<purpose>Null deployment adapter — no-op DeploymentAdapter used for `adapter: "null"` registry entries (systems with no deployable runtime). Reports success for propagate/rollback, unknown health, and no capabilities.</purpose>

</MODULE_CONTRACT>
<CHANGE_SUMMARY>
  <item>REVIEW-CODE-2026-10-01-01: extracted from leitstand-commands.ts so the adapter registry can resolve names without importing the command module; carries bootSmokeCapable() → false (no runtime).</item>
