Seems to me that this is conceptually more a PrecacheManagerDelegate.

In this case, any reason for not declaring it in precache_manager.h? Just
curious.

Done.

+ public:
+  // Called when a new manifest is successfully fetched and parsed.
+  virtual void OnManifestFetched(const std::string& host,
+                                 const PrecacheManifest& manifest) = 0;
+};

+}  // namespace precache
