 3. **Pipeline's `add_node()`**: When added to the pipeline, users can specify some parameters that have to be given only to that node specifically. They will override the node instance's parameters, but they will be applied only in that specific location of the pipeline and not be applied to other instances of the same node anywhere else in the graph.

 We will progressively add nodes to this `haystack.v2` package and build a folder structure under it (`haystack.v2.nodes`, `haystack.v2.stores`, ...) version after version, until we believe the content of the package is usable. Documentation will be built in parallel and we will progressively start pushing users towards the 2.0 API.
 Power users like dC and other Haystack experts will be able to test out these changes from the start and provide feedback while still in Haystack 1.x.

 The contract is quite narrow to encourage the use of specialized nodes. `DocumentStore`s' primary focus should be storing documents: the fact that most vector stores also support retrieval should be outside of this abstraction and made available through methods that do not belong to the contract.

 The design above derives from one Canals limitation: component’s sockets need to be all known the latest at `__init__` time, in order for the connections to be made and validated. Therefore, we need to know all the prompt variables before building the pipelines, because the prompt variables are inputs of the `run()` method.

 If we decide that Canals should support again such components, we would be able to rewrite `PromptBuilder` to take a prompt as its input parameter and just accept any other incoming input, on the assumption that users knows that they’re doing.

 As with evaluation in Haystack 1.x, we reaffirm the core idea of implementing different pipelines for different concerns. We consider evaluation a separate process and consequently separate the execution of RAG and the metric calculation into two different pipelines. This allows for greater flexibility - for instance, the evaluation pipeline could contain an additional component that routes the inputs to different evaluator components based on certain criteria, etc. Another example would be the ability to convert the inputs from/to different formats before passing them to the evaluator.
 
-A further advantage of this approach is that any tool we develop in the future to facilitate introspection and observability of pipelines can transparently be appled to evaluation as well.
