actions/checkout writes its token into .git/config as an http extraheader,
where it stays for the rest of the job. That matters more here than usual:
pull_request jobs run on self-hosted runners and execute the PR's own build.rs,
proc-macros and tests, any of which can read that file. Test and Lint holds
actions: write on top of that, so its token can cancel runs and delete the
Actions caches the whole pipeline now depends on — it was given
persist-credentials: false when that permission was added, and this extends the
same treatment to the other 45 checkouts.
Two are exempt because the token IS the credential the job needs.
helm-package's publish job pushes to rustfs/helm with it; clearing it would
break chart publishing. nix-flake-update is exempt pending verification: it
passes FLAKE_UPDATE_TOKEN to create-pull-request directly rather than reusing
.git/config, so it very likely does not need persistence, but that is unproven
and a broken weekly bot is not worth the guess. Both carry a
persist-credentials-exempt comment saying which.
scripts/security/check_persist_credentials.sh requires every checkout to either
clear its credentials or carry that comment, so the decision stays visible in
review rather than being an omission nobody notices.

Two cleanups, neither changing what is built or published.
docker.yml loses its type=gha layer cache. The image build compiles nothing —
it downloads a release zip and runs apk/apt — so the cache could only save the
minute or two those take, against a real correctness problem: with
RELEASE=latest the binary URL is resolved by curl inside a RUN layer, and the
layer key does not include what it resolved to. A rebuild at the same RELEASE
value (a dispatch with version=latest, or a re-run of the same version) would
hit the old layer and ship the previous release's binary. mode=max also drew on
the same repo-wide 10GB Actions cache quota the Rust lanes are contending for.
Only RELEASE is passed as a build-arg now; it is the sole one the Dockerfiles
declare besides TARGETARCH. BUILDTIME, VERSION, BUILD_TYPE, REVISION and CHANNEL
were read by no stage, and BUILDTIME's $(date ...) was a literal string in the
YAML block rather than a substitution. The DOCKER_CHANNEL computation that fed
CHANNEL evaluated to "release" down every branch and is gone with it. BUILD_DATE
and VCS_REF stay unset even though the Dockerfiles declare them: supplying them
would change the published image labels.
The setup composite stops installing tools its callers do not use. protobuf-
compiler comes out of the apt list entirely — setup-protoc installs 34.1 into
the tool cache and prepends it to PATH, so the apt build was shadowed on every
run and never used; the same duplicate install is removed from the io_uring lane.
musl-tools, zip and unzip move behind install-build-packaging-tools, off for the
CI and coverage lanes and left on for build.yml, whose native musl leg needs
musl-gcc and whose packaging steps need zip. cargo-nextest and the
rustfmt/clippy components move behind install-test-tools, off only for build.yml,
which runs no tests and no lints; coverage and the nightly replication lane keep
them because both invoke nextest.
The action's github-token input is deleted along with its 20 call sites. Its
runs block never referenced it — setup-protoc uses github.token directly — so it
was 20 places handing a token to something that ignored it.

ci(coverage): weekly cargo-llvm-cov workspace baseline (non-blocking)
Add the weekly line-coverage report (backlog#1153 infra-5):
- .github/workflows/coverage.yml — Sunday 07:00 UTC + workflow_dispatch;
runs `cargo llvm-cov nextest --workspace --exclude e2e_test` under
NEXTEST_PROFILE=ci (same scope and profile as the ci.yml test gate),
writes a per-crate line-coverage table to the job summary, uploads
lcov + JSON as a 90-day artifact, and routes scheduled failures
through the shared schedule-failure-issue action (ci-8). Runs only on
schedule/dispatch, so it can never become a required PR check.
- scripts/coverage_per_crate.py — stdlib-only aggregation of the
llvm-cov JSON export into the per-crate markdown table (worst-first,
TOTAL row), shared by the workflow and the local target.
- make coverage (.config/make/coverage.mak) — local equivalent with the
same command sequence; fails with install hints when cargo-llvm-cov
or cargo-nextest are missing. Listed in make help.
- docs/testing/README.md — Coverage section: cadence, where the table
and artifacts live, the trend-comparison method, and what is not
measured (doctests, e2e_test).
