Linting and testing become the lint and test phases of the Dockerfile,
and the build stage depends on both. Dockerfile.lint, CHECK_EPOCH and
the tests that checked them are removed. Every docker build in script/
passes --no-cache, and script/cibuild runs script/bootstrap first. A
host without Go gets the go.mod version from script/install-go in
.tool/go, which bootstrap, the Makefile, fmt, fmt-check, precommit and
release add to PATH; fmt-check skips .tool. The image takes its version
from the VERSION build arg or git describe, dev without .git. This
repo's own entries follow the canonical content in .gitignore and
.editorconfig. The golangci-lint v2.14.0 findings are fixed. The rules
in CLAUDE.md move into AGENTS.md. IsDevVersion counts "unknown".
Model: opus-5-5
The release workflow installed Go with actions/setup-go, which pins the action but not the Go archive it downloads, so the compiler that builds the published binaries was verified against nothing in this repo.
New script/install-go, modelled on script/install-goreleaser, downloads the go.dev archive for the version in go.mod and refuses it unless its sha256 matches the value committed in the script. It fails if its version disagrees with go.mod, and on any OS or architecture other than the Linux release runners. GOTOOLCHAIN=local on the release step keeps the verified toolchain from switching itself.
Judgement call: release path only; script/bootstrap still uses the host Go.
