/**
 * Pipeline types — what a memory pipeline preset returns to the wire layer.

 * The wire layer (Layer 5) mounts these two flowcharts as subflows inside
 * the agent's main flowchart:
 *   - `read` runs beforeTurn — produces `scope.formatted` for injection
 *   - `write` runs afterTurn — persists `scope.newMessages`
 *
 * Having BOTH returned as a bundle keeps the two sides coupled to a
 * single store/config choice: you can't accidentally use
 * `.memory(definition)` with `preset2.write` and end up
 * writing to a different store than you read from.
