Add the README's required sections and clear stale TODO.md items (closes #46 )

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. The README is rewrapped to prettier's settings. TODO.md: Next Step points at the 1.0.0 milestone, its four finished items move to Completed Steps with their dates, and Future Steps loses the items already done. Model: opus-5-5

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

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

    - `.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.

 - **`.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.

  by full import path. A repo adds entries there and changes nothing else, and a

  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

  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".

  (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
  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
