Looks good 👍 Will leave it to @ahnaguib to give final approval. |

What's the reason for not relying on pushData() failing instead of checking here?

The issue is that getData() relies on the time that the payload was added to the market-oracle contract, while here we check the time the data was added to the Tellor system. We could theoretically take an old Tellor value and push a report, which will be accepted on getData.
It's another layer of protection to ensure the data is fresh.

How about if one of them is valid, it pushes it after purging?

We will add that to the job. After we purge a report, we'll check if we have a valid value and push it again

can you add new lines to all the files to keep the linters happy?

Hey am I missing something or should the report only get pushed if retrieved is true?

retrieved is true if the value count is greater than 0. TellorID 10 has months of data with a value count of over 4500, so retrieved will always be true when using the current Tellor contracts.
Hello!
I just set the truffle project and created the basic contracts for the conector.
