server.append()extends an existing SFRA route by adding middlewareafter the existing middleware chain. It does not replace or bypass the middleware already defined onHome-Show. Therefore, the consent-tracking middleware, cache middleware, and original route logic execute first; after they callnext(), the appended custom function executes.

Salesforce explicitly describesserver.appendas a customization mechanism that causes the original middleware chain to execute together with the additional appended step. It is commonly used when a cartridge must enrich an existing route without duplicating or replacing the base implementation.

The custom controller does not need to repeatconsentTracking.consentorcache.applyDefaultCachesimply because those functions are already part of the inherited route. Option B would become relevant if a middleware filtering condition itself rejected the request, but the absence of those declarations in the appended step does not inherently produce a parameter-mismatch error.

The resulting execution order is therefore: original middleware and base route logic, followed by the appended custom logic.
