## —— Coverage --------------------------------------------------------------------------------------

# 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/.
