# Status

pre-1.0. No git tags. TODO.md carries open 1.0 security blockers. Work in
flight on branch secure-enclave-unlocker (clean tree as of 2026-07-06).

# Next Step

Bring the repo into policy compliance in one commit:

- Add fmt-check and hooks targets to the Makefile (test/lint/fmt/check/
  docker already exist).
- Add REPO_POLICIES.md and .editorconfig.
- Add .gitea/workflows/check.yml running make check.
- Verify Dockerfile base images are pinned by sha256.

# Completed Steps

- 2026-10-04: `.gitignore` is the org's standard file, which ignores
  `.env`, `.env.*`, `*.pem` and `*.key` and editor and OS files, plus
  this repo's `/secret`, `*.log`, `*.test` and `settings.local.json`
  (https://git.eeqj.de/sneak/secret/issues/40). `.dockerignore` also
  leaves out `node_modules`; `.git` stays in the build context for the
  version stamp.
- 2026-10-04: `secret init` refuses when the default vault exists, and
  `secret vault create NAME` when `NAME` does, with "vault NAME already
  exists", before writing anything. The check is in `vault.CreateVault`,
  which both commands call while holding the state directory lock, so two
  creates of one vault at once cannot both pass the check. Before, either
  command replaced the vault's metadata, passphrase unlocker and
  `longterm.age`, so none of its secrets could be decrypted any more. Both
  commands now ask for the unlocker passphrase before creating the vault,
  so one stopped at that prompt leaves no vault behind.
- 2026-10-04: The `internal/cli` tests are back to about their time
  before the state directory lock
  (https://git.eeqj.de/sneak/secret/issues/80). The test that each
  changing command waits for the lock releases it as soon as it sees the
  command waiting there, instead of after a fixed 100 ms. The two vaults
  with passphrase unlockers that the path and move tests start from are
  made once and copied for each test.
- 2026-10-04: `secret mv` rejects a move whose destination is the source
  under another name, such as `foo` for `Foo` on a case-insensitive
  filesystem (the macOS default) or a name reached through a symbolic
  link, before changing anything, with or without `--force`, within a
  vault and between vaults; before, `--force` removed the destination and
  so deleted the secret. A rename that changes only letter case works on a
  case-sensitive filesystem as before.
- 2026-10-04: Lint runs only in docker: `script/lint` builds
  `Dockerfile.lint`, where golangci-lint is a build step rebuilt on
  every run (`--no-cache-filter`), so an unchanged tree is linted too;
  the module download stays cached. `script/bootstrap` no longer
  installs golangci-lint, and the `Dockerfile` lint stage calls it
  directly instead of `make lint`. `golangci-lint config verify` is not
  run: it fetches its schema live over unpinned HTTPS.
- 2026-10-04: A PGP unlocker whose metadata has no usable GPG key ID
  no longer panics: `GetID()` warns with the unlocker's directory and
  returns `pgp-unknown`. `ListUnlockers` skips, with a warning, an
  unlocker whose metadata file cannot be checked for, read or parsed
  instead of failing, so `secret unlocker list` still lists the others;
  the listing's ID lookup no longer warns about that directory again.
- 2026-10-03: `secret mv` rejects a move whose destination is the
  source (`mv --force x x`, `mv --force work:x work:`, or an empty
  destination, which defaults to the source name) before changing
  anything; before, `--force` removed the destination first and so
  deleted the secret. Every vault name given with `vault:` must be one
  of the existing vaults by exact name, so `work:x work/:x` is rejected
  instead of being taken for a move between two vaults. A move within a
  named vault no longer makes that vault the current one, whether it
  succeeds or fails.
- 2026-10-03: Commands that change the state directory hold one lock
  (`flock` on `lock` in the state directory; a mutex on the in-memory
  test filesystem), so concurrent commands no longer lose versions or
  race on the current pointers. Every file is written through
  `secret.WriteFileAtomic` (temporary file, sync, rename), so no file
  is ever half-written and `current`, `currentvault` and
  `current-unlocker` never go missing. New versions, new secrets and
  cross-vault copies are built in a temporary directory and renamed
  into place, and removals rename out of the way first, so a version
  or secret is never half-added and never half-removed. An
  interrupted command can still leave:
    - a broken unlocker, when it was replacing one: an unlocker added
      under the directory name of an existing one is rewritten file by
      file. That happens to a passphrase unlocker added to a vault that
      has one, and to a PGP, keychain or Secure Enclave unlocker added
      on the same host and day as another of its type
      (https://git.eeqj.de/sneak/secret/issues/71);
    - from `init` or `vault create` killed after the passphrase prompt
      but before the unlocker is written, a vault with no unlocker,
      which `vault create` has already made the current vault;
