I wish you guys would stop repeating that nonsense. The contract conditions are independent, and you do not need to build a new craft to satisfy the orbit requirement. This is a technical question about the accuracy of orbits, not an "I didn't read the contract, halp pls" question. All of the contract's orbital parameters as well as my sat's orbit are in the OP. If you don't know how to read them and don't even know how the contract system works, please don't bother answering. In any case, I tested this in a clean save and the orbit was recognized without issue. This appears to be an issue with either FMRS, Coherent Contracts, or Contract Configurator. When I reloaded my career without those addons, it recognized the orbit as expected. Here we can see that you can complete the orbit/stability requirements without a valid ship:
