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 set now prints only the key name after a write, never the value: a value may be a secret such as s3.secret_access_key, and echoing it leaks into captured stdout and pasted terminals. The set logic moves into writeConfigSet so this is testable.
config set also tightens a pre-existing group- or world-readable config to 0600 after writing; the previous stat-and-preserve-mode block had no effect (os.WriteFile does not change an existing file mode) and is removed.
ParseStorageURL now rejects s3:// and rclone:// URLs that carry credentials in the userinfo or an unknown query parameter, naming s3.access_key_id and s3.secret_access_key as where credentials belong. On a url.Parse failure only the inner cause is wrapped, so the raw URL is not echoed. file:// is unchanged.
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
With the s3.* config form and an endpoint written without a scheme, use_ssl being omitted built an http:// endpoint, while config.example.yml documented use_ssl as defaulting to true. Over plain HTTP a network observer sees manifests, object names, sizes and the access key id, and can alter responses.
use_ssl is now *bool: omitted (nil) means the default, TLS; only an explicit use_ssl: false forces plain HTTP. This matches the s3:// URL form, which already defaults to TLS. The config init template dropped its misleading use_ssl line from the s3:// block (that key is never read for URLs; ?ssl=false controls TLS there) and points at ?ssl=false instead.
Model: opus-4-8
Removes code and fixtures nothing uses: the internal/models package and its test, a second SnapshotInfo type in package cli that had no references (the live one is in internal/vaultik), and two config fixtures, test-config.yml and test/integration-config.yml, whose keys the config loader no longer accepts. test/config.yaml stays; a test uses it.
Also fixes config set, which rewrote the whole file with 4-space indentation on the first set despite the documented promise to preserve formatting. It now encodes with 2-space indent like the default template, and a test asserts comments and indentation survive a set.
Deviation: one commit, not one per deletion as the issue asked.

Updates golangci-lint to v2.12.2 everywhere it is pinned and installs the canonical `.golangci.yml`, then remediates every finding the new linter/config surfaces so `make check` is green.
## Version bump
- `Dockerfile` lint stage: `golangci/golangci-lint:v2.11.3-alpine` -> `v2.12.2-alpine` (digest-pinned, date comment updated)
- `Makefile` `deps` target: `go install` moved from the old v1 module path at `@latest` to the pinned `github.com/golangci/golangci-lint/v2/cmd/golangci-lint@v2.12.2`
- `.golangci.yml` replaced with the canonical config (v2 schema; settings under `linters.settings` so the thresholds actually apply; `default: all` with the standard six disables)
- `script/bootstrap` installs golangci-lint via the system package manager and carries no version pin, so it is unchanged
- CI (`.gitea/workflows/check.yml`) only runs `script/cibuild`, so it needed no change
## Lint remediation
The canonical config surfaced ~3,300 findings across 56k lines. All are fixed, behavior-preserving; incorporates and supersedes the per-package mechanical passes already merged to `main` (refs #61). Highlights:
- `err113`: dynamic errors replaced with package sentinels + `%w` wrapping; comparisons via `errors.Is`
- `goprintffuncname`: printf-style helpers renamed with an `f` suffix (`ui.Writer` message methods, `cli.ReportErrorf`, `database.Fatalf`) and all call sites updated
- `revive` stutter renames: `blob.Handler`, `blob.WithReader`, `blob.ChunkPosition`, `storage.URL`, `storage.Info`; missing doc comments added
- `contextcheck`/`noctx`: `context.Context` threaded through `blob.Packer` and the scanner call sites; context-aware `exec`/`sql` variants
- `funlen`/`cyclop`/`gocognit`/`dupl`: oversized and duplicated functions split into focused helpers (production and test code)
- tests: `t.Parallel()` added where safe (global logger init kept in the serial phase for `-race`), `t.TempDir()`/`t.Helper()` adopted, several suites converted to external test packages
- `gosec`: bounded integer conversions, `ReadHeaderTimeout` on the test HTTP server; remaining warnings suppressed per-site with justifications
- remaining `nolint` directives are rare, targeted, and each carries a reason (e.g. `nilnil` not-found contract in the repository layer, fx module globals, on-disk snake_case struct tags)
- removed the deprecated `log.LogOptions` alias (callers migrated to `log.Options`)
`make check` (tests with `-race`, lint, fmt-check) passes.

The CLI had two commands named "prune" doing different jobs (local
DB orphan cleanup vs. remote blob garbage collection), which was
confusing and forced a manual two-step workflow after deleting any
snapshot.
Single user-facing prune surface is now `vaultik prune`, which calls
PruneDatabase (local orphan cleanup) then PruneBlobs (remote unref
blob GC). Snapshot deletion paths (snapshot remove, snapshot remove
--all, snapshot purge) auto-run CleanupOrphanedData inline so the
local index database doesn't accumulate ghost rows after every
removal — the user observed ~39k orphaned files and 2 orphaned blobs
after a remove --all because that cleanup was previously a separate
opt-in command. `snapshot prune` is removed.
Also addresses the doc/help-string drift the user audit caught:
* cli/prune.go help text used to reference a non-existent
`vaultik purge` command.
* cli/config.go get/set short/long examples were S3-specific
(s3.bucket) when the primary storage configuration is
storage_url.
* vaultik/info.go printed S3 Bucket/Endpoint/Region labels
unconditionally; for file:// or rclone:// users those rows
were empty. The Storage Configuration block now prints the
storer's Type+Location first, the storage_url string when set,
and only emits S3 rows that are actually populated.
* vaultik/info.go's "Run 'vaultik prune --remote'" hint
referenced a flag that doesn't exist.
* vaultik/blobcache.go's doc comment claimed LRU eviction, which
is no longer the restore-time policy (the sweeper drives
eviction; LRU is the safety-net fallback when maxBytes is
finite).
* README.md listed `vaultik restore`, `vaultik snapshot prune`,
and `s3.bucket` example, all out of date.
README's roadmap section is rewritten with concrete pre-1.0 items
(security audit, error-condition tests, parallel blob downloads,
restart of interrupted restore, …) so the next-steps surface
matches what the project actually still needs.
The cleanup calls are guarded against a nil SnapshotManager so
tests that construct a bare Vaultik struct continue to work.
Module path changed from git.eeqj.de/sneak/vaultik to
sneak.berlin/go/vaultik (vanity redirect). All imports, ldflags,
Dockerfile, goreleaser config, and docs updated. App data/config
directories now use plain "vaultik" instead of the reverse-DNS name.
README:
- New copy-pasteable quickstart at top: go install, config init,
age keypair, config set for key + file:// destination, home backup
- All command names in command details are code-quoted
- config set/get gained sequence index support (age_recipients.0)
so lists are settable from the CLI
- Dockerfile build is CGO_ENABLED=0 to match the pure-Go build
The config command group manages the config file:
config init - write default config (moved from top-level init)
config edit - open the config in $EDITOR (falls back to vi)
config get - print a value by dotted YAML path (s3.bucket)
config set - set a scalar value by dotted YAML path
get/set operate on the yaml.Node tree so comments and formatting in
the config file are preserved across edits. set creates intermediate
maps as needed.
