23/// Selects the concrete `SeverityInference` impl at compile time, milestone-gated by the
24/// `inference` Cargo feature (§17, §G.14): `NoInference` when the feature is off,
25/// `CommitInference` (a real git-backed adapter, §G.6.4) when it's on. `CommitInference`
26/// needs no workspace/runner context of its own -- `SeverityInference::infer` receives the
27/// caller's `GitAccess` per call -- so this needs no parameters and no lifetime.
