Details 
README gains Description, Getting Started, Rationale, Design, TODO and
License sections; its first sentence names the licence and author.
Installation and Quick Start become Getting Started; Core Architecture
becomes Design, whose two false version bullets (symlink switching,
unencrypted metadata) are corrected. README and AGENTS.md are wrapped
to prettier's settings.

TODO.md: Workflow and Next Step point at the 1.0.0 milestone and the
next branch, the old Next Step's four finished items move to Completed
Steps with their dates, and Future Steps loses the items already done.

# .dockerignore does NOT use .gitignore semantics. Docker matches with
# moby/patternmatcher: filepath.Match plus `**`, so `*` does not cross
# `/` and an unprefixed pattern is anchored at the context root. Every
# depth-independent pattern therefore needs `**/`, or `config/.env` and
# `certs/server.key` still ship while this file reads as solved. Only
# genuinely root-anchored entries go unprefixed. Never transplant these
# into .gitignore, where `**/` is wrong.
#
# Matching is case-sensitive, so secrets use character ranges rather
# than an ALL-CAPS twin, which would still miss `Server.Key`.
#
# Extend with this repo's own host-built artifacts, written anchored:
# `/myapp`, never `**/myapp`, which also matches `cmd/myapp/` and
# deletes the package directory from the context.
# .git is sent without its config. Without a VERSION build argument the
# stage that compiles runs `git describe --tags --always` on .git, which
# does not need .git/config; that file can hold a credential, such as a
# password in a remote URL or the token the CI checkout step stores there.
# Each submodule keeps a config with the same exposure in its git directory
# under .git/modules/, nested again for a submodule's own submodules, or in
# its own .git directory when it keeps one.
# KNOWN GAP: a submodule whose name has a `config` segment (`config`,
# `deploy/config`, `config/lib`) loses its whole git directory, because
# `**/.git/modules/**/config` also matches that segment's directory
# under .git/modules/. Go's version stamping then fails the build;
# nothing leaks. Name such a submodule without that segment:
# `git submodule add --name`.

# IMPORTANT RULES
* Claude is an inanimate tool. The spam that Claude attempts to insert into
commit messages (which it erroneously refers to as "attribution") is not
attribution, as I am the sole author of code created using Claude. It is
corporate advertising for Anthropic and is therefore completely
unacceptable in commit messages.
* Tests should always be run before committing code. No commits should be
made that do not pass tests.
* Code should always be formatted before committing. Do not commit
unformatted code.
* Code should always be linted and linter errors fixed before committing.
NEVER commit code that does not pass the linter. DO NOT modify the linter
config unless specifically instructed.
* The test suite is fast and local. When running tests, NEVER run
individual parts of the test suite, always run the whole thing by running
"make test".
* Do not stop working on a task until you have reached the definition of
done provided to you in the initial instruction. Don't do part or most of
the work, do all of the work until the criteria for done are met.
* When you complete each task, if the tests are passing and the code is
formatted and there are no linter errors, always commit and push your
work. Use a good commit message and don't mention any author or co-author
attribution.
* Do not create additional files in the root directory of the project
without asking permission first. Configuration files, documentation, and
build files are acceptable in the root, but source code and other files
should be organized in appropriate subdirectories.
* Do not use bare strings or numbers in code, especially if they appear
anywhere more than once. Always define a constant (usually at the top of
the file) and give it a descriptive name, then use that constant in the
code instead of the bare string or number.
* If you are fixing a bug, write a test first that reproduces the bug and
fails, and then fix the bug in the code, using the test to verify that the
fix worked.
* When implementing new features, be aware of potential side-effects (such
as state files on disk, data in the database, etc.) and ensure that it is
possible to mock or stub these side-effects in tests when designing an
API.
* When dealing with dates and times or timestamps, always use, display, and
store UTC. Set the local timezone to UTC on startup. If the user needs
to see the time in a different timezone, store the user's timezone in a
separate field and convert the UTC time to the user's timezone when
displaying it. For internal use and internal applications and
administrative purposes, always display UTC.
* When implementing programs, put the main.go in
./cmd/<program_name>/main.go and put the program's code in
./internal/<program_name>/. This allows for multiple programs to be
implemented in the same repository without cluttering the root directory.
main.go should simply import and call <program_name>.CLIEntry(). The
full implementation should be in ./internal/<program_name>/.
* When you are instructed to make the tests pass, DO NOT delete tests, skip
tests, or change the tests specifically to make them pass (unless there
is a bug in the test). This is cheating, and it is bad. You should only
be modifying the test if it is incorrect or if the test is no longer
relevant. In almost all cases, you should be fixing the code that is
being tested, or updating the tests to match a refactored implementation.
* Always write a `Makefile` with the default target being `test`, and with a
`fmt` target that formats the code. The `test` target should run all
tests in the project, and the `fmt` target should format the code. `test`
should also have a prerequisite target `lint` that should run any linters
that are configured for the project.
* After each completed bugfix or feature, the code must be committed. Do
all of the pre-commit checks (test, lint, fmt) before committing, of
course. After each commit, push to the remote.
* Always write tests, even if they are extremely simple and just check for
correct syntax (ability to compile/import). If you are writing a new
feature, write a test for it. You don't need to target complete coverage,
but you should at least test any new functionality you add.
* Always use structured logging. Log any relevant state/context with the
messages (but do not log secrets). If stdout is not a terminal, output
the structured logs in jsonl format. Use go's log/slog.
* You do not need to summarize your changes in the chat after making them.
Making the changes and committing them is sufficient. If anything out of
the ordinary happened, please explain it, but in the normal case where you
found and fixed the bug, or implemented the feature, there is no need for
the end-of-change summary.

