sneak c5df0e3139 Record file mode in the manifest, 0000 unless asked (closes #161)
check / check (push) Waiting to run
Details 
MFFilePath gains mode (field 304): a file's permission bits, 0777 at
most, or 0000, meaning none recorded. gen and freshen record real modes
only with --include-permissions (ScannerOptions.IncludePermissions); the
builder keeps only mode.Perm(), so setuid, setgid and sticky are never
written. list -l and export show the mode in octal. check reports
MODE_MISMATCH for a recorded mode other than 0000 the file lacks. fetch
refuses a manifest with a mode above 0777 before requesting any file,
sets only the permission bits of each recorded mode on the files it
writes, and downloads again a present file whose mode differs. The decoding-cost bound counts a file
entry at 176 bytes, up from 160.

clawbot ce66f7c1c1 Re-vendor the canonical files from sneak/prompts dd4027b (closes #159, closes #116)
check / check (push) Failing after 7s
Details 
Fetches .dockerignore, .editorconfig, the CI workflow, .gitignore,
.golangci.yml, .prettierignore, .prettierrc and REPO_POLICIES.md byte
for byte from sneak/prompts dd4027b; this repo's own entries follow the
canonical text in .dockerignore, .gitignore and .editorconfig. The new
.golangci.yml disables gomodguard. The Dockerfile gets a lint phase on
golangci-lint v2.14.0 and a test phase on the Debian Go image; the
build stage depends on both and stamps the version as the policy shows.
script/test and script/lint build only their phase, and script/cibuild
bootstraps and runs script/check first. bin/tools goes: script/bootstrap
installs gofumpt and protoc-gen-go into bin/ with go install pinned to a
commit.

clawbot 343431dd30 Drop atime from the format spec and pin the file entry fields (closes #158)
check / check (push) Successful in 2m16s
Details 
atime left mf.proto earlier and nothing reads or writes it, but
docs/FORMAT.md still narrated its removal and listed it among the
determinism rules. The spec now describes the file entry by its fields
only.

A new test compares the MFFilePath message descriptor, by name and
number, with a list copied from the spec's field table. It does not read
the spec, so changing a field means changing the proto, the spec and
that list together.

clawbot 99b3e0e202 fetch refuses a manifest whose paths differ only in letter case (closes #154)
check / check (push) Failing after 2s
Details 
On a case-insensitive filesystem such paths are one name. Of two files,
one replaced the other and fetch exited 0. For a file and a directory
another file is in, fetch stopped partway with a non-zero exit, leaving
a partial tree. For two spellings of one directory, both files landed
in one directory, one under a spelling the manifest does not list, and
check reported that file as not in the manifest.

The existing name-clash check now also records each listed file and
each directory one is in. A listed file at a name already taken, or a
directory spelled differently from one already there, is refused on
every filesystem, before the destination is created. The message names
both paths.

clawbot ce024baaed Move the CLI to urfave/cli v3 (closes #110)
check / check (push) Failing after 3s
Details 
Ported per the library's v2-to-v3 migration guide: the app is a root
cli.Command, actions take a context and the command, and flag
environment variables become value sources. -v, -q and the version flag
are local so, as before, only the commands defining them accept them.
Every command stops reading flags at its first argument, as v2 did.
ErrWriter is stdout so usage errors print with their help. The action's
context reaches the manifest download in check, export and list.
testify rises to v1.12.1, which v3 requires; the urfave_cli_no_docs
build tag, which v3 lacks, is dropped. v3 accepts a flag given under two
names, so -v --verbose gives debug output, and the test pinning the
refusal becomes a TestVerboseCount case.

clawbot ab72692439 Pin the remaining developer tool installs (closes #68)
check / check (push) Failing after 3s
Details 
gofumpt and protoc-gen-go are tools of a separate Go module in bin/tools,
so `go tool` builds them from source checked against bin/tools/go.sum and
mfer's own module gains no dependencies. script/bootstrap downloads that
module, and unpacks protoc 33.4 into bin/protoc from its release archive
after checking the sha256 it holds for the platform. script/generate runs
that protoc with the pinned plugin, so mfer/mf.go and its go:generate line
go. script/prettier runs only the node_modules prettier, fails when it
differs from the package.json pin, finds the node bootstrap installed
through nvm by the version in .nvmrc, and runs prettier once. Comment and
package.json fixes.

clawbot 9bb0ab3a03 fetch refuses a manifest that lists another file's temp name (closes #151)
check / check (push) Failing after 2s
Details 
fetch downloads each file to a temp name beside it and first removes
whatever is there. A manifest listing both a.txt and .a.txt.tmp had
fetch delete the second while fetching the first, then exit 0 with a
tree check rejects.

