Test Coverage Requirements — LNVPS Additions

See docs/agents-common/coverage.md for the base rules.

LNVPS-Specific Overrides

Generate the coverage report:

cargo llvm-cov --summary-only -- --test-threads=1

For a line-level breakdown, open the HTML report:

cargo llvm-cov --open -- --test-threads=1

Interpreting the report:

  • The terminal summary shows per-file Fns %. A file you touched must reach 100% for functions you added.
  • The HTML report highlights uncovered lines in red.
  • Functions that are #[cfg(test)]-only or compile-time-only (e.g. derive impls) are excluded automatically.

Checklist additions:

  • cargo llvm-cov --summary-only -- --test-threads=1 shows 100% function coverage for every file you modified
  • cargo test -- --test-threads=1 passes with no failures (see build-and-test.md)
