Refuse to create a vault that already exists (closes #74 )

vault.CreateVault now checks for the vault before writing anything and fails with "vault NAME already exists" (vault.ErrVaultExists). secret init and secret vault create call it while holding the state directory lock, so two creates at once cannot both pass the check. Before, either command over an existing vault replaced its metadata, passphrase unlocker and longterm.age, so none of its secrets could be decrypted. Both commands now ask for the unlocker passphrase before creating the vault, so one stopped at that prompt leaves no vault without an unlocker behind, which they would then refuse to create again. The lock tests set up the vault "work" instead of "default", which init now refuses to create again. Model: opus-5-5

 # secret - Local Secret Manager

 key architecture for storing and managing sensitive data. It supports

 unlock mechanisms, and provides secure storage using the `age` encryption
 library.
-## Getting Started
+## Core Architecture
 Build from source, then install the binary as `~/bin/secret`:
 ```bash
 git clone https://git.eeqj.de/sneak/secret.git
 cd secret
 make build     # writes the binary to ./secret
 make install   # builds it and copies it to ~/bin/secret
 ```
 Generate a mnemonic, create the default vault, then store and read a secret:
 ```bash
 secret generate mnemonic   # prints a new BIP39 mnemonic; write it down
 secret init                # asks for that mnemonic and an unlocker passphrase
 echo "my-password" | secret add myservice/password
 secret get myservice/password
 ```
 ## Rationale
 I created `secret` to scratch an itch: I wanted a secure key/value store to
 replace a bunch of PGP-encrypted files in a directory structure. It could be
 used as a password manager, but was not designed as one.
 ## Design
 ### Three-Layer Key Hierarchy

-1. **Long-term Keys**: Derived from BIP39 mnemonic phrases, these provide the

 ### Version Management
 Each secret maintains a history of versions, with each version having:
 - Its own encryption key pair
- Metadata including creation time and validity period, encrypted to the
+- Metadata (unencrypted) including creation time and validity period

 - Immutable value storage
-
+- Atomic version switching via symlink updates
 The secret's `current` file names its current version. Switching versions
 replaces that file in one rename, so it is never half-written.
 ### Vault System

+contexts (work, personal, projects).
 ## Installation
 Build from source:
 ```bash
 git clone <repository>
 cd secret
 make build
 ```
 ## Quick Start
 1. **Initialize the secret manager**:
   ```bash
   secret init
   ```
   This creates the default vault and prompts for a BIP39 mnemonic phrase.
 2. **Generate a mnemonic** (if needed):
   ```bash
   secret generate mnemonic
   ```
 3. **Add a secret**:
   ```bash
   echo "my-password" | secret add myservice/password
   ```
 4. **Retrieve a secret**:
   ```bash
   secret get myservice/password
   ```

 `secret unlocker remove` destroy data that exists nowhere else. On a terminal
 each one first asks `[y/N]`, naming exactly what it is about to remove, and goes
 ahead only on `y` or `yes`; any other answer, a bare Enter included, cancels and
 removes nothing. The question is asked only after the command's checks have
 passed, and before it changes anything.
 Whether to ask is decided by stdin, where the answer is read from, so
 `secret rm foo | tee log` still asks. When stdin is not a terminal, as in a
 script or a CI job, nobody is there to answer: the command fails at once,
 removes nothing, and says to pass `--force`.
 `--force` (`-f`) removes without asking, whatever the command removes: a vault
 that holds secrets and the last unlocker of a vault included. Scripts that
 remove things pass `--force`.