The refusal of a manifest that lists the saved manifest's own name or
temp name now covers this too: a listed file, or a directory a listed
file is in, may not sit at any name fetch writes besides the listed
files themselves. Temp names come from tempPathFor, names are compared
ignoring case as before, and the refusal still happens before the
destination is created or any file requested.

clawbot d3394bd2a2 Makefile: thin shims only, add make build (closes #73)
check / check (push) Failing after 2s
Details 
The Makefile is now one shim per script/ entrypoint, in the order of
the canonical model Makefile, plus build, generate and fuzz. The new
script/build writes bin/mfer with the urfave_cli_no_docs tag and the
git describe revision that script/docker stamps. script/generate now
adds the Go bin directory to PATH itself, and the Docker lint stage
calls script/gofumpt --check directly. Removed: the tarball-caching
rules and their ignore entries, godoc, ci, fixme, clean, run, default,
fmt-check-go, fmt-check-md, and bin/gitrev.sh, which only the
Makefile called.

clawbot a3e37d1ab8 fetch: destination directory, skip files already present, save the manifest, require a signer (closes #101)
check / check (push) Failing after 3s
Details 
fetch takes --dest (default .) and writes every file there through the
existing symlink and hard-link guards, which now work relative to that
directory. A file already there with the listed size and hash is
skipped; a leftover temp file is still replaced. Once every file
verifies, the manifest is saved as index.mf through the same temp file
and rename, so check runs on the result; a manifest that lists index.mf
or its temp name at the top of the tree is refused, since saving would
replace that file. --require-signature is shared with check and
enforced through verifyRequiredSigner. Both refusals come before any
file is downloaded or anything is written.

clawbot acff23d92b Check Go formatting with gofumpt, as make fmt writes it (closes #70)
check / check (push) Failing after 2s
Details 
The Go format check ran plain gofmt, which accepts code that gofumpt,
the formatter script/fmt runs, rewrites; and the two covered different
files. Both now go through script/gofumpt, which runs one pinned
gofumpt version over every Go file in --write or --check mode, as
script/prettier does for Markdown. It replaces script/fmt-check-go;
make fmt-check-go and the Docker lint stage call it. go run builds the
pinned version, so nothing has to install gofumpt, and the check fails
when gofumpt cannot run instead of passing. Generated mfer/mf.pb.go
passes: gofumpt holds generated files to gofmt's rules. The check is
not redundant: .golangci.yml enables no golangci-lint formatters.

clawbot 8fe0244291 check always warns about files the manifest does not list (closes #103)
check / check (push) Failing after 2s
Details 
check now always looks under the base directory for files the manifest
does not list, hidden files and directories included, and prints one
warning per file. The result still depends only on the listed files;
--no-extra-files turns each unlisted file into a failure, and --quiet
hides the warnings but not the failures. A directory that cannot be
listed is reported the same way, and the search goes on past it.

The manifest itself is left out by file identity, as gen and freshen
do; a symlink under the base is compared by what it points to. A base
directory named through a symlink is resolved before the search.

clawbot 400a2f8f63 Move FORMAT.md to docs/ and contrib/ to bin/, fix bash script style (closes #74)
check / check (push) Failing after 3s
Details 
FORMAT.md moves to docs/ and every reference follows; its two relative
links to mfer/mf.proto now point up one directory, its text is otherwise
unchanged. contrib/usage.sh moves to bin/, not docs/: it is a script you
run (it builds mfer, then generates and checks a manifest of the repo),
not reading material. Both scripts now use #!/usr/bin/env bash,
set -euo pipefail and a main function. bin/gitrev.sh still exits non-zero
outside a git checkout, so the Makefile still falls back to unknown.
.gitignore now ignores only the built bin/mfer rather than all of bin/,
which holds tracked scripts.

clawbot ba3d24ca42 End-to-end tests for freshen and fetch (closes #66)
check / check (push) Failing after 3s
Details 
The freshen tests built a fixture and never ran freshen. They now run
gen and freshen through the command entry point on a temp dir: an
unchanged tree leaves the manifest's entries as they were, and a
modified file (also one edited without changing its size), a new or a
deleted file gives a manifest that lists exactly the tree, with sizes,
hashes and mtimes from disk, on which check passes.

