A live photo, which Ente stores as one ZIP, is unpacked as it downloads
into its image and its video, each `<fileID>.<ext>` with its extension
from the ZIP, beside `<fileID>.livephoto.json`, which names the two.
Both are checked against the recorded hash and renamed into place only
when both are complete. A ZIP with a second image or video, or whose
parts come to more than 20 times its size plus 16 MiB, is refused. The
backup and the content cache count a live photo as stored only with both
files, album folders link both, `quak get` writes both, and the content
result gives the video as `videoPath`. A ZIP an earlier version stored
is replaced.
Model: opus-5-5
An original fetched for a backup is now written by the download writer
straight into the backup's originals/, and the content cache records it
there instead of keeping its own copy. One the cache already held is
still copied. `quak backup` opens its library with the thumbnail and
originals precache off, as the one-shot commands do.
Model: opus-5-5
The download writer's temp files are now named .quak-<pid>-<random>.tmp.
removeLeftoverTempFiles moves from the backup into the download module and
deletes a .quak-*.tmp file only when the process ID in its name is no
longer running; the content cache calls it at open() instead of deleting
every temp file, so a download in progress in another process sharing the
cache survives. The README backup layout and TODO.md are updated.
Model: opus-5-5
downloadFile, shared by quak get, the content cache and backup, hashes
the decrypted bytes (unkeyed BLAKE2b-512, standard base64) and stores
nothing on a mismatch, failing with an error naming the file ID. A live
photo ZIP is unpacked as it streams with fflate's Unzip, in small
slices so memory stays bounded however far an entry expands, and its
image and video hashed separately as <imageHash>:<videoHash>.
decryptFile reads the older imageHash/videoHash fields for live
photos. A file with no recorded hash is stored unchecked.
Model: opus-5-5
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
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
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.
