On an unchanged tree docker served every check step of the Dockerfile
from its build cache, so a second script/cibuild ran no lint, tests or
build and still succeeded.
script/cibuild now passes the current time as the CHECK_EPOCH build
argument. The lint and build stages each declare it after their module
download and before `COPY . .`. A build argument whose value changes
makes every RUN step after its declaration miss the cache, so the
checks run on each build while the base images, the apk install and the
module downloads stay cached.
Model: opus-5-5
script/lint builds the new Dockerfile.lint, where golangci-lint runs as
a build step. The lint stage is rebuilt on every run, so an unchanged
tree is linted too; the module download stays cached. script/bootstrap
no longer installs golangci-lint. The Dockerfile lint stage calls
golangci-lint directly, since make lint now starts a docker build.
golangci-lint config verify is not run: it fetches its schema live over
unpinned HTTPS.
Model: opus-5-5
The size tests skip a case whose secret needs more locked memory than
the process can lock, found by locking a buffer of that size: memguard
panics otherwise, and a plain `docker build .` runs under an 8 MiB
RLIMIT_MEMLOCK. script/cibuild, or any process allowed to lock past the
limit, runs every case.
The build stage stamps the VERSION build argument, else
`git describe --tags --always`, and fails when .git is present but
yields no version. `make build` stamps `git describe` too instead of
the fixed 0.1.0. .dockerignore keeps .git/config out; script/docker is
now the canonical copy.

Bumps golangci-lint from v2.1.6 (digest-only pin in the `Dockerfile` lint stage) to v2.12.2, pinned by tag and digest (Debian-based image).
Replaces `.golangci.yml` with the canonical strict config: all linters enabled except the standard disable list (`exhaustruct`, `depguard`, `godot`, `wsl`, `wrapcheck`, `varnamelen`), `lll` at 88, `funlen` 80/50, `cyclop` 15, `dupl` 100, and test files are now linted (the old config had `tests: false`, an enable-only list of ~20 linters, `lll` 120, and a blanket exclusion of `internal/macse`).
The stricter config surfaced ~1550 findings, all fixed:
- `wsl_v5` (439) / `nlreturn` (24): blank-line insertions
- `lll` (309): line wrapping at 88 columns; long literals split with `+` concatenation, values unchanged
- `noinlineerr` (130): `if err := ...` split into assignment plus check
- `paralleltest` (116): `t.Parallel()` added to tests without shared state; reasoned `//nolint` where `t.Setenv` or shared fixtures forbid it
- `err113` (97): package-level sentinel errors (new `internal/vault/errors.go`), `%w` wrapping, `errors.Is`
- `perfsprint` (74) / `modernize` (39) / `intrange`: `strconv`, `errors.New`, `slices.Contains`, `any`, `SplitSeq`
- `goconst` (40) / `dupword` (41) / `testifylint` (42) / `thelper` (33): constants, assertion fixes, `t.Helper()`
- `noctx` (22): `exec.CommandContext` for gpg/CLI invocations
- `testpackage` (18): black-box tests moved to `_test` packages where they use only exported identifiers; white-box files carry a reasoned `//nolint`
- `funlen`/`cyclop`/`gocognit`/`nestif`/`dupl`: behavior-preserving helper extraction
- assorted singletons: `gosec`, `gosmopolitan`, `funcorder`, `nonamedreturns`, `makezero`, `prealloc`, `godox`, `nolintlint`, `ireturn`, `nilnil`, `gochecknoinits`
## User-visible strings
**None changed.** Every error message this branch composes is byte-identical to the one `main` composes.
The `err113` sentinels are shaped so `fmt.Errorf` reassembles the original text around them: the sentinel carries the fixed words and the caller supplies the interpolated value in the position it has always occupied. Where the value sits mid-sentence the sentinel holds only a fragment (e.g. `vault.ErrVaultNotFound` is `"does not exist"`, composed by its caller as `vault <name> does not exist`); each such sentinel documents the message it participates in.
Verified mechanically, not by inspection: every `fmt.Errorf` and `errors.New` call site in both trees is parsed, the `Error()` text of any sentinel passed to `%w` is substituted in, and the resulting sets of composed message templates are compared. All 350 templates `main` produces are still produced, character for character. The set of lost or altered messages is empty.
## `unlocker list`
`findUnlockerIDByMetadata` returns `(string, error)` rather than signalling failure with an empty ID, so an unreadable `unlockers.d` is no longer indistinguishable from "no matching entry". `UnlockersList` skips such an entry with a warning naming the directory — its behavior before the scan was extracted into a helper — instead of emitting a row under a synthesized fallback ID that no `unlocker remove` or `unlocker select` can match and that suppresses the current-unlocker marker. The duplicate-check and shell-completion callers skip on the same condition, matching their pre-extraction behavior. Covered by `internal/cli/unlockers_list_test.go`.
`TODO.md` records the change plus follow-ups (version-completion TODOs formerly in code comments, darwin-gated files exceeding 88 columns that Linux CI does not lint).
`make check` is green and the pinned v2.12.2 image reports `0 issues.` Note the test suite needs the memlock ulimit from `script/cibuild` for the 10MB memguard test; that requirement is pre-existing.
Not changed: `script/bootstrap` installs golangci-lint via the system package manager (no version pin to bump), and `script/lint` invokes whatever `golangci-lint` is on PATH. golangci-lint v2.12 deprecates `gomodguard` in favor of `gomodguard_v2` (warning only); the canonical config owns that decision.

- Add DOCKER_HOST export to Makefile for remote Docker daemon
- Create multi-stage Dockerfile:
- Build stage: golang:1.24-alpine with gcc, make, git
- Runtime stage: alpine with ca-certificates, gnupg
- Runs as non-root 'secret' user
- Add Makefile targets:
- docker: build container as sneak/secret
- docker-run: run container interactively
- Add .dockerignore to exclude build artifacts but keep .git
for potential linker flags
Container includes GPG support for PGP unlockers and runs on Linux,
making it suitable for cross-platform testing and deployment.