contributor should be able to understand the entire development workflow by
reading the Makefile.
- Every repo should have a `Dockerfile`, and it carries the repo's gates: a
`lint` phase and a `test` phase, with the final stage depending on both so the
image cannot be built unless they pass. For non-server repos the final stage
brings up a development environment; for server repos it is the runtime image.
The gate phases and the build stage start from their pinned base images and
install what those images lack either inline, as the canonical Go `Dockerfile`
below does for `git`, or by running `script/bootstrap`, as the `prompts`
repo's own `Dockerfile` does for its yarn packages. The development
environment stage installs development prerequisites by running
`script/bootstrap` rather than duplicating its installs inline. A stage that
runs `script/bootstrap` COPYs `script/` and the dependency manifests
(`package.json` + `yarn.lock`, `go.mod` + `go.sum`, etc.) before running it.
- Every repo should have a `Dockerfile`. All Dockerfiles must run `make check`
as a build step so the build fails if the branch is not green. For non-server
repos, the Dockerfile should bring up a development environment and run
`make check`. For server repos, `make check` should run as an early build
stage before the final image is assembled. Dockerfiles install development
prerequisites by running `script/bootstrap` rather than duplicating installs
inline; COPY `script/` and the dependency manifests (`package.json` +
`yarn.lock`, `go.mod` + `go.sum`, etc.) before running it so the bootstrap
layer stays cached until dependencies change.
- **Linting and testing run in Docker, as phases of the `Dockerfile`.** There is
no separate lint file. `script/lint` and `script/test` each build one phase
and nothing else:
- **Dockerfiles must use a separate lint stage for fail-fast feedback.** Go
repos use a multistage build where linting runs in an independent stage based
on the `golangci/golangci-lint` image (pinned by hash). This stage runs
`make fmt-check` and `make lint` before the full build begins. The build stage
then declares an explicit dependency on the lint stage via
`COPY --from=lint /src/go.sum /dev/null`, which forces BuildKit to complete
linting before proceeding to compilation and tests. This ensures lint failures
surface in seconds rather than minutes, without blocking on dependency
download or compilation in the build stage.
```sh
docker build --no-cache --target lint -t "$(script/projectname)-lint" .
docker build --no-cache --target test -t "$(script/projectname)-test" .
```
**A stage that is not the last one in the file is built only when the final
stage's chain depends on it, or when `--target` names it.** That is why the
two gates are always invoked by name here, and why the final stage carries a
`COPY --from=` of a harmless file from each of them: without that edge a
plain `docker build .` builds the last stage alone and exits 0 having linted
and tested nothing.
**Every `docker build` in `script/` is tagged**, here and in
`script/cibuild` and `script/docker`. An untagged build leaves a dangling
image behind on every invocation, on every developer host and every CI
runner; a tagged one replaces the previous image.
Inside a phase the tool is invoked directly — `golangci-lint`, `go test`,
`eslint`, `prettier` — never through `make lint` or `script/test`, which are
themselves a `docker build` and would recurse into a daemon that does not
exist in a build step. Formatting is the exception and stays on the host:
`script/fmt` writes the working tree, and `script/fmt-check` is its
read-only twin.
**No lint verdict may come from a host invocation of the linter.** On a
shared host golangci-lint reads a result cache keyed on file content rather
than location, so a second checkout of the same content is served the first
one's findings, and a host-global lock in `$TMPDIR` makes concurrent runs
exit non-zero with `parallel golangci-lint is running` — a status a caller
cannot tell from real findings. Both have produced wrong verdicts in this
org, in both directions. A container has its own cache, its own `TMPDIR` and
a digest-pinned binary, so neither is reachable.
- **Any build that runs checks is built with `--no-cache`.** Docker invalidates
a `COPY` layer only when the copied content changes, so on an unchanged tree
the check `RUN` is served from cache, nothing executes, and the build still
exits 0. Every `docker build` in `script/` therefore passes `--no-cache`:
`script/lint`, `script/test`, `script/cibuild` and `script/docker` are the
four, and there is no fifth — `script/check` runs the two gate phases and
`script/fmt-check`, and builds no image of its own. A bare `docker build .` is
not evidence that anything ran: a sub-second build reporting success is a
cache hit, not a result. Never invalidate by pruning — `docker builder prune`
and friends destroy a build cache shared with every other build on the host.
When a check is added or changed, prove it works by planting a defect it must
catch and watching the run fail on it, then revert the defect. A green run
alone shows neither that the check ran nor that it covers what it should.
- **The gate phases are separate stages, and the build stage depends on both.**
The lint phase is based on the `golangci/golangci-lint` image (pinned by
hash), so lint failures surface in seconds rather than after a full compile,
and the test phase is based on the Debian Go image. The canonical Go repo
`Dockerfile`:

