Docs and comments only; no behaviour change. Corrects ten overclaims the
security review found: snapshot names are hashed but the hash uses no
secret, so a guessed hostname and name can be confirmed; a blob is named
by hex(SHA256(SHA256(uncompressed contents))), stated once in
docs/REPOSTRUCTURE.md and referenced elsewhere; double hashing does not
hide known content (blob packing does); age uses ChaCha20-Poly1305, not
XChaCha20; encryption is required, not optional; a snapshot is marked
complete before its metadata is uploaded; the export comment now matches
its only caller; deep verify detects corruption, not authorship; adding a
recipient does not reach existing data; restore examples target a
user-owned directory.
Adds an Accepted Risks subsection under Security Considerations with the
seven documented risks, cross-referenced from the README.
Model: opus-4-8
config.example.yml carried a real-looking 20-char S3 access key id and 40-char secret, a private-address http:// endpoint, and a storage_url naming an internal rclone remote and pool path. Replace them with the same neutral placeholders the config init template uses: YOUR_ACCESS_KEY / YOUR_SECRET_KEY, a https://s3.example.com endpoint, a mybucket bucket, and rclone://myremote/path/to/backups. No behavior or other keys change.
The credentials live in the commented-out s3 block, which the loader never parses, so the new test reads the file raw text to assert the placeholders are present and no http:// endpoint remains, and also loads it to confirm the active storage_url still parses.
Model: opus-4-8
Validate only rejected blob_size_limit below chunk_size, but the chunker can emit chunks up to chunk_size times the FastCDC size spread (four times), and the packer puts a single chunk of any size into an otherwise empty blob. A limit between one and four times chunk_size therefore let a blob reach four times the configured maximum, with most blobs holding a single chunk and so exposing individual chunk lengths to anyone who can list the destination.
Validate now rejects blob_size_limit below chunk_size times the spread, reusing the chunker's one constant (now exported as ChunkSizeSpread) instead of a second literal. The rule is stated in the error text, the Validate comment, the README config table, config.example.yml, and the generated config template.
Model: opus-4-8
The --daemon flag, BackupInterval, FullScanInterval, MinTimeBetweenRun
config fields, and DirtyPath model were placeholders for a never-shipped
daemon mode and have been removed. Daemon mode is out of scope for 1.0.
- Implement deterministic blob hashing using double SHA256 of uncompressed
plaintext data, enabling deduplication even after local DB is cleared
- Add Stat() check before blob upload to skip existing blobs in storage
- Add rclone storage backend for additional remote storage options
- Add 'vaultik database purge' command to erase local state DB
- Add 'vaultik remote check' command to verify remote connectivity
- Show configured snapshots in 'vaultik snapshot list' output
- Skip macOS resource fork files (._*) when listing remote snapshots
- Use multi-threaded zstd compression (CPUs - 2 threads)
- Add writer tests for double hashing behavior
- Add internal/types package with type-safe wrappers for IDs, hashes,
paths, and credentials (FileID, BlobID, ChunkHash, etc.)
- Implement driver.Valuer and sql.Scanner for UUID-based types
- Add `vaultik version` command showing version, commit, go version
- Add `--verify` flag to restore command that checksums all restored
files against expected chunk hashes with progress bar
- Remove fetch.go (dead code, functionality in restore)
- Clean up TODO.md, remove completed items
- Update all database and snapshot code to use new custom types
- Changed blob table to use ID (UUID) as primary key instead of hash
- Blob records are now created at packing start, enabling immediate chunk associations
- Implemented streaming chunking to process large files without memory exhaustion
- Fixed blob manifest generation to include all referenced blobs
- Updated all foreign key references from blob_hash to blob_id
- Added progress reporting and improved error handling
- Enforced encryption requirement for all blob packing
- Updated tests to use test encryption keys
- Added Cyrillic transliteration to README