New fetch tests run the command against an httptest server: a nested
tree lands complete, a hash mismatch exits non-zero and leaves no file,
and a partly filled destination gets every listed file downloaded again
and replaced, while a file the manifest does not list is left alone.

clawbot 11041330a7 Move internal/log from apex/log to log/slog (closes #77)
check / check (push) Failing after 2s
Details 
internal/log now logs through log/slog. After Init, records go to a small
slog.Handler that prints the same lines as before; before Init they go to
slog.Default(). The helpers and their call sites are unchanged. With
NO_COLOR set on a terminal, log lines are no longer colored.

pterm is dropped: it only printed progress lines, which fmt now writes
directly, outside slog. apex/log, pterm and their indirect dependencies
leave go.mod; golang.org/x/term becomes direct.

simplelog is not imported: importing it replaces slog's default handler in
every program that imports package mfer. The logger stays process-global,
since injecting it would change package mfer's API.

Progress and log lines now share the logger's lock, so the check progress
test runs check ten times to catch a missing wait.

clawbot 5c7ef94799 Set go_package to the sneak.berlin/go/mfer module path (closes #79)
check / check (push) Failing after 1s
Details 
mf.proto named git.eeqj.de/sneak/mfer/mfer as its Go package, which
disagrees with the sneak.berlin/go/mfer module path go.mod declares.
go_package is now sneak.berlin/go/mfer/mfer, the import path of the
mfer/ package. mf.pb.go is regenerated with make generate, which
changes only the go_package bytes in its embedded descriptor, and
mf.proto.sha256 records the new mf.proto hash.

clawbot 82b9434444 fetch: client timeout, retry with backoff, url.JoinPath (closes #63)
check / check (push) Failing after 2s
Details 
fetch now makes every request through an http.Client with a time
limit, ten minutes by default and set with --timeout, which must be
greater than zero. A connection error, a timeout, or a 5xx or 429
response is retried, up to five tries in all, after a random wait
whose limit doubles from one second, or after the wait the server's
Retry-After asks for, up to one minute. Each try of a file starts a
new temp file, so a retry never keeps a partial file; the size and
hash checks are unchanged. Manifest and file URLs are built with
URL.JoinPath, so trailing slashes, query strings and names that need
escaping all work.

clawbot 6a2307a82b check waits for its progress output before the summary (closes #140)
check / check (push) Failing after 1s
Details 
With --progress, runCheck started the progress goroutine but waited
only for the results goroutine, so check could log its summary, or
return, before the last progress line was written and cleared. The
progress goroutine now signals a sync.WaitGroup when it finishes, and
runCheck waits on it as soon as Check returns, as generate does.

The new test sends stdout and stderr to one buffer and slows down
stdout writes, so without the wait the progress output lands after
the summary.

clawbot 4bf87d1ccf AddFileWithHash rejects hashes that are not multihashes (closes #129)
check / check (push) Failing after 2s
Details 
AddFileWithHash took any non-empty bytes as a hash, so the builder could
write a manifest that mfer refuses to load. It now decodes the hash with
go-multihash and also requires a digest of at least 32 bytes, the SHA-256
length the reader's decoding-cost limit assumes: a valid but shorter
multihash, such as an empty identity hash or SHA-1, still makes a
manifest of one-character paths too costly to load. When mfer freshen
meets such a hash in an existing manifest, its error names the manifest
entry and says to regenerate the manifest with mfer generate. Test
fixtures whose stand-in hashes were not valid multihashes now use a
SHA-256 multihash.

clawbot e412d20c20 Default the manifest to index.mf and keep it out of its own listing (closes #100)
check / check (push) Failing after 1s
Details 
mfer gen now writes index.mf instead of .index.mf, the name fetch
requests and the README calls the standard filename. Given a
directory, check, freshen, list and export look only for index.mf;
.index.mf is no longer recognized. Because index.mf is not hidden, gen
and freshen leave out of their own listing the manifest they write and
a temp file an interrupted run left beside it, matched by file
identity (os.SameFile) however the path is spelled. The scanner takes
these as a plain ExcludePaths list; manifestTempPath alone names the
temp file, for both writes, both skips and the tests.

clawbot 0501568203 Never regenerate mf.pb.go during checks; fail when it is stale (closes #71)
check / check (push) Failing after 1s
Details 
The test and format scripts regenerated mfer/mf.pb.go whenever
mfer/mf.proto looked newer by mtime, which a fresh checkout often causes,
so make check could rewrite a committed file and needed protoc. Nothing
regenerates it any more except make generate (script/generate), which
refuses to run unless protoc 33.4 and protoc-gen-go v1.36.11, the
versions that wrote the committed file, are on PATH, and records the
hash of mf.proto in mfer/mf.proto.sha256. A Go test compares that hash
with mf.proto and fails, naming make generate, when they differ. The
mtime rule, the unused protoc-gen-go v1.28.1 install rule, make clean's
deletion of mf.pb.go and the Dockerfile's touch workarounds are removed.

clawbot 0a9963002c NewChecker takes CheckerOptions instead of positional arguments (closes #78)
check / check (push) Failing after 1s
Details 
NewChecker now takes *CheckerOptions (ManifestPath, BasePath, Fs), named
like ScannerOptions. A nil Fs still means the OS filesystem, as before and
as in ScannerOptions; nil options or an empty path return an error naming
the missing path.