 environment (on Linux, from `/proc/<pid>/environ`). Every child process of the
 shell or script that sets them inherits them, `gpg` included. Set on a command

 each one as soon as it has read it, so that the programs it runs itself, such as

 - 2026-10-04: Tests check which error a failure returns with `errors.Is`,
  not by matching words of its message
  (https://git.eeqj.de/sneak/secret/issues/49). Every exported error that
  can be returned has a test that the function returns it, and errors
  wrapping a cause are checked through the wrapping. Checks that still match
  text, because the error has no exported value the test can name, are
  listed on the issue.
 - 2026-10-04: When a vault cannot be opened through its current unlocker,
  because a file the unlocker needs is missing or damaged, its keychain item
  or Secure Enclave key is gone, or the passphrase is wrong, the error now
  ends by naming the vault, saying that it still opens with its mnemonic,
  and that `secret unlocker add passphrase`, run with `SB_SECRET_MNEMONIC`
  set to it, gives the vault a new unlocker; for a vault that is not the
  current one, as in `secret move` between vaults, it says to run
  `secret vault select` first (https://git.eeqj.de/sneak/secret/issues/47).
  Before, it ended with the bare cause. The advice is given only when the
  vault metadata records the key the mnemonic derives, so not for a vault
  created without a mnemonic, and not when the passphrase could not be read
  at all. `secret vault import` is not named: it refuses a vault that has a
  long-term key. `secret encrypt` and `secret decrypt` now read the key
  secret through `vault.GetSecret`, as `secret get` does, so they give the
  same advice; `Secret.GetValue`, the other way to get the long-term key, is
  removed. When a secret's `current` file cannot be read, the error says
  that `secret version list` lists its versions and `secret version promote`
  makes one current. The causes stay wrapped.
 - 2026-10-04: An unlocker's ID is the name of its directory in `unlockers.d`,
  so no two unlockers of a vault share one
  (https://git.eeqj.de/sneak/secret/issues/98). Before, a keychain or Secure
  Enclave unlocker's ID was its creation time to the minute and the host name,
  and a passphrase unlocker's the time to the minute, so two created within a
  minute shared an ID, and `unlocker select`, `unlocker remove` and the
  selection `unlocker add` makes acted on the older one. A PGP unlocker's ID
  was `pgp-` and its key's fingerprint; a second PGP unlocker for a key is
  still refused, now by comparing the fingerprint in the other unlockers'
  metadata. `unlocker list` and the shell completion of `unlocker select` and
  `unlocker remove` take each ID from the directory the unlocker was read
  from, no longer by matching metadata, so two unlockers with the same
  metadata are listed apart; an unlocker of an unknown type is listed under
  its directory name, and completion now offers Secure Enclave unlockers too.
  The keychain and Secure Enclave code was type-checked by
  `script/lint-darwin`, never run; a test on Linux lists, completes, selects
  and removes each of two passphrase unlockers with the same metadata by its
  own ID.
 - 2026-10-04: README's Storage Architecture, `secret version promote`,
  Technical Details and Testing text matches the code
  (https://git.eeqj.de/sneak/secret/issues/102). `current` and
  `currentvault` are plain files holding a name, not symbolic links; a
  version's metadata is the encrypted `metadata.age`; the state directory is
  `berlin.sneak.pkg.secret` in the user's configuration directory, not
  `~/.local/share/secret`, and holds the `lock` file. Also corrected: the
  code sets up no Touch ID for the keychain or Secure Enclave unlocker, and
  the Secure Enclave only decrypts; per-version keys give no forward
  secrecy; `pub.age` is not age-encrypted; vault metadata holds no vault
  name. Testing lists only `make test`.
 - 2026-10-04: `secret init` and `secret vault create` create a vault whole or
  not at all (https://git.eeqj.de/sneak/secret/issues/105).
  `vault.CreateVault` now takes the unlocker passphrase too, writes the vault
  directory with its metadata, long-term public key and passphrase unlocker,
  `longterm.age` included, into a temporary directory, renames that into
  `vaults.d` once it is complete, and only then makes the vault current.