Key points:
- The lint phase uses the `golangci/golangci-lint` image directly (it has
both Go and the linter), so nothing needs installing.
- `COPY --from=<phase> /src/go.sum /dev/null` is a no-op copy whose only
purpose is the ordering edge. BuildKit runs stages in parallel by default,
and a stage nothing depends on is not built at all, so without these two
lines a red gate would not fail the build.
- Keep the runtime stage last, and if you add a stage after it, give it the
same two copies. A plain `docker build .` builds the last stage's chain
and nothing else.
- The lint stage uses the `golangci/golangci-lint` image directly (it
includes both Go and the linter), so there is no need to install the
linter separately.
- `COPY --from=lint /src/go.sum /dev/null` is a no-op file copy that creates
a stage dependency. BuildKit runs stages in parallel by default; without
this line, the build stage would not wait for lint to finish and a lint
failure might not fail the overall build.
- If the project uses `//go:embed` directives that reference build artifacts
(e.g. a web frontend compiled in a separate stage), the lint phase must
(e.g. a web frontend compiled in a separate stage), the lint stage must
create placeholder files so the embed directives resolve. Example:
`RUN mkdir -p web/dist && touch web/dist/index.html web/dist/style.css`.
- If the project requires CGO or system libraries for linting, install them
in the lint phase. The `golangci/golangci-lint` image is Debian-based and
has no `apk`, so install with `apt-get` under the Debian package name
(`libvips-dev`, where alpine says `vips-dev`), and delete the package
lists in the same `RUN`, so the layer does not keep them:
```dockerfile
RUN apt-get update \
&& apt-get install -y --no-install-recommends libvips-dev \
&& rm -rf /var/lib/apt/lists/*
```
- `.dockerignore` lets `.git` into the build context. It keeps out every git
`config` at any depth (`**/.git/config`, `**/.git/modules/**/config`): the
repository's own, each submodule's under `.git/modules/`, and that of a
submodule keeping its own `.git` directory. `git describe` does not need
them, and each can hold a credential: a password in a remote URL, or the
token the CI checkout step stores there. A submodule whose name has a
`config` segment (`config`, `deploy/config`, `config/lib`) loses its whole
git directory to `**/.git/modules/**/config`, and Go's version stamping
then fails the build: give it a name without that segment
(`git submodule add --name`). The stage that compiles has `git` (the
Debian Go image has it; an alpine one needs `apk add --no-cache git`) and
takes the version from the `VERSION` build argument when one is given,
otherwise from `git describe --tags --always`. That gives the tag on a
tagged commit; on a later commit, the tag, the number of commits since it
and the short commit (`v1.2.3-4-gabc1234`); and the short commit when no
tag is reachable. The stage that compiles also marks its working directory
safe for git (`git config --system --add safe.directory /src`): a context
sent as a tar stream keeps the sender's file owners, and git refuses a
checkout owned by another user, so the version would come out empty.
`ARG VERSION` has no default, and the build fails if the context carries
`.git` and the version still comes out empty, `dev` or `unknown`. A plain
`docker build .` with no build arguments must succeed; a Dockerfile that
refuses an empty build argument drops that refusal and keeps the argument.
The lint stage should not depend on the actual build output — it exists to
fail fast.
- If the project requires CGO or system libraries for linting (e.g.
`vips-dev`), install them in the lint stage with `apk add`.
- The build stage runs `make test` after compilation setup. Tests run in the
build stage, not the lint stage, because they may require compiled
artifacts or heavier dependencies.
- Every repo should have a Gitea Actions workflow (`.gitea/workflows/`) that
runs `script/cibuild` on push, and checks out the repo as its only other step.
That script bootstraps, runs the gate phases, and then builds the image, so a
successful run means every check passed; a bare `docker build .` does not
carry the same guarantee, because its gate phases may come from the cache. The
image build is uncached and so runs the gate phases a second time. That is the
price of the rule above, and it is worth paying: the image that ships is built
from a run of its own gates rather than from a cache entry. A separate
workflow limited to `main` by a `branches` list under `on: push` cannot be
checked by review: to try a change to it, add the feature branch to that list
and push, then remove the branch from the list again before merging. Keep any
job in it that publishes behind `if: github.ref_name == 'main'`, so the run
from the feature branch publishes nothing.

