Per the owner ruling on issue 40, linting and testing are phases of the
main Dockerfile rather than a separate lint file. script/lint and
script/test build one phase each by name with caching disabled, and the
final stage copies a harmless file from each so the image cannot be built
unless both passed. A stage that is not the last is built only when
something depends on it or --target names it, so the gates are invoked by
name and the edges kept. script/check runs the gates and builds no image
of its own; script/cibuild bootstraps first, because CI runs it alone and
fmt-check is native. fmt and fmt-check source nvm for the pinned node
before calling yarn, which bootstrap installs but leaves off its caller's
PATH. Every build in script/ is tagged and uncached. Issue 30 closes too:
a container has its own lint cache and lock.

The canonical .dockerignore and .gitignore both omitted the in-repo agent
scratch directory, which holds one worktree per in-flight agent, so under
`COPY . .` an entire extra checkout of the repo reached the image. The
two entries are deliberately different shapes: anchored in .dockerignore,
where the `**/` form would also delete a legitimately named nested
directory, and unanchored in .gitignore, where a pattern already matches
at every depth. Anchoring leaves a gap where agents run in
subdirectories, stated in the vendored file itself. The second half is
the consequence of excluding .git: `git describe` in a build stage yields
an empty version without erroring, so the version is now computed on the
host and passed in.
Model: opus-5
script/cibuild was a plain `docker build .` and the Dockerfile does
`COPY . .` followed by `RUN make check`, so on an unchanged tree Docker
served the check layer from cache: the suite never ran and the build
still exited 0. Measured here before the change, a second run on a
byte-identical tree returned in 0.286s with `RUN make check` CACHED.
script/cibuild and script/docker now pass --no-cache. The canonical text
asserting that a bare `docker build .` proves the checks ran was wrong in
REPO_POLICIES.md, both checklists and the Go styleguide, and is corrected
in all of them.