    - from an unlocker add stopped before its metadata is written, a
      directory that `unlocker list` warns about and `unlocker rm`
      cannot remove;
    - data under a `.tmp-` name in the state directory: a secret or
      version being added, or the secret, version, unlocker or vault
      being removed, encrypted keys included. Nothing deletes it; it
      must be deleted by hand
      (https://git.eeqj.de/sneak/secret/issues/75).
- 2026-10-03: The checks run before changing a vault now stop with an
  error naming the path and cause when they cannot read what they
  inspect, instead of reading the failure as "nothing there": the
  duplicate check before `unlocker add pgp` (an unreadable
  `unlockers.d` or unlocker metadata file), the secret count that
  guards removing the last unlocker and removing a vault, and the
  existing long-term key check before `vault import`.
- 2026-10-03: `version rm`, `version promote` and `get --version`
  accept a version only if it is one of the versions `version list`
  lists for that secret, compared as typed before any path is built
  (`secret.VersionExists`), and touch nothing otherwise. An empty
  `--version` is rejected instead of meaning the current version.
  Before, `secret version rm x ../../..` deleted the whole vault,
  `secret version rm x ..` the secret, and `.` or `""` every version.
- 2026-10-03: Key material is wiped on every exit: `Entry()` returns
  the exit code after its deferred `memguard.Purge()` has run, and only
  `main` calls `os.Exit`. SIGINT and SIGTERM go through memguard's
  handler, which wipes every buffer before exiting; when the process is
  in the terminal's foreground process group it first restores the
  terminal settings from startup, so an interrupted passphrase prompt no
  longer leaves echo off.
- 2026-10-03: Every command that builds a path from a secret name
  checks the name first with `vault.ValidateSecretName` and touches
  nothing when it is invalid: `rm`, `mv` (both names, within a vault
  and between vaults, before switching the current vault), `import`,
  `version list`/`promote`/`rm`, `encrypt` and `decrypt`. The error
  and `README.md` state the naming rule. Before, `secret rm ..`
  deleted the whole vault and `secret rm .` every secret in it.
- 2026-10-03: The keychain unlocker's age key passphrase stays in
  locked memory: it is generated into a locked buffer, and the
  keychain JSON is written and read by `KeychainData` code in
  `internal/secret/keychaindata.go` (tested on Linux) without
  `encoding/json` holding it; the JSON field names are unchanged.
- 2026-10-02: A plain `docker build .` builds again: the size tests
  skip a case that needs more locked memory than the process can
  lock, and run every case under `script/cibuild`. The image stamps the
  `VERSION` build argument, else `git describe --tags --always`, into
  `Version`, and fails if `.git` is present but yields no version;
  `make build` stamps `git describe` too, not a fixed `0.1.0`.
  `.dockerignore` keeps `.git/config` out; `script/docker` is the
  canonical copy.
- 2026-08-07: Updated golangci-lint to v2.12.2 with the canonical
  `.golangci.yml` (all linters enabled minus the standard disable
  list, `lll` 88, tests linted); bumped the `Dockerfile` lint-stage
  image to the tagged v2.12.2 Debian digest; fixed all ~1550 new
  findings across `internal/` and `pkg/` (line wrapping, `wsl_v5`
  blank lines, sentinel errors for `err113`, `t.Parallel()` where
  safe, `_test` package conversions, complexity/`dupl` helper
  extraction) on branch `golangci-v2.12.2`. Reworked after review:
  the `err113` sentinels in `internal/vault`, `internal/secret`,
  `internal/cli` and `pkg/bip85` were reshaped so every composed
  error message is byte-identical to `main`, and
  `findUnlockerIDByMetadata` now returns an error so `unlocker list`
  skips an unreadable `unlockers.d` entry with a warning instead of
  emitting a fabricated fallback ID.
- 2026-07-07 Adopted scripts-to-rule-them-all: `script/` entrypoints,
  Makefile shims, README Entrypoints section
- 2026-03-11: Secure Enclave unlocker for hardware-backed secret
  protection, plus review fixes (stub panics, derivation index, tests,
  README) on branch secure-enclave-unlocker.
- 2026-02-28: Repo cleanup, removed stale .cursorrules and coverage.out.
- Audit fix wave (issues #1, #2, #3, #13, #14): skip unlockers with
  missing metadata, allow uppercase secret names, fix hardcoded
  derivation index, validate names in GetSecretVersion against path
  traversal, return errors instead of panicking, add Warn() on silent
  anomalies.
- Memory security hardening: LockedBuffer used through encrypt/decrypt
  paths (Save/EncryptWithPassphrase/GetValue/gpg helpers), deprecated
  bare-[]byte APIs removed.
- Per-secret keypair architecture, vault package refactor, versioning
  with --version, comprehensive test suite with in-memory filesystem.
- Debug logging system (slog, GODEBUG flag, TTY-aware output).
- Renamed SEP unlocker to Keychain, reorganized import commands.
- 2025-05-28: Initial implementation (vault, age encryption, mnemonic,
  CLI).

