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 each build one phase by name with caching disabled, and the final stage copies a harmless file from each so the image cannot be built unless both passed — the ordering trick already in template-app-go's Dockerfile, extended to the test phase. A phase that is not the last stage is built only when something depends on it or --target names it, so the gates are always invoked by name and the edges are kept. Every build in script/ is tagged. No config verify step; fmt stays on the host. This closes issue 30 too: a container has its own result cache and lock. Model: opus-5

# script/lint: run the linter. Linting is a phase of the Dockerfile and
|
|
# this builds that phase alone; the linter is never installed or run on
|
|
# a developer host, where a shared result cache and a host-global lock
|
|
# make its answer untrustworthy.

|
|
# The phase is not the last stage in the file, so it is built only when
|
|
# --target names it. --no-cache because a cached lint layer is a lint
|
|
# that did not run. The tag makes each build replace the previous image
|
|
# instead of leaving a dangling one behind.
