Choosing Between Losing a Record and Processing It Twice

The outcome explicitly asks the learner to say 'whether a record can be lost or processed twice and what it costs to prevent each'. This node is the direct carrier of that clause: it names the two regimes and prices both. It also gates the rest of the sub-domain, because idempotency, deduplication windows and effectively-once only make sense as investments made on top of a deliberate at-least-once choice. It sits one tier above the ambiguity node and below everything that engineers around it.