Audit of the other exported constructors in mfer: NewManifestFromFile took
a filesystem and a path positionally; it now takes
*ManifestFromFileOptions (Path, Fs) with the same nil and empty rules.
NewBuilder and NewScanner take no arguments, NewScannerWithOptions already
takes options, and NewManifestFromReader takes one reader, which the style
guide exempts; these are unchanged.

clawbot 76116005c8 Reject manifests whose file entries decode far larger than their bytes (closes #123)
check / check (push) Failing after 2s
Details 
Before decoding the manifest, the parser adds up what decoding sets
aside for each file entry, hash, timestamp and MIME type, however short
its encoding, and refuses the manifest once that passes 8 times the
decompressed size; manifests mfer writes come to at most about 7.15
times. Empty entries decoded to about 50 times their size: under 1 KB of
manifest allocated about 500 MB. Fields the decoder does not know are
dropped; kept, they took up to 5 times more. A test refuses entries
counted just over 8 times and loads them just under. The fuzz ceiling
rises from 16 to 20 times the input and decompressed data; seeds of
empty entries and of empty hashes fail it without the fix.

`mfer/mf.proto` and record the hash of that `mfer/mf.proto` in
`mfer/mf.proto.sha256`; the only thing that regenerates the committed
`mfer/mf.pb.go`. It runs the `protoc` that `script/bootstrap` unpacks into

size, hash and recorded mode the manifest lists is skipped. Once every
file is in place, the manifest is saved there as `index.mf`, so
`mfer check` can verify the tree later. Each file is downloaded to a temp
file beside it, such as `.a.txt.tmp` for `a.txt`, given the mode the
manifest records unless that is `0000`, then moved into place. A manifest
is refused before any file is downloaded if it records a mode above
`0777`, or lists a file where fetch writes another: at another listed file
or a directory one is in, at the temp file of a listed file, or at
`index.mf` or `.index.mf.tmp` at the top of the tree. Names are compared
in any letter case, on every filesystem, since on a case-insensitive one
`A.txt` and `a.txt` are one file; a directory two listed files are in must
be spelled alike in both.

fingerprint, as `mfer check --require-signature` does, before downloading

`script/precommit`, not in the hook itself. Model scripts are at
repo root, runs `script/bootstrap`, runs `script/check`, and builds the image
with the version; the Gitea workflow calls it. **`script/cibuild` runs
`script/bootstrap` first**, because the workflow checks out the repo and runs
nothing else, while `script/fmt-check` runs the formatter on the host: on a
pristine checkout with nothing installed the run dies there, after the
containerised gates have passed. **The bootstrap alone is not enough**:
`script/bootstrap` installs node and yarn under nvm and leaves neither on the
`PATH` of the shell that called it, so a bare `yarn` still exits 127. The host
entrypoints that need yarn — `script/fmt` and `script/fmt-check` — therefore
source nvm for the pinned node version before invoking it, exactly as
`script/bootstrap`'s own install step does. A runner carrying nothing but
docker and git then gets through `script/check`. Four further scripts are our

contributor should be able to understand the entire development workflow by
reading the Makefile.
- 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.
- 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.
- **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.
- **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:
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,
and the test phase is based on the Debian Go image. The canonical Go repo

Key points:
- 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.
- 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.
- If the project uses `//go:embed` directives that reference build artifacts
(e.g. a web frontend compiled in a separate stage), the lint stage must
(e.g. a web frontend compiled in a separate stage), the lint phase must
create placeholder files so the embed directives resolve. Example:
`RUN mkdir -p web/dist && touch web/dist/index.html web/dist/style.css`.
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.
- 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.
- Every repo should have a Gitea Actions workflow (`.gitea/workflows/`) that
runs `script/cibuild` (which runs `docker build .`) on push. Since the
Dockerfile already runs `make check`, a successful build implies all checks
pass.
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
tests. It leaves the build cache alone, so it costs the runtime of the suite
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
test, so there is nothing to replay. `--no-cache` (above) is what makes that

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.
- **Verify `.dockerignore` by enumerating the image, not by reading the
patterns.** Plant files at the root _and_ at least two directories deep, build
a probe image that does `COPY . .`, and list what actually landed
(`docker run --rm --entrypoint find IMAGE /app`). The `transferring context`
size is not a substitute: a nested secret is a few bytes, and BuildKit
transfers only the delta from the previous build.

`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

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;
