A file title or album name decrypted from server data could name a path
outside the chosen directory (`../../.ssh/authorized_keys`). One module,
src/filename.ts, now makes such names safe for `quak get`/`get-thumb`
without `--out`, downloadFile/downloadThumbnail without outPath, and the
backup and metadata backup trees. Originals-cache extensions are limited to
letters and digits. A user-supplied path is still used as is. decryptFile
reads a missing or non-string title as "" and rejects metadata that is not
a JSON object.
Model: opus-5-5
Adds Library.fresh(): forces a refresh, awaits its completion and persist, then returns the albums/photos/timeline read namespaces now reflecting a completed server round trip — the caller awaits and is guaranteed current at resolve. Default reads and the background loop are unchanged (immediate-from-cache). Concurrent fresh reads coalesce to one in-flight refresh; a fresh read whose refresh fails rejects rather than answering stale. The CLI adopts fresh reads separately (#52).
Model: opus-4-8
Precaches aggressively inside open(): every thumbnail (newest first, through the shared thumbnail pool, never evicted; visible/ahead requests preempt the background fill) and the pinned originals — the favorites album plus every file within precacheOriginalsDays (default 7) of the newest takenAt — through the content pool. The pinned set integrates with the #47 eviction hook; when the window moves or a favorite is removed, files become ordinary evictable originals. open() options precacheThumbnails/precacheOriginals/precacheOriginalsDays; progress via onProgress/status().
Model: opus-4-8
Adds lib.mldata search over the CLIP index (#49): forFile returns a file's stored payload; similar ranks nearest files by cosine on the CLIP embedding; searchByEmbedding ranks the index against a caller-supplied query vector. All RAM-only, reusing the packed Float32Array index and id list. No text encoder is bundled — the caller provides the query embedding. (Redo of the reverted first attempt, now tsc-clean.)
Model: opus-4-8
Bounds the originals cache and evicts least-recently-used. cacheOriginalsMaxBytes default 100 GiB; the effective limit adapts down via fs.statfs to keep freeBelowBytes (default 50 GiB) free. Over-limit writes evict unpinned originals oldest-mtime-first (mtime touched on read); pinned files (favorites + latest week) are skipped and an over-budget on-demand fetch proceeds over-limit. Every in-flight write is excluded from eviction, so concurrent fetches never delete each other's just-stored file. Only cacheDirectory/originals is evicted; downloadDirectory and thumbnails never.
Model: opus-4-8
Adds the on-disk content and thumbnail cache keyed by fileID: originals/ and thumbnails/ under cacheDirectory, present-means-complete (streaming atomic rename), orphan temp reaping on open. Photo.original/thumbnail return a cached path with no network when present, else fetch through the shared request pool; thumbnails.ensure drives the thumbnail pool with priority, dedup and AbortSignal. One shared RequestPools set serves both the ML fetch and the content cache. Content-hash integrity is deferred (#68); authenticated streaming decrypt guarantees integrity now.
Model: opus-4-8
Reverts the #50 merge (224bd101): mlsearch.ts failed tsc in the CI build (make check does not run make build, so it slipped past review). next restored to green; #50 to be redone with make build in its gate.
Model: opus-4-8
Adds lib.mldata search over the CLIP index (#49): forFile returns a file's stored payload; similar ranks nearest files by cosine on the CLIP embedding; searchByEmbedding ranks the index against a caller-supplied query vector. All RAM-only, reusing the packed Float32Array index and id list. No text encoder is bundled — the caller provides the query embedding.
Model: opus-4-8
Adds the machine-learning (magic) data layer: fetches per-file ML payloads (face detections + CLIP embeddings) via the existing metadata-backup fetch through the metadata pool after each refresh, decrypts and gunzips them, and stores one mldata/<fileID>.json per file by rename (present-means-complete). A derived index (mldata/clip.f32 + clip.json) loads in one read and is rebuilt whenever it disagrees with the payloads on disk in either direction, so an interrupted backfill self-heals. Never in metadata.json; incremental on later refreshes; progress via onProgress/status.
Model: opus-4-8
Adds the in-process read surface, served from RAM with args-object signatures: albums (list/byName/byID), photos (byID/records -> plain PhotoRecord[]), thin Album/Photo wrappers, and timeline.groups (day/week/month) with a PhotoFilter (albumID/text/fileTypes/hasLocation/includeArchived; hidden excluded). Week keys use ISO YYYY-Www; each file appears once per group, newest first. Built on the #43 snapshot projection; no network.
Model: opus-4-8
Adds three independent bounded request pools — metadata (10 in flight), content (5), thumbnails (25), each overridable — with on-demand-before-background priority and in-flight dedup (a shared key runs once); an idle pool never lends slots, and retries run inside a slot. Self-contained module; the content cache wires it into the library later.
Model: opus-4-8
Adds a synchronous, key-free snapshot() returning LibrarySnapshot (one PhotoRecord per fileID, deduped, newest first) with edited-name/time precedence (pubMagicMetadata over basic metadata) in milliseconds, plus AlbumRecord (favorites identified by type). subscribe({onChange}) delivers LibraryChange (changed/removed albums and files, refreshedAt) only when a refresh changes something; unsubscribe stops delivery. Built on the existing refresh loop; served from RAM, safe to send over IPC.
Model: opus-4-8
Library.open loads metadata.json and serves reads from RAM: an empty cache awaits the first refresh, an existing cache returns at once and refreshes in the background so an unreachable server never stalls open(). A background timer refreshes every refreshIntervalSeconds (default 3), diffing only changed albums via the resumable cursor+tombstone enumerators and rewriting metadata.json only when something changed. A refresh failure is invisible to reads and surfaced via status()/onProgress; a failed save keeps status().lastError set and retries until one lands, so a stale disk is never masked. No sync()/refresh()/serverReachable surface; status() and close() included.
Model: opus-4-8
Adds the metadata.json store: loads whole into RAM with id-lookup Maps, rewrites whole through the exported fsync atomic writer (temp, fsync, rename, dir fsync); a missing, unparseable, or wrong-schema file loads as empty (it is a cache); directory 0700, file 0600. No lock file, no public sync().