  Before, either command killed after the passphrase prompt but before the
  unlocker was written left a vault with no unlocker, which `vault create` had
  already made current and which neither command would create again. Killed
  part-way now, it leaves no vault, and the next command that takes the lock
  deletes the temporary directory; or, killed between the rename and making
  the vault current, a complete vault that is not current, which
  `secret vault select` makes current.
 - 2026-10-04: A failed `secret unlocker add keychain` or
  `secret unlocker add secure-enclave` no longer leaves its keychain item or
  Secure Enclave key behind (https://git.eeqj.de/sneak/secret/issues/89).
  `CreateSecureEnclaveUnlocker` gets the long-term key before it creates the
  Secure Enclave key, so that a wrong passphrase creates none, and deletes the
  key again if encrypting with it or writing the unlocker then fails.
  `macse.CreateKey` finds the new key's hash right after `sc_auth` creates
  it, and fails with an error naming the key's label if it cannot; it deletes
  the key again if getting its public key then fails. The Objective-C was only
  read, never compiled or run, and so was `macse_darwin.go`, which is cgo only.
  `CreateKeychainUnlocker` writes all of the unlocker's files, the metadata
  among them, before it stores the item in the keychain, and deletes the item
  again if moving the unlocker into place then fails. A failure to delete is
  reported along with the first error. The tests of this run only on macOS:
  the Secure Enclave one in a build with cgo on a Mac with a Secure Enclave,
  the keychain one in a build with cgo.
 - 2026-10-04: What a command killed part-way left under a `.tmp-` name
  (https://git.eeqj.de/sneak/secret/issues/75), the temporary directories
  of `secret.TempDirFor` and the temporary files of
  `secret.WriteFileAtomic`, encrypted keys included, is deleted by the next
  command that takes the state directory lock. Before, it stayed until
  deleted by hand. A command writes `finished` into the lock file just
  before it releases the lock; the next one to take the lock searches only
  when it does not find that, so after a command that finished nothing is
  searched, however many secrets and versions there are. The search looks
  in the state directory, each vault, each secret and each version, the
  only directories those helpers make them in. A command that only reads
  takes no lock and deletes nothing. A failure to delete is warned about
  and the command goes on. An unlocker directory with no metadata file was
  already removed by `secret unlocker remove` given its directory name; a
  test now shows it.
 - 2026-10-04: An age identity's private key goes into a locked buffer
  through `secret.IdentityToLockedBuffer` everywhere
  (https://git.eeqj.de/sneak/secret/issues/38): the vault's long-term key
  when a passphrase, PGP, keychain or Secure Enclave unlocker is created,
  the new unlocker's own key, a new secret version's key, and the key
  `secret encrypt` generates. Before, each place converted the string age
  returns to bytes and left the string in ordinary memory. The function
  moves the string's own bytes into the buffer, which overwrites them; the
  copies age makes while writing the string remain, as its comment says.
  The 1.0 memory-security entry below no longer lists these places,
  `internal/cli/crypto.go` among them, nor `version.go:155`, which was
  `internal/secret/version.go`, not `internal/cli/version.go`.
 - 2026-10-04: `script/lint-darwin` (`make lint-darwin`) runs `go vet` and
  `golangci-lint` in docker on the code as a macOS build compiles it
  (`GOOS=darwin`), with cgo off
  (https://git.eeqj.de/sneak/secret/issues/50). `script/check` runs it, and
  the `Dockerfile` lint stage runs its commands, so `script/cibuild` does too.
  Before, CI on Linux never compiled the files built only for macOS. Compiling
  cgo code for macOS needs Apple's SDK headers, and both `internal/macse` and
  `github.com/keybase/go-keychain` are cgo on macOS. So the three functions
  that call `go-keychain` moved from `keychainunlocker.go` to
  `keychainunlocker_cgo.go`, built only with cgo on macOS like
  `macse_darwin.go`. A macOS build without cgo, which before did not compile,
  gets `keychainunlocker_nocgo.go` and the `macse` stub instead, whose errors
