List remote snapshots without requiring the private key (closes #64)
ListSnapshots built its table entirely from the local SQLite index. The
only remote access, reportRemoteDrift, was gated on AgeSecretKey != "",
so on a correctly configured host - which by design holds no private key
- snapshot list never contacted the destination store at all. A user who
lost their local index could not see their own backups, and the
"<remote only>" cell the README documents was unreachable dead code.

The listing is now the union of the local index and the destination
store, with no age_secret_key gate. Remote-only snapshots cannot have
their hostname or name recovered - RemoteSnapshotKey is one-way and the
manifest stores the hash - so they are listed by abbreviated remote key
with the real timestamp and compressed size from the manifest, and
"<remote only>" in the two columns that require the local index. Nothing
new is written to remote storage and the human ID is never fabricated.

An unreachable destination degrades to local-only with a warning and a
zero exit code. remote_present is null rather than false in that case,
so "absent" and "unknown" stay distinguishable and no drift is claimed
from a listing that never happened.

Also:

- Snapshot timestamps are normalised to UTC in scanSnapshotRows, the
  single point where they enter the domain. Previously one of three
  scanners omitted .UTC(), so on a non-UTC host the same snapshot
  rendered a different time depending on whether it was locally tracked.
- The 1000-row cap and the unreadable-manifest count are reported in
  --json mode as well as table mode, so machine consumers cannot be
  silently truncated. The JSON shape is unchanged.
- Warnings raised while listing are routed to stderr rather than the
  logger, which writes to stdout and would corrupt the JSON document.
  This is a local workaround for the logger bug tracked in #82 and
  should be removed when that lands.
- downloadManifestByKey is now the only remote manifest reader, so the
  manifest privacy question in #81 has a single call site to change.
- The orphaned "vaultik snapshot cleanup" hint now names vaultik prune;
  that command was folded into prune by the 2026-07-02 consolidation.

- 2026-08-09: Made `snapshot list` list the destination store without
the private key (issue #64). The listing is now the union of the
local index and a single streamed listing of the `metadata/` prefix,
with no `age_secret_key` gate — the manifest is unencrypted, so a
host holding only the public key can enumerate its own backups and a
host that lost its local index can still see them. A remote-only
snapshot's hostname and name are deliberately not recovered (they are
not recoverable without the private key, and making them so would
undo the privacy property tracked in issue #81); such rows are
labelled by an abbreviation of their remote key and carry the real
timestamp and compressed size from the manifest, with `<remote only>`
in the two columns that require the local index. Local-only snapshots
are reported as drift, and the hint now names `vaultik prune`, which
exists, instead of `vaultik snapshot cleanup`, which does not.
`reportRemoteDrift` collapsed into the merged view. Every remote
manifest read in the codebase now goes through
`downloadManifestByKey`, so issue #81 has one call site to change.
Review rework: snapshot timestamps now normalize to UTC in
`scanSnapshotRows`, the one place they enter the domain, so the merged
TIMESTAMP column cannot show local time for a locally tracked row and
UTC for a remote-only row on a non-UTC host; `GetIncompleteByHostname`
was folded onto that same scanner. `--json` now reports the
unreadable-manifest count and the 1000-row truncation on stderr
instead of returning a silently short document (the document's shape
is unchanged). The two per-snapshot `log.Warn` calls on the listing
path now route through the same JSON-aware writer as the existing
workaround, so one corrupt manifest can no longer put a log line on
stdout ahead of the document and break `| jq` — still a local
workaround pending issue #82. Verified with `script/cibuild` and with
an uncached `make check` (`0 issues.`, no cached test packages), plus
end to end against a `file://` destination with no secret key present.
- 2026-08-09: Closed the gap between `make lint` and CI (issue #78).
`script/lint` now runs the digest-pinned `golangci-lint` image taken
from the `Dockerfile` lint stage, which is the single source of truth
for the linter version; the duplicate pin in the `Makefile` `deps`
target and the unpinned `golangci-lint` install in `script/bootstrap`
are gone. A `golangci-lint` on `PATH` is used only when its version is
exactly the pinned one (which is how the lint stage runs it inside the
container); anything else goes through Docker, and a missing or
unreachable Docker daemon is a hard error rather than a silent
fallback. `make check` is therefore now as trustworthy as
`script/cibuild`.
- 2026-08-09: Finished the lint remediation under the canonical
`.golangci.yml` (issue #61, which also unblocks issue #59). The
remaining findings were fixed behavior-preservingly: `wsl_v5`
whitespace, `sqlclosecheck`, and `prealloc`. The `sqlclosecheck` sites
now close `sql.Rows` in a deferred closure instead of via the
`CloseRows` helper, which the linter could not see through. Only the
`revive` package-name findings remain suppressed, with per-site
`//nolint` directives; the package-rename question behind them is
tracked in issue #76. Verified with `script/cibuild`, which exits 0 —
that is the only trustworthy gate, because `script/lint` runs whatever
`golangci-lint` happens to be on `PATH` rather than the pinned
v2.12.2 that CI and the `Dockerfile` use, so `make check` can report
green on findings CI still fails. That tooling gap is tracked in issue
#78.
- 2026-08-09: The earlier next step "reconcile the uncommitted
`ARCHITECTURE.md` edits on `main`" needed no work: the working tree is
clean and `ARCHITECTURE.md` is committed on `main`.
- 2026-08-07: Updated golangci-lint to v2.12.2 everywhere it is pinned
(`Dockerfile` lint stage, `Makefile` deps target), replaced
`.golangci.yml` with the canonical config (v2 schema, `default: all`),
and remediated the bulk of the lint findings it surfaced (issue #61):
behavior-preserving fixes across every package, 2,990 findings down to
80. `make test` and `make fmt-check` were green at that point but
`make lint` was still red; the commit message claiming `make check`
was green was wrong.
- 2026-08-07: Added the standard `.golangci.yml` and `.editorconfig`
(issue #59); lint findings under the new config are tracked in issue
#61. `script/bootstrap` now installs sqlite3 (needed by tests).
- 2026-07-07 Adopted scripts-to-rule-them-all: `script/` entrypoints,
Makefile shims, README Entrypoints section
- 2026-07-02: Consolidated CLI verbs, retired overlapping commands; bound
the local index to its backup destination URL.
- 2026-06-28: snapshot rm now removes metadata only and prints the prune
command; restore skips chown when running as non-root.
- 2026-06-26: Snapshot IDs hashed at the storage boundary; snapshot list
made resilient to bad remote entries.
- 2026-06-24: Collapsed snapshot prune into vaultik prune; restore streams
blobs to disk and restores files in blob-locality order; cron output
fixes.
- 2026-06-17: Restore overhaul: ReadAt chunk reads from cached blobs,
reference-counted blob sweeper, integration tests; new internal/ui
output layer, banner, and progress lines.
- 2025-12-18: Added ARCHITECTURE.md and godoc coverage for exported API.
- 2025-07-26: End-to-end integration tests; manifest format refactor;
renamed backup to snapshot; afero filesystem abstraction.
- 2025-07-20: Initial design and implementation: cobra + fx CLI skeleton,
SQLite index database, UUID blob storage with streaming chunking.
# Future Steps
- Define remaining scope for a first tagged release and cut v0.1.0.