# Future Steps

- Compliance (after Next Step lands): keep main green under the new
  .gitea workflow; run make check before every merge.
- Implement version-number shell completion for the second arg of
  `secret version promote` and `secret version rm`
  (`internal/cli/version.go`; was an in-code TODO removed for godox).
- Cover mnemonic-vs-xprv identity consistency in
  `pkg/agehd/agehd_test.go` `TestMnemonicVsXPRVConsistency` (was an
  in-code FIXME removed for godox).
- Darwin-gated files (`internal/secret/keychainunlocker.go`,
  `seunlocker_darwin.go`, `internal/macse/macse_darwin.go`, related
  tests) are not linted on the Linux CI runner and still contain lines
  over the new 88-column limit; they will surface if lint ever runs on
  macOS.
- Merge secure-enclave-unlocker to main once review is done.
- 1.0 critical security blockers (from repo TODO.md):
    - Command injection: GPG key IDs passed unescaped to exec.Command
      (pgpunlocker.go:323-327); data.String() passed unescaped to the
      security command (keychainunlocker.go:472-476).
    - Memory security: age identity .String() creates unprotected
      copies (keychainunlocker.go:356, pgpunlocker.go:256,
      version.go:155); age secret key held in a plain string in
      cli/crypto.go:86,91,113; private keys exposed via buffer.Bytes()
      to GPGEncryptFunc and EncryptWithPassphrase.
    - Input validation: no maximum secret size (DoS).
    - Timing attacks: bytes.Equal passphrase compare (cli/init.go:
      209-216); non-constant-time public key compare (vault.go:95-100).
- High priority:
    - Secure temporary file handling and cleanup.
    - Print cobra usage only for argument errors, not internal
      failures.
    - Initialize a default unlock key at vault creation.
    - Confirmation prompts for destructive operations (keys rm, vault
      deletion).
    - Add secret rm and vault deletion commands.
- Medium priority:
    - Standardize error messages; stop leaking internals.
    - Graceful handling of corrupted or missing key files with recovery
      suggestions.
    - Validate GPG key existence before creating PGP unlock keys.
    - Split oversized CLI functions.
    - Document env var security (SB_UNLOCK_PASSPHRASE,
      SB_SECRET_MNEMONIC); clear after use.
    - mlock/munlock for sensitive allocations.
- Cleanups: read statedir from environment or default instead of
  passing it around.
- Enhancements: help examples, shell completion, colored output,
  --quiet flag, name suggestions on miss, audit logging, hardware
  integration tests (Keychain, GPG), naming consistency, vault
  export/import, batch operations, search, secret metadata
  (descriptions, tags).
