHANGELOG updated.
Route AVIF thumbnail generation through the bundled FFmpeg path instead of the Rust image decoder, avoiding unsupported-format failures without requiring system dav1d dependencies.
Requeue existing AVIF jobs that previously failed with unsupported-format errors and feed generated JPEG derivatives to embedding/tagging preprocessing while leaving lightbox display on the original AVIF file.
Drops and recreates the sqlite-vec tables at the current model dimension, then
re-queues every image for embedding. Fixes "dimension mismatch" search errors
that occur when the vector table was built for a different model/dimension (e.g.
after experimenting with 768-dim models against this 512-dim build).
The rebuild runs under the embedding worker's DB write lock and resets the job
queue inside a single transaction, so it can't interleave with an in-flight
embedding batch (per code review).
Add a failed-tag discovery flow for background worker failures.
Changes:
- Add a Failed Tags toolbar filter that appears when tag failures exist.
- Add Locate buttons for failed tag tasks in the background worker prompt.
- Route Locate to the affected folder and filter the gallery to images with tagger errors.
- Fetch and display failed tag filenames/errors in the expanded worker details.
- Add a backend query and gallery filter flag for images with failed AI tagging.
- Improve subtle-light contrast for failed worker chips, filenames, and Locate/Retry buttons.
- Also slightly increases the title bar update indicator pulse size for better visibility.
Timeline:
- Add a right-edge scrubber (year labels + month dots) that jumps to any
period; runs in the same direction as the scrolled content
- Load the full filtered set in Timeline view so the scrubber spans the whole
library instead of just the first page
Gallery & UI:
- Virtualise the gallery grid
- Folder reordering in the sidebar (drag + persisted sort_order) and a themed
dropdown component
- Subtle Light theme contrast fixes for toggles, secondary buttons and the
update toast
Embedding workers now defer video jobs without a thumbnail at claim time and
requeue any previously-failed deferred jobs on startup, so videos no longer
churn through failed embeddings.
QoL polish across BackgroundTasks, DuplicateFinder, Lightbox and VideoPlayer.
Phase 5 of the 0.1.0 release prep:
- FFmpeg no longer blocks startup (or crashes the app offline): provisioning
runs in a background thread emitting throttled ffmpeg-progress events,
with installed/downloading/failed state queryable via get_ffmpeg_status
and a retry command
- video jobs are invisible to claiming and tier-priority checks until FFmpeg
is ready, so they wait as pending without failing — and without starving
image embeddings/tagging (include_videos gating in db.rs)
- 7-step show-don't-tell onboarding wizard: welcome + live FFmpeg progress,
real first-folder picker, faked animating pipeline bar, placeholder
gallery tiles, cycling search-syntax demo, views overview, and an AI
features step with a real opt-in tagger download
- skippable at every point (Escape included), persisted via
settings/onboarding_completed.txt, re-runnable from Settings > General,
which also gains an FFmpeg status/retry row
Auto-fix pass (uninlined format args, needless borrows, to_vec,
size_of_val, map_err->inspect_err) plus hand fixes: fully annotated the
sqlite-vec transmute (c_char for cross-platform correctness), type alias
for the duplicate-scan tuple, slice signatures over &mut Vec/&PathBuf,
and #[allow(dead_code)] documenting the intentionally dormant caption
worker. The CI clippy step now fails on any new warning.
Workers now form a priority pipeline (thumbnails -> metadata ->
embeddings -> tagging): a worker only claims jobs when no
higher-priority tier has claimable work, so stages drain one at a time
at full speed instead of all workers contending for CPU (shared rayon
pool), disk, and the DB writer simultaneously.
Each tier gate is a single read-only EXISTS query per idle tick using
the same exclusion set the corresponding claim would (that worker''s
paused folders plus actively-indexing folders), so paused or mid-scan
work never blocks lower tiers, and failed jobs stop gating once they
leave pending. Deferred workers wake within one backoff interval
(250-750ms) of the higher tier draining.
A watcher-driven trickle of new files briefly pauses lower tiers by
design. A user-initiated tag run during a large embedding backlog
waits for it; pausing embeddings per folder overrides if tags are
wanted first.
