StaticComputeSHA-256 identifying a pipeline version: the pin's prompt, prompt version, primary model, parameters and spec.
StaticComputeSHA-256 of the prompt parameters (copied field by field, so an entity object hashes like a plain one).
StaticComputeSHA-256 of the spec parts that change what is computed or written, the OutputMapping text, and an escalating Decision pipeline's target pin hash (the target computes the escalated answers).
the target's ComputeHash; null when the pipeline does not escalate
StaticSelectThe highest-priority Active prompt model (ties broken by normalised model ID), or null when the prompt has none.
The pipeline pin's selection and hashes. Every method is static and takes plain data (pins are built as literals).
