clawbot af9ac6d979 Rename the Go module to sneak.berlin/go/secret (closes #43)
check / check (push) Failing after 2s
Details 
REPO_POLICIES.md requires the module root sneak.berlin/go/<name>.
go.mod, every import (rewritten with gofmt -r), the -X flags in
script/build and the examples in the pkg READMEs now use the new path.
go mod tidy lists go-humanize and fatih/color as direct requirements,
since internal/cli imports them.

This breaks anyone who fetched or imported git.eeqj.de/sneak/secret:
they must switch to sneak.berlin/go/secret, which resolves to this
repository.

clawbot 047f347955 Format and check markdown with prettier in make fmt and fmt-check (closes #110)
check / check (push) Failing after 3s
Details 
script/fmt and script/fmt-check follow the model scripts in the prompts
repo: Go as before, plus prettier over every markdown file with 4-space
tabs and proseWrap always. Prettier is pinned by hash in package.json and
yarn.lock; script/bootstrap now installs node, yarn and prettier. The
Dockerfile lint stage copies node and yarn from a node image pinned by
hash and runs script/bootstrap, so its make fmt-check fails the build on
unformatted markdown. Every markdown file is formatted once; wording is
unchanged (CLAUDE.md's "*" list markers become "-").

clawbot 2503f2db96 Name only the mnemonic when it cannot be read (closes #115)
check / check (push) Failing after 2s
Details 
secret init and secret vault create read the mnemonic with the new
secret.ReadMnemonic, whose every error wraps the new
secret.ErrMnemonicNotRead. It shares the terminal read with ReadPassphrase,
whose errors still wrap ErrPassphraseNotRead. Without a terminal the error
names the environment variable that gives the value instead:
SB_SECRET_MNEMONIC for the mnemonic, SB_UNLOCK_PASSPHRASE for the
passphrase. A test pins the message of init without a terminal.

clawbot 43f66bf369 Give each failure one error value (closes #113)
check / check (push) Failing after 3s
Details 
internal/cli drops its copies of vault.ErrSecretNotFound, ErrVaultNotFound,
ErrVersionNotFound and ErrSecretExists and of the secret package's keychain
and Secure Enclave errors, and its second error for an unknown unlocker
type, an invalid mnemonic, a length below 1, an unsupported secret type and
an oversized secret. vault.ErrNilValueBuffer becomes
secret.ErrNilValueBuffer. Every error of secret.ReadPassphrase wraps
ErrPassphraseNotRead. ResolveGPGKeyFingerprint returns ErrGPGKeyNotFound for
a key the keyring lacks. storeInKeychain returns errNilDataBuffer. bip85's
ErrPasswordTooShort and ErrEncodedTooShort go with their unreachable checks,
as does the macOS check in macOS-only code. Tests that matched these
errors' text use errors.Is.

clawbot 176095e3d1 Check errors by identity, not by message text, in tests (closes #49)
check / check (push) Failing after 1s
Details 
Tests that asserted a failure by a fragment of its message now use
errors.Is: a refactor returning the wrong error, or wrapping with %v
instead of %w, now fails them. New tests return each exported error of
internal/vault and pkg/bip85 that no test returned, and check wrapped
causes (os.ErrNotExist, ErrMnemonicMismatch through GetSecret,
ErrInvalidPathComponent through DeriveBIP85Entropy). The 999-versions
test moves into package secret to name its unexported error. Checks of
errors no test can name keep their text; they are listed on the issue.

clawbot 2adc588ace Say the mnemonic still opens a vault its unlocker cannot (closes #47)
check / check (push) Failing after 2s
Details 
When a vault cannot be opened through its current unlocker, 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
gives it a new unlocker, after 'secret vault select' when it is not the
current vault. Only when the vault metadata records the key the mnemonic
derives, and not when the passphrase could not be read. 'secret encrypt'
and 'secret decrypt' read the key secret through vault.GetSecret, and
Secret.GetValue with its helpers is removed. An unreadable 'current'
file's error names 'secret version list' and 'secret version promote'.
Causes stay wrapped.

clawbot 0e6a4afb71 Make an unlocker's ID the name of its directory (closes #98)
check / check (push) Failing after 2s
Details 
Keychain and Secure Enclave unlocker IDs were the creation time to the
minute plus the host name, and passphrase unlocker IDs the time to the
minute, so two created within one minute shared an ID, and `unlocker
select`, `unlocker remove` and the selection after `unlocker add` acted on
the older one. Every unlocker's ID is now its directory name, unique in
its vault. `vault.ListUnlockers` returns each unlocker's metadata keyed by
that name, so `unlocker list` and shell completion no longer find IDs by
matching metadata. PGP unlocker IDs were `pgp-<fingerprint>`; a second
PGP unlocker for one key is refused by comparing fingerprints in metadata.

clawbot 1a23fd3125 Make the README's storage and file format text match the code (closes #102)
check / check (push) Failing after 2s
Details 
The directory tree shows `current` and `currentvault` as plain files holding
a name, a version's metadata as the encrypted `metadata.age`, the real state
directory under the user's configuration directory, and the `lock` file.
`version promote` rewrites `current`. File Formats tells unencrypted vault
and unlocker metadata from encrypted version metadata; `pub.age` is plain
text and vault metadata holds no vault name. Unlocker bullets lose Touch ID
claims the code does not set up, and the Secure Enclave only decrypts.
Per-version keys no longer claim forward secrecy. Testing lists only
`make test`.