  say the keychain or Secure Enclave needs a macOS build with cgo. The check
  covers the rest of the keychain unlocker, the Secure Enclave unlocker and
  the macOS-only tests other than `keychainunlocker_test.go`, whose lint
  findings are fixed. For the length and complexity limits, parts of
  `GetIdentity`, `getLongTermPrivateKey` and `CreateKeychainUnlocker` moved
  into functions of their own, and the Secure Enclave unlocker derives the
  long-term key from the mnemonic through the same function as the keychain
  unlocker instead of a copy of it. Lines over 88 columns in the files the
  check cannot see are wrapped.
 - 2026-10-04: `secret rm`, `secret version rm`, `secret vault remove` and
  `secret unlocker remove` ask `[y/N]` before removing anything
  (https://git.eeqj.de/sneak/secret/issues/39), naming what they remove: the
  secret, its vault and its version count; the version, secret and vault; the
  vault and its secret count; the unlocker, its vault and whether it is the
  last, and for the last the vault's secret count and that the vault then
  opens only with its mnemonic. Only `y` or `yes` goes ahead. Without
  `--force`, a command whose stdin is not a terminal fails at once. `--force`
  (now also on `rm` and `version rm`) removes without asking; it replaces the
  old refusals to remove a vault with secrets or the last unlocker of one
  without `--force`, which the question now covers. The checks run, and the
  question is asked, before the state directory lock is taken; under the
  lock the checks run again, and if they would ask a different question,
  nothing is removed. `secret rm` fails when it cannot count the versions.
 - 2026-10-04: A crash while an unlocker is being replaced no longer leaves a
  current unlocker that cannot open the vault
  (https://git.eeqj.de/sneak/secret/issues/71). Every new unlocker gets a
  directory of its own, named with the time to the nanosecond:
  `passphrase-<time>`, `<host>-pgp-<time>`, and for a keychain or Secure
  Enclave unlocker the keychain item or Secure Enclave key, which names the
  directory, carries the time instead of the day. `secret.WriteDir` fails on a
  directory that exists instead of writing into it. `unlocker add passphrase`
  writes the new unlocker, makes it current, and only then removes the vault's
  other passphrase unlockers; a crash between the last two steps leaves the old
  one beside the new, and the old passphrase still opens the vault through it
  until the next `unlocker add passphrase` or an `unlocker remove` removes it.
  A PGP, keychain or Secure Enclave unlocker added on the same host and day as
  another of its type is added beside it instead of replacing it.
 - 2026-10-04: `SB_SECRET_MNEMONIC` and `SB_UNLOCK_PASSPHRASE` are read once
  per command, in its `RunE`, into locked buffers on the CLI `Instance`, and
  unset at once, so that no program the command runs, `gpg` included,
  inherits them (https://git.eeqj.de/sneak/secret/issues/60). Nothing below
  the command reads the environment; the buffers are passed down:
  `vault.CreateVault` takes the mnemonic (nil for none), a `Vault` derives its
  long-term key from its `Mnemonic` and gives its `UnlockPassphrase` to a
  passphrase unlocker, and the PGP, keychain and Secure Enclave unlocker
  constructors take both. `CreatePGPUnlocker` sets both on the vault it
  loads, through `SetMnemonic` and `SetUnlockPassphrase`, now part of
  `VaultInterface`, before calling its `GetOrDeriveLongTermKey`. `init` and
  `vault create` no longer put the mnemonic into the environment. Unsetting
  erases nothing: the starting environment (`/proc/<pid>/environ`) and
  memory still hold the value. The README warns against both variables.
 - 2026-10-04: `.golangci.yml` is again the canonical file from
  `sneak/prompts`, byte for byte
  (https://git.eeqj.de/sneak/secret/issues/66). It runs `gomodguard_v2`
  in place of the deprecated `gomodguard`, so the lint no longer warns,
  and enables `depguard` with a rule that keeps `net/http/httptest` out of
  non-test files. Neither raised a finding in this repo.
 - 2026-10-04: `secret unlocker add pgp` works on Linux
  (https://git.eeqj.de/sneak/secret/issues/88). `CreatePGPUnlocker` gets
  the vault's long-term key as adding a passphrase unlocker does, with the
  vault's `GetOrDeriveLongTermKey`, now part of `VaultInterface`: from the
