@spec apply_collection_response(struct(), String.t(), ExWapp.Binary.Node.t()) ::
  {:ok, non_neg_integer()} | {:error, term()}

Applies a collection response payload to the local store.

@spec apply_collection_response(
  struct(),
  String.t(),
  ExWapp.Binary.Node.t(),
  pid() | nil
) ::
  {:ok, non_neg_integer()} | {:error, term()}

Applies a collection response payload and optionally uses a live session when external blobs must be fetched while decoding snapshots or patch chains.

@spec apply_collection_response(
  struct(),
  String.t(),
  ExWapp.Binary.Node.t(),
  pid() | nil,
  keyword()
) ::
  {:ok, non_neg_integer()} | {:error, term()}

Applies a collection response using feature-specific persistence options.

The :max_records option is forwarded to call-log mutations.

@spec fetch_collection(GenServer.server(), struct(), String.t()) ::
  :ok | {:error, term()}

Fetches a single app-state collection and applies its snapshot and patches.

@spec send_mutation(GenServer.server(), patch_info(), struct()) ::
  {:ok, hash_state(), map()} | {:error, term()}

Synchronizes the affected collection, encodes and sends a mutation patch, then applies the acknowledged change locally and schedules a background refresh. Operations for the same store collection are serialized.
