What can be shared
Goals and goodwill
Both parties want the joint activity to succeed and genuinely intend to cooperate.
A dissociation
Shared goals + goodwill ≠ relational alignment
Two people can want the same thing and sincerely want to cooperate while disagreeing about the rules of their relationship.
Cooperative motivation does not determine authority, reciprocity, obligation, autonomy, permission, or the expectations through which cooperation is organized.

What can still conflict
Relationship rules
They may disagree about who decides, what each owes, which actions require consultation, or what treatment the relationship permits.
A simple case
The collaborators agree on the project but not on who decides.
Imagine two collaborators who both care deeply about producing a good piece of work.
One understands the relationship as an equal partnership in which major decisions require agreement. The other understands it as a leader-and-assistant relationship in which consultation is welcome but final authority belongs to the lead.
Neither person needs to be selfish or uncooperative for repeated conflict to follow.
What this reveals
Cooperation itself has to be organized.
A shared goal narrows what the parties are trying to accomplish. Goodwill supplies motivation to work together.
Neither specifies the relational grammar through which decisions, favors, resources, authority, and obligations are interpreted.