`-count=1` is required on both invocations: it defeats Go's test _result_
cache, so neither run can report a stored pass in place of running the

and no recompilation.
That cache is Go's own, separate from Docker's layer cache. Go stores a
passing result in its cache directory (`GOCACHE`), and when the same tests
run again on unchanged code it prints that result, marked `(cached)`,
without running them. That matters on a developer's machine, where this
target runs and the directory lasts from one run to the next. The `test`
phase of the `Dockerfile` needs no `-count=1`: its base image holds no
result for this repo's tests and nothing before its `go test` step runs a

- `.gitignore` should be comprehensive from the start: OS files (`.DS_Store`),
editor files (`.swp`, `*~`), in-repo agent scratch directories (`.claude/`),
language build artifacts, and `node_modules/`. Fetch the standard `.gitignore`
from `https://git.eeqj.de/sneak/prompts/raw/branch/main/.gitignore` when
setting up a new repo. These patterns are written to `.gitignore`'s own
semantics, in which an unanchored pattern already matches at every depth; they
are not a `.dockerignore` and must not be transplanted into one unmodified.
- **`.dockerignore` does not use `.gitignore` semantics, and copying patterns
across unmodified leaves secrets in the build context.** Docker matches with
`moby/patternmatcher`: `filepath.Match` semantics plus a `**` extension, so
`*` does not cross `/` and a pattern without a leading `**/` is anchored at
the build-context root. A `.dockerignore` listing `.env`, `*.pem` and `*.key`
therefore excludes only the copies at the repository root, while `config/.env`
and `certs/server.key` still reach the context and can land in an image layer
— which is more dangerous than a short file with no secret patterns at all,
because it reads as solved and stops anyone looking. Give every
depth-independent pattern the `**/` prefix and leave only genuinely
root-anchored entries unprefixed: `.claude`, and the repo's own host-built
binary, written `/myapp` and never `**/myapp`, which would also match
`cmd/myapp/` and delete the package directory from the context. Matching is
case-sensitive, and an ALL-CAPS twin per pattern still misses `Server.Key`, so
secret names use character ranges — `**/*.[kK][eE][yY]`, `**/*.[pP][eE][mM]`,
and likewise for `.envrc` and the extensionless SSH keys. Where such a pattern
also catches something the build needs, re-include it with a negation
(`!docs/example.env`); deleting the pattern reopens the exposure for every
other file it covers. Fetch the standard `.dockerignore` from
`https://git.eeqj.de/sneak/prompts/raw/branch/main/.dockerignore` and extend
it with the repo's own artifacts.
- **In-repo agent scratch belongs in both files, written to each file's own
semantics.** `.claude/` holds one worktree per in-flight agent — an entire
additional checkout of the repo — so under `COPY . .` the build context
inflates by a multiple of the repo and another session's unreviewed work can
be copied into an image layer. In `.gitignore` the entry is `.claude/`,
unanchored. In `.dockerignore` it is `.claude`, anchored and with **no** `**/`
prefix, because the prefixed form would also delete any nested directory of
that name from the build. Anchoring carries a known gap that the canonical
`.dockerignore` states in its own comment, since consuming repos receive the
file and not the tracker: the directory is created in the agent's working
directory, so a repo running agents in subdirectories still ships
`services/api/.claude/` and must add its own anchored entry there.
- **A plain `docker build .` of a clone stamps the version that
`git describe --tags --always` gives**, derived from the `.git` in the build
context as the canonical `Dockerfile` above shows. Without its failure check,
a missing `git` or an unreadable checkout would leave `-X main.Version=` empty
and the build would still exit 0. `script/docker` and `script/cibuild` pass
the version they compute on the host; it takes precedence. They do this
