Type Alias RuntimeCoverageAnalyzer 

pub type RuntimeCoverageAnalyzer<'a> = dyn Fn(&RuntimeCoverageOptions, RuntimeCoverageSeamInput<'_>) -> Result<RuntimeCoverageReport, ExitCode> + 'a;

Runtime coverage analysis seam.

Runtime coverage execution drives the closed-source fallow-cov sidecar (license verification, subprocess spawning), which stays in the CLI. The engine calls this callback only when HealthExecutionOptions::runtime_coverage is set, so the default and programmatic paths never touch it.