Delete thumbnails alongside DB rows in all three removal paths (watcher
detect, delete-from-disk command, remove-folder command) so orphans no
longer accumulate passively.
Intercept RenameMode::Both watcher events and handle them as in-place
path updates: renames the thumbnail file to the new hash and updates the
DB row without touching the embedding, avoiding a full rebuild on move.
Falls back to thumbnail regeneration if the file rename fails.
db.rs:
- Move idx_images_taken_at creation to after ensure_column so it never
runs against a schema where taken_at doesn't exist yet; this was causing
a startup panic on any DB that predates Phase 1
- COALESCE(taken_at, created_at) → COALESCE(taken_at, modified_at) since
created_at is never populated (modified_at is always set)
- Remove dead is_tagging_job_cancelled function (superseded by
is_tagging_job_processing) and unused thumbnail_path from ImagePathRecord
indexer.rs:
- Watcher create path now calls update_folder_count after commit_batch and
emits folder-counts-changed so the sidebar count stays in sync; the
notification is only emitted when the DB write actually succeeds
store.ts / Timeline.tsx:
- compareImages taken_asc/taken_desc: fall back to modified_at not
created_at (created_at is always null)
- Timeline groupImages: same fallback fix so images group by month
correctly for libraries not yet re-indexed for EXIF
- subscribeToProgress: listen for folder-counts-changed and call
loadFolders() to keep the sidebar image count live
Monitors all registered folders using OS-native events (ReadDirectoryChangesW
on Windows) so new, modified, and deleted files are reflected in the gallery
automatically without manual reindexing.
Key design points:
- Adaptive blocking: recv() when no events pending (zero CPU), switches to
recv_timeout(earliest_deadline) only when debounce timers are running — wakes
exactly when the soonest event is ready, no busy-polling
- 500 ms per-path debounce coalesces rapid OS event bursts into one action
- Change detection preserved: build_record skips upsert if file_size + mtime
unchanged, preventing spurious thumbnail/embedding re-queues and avoiding
clobbering of existing metadata like thumbnail_path
- Access events (reads) filtered out; only Create/Modify/Remove trigger work
- Deletion path: emits watcher-deleted event with image IDs; frontend removes
those images from state and clears selectedImage if it was deleted
WatcherHandle stored in app state; add_folder / remove_folder / update_folder_path
commands keep the watched path set in sync with the DB.
Adds EXIF date extraction during indexing so photos can be sorted by when
they were actually taken, not just when the file was modified on disk.
- Add `taken_at` (nullable TEXT, ISO 8601) column to the images table via
ensure_column migration and a new idx_images_taken_at index
- Populate taken_at in build_record via extract_exif_date, which tries
DateTimeOriginal → DateTimeDigitized → DateTime tags and rejects all-zero
sentinel dates written by uninitialised cameras
- upsert_image uses taken_at = excluded.taken_at so a re-indexed file gets
fresh EXIF; stale dates from replaced files are not preserved
- Add taken_asc / taken_desc sort using COALESCE(taken_at, created_at) so
images without EXIF gracefully fall back to their creation date
- Surface as "Taken: newest / oldest" in the Toolbar sort dropdown
- Shift map_image_row column indices after the new taken_at (index 10)
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
- add semantic text search with toolbar mode switching and sqlite-vec query support
- improve embedding progress visibility, failure recovery, and similar-image affordances
- add search clearing and keyboard controls for filename vs semantic search modes
- refine background task interactions and gallery/lightbox embedding states
Refs: #4
- add Candle + HF Hub CLIP image embedding pipeline with background embedding worker
- write image embeddings into sqlite-vec and expose similar-image lookup through a new backend command
- surface embedding progress and recovery in the UI, including retries for failed embeddings
- improve gallery/lightbox embedding UX and make similar-image actions directly accessible
Refs: #3, #4
Sets up Tauri v2 + React frontend with SQLite metadata store,
sqlite-vec for CLIP embedding infrastructure, and r2d2 connection
pool replacing the single Arc<Mutex<Connection>>. Indexer now uses
rayon for parallel file metadata collection.