  mnemonic, checked against the vault, or else from the current unlocker.
  Before, it used the keychain unlocker's helper, which on every platform
  but macOS always failed. A test adds a PGP unlocker for a throwaway GPG
  key, getting the long-term key once from the mnemonic and once from a
  passphrase unlocker, and reads a secret through the new unlocker.
 - 2026-10-04: A vault name may use only lowercase ASCII letters, digits,
  `.`, `-` and `_`, and must not be empty, `.` or `..`
  (https://git.eeqj.de/sneak/secret/issues/68); the error and `README.md`
  state the rule. `vault create`, `vault import`, `vault select`,
  `vault remove`, both vault names of `mv` and shell completion of a
  `vault:secret` argument check the name as typed with
  `vault.ValidateVaultName` before building any path from it. Before,
  `vault import ..` wrote a long-term key and an unlocker into the state
  directory itself, and `vault select ..` made that the current vault.
 - 2026-10-04: `script/cibuild` runs the checks again on an unchanged
  tree (https://git.eeqj.de/sneak/secret/issues/54). It passes the
  current time as the `CHECK_EPOCH` build argument, which both the lint
  and the build stage of the `Dockerfile` declare after their module
  download, so the `RUN` steps below the argument run again on each
  build while the base images and module downloads stay cached. Before,
  a second run on the same tree took every check from the build cache
  and reported success having run nothing.
 - 2026-10-04: A failed unlocker add no longer leaves a partial unlocker
  directory (https://git.eeqj.de/sneak/secret/issues/48).
  `secret unlocker add pgp` resolves the GPG key's fingerprint once, for
  its duplicate check, and passes it to `CreatePGPUnlocker` to record.
  `CreatePGPUnlocker` and `CreateKeychainUnlocker` get the long-term key
  and encrypt everything before writing anything. All four unlocker
  types write their files through `secret.WriteDir`: a new unlocker is
  built in a temporary directory, renamed into place when complete and
  removed on a failure.
 - 2026-10-04: `secret unlocker select` and `secret unlocker remove`
  skip, with the warning `unlocker list` gives, an unlocker directory
  whose metadata file cannot be checked for, read or parsed, instead of
  failing when it sorts before the unlocker asked for. Such a directory,
  or one without a metadata file, is removed by its directory name, the
  name the warning gives; only the directory is removed, since its type
  is unknown. Removing one whose metadata file is missing or corrupt
  never counts as removing the last unlocker. Removing one whose metadata
  file cannot be checked for or read always does, since it may be the
  only working unlocker, so in a vault with secrets it needs `--force`.
 - 2026-10-04: A failed command prints its error once, without the usage
  text after it (https://git.eeqj.de/sneak/secret/issues/41). Usage is
  still printed for a command called wrongly: wrong number of arguments,
  unknown flag, bad flag value, missing required flag, or flags that
  break a flag group (mutually exclusive, required together, one
  required). The root command's `PersistentPreRunE` turns usage off.
  Cobra checks arguments and flag values before that hook but required
  flags and flag groups only after it, so the hook checks those two
  first. Root `SilenceUsage` would have hidden usage for all of these.
 - 2026-10-04: `secret get` keeps the secret in locked memory until it
  writes it out (https://git.eeqj.de/sneak/secret/issues/37):
  `Vault.GetSecret` and `Vault.GetSecretVersion` return a
  `*memguard.LockedBuffer`, which every caller destroys, and `secret get`
  writes its bytes straight to stdout, still with no trailing newline.
  Before, the value was copied into ordinary memory that nothing wiped,
  and `get --version` also wrote it to the debug log.
 - 2026-10-04: The `Makefile` no longer sets `DOCKER_HOST`, so its docker
  targets use the local docker daemon, or whatever `DOCKER_HOST` the
  environment sets. `make build` calls the new `script/build`, which
  stamps the version (`VERSION` from the environment, else
  `git describe`) and the git commit as before. `build`, `clean`,
  `install` and `docker-run` are in `.PHONY`; `make install` depends on
  `build`. The `vet` target is gone: `script/test` runs `go vet` first.
 - 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.
