Copy go-bip39 into internal/bip39 (closes #122 )

go-bip39's repository no longer exists. The part of v1.1.0 that secret uses (NewEntropy, NewMnemonic, NewSeed, IsMnemonicValid and what they call; English word list only) now lives in internal/bip39 with upstream's LICENSE beside it, along with upstream's tests of that code and their vectors unchanged. Every import moves there, and the module leaves go.mod and go.sum. Beyond the trimming, only what the linter asked for changed. No derived key or mnemonic changes. Model: opus-5-5
Re-vendor the canonical files from sneak/prompts at dd4027b (closes #121 )

 # .dockerignore does NOT use .gitignore semantics. Docker matches with

 # .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.

 # 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.

  `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.
-    The standard pattern for a Go repo Dockerfile is:
+    ```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,

    - `.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.

  `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

 - **In-repo agent scratch belongs in both files, written to each file's own

  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

  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.

    `--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

  (`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

Author	SHA1	Message	Date
clawbot	ef0ae90768	Copy go-bip39 into internal/bip39 (closes #122 ) check / check (push) Waiting to run Details go-bip39's repository no longer exists. The part of v1.1.0 that secret uses (NewEntropy, NewMnemonic, NewSeed, IsMnemonicValid and what they call; English word list only) now lives in internal/bip39 with upstream's LICENSE beside it, along with upstream's tests of that code and their vectors unchanged. Every import moves there, and the module leaves go.mod and go.sum. Beyond the trimming, only what the linter asked for changed. No derived key or mnemonic changes. Model: opus-5-5	2026-10-07 12:56:10 +02:00
clawbot	2c6fe7c368	Re-vendor the canonical files from sneak/prompts at dd4027b (closes #121 ) check / check (push) Waiting to run Details The vendored files are copies from sneak/prompts dd4027b, with this repository's own entries after the canonical content. golangci-lint is v2.14.0. Lint and test are phases of the Dockerfile, which script/lint and script/test build with --no-cache; Dockerfile.lint and script/lint-darwin are gone, and the lint phase also checks the macOS build. The tests run on the Debian Go image with cgo and the race detector. script/cibuild bootstraps, runs script/check and builds the image; CHECK_EPOCH and the memlock ulimit are gone. Go's build cache stays in a cache mount, out of the test image's layer. Agent guidance lives in AGENTS.md alone; the tool-specific file is gone. Model: opus-5-5	2026-10-07 05:42:59 +02:00
clawbot	ed6af50ea5	Make script/test fail on flaky failures and enable -race (closes #32 ) check / check (push) Waiting to run Details script/test ended with a verbose rerun whose exit status became the script's, so a test that failed once and passed on the retry gave a green build. It now follows the REPO_POLICIES.md pattern: go vet, then go test -count=1 -timeout 30s -race -cover; on failure a verbose rerun for the details, then exit 1. -count=1 stays on both go test lines because the Dockerfile keeps Go's build cache between builds. The tests that gave the secret binary a minute, and the PGP unlocker test's 30-second timer, now use 10 seconds, so a hang fails with the test's own message before the package's 30-second timeout. The README describes the new run. Model: opus-5-5	2026-10-07 03:22:34 +02:00
clawbot	b109c4e5e1	Keep Go's build cache between builds (closes #124 ) check / check (push) Successful in 49s Details make test and make build in the Dockerfile now share one Go build cache, kept in a BuildKit cache mount with this repository's own id, so they compile only what changed. script/test passes -count=1. Model: opus-5-5	2026-10-07 01:02:35 +02:00
clawbot	ae030d759d	Stop the terminal tests reading a pty nobody opened (closes #126 ) check / check (push) Successful in 3m27s Details On Linux, pty.Open of github.com/creack/pty v1.1.24 passes the address of a local variable to ioctl as a plain number, through a function call. When Go moved the goroutine's stack in between, the kernel wrote the pty's number to the old place, and pty.Open opened /dev/pts/0, another terminal. secret rm wrote there, and the test read a terminal no program had open, which never ends. Require the commit on the library's main branch that passes a pointer; no release has it yet. Both terminal tests now stop reading when their one-minute context ends, and fail saying what was still waiting. Model: opus-5-5	2026-10-07 00:02:40 +02:00
clawbot	4ff0d20c10	Make the tests fast under the race detector (closes #120 ) check / check (push) Successful in 1m25s Details Deriving keys from passphrases with scrypt, slow on purpose, took most of the test time under -race. secret.ScryptWorkFactor, when not zero, replaces age's work factor when a passphrase encrypts; the tests of internal/secret, internal/vault and internal/cli set it to 1 in TestMain, and the program never sets it. TestGetCommandOutputsToStdout checks that the built binary's passphrase unlocker names age's 18. TestRemovalAsksWithoutHoldingLock and TestFailedCommandReleasesLock time the in-memory lock all tests share, so they no longer run in parallel. TestConcurrentAddsKeepEveryVersion and TestGetCommandOutputsToStdout time nothing and now do. The script/cibuild comment no longer says tests are skipped without its memlock ulimit.
