ADR-0003-pipeline-order.md
ADR-0003 — One documented order for every layer
type: adr status: Accepted tags: [adr]
Context
Behaviors, processors, and exception components can be open or per kind and registered in any order. Their order changes what each observes.
Decision
Outermost first: exception actions and exception handlers (actions outside for ForUnhandled, the default, inside for ForAll), pre-processors, post-processors, then behaviors open and per kind in registration order, then the handler ([[domain/Pipeline]], [[src/PuduLangMediator/Compose]]). Within each layer, open and per-kind components keep their registration order ([[src/PuduLangMediator/Domain/Order]]).
Consequences
- Exception components see failures from every layer, including processors.
- Post-processors run only on a value and before any behavior sees it on the way out.
Rejected
- Processors as ordinary behaviors: their place would depend on where they were registered.
