Shape

A caller builds a [[src/PuduLangResilience/Pipeline|pipeline]] from an array of [[src/PuduLangResilience/Strategy|strategies]], outermost first, and runs callbacks through it. Each strategy wraps the next; the innermost wraps the callback. Every layer answers an Outcome, so a rejection by one layer is a value the layers outside it judge like any other outcome.

Effects reach strategies only through the [[seams/Runtime]] the pipeline lends them: its clock, its randomizer, and its telemetry reporter. State that outlives one call (a circuit, a limiter's permits, a registry's pipelines) lives in [[src/PuduLangResilience/Utils/Shared]] values and is changed only under their locks.

Layers

Domain/ performs no effects and imports no public module. Public modules import one another only toward the core: strategies use Pipeline's types through Strategy, never the reverse.
