What term describes a condition that is not final or fully agreed upon?

The term "tentative" is appropriate for describing a condition that is not final or fully agreed upon because it conveys the idea of something being uncertain or subject to change. When something is deemed tentative, it indicates that there is still ongoing consideration or deliberation, and a final decision has not yet been made. This aligns with situations where agreements or conclusions are still in the process of being formed, thus not yet definitive.

In contrast, "ambiguous" refers to a lack of clarity or the possibility of multiple interpretations, which does not specifically imply that an agreement is being reached. "Preliminary" suggests that something is introductory or preparatory, indicating an expectation of further development, but it might not capture the sense of uncertainty as forcefully as "tentative." The term "conclusive" stands in opposition, indicating that something is definitive and final, which directly contradicts the idea of being not fully agreed upon.
