## What happened

Job already in a terminal state; settlement runs at most once (COW-2286).

This is the receipt's `what` text, produced by the node's `ExecutionError::JobAlreadyComplete`.

## Why it happened

The node rejected the operation with `E1616` (category `runner`, Runner / Consensus). The receipt's `why` field carries the specific cause and `context` carries structured details, when the emitter attaches any.

The normative rule is in CIP-2.

## How to fix

This job already settled (settlement runs at most once); don't resubmit a result or re-trigger settlement for it.
