Changed-lines coverage summary
================================================================================
Denominator: lines added/modified by this PR in C/C++ source files that LCOV considers coverable (excludes blank lines, braces, comments, header-only declarations, and error-path noise such as `LOGICAL_ERROR`, `UNREACHABLE()`, `abort()`).
Numerator: of those coverable lines, the number actually executed by the test suite during this coverage run.
  PR changed C/C++ lines covered by tests: 94.80% (310/327)
