If someone asks who did the work, give the real breakdown, even if your slice was small.

An accurate account protects everybody, including you. Inflating your share is tempting when the work went well, and shrinking someone else’s is usually an omission rather than a decision, but either way the record that goes forward is wrong and people are relying on it. Being the one who reports straight is quietly valuable.

Say the actual split, names attached, including the parts that were not yours. If your slice was small, say that too, without apologising for it. People who do this get asked more often, because what they say can be used.
