It is possible for subsequent deliveries of the same `build_finished` data to imply different outcomes. For example, if the build fails, is restarted, and then succeeds. In this scenario the `build_finished` events will be delivered at least twice, once for the failure and then once for the success.
### `eval_started`
* **Payload:** Exactly three values, separated by the two-character string `\t` (ie: not a tab): an opaque trace ID representing this evaluation, the name of the project, and the name of the jobset.
* **When:** At the beginning of the evaluation phase for the jobset, before any work is done.
* **Delivery Semantics:** Ephemeral. `hydra-notify` must be running to react to this event. No record of this event is stored.
### `eval_added`
* **Payload:** Exactly two values, separated by the two-character string `\t` (ie: not a tab): an opaque trace ID representing this evaluation, and the ID of the JobsetEval record.
* **When:** After the evaluator fetches inputs and completes the evaluation successfully.
* **Delivery Semantics:** Ephemeral. `hydra-notify` must be running to react to this event. No record of this event is stored.
### `eval_cached`
* **Payload:** Exactly one value: an opaque trace ID representing this evaluation.
* **When:** After the evaluator fetches inputs, if none of the inputs changed.
* **Delivery Semantics:** Ephemeral. `hydra-notify` must be running to react to this event. No record of this event is stored.
### `eval_failed`
* **Payload:** Exactly one value: an opaque trace ID representing this evaluation.
* **When:** After any fetching any input fails, or any other evaluation error occurs.
* **Delivery Semantics:** Ephemeral. `hydra-notify` must be running to react to this event. No record of this event is stored.
