One entry per attempt
The array of attempts, each with its own state, outcome, codes, addresses and timing — the heart of the result.
In detail
A message that succeeded on the third try arrives with three entries, and the first two say what went wrong. That is what makes bounce analysis possible at all: the final outcome alone would hide the receiver's actual complaints. It is published only when the message is finished. While it is still being retried, the attempts exist nowhere but the send log — the single most important limitation of this telemetry, and the reason Hub's collector reads a file as well as a queue.
