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).

# Local equivalent of the weekly coverage workflow (.github/workflows/coverage.yml,
|
|
# backlog#1153 infra-5): same measurement scope (--workspace --exclude e2e_test,
|
|
# nextest `ci` profile) and the same per-crate table. Slow — the instrumented
|
|
# build cannot reuse your normal target cache and then runs the whole suite.
|
|
# Doctests are not measured (needs nightly). Outputs land in target/llvm-cov/.