byte-identically across repos:
```sh
# Own line: a failing command substitution inside an argument does not
# trip `set -e`, so the inline form degrades to an empty constant.
version="$(git describe --tags --always --dirty 2>/dev/null || true)"
[ -n "$version" ] || version="unknown"
docker build --no-cache \
--build-arg VERSION="$version" \
-t "$(script/projectname)" .
```
`--always` makes an untagged repo yield an abbreviated commit hash rather
than failing, and the `[ -n "$version" ]` line is the single place the
fallback is applied — a live check that fires on a build from an export with
no `.git` and on a repository with no commits yet. Do not fold it into the
substitution as `|| echo unknown`, which makes the guard unreachable. The
Dockerfile's side is `ARG VERSION` in the stage that compiles, declared
there because `ARG` is stage-scoped; passing `VERSION` to a repo whose
Dockerfile declares no such `ARG` is ignored and costs nothing, which is why
the scripts stay byte-identical. One consequence for CI: the standard
checkout action clones shallow and fetches no tags, so a repo that embeds a
tag-derived version must set `fetch-depth: 0` on its checkout step.

canonical, which only the user merges. One list is exempt from byte-identity,
because it cannot be written once for every repo: the `deny` list of the
`test-support` depguard rule, where a repo names its own test-support packages
by full import path. A repo adds entries there and changes nothing else, and a
re-vendor carries its entries forward. The canonical golangci-lint version is
v2.14.0 (released 2026-09-24), pinned as the digest of the lint phase's base
image
(`golangci/golangci-lint@sha256:ad862ba6b3798cbe0fd9fd7408d498fd74fbd2623a92406b2fd3898faf0bf98f`,
which reports `2.14.0 built with go1.27.0 from 114493f9`). A module's `go`
directive must not name a newer Go minor version than the one golangci-lint
was built with, or golangci-lint refuses to lint it: this release lints
`go 1.27.1` but not `go 1.28`. That digest is the only pin, since no repo
installs golangci-lint on the host. A repo sets the lint phase digest to the
one named here and re-vendors `.golangci.yml` in the same commit, whichever of
the two prompted the change: the canonical copy can name linters that an older
golangci-lint rejects, and a newer golangci-lint can add linters that
`default: all` switches on until the canonical copy disables them.
- **`script/bootstrap` installs a pinned tool by comparing versions, never by
testing presence.** An `if ! command -v <tool>; then install; fi` guard tests
`PATH` only, so on an already-provisioned machine the pin is inert and a
version bump is a silent no-op — while the Dockerfile, installing into a clean
image, gets the pinned version, so a local `make check` and `make docker` can
disagree about what the tool even is. The canonical form:
- compares the installed version against the pin over the **whole** version
token; a parser that stops at the first `-` reports `2.12.2` for a host
running `2.12.2-rc1` and skips the install;
- treats absent, non-zero, empty or unrecognised `--version` output as a
mismatch, so the failure direction is a redundant install and never a
skipped one;
- after installing, re-resolves the binary the way callers do — `hash -r`,
then through `PATH`, not through the directory the installer wrote to —
and fails naming the resolved path, since an install that a shadowing
binary hides succeeds while changing nothing any caller sees;
- is actually called, and prints the version on both success paths: a
function defined and never invoked has the same exit status and the same
empty output as one that worked.
Keep it POSIX sh: no arrays, no `[[`, no `grep -P`.
A Go tool a repo needs on the host is installed with `go install` pinned to
a commit hash (`go install <package>@<commit hash>`). It is never tracked as
a `go.mod` tool dependency or through a `tools.go` file, either of which
pulls the tool's own dependencies into the repo's `go.mod` and `go.sum`.

