--ml fetches face detections and CLIP embeddings from the /files/data/fetch
endpoint (type 'mldata'). Each blob is encrypted with the file's key and
gzipped; we decrypt with decryptBlob, gunzip, and include the parsed JSON
as 'mlData' in the per-file output. Fetched in batches of 200 file IDs.
--exif downloads each file, runs sharp().metadata() to extract image
properties (format, dimensions, color space, orientation), then parses
the raw EXIF buffer with exif-reader for structured tags (lens, ISO,
shutter, aperture, GPS altitude, etc.). Also captures raw IPTC, XMP,
and ICC profile data. Included as 'imageMetadata' in the per-file output.
Without either flag, behavior is unchanged (fast metadata-only dump).
Adds exif-reader 2.0.3 as a runtime dependency.
3 new tests (ML data decrypted, ML data absent when flag not set, EXIF
extraction). 119 total tests, all green.
New command: quak backup-metadata <dir>
Dumps every piece of decrypted account metadata into a directory tree
of plain JSON files without downloading any file content. Layout:
<dir>/
account.json { email, userID }
collections/
<id>-<name>/
_collection.json { id, name, type, pubMagicMetadata?, ... }
<fileID>.json { id, metadata, magicMetadata?, pubMagicMetadata? }
Also adds collection-level magic metadata decryption (magicMetadata,
pubMagicMetadata, sharedMagicMetadata) to decryptCollection, which was
previously only done for files. The server sends these for visibility
settings, sort order, cover photo selection, etc.
6 new tests covering: account.json, per-collection dirs with
_collection.json, collection pubMagicMetadata decryption, per-file
JSON with all three metadata layers, graceful handling of files with
no magic metadata, and incremental re-run safety. 116 total.
