Starfleet holodecks

You decide that you and your crew have done enough to aid the Tarrgarans with finding a solution. Likewise, you understand that the risk of lossing this data could spell the end for the Tarrgaran ship. So you pass the information and the code to the Tarrgarans and remain on hand to lend support if it should be required.

Eventually, the Tarrgarans had to give up their efforts and with a communicae by the Enterprise, to the Tarrgaran home world, a second ship was dispatched to resuce the stranded crew. Unfortunately they had to tow the first vessel back to port and a complete systems overhaul was required to make the ship useable again.

At the end of the day, there were no lost lives, you avoided a conflict, and laid the groundwork for a future relationship between the Tarrgarans and The Federation.