# Completed Steps
- 2026-10-07: The part of `github.com/tyler-smith/go-bip39` v1.1.0 that `secret`
uses is copied into `internal/bip39`, with upstream's `LICENSE` beside it,
because its repository no longer exists
(https://git.eeqj.de/sneak/secret/issues/122). Every import moved there, and
the module left `go.mod` and `go.sum`. No derived key or mnemonic changes.
- 2026-10-07: The canonical files are re-vendored from `sneak/prompts` commit
`dd4027b` (https://git.eeqj.de/sneak/secret/issues/121), with golangci-lint
v2.14.0 in the lint phase. Lint and test are phases of the `Dockerfile`, and
`script/lint` and `script/test` each build one with `--no-cache`;
`Dockerfile.lint` and `script/lint-darwin` are gone, and the lint phase runs
`go vet` and checks the macOS build too. The tests run on the Debian Go image
with cgo and the race detector, with the policy's 90-second timeout.
`script/cibuild` bootstraps, runs `script/check` and builds the image;
`CHECK_EPOCH` and the memlock ulimit are gone. `--no-cache` starts Go's build
cache mount empty, so `make test` compiles everything on every run. The rules
in `CLAUDE.md` that `AGENTS.md` lacked are in `AGENTS.md`, and `CLAUDE.md` is
deleted.
- 2026-10-06: `script/test` runs the tests with the race detector, a 30-second
timeout per package and coverage, as `REPO_POLICIES.md` requires
(https://git.eeqj.de/sneak/secret/issues/32). When they fail, it reruns them
verbosely for the details and then fails anyway, so a test that fails once and
passes on the retry no longer gives a green build. `go vet` still runs first,
and every `go test` keeps `-count=1`. The tests that gave the `secret` binary
a minute now give it 10 seconds, and the PGP unlocker test's 30-second timer
is 10 seconds, so a test that hangs fails with its own message before the
package's 30-second timeout ends every test in it.
- 2026-10-06: `make test` in `script/cibuild` no longer compiles the standard
library and every dependency from nothing on every build
(https://git.eeqj.de/sneak/secret/issues/124). The `Dockerfile` runs it and
`make build` with Go's build cache in a BuildKit cache mount, which docker
keeps between builds, so each compiles only what changed since the last build.
The mount has an id of its own, so other repositories' builds do not share it.
`script/test` passes `-count=1`, so every test runs on every build and no
result comes from Go's test cache. A build with an empty cache, such as the
first after docker's build cache is cleared, compiles everything in
`make test` as before.
- 2026-10-06: `TestRemoveIgnoresTerminalOnStdout` and
`TestRemoveAsksAtTerminalOnStdin` no longer wait until Go's test timeout
(https://git.eeqj.de/sneak/secret/issues/126). On Linux, `pty.Open` of
`github.com/creack/pty` v1.1.24 passed the address of a local variable to the
`ioctl` system call as a plain number, through a function call; when Go moved
the goroutine's stack in between, the kernel wrote the terminal's number to
the old place, and `pty.Open` opened `/dev/pts/0` instead of the terminal it
had created. `secret rm` then wrote to that other terminal, and the test read
a terminal no program had open, which never ends. `go.mod` now requires the
commit on that library's main branch that passes a pointer instead; no release
has it yet. Both tests stop reading the terminal when their one-minute context
ends and fail saying so.
- 2026-10-06: The tests run quickly with the race detector on
(https://git.eeqj.de/sneak/secret/issues/120). Most of their time went to
deriving keys from passphrases with scrypt, which is slow on purpose. The new
`secret.ScryptWorkFactor`, when not zero, replaces age's scrypt work factor
when a passphrase encrypts; the tests of `internal/secret`, `internal/vault`
and `internal/cli` set it to 1 before any test runs, and the program never
sets it; `TestGetCommandOutputsToStdout` checks that the passphrase unlocker
the built binary's `secret init` writes names age's work factor, 18.
`TestRemovalAsksWithoutHoldingLock` and `TestFailedCommandReleasesLock` no
longer run in parallel with other tests: each waits at most 10 seconds for the
in-memory lock that every test in the package shares, and other tests'
commands held it longer. `TestConcurrentAddsKeepEveryVersion`, which times
nothing, and `TestGetCommandOutputsToStdout`, which no longer sets an
environment variable its commands do not read, now run in parallel. The
`script/cibuild` comment no longer says that tests are skipped without its
memlock ulimit.
- 2026-10-05: No test stores a secret larger than 1 MiB
(https://git.eeqj.de/sneak/secret/issues/52). The size tests for `secret add`,
`secret import` and the stdin buffer no longer try 2 MB, 10 MB, 99 MB, 100 MB
or 101 MB secrets, and nothing tests that a secret over the 100 MB limit is
rejected; the limit itself is unchanged. With nothing large left, the size
tests no longer skip a case for want of locked memory.
- 2026-10-05: The Go module path is `sneak.berlin/go/secret`, as
`REPO_POLICIES.md` requires, not `git.eeqj.de/sneak/secret`
(https://git.eeqj.de/sneak/secret/issues/43). Every import uses it, as do the
`-X` flags in `script/build` that stamp the version and commit shown by
`secret info`, and the examples in `pkg/agehd/README.md` and
`pkg/bip85/README.md`. `go mod tidy` now lists `github.com/dustin/go-humanize`
and `github.com/fatih/color`, which `internal/cli` imports, as direct
requirements. Code that imported the old path must switch to the new one.
- 2026-10-04: `make fmt` formats every markdown file with prettier (4-space
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.
- 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
(`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.

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.
`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.
(https://git.eeqj.de/sneak/secret/issues/88). `CreatePGPUnlocker` gets

`.`, `-` 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.
`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

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

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.
- 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
`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

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.

`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:
- 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;
- data under a `.tmp-` name in the state directory: a secret,
version or unlocker 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`.

`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.

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).
- 2025-05-28: Initial implementation (vault, age encryption, mnemonic,
CLI).
# Future Steps
- 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).
- CI does not compile, lint or test the files built only with cgo on macOS,
since compiling them needs Apple's SDK:
`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).
- CI does not compile, lint or test the files built only with cgo on
macOS, since compiling them needs Apple's SDK:
`internal/secret/keychainunlocker_cgo.go` (the three functions that call
`go-keychain`) with `keychainunlocker_test.go`, and `internal/macse`
(`macse_darwin.go`, `macse_test.go`, the Objective-C sources). Lint has never
run on them, so it would likely find more there than the line lengths. No
macOS test runs in CI. A macOS runner would cover all of it (asked on
https://git.eeqj.de/sneak/secret/issues/50).

never run on them, so it would likely find more there than the line
lengths. No macOS test runs in CI. A macOS runner would cover all of it
(asked on https://git.eeqj.de/sneak/secret/issues/50).
- 1.0 critical security blockers (from repo TODO.md):
- Memory security: age writes an identity's private key out as a string in
ordinary memory, and the copies it makes on the way stay there
(`secret.IdentityToLockedBuffer` overwrites only the string itself).
- Memory security: age identity .String() creates unprotected copies of
private keys; the call sites are listed in
https://git.eeqj.de/sneak/secret/issues/38.
- Medium priority:
- Standardize error messages; stop leaking internals.
- Graceful handling of corrupted or missing key files with recovery
suggestions.
- Split oversized CLI functions.
- Cleanups: read statedir from environment or default instead of passing it
around.
- Cleanups: read statedir from environment or default instead of
passing it around.
- Enhancements: help examples, 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