Model: opus-5-5

clawbot 23dcea83f9 Create a vault whole in a temporary directory, then select it (closes #105)
check / check (push) Failing after 2s
Details 
vault.CreateVault takes the unlocker passphrase and writes the vault
directory, its metadata, long-term public key and passphrase unlocker
into a temporary directory, renames that into vaults.d once complete,
and only then makes the vault current. secret init and secret vault
create call it once instead of adding the unlocker afterwards, so a
kill part-way leaves either no vault, whose temporary directory the
next command that takes the lock deletes, or a complete one. A test
records the state directory before every change the call makes and
checks each state, and the command run again from it.

tabs, `proseWrap: always`) as well as the Go code, and `make fmt-check` checks
both, as the model scripts in the `prompts` repo do
(https://git.eeqj.de/sneak/secret/issues/110). Prettier is pinned by hash in
`package.json` and `yarn.lock`, and `script/bootstrap` installs node, yarn and
prettier. The `Dockerfile` lint stage copies node and yarn from a node image
pinned by hash and runs `script/bootstrap`, so its `make fmt-check` fails the
build on an unformatted markdown file. Every markdown file was formatted once,
wording unchanged.
- 2026-10-04: A mnemonic that cannot be read, in `secret init` and
`secret vault create`, gives an error that names the mnemonic only
(https://git.eeqj.de/sneak/secret/issues/115). It is read with
`secret.ReadMnemonic`, whose every error wraps the new
`secret.ErrMnemonicNotRead`; before, it was read with `ReadPassphrase`, so the
message said "failed to read mnemonic: failed to read passphrase:" and advised
setting `SB_UNLOCK_PASSPHRASE`. Without a terminal it now says "failed to read
mnemonic: stdin is not a terminal (piped input or script). Please set the
SB_SECRET_MNEMONIC environment variable or run interactively". The passphrase
messages no longer repeat "cannot read passphrase" after "failed to read
passphrase:", and empty input gives "nothing was entered".
- 2026-10-04: A failure returns the same error value whichever command hits it
(https://git.eeqj.de/sneak/secret/issues/113). `internal/cli` no longer keeps
its own copies of `vault.ErrSecretNotFound`, `ErrVaultNotFound`,
`ErrVersionNotFound` and `ErrSecretExists`: `secret mv`, `rm`, `decrypt`,
`vault import`, `vault remove` and `version list`, `promote` and `rm` wrap the
`vault` errors. `errUnsupportedUnlockerType` is removed: `secret unlocker add`
gives `errInvalidUnlockerType` for an unknown type, whichever check rejects
it. Off macOS, adding a keychain or Secure Enclave unlocker returns the
`secret` package's error for it, not an `internal/cli` copy; on macOS, the
check that the system is macOS is gone, as it could never fail.
`secret vault import` gives `errInvalidMnemonicPhrase` for an invalid
mnemonic, as `init` and `vault create` do. `secret generate secret` gives
`errLengthTooSmall` for a length below 1 wherever it is checked, and
`errUnsupportedSecretType` for `--type mnemonic` too. `secret import` of a
file over 100MB wraps `errSecretTooLarge`, as `secret add` returns it.
`vault.ErrNilValueBuffer` is replaced by `secret.ErrNilValueBuffer`, which
`secret` already returned under another name. Messages are unchanged, except
that `secret decrypt` of a missing secret says "not found", as `secret get`
does, not "does not exist"; `vault import` of an invalid mnemonic says
"invalid BIP39 mnemonic phrase"; `--type mnemonic` says "unsupported type:
mnemonic (use 'secret generate mnemonic' instead)"; and a file too large to
import says
`failed to read secret from file <path>: secret too large: exceeds 100MB limit`.
Every error of `secret.ReadPassphrase` wraps `secret.ErrPassphraseNotRead`,
which supplies the words "failed to read passphrase" that its callers used to
add themselves; so two passphrases that differ now give only "passphrases do
not match", the words now follow "failed to read mnemonic:" and "failed to
read passphrase confirmation:", and a terminal read error no longer repeats
them. A GPG key the keyring does not hold gives `secret.ErrGPGKeyNotFound`,
found by gpg's status line for "No public key"; before, the message repeated
"failed to resolve GPG key fingerprint" and ended in gpg's exit status. The
keychain unlocker returns `errNilDataBuffer` for nil data; this and its test
build only on macOS with cgo and were only read. `bip85.ErrPasswordTooShort`
and `ErrEncodedTooShort` are removed with their checks: 64 bytes of entropy
always give 86 Base64 or 80 Base85 characters, the most a password length may
ask for. Tests that matched these errors' text use `errors.Is`.
- 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.
